In a modern society where ghosts and ghosts must obtain a certificate to work and strictly abide by the "Supernatural Employment Law", "rules" are the only criterion to maintain the balance between the two worlds. Chen Gui, the top investigator of the Supernatural Compliance Department, has believed in and defended this system throughout his life.
Until he took over a series of bizarre cases: those great demons who were fully compliant and had excellent performance actually fell into collapse and madness one after another in their "legal" jobs. All procedures are impeccable and all operations comply with regulations, but tragedies continue to breed in the gaps in the terms.
Stereotypes were forced to face a cold truth - some rules were born to be exploited; some systems were designed with deadly malice in mind. When perfect order becomes the most exquisite weapon, should you continue to defend your lifelong beliefs, or should you personally uncover this cruel conspiracy based on "compliance"?
He must make a choice before the rules swallow everything completely.
