Datang: the Days of Competing with the People for Hegemony

In the last years of the Sui Dynasty, Yang Guang conquered Goguryeo three times in a row, but could not make any achievements. The people were unbearable and heroes suddenly emerged, and the four great nobles also looked covetously at the Yang family. At this time, Kou Zhong, a good boy from the 21st century, came through time with the system. The system only has four simple words: "Martial Arts Supreme". In this turbulent era when aristocratic families are behaving like monsters, Koo Zhong discovered sadly that everyone in the world is passing on your secrets, and I pass on mine, leaving unknown people with no way to learn from them. Kou Zhong was very angry. Should I use my talent to learn how to crush rocks from my chest? The world is uncertain, and Turks, Goguryeo, and Fusang are all watching the war in the entire Central Plains. According to the script, Datang's surname will eventually be Li. But now that I, Kou Zhong, am here, you, the barbarian Li Shimin, should just let this great country go. This novel and its characters are purely fictitious.
