When the late night streets were swallowed up by a strange white light, Su Ran fell into a fatal reincarnation called the "Cage of Rules." Every copy here is a rules meat grinder - the double-faced nurse wandering in the abandoned mental hospital, the backward death clock in the campus bell tower, the alien creature with parasitic consciousness in the starship... Every rule hides murderous intent, and every breath may touch the red line of death.
What's even more cruel is that participants not only have to fight against the supernatural horrors in the dungeon, but also beware of the hidden arrows of those around them. The selfish and ruthless Zhao Gang will do whatever it takes to get resources, the mysterious old man is always controlling from the dark, and the seemingly fragile Lin Yao hides an amazing secret. In this world with limited resources and life and death in a blink of an eye, trust has become the most expensive luxury product, and self-fighting and cooperation are intertwined into a paradox of survival.
Su Ran awakened the "Rules Insight" power, and discovered on the edge of life and death countless times: at the end of all the terrifying rules, there is the ultimate truth that devours everything. Become a prisoner of the rules, or a trapped beast that breaks the cycle of reincarnation? When cannibalism becomes a survival instinct, can he tear apart the hypocrisy of this treacherous world in the infinite self-fight?
