Shi Changsheng tells Yun Hongshen that if he guessed correctly, Yun Hongshen detained him to ensure his safety. Yun Hongshen recalls his subordinate mentioning that Shi Changsheng seemed like an important figure. He explains to Shi Changsheng that if he had disembarked earlier, the Japanese would have identified him as a key person and targeted him to create chaos, rescuing “Mister” and protecting their secrets. Yun Hongshen points out that their plan failed, and whether it was to retrieve “Mister” or for revenge, Shi Changsheng would be the primary target for the Japanese. He emphasizes that staying on the ship is the safest option for Shi Changsheng, as they wouldn’t risk harming “Mister” unless they wanted to perish together.
Yun Hongshen reveals to Shi Changsheng that he deliberately cooperated with him to let the fake “Mister” disembark and lure the Japanese into action, allowing them to be captured. Shi Changsheng praises Yun Hongshen’s clear and effective analysis. However, he’s curious about Yun Hongshen’s identity and introduces himself. Among the cooks, one asks to use the restroom. Yun Hongshen’s team member escorts him but gets killed. It turns out this cook was also a Japanese accomplice who had dug a hole in the floor to shoot at Yun Hongshen’s group, but Yun Hongshen discovers and kills him first.
Zhu He arrives and questions Yun Hongshen’s actions. His team member explains that Yun Hongshen is upset about the death. Zhu He expresses his own displeasure and criticizes Yun Hongshen’s behavior. Shi Changsheng defends Yun Hongshen as a promising agent trained by Ke Jingping and Zhu He. Zhu He deflects the credit, attributing it all to Ke Jingping, and urges Yun Hongshen to leave with him now that it’s safe. Yun Hongshen pulls Wen Yeming aside and embraces her. She assures him she’s fine but mentions they didn’t catch Zong Fang. Yun Hongshen dismisses it. An Zhiyi and Mrs. Lin, who are still detained, observe this and comment on Yun Hongshen having a weakness.
Yun Hongshen questions them about who “Mister” is, suggesting they might both be “Mister” together. He deduces that as twin sisters, one is responsible for dispatching the list while the other handles the contact code. Mrs. Lin claims he won’t find the list without her hint. Yun Hongshen expresses his disdain for threats, especially those involving his loved ones. Mrs. Lin insists they won’t find anything, but suddenly someone shoots and kills both sisters from the ship’s ceiling.
Yun Hongshen analyzes where they might have hidden the dispatch list, considering it must be secure yet retrievable. He realizes they might be the list themselves. He notices Mrs. Lin’s green earrings, and Wen Yeming uses scissors to cut open their backs. Yun Hongshen applies the liquid from the earrings onto their backs, revealing the list. The mission is considered a success as they obtain the dispatch list. Using this list, Ke Jingping captures all the Japanese spies. They discover that Ji Fang’s fiancée is a Japanese spy radio operator and, based on her confession, identify Zong Fang as her superior. They fail to locate another person and find an empty apartment when they try to contact a provided phone number.
Due to Yun Hongshen’s treatment of Shi Changsheng, Ke Jingping issues him a disciplinary action.
Ling Han is released from prison. Ke Jingping challenges him to find evidence if he believes he was wrongly accused. Yun Hongshen contemplates Zhang Xiancheng’s dying words. Wen Yeming inquires about his sullen mood, and he attributes it to the disciplinary action. She consoles him, mentioning Shi Changsheng’s pride and Ke Jingping’s difficult position. Yun Hongshen receives a call from Jing Yu and learns that Yang Ziming has requested a meeting. Yang Ziming reveals that Zhang Xiancheng was one of their own. Yun Hongshen relays Zhang Xiancheng’s last words, leading Yang Ziming to realize there’s a problem with the “Gold Snatching Plan” which he then explains to Yun Hongshen. Aware that their identities as communists might be exposed, Yang Ziming plans to arrange Yun Hongshen’s escape. Meanwhile, Shi Changsheng also deduces Yun Hongshen’s true identity and urges Ke Jingping to arrest him immediately.
