Murong Chen is, on the surface, a foreign-style forensic consultant at the Shanghai Public Settlement Patrol Room. Because he had studied in the West, was proficient in the latest forensic science, and had an elegant manner, he was highly valued by his superiors. But no one knows that he comes from a family of assassins who were wiped out by feuds. His adoptive father taught him the "Law of Darkness" and specializes in killing villains who cannot be punished by the law.
