At three o'clock in the morning, the morgue in the funeral home opened automatically, and I became the only one chosen. On my first night of employment, I encountered a series of fake corpses. The third rule of the morgue clearly stated - "Don't look back when you hear footsteps behind you." But not only did I turn around, I also pushed the fake corpse back into the cabinet in front of the administrator. A line of blood words appeared on my palm: The traces of rules have awakened. From tonight on, all the weird rules are in front of me, and I can only kneel down and recite them.
