The “Singularity” arrives, allowing human consciousness to be uploaded to the virtual paradise known as the “Eternal Realm.” But this is no selfless gift. Once the last person has uploaded, time in the real world will restart, and all physical existence will vanish, becoming the ultimate energy source that powers the Eternal Realm. Lin Zhou, the protagonist, is one of the few “insulators” immune to uploading. In the final 100 days of civilization’s countdown, he must choose between false prosperity and a brutal reality.
