Sui Dominates the World

Who will wake up first from the big dream? I know myself all my life. I had enough sleep in the spring in the thatched cottage, and the sun was getting late outside the window. A modern college student who knows history, can write, and is erudite traveled to the Sui Dynasty and became the eldest son of Emperor Wen of the Sui Dynasty, Prince Yang Yong, the older brother of Emperor Yang Guang of the Sui Dynasty in history. Historically, Yang Yong was a loser who was deported, deposed and killed by Yang Guang's conspiracy. As a time traveler, how can he gain a foothold in this turbulent and strange era? How to fight wits and courage with Yang Guang and other enemies? Knowing the outcome of history, can he change his destiny? Can it change the course of history? Will the Sui Dynasty still perish? Can Li Yuan and Li Shimin still become historical figures? Will there still be a Tang Dynasty in history? Everything is in "Sui Hegemony".
