At the end of the Zhou Dynasty, the world was in turmoil. Chen Zhao, a modern agricultural doctor, traveled through time and became a down-and-out scholar. Living in the southern wilderness, the land is barren, the government imposes excessive taxes, and the people are miserable. Chen Zhao relied on modern agricultural knowledge to start a counterattack. He improved rice seeds, built water conservancy projects, rotated crops and fertilized crops, and planted "Golden Spike Rice" with an output of three stones per mu, which shocked the prefecture and county. After the high-yield technology was leaked, various forces began to covet it. Chen Zhao used land as a chessboard and agricultural skills as bargaining chips to develop a self-protection system among officials, bandits, and gentry. The once "Barren Hills of the Southern Barbarians" became the "Golden Harvest City", and his name also appeared in the "Nine Pillars of Founding" in the new emperor's edict. In troubled times, he used a seed to rewrite history.
