A catastrophic global ice age strikes without warning, sending temperatures plummeting to over 70 degrees below zero. In his previous life, Zhang Yi was kindhearted and shared his supplies with others, only to be murdered by Fang Yuqing and a group of neighbors. Reborn one month before the disaster, he awakens a storage space ability, empties warehouses worth tens of billions of yuan, and spends a fortune building an impregnable alloy fortress as his safe house. When the apocalypse arrives, neighbors and a manipulative fake innocent repeatedly come begging for supplies and even attempt to break into his home. Zhang Yi coldly protects himself and refuses to show mercy, watching as the greedy people suffer the consequences of their own actions amid the freezing cold and starvation.
