In the eighth year of the extreme-cold apocalypse, Lin Shi is betrayed and shot dead by his brother Zhao Xiao after their supplies run out. Unexpectedly, he is reborn three days before the apocalypse begins. Using the Treasure-Gathering Basin left behind by his father, he awakens two supernatural abilities: spatial storage and item duplication. He sells his house, buys gold, frantically stockpiles supplies, and builds a secure shelter on a mountaintop while upgrading his powers. After the world freezes over, Lin Shi tames mutated beasts, including the Demon King, a dog with heterochromatic eyes. By absorbing source energy, he unlocks genetic locks and steadily rises to power in the chaotic new world. But when a beast tide that was supposed to appear years later arrives ahead of schedule, an even greater crisis suddenly descends.
