Lin Weimian received a high-priced part-time job: staying in "haunted houses" throughout Qiyun City, trying to sleep for seven consecutive nights, and submitting a safety experience report to the rental platform. On the first night, she stayed in Beluga Apartment 404. At 2:17 in the morning, there were three short and one long knocks on the door. The woman outside the door said she was a tenant of 1306 and came to pick up the key left at the front desk. But Beluga Apartments doesn't have a thirteenth floor or a front desk. On the second night, the person knocking on the door was a delivery boy holding a box; on the third night, it was a boy wearing an old school uniform; on the fourth night, it was a pregnant woman wearing pearl earrings. Each "tenant" said that he had booked a room, and after everyone left, he would leave an object related to the disappearance of Yuntang Hotel eleven years ago. Lin Weimian wanted to write a normal sleep trial report, but found that the "no door opening" clause in the platform contract, the abnormal records of the smart door lock, and the footsteps coming from the wall were all pushing her to a non-existent floor. Insurance adjuster Ji Yao also lived in the same building. He told Lin Weimian: The so-called haunting is often the best disguise for living people. But if all the evidence points to a living person, why was the tenant who knocked on the door every night declared non-existent eleven years ago?
