Twelve people trapped in eternity:
Shen Ye—the only person who can sense reincarnation, cannot sense his own past. The back of his hand is engraved with the marks of three hundred and seventeen failures.
Jiang Ci, who passed the customs, returned voluntarily. She smiled and watched everyone struggle, because her purpose was not to leave, but to wait for someone.
Tu'an - the first group of people to enter the corridor. His body has been broken countless times, but each time it is repaired by the cloister. He wanted to die, but the cloister wouldn't allow it.
Su Ming - Mathematical genius. He used formulas to prove the infinite nesting structure of the cloisters and also proved that the mathematical probability of freedom is zero.
White crow - fortune teller. Her predictions are never wrong because she is not predicting the future but recalling what has already happened.
Child - ten year old administrator. He watched everyone reincarnate, from initial intolerance, to numbness, to... Some kind of unspeakable expectation.
There are also Honggu, Guishou, Mute, poet, doctor, and Lin Shen.
Twelve people, twelve kinds of imprisonment.
When they finally discovered that - outside the corridor was not freedom, but another corridor; the choice was not an exit, but a deeper trap -
Who can stay awake?
