When Colin woke up with a hangover in the bathtub, the 72-hour countdown on his wrist was mercilessly announcing: Welcome to the "Between Reincarnations" death game. In this virtual purgatory built by the quantum computer "Gaia", the murder copy that is reset in each round hides fatal traps, and the participants are both puzzle solvers and each other's prey. Colin, a former programmer, used his iconic complaint that "this game planning should be a chicken leg", looking for loopholes in the secret room murder case in Blizzard Villa, and calculating survival in the gravity maze of the upside-down hospital. However, when he teamed up with the calm and ruthless survivor Lin Xia, he discovered that there was a more terrifying truth hidden behind this laughing and scolding survival battle - the lives lost in the game are turning into bioelectricity to maintain the operation of the system.
With the rules of Ah Jiu (the AI host who Colin always complained about the program being disordered) being subverted again and again, the secrets to pass the game peddled by the mysterious doctor Lao Bai, and the girl in the red dress that appeared repeatedly in the memory fragments, Colin gradually pieced together the truth: This is not only a death screening that connects parallel time and space, but also an ultimate gamble with the real world as the bet. When he and Lin Xia led the team to stand in front of the final level, Zero, the consciousness of the game creator who appeared in the form of a 12-year-old boy, posed the most cruel multiple-choice question: passing the level meant the complete annihilation of the real world, and their struggling souls were nothing but reserves for the interstellar colonization plan. On the scale of human nature and survival, Colin's sense of humor lost weight for the first time, leaving only the ultimate mystery that must be answered with life.
