Weird Rules: Never Fill in the Fifth Blank

[Strange stories about rules + rules maintainer + unlimited copy flow + suspenseful wits + memory price + self-tracing] There are ten deadly rules for residents posted in Xingfu Apartment, but the fifth one is blank. The delivery boy accidentally broke in, but because he couldn't complete the clause, he was swallowed alive by the wall, and his name was engraved in the blank space. Lin Yan accepted a three-time urgent repair order, but found that in the death file ten years ago, the deceased had the same name and appearance as him. Someone has tampered with the rules and forged files, and the shameless neighbor is waiting for an opportunity to break in. The lives of forty-seven people in the entire building are hanging by a thread. A yellowed ticket stub contains a warning: Don't make up the fifth item. But something in the wall is waiting for my signature - the fifth original text that disappeared that year hides the truth about my death that I have long forgotten.
