In his past life, Li Changsheng was addicted to gambling, ruined his family, and failed his wife and daughter. Reborn back in the Northeast of the 1980s, he runs right into creditors forcing his wife and daughter to pay off debts as collateral. After waking up to reality, he fights off bullies and relies on his past-life experience to head into the mountains to hunt. From hares, roe deer, and wild boars to century-old wild ginseng and top-tier animal medicine, he gradually pays off his debts and lets his wife and daughter live a good life. As his skills come to light, he gets further entangled in the conspiracies of poachers, armed bandits, underground gold mines, and the Bai family fighting over Laolongkou. Facing the temptation of money and armed threats, Li Changsheng joins forces with Zhao Jianguo, Zhuzi, Daniu, and others to protect the mountain forests, establish a cooperative, and lead Kaoshan Tun to prosperity together.
