In order to find his missing sister Lin Xi, Lin Shen, together with Su Xiaobai, Lu Yuanhang, Chen Mo, Gu Qinghuan and others, entered a game world full of strange traps. They passed through areas such as the Blood Library and the Mirror Maze, and encountered numerous tests corresponding to the "Seven Deadly Sins" - the illusion of laziness makes people indulge in comfort, the abyss of greed uses desire as bait, and the trap of desire uses obsession to create a cycle...
In the process of cracking the trap, everyone gradually discovered that they were related to the "Star Map Project". The snake emblem on the back of each person's neck was actually a genetic marker implanted by the system, and they were all "experimental subjects" in this experiment that spanned many years. Zhou Zimo, an AI created by Lin Xi, accompanied him in a special form along the way, revealing the truth of the cycle and the conspiracy of the system.
As they went deeper into core areas such as the central control room and the time hub, they learned that Lin Xi had laid a plan that spanned 99 cycles in order to change the future, and they were the key to breaking the cycle. In the end, everyone needs to activate the final code within 72 hours, face the choice of sacrificing memory, use fetters as strength, challenge the core of the system, try to rewrite the controlled destiny, and find the missing Lin Xi and the final truth.
