In the late 1980s, in Qingshan Village, Lu Zheng is forced by his parents to quit school and give his place to his younger brother, Lu Lei. The 10,000 yuan he painstakingly saved over six years for his wedding is stolen and used to pay for Lu Lei's marriage to Qian Meifeng. Furious, Lu Zheng separates from his family. With the help of a copper token inherited from his maternal grandfather that reveals the secrets of the mountains, he ventures into the mountains with Zhao Tiezhu and Sun Xiaoman to gather wild produce and build a fortune. He gives Shen Xiuhe's family a color television, refrigerator, and washing machine, and builds them a three-story house. When Lu Lei and his wife come demanding money, he cuts ties with them. He Jianming falsely accuses him of colluding with a poaching gang, but the police confirm that Lu Zheng was actually the one who reported the poachers. Lu Zheng formally asks Shen Xiuhe's family for her hand in marriage and launches medicinal herb cultivation and fox farming projects with investment from Mr. Xu. Meanwhile, Lu Lei and his wife lose their entire fortune in a fraudulent nutria-farming scheme. They kneel and beg Lu Zheng to take them in, but he refuses. After sharing the profits, he earns the villagers' respect, and he and Shen Xiuhe finally get married.
