Qin Zhenyuan, commander of the Northern War Zone in the apocalypse, sacrifices himself by self-detonation for his country, only to be reborn as a snow wolf in the Linyuan Mountains and awaken the Absolute Plunder System. Relying on his combat prowess from his previous life and his evolutionary abilities, he fights mutated giant beasts, protects human scientific expedition teams, slays Frost Bears and Bone Ice Dragons above his level, and evolves into the mythic-grade Winter Calamity Heavenly Wolf. Protecting humanity in a wolf's body, he cuts down the abyss and suppresses beast hordes, becoming an immortal legend of the Northern Realm—the Wolf God.
