In the modern urban context, "Ivy City Funeral Parlor" is actually an "abnormal creature holding station", which houses monsters that have been twisted due to contact with the "door".
There are 15 "Employee Survival Rules" in the museum. Each rule corresponds to a kind of monster behavior logic. Violation will trigger the death mechanism.
The essence of rules is a "monster cognitive filter": when humans follow the rules, they will appear in the same kind of form in the eyes of monsters, thus avoiding hunting.
