In the seventh year of Sui Dynasty, Emperor Yang failed in his three expeditions to Goguryeo, and civil upheavals broke out all over the country. Yang Yan, a doctoral student in the Department of Modern History, accidentally traveled through time and became Yang Zhao (the same name as Prince Yuande, who died young) from a branch of the Sui Dynasty clan. He discovered that this clan son who was recorded as "frail and died young" in history books actually had amazing talents. Relying on his foresight of the chaos at the end of the Sui Dynasty, Yang Zhao aimed to "revitalize the Great Sui Dynasty". While using his clan status to make friends with the Guanlong nobles, he secretly cultivated forces from poor families. When he discovers that Yang Kung is actually a time traveler (originally an archaeologist) and intends to usurp the throne, the collision of two modern people's ideas will rewrite the pattern of war in the late Sui Dynasty - is it to continue the tyranny of Gou Zuo, or to create a new Sui Dynasty?
