Yang Chaodong returns to his hometown to grow medicinal herbs, but Zhao Jinkuang, the owner of an illegal private mine, destroys his farmland through unlawful mining and leaves his father disabled. Whenever Yang demands compensation, Zhao shirks responsibility by blaming natural disasters. Yang legally builds water conservancy facilities on his own land and exploits the safety hazards caused by Zhao's illegal operations, triggering a series of collapses at the mine. Later, Li Cheng of a metallurgical group abuses his power to force his way onto a private road, ignores the warning signs, and crushes an underground reservoir, suffering enormous losses. In the end, the mine owner and corporate executive face the consequences of their own actions, while Yang protects his terraced fields and continues his medicinal herb business in peace.
