Wen Yeming instructs Chen Dongping to find Milan’s former classmates and obtain her photos for comparison to confirm her identity. She emphasizes the need for a thorough investigation, saying the more detailed, the better. Chen Dongping asks if she suspects Milan is the murderer. Wen Yeming replies that the woman has always made her uneasy, and this incident has strengthened her belief that Milan is definitely more than just a nurse. Wen Yeming orders Chen Dongping to locate the rickshaw Milan took and bring the driver in for questioning, emphasizing that no one should contact the driver before she sees him.
Zhu He informs Ke Jingping about the results of his investigation into Li Liang, leading them to believe the mole is still within their station. Ke Jingping praises Zhu He’s intelligence and contrasts his approach with Ling Han’s impulsiveness. He asks Zhu He if he thinks Ling Han is the mole. Zhu He acknowledges Ling Han’s aggressive work style but doesn’t definitively label him as the mole. He suggests that the friction between them could be a tactic employed by the mole. Ke Jingping commends Zhu He for his broad-mindedness. Zhu He then asks Ke Jingping if they should utilize Yun Hongshen’s informant in Shanghai. This reminds Ke Jingping of Wen Yeming’s suggestion to stir up the situation and create confusion, noting that the mole would undoubtedly be interested in Yun Hongshen’s informant. Ke Jingping thanks Zhu He for the reminder.
Jingui visits the police station again to ask Captain Tang for help in reopening Xiaoyaoju. She overhears a policeman telling Captain Tang that reopening Xiaoyaoju is impossible now, given the tragic death of Old Mrs. Yun. Even if it reopens, its reputation will be severely damaged. Jingui pleads with Captain Tang for help, but he insists he can’t do anything for her. Jingui reminds him that they are in the same boat, but Captain Tang denies any connection and leaves. Jingui then goes to Mengying, informing her about Old Mrs. Yun’s death and the military’s suspicion that she was involved. She explains that they plan to shut down Xiaoyaoju, which represents Bai Qingkui’s life’s work. Mengying tells her not to worry and promises to ask Captain Tang when he returns.
Jingui insists that Captain Tang must share the responsibility with her. Mengying agrees to help but objects to the idea of sharing responsibility, finding it outrageous. Jingui reveals that she is the real owner behind Lao Zhang Pharmacy. Mengying is shocked to learn that Jingui and the others conspired to deceive her. Jingui explains that the contract Mengying signed wasn’t for investing in the pharmacy but for investing in Xiaoyaoju. Mengying is furious that Jingui would deceive even her. Jingui justifies her actions by claiming she was using Captain Tang as a safeguard, which has now proven useful. Enraged, Mengying slaps her. Mengying then goes to the police station and asks Xiao Huang about Xiaoyaoju. Xiao Huang warns her to stay away from the matter.
Mengying realizes the gravity of the situation and fears that Captain Tang will be implicated. Milan attends Old Mrs. Yun’s funeral. Yun Hongshen, filled with anger and hostility upon seeing her, tries to confront her, but Yang Ziming stops him. He pulls Yun Hongshen aside and asks what’s going on. Yun Hongshen shows Yang Ziming the orchid handkerchief and reveals that Milan is his grandmother’s murderer. He breaks down, confessing that seeing his grandmother’s body made him doubt his own abilities to handle the mission and find Kunwu. Yang Ziming assures him that he has become a mature warrior, capable of calmness, restraint, and strategic thinking. He adds that Yun Muzhi would be proud of him and expresses his confidence in Yun Hongshen’s eventual success.
Yun Hongshen asks if he can join Yang Ziming’s party organization. Yang Ziming reveals that he already knows about Yun Hongshen’s intentions. Yun Hongshen admits he had guessed as much, and Yang Ziming welcomes him. He then brings up the issue of informing Yun Hongqi. Together, Yun Hongshen and Yang Ziming tell Yun Hongqi about Milan’s suspicious identity and the possibility that she murdered his grandmother. Yun Hongqi initially refuses to believe them, but Yun Hongshen presents the handkerchief as evidence. Consumed by hatred, Yun Hongqi wants to kill Milan, but Yun Hongshen stops him. Yun Hongshen then goes to Milan’s house and discovers her hidden handgun, confirming his suspicions about her true identity.
