After graduating from high school, the protagonist, Yang, passes the civil service exam. However, despite his desire for a stable life, he is inexplicably assigned to the special department known as the M Department, which is tasked with dealing with transformed humans. The members of the M Department primarily use special weapons to combat these transformed humans, who blend into the crowd by appearing as ordinary people. (Source: iQIYI, translated)
