History
After a series of investigations, the police roughly locked onto a suspect named Zhou Xiao, but they never caught him.

At this time, the internal variables of the task force appeared. There was evidence that Song Lang was involved in the third murder. His fingerprints had appeared at the crime scene. Coincidentally, the victim of this murder was someone that Song Lang hadn’t arrested due to a lack of evidence. In other cases, people began to suspect that Song Lang took the opportunity to kill people by acting as a copycat killer.

The task force temporarily suspended Song Lang, but he continued to investigate it alone. One night, several gunshots alarmed the police. When the police arrived, they found Song Lang's partner Qin Luoxi and his boss Li Mu in a pool of blood. The cause of death was suspected to be gunshot wounds.

Later, Song Lang's fingerprints, footprints, and bloody fingerprints were found at the scene. The police determined that Song Lang was the primary suspect of the murders and began to hunt him down. Song Lang was never found.
