Butterfly Shadow – Feng Yue, Wei Daxun, He Ziming

In 1938 Shanghai, patriotic Xu Feifan was being chased by Japanese spies after assassinating a high-ranking Japanese official. He was severely injured and encountered Lin Qiuyan who was out at the time. Lin Qiuyan saved him and they hid in the sewer to avoid being discovered by the Japanese. Lin Qiuyan helped stop Xu Feifan's bleeding and took care of him. Xu Feifan was deeply moved and asked about Lin Qiuyan's identity. He admired her courage as a female student who risked her life to save him. Lin Qiuyan also had a good impression of Xu Feifan as a righteous man. With Lin Qiuyan's help, Xu Feifan cleverly evaded the search. Back at their residence, Xu Feifan's brother Liang Xilong bandaged his wounds and advised him to live a peaceful life. Xu Feifan said he couldn't let the Japanese live in peace. He laughed and told Liang Xilong that the little girl who saved him was like a little fairy who helped him escape. Liang Xilong also wanted to join Xu Feifan in his actions, but Xu Feifan didn't give a definite answer. Lin Qiuyan and Zhang Zimo were childhood sweethearts who were both studying in Shanghai.

At the same time, Song Yikun sent Lin Zi to find Lin Qiuyan, but she had already left Shanghai. Lin Zi reported to Song Yikun that he couldn't find Lin Qiuyan and that she had left. Song Yikun immediately decided that he couldn't wait any longer and sent someone to transfer Lin Yixiang's family to Nanjing. He was worried that there would be trouble, especially since Lin Qixuan was a well-known archaeologist and a national talent. The Japanese would not let him go easily. Song Yikun reminded them again that if they found any Japanese people watching around Lin Qixuan's house, they should not take action and immediately discuss a rescue plan with their comrades in Nanjing. Lin Zi didn't understand why they couldn't take action. Song Yikun replied that it would only accelerate the Japanese's use of force against the Lin family, and the consequences would be unimaginable. Lin Zi agreed. Japanese spy Makisai was familiar with Lin Qixuan and came to persuade him to hand over the "Zhuoqin Tu". However, Lin Qixuan had already seen through the true nature of the Japanese, especially after the Nanjing Massacre, which made him hate the Japanese even more.

Zhang Zimo wrote a letter to his sister Lin Qiuyan, revealing that he wants to join the army. Zhang's sister brought him chicken soup and urged him to find someone to settle down with. Zhang insisted that he is grown up and doesn't need her help. He left the letter next to his sleeping sister and left with his luggage.

Lin Qiuyan has not been in touch, causing Song Yikun to lose sleep. The organization has not yet told Lin Yixiang about the situation at home, fearing that it will affect his work. Lin Qiuyan asked Zhou Zhitao to find the killer of her parents, otherwise she will not cooperate to go to Wuhan. After Zhou Zhitao heard Lin Qiuyan's analysis that Mu Zhai was the killer, he believed that Lin Qiuyan had the potential to be a spy. Lin Qiuyan wanted to join the military intelligence special agent, and Zhou Zhitao agreed.

Song Yikun remembered that Lin Yixiang had mentioned Lin Qiuyan before, saying that she had a strong personality like a boy and was very intelligent. Lin Zi thought about it and wondered if there was a possibility that she could join the military intelligence. Song Yikun was deeply troubled.

Lin Qiuyan entered the dance hall in disguise to assassinate Fu Chengbo. However, as it was her first mission, despite her excellent performance in training, she still had many flaws. Lin Qiuyan pointed her gun at Fu Chengbo, but when he pretended to mention his daughter and begged for mercy, Lin Qiuyan hesitated and did not notice that Fu Chengbo had secretly pulled out his gun. Fu Chengbo took advantage of Lin Qiuyan's carelessness and tried to kill her, but was shot dead by Zhou Zhitao on the other side. Zhou Zhitao quickly evacuated with Lin Qiuyan and criticized her for not showing mercy on the battlefield, planning to send her to Chongqing. However, Lin Qiuyan did not want to go and cleverly avoided it. She could not forget the tragic scene of her parents' death and was filled with hatred. She wanted to stay in the special training class and learn skills to avenge her parents. Song Lianqing reported on the situation of the research institute and gave the construction diagram to Song Yikun. When Song Yikun immediately analyzed and deployed the action plan, Lin Zi brought an urgent telegram.

As for Wang Yuan, Zhou Zhitao asked him to put down his young master's attitude and always remember that he is a military intelligence agent. Zhou also mentioned that Wang Yuan likes Lin Qiuyan and warned him to bear the consequences of a romantic relationship between them. Wang Yuan said he understood.

Lin Qiuyan finally finished her training and her thoughts drifted to the past days she spent with Zhang Zimo. She didn't know his current situation or what her future held, so she kept all her worries to herself. When Zhou Zhitao saw Lin Qiuyan, he returned the pocket watch that belonged to Lin Qixuan when he was killed and advised her to live well.

The Wang puppet government was established, and the general manager of the Shanghai Dahe Trading Company, Gui Tian Ci Lang, ordered the Scorpion Beauty Plan to be launched. The plan aimed to destroy the Nationalist government's economy by counterfeiting currency and to establish the East Asian Reserve Bank. Qing Mu Yi Lang and Qiao Benhong, the manager of Dahua Trading Company, had dinner together, and Qing accidentally revealed the details of the Scorpion Beauty Plan, making Qiao suspicious.

Lin Qiuyan and Wang Yuan came to find Si Duo Ye Mei. For safety reasons, they did not contact Si Duo Ye Mei immediately. Instead, they stayed in an inn across from their residence to observe the situation and decided to meet Si Duo Ye Mei at night. Xiao Wan Zi and two others closely observed Lin Qiuyan and Wang Yuan as they checked into the inn. At night, they saw Lin Qiuyan and Wang Yuan go to Si Duo Ye Mei's residence and followed them. Lin Qiuyan and Wang Yuan sneaked into the villa only to find that Si Duo Ye Mei had already been killed. They were also surrounded by Du Bian Tai Lang and his men. It turned out that the Japanese had already infiltrated Si Duo Ye Mei's residence, killed Si Duo Ye Mei, and set a trap to capture those who were meeting with Si Duo Ye Mei. Lin Qiuyan relied on her intuition to avoid the Japanese's knives but was accidentally injured. After Lin Qiuyan and Wang Yuan fought their way out of the encirclement, Wang Yuan fired a gun to distract the enemy and allow Lin Qiuyan to escape safely. All of this was witnessed by Xiao Wan Zi, Shou Hou, and Pang Zi.

Zhou Zhitao decided to call Chongqing to request to go to Shanghai, and asked Shao Zhiwei to call Lin Qiuyan to inform her of the general speculation of the Scorpion Beauty Plan and to tell Lin Qiuyan and others not to act without authorization. Lin Qiuyan went to the Stoughton Bookstore to meet A Shan and sent a secret message that Zhou Zhitao had returned safely. Lin Qiuyan and Wang Yuan speculated that the Four Wild Berries died due to internal problems, and estimated that there was a traitor, otherwise the Four Wild Berries would not have been discovered so easily by the Japanese. Through Zhou Zhitao, the two also learned some information about the Scorpion Beauty Plan. Lin Qiuyan decided to buy some food first before making a decision, and Wang Yuan warned her to be careful. Xiao Wan Zi, Pang Zi, and Shou Hou went to a restaurant with the counterfeit money they picked up from the Four Wild Berries, and were discovered by Lin Qiuyan who came to buy things. Xiao Wan Zi showed off the counterfeit money to the shopkeeper, but the shopkeeper recognized it as fake and refused to accept it. Xiao Wan Zi was confused and thought that Shanghai no longer used legal tender, and left in frustration and anger.

Chen Fuming realized that this young man had extraordinary insights. When they talked about finance, Zhang Zimo's unique insights on the economy greatly impressed Chen Fuming. In front of everyone, Chen Fuming praised Zhang Zimo and even said he would recommend him to the mayor. Zhang Zimo was very happy. Chen Fuming asked about Zhang Zimo's education and found out that he graduated from Fudan University and then studied in Munich, which made Chen Fuming like him even more. Lin Zi told Song Yikun that Zhang Zimo performed well at the party and there should be no problem entering the next stage of the Scorpion Beauty Plan. Song Yikun was happy. Lin Zi reported that someone had reported that they found a woman on the wanted list in the concession area a few days ago, but they did not catch her. Song Yikun believed that if Lin Qiuyan was trained, she should not be so easy to catch. But that also made it harder to find her. Xiao Wan Zi followed and monitored Qing Mu Yi Lang, Jing Shang, Qiao Benhong, and others and found that they went to a Japanese restaurant to drink. Lin Qiuyan went to the warehouse to find Xiao Wan Zi and the other three, but found that they were not there, so she left.

Lin Qiuyan used torture on Jing Shang, and Xiao Wan Zi and two others outside listened in fear. Jing Shang fainted, and Xiao Wan Zi and the others looked at his miserable appearance, feeling even more in awe of Lin Qiuyan. Lin Qiuyan asked the three to take care of Jing Shang and returned alone to report the situation to Zhou Zhitao at the liaison office. At Zhou Zhitao's base, everyone was waiting anxiously. Wang Yuan couldn't hold back his worry for Lin Qiuyan, but Shao Zhiwei told him to calm down. Just then, Lin Qiuyan returned and Zhou Zhitao asked her about the situation. Lin Qiuyan told Zhou Zhitao that she had already captured Jing Shang. Zhang Zimo left Dahe Foreign Company, and Mu Zhai asked Qiao Benhong to drive Zhang Zimo. Qiao Benhong deliberately revealed to Zhang Zimo that Mu Zhai was a Japanese general, in order to observe Zhang Zimo's reaction. Zhang Zimo responded cleverly. Lin Qiuyan reported to Zhou Zhitao about the kidnapping of Jing Shang. Zhou Zhitao thought that Lin Qiuyan's actions were very reckless. Lin Qiuyan had only requested to contact Jing Shang, not to kidnap him. This would only alert the enemy. Lin Qiuyan listened to Zhou Zhitao's advice.

Lin Qiuyan and Zhou Zhitao analyzed the current situation. Lin Qiuyan was troubled by the secret code incident and asked Zhou Zhitao for time to think. Qiao Benhong has been targeted by Japanese agents and his movements are being monitored. Lin Qiuyan suggested to Zhou Zhitao to contact Qiao Benhong and find out the details of the Scorpion Beauty Plan. Zhou Zhitao did not give a clear response and instructed Lin Qiuyan to keep an eye on Xiao Wan Zi and others and wait for further orders. Jing Shang was kidnapped and Song Yikun believed that only the Military Intelligence Bureau would have the capability and motive to do so. Lin Zi thought that Lin Qiuyan might be a member of a special group in the Military Intelligence Bureau in Shanghai. Lin Zi was worried about how to approach her given their different political affiliations. Song Yikun remembered that Lin Qiuyan had been observed and tested in the past and had a clear stance. If it weren't for her family's troubles, she would have been our comrade like Zhang Zimo a long time ago.
