Enlighten Your Life – Zheng Yecheng, Liu Ruilin

A group of Yugoslavian nuclear experts, led by Leman, were invited to visit the Qin Chang nuclear power plant for inspection. They pointed out numerous problems at the construction site and questioned China's ability to independently build nuclear power plants, demanding an immediate halt to the construction. Lin Tiancheng was anxious and had no choice but to seek help from Ye Jiaming. The two of them, along with welding engineer Meng Zhiyuan, intercepted the expert group on their way back using Meng's small truck. Ye Jiaming boldly proposed a long-considered rectification plan, which impressed Leman and he promised to report the situation truthfully to relevant government departments and suggested giving time for rectification. Dean Qin of the Nuclear Research Institute called Ye Jiaming, Lin Tiancheng, and Meng Zhiyuan to his office to inquire about the situation, while the head of the administrative management department, Ding Li, sternly criticized the three for their rash behavior. At this time, Leman called and asked Ye Jiaming to calculate a plan with him, and the hope for the Qin Chang nuclear power plant was reignited.

Ye Jiaming, Lin Tiancheng, and Meng Zhiyuan became friends and were known as the "Qinchang Three Musketeers". Their families also became close. Expert Leman invited Qinchang Nuclear Power to send people to study at a nuclear power plant in Yugoslavia, and Lin Tiancheng was among them. This worried him because he had lost his wife and didn't know who would take care of his son, Lin Qi, while he was away. In desperation, Lin Tiancheng turned to Ye Jiaming and asked Lu Yunzheng to help take care of Lin Qi. On the other hand, Meng Zhiyuan's wife, Zhang Lan, decided to take the rare opportunity to study medicine in the United States. Since Meng Zhiyuan was busy with work, Ye Jiaming took on the task of taking care of their daughter, Meng Xiaowei. Thus, Ye Jiaming and Lu Yunzheng became parents to three children. After six months of renovation, the Qinchang Nuclear Power Plant finally entered the modern construction phase. The Leman expert group came to inspect again and praised the construction site, saying that the Qinchang Nuclear Power Plant would become a nuclear power plant that meets international standards.

Meng Zhiyuan has been suffering from long-term physical discomfort and was diagnosed with advanced pulmonary heart disease after going to the hospital for a check-up. Lu Yunzheng took out all the savings at home and tried her best to help Meng Zhiyuan treat his illness, but Ye Jiaming told her that the doctor diagnosed that Meng Zhiyuan only had one month left at most. To keep it from Xiaowei, Meng Zhiyuan said he was going on a business trip to a faraway place, and Xiaowei believed him. Ye Jiaming accompanied Meng Zhiyuan at the hospital bed, feeling deeply saddened. Meng Zhiyuan said that not being able to see the completion of a nuclear power plant built entirely by China was the biggest regret of his life, which made Ye Jiaming feel choked up. Professor Wen, who has long supported the introduction and had a significant influence in the nuclear power industry, heard that Yue Changshan was conducting independent core research and brought his student Xu Jichuan to Zero Point. Xu Jichuan looked at the confirmed 177 core plan and said he supported 193 more. At this time, Ye Jiaming returned from visiting Meng Zhiyuan and saw that the direction they were focusing on had been changed, leading to a heated debate with Xu Jichuan. To ease the argument, Yue Changshan proposed using data to speak and let all the key personnel in the business vote.

Zhang Lan rushed back from the United States to see Meng Zhiyuan's weakened state, feeling a mix of emotions. Meanwhile, Ye Jiaming, faced with pressure from Xu Jichuan and Meng's dying wish, became obsessed with presenting the 177-core plan. As the new round of voting for the core plan began, the support for the 193 plan was already well over half. However, just as the dust was settling, Ye Jiaming rushed in and discovered that by optimizing the procurement plan and replacing imported equipment, the economic viability of the 177 plan could be greatly enhanced. The researchers present enthusiastically discussed this, and ultimately the 177-core plan won by an overwhelming majority. As sympathetic opponents, Ye Jiaming and Xu Jichuan had a deep conversation and shook hands, determined to do their best for China's nuclear power industry.

The long-awaited singing competition finally opened in the auditorium, and Meng Xiaowei was there. Meng Zhiyuan arrived late in a wheelchair. At the moment when everyone was moved, Ding Li led a group of security personnel to break in and announced an immediate investigation into Lin Tiancheng and Ye Jiaming. Lin Tiancheng finally exploded with his long-held emotions and expressed his desire to leave Qin Chang and go abroad. He had witnessed the humiliation of the country's lack of scientific research strength and the absence of a truly independent nuclear power brand through negotiations abroad. He wanted to switch to sales and sell foreign technology and products to China at the most economical price. In the low atmosphere, Meng Zhiyuan closed his eyes forever. Lin Qi followed his father Lin Tiancheng to the United States, and Meng Xiaowei left the nuclear power institute with her mother Zhang Lan. The three families who were once as close as family were scattered all over the world.

Time flies, and in the blink of an eye, Lin Qi, who has grown up, has become an operator at the Qinchang Nuclear Power Plant in 2009. While dealing with a crisis, he catches the eye of the old man from the thermal department, Zhong Dagong. However, he already has his heart set on becoming an operator after passing the operator's exam. At the Qinchang Nuclear Power Plant simulation training center, Lin Qi meets Meng Xiaowei, who has the same dream of becoming an operator after thirteen years apart. He feels guilty for the unintentional harm he caused Xiaowei in their childhood and tries to mend their relationship, but accidentally breaks the "Little Golden Man" left by Meng Zhiyuan for Xiaowei. Ye Qichen has also graduated from the United States and specifically applied for the position of assistant chief engineer at the Nuclear Research Institute, eager to work alongside his father, Ye Jiaming. The three of them return to Qinchang separately.

After reuniting, Lin Qi was constantly met with cold looks from Meng Xiaowei. To make up for his mistake, Lin Qi tried everything to make Meng Xiaowei happy, but it had little effect. Ye Qichen's return to China was also not going well. He was surprised to see that the chief designer he had been waiting for was replaced by Xu Jichuan, his own father. Dean Yue took him to the exhibition hall and explained Ye Jiaming's decision to him. Ye Qichen was greatly shocked and began to understand his father's decision. Ye Qichen became Xu Jichuan's assistant at the nuclear research institute. Ye Jiaming specifically instructed Xu Jichuan to train Ye Qichen well from the basics, as his life had been too smooth in the past 20 years and he was prone to overconfidence. Xu Jichuan agreed and assigned a group task to Ye Qichen. Ye Qichen quickly completed the data calculation alone, but Xu Jichuan pointed out that he lacked team spirit, which made him feel a little discouraged.

Lin Qi proposed to form a study group and asked Ye Qichen to be the teacher. Meng Xiaowei reluctantly agreed. After a heart-to-heart chat, the tension between the three gradually dissipated, and Lin Qi became more determined to take care of Xiaowei and Qichen. Zhong Dagong found Lin Qi and believed that he was not suitable to be a manipulator. He invited him to work in the nuclear research institute, but Lin Qi refused and said that he only wanted to be a manipulator. Zhong Dagong tried his best, but to no avail. He even brought in Ye Jiaming, but it still didn't work. However, Lin Qi's performance in the simulator training repeatedly confirmed Zhong Dagong's judgment. Lin Qi often received criticism from instructor Li Hailin for not following the rules, while Xiaowei was always an excellent student, which Lin Qi admired. In the family building, the study group of Lin Qi, Ye Qichen, and Meng Xiaowei was officially formed, and the three seemed to return to the happy time of living together when they were young.

Ye Qichen went to the Materials Institute to confront his father about his work issues. Ye Jiaming tried to persuade Ye Qichen to be humble and endure hardships in order to grow, but Ye Qichen refused to listen and had a big argument with his father before leaving. Lin Qi and Meng Xiaowei went to visit Ye Jiaming at the Materials Institute and saw that he had a high blood pressure attack due to being angry with Ye Qichen's behavior. On the way back, Meng Xiaowei was attracted by a "not for sale" guitar in a shop window, and Lin Qi secretly remembered it. Ye Qichen went to a bar to drown his sorrows, and when he was drunk, Lin Qi came to take him back to the dormitory. The next day, Ye Qichen applied to join the pile research group, but Xu Jichuan did not approve and instead suggested that Ye Qichen join the double-layer safety shell research group, which made Ye Qichen even more confused.

Lu Yunzheng patiently persuaded Ye Jiaming that sometimes, only as a father, he could help Ye Qichen overcome the obstacles on his path to growth. In order to untie the knot between father and son, Lu Yunzheng specially invited Lin Qi and Meng Xiaowei to come to their home to make dumplings together. The family finally gathered together happily. Lu Yunzheng created an opportunity for Ye Jiaming and Ye Qichen to be alone. Ye Qichen revealed to his father that he wanted to resign, which shocked Ye Jiaming. After resolving the work issue, Ye Jiaming came to Qichen's office building with a guilty conscience, and the father and son had a heart-to-heart talk. Ye Jiaming talked about his work experience over the years, blaming himself for not fulfilling his responsibility as a good father due to work reasons, and encouraged Qichen not to give up his ideals. The knot between father and son was completely untied
