Three years into the apocalypse, delivery driver Wang Ze was shoved into an ice cavern by his girlfriend Lin Weiwei and his enemy Fang Yi, who joined forces to steal his supplies and cut off his escape. He died with his eyes open. When he opened them again, he was reborn seven days before the Blue Snow arrived, with a storage space and a Contract System awakening at the same time.
While everyone else was still delivering takeout, he had already emptied half of Jiangcheng. While others froze to death in the streets, hot pot bubbled away inside his fortress. With temperatures plunging to minus seventy degrees and people eating one another outside, he turned an auto repair shop into a steel stronghold.
Powerful survivors mutated by pollution? He signed them up. The Icefield Empress who fell from another world? He signed her up too. People who had once been far beyond his reach now knelt before him in this life, begging for a contract.
P.S. Pure wish fulfillment from start to finish, with no angst. Revenge comes overnight, so dive right in.
