An accident occurred in Jiecheng, and Wang Dayong's ID card was found on the deceased. Pan Dahai came to Jiecheng for this matter and learned that the body was sent to the provincial capital for testing.
On the other side, Cheng Bing and others continued to investigate the rough stones. Through Huang Lao from the Rough Stone Appraisal Association Center, they learned that the rough stones had appeared here in 2005.Afterwards, Cheng Bing and others discussed and decided to investigate around the stone while keeping an eye on Zhang Shuqiao.
Zhang Shuqiao was brought for interrogation by Pan Dahai, who revealed that everything had been done by the missing Gu Erqiang.
Cheng Bing learned that Pan Dahai came to Jiecheng and knew that Pan Dahai came for Wang Dayong, and then received a call from Pan Dahai wanting to meet him.
When Cheng Bing saw Pan Dahai asking for clues but failed, he told Pan Dahai the clues he got through Huang Lao.
On the other side, Zhang Shuqiao received a call and was going to the police station for interrogation. When she left, she did not forget to tell her brother to let A Guang fish her out on time.
Facing the interrogation, Zhang Shuqiao told the story of the stone purchase that year. Gu Erqiang was dissatisfied with the seller's betrayal and wanted to steal the materials.Through identification, Zhang Shuqiao determined that the seller was Wang Dayong.
When Shitou asked an agent to borrow a car, he told the agent what they were doing. Afterwards, he told Cheng Bing about it, and Cheng Bing thought it didn't matter.
Boss Qian saw Zhang Shuqiao's brother who came to beg to fish out Zhang Shuqiao, but he was unwilling to help.
Cheng Bing pretended to free Zhang Shuqiao by talking to Zhang Shuqiao's brother. He learned from Zhang Shuqiao's brother that someone had picked up Gu Erqiang's ID card back then, and he ignored the call.
