Law students Si Qing and Song Shi worked part-time in a milk tea shop. One day they accidentally went to the restaurant opposite and found blood seeping through someone's clothes, pills in someone's cup, and someone signing an infinitely extendable contract in blood... However, the boss handed him a menu, and the first line said, "My death is a perfect crime." From then on, Si Qing and Song Shi memorized the law during the day and investigated dirty cases at night. Whenever they solved a case, big blood-red characters slowly appeared on the last page: the dock: Human World.
Purpose: Justice may get lost, but there are always people willing to be its beacon.
