Hide and Seek: Start with an Abandoned Elementary School

At eleven o'clock in the night, Ye Cheng was lying on the bed in the rental house, challenging the "Horror Hide and Seek" game on his mobile phone for the 107th time. Abandoned elementary schools, mental hospitals, late-night department stores, underground parking lots, she could recite the routes for each level with her eyes closed. The moment she passed the last level, a ball of golden light exploded on the phone screen, sucking her whole body into it. When she opened her eyes again, she was standing in the corridor of a real abandoned primary school. The walls were peeling off, the water reflected light, and children hummed nursery rhymes in the distance. A line of text popped up on the phone: Welcome to the real-life horror hide-and-seek. If you are caught, you will die. She was just an ordinary office worker who didn't even dare to watch ghost movies. She didn't have a golden finger or a big boss to guide her. The only thing she could use was the rules and maps she had memorized after playing the game hundreds of times. But the real-life version is completely different from the games she has played - the safety positions will fail, the props will be deceptive, and the seemingly safest corners are precisely the places where hunters love to dig. The "ghosts" in each level have their own rules. While others were screaming and running around, she squatted in the corner and dug out the words of the rules; while others were fighting for props and heads, she wrote down the number of times each prop was used and the cooling time. After escaping from death again and again, she changed from a newcomer whose legs weakened when she saw the shadow, to "Player 007" who gave hunters a headache. When a teammate fell, she pulled him away; when someone tripped him, she slapped him in the face and went back. She gradually discovered that there were living people hidden behind this game - some people used players as consumables, and some people made money by live streaming the players' fears. The abandoned elementary school seemed to be related to her childhood memories that had been missing for many years. What is it?
