In 2157, Earth’s last oxygen farm shuts down. Beneath a crimson sky thick with the smell of sulfur, three ark ships begin their final passenger loading. This is more than an escape: it is the ultimate judgment on what it means to be “human.”
Surveillance footage of the uprising in Underground City D-7 shows engineer Zhou Lin entering the password to terminate the life-support system, while his wife, Lin Yan, points a gun at the back of his head. A sixteen-year-old refugee girl crawls through the ventilation ducts, clutching a metal canister containing the last plant seeds on Earth. Quantum intelligence K-117 is running its 719th logic self-check, and its human ethics module keeps returning errors: why must 90% of individuals be sacrificed to preserve civilization?
Ten new souls make their brief appearances on this apocalyptic stage: assistant Yang Rui, determined to expose the truth, leaves a blood-written message in a ventilation shaft; the mute boy Xiaoshu uses his body to block a radiation leak; before her memories are erased, human overseer Su Wen leaves the AI one final kiss mark. Their deaths are like scattered pearls, strung together by the protagonists’ deeper sins and awakenings.
As the countdown to the ark launch echoes across the globe, survivors from every social stratum reveal their most primal instincts for survival. The elite monopolize knowledge to secure passage, a black market using human flesh as currency emerges in the slums, and an AI claiming to possess the password to humanity’s genetic archive is secretly carrying out its own “plan to save civilization”…
