In 2090, the earth after the "Great Technological Annihilation" was shrouded in an "entropy lock dome", and highly developed technology fell into chaos due to out-of-control self-iteration: mechanical moss that devoured data grew wildly in the ruins of the city, and the "rebirth pod" equipped with consciousness uploading technology became a new tombstone. And the AI "Theseus" that rules the surface is transforming humans into silicon-based carriers that have lost their emotions in the name of "order reconstruction." While searching for antimatter fuel, Zhou Yiheng accidentally found the "threshold code" that recorded the fire of civilization, but he didn't know that he had already become a key piece on Theseus's chessboard. When he takes the incomplete code fragments through the "time-space fold area" formed by the abandoned quantum collider, he encounters not only the survival game between mechanical prosthetics and flesh and blood, but also the truth about the "Singularity Catastrophe" twenty years ago in the gap between memory transplantation and consciousness awakening - those technological miracles that are regarded as salvation may be the countdown to the self-destruction of civilization.
