The autumn of 1946 was destined to be an eventful one. The headquarters of the Security Bureau moved back to Nanjing, and the spies who stayed in Chongqing became more and more rampant. The Yan Secrecy Bureau sent a large number of spies to Yan'an, and Chen Yuting quietly told Zhao Yunfei the news. In order to eliminate the spies in Yan'an, the organization passed the test on Li Jinping and sent her to follow Linda to clean up the spies. These secret agents lurking in Yan'an have been targeted by Yan'an. Linda returned to Yan'an to meet Li Jinping, who discovered many spies working in Yan'an.
Ma Wu's wife and brother-in-law went around looking for gifts from Cao Shun and Zhuang Meijiao to clear up the relationship, but Cao Shun didn't accept it, but asked him to share it with his brothers. Zhuang Meijiao was even more stubborn, and the siblings were anxious about the issue of pensions. Zhao Yunfei and Chen Yuting sat by the river and chatted. There were some things that Zhao Yunfei couldn't forget when he saw them. He told Chen Yuting the story of his childhood. Now that the war has disappeared, Zhao Yunfei doesn't understand the meaning of continuing to do intelligence work.
Yan'an. Linda and Li Jinping are trying their best to hunt down the spies, and they are experienced and efficient. Aunt Wu went to the grocery store to buy something again, and said that there were guests at home, and Chen Yan and Zhao Yunfei went to the house to drink. Sister-in-law Wu has been followed by Zhuang Meijiao, and the convenience store has been under surveillance. Zhuang Meijiao implemented a district blackout to reduce the area. Wang Zhenchuan and Xie Xiaoya realized that they had been suspected. The spies broke into the grocery store in the middle of the night to search, and left after making a mess. Wang Zhenchuan could only order other information to be sent out through other channels. Linda and Li Jinping quickly locked on the spies. Cao Shun was very dissatisfied with Zhuang Meijiao for letting his brothers patrol day and night, but Zhuang Meijiao directly told him to leave, which shocked the whole office.
During the war, the living expenses and pensions that the military dependents depended on for their survival were cut off, which caused great dissatisfaction among them. Ma Wu's wife and brother-in-law were even more worried, so they could only tighten their tails and behave. Chen Yuting is now very busy with the pension. In addition, she is also busy finding out the truth about the death of her father Chen Huai'en. Zhao Yunfei also wants to help.
Yan'an can't prove that Ji Min has a relationship with the enemy for the time being, but they still haven't let down their vigilance. Li Jinping found a familiar face. Although he can't remember who he is, he confirms that he must be a member of the military commander. Zhao Yunfei went to the reference room again, wanting to investigate some information about Chen Huai'en, but was almost discovered. Zhao Yunfei checked Li Zhuoqun's two lists, and remembered clearly that Chen Yuting kept looking for Li Zhuoqun's children, and he might know something. Chen Yuting and Zhao Yunfei found Li Zhuoqun's concubine, but she said she didn't know anything, otherwise she wouldn't have been in the skin business after Li Zhuoqun's death.
Linda and Li Jinping captured the spies, but missed the fish that slipped through the net hidden in the crowd. The secret agents lurking in Yan'an are very cautious, and often use a movement and a look to convey information.
