The universe is a giant network of cause and effect, and all impossible events are holes in the network; the resurrection of the dead, chaos in time and space, and urban ghost stories are all manifestations of the imbalance of cause and effect.

He formed a team with former detective Su Qing, genius hacker Chen Feng, and kind-hearted doctor Ye Zi to break through the cycle of dead souls on the midnight bus No. 13, Break the haunted puzzle in dormitory 404, step into the reincarnation of civilization in the fog of history, and break through the mythical copy of Ragnarok.
But as the "Yesterday Reappears" brand awakens, he sees that the disappearance of his sister Lin Xi hides the system's shocking secret: the system is not repairing loopholes, but harvesting civilization; his sister is actually the only consciousness at the core of the system!
