In his past life, Cheng Yuanshan was addicted to gambling, ruining his family fortune, and during the years of famine, his wife, daughter, and sister-in-law all died tragically. Reborn back to 1982, his ancestral beast bone whistle activates the Patrolling Mountain Spirit Seal, allowing him to understand the thoughts of all beasts and borrow the strength of mountain beasts. He successively enters the mountain three times to hunt and gather herbs, searches for Ganoderma lucidum to save lives, and subdues packs of leopards and wolves. Since then, he guards the forest farm, opens medicinal fields, develops the mountain goods business, exhausts all his efforts to make up for his debts, wins back his wife's trust and his daughter's closeness, and repays the debts of his past life with his whole life.
