Gu Ling, the police legend who died, woke up and became the lowest-level patrolman of the "Demon Suppression Division". In this world where demons are rampant but "procedural justice" is emphasized, murderous and heart-eating demons can hire lawyers and get away with it by exploiting loopholes in the code.
