Weird Story About Rules: I Work as a Security Guard in a Ghost Building

After Zhou Yan traveled through time, he became the night shift security guard of Yong'an Building. On his first day at work, he discovered that something was not right about the security manual: [This building does not have a thirteenth floor. [After twelve o'clock in the morning, do not answer people in the elevator. [If you see yourself standing behind you on the surveillance camera, please eat a bear biscuit immediately and write in the duty log: I am still alive. Zhou Yan thought it was a prank. Until midnight, the elevator stopped on the thirteenth floor. When the door opened, his mother, who had been dead for seven years, stood inside. "Xiao Yan, mom has been waiting for you for a long time." From that day on, Zhou Yan knew that this building was not for living people. It is a container for suppressing evil spirits. As a security guard, he is responsible for registering, mediating, containing, and suppressing ghosts. The Hanged Ghost complained that the next door was too noisy, the Headless Ghost asked for facial recognition to be installed, and the Elevator Ghost was stuck on the thirteenth floor every day. Zhou Yan looked at the increasingly outrageous household registration form and silently opened a pack of bear biscuits: Living people must register when entering the building. The same goes for dead people.
