Episode 36
Lin Shengwu was ambushed by Lin Can. Lin Shengwu called Lin Zonghui and said goodbye after his shot fell. Lin Shengwu committed suicide with Lin Can’s pistol. Lin Zonghui finally called Li Fei’s phone. At the same time, Lin Can also found out where Lin Shengwu was based on reasoning. Li Fei found the evidence according to Lin Zonghui’s instructions-the mobile phone, and immediately transmitted the video to his mobile phone. Li Fei asked Cai Yongqiang to help eliminate his traces. Lin Can got the original video, and Lin Yaodong finally felt relieved. Li Fei found that in the video, Ma Yunbo accepted three million bribes. It turns out that Ma Yunbo, whom he has always trusted most, is the real umbrella of Tazhai.

Episode 37
Li Fei sent the video to Cai Yongqiang, who suspected that Li Weimin had not been investigated. Lin Yaodong called Zhao Jialiang and asked him to come to Tazhai. Li Fei sent the copied video evidence to the provincial department. Lin Yaodong decided to enter into a deal with Zhao Jialiang. Li Weimin, who pretended to be under investigation, finally stopped hiding and appeared to preside over the anti-narcotics operation with Tazhai and Lin Yaodong as the investigation objects. Li Fei, who followed Zhao Jialiang for several days, finally annoyed Lin Can. Zhao Jialiang watched his son being beaten with his own eyes, but he could only pretend nothing was happening. Zhao Jialiang decided at this time to expose that he was the dark web buyer that Lin Jingwen had been in contact with.

Episode 38
Lin Yaodong arranged a fake deal for stealing the bar. Li Fei told Cui Zhenjiang that Lin Yaodong and Zhao Jialiang had a deal today. Based on his experience, Li Weimin accurately judged that this was a fake transaction and insisted on keeping his troops. Li Fei got the news from Lin Zonghui and was arrested by Cai Yongqiang. Cai Yongqiang pointed out that Zhao Jialiang might be Li Weimin’s informant, so Li Fei should not act lightly. Zhao Jialiang asked his men to inspect the goods and found that the drugs were transferred. Because of Li Weimin’s tacit cooperation, Zhao Jialiang finally won the trust of Lin Yaodong.

Episode 39
A two-ton deal is ready to proceed. Li Fei suspected that Zhao Jialiang was his biological father. Zhao Jialiang used the salesperson’s cell phone to notify Li Weimin after she dropped the person under surveillance. Ma Wen deliberately cut Zhao Jialiang’s hand, and Li Fei performed paternity tests with Zhao Jialiang’s DNA. The provincial department that received the transaction information immediately carried out various deployments, and the “ice breaking operation” officially began. Zhao Jialiang deliberately put on the coat Li Fei bought for Li Weimin. Li Fei confirmed that Zhao Jialiang was Li Weimin’s informant. Li Fei asked Zhao Jialiang to meet, but Zhao Jialiang was abducted by Lin Yaodong. Li Fei received an order to meet Li Weimin at the Provincial Department, and learned that everything was a bureau laid by Li Weimin.

Episode 40
Lin Yaodong performed Zhao Jialiang’s final test, and scopolamine lie test. Zhao Jialiang’s wife was killed after being injected with scopolamine for smuggling. Zhao Jialiang was more convinced that Lin Yaodong was the murderer of his wife. Zhao Jialiang, who had already trained himself many times with scopolamine, passed a polygraph. Zhao Jialiang’s men abducted Lin Yaodong’s son. The two-ton drug deal is set for twelve days. Lin Yaodong asked Ma Yunbo to meet with Zhao Jialiang for the last time. Ma Yunbo recorded Lin Yaodong’s words. Ma Yunbo asked Li Fei to eat at home. Li Weimin suggested attacking the west and deploying icebreaking operations under the guise of hitting Hedong County.
