Dead Ringer – Bosco Wong, Chrissie Chau

Liang Xi (played by Zhou Xiuna) and Wei Xiaochen (played by Zhou Xiuna) are a pair of identical twin sisters. Due to their parents' troubled relationship leading to divorce, the sisters were separated. As they grew up, Liang Xi became an insurance claims manager. After moving to Singapore, she checked into a hotel, only to be unexpectedly kidnapped there.

On the other hand, Wei Xiaochen, who had accompanied her mother to Singapore from a young age and had no contact with Liang Xi, discovered Liang Xi's body in a human trafficking and prostitution den she raided during her mission. Seeing Liang Xi's face identical to her own, Wei Xiaochen couldn't help but shed tears. Despite opposition from her superiors, she insisted on investigating the case that had escalated from prostitution to organ trafficking.

Brandon, a forensic expert, confirmed through DNA analysis that Liang Xi was indeed Wei Xiaochen's sister. He vouched for Wei Xiaochen, assuring that he would not reveal their relationship. Reluctantly, the superior allowed Wei Xiaochen to continue pursuing the case.

During the interrogation of the arrested head of the prostitution ring, under Wei Xiaochen's threats, he admitted to his involvement in human trafficking for prostitution, but denied any connection to Liang Xi's death. Only when Wei Xiaochen threatened him with a gun did he reveal that a black-market doctor known as "Pork Butcher" had removed Liang Xi's heart. Following this lead, Wei Xiaochen traced "Pork Butcher" and discovered that he was just the surgeon, unaware of where the harvested hearts were sent. The one responsible for directing "Pork Butcher" was a professional hitman known as the "Cleaner."

Wei Xiaochen, with a face identical to Liang Xi's, was mistaken by the hotel manager as Liang Xi. While inspecting the room in disarray, Wei Xiaochen suggested checking the surveillance footage, but unfortunately, the cameras were malfunctioning. However, Wei Xiaochen learned that on the day Liang Xi arrived at the hotel, she received a parcel with "RL" written on it. The hotel also found Liang Xi's lost phone. Wei Xiaochen hoped that Liang Xi had left clues for her and used Liang Xi's fingerprints to unlock the phone.

Ma Jiaming, Wei Xiaochen's boyfriend and a tech department employee, opened Liang Xi's private social media accounts to provide Wei Xiaochen with insights into Liang Xi's past. Seeing a photo of the two sisters, Wei Xiaochen felt even more sorrowful. Investigating further, she found messages from someone named Yuan Shengjie (played by Huang Zongze) to Liang Xi, leading her to investigate Yuan Shengjie.

Upon arriving in Singapore, Yuan Shengjie sought out Zhang Jianguo. After locating Roger's residence with Zhang Jianguo, they discovered the place in disarray, with no sign of Roger. Yuan Shengjie noticed someone was following him and managed to take a photo, but it didn't yield any valuable information. Wei Xiaochen was trailing Yuan Shengjie, capturing him in her photos, and also noticed a person on a motorcycle following him. At the police station, Yuan Shengjie glimpsed Wei Xiaochen and tried to follow her but lost her. Zhang Jianguo informed him that this floor was off-limits without police authorization.

A year ago, while disrupting a money laundering operation, Yuan Shengjie chased after documents thrown out of a window by criminals. He witnessed Liang Xi picking up the documents and, fearing she might be involved, brought her to the police station. After confirming her innocence, Yuan Shengjie apologized. Liang Xi, smitten with Yuan Shengjie, left her contact information, and they quickly became a couple.

Concerned about Liang Xi's disappearance, Yuan Shengjie dialed her number but received no response, leaving him puzzled. Yuan Shengjie and Zhang Jianguo pretended to have found evidence, drawing out the black-clad individuals who had been following them. Wei Xiaochen, driving a car, caught up and forced them to stop, but before she could interrogate them, someone shot and killed the black-clad individuals. Feeling regretful, Wei Xiaochen realized that Liang Xi had sought her help in a moment of danger, but since no one was at home, she missed the distress signal.

Now, Roger called Liang Xi to return a USB drive. Wei Xiaochen, assuming Liang Xi's identity, met with him, witnessing Roger being silenced. She attempted to chase the assassin but couldn't apprehend him. However, the assassin left behind something.

Yuan Shengjie deliberately left his business card in the bar, successfully prompting an informant to reveal Sisi's whereabouts. However, by the time he and Zhang Jianguo arrived, Sisi had already died. Holding Sisi's photo, Yuan Shengjie inquired about anyone who knew her. Accidentally bumping into a delivery person, after agreeing to compensate for the damage caused, the delivery person informed Yuan Shengjie that Sisi had lived here for many years and that a stranger had visited her on the day she died. Showing a photo of a man, the delivery person identified him as Sisi's frequent visitor, recognizing only his face as he always wore a duckbill cap.

Wei Xiaochen faced off with an assassin and was certain that the killer was trained personnel. She tasked Ma Jiaming with collecting a list of individuals who had undergone sniper training. After Zhang Jianguo killed Roger, he immediately called to demand the remaining payment, with the other party questioning if he left any traces. Though Zhang Jianguo knew he had lost his bracelet, he confidently assured that there were no traces left. Returning to the police station, Zhang Jianguo encountered Wei Xiaochen, who, with a single remark, exposed that she sustained injuries while fighting criminals. She was repeatedly questioned by Zhang Jianguo about finding any leads. While Wei Xiaochen found Zhang Jianguo's inquiries excessive, her fellow police officers considered it normal curiosity given the nature of the case.

Unaware of Liang Xi's murder, Yuan Shengjie finally reached Liang Xi by phone, questioning why she hadn't answered his calls in the past few days. Posing as Liang Xi, Wei Xiaochen inquired about Roger's news, but like Yuan Shengjie, she had only surface-level knowledge about Roger and used the excuse of poor signal to end the call. Just as Wei Xiaochen accelerated away, Zhang Jianguo appeared, leaving Yuan Shengjie somewhat puzzled. However, he didn't dwell on it and returned to the hotel to pack.

The delivery person, seeing that Yuan Shengjie indeed fulfilled his promise to compensate, developed a favorable impression of him. Yuan Shengjie gave his business card to the delivery person, who remembered the assassin's call mentioning the name "Yuan Shengjie." As the delivery person left, he encountered Zhang Jianguo in the corridor. Remembering that it was Zhang Jianguo who went to see Sisi that day, he quickly hid in a safe passage to call Yuan Shengjie. Upon hearing that Zhang Jianguo was the killer, Yuan Shengjie tried to remain calm, confirming with the delivery person that he hadn't mistaken the identity, and then hung up. Zhang Jianguo questioned Yuan Shengjie about the recent call, and Yuan Shengjie, under the pretext of someone informing him, claimed that his girlfriend went to the movies with someone else, diverting attention from the matter.

Yuan Shengjie promptly returned to Hong Kong, suspecting Zhang Jianguo as the killer of Sisi and Roger. When he learned that Zhang Jianguo's wife had kidney problems and needed a significant amount of money for surgery, his suspicion deepened. However, falsely accusing a police officer is a serious crime, so Yuan Shengjie anonymously emailed the Singapore police, urging them to cooperate in verifying whether Zhang Jianguo was the murderer. Wei Xiaochen, through a thorough investigation of thousands who underwent sniper training, ultimately pinpointed Zhang Jianguo. Consequently, she convinced her superior to deploy based on the information in the anonymous email.

Zhang Jianguo received a message claiming to have a video of him committing the crime, demanding fifty thousand. Desperate for money, he agreed to meet, ready to shoot at any moment. Wei Xiaochen, using Zhang Jianguo's continuous requests for the informant to change seats, pinpointed Zhang Jianguo's location. At a crucial moment, she prevented Zhang Jianguo from shooting the informant, but as she gained control, a stack of papers fell in front of her. Seizing the opportunity, someone shot and killed Zhang Jianguo, once again leaving the case in a stalemate.

To uncover the truth behind Liang Xi's murder, Wei Xiaochen sacrificed everything and persuaded her superior to arrange for her to assume Liang Xi's identity in Hong Kong. Yuan Shengjie felt that Wei Xiaochen was acting differently but attributed it to her injury, not paying much attention. To integrate into the company, Wei Xiaochen forced herself to remember her current colleagues. However, even though she distributed gifts based on the closeness of relationships upon arriving at the company, she still couldn't remember her own workspace, surprising her colleagues. To handle the situation, she had already claimed to have some memory loss. Feifei, waiting outside Liang Xi's house for hours, became suspicious upon her return and, after relieving himself in a hurry, instinctively questioned Wei Xiaochen's true identity.

Wei Xiaochen had never dealt with insurance before, and since she was unaware of some of Liang Xi's work, when her supervisor approached her to submit a report, she was at a loss. The supervisor, dissatisfied with Liang Xi, warned Wei Xiaochen that although she was introduced by Dickey, she still had to write the work report. A colleague sitting nearby reminded Wei Xiaochen that she had already prepared the report and asked her to take it out of the drawer. When the supervisor saw the report, his expression softened. He questioned why Wei Xiaochen didn't bring it out earlier, and she could only say that she forgot.

Yuan Shengjie reported the recent work to his superior, but the police officer was dissatisfied and ordered him to stop the investigation. At the same time, he requested that the deaths of Edward and Simon be classified as accidents. Yuan Shengjie couldn't resist his superior's orders, but deep down, he was unwilling. He knew his friend Wang Mu very well, and Wang Mu was someone who would consider even the possibility of an avalanche while skiing, so how could he easily meet with an accident? It turned out that Edward, Simon, and Luo Jie had initially gone to the tunnel together. However, Luo Jie went to the hospital due to stomach pain and narrowly escaped the explosion in the tunnel. Edward and Simon were not as fortunate and died in the tunnel explosion. Yuan Shengjie suspected that someone might have wanted to eliminate all three, especially since not only did the equipment malfunction that day, but even the surveillance footage storing the equipment had issues. So, despite the pressure from his superior, he decided to secretly investigate. The team members recognized Yuan Shengjie's character and expressed their willingness to help.

Wei Xiaochen learned that Dickey was married, but from the conversations of her colleagues, it was evident that Dickey had intentions toward her. Wei Xiaochen quickly met with Dickey, who, under the pretext of introducing her to more executives, invited her to attend a banquet. Wei Xiaochen decided to attend the banquet and dressed up for the occasion. Feifei happened to run into Wei Xiaochen, who was about to leave, and couldn't help but worry about Dickey, the old pervert, making a move on her. Wei Xiaochen, using the excuse of seeking a promotion, got into Dickey's car. Dickey lusted after Wei Xiaochen's beauty, and during their conversations about Limin Company, Wei Xiaochen asked about it. Unexpectedly, everyone unanimously refused to speak. Dickey's face darkened, and he placed his hand on Wei Xiaochen's waist. Wei Xiaochen quickly found an excuse to leave, only to run into Tu Wenno, who was holding his chest. Tu Wenno felt that Wei Xiaochen looked familiar, although they had clearly never met. Wei Xiaochen learned that Tu Wenno was the president of Limin and took the initiative to take him to the banquet. Seeing Wei Xiaochen quickly getting close to Tu Wenno, Dickey couldn't help but look displeased. Wei Xiaochen obediently stood by Dickey's side. Mr. Yang, the new president of the field, arrived uninvited and wished Tu Wenno good health with hidden meaning.

After the banquet, Dickey held Wei Xiaochen and wanted to take her home. At this point, Wei Xiaochen was a bit tipsy, but she still managed to refuse Dickey. Dickey naturally didn't want to give up and tried to forcefully take Wei Xiaochen, but Tu Wenno had something to discuss with him and sent Zhao to escort Wei Xiaochen. Dickey had no choice but to stay. When Wei Xiaochen returned home, she was already exhausted. She keenly heard some movement in her house, immediately preparing to defend herself. Unexpectedly, Feifei, sensing that something was wrong with her, confronted her with a knife, demanding her true identity. Wei Xiaochen didn't want to continue the deception and revealed Liang Xi's murder. As Liang Xi's elder sister, she wanted to investigate the truth and give Liang Xi justice. Feifei was unwilling to believe it. Wei Xiaochen then showed him a photo that Liang Xi had kept in the wardrobe as evidence. Feifei was very sad, sitting on the ground and crying. Wei Xiaochen was worried that Feifei couldn't overcome it, but the next day, he made breakfast for her, wanting to find out the truth and seek revenge for Liang Xi.

Feifei turned out to be a tracker skilled in using computers to gather information. He got to know Liang Xi due to business dealings, and later, they gradually became friends, deciding to live together in the same house. Feifei reminded Wei Xiaochen that even though she looked a lot like Liang Xi, their habits were different. He decided to start with dressing to make Wei Xiaochen more like Liang Xi. Wei Xiaochen asked Feifei to help her edit a video. She used this video to threaten He Zhiyi, accusing him of not warning Edward and Simon about the unsafe methane levels in the tunnel, which led to their deaths. She wanted He Zhiyi to tell the truth, but He Zhiyi insisted that his recorded confession was truthful. He Zhiyi felt uneasy, and when he walked near his home with an annoyed expression, he saw Yuan Shengjie inquiring about his wife's information. Yuan Shengjie wanted to take him to the police station for questioning, making He Zhiyi even more anxious.

Wei Xiaochen pressed on, but He Zhiyi insisted that he did not harm Edward and Simon. He revealed that on that day, he received a mysterious call, and as soon as he pressed the intercom, it exploded. Wei Xiaochen and Yuan Shengjie believed that the person making the mysterious call was the killer and decided to investigate in that direction.

Wei Xiaochen and Feifei analyzed the tunnel map provided by He Zhiyi, inferring that someone outside the tunnel was using binoculars to monitor Edward, Simon, and Luo Jie. They speculated on the observation point based on the terrain. Yuan Shengjie's analysis aligned with Wei Xiaochen's, and when she went to find him, looking at the markings on the map made her more certain of her conjecture. Yuan Shengjie had already contacted the telecommunications company and would soon obtain information. From Wei Xiaochen's words, he sensed that she was not just an insurance investigator but more like a detective. He advised Wei Xiaochen not to get involved in the case and let the police handle it. However, Wei Xiaochen knew that Yuan Shengjie was also secretly investigating and proposed mutual assistance. Yuan Shengjie tried to embrace Wei Xiaochen, but she rejected him. He felt a bit puzzled but didn't dwell on it.

Wei Xiaochen and Feifei conducted on-site inspections outside the tunnel. They discovered a location with a clear view of the tunnel entrance, which was very secluded. They encountered no vehicles while going up and down the mountain, but Wei Xiaochen noticed a surveillance camera. Feifei took a photo, hacking into the camera with a black code. Wei Xiaochen saw three cars passing through the surveillance footage. She immediately locked onto one of the commercial cars because she vividly remembered that it was Dickey's car from the day of the banquet. Now recalling Zhang Jianguo's words, she became more convinced of Limin Group's involvement in the matter. Wei Xiaochen speculated that Liang Xi had approached Dickey for another purpose. With the information she currently possessed, she needed to get close to the high-ranking members of Limin to gather intelligence. She planned to continue approaching Dickey in Liang Xi's identity. When the superior learned that Yuan Shengjie was secretly investigating the tunnel explosion case, he asked him to stop. However, Yuan Shengjie had surveillance footage proving that Dickey's car had stayed near the tunnel explosion site for thirty minutes, giving a reason to suspect Dickey. The superior requested Yuan Shengjie not to implicate himself and tacitly allowed him to continue the investigation.

Wei Xiaochen went to meet Dickey as per his invitation. Dickey implied that if she didn't share a hotel room with him, she shouldn't expect a promotion. To uncover the truth, Wei Xiaochen reluctantly went to the hotel with Dickey. Yuan Shengjie's subordinates happened to capture a photo of Dickey and Wei Xiaochen entering the hotel together. Once inside the hotel room, Dickey immediately locked the door and tried to get intimate with Wei Xiaochen. Wei Xiaochen quickly used the excuse of going to take a shower to hide in the bathroom. She heard movements in the room, knowing that Dickey had lustful intentions and wouldn't give up easily. Looking at the shower gel in the bathroom, she deliberately made the floor slippery, then called Dickey to come in. Dickey, not realizing it, slipped and got injured. Naturally, he couldn't get close to Wei Xiaochen anymore. When Yuan Shengjie saw the photo taken by his subordinates, he was puzzled. Seeing Wei Xiaochen helping Dickey out and getting into a car, he immediately took Dickey and Wei Xiaochen back to the police station, claiming that Dickey was inciting someone without a driver's license to drive.

Facing Yuan Shengjie's surveillance video, Dickey claimed that his car was at the car wash on the 23rd and 27th and wasn't in use. He evaded Yuan Shengjie's questions and quickly arranged for a lawyer to bail him out. Wei Xiaochen, knowing Yuan Shengjie's suspicions, assured him that she didn't do anything wrong. However, she still got a promotion, attracting the attention of Dickey's legitimate wife. Dickey's wife came to the company, accusing Wei Xiaochen of being a third party and ruining her family. The incident caused a stir in the company and caught the attention of Tu Wenno. Tu Wenno instructed the security to handle it and prevent Dickey's wife from causing more trouble. At the same time, he learned that Dickey's phone was unreachable, adding more speculation in his mind.

Yuan Shengjie found a photo of Wei Xiaochen with Simon from six years ago, taken at a place called "Green World." He suspected that there was a past relationship between Wei Xiaochen and Simon. Holding the photo, he went to find Wei Xiaochen. Wei Xiaochen explained that the method of insurance claims varied depending on the cause of death, and she suspected that Simon's death was not simple, prompting her risky investigation. If Yuan Shengjie couldn't accept it, they could part ways. Following the lead of the "Green World," Wei Xiaochen found a farm. As soon as she appeared, she was warmly welcomed by the people on the farm. Tina, the farm owner, was very worried about Liang Xi. Seeing Wei Xiaochen appearing as Liang Xi, she mentioned the documents Liang Xi had sent her. Wei Xiaochen obtained the documents, finding multiple layers of encryption. In a hurry, she went to seek Feifei's help. At this moment, Feifei was being chased by debt collectors, on the verge of having his hands disabled. Wei Xiaochen, like a goddess, effortlessly defeated the debt collectors. Feifei admired her greatly. After examining the documents, Feifei realized that it would take several days to decrypt them, making Wei Xiaochen anxious.

President Yang Junxiong of the New Territory ambitiously announced his plan to vigorously develop real estate. Just as everyone was celebrating, his brother appeared on the scene and directly halted the plan, putting it on hold indefinitely. Yang Junxiong learned that his brother received a threatening package but dismissed it as a prank. However, his brother refused to risk his only daughter as a bet, leaving Yang Junxiong in a dilemma.

Tuo Wenno's sister, Tuo Wenya, was once kidnapped. The kidnappers didn't demand a ransom but asked Tuo Wenno to give up the development of a piece of land. Building houses there would bring Tuo Wenno a profit exceeding ten billion yuan. However, to ensure his sister's return, he chose to abandon that project. After Tuo Wenya returned, she refused to go home and lived alone in a house on the outskirts, suffering from a mental illness. When Yuan Shengjie inquired about the situation, Tuo Wenno requested him not to bring a phone inside. Tuo Wenya clearly did not want to see Yuan Shengjie. At first, she avoided coming out, but upon hearing a cellphone ring, her emotions spiraled out of control. She kicked Yuan Shengjie and Tuo Wenno out of the door, vomiting alone.

Wei Xiaochen, assuming the identity of Liang Xi, was with the people from the Green World. She inadvertently heard them mention the reason for the New Territory's construction halt. Although not explicitly stated, everyone assumed that Liang Xi was informed and thanked her for helping achieve this favorable outcome. Wei Xiaochen recalled that Feifei had mentioned Tuo Wenno's sister, Tuo Wenya. Tina admitted that they had captured Tuo Wenya but claimed that Liang Xi had requested them not to use torture. Wei Xiaochen didn't believe Liang Xi would do such a thing. That night, she sneaked into the Green World's prison. Just as she was earnestly taking photos, Yuan Shengjie also arrived. Seeing Wei Xiaochen in black clothes, Yuan Shengjie immediately attacked her. After a brief struggle, Yuan Shengjie tore off Wei Xiaochen's mask. He felt that the eyes he saw in the dark were familiar. Back at the police station, he couldn't resist covering the part of Liang Xi's photo below the eyes with a cloth, confirming his suspicions. However, he didn't want to alert the enemy and decided to double-check. So, he took Wei Xiaochen to the hospital, expressing concern about hospital germs. He made her wear a mask, intending to have her change it. However, Wei Xiaochen had already seen through Yuan Shengjie's attempt to obtain her DNA.

Feifei, seeing the marks on the chair in the photos brought back by Wei Xiaochen, was horrified and frightened. Dickey, still having malicious intentions, arranged to meet Wei Xiaochen in the car. After dismissing the driver, he locked the car doors. Wei Xiaochen intended to leave but found the doors locked, so she had to endure. Unexpectedly, Dickey directly hugged her and tried to get close. Wei Xiaochen resisted and pushed him away. Yuan Shengjie received a call from Axi, knowing that Dickey had taken advantage of Wei Xiaochen. Initially, he thought about letting Axi intervene, but considering that Wei Xiaochen was not ordinary, he wanted to observe to confirm his suspicions. However, Axi couldn't bear to watch and decided to help Wei Xiaochen.

Yuan Shengjie knew that Wei Xiaochen had been taken advantage of by Dickey and went to find her. He wanted to get close to Wei Xiaochen, but she, under the pretext of going to the Green World the next day, refused Yuan Shengjie's offer to stay overnight. She also resisted Yuan Shengjie's farewell kiss, further convincing him that Wei Xiaochen had secrets. Yuan Shengjie noticed a cup that Wei Xiaochen had used and used it for comparison, wanting to confirm if Wei Xiaochen was the one wearing the mask. The next day, as soon as Wei Xiaochen arrived at the Green World, she saw Tina destroying evidence in the secret room. Although she wanted to save, she could only wait. Yuan Shengjie unexpectedly arrived at the Green World. When the members of the Green World learned that Yuan Shengjie was a police officer, they couldn't help but feel uneasy. Ah Zhong, an honest person, was disturbed by a sudden noise while walking in the garage that night. Wei Xiaochen took advantage of Ah Zhong's nervousness and abducted him, extracting information about the torture Tuo Wenya endured that day.

In order to smoothly proceed with the case, Wei Xiaochen released Ah Zhong and went to persuade Tina to allow Yuan Shengjie to intervene in the case and investigate Limin. Yuan Shengjie had already confirmed through the comparison of the cup and mask that Wei Xiaochen was indeed a skilled individual. To uncover Wei Xiaochen's identity, Yuan Shengjie set up an ambush for her, wanting her to reveal her skills. Tuo Wenno's subordinates were monitoring Wei Xiaochen and Yuan Shengjie. They observed that although the two were a couple, they were not intimate enough, and Wei Xiaochen always unexpectedly shook him off. Tuo Wenno personally tried to test Wei Xiaochen, inviting her to a restaurant. When Wei Xiaochen learned that Tuo Wenno had undergone a heart transplant, she left in a hurry, asking Ma Jiaming to find out which hospital in Singapore performed the transplant on the day Liang Xi died.

Wei Xiaochen knew that Yuan Shengjie suspected her, but she didn't have time to explain. She took Yuan Shengjie to find Feifei, wanting him to see the contents of the decrypted USB drive. When Wei Xiaochen and Yuan Shengjie arrived, Feifei's house was in chaos, showing clear signs of being searched. Wei Xiaochen worried that Feifei had been kidnapped. At that moment, Fage called, stating that he had Feifei and demanding 600,000 yuan for his release. Hearing Feifei's screams on the phone, Wei Xiaochen became anxious. While Fage was beating Feifei, he discovered a USB drive that had fallen from him. Fage forced out information about artificial island construction using nuclear radiation-contaminated sand and contacted Weiting Zhao for a deal.

Yuan Shengjie and Wei Xiaochen, carrying the money, went to rescue Feifei. After the other party checked the money, they reneged. Yuan Shengjie and Wei Xiaochen, skilled in combat, easily rescued Feifei. Learning that Fage took the USB drive to another warehouse for a transaction, they decided to retrieve it. Fage, along with his henchmen, went to trade with Weiting Zhao. Disdainful of Weiting Zhao as a minor character, Fage was surprised to find that the money Weiting Zhao gave him was counterfeit. He intended to kill him to silence him, but Fage was no match for Weiting Zhao and was killed in the confrontation. Weiting Zhao learned about another warehouse with two men and a woman and ordered someone to eliminate them. Feifei, caught off guard, was quickly targeted, but fortunately, Yuan Shengjie and Wei Xiaochen, who had been keeping an eye on him, saved him in time.

Yuan Shengjie arrested Weiting Zhao and took Wei Xiaochen and Feifei back to the police station. Weiting Zhao had prepared an excuse. The box that suddenly appeared behind Axi's car that day was placed by Weiting Zhao, containing evidence of Dickey's bribery and records of hiring someone to commit murder. Since Yuan Shengjie couldn't break Weiting Zhao's defense, he brought Dickey back to the police station for further investigation. Dickey, unaware that his actions were known, tried to defend himself but was cornered. The documents for opening the account bore his handwritten signature, and his fingerprints were on the gas-measuring device. Panicking, Dickey was about to lose his composure when his lawyer comforted him and suggested having Yuan Shengjie provide a witness.

After analyzing the case, Wei Xiaochen, despite suspecting that Liang Xi's heart was transplanted into Tuo Wenno's body, deduced from Dickey and Tuo Wenno's reactions that neither of them knew about Liang Xi's murder. To find the real culprit, Wei Xiaochen had Feifei upload the backup from the USB drive online. Taking advantage of a restroom break, she distracted the policewoman who was watching them. While Feifei was focused on his task, Wei Xiaochen returned with the policewoman, pretending not to see Feifei. Feifei quickly shut down the computer and moved away, but the policewoman noticed Feifei was missing and contemplated whether to call for help. Feifei then stood up, holding his phone, claiming he had dropped it earlier.

Due to insufficient evidence, Yuan Shengjie couldn't arrest Dickey, so he had to let him go. Feifei was also free to leave, leaving only Wei Xiaochen behind. Knowing the reason why Yuan Shengjie left her, Wei Xiaochen instructed Feifei to continue what he was doing and stayed behind. Later, she and Yuan Shengjie went to the seaside to feel the breeze. Yuan Shengjie tested Wei Xiaochen's strength, realizing that she had become much stronger. He remembered the incident when Liang Xi was harassed on the street but couldn't push away the intoxicated man, wondering about the significant change in Liang Xi. Wei Xiaochen admitted to deceiving Yuan Shengjie about many things, damaging the trust between them as a couple. She gently suggested breaking up but hoped they could remain good friends. Yuan Shengjie recalled a time when he went to Liang Xi's house and saw her injured. He wanted to take her to the hospital, but Liang Xi refused and politely declined his offer to stay overnight, not knowing how much Liang Xi had hidden from him.

Feifei exposed the news of radiation on the artificial island on the internet, along with Dickey's deeds. Soon, reporters focused on Limin. Tuo Wenno's father, as the chairman, couldn't escape blame and had to step down voluntarily. Tuo Wenno asked Weiting Zhao to handle the matter of the USB drive in the police station and went to find Wei Xiaochen. Convinced that Dickey wouldn't return, he asked Wei Xiaochen to take Limin's place and help him. Sensing danger from Tuo Wenno's words, Wei Xiaochen called Yuan Shengjie to warn him. Dickey's lawyer quickly arrived at the police station, requesting to talk to Dickey alone. After the conversation, Dickey willingly admitted to causing the tunnel explosion.

The TV is reporting the news of Dickey's confession. Feifei, feeling upset, believes that Dickey is just a scapegoat and suspects Yuan Shengjie of being lazy and incompetent. Wei Xiaochen speaks up for Yuan Shengjie, pointing out that the existing evidence does not prove the involvement of others, and since Dickey confessed voluntarily, Yuan Shengjie had no other choice. However, she believes that Yuan Shengjie will not let it end there. At the police station, Yuan Shengjie suggests treating his subordinates to a late-night meal. They are concerned that he might not want to pursue the case further and keep questioning him. While walking, Yuan Shengjie instructs them to eat quickly and mentions visiting Dickey's wife the next day. Excited, his subordinates happily follow him.

Limin Group holds a press conference. Tu Wenno, upon entering the venue, inquires about Liang Xi, who is absent. Tu Wenno, trying to hide his disappointment, announces the details of Dickey's bomb design and the radiation sand on the artificial island to restore Limin's reputation. To appease the public, Tu Wenno donates some land, but reporters remain skeptical, asking sharp questions. When Tu Wenno finishes speaking, Liang Xi is already standing in the audience. Tu Wenno feels better, thinking Liang Xi's move is the right choice, assigning her to take over Dickey's work.

In the office, Wei Xiaochen, as Liang Xi, becomes the manager of Limin and discovers someone spying on her. She quickly closes the blinds to block the view, answers a call from an unknown number cautiously, and arranges to meet with the caller. This incident warns Wei Xiaochen that Liang Xi's identity is more complex than she thought, understanding why Tu Wenno mentioned she was working for another boss. Wei Tingzhao feels that Liang Xi has changed, so he contacts Liang Xi's former boss, An Pei, to confirm her background.

Yuan Shengjie and his team go to find Dickey's wife but discover that their house is empty, and even their daughter has transferred schools with no information about their whereabouts. Yuan Shengjie, now more convinced of his suspicions, knows that Dickey was just a scapegoat, and with his wife and daughter missing, his suspicions are strengthened. Suddenly, the evidence room at the police station catches fire. Yuan Shengjie identifies a woman through surveillance footage, but her face is obscured by a hat. They can only rely on facial recognition to identify her. Wei Xiaochen, aware of the incident at the police station, contacts Yuan Shengjie, hoping he can send her the surveillance photos as Feifei might be able to help.

Yuan Shengjie has already discovered that the woman impersonating a policewoman is Zheng Guizhi. When he arrives at Zheng Guizhi's residence, Wei Xiaochen is already there and finds a work card and a burnt police uniform. Fa Ge, who was shot that day, is not dead and is undergoing treatment in the hospital. Wei Xiaochen discovers that Zheng Guizhi works at the same hospital and, worried about Fa Ge's safety, hurries with Yuan Shengjie to confirm that Fa Ge met Wei Tingzhao that day. They both conclude that Tu Wenno is up to something, but without evidence to arrest him, they can only assign someone to protect Fa Ge. An Pei has evidence of Liang Xi's insurance fraud and uses it to threaten Wei Xiaochen into helping him enter Limin Company. When discussing this matter, Wei Xiaochen notices a nurse wearing different gloves, and her intuition tells her that Fa Ge is in danger. She rushes to catch up but is too late, as Fa Ge has already been injected with a drug, trembling uncontrollably. Axi goes after Zheng Guizhi, shooting her in the leg. Zheng Guizhi, at the stairwell, falls and dies on the spot, and it seems that the lead is about to be lost.

Wei Xiaochen worries that if An Pei goes to Limin, he will see through her identity. So, she joins forces with Feifei to take control of An Pei first. They believe that, given An Pei's character, he must have committed many illegal acts. Liang Xi returns to the insurance company, uses the opportunity of using the computer to let Feifei break through the company's firewall, and then, claiming to have received threatening messages, asks An Pei to delete files. An Pei, concerned about security, logs in to check and is caught off guard by Feifei, who steals all his files. An Pei not only fails to get a good deal from Wei Xiaochen but also gets physically beaten without uttering a word.

Wei Xiaochen wanted to find an opportunity to place a bug. Upon arriving at Limin, she heard her colleague Qiong mentioning the government's collaboration with Yang Junxiong due to the radiation sand on the artificial island. She regretted not buying more of Yang Junxiong's stocks. Just then, Tu Wenno arrived at the company and jokingly reminded Qiong not to borrow money to buy stocks. He then held a board meeting, reprimanding board members for profiting from the radiation sand incident and giving them a warning to continue investing in Limin. Feifei decrypted the contents of the backup on the USB drive and discovered that the radiation sand files had been consistently modified by the same person. In reality, the report had no issues. Wei Xiaochen, puzzled, analyzed with Feifei and concluded that Tu Wenno probably wanted to force his father to step down and become the chairman himself. They considered Tu Wenno a key suspect in the murder of Liang Xi.

Yuan Shengjie had a female subordinate track Wei Tingzhao, but Wei Tingzhao noticed and got rid of her before meeting Tu Wenno. Shortly after Tu Wenno met Wei Tingzhao, he saw Yuan Shengjie and his team approaching the building from the rooftop. Initially thinking it was just an innocent reunion of old classmates, Wei Tingzhao, not wanting Tu Wenno to be targeted by the police, let Tu Wenno leave first. Unexpectedly, when Tu Wenno left in his car, Yuan Shengjie noticed him. To stop Yuan Shengjie, Wei Tingzhao suddenly rushed out, blocking Yuan Shengjie's car. Tu Wenno's car quickly left, leaving Yuan Shengjie feeling both upset and embarrassed. He had no choice but to return to the police station and apologize to the chief. The chief, unhappy with Yuan Shengjie causing trouble, decided to transfer him and his team, instructing him to stop the investigation.

While the office was empty, Wei Xiaochen discreetly placed a bug in Tu Wenno's office and instructed Feifei to keep a close watch. However, Feifei informed her that there had been no sound since Tu Wenno entered the office. Wei Xiaochen thought the bug might be faulty, but in reality, Tu Wenno had already installed surveillance, monitoring Wei Xiaochen's every move. This day, Wei Xiaochen encountered Tu Wenno in the company, and Tu Wenno, with hidden meaning in his words, reminded her not to associate with the wrong person. Wei Xiaochen realized that Tu Wenno had already seen through her. After carefully recalling, she remembered an anomaly with the light in Tu Wenno's office, confirming it was a monitor. While pondering how to handle the situation, Yang Junxiong sent someone to bring her for a meeting.

Learning that Wei Xiaochen had made no progress lately, Yang Junxiong reminded her not to think that getting close to Tu Wenno would solve everything. He mentioned saving her father in the past and revealed that Liang Xi used to work at a mysterious nightclub. If it weren't for him, her father would have died due to lack of money for treatment. Wei Xiaochen expressed loyalty to Yang Junxiong, and upon returning to Limin, she voluntarily surrendered to Tu Wenno, pretending to work for Yang Junxiong but actually assisting Tu Wenno. Tu Wenno appreciated Wei Xiaochen's strategy and immediately gave her a USB drive with information. Wei Xiaochen aimed to infiltrate Yang Junxiong's personal computer, and Feifei tampered with the USB drive. When Yang Junxiong inserted the USB drive into his computer, Feifei successfully infiltrated it, but unfortunately, Yang Junxiong's computer contained only some abusive videos, not what Wei Xiaochen expected.

While organizing files, Yuan Shengjie saw a photo of himself with Liang Xi on the table. He reminisced about their love and a time when he was late for a date, leading to Liang Xi getting angry. Later, they made croissants together, and things got better. They even left behind a precious photo. Feeling sentimental, he went to the bakery and made croissants to give to Wei Xiaochen. When Wei Xiaochen returned home, she saw Feifei eating croissants and learned that they were from Yuan Shengjie. Surprised because she had never mentioned liking them, Feifei informed her that her taste was the same as Liang Xi's, confirming their twin connection.

Wei Xiaochen's father called her, mentioning the disappearance of his good friend, and asked her to call Yuan Shengjie. Wei Xiaochen went alone to the nursing home, where she learned that her father suspected his friend was dead and buried on the opposite mountain. Thinking her father was having delusions, she comforted him, planning to tell Yuan Shengjie about it. However, her father sneaked into the director's office at night and took a photo of an ID card. Wei Xiaochen persuaded the director to let her father stay in the nursing home, but she became suspicious. She had Feifei recover the files from her phone, and indeed, she found the ID card photo her father mentioned, making her take it seriously.

Wei Xiaochen saw so many ID cards and realized that something might be wrong. She sought help from Yuan Shengjie, simultaneously entrusting him to help find someone named "Professor." Yuan Shengjie initially didn't believe that ex-lovers could remain friends, but when Wei Xiaochen thanked him for agreeing to help, he started to believe her. Mentioning the croissants he had previously given her, Wei Xiaochen said they were delicious, and Yuan Shengjie felt they would be even better next time. Yuan Shengjie met with an informant under a secluded bridge. The informant, disguised as a delivery person, had discovered that the Professor was involved in the black market organ trade and was a high-ranking member of a group, rarely appearing in person. The informant deliberately consumed most of the delivered meal and asked Yuan Shengjie not to waste it. After the informant left, Yuan Shengjie checked the leftovers and found contact information for the middleman written on the box.

Yuan Shengjie and Wei Xiaochen went to an arcade to play games, but their minds were elsewhere as they observed people. Unexpectedly, Wei Xiaochen won against Yuan Shengjie, who couldn't believe he lost to someone without a driver's license. Wei Xiaochen noticed someone heading straight for Yuan Shengjie at three o'clock and immediately warned him. Yuan Shengjie prepared for any situation, but the man turned out to be someone who just took out game tokens and insisted that Yuan Shengjie let him play. Sensing they had something to discuss, Wei Xiaochen quickly found an excuse to leave and accidentally saw Ma Jiaming walking hand in hand with another woman. Unable to believe it, she called Ma Jiaming, who took out his phone but refused to answer. Trying to clarify things, she caught up with him and finally confronted Ma Jiaming. Ma Jiaming's companion, seeing Wei Xiaochen, quickly let go, and Ma Jiaming explained that he used to report truthfully about everyone he met, but Wei Xiaochen never shared details about her work as a special police officer. Despite this, he always took care of her when she was injured. Wei Xiaochen, since arriving in Hong Kong, had not contacted him for casual conversations or out of missing him; she only called when she needed his help. Seeing Ma Jiaming firmly holding the hand of the woman beside him, Wei Xiaochen realized her failure as a girlfriend. She sincerely wished him well, feeling lost, she went to a nursing home alone. Watching her elderly father peacefully asleep, she pondered whether coming to Hong Kong, causing Liang Xi to lose Yuan Shengjie, and herself losing Ma Jiaming were all worth it. Overwhelmed by sadness, she couldn't help but cry. Yuan Shengjie, using Feifei's location, found Wei Xiaochen and handed her tissues without asking the reason for her distress. He just told her he would be waiting outside and would drive her home whenever she wanted. Wei Xiaochen fell asleep in Yuan Shengjie's car. He brought her to her doorstep, unwilling to wake her up. He covered her with his own coat and sat in the car throughout the night.

Wei Tingzhao found the organization responsible for targeting Liang Xi to confirm if they indeed killed her. However, the person who carried out the act had already been dealt with, and they were unsure if the deceased was Liang Xi. The Professor was responsible for handling the bodies. Wei Tingzhao promised to pay more, asking them to dispose of Wei Xiaochen cleanly. He also wanted them to establish contact so he could question the Professor. Feifei, the righteous hacker, hooked a big fish—the Professor. He went to meet the Professor, with Wei Xiaochen and Yuan Shengjie following to protect him. Feifei was extremely nervous, almost turning back to confirm their presence, but Wei Xiaochen reminded him not to. Wei Xiaochen's father called, telling her that the people who killed his friend had come to the nursing home. Wei Xiaochen was in a dilemma, unsure whether to rush to the nursing home. Yuan Shengjie arranged for Ah Xi and Ah Min to check the situation at the nursing home. Wei Xiaochen then discovered that Feifei had been taken away. She and Yuan Shengjie had been following Feifei's movements until the signal was lost, causing them to become anxious. They quickly followed Feifei's mention of an industrial building, but couldn't find him. After searching for the building for more than ten minutes, Wei Xiaochen became increasingly anxious. Fortunately, Yuan Shengjie learned from the building administrator that there was a way to the basement. They hurriedly went down and found that Feifei had only been drawn blood from; he was unharmed.

Tu Wenno and Yang Junxiong both received messages from Mrs. Jin asking them to board a ship. Mrs. Jin's spokesperson, Sister Mag, was satisfied with Tu Wenno's performance but displeased with Yang Junxiong's inability to control the Yang family. She scolded Yang Junxiong before allowing them to board the ship.

Wei Xiaochen sneaked into the nursing home at night and noticed a caregiver carrying two bags of garbage outside. As she was about to follow, she discovered that Yuan Shengjie was also there. Quietly, they both trailed the caregiver and overheard them talking about burning things and instructing the deceased not to seek revenge but to find that woman. Wei Xiaochen and Yuan Shengjie thought of Brittany, suspecting her collusion with the organ-trafficking doctor. Feeling a chill, they decided to bring Liang's father back home.

Feifei, at Wei Xiaochen's request, helped take care of Liang's father. After finishing breakfast, Liang's father, forgetting that he had already eaten, believed the packaging on the table was from the previous day. Without saying anything, he left, and Feifei, without grabbing his phone, hurriedly followed. Liang's father led Feifei to the place where the caregivers were burning things the previous night. He had a feeling that his friend might be buried there, so he picked up a nearby branch and started digging, eventually uncovering human bones. Seeing the bones, Feifei felt a chilling sensation and protected himself with his hands, while Liang's father picked up the bones and put them in a bag.

Wei Xiaochen tried calling Feifei, but there was no answer. Worried, she checked the location device she had placed in Feifei's shoe and discovered he was in an unexpected location. Realizing something was wrong, she quickly went with Yuan Shengjie. Following the location, they found Feifei's shoe on a garbage truck. Yuan Shengjie promptly showed his credentials and learned that the garbage was collected from a pet shop on another street. They rushed to the pet shop.

Inside the operating room, Feifei was on the operating table, and two men stood beside him. One of them demanded the doctor take both of Feifei's kidneys. The doctor warned that Feifei would die, but the man insisted. Just as the man was about to start the procedure, Wei Xiaochen and Yuan Shengjie appeared on the surveillance, prompting them to separate. One went to intercept, and the other hid in the operating room. Yuan Shengjie chased the man who had failed to capture Feifei earlier. The man fled, grabbed a passing woman, injured her, and escaped while Yuan Shengjie had to prioritize saving the woman. Wei Xiaochen subdued the doctor in the operating room, handcuffed him to a rack, and questioned him about Liang's father's whereabouts. However, he insisted he didn't know. Feifei, now awake, told Wei Xiaochen that Liang's father should be at the nursing home. Wei Xiaochen rushed to the nursing home, leaving Feifei to handle things there.

Liang's father was captured by the nursing home director, Pan Guodong, and others. They restrained him on a bed and accidentally found human bones in a bag that fell. Pan Guodong was alarmed and quickly forced Liang's father to swallow a large amount of sleeping pills before taking the bones away. Wei Xiaochen and Yuan Shengjie arrived hastily. Pan Guodong couldn't harm Liang's father and, seeing that Wei Xiaochen seemed unaware, followed Wei Xiaochen's request to process Liang's father's discharge.

Feifei narrowly escaped death from the veterinarian, scaring him off in anger. The veterinarian admitted to performing the surgery but claimed ignorance of other details. He mentioned a meeting with someone who was addressed as "sister" over the phone. Both Yuan Shengjie and Wei Xiaochen believed the person addressed as "sister" was Brittany, so they asked Feifei to find a way to hack into her computer. Feifei, disguised as someone checking telephone lines, coincidentally passed by Brittany's company. Brittany instructed her employees to watch the person checking the telephone lines carefully. Seizing the opportunity, Feifei pretended to cough and asked for a glass of water, secretly inserting a USB drive into Brittany's computer, successfully gaining access. Feifei checked the computer files but found everything normal. However, considering Brittany's normal business dealings, it was improbable that she could afford such a good office and the enormous internet usage, suggesting something suspicious.

Wei Xiaochen, aware that Brittany was causing trouble for her, decided to confront Brittany personally. Brittany, facing the agile Wei Xiaochen, instinctively pressed a button under the table. Someone saw Wei Xiaochen's actions and threatened to call the police. Wei Xiaochen had to retreat, but she soon remembered Brittany's unusual behavior. Returning to investigate, she discovered a hidden room behind the button, filled with computers. Feifei examined them and learned that Brittany and Pan Guodong were jointly using the elderly's identity information to launder money. Sister Mag learned about Brittany causing trouble due to personal grievances, leading her to change her base. She directly took action, instructing someone to kill Brittany, plunging the case into confusion once again.
