Episode 10 recap: Pan Da Hai urged Cheng Bing to give up the investigation.

Lin Ying brought Cheng Bing back and said that everyone was ready and wanted to get together. Cheng Bing didn't want to go because they hadn't caught Wang Da Yong. Lao Ma and the others discussed and thought they should find a proper job for Cheng Bing so that he wouldn't have idle thoughts.

Xiao Xu asked Lao Ma to look for opportunities within their jurisdiction. Lao Ma said he didn't have that ability, but he did have a relative who was hiring. They were looking for someone to oversee a dam. Although it wasn't an official position, the benefits were the same as an official one. Everyone thought that if Cheng Bing had a job, he could start a new life.

Shi Tou came to find Cheng Bing and talked about his own investigation. He believed it was something everyone cared about, and Cheng Bing couldn't handle it alone. Shi Tou had previously argued with everyone, and they didn't want to be involved anymore. Shi Tou was unhappy and felt that they looked down on him.

Cheng Bing joined the gathering and talked about what had happened over the years. When he was in prison, he thought that eleven years would be extremely difficult to endure, and it proved to be true. He kept thinking about his time as a police officer, but eventually became numb to it. Cheng Bing admitted that when he was first released from prison, he wanted to live a peaceful life. However, when he saw Zhao Xiaomai's father, he knew he couldn't let the matter go. It bothered him deeply, so he had to catch Wang Da Yong.

Lin Ying approached Pan Da Hai and discussed the situation. Cheng Bing had promised to investigate using legal means and would inform them of any leads he found. Lin Ying agreed with Cheng Bing, considering his identity would make things more convenient.

Cheng Bing was applying for a passport, and Shi Tou also came. He said he was a loner and could go with Cheng Bing. He even sold his car, and if Cheng Bing didn't take him along, he would go alone. Pan Da Hai met Cheng Bing, who believed they could only investigate up to the border, but couldn't go beyond that.

Pan Da Hai mentioned they had channels for international cooperation.

Cheng Bing said that in 2000, they had investigated Chabang, but without any results. Pan Da Hai mentioned that after they received the lead, they reported it to the higher authorities and even sent people abroad to investigate, but they didn't find any clues.

Pan Da Hai stated that this matter had already brought chaos to his life and asked Cheng Bing not to involve his brother anymore. He admitted that he couldn't stop Cheng Bing from investigating, but he urged him to think it through. Lao Ma and the others came to see off Cheng Bing and gave him a bank card, which they had pooled together as investigation funds.

Cheng Bing and the others arrived in Chabang. When Cheng Bing was previously arrested, he had met someone who sold jade. That person came to pick up Cheng Bing, who had conducted some online investigation himself. He discovered that the snake tattoo on the gang leader was a symbol of the Brotherhood Alliance, and he believed that the gang members were likely connected to Wang Da Yong.

While Cheng Bing was investigating, he encountered a person who owed gambling debts and was being pursued by debt collectors, who were members of the Brotherhood Alliance. The Brotherhood Alliance members left, and Cheng Bing intervened when the person started abusing his wife. Cheng Bing gave them some money, frightened the person, and told him to stop abusing his wife. Cheng Bing questioned the person, but he only knew that members of the Brotherhood Alliance came to him; he didn't know where to find them.

Cheng Bing met someone at a bar who claimed to be able to introduce him to members of the Brotherhood Alliance. Cheng Bing and Shi Tou went with him, but unexpectedly, they were attacked and knocked unconscious as soon as they entered.
