College student Chen An accidentally falls into an eternal-night survival world, where everyone is confined to a cramped room and monsters will break through the door to attack at night. Chen An draws the god-tier talent "Only I Reign Supreme" and becomes linked to 100,000 residents in his residential community. As long as the residents survive, he can obtain vast quantities of survival supplies every day. He follows the survival rule of keeping a low profile and staying alive, first reinforcing his own fortress, then making allies and building a resource trading system. He mediates conflicts among residents and organizes everyone to band together against the monsters. With the support of 100,000 residents, he leads everyone in struggling to survive through the endless eternal night and builds a home for the survivors.
