Shocking Disguise

Tao Youyou originally just wanted to get the one thousand yuan. An abandoned teaching building, twelve strangers, a "secret room escape". After the door closed, she realized she couldn't get out. The chalk dust in the corridor is real, the reflection in the mirror room will turn around on its own, the end point of the permanently frozen carriage is a bottomless lake under the ice, and there is a copy of forced entry... She is smart, calm, and survives the deadly levels with a paper knife in hand. The boy next to him in a white sweater had been following her from the first level, and he relied on her to guide him every step of the way. She was even a little proud. At the last level, when she stabbed the knife into his heart, he coughed up blood and laughed. "The first level," he said, "when you said you were afraid of the dark, you were actually touching a knife, right?" All the clues, hints, and ways to survive in the level were all the bricks he laid under her feet. He pretended to be a whole game, leading her here step by step from the moment she touched the knife. She won. He is dead. Game over. But the door wasn't closed. New levels are still growing. And she began to wonder - was the dead Shen Kebai really dead?
