The correlation is as follows

The police took the young Han to the police station for questioning. He denied killing, and he was calm. Even if the polygraph failed to detect it, the police released Han without evidence. From that day on, Han's determination to continue killing people was strengthened.

15 years later, he became a murderous maniac, targeting the families of those killed by Han, and Gao Wuzhi became a criminal policeman. Influenced by childhood, Gao Wuzhi is very concerned about abnormal homicide cases. Once he hears about this situation, he will go there as soon as possible.
