In a modern city, the “Qingteng City Funeral Home” is actually a “Containment Center for Aberrant Creatures,” holding monsters twisted by contact with the “Door.”
The facility has 15 “Employee Survival Rules.” Each one corresponds to the behavioral logic of a particular monster, and breaking one triggers a death mechanism.
The rules are essentially a “monster-perception filter”: when humans follow them, monsters see them as their own kind, allowing them to evade the hunt.
