By directing police to search Wiejie's shop, La Wen is able to produce a list of films that Weijie has recently watched.

Through this, she comes to the revelation that Weijie had been carefully constructing a falsified series of events through manipulating key witnesses, including restaurant owner Song En, and altering digital evidence, using his position as an internet technician to his advantage.

Convinced of Weije's guilt, but lacking the means to prove so, a frustrated La Wen resorts to extreme measures, torturing his family in order to extract a confession from An An, who, as the youngest child, is most vulnerable to coercion.

In order to further establish Weijie's guilt, La Wen directs the police to publicly exhume Su Cha's body from the local cemetery.

However, Weijie, suffering guilt from his actions, confesses to his role in the killing to La Wen and Du Peng, and is sentenced to prison.

It is heavily implied that Su Cha's body was earlier moved from the grave to a construction site that Weijie had been working on.
