Episode 7 recap: Lao Zhao is successfully rescued.

At the inauguration banquet of Ma Shi Zhang, Tian Liu crossed paths with Chen Ke Hai. Fang Li happened to turn around and noticed that Tian Liu looked exactly like Shen Qiu Ping. She approached Fang Li and introduced herself. Lao Zhao contracted cutaneous anthrax at the Army Hospital, an extremely contagious disease that required immediate transfer to another hospital. Chen Ke Hai didn't dare to transfer him without seeking approval from superiors. Lao Zhao was rescued by someone, and Fang Li initiated an internal investigation, suspecting the presence of a Communist Party spy.

During the celebration of Ma Shi Zhang's appointment, Fang Li's subordinates suggested that he go on stage and say a few words. Ma Shi Zhang's expression revealed a hint of displeasure. Fang Li stated that he didn't possess the greatness that Ma Shi Zhang had praised earlier. His ambitions were not as lofty, and intentionally mispronounced words on stage, implying a significant criticism of Ma Shi Zhang. During the banquet, Fang Li intentionally introduced Chen Ke Hai, and Ma Shi Zhang deliberately spilled wine on Fang Li, hypocritically chastising him to study hard and not become arrogant and conceited due to a small accomplishment. When Lao Zhao was discovered to be infected with anthrax at the hospital, Fang Li was promptly notified. He instructed Chen Ke Hai to handle the situation at the hospital, and as Chen Ke Hai went to deal with it, he brushed past Shen Qiu Ping.

Fang Li inadvertently noticed a person who looked exactly like Shen Qiu Ping and Tian Liu generously introduced herself. Before he could react, she had already left. Fang Li recalled the time when he couldn't bear to see Shen Qiu Ping being insulted by the individuals from Group 76, so he had no choice but to shoot and kill her. Chen Ke Hai arrived at the hospital, and the doctor informed him that the patient had contracted cutaneous anthrax, which required immediate transfer due to its high level of contagiousness. Chen Ke Hai questioned if the security officer's choice of a small car was what led to Lao Zhao's infection. Due to his weak physical condition and low immune system, he was susceptible to infection. Chen Bin stayed behind to guard Lao Zhao. Chen Ke Hai fell asleep while holding Shen Qiu Ping's pocket watch, fully aware that Fang Li suspected him. Therefore, he left the hospital and returned to his office to rest and avoid suspicion.
The students took to the streets again to protest, and the police began to intervene and use force against them. Lao Zhao was rescued from Chen Bin's surveillance by someone and discovered a ventilation opening on the roof. Lao Zhao was saved by Lao Duan, a comrade who had infiltrated the hospital, but they quickly evacuated after rescuing him. The plan to spread anthrax was also Chen Ke Hai's idea, and Lao Zhao praised him for being young and promising. Fang Li regretted not heeding Chen Ke Hai's advice and insisted on transferring to the Japanese Army Hospital, which led to a mistake. As the students helped each other leave the scene of the protest, Fang Li witnessed this and became even more determined to fight for his beliefs.

Lao Jin discovered that Tian Liu's background had nothing to do with Shen Qiuping. Fang Li discussed why the Communist Party went to great lengths to save someone who was almost dead. He suspected the presence of a mole, which allowed Lao Zhao to be smoothly taken away. Chen Bin severed one of his subordinate's fingers and recalled that Lao Zhao had fallen onto a garbage truck. Since then, it seemed like he had been infected. Chen Bin urgently searched for the garbage truck personnel.

Xing Han Zhu arrived at a jeweler's house, and the jeweler didn't understand the purpose of his visit. Xing Han Zhu directly revealed their true identities as Military Statistics Special Agents. The Japanese received a tip and found anti-Japanese propaganda leaflets being printed in the vicinity. Fang Li and his team searched door-to-door in the area, but the Japanese cruelly killed Chinese people instead of conducting searches. Xing Han Zhu, without obtaining intelligence, directly killed the Military Statistics Special Agent. Meanwhile, the Japanese found numerous girls in the cellar. They were brought out, and among them, Luo Bing was dragged by Yamada into a secluded alley, intending to assault her. Chen Ke Hai used a shard to kill him directly. The Japanese were searching for Captain Yamada, and Chen Ke Hai deliberately put on a Japanese military uniform and pretended to be intimate with Luo Bing to evade suspicion. Luo Bing hid a shard in her shoe. This scene reminded Chen Ke Hai of Shen Qiuping, and he handed her his business card, suggesting that she could seek help from him if she encountered difficulties. However, she rejected his offer of assistance, stating that she would not associate with collaborators, and then limped away.

Fang Li had Li Tang handle Yamada's body, and he disposed of the body by throwing it into the Huangpu River. Chen Ke Hai was walking home when he was held at gunpoint by Qiao San Min. Chen Shu discovered Chen Ke Hai's situation and promptly informed Fang Li. Chen Ke Hai was tied up in a warehouse, and Qiao San Min had experienced two years of suffering, all thanks to Fang Li. They had bound Chen Ke Hai to lure Fang Li to come. At that moment, Fang Li was in Dashi World with a woman, deeply engaged in their conversation. Upon learning that Chen Ke Hai had been captured, he immediately went to the dock warehouse to rescue him. Years ago, Qiao San Min and Fang Li escaped to an alley while carrying the unconscious Shen Qiuping. They were pursued by enemies, and in order to save himself, Fang Li directly pushed Qiao San Min out, sacrificing him. Qiao San Min was also a man of loyalty and emotions, but he couldn't accept this type of sacrifice as bait. Moreover, he never expected that Fang Li would join the Japanese and become a collaborator, and Shen Qiuping also sacrificed her life because of it.
