Ke Jingping tells Shi Changsheng that he misunderstood him, and that he just wanted to defend Changsha. Shi Changsheng tells him that as a soldier, he must obey orders as his bounden duty. He says that Xue’s defiance of orders is disloyalty to discipline, to the party and the country, and to the leader, and he asks Ke Jingping to think about it carefully. Shi Changsheng asks him how the matter with his eighth brother is going, and Ke Jingping says there has been no progress. Shi Changsheng also says that the director is very dissatisfied with his performance these past few days, and that Yun Hongshen is holding onto the codebook and Ke Jingping is letting him do whatever he wants. There was Wen Yeming, and now there is Yun Hongshen, and he says that Ke Jingping has spoiled them all.
Ke Jingping says that everything he does is for the benefit of the party and the country, and Shi Changsheng says that there is no doubt about that. Shi Changsheng says that Ke Jingping must understand who the biggest enemy of the party and the country is besides the Japanese, and that is the Communist Party. Wen Yeming found out that Milan was also involved in this Xingdong operation, and she was also in a leadership role. She knows that Milan’s position in the intelligence network is not low, and she should be on par with Zong Fang. What makes Wen Yeming even more terrified is that Milan participated in the entire operation, but she was not exposed and even escaped safely. Wen Yeming knows that Milan must be more difficult to deal with than she imagined, and she feels that she must tell Yun Hongshen about this.
Wen Yeming goes to find Yun Hongshen but finds that he is not in the office, and his subordinates tell Wen Yeming that Yun Hongshen has gone out. Shi Changsheng asks Ke Jingping to escort Yun Hongshen back to Chongqing no matter what, and confirm his suspicion of being a Communist. Ke Jingping says that he obeys orders, and he asks where Yang Ziming is. Shi Changsheng says that this is the second task assigned to him by the director. The first is to secretly investigate Yang Ziming without alarming him, and the second is to have solid evidence. Ke Jingping receives two photos. In the photos, Yun Hongshen is in a phone booth. His subordinates tell him that it may be Yun Hongshen who pretended to be Milan and made the call to frame Ling Han. Wen Yeming is thinking about where Yun Hongshen has gone, and Ke Jingping calls her to his office.
Ke Jingping tells her that Yun Hongshen is a Communist. Wen Yeming asks him if it was Ling Han who reported him, and if he wants to bite Yun Hongshen back. Ke Jingping says that now they have to catch Yun Hongshen, so that they can involve Yang Ziming behind him. Wen Yeming says that it is time for internal strife, and she feels that if they are not led by a good leader, do they still need to be loyal? Ke Jingping asks her if she knows what she is talking about, and he asks Wen Yeming if she has forgotten her original intention of joining the military. Wen Yeming finally obeyed Ke Jingping’s order, and Ling Han also continued to put pressure on Ke Jingping, hoping that he could deal with Yun Hongshen as soon as possible.
Ke Jingping calls Zhu He to arrest Yun Hongshen, and he tells Ling Han to leave room for himself. Wen Yeming can’t find Yun Hongshen and she is very anxious. She comes to the archives and takes away the information about Ling Han. Wen Yeming hopes that she can help Yun Hongshen clear his name. Yang Ziming comes to the river and asks Lao Hei if anyone has been here today, and Lao Hei says no. Yun Hongqi, who lives here, saw a person and asked Lao Hei if it was Yang Ziming. Lao Hei said no, Yun Hongqi said that he grew up watching Yang Ziming, even if he disguised himself, he would not be mistaken. Yun Hongqi knows that Yang Ziming must have come here in person because something happened at home, so he and Xiao Dao quickly prepare to go home.
Yang Ziming tells Secretary Wu that the people from the military command must have taken action, so he has to give himself up, only in this way can he divert their attention. Yang Ziming told Secretary Wu that in the future he would be the liaison to replace him and be responsible for connecting with Yun Hongshen. Then Yang Ziming returned home and arranged for someone to go to Shanghai to transport the batch of gold. Yang Ziming knows that many soldiers on the front line died due to underdeveloped medical care, so he wants to use the money to buy Western medical equipment and medicines. Yun Hongshen secretly met with Wen Yeming, and Wen Yeming told him about the photo. Yun Hongshen knew that he had been framed by Ling Han. Ling Han heard that Ke Jingping was going to interrogate Jing Yu, so he killed Jing Yu. Yun Hongqi was very angry when he found out, and called the military command to ask them about Yun Hongshen.
