We fought a hundred-year war for non-existent humanity.
"Natural disaster" comes, and the human fleet defends the frontier of civilization. After hundreds of bloody battles, victory is imminent, but Commander Lin Yan receives the highest order of the galaxy: "Human civilization was extinct 1,200 years ago. Please stop meaningless resistance and implement the archiving process." When faith collapsed, the core protocol of the battleship AI Noah suddenly unlocked, pointing to a forbidden coordinate - the "Well of Origin." On the way to escape, they discovered that the "natural disaster" was actually a systematic cleaning program, and the "Return to Zero" sect that was chasing them was actually composed of compatriots who voluntarily accepted extermination. When the heroes of the virtual world are reduced to system bugs, and when the meaning of existence is reduced to data to be archived, Lin Yan must lead the remnant through the sea of memories and find the last compatriots who may have been "silent" in the cold desert of the real universe. And they also carry the final key that is enough to restart—or end—the two worlds.
