After getting off work at midnight, Lin Wan returned to the rented Building 3 of Mingguang Community, only to find that the familiar environment had become strange and abnormal - mobile phones with interrupted signals, a silent community, a unit building with dry hair embedded in the peeling wall skin, and a "Temporary Rules for Residents" stained with suspected blood on the door handle, which completely broke the daily routine. This unsigned code lists many strange rules: it is forbidden to take the elevator on the left at night, you need to be alert to the sound of shuffling behind you, ignore the lights and sounds in Room 302, judge whether to open the door based on the color of the visitor's shoes, and even clarify that "this building does not have a fourth floor."
Before Lin Wan could digest these rules, she encountered the "shuffling sound" mentioned in the code and was approached by a strange old man. She suppressed her fear and retreated to the first floor to escape according to the rules. At this time, she received a message from her roommate Su Xiao, who not only saw the strange code, but also encountered a knock on the door with "the cat's eyes were dark", but the message failed to be sent. Lin Wan looked up at the fifth floor where Su Xiao was, and saw a blurry black shadow staring behind the curtains, and there was a warning "Don't trust Su Xiao" hidden in the code.
This strange encounter that started in the apartment building at midnight was not an accidental prank, but the first world of rules and ghost stories that Lin Wan accidentally got involved in. She must survive hard between abiding by the rules and being wary of those around her, and this weird Building No. 3 Is just the beginning of countless copies of the rules she will travel through.
