Ling Han showed Wu Tong a photo of his fiancée. Wu Tong pleaded that she was innocent and unaware of his activities, begging Ling Han to spare her. Ling Han assured him that as long as he cooperated, he wouldn’t bother her. He then asked Wu Tong to reveal who helped Bai Qingkui transport goods on July 2nd, leaving Wu Tong deep in thought.
Ke Jingping told Wen Yeming that the Zhu He incident had angered him so much that he couldn’t sleep all night. If Zhu He and Li Liang were wrongly accused, this would become a complete scandal. Ke Jingping felt that if there was another person involved, then both he and Ling Han had been deceived, indicating that this person was extremely dangerous and cunning.
Ke Jingping considered another possibility, the most terrifying one: that this person was Ling Han. He expressed his uncertainty about who to trust within the station, feeling it was his negligence. Wen Yeming comforted him, saying that with his upright nature, he wouldn’t have imagined someone being so unscrupulous. She assured Ke Jingping that she would help investigate thoroughly.
Just as they finished their conversation, Deputy Officer Chen from the headquarters arrived. He stated he was sent by the commander to inquire about two matters. Ke Jingping acknowledged he knew what Chen wanted to ask, confirming that he was already investigating the cipher issue.
Regarding Zhu He, Ke Jingping acknowledged his relationship with the commander but insisted that no one interfere with their investigation. Deputy Officer Chen complained that this response made it difficult for him to report back, implying Ke Jingping was making things difficult for him. Ke Jingping remained firm, stating that even if the commander came himself, his answer would be the same.
Deputy Officer Chen mentioned that the commander acknowledged the difficulty in tracking down the cipher and started to suggest that if Ke Jingping couldn’t handle it… but before he could finish, Ke Jingping interrupted, asserting that if even he couldn’t find it, then others were unlikely to succeed either. At that moment, someone called for Ke Jingping, informing him that Zhu He wanted to see him. Another person reported that Ling Han had extracted information from Wu Tong.
Ke Jingping immediately ordered Wu Tong to be sent to the hospital, intending to interrogate him after he recovered. It turned out that Yun Hongshen had discovered Wu Tong’s allergy to cologne and used it to make him talk. Yun Hongshen had done this to investigate Ling Han, promising Wu Tong that if he wanted to see his fiancée, Xiao Hua, he should cooperate.
Ke Jingping then met with Zhu He, who explained why he killed Bai Qingkui. During his explanation, he mentioned Yun Hongshen. Upon hearing this, Ling Han immediately left for the evidence room. Yun Hongshen also arrived at the evidence room and discovered that the bullet casing from the gun used to kill Kawashima had been replaced.
During a meeting, Ling Han questioned Yun Hongshen about his whereabouts before the meeting. Yun Hongshen claimed he had been experiencing constipation.
Milan visited the Yun family to gauge their attitude towards her. Seeing everything was normal, she assumed Kawashima hadn’t revealed her identity. Ling Han told Wen Yeming that he suspected Yun Hongshen was the one who helped him obtain the ledger that day and also the one who kidnapped Kawashima. Wen Yeming met with Yun Hongshen, asking if he had tampered with evidence in the evidence room. Yun Hongshen explained that he did so to disrupt the mole’s scheme. When Wen Yeming further questioned if he was the one who kidnapped Kawashima, Yun Hongshen remained silent.
Ling Han led a team to investigate Yun Hongshen’s recent activities and searched his office. He presented his findings to Ke Jingping, who ordered Yun Hongshen to be suspended and reflect on his actions at home. After Yun Hongshen left, Ling Han expressed his confusion over Ke Jingping’s decision. Ke Jingping challenged Ling Han, pointing out that he had questioned Zhu He and Yun Hongshen, but shouldn’t he also question himself? Ling Han fell silent.
Returning home, Yun Hongshen saw Old Mrs. Yun embroidering something for Milan. Old Mrs. Yun asked him for his opinion of Milan. Yun Hongshen deflected, stating that it was his brother, Yun Hongqi, who needed to have an opinion. He questioned why his grandmother suddenly asked about Milan. Old Mrs. Yun recalled witnessing Milan catching the scissors and decided not to burden Yun Hongshen with more worries.
Milan met with Kunwu, who reminded her to focus on her mission and not get entangled with Yun Hongqi.
