Reborn three days before the apocalypse, Ye Su remembers the horrors awaiting humanity: a zombie virus, a freezing cold front, global floods, and alien invasions. In his past life, he died helplessly, but now he possesses a unique Team-Up System. To survive, he must recruit individuals with specific professional talents, forming unbreakable bonds to unlock legendary shelters and infinite storage spaces.

His first recruits include a terrified neighbor and a skilled warehouse administrator, granting him a massive underground brass fortress and a spatial warehouse. However, Ye Su's ultimate goal is far grander than mere survival. He aims to gather a vast array of talented women to construct an impregnable sanctuary, transforming a simple bunker into a thriving Kingdom of Women amidst the ruins of civilization.

As disasters escalate, Ye Su must navigate betrayal, monsters, and the elements, proving that his harem-filled stronghold is the only true refuge in a dying world.
