Chen Qingshan, a drunken gambling addict, owes 300 yuan and has only three days to repay the debt or lose his ancestral home. His wife and daughter are on the verge of leaving him. At his lowest point, he ventures into the mountains to make a living and unexpectedly awakens a tenfold return system. Every mountain product, medicinal herb, and game he personally gathers or hunts is multiplied tenfold. The former gambler, once despised by everyone, turns over a new leaf. With his mountain skills and the system's help, he gathers mushrooms, hunts wild animals, searches for ginseng, and collects wild honey, gradually paying off his debts and providing for his family. Meanwhile, the bully Wang Dabiao repeatedly sabotages him by cutting off his sales channels, hiring thugs, spreading animal-repellent powder, and setting traps involving a black bear. With courage, a sense of justice, and the help of his hunting dog Heizi, Chen Qingshan overcomes every challenge.
