Level Zero

Everyone is trying to break through, but I am looking for an exit. The Judgment Tower has descended on the earth, and all mankind has been involved in a hundred-level clearance game. Veteran Fang Qi discovered a line of small words that had been crossed out in the rules text at the first level - that was the entrance to "Level Zero", the debugging layer left behind by the builder of the Judgment Tower. There, he saw the truth: this tower is not a game, but a cage; you are not players, but materials. When everyone was climbing up, he was the only one who chose to go down.
