Gu Yizhong received an anonymous note in the ward. The content asked him to join the No. 90 agent organization so that he could find the traitor. So Gu Yizhong started to have a psychological struggle. He knew what it would mean once he joined No. 90, but he had no choice but to execute the order now. His father came to pick him up from the hospital. He sent the housekeeper away, talked to his father alone, and told his decision to join No. 90. As expected, his father was furious. Originally, he wanted to send his son away, because only in this way could his son be clean. Live innocently. Unexpectedly, Gu Yizhong had the idea of becoming a traitor, which made the Gu family bear the reputation of being disloyal and unjust.
Gu Yizhong made up his mind that even if he was misunderstood by his father, he would still carry out the tasks assigned to him by the organization. Jin Jiang hurriedly walked into Zhou Zhifei's office and reported nervously: "Director Zhou, Gu Yizhong has arrived. He claimed that he was the No. 8 cell who infiltrated the Communist Party. Kondo Masao personally interrogated him and asked him why he joined No. 90. Gu Yizhong spoke frankly, saying that because of the New Fourth Army's pursuit, he had no choice but to join us in order to protect himself." After hearing this, Zhou Zhifei frowned and fell into thought.
After hearing the news, Zhou Zhifei rushed to Kondo Masao and learned that Gu Yizhong's surrender had been accepted. He hurriedly pointed out that Gu Yizhong was pretending to surrender. However, Kondo Masao smiled and said that Gu Yizhong was to them just like Zhou Zhifei's son Youfei, both of whom contributed to the common prosperity of Greater East Asia. After saying this, Kondo also handed over a letter from Youfei, which made Zhou Zhifei feel uneasy.
After Zhou Zhifei left, Kondo Masao asked Huang Xinzhai his opinion on the authenticity of Gu Yizhong's surrender. Huang Xinzhai's smooth words did not clearly state his position, but also subtly complimented Kondo. In the end, Kondo revealed the mystery and said that Gu Yizhong was actually faking surrender, and the reason why he accepted it was actually to target Gu Xixing. Kondo said frankly that only by allowing Gu Xixing to secure his position as Wuxian could Suzhou truly submit to Japan. If Gu Xixing persists, the lives of his father and son will be in danger, and Kondo will do whatever it takes to achieve his goal.
Gu Yizhong decided to return home to pack some necessities, but unexpectedly encountered Quan Shui's warning to Hai Mo, saying that if she really married Gu Yizhong, she might not be able to escape the stigma of being a "Han Jian". However, Haimo knew Gu Yizhong's character well and firmly believed that there must be unspeakable difficulties behind his actions. When she saw Gu Yizhong's busy figure, she couldn't help but stepped forward to help, and the two of them sorted the items in tacit understanding. When everything was ready, Haimo tried to lift a box of heavy objects, but Gu Yizhong gently stopped her, and sternly warned her that Gu Yuan was no longer a safe place, urging her to return to her hometown for refuge as soon as possible.
Gu Yizhong slowly walked towards his father's residence with a heavy box in his hand. He knew that his father was still furious, so he could only bow respectfully through the door, then turned around and left silently, his heart filled with guilt and helplessness towards his father.
Later, Huang Xinzhai led Gu Yizhong into the agent's lounge at Station 90. The atmosphere here was solemn, and an agent named Gao Hu was busy packing his luggage. Huang Xinzhai lowered his voice and revealed a secret to Gu Yizhong: Gao Hu appeared to be here to protect him, but in fact he was spying on him secretly. This news gave Gu Yi mixed emotions, but he quickly adjusted his emotions and prepared to face the next challenge.
In the days that followed, Gu Yizhong began rigorous spy training. In order to test his will, Zhou Zhifei even deliberately arranged for someone to beat him brutally in an attempt to force him to give up. But Gu Yizhong gritted his teeth and persevered with his firm belief and tenacious perseverance. He knew that this test was not only a physical torture, but also a test of his will and loyalty. And he must prove himself. For the greater goal and the belief in his heart, he must continue to move forward.
