Owen's day has been incredibly unlucky. First, he was hit by an ambulance, then Death came knocking, and finally, he was resurrected as an undead in an ancient power struggle between demigods.

His original heart location is now a time bomb. This bomb grants him immense power, but it also constantly drains his life essence. Once his essence is depleted, he will be completely consumed by the bloodthirsty evil power within his mind. Fortunately, he can restore his life essence through boxing. Currently, the undead army roams the earth, its numbers ever-growing, and Owen's prey is countless.

Owen will be caught in a relentless storm of battle, fighting to the death against endless undead remains, gigantic flesh monsters, headless flying spirits, and even mysterious creatures from beyond time. At the same time, he will try his best to avoid the tragic fate of becoming a walking corpse.
