Episode 6 recap: Wang Qiu Shui suspects Ou Xiao An's identity.

Wen Yi Shan repeats what Ou Xiao An said, believing there is a mole at the Chongqing station. Wei Qing Ming believes the words of a traitor cannot be trusted, and states that everything is under control. He is about to interrogate the former Japanese army bioweapons expert, Ando. Feng Yu Nian orders Jiang Zhan Xin to guard the decryption department 24/7 and find the exact location of the gas bomb deployment.

Qin Mo Qing goes to a cheongsam shop, pretending to buy a cheongsam to report the situation to Wang Qiu Shui. She gives Wang Qiu Shui Ou Xiao An's banner, believing it is the breakthrough to find 810. Wang Qiu Shui learns that Ou Xiao An has amnesia and suspects she is one of them.

Years ago, Lou Ming Yuan applied to the organization to be recruited, but was later captured and sacrificed, the details unknown. Qin Mo Qing believes that Wen Xuan Min and Ou Xiao An were captured at the same time, and suspects Wen Xuan Min is still alive. Qin Mo Qing has always felt guilty about the past events, and is burdened after Wen Xuan Min's capture.

Her brother is preparing to move the family to Chongqing, but he disagrees with Qin Mo Qing attending a red culture lecture, leading to an argument. Qin Mo Qing takes the opportunity to steal one of his travel passes while he is on the phone.

Qin Mo Qing uses the travel pass to go out, but is stopped by Zeng Ji Wu, who asks about her relationship with Qin Ji Ru, learning they are siblings. Qin Mo Qing says she is going to visit the injured driver, and Zeng Ji Wu, who previously had a poor relationship with Qin Ji Ru, has his men openly follow Qin Mo Qing.

Qin Mo Qing takes the opportunity of buying pastries to pass the travel pass to Old Li, successfully evading Zeng Ji Wu's investigation. However, Zeng Ji Wu still suspects her and has his subordinates check on the driver, confirming he has been ill recently. Wang Qiu Shui and the others are discussing how to evacuate Shanghai as soon as possible, moving the radio station and supplies.

Her biggest concern is whether the Miltary Statistics Bureau can successfully complete the Sundial operation and retrieve the Falling Cherry blossom plan, not letting the Japanese experiment with bioweapons again. Old Li delivers the travel pass to Wang Qiu Shui, resolving her current predicament.

Afterward, Wang Qiu Shui was satisfied with Qin Mo Qing's performance and assigned her a new task, hoping that through her relationship with Qin Ji Ru, she could infiltrate the Military Statistics Bureau (Gestapo), participate in the Gestapo's training class, and be given the code name "Wild Grass". The two would maintain direct contact, and she would be formally notified that she was a member of the Communist Party, and she would take the oath immediately.

After stabilizing in the Gestapo, Qin Mo Qing applied to enter Burma independently as a military doctor. Thinking about this, Qin Mo Qing requested that the organization continue to let her follow up on this line. Wang Qiu Shui assigned her a new task, asking her to quickly confirm Ou Xiao An's amnesia, find clues about 810, and provide help to Ou Xiao An, but without exposing her own identity. He also asked her to lead Gestapo personnel to deal with the three Japanese individuals in Shapingba.

Qin Mo Qing obtained the clues and went to the designated location, which was a restaurant run by the Japanese army. She promptly resolved the situation there. Feng Jing Xian was walking home from school, distracted. Li Shao Tang came to pick her up, promising that after the war was over, he would resign from his Gestapo position and come to her school to teach natural science classes and accompany her.

When they returned home, Feng Jing Xian suddenly wanted to talk about past stories, but accidentally mentioned Ou Xiao An, expressing disappointment that Ou Xiao An had become a traitor. Li Shao Tang said he would not deceive Feng Jing Xian, seeing that she was still thinking about Ou Xiao An, and Feng Jing Xian just wished for him to stay alive.

Li Shao Tang recalled that in 1941, Ou Xiao An had accompanied him to the train station and instructed him to be sure to deliver the Falling Cherry Blossom plan to Wen Yi Shan in Chongqing. A Gestapo agent had been planted on the train to escort Li Shao Tang and remind him not to make eye contact with the Japanese soldiers, and to remain calm.

After Li Shao Tang boarded the train, there was a Japanese military inspection. Fearing the contents of the box would be discovered, he deliberately placed the box on the floor. The Japanese soldier, seeing his nervous demeanor, demanded to search his luggage. The Gestapo agent, sensing the situation was deteriorating, intentionally created a disturbance to divert the Japanese soldier's attention, but Li Shao Tang, frightened, fled with the Falling Cherry Blossom plan, and was pursued by the Japanese.

When Feng Yu Nian returned home, she saw Aunt Wu preparing invitations and asked her to temporarily suspend the distribution. Feng Jing Xian brought Li Shao Tang back home, where they found Feng Yu Nian shouting. Feng Yu Nian sent Feng Jing Xian away, saying she had something to discuss privately with Li Shao Tang.
