Lin Mo, who was unemployed and homeless, gritted his teeth and rented Room 502 of Xingsheng Apartment with a monthly rent of only 300 yuan in order to survive. The landlord's saying "don't regret it when you come" was just a quirk of the old house at first. It wasn't until he saw the six rules on the yellowed paper on the inside of the door that he realized something was wrong - there is no fourth floor in this apartment, no answering after ten o'clock in the evening, no eye contact with white figures, no touching of red objects...
Late at night on the first night, regular knocks on the door came as expected, and the white shadow wrapped in white mist behind the cat's eye made him fully understand that these rules were not taboos, but life-saving charms. The old copper button passed down from his ancestors was unexpectedly cool, causing Bai Ying to stop for a moment. This inconspicuous jewelry became his only support in the strange apartment.
If the wardrobe is left open for too long, cold lines will appear, the portrait in the corridor will quietly turn its head to warn, the old TV will turn on independently and a white shadow will appear, and a seductive female voice will be heard from the boarded-up fourth floor... Every time the rules are tested, it will be a brush with death. Fortunately, he met Su Qing, a nurse who was also trapped, and the two formed an alliance. While exploring the rules, they also discovered more secrets of the apartment.
There is more than one kind of weirdness. The landlord deliberately conceals the truth about the fourth floor and room 501, and the power of the copper buckle is gradually declining. They must not only resist strange attacks that may appear at any time, but also actively explore for clues and solve the mystery behind the rules. In this life-devouring apartment, you can only survive by abiding by the rules and finding ways to fight against the weirdness. As the exploration deepened, they discovered that the strange resurrection of the apartment seemed to have targeted every intruder.
