In the face of a sudden catastrophe, a series of extreme weather events deprive human life, ultimately sealing the fate of human civilization in an icy grip. In this post-apocalyptic world, the surviving individuals reveal their inherent greed, leading to a complete breakdown of order. Lin Xuan managed to survive for four years in this frozen apocalypse. Unwittingly uncovering the truth about the survivor base, he fell victim to poisoning and treachery. However, unexpectedly, he is reborn to a time before the apocalypse, carrying the experiences of his past life. Armed with this knowledge, he activates the spatial abilities of a ring, begins stockpiling essential supplies, and constructs an underground shelter resembling a fortress. While others continue to struggle to fill their stomachs, he comfortably lies in the shelter, indulging in lamb legs and cola. Will this leisurely lifestyle continue indefinitely? Faced with unknown enemies, he must become even more powerful.
