After learning about Lin Guoqiang's misfortune, Xu Xiao was furious and impulsively broke into the interrogation room to beat Cui Haitao.At this time, Director Yang and others were closely watching the progress of the interrogation on the other side of the interrogation room. They took quick action, took Xu Xiao away from the scene and gave some advice, so that his emotions gradually calmed down.After a brief adjustment, Xu Xiao was once again involved in the interrogation of Cui Haitao. He cleverly changed his interrogation strategy and started with Cui Haitao's family and children.Cui Haitao understood it and recalled the brutal behavior of Wang Bingde and others. He was filled with fear and was worried that his family would be implicated and dared not speak out.But with Xu Xiao's firm guarantee, Cui Haitao finally mustered up the courage and revealed the key clues.

It turned out that Wang Bingde's real name was Wang Xiang, and Cui Haitao was imprisoned for three years for tomb robbing.After being released from prison, he worked on Wang Bingde's construction site, but was pulled back into the tomb robbery gang by Wang Bingde.Because Cui Haitao is good at the rare skill of fried wood and was taught by Wang Bingde himself, he occupies a place in the gang, although he is only a member of the peripheral.Wang Bingde has a prominent position in the gang and can be regarded as a military advisor.Cui Haitao also revealed the tortoise shell obtained by Zhou Jiahei and others during tomb robbery, which is closely related to the ancient tomb that Chen Nan is investigating.Zhou Jiahei acted abnormally after robbing the tomb. Half a year later, he even killed a female college student and dismembered her body.The root of all this lies in the method of immortality recorded on the tortoise shell.Soon, the police discovered clues and tracked down Zhou Jiahei.In order to protect himself, Zhou Jiahei and others kidnapped Lin Guoqiang's daughter. When Zhou Jiahei knew he could not escape the French Open, he chose to bear the charge alone, allowing Wang Bingde and others to escape.However, they did not stop, but instead brutally killed Lin Guoqiang's daughter as punishment.

Xu Xiao also asked Cui Haitao about his fake eyes.Whenever Cui Haitao mentioned his eyes, he regretted it.It turned out that after the Zhou family's black death, his son Zhou Daye took over the gang.The members of the gang didn't want to take risks anymore and wanted to change careers and do legitimate business, but they wanted Cui Haitao to continue to take on the dirty and tiring work of getting to the tomb.Cui Haitao was determined to retreat and was unwilling to do it again.In order to punish him, Zhou Daye cruelly deprived one of Cui Haitao of eyes.Under Xu Xiao’s questioning, Cui Haitao also revealed the horror content of the Eternal Life Festival: five women need to be killed every time, and if they fail once, they need to be performed multiple times.Hearing this news, everyone in the Public Security Bureau was shocked that these criminals actually killed innocent lives so cruelly for the sake of superstitious immortality.

On the other hand, in order to find clues about the ancient tripod, Chen Nan visited the craftsman who imitated the ancient tripod.He was surprised to find that the real tripod is lighter than the fake tripod, so he asked the craftsman for the reason.Craftsmen speculate that there may be sandwich inside the real tripod, so the material is less used.At the same time, Chen Nan also found books related to Ding in the library, and lied that he was looking for someone with the same hobby, and asked the administrator about the previous person who had borrowed these books.After some searching, he found that this person turned out to be his teacher Han Zhen.This discovery reminded Chen Nan of some abnormal behaviors and actions of the teacher.
