Natural disasters and mutations have come, and all humans have become players in this game. In this doomsday game, everyone can bind a shelter of their own, and upgrade or protect their own shelter through NPCs summoned by various cards scattered around the world. There are professional NCP cards such as swordsmen, assassins, archers, and craftsmen, as well as weapon cards such as flaming swords, sky-shattering axes, and firearms, as well as blueprints for various powerful props! Upgrade and develop your own professional NPC to unlock stronger functions! Lu Tu, who has returned from rebirth, activates the lottery system, doubling the probability! Get super rare cards! [Mechanics, smelters, elf archers, kingdom swordsmen] and other ultra-rare NPCs are coming one after another! Build your own god-level shelter!
