Episode 20 recap: Jiang Jiu Ping was being questioned.

When Gu Mu Lan brought Lin Ke over, it meant that they had finally managed to bring Miss Lin here. Now, with the seven of them, they were considered complete. Guo Mu Lan mentioned that the Golden Sheep Assembly was coming soon, and their Northwestern Wolves placed great emphasis on rules, valuing strength above all else. Each of them had to select a wolf cub, and the winner would become the Wolf King.

Pei Laosi looked around and remarked that things had changed while people had not. Only he remained from those days. Pei Laosi suggested that since they were here, they should follow the previous rules and have Chu Yi Han sit in his mother's seat and ask if Gu Lin Na dared to sit in his father's seat. Gu Lin Na promptly took the seat.

Pei Laosi instructed Chu Yi Han to translate the Desert Tiger's legacy, or else they wouldn't be able to leave today. Gu Lin Na stated that she only wanted to rescue her uncle, and A Ku informed her that her uncle had already left. Jiang Jiu Ping also messaged Gu Lin Na, asking her whereabouts.

A Ku mentioned that Gu Lin Na's visit today represented her father. Pei Laosi speculated that either Gu Mu Lan was dead or had lost his mind. Chu Yi Han proposed a condition: if he remembered the contents of both ciphers and could translate them, he would go with them. Chu Yi Han revealed several key points from the ciphers.

Pei Laosi hadn't expected Chu Yi Han to remember these details. He acknowledged that with that knowledge, they could report back. Chu Yi Han stated that since he had the information, who would still want to be a police officer? He demanded that Pei Laosi take his mother to the designated location, and he would claim a 50% share of the Desert Tiger's legacy. Pei Laosi agreed to give him 10%, but as for his mother, he couldn't comply.

Jiang Jiu Ping went to find Captain Xia. He informed them about what he knew, saying that in 2000, he had met his brother-in-law, and at that time his sister was already pregnant. The brother-in-law claimed his surname was Gu and he was in the fruit business. Although Jiang Jiu Ping felt something was off, he didn't say anything because his sister liked him.

Jiang Jiu Ping mentioned that it was five years ago when they dismantled the Northwestern Wolves organization, and he saw the news on TV, realizing that his brother-in-law was Gu Mu Lan.

They inquired about his son-in-law, and Jiang Jiu Ping stated that he didn't know what he did for a living. He emphasized the importance of a harmonious family and said that he would accommodate him.

Duan Qing mentioned that Mu Shao Bai had already died, and the suspect was Cheng Fan. Jiang Jiu Ping explained that due to poor medical conditions in their area and his heart condition, he had invested in Mu Shao Bai to seek treatment. However, he also admitted that he didn't know what Mu Shao Bai's occupation was.

Duan Qing proposed to go and take a look at the Buddhist hall, and Jiang Jiu Ping agreed. He led them there, expressing his confusion as to why they were targeting his Buddhist hall. They conducted a search but found nothing significant. Pei Laosi suggested that since they were here, they should follow the rules of the Northwestern Wolves from the past, and whoever wins would become the new Wolf King.

Gu Lin Na fought against them, and in the end, she emerged as the victor. Sha Xiao Fei instructed Yi Yi to leave and gave her a USB drive, telling her to tell the police that she was raped by him. Yi Yi claimed she didn't know what her father did and that she had no involvement in these matters; she was coerced into fleeing.

Yi Yi disagreed, stating that if they were going to die, they would die together. Sha Xiao Fei urged her to leave quickly. Yi Yi informed Duan Qing and the others about what she knew. Duan Qing asked why Sha Xiao Fei abandoned her, and Yi Yi believed that Sha Xiao Fei had never intended to come back alive.

Jiang Jiu Ping went to meet Cheng Fan, and his responses were tight-lipped. Cheng Fan informed Director Tai that although Jiang Jiu Ping seemed fine, he found it suspicious, suggesting they should investigate further to determine if Jiang Jiu Ping was a jackal in the Northwestern Wolves.
