Shen Yan, a top student in the Department of Modern Finance, traveled to the middle of the fictional "Jing Dynasty" due to an accident. It was a severe drought in the Huanghuai River Basin, and the land was bare for thousands of miles, and people died of hunger everywhere. He became "Shen Yan", a poor scholar who was on the verge of death. He was penniless and only had the modern business knowledge and the understanding of historical laws in his mind. In a desperate situation, he saw clearly that "famine is business opportunity", used the imperial examination as a springboard to obtain identity and resources, and then relied on his advanced business philosophy, from reselling grain to building a cross-regional business network, and eventually became the leading wealthy businessman in the Jing Dynasty. While saving people from fire and water, he was also struggling in the whirlpool of power and wealth.
