Surviving the Mutant Apocalypse With a Ten‑Thousand‑Fold Return System

Sean Gray died a miserable death in the brutal mutant apocalypse. After years of suffering, betrayal, and watching everyone he cared about fall, he gets a second chance: reborn right before the end-of-the-world catastrophe strikes. He awakens the overpowered Ten-Thousand-Fold Return System. Every gift he gives, every act of help toward the women around him, returns ten-thousand-fold. Supplies, high-tier weapons, fierce superpowers, and rare resources pour into his hands.
Mutated beasts roam the broken city. Collapsed apartment buildings become deadly hunting grounds. Danger lurks in every shadow. Armed with his strange cheat ability and memories of the future, Sean stockpiles gear, fights horrifying monsters, and builds his safe haven. Old tragedies can still be avoided. New allies join his side. But powerful mutated creatures and ruthless human survivors stand in his path.
Can Sean use his ten-thousand-fold reward power to survive the apocalypse, protect those close to him, and rewrite his terrible fate?
