Lin Fu, a graduate student in the Department of Modern History, accidentally traveled to Yongqiu County in the late Tang Dynasty and became a dying beggar. At that time, the Huangchao Uprising swept across the Central Plains, the vassal towns were separated, and the people were in dire straits. The once glorious Tang Dynasty had become a hell on earth. Lin Fu, who is known as "Aqi", relies on modern knowledge and prediction of the direction of history, starting from grabbing a piece of corn to survive, making friends with Cao Mang, gathering people's hearts, and accumulating strength. He had seen the tragic situation of people dying of hunger and the tyranny of feudal towns, and finally raised a banner in troubled times.
