Lin Yu, who comes from a police family, is a calm, wise and experienced police detective. In the seemingly peaceful city, a series of bizarre murders suddenly broke the tranquility. The deceased were unrelated, but they all died in strange ways, leaving mysterious symbols and elusive clues at the scene. As the investigation deepened, Lin Yu was shocked to realize that behind this was a huge mysterious organization that used multinational companies as a cover to control finance, smuggle organs, and sell weapons. This organization has been rooted in the city for hundreds of years, colludes with politics and business, acts viciously, selects members strictly, and has influence all over the world.
