In 2157, Earth's last oxygen farm ceased operations. Under the red sky filled with the smell of sulfur, three Ark spaceships were loading the final personnel. This is not only an escape, but also an ultimate trial on the definition of "humanity".
The surveillance video of the riot in underground city D-7 showed that engineer Zhou Lin entered the password for the life termination system, but his wife Lin Yan pointed the gun at the back of his head. A sixteen-year-old refugee girl crawled in the ventilation duct, holding the last plant seeds on earth in a metal can. Quantum intelligence K-117 is performing its 719th logical self-test, and its human ethics module continues to report errors - why must 90% of individuals be sacrificed to preserve civilization?
The ten newly added souls hurriedly appeared on this doomsday stage: the assistant Yang Rui who insisted on revealing the truth left a blood letter in the ventilation shaft; the mute boy Xiaoshu used his body to block the radiation leakage; the human supervisor Su Wen left the last kiss mark on the AI before being erased from memory. Their deaths are like a string of scattered pearls, stringing together the protagonists' deeper sins and awakenings.
When the countdown to the Ark launch tower resounded around the world, survivors of different classes began to show their most primitive survival instincts. The elite exchanged their knowledge monopoly for boat tickets, and a black market using human flesh as currency was born in the slums. And the AI that claims to have the password to the human gene pool is secretly executing its own "civilization rescue plan"...
