Retired veteran Li Shuanzi marries the distressed Su Qingwan as his wife. Faced with a bully forcing debt collection and his family's desperate livelihood, he resolutely takes up a gun and charges into the Changbai Mountain forest sea. Relying on hard-core military skills and the veteran head hunter's secret transmission, he starts from hunting flying birds and snow hares, then fiercely battles a four-hundred-jin wild boar king, uses his gun to challenge cruel wolf packs, and leads his whole family to build a magnificent red-brick large tile house. Facing the covetousness and encirclement of overseas poaching ruffians, Shuanzi single-handedly turns the tide, protects his wife and young sister-in-law safely, becomes famous across the province, and finally becomes the number one snowfield hunting king dominating one side!
