After My Mother Retired, She Became the Building Manager in Rules and Ghost Stories

Before my mother lost contact, she only sent me one sentence: "There is soup in the pot, remember to heat it up." When I rushed home, the soup was still warm, but she disappeared from the elevator surveillance. When she reappeared, she was standing on the non-existent 18th floor, with rules written in red on the wall, and a fake property manager knocked on the door to check the water meter. Others talked about how to survive and hide, but she put on her reading glasses and took out a small book: "Check the water meter and report your work number first. How many people in the house will register first? Who will seal the fire escape will be revealed tomorrow morning." She saves people in ghost stories, but the real world is forgetting her little by little.
