In Shelter 404, administrator "Dawn" oversees humanity's survival two centuries after the world's end. Among the twelve billion who perished, Chu Guang emerges as an anomaly—his shelter system grants him the power to summon "players" from the pre-apocalypse, beings from a world long extinct. What began as a desperate measure transforms into something far stranger: the post-apocalyptic wasteland mechanics become indistinguishable from a game. The Federation of People issues its call for reconstruction, but darker whispers persist—DANCE… DANCE MY PUPPETS… As Chu Guang commands his summoned entities, reality bends under system parameters. The world has been unrecognizable since the cataclysm, yet within these digital frameworks, something unprecedented emerges: a civilization rebuilt through the lens of the very game that consumes it.
