The bully Pan Dewang comes to collect a debt, demanding nine thousand yuan in usurious debt to take away the Jiang family's house and sister-in-law Bai Xiulan. The mountain-foraging youth Jiang Huaichuan, who is so poor he cannot even light a fire to cook, protects his sister-in-law and niece, and goes into Wangyun Mountain with a short blade to find a way out, accidentally awakening the "Ten Times Harvest System" where digging one mountain yam yields ten, and gathering one old ginseng yields ten. From monkey head mushrooms and ginseng kings to red reishi kings and rare orchids, he relies on mountain foraging to pay off the vicious debt and set up a family business, also saving wild beasts deep in the mountains and fighting down black-hearted hunting teams and poaching gangs.
