The Supreme Overlord of the Fantasy Tang Dynasty

Traveling through the Tang Dynasty with the system, I thought that literature could bring peace to the world with pen, and martial arts could ride horses to determine the world! However... This is a completely different Datang! This is actually a fantasy version of the Tang Dynasty. Here, almost everyone has his or her own guardian spirit. At the same time, there was not only one powerful dynasty, the Tang Dynasty, but the Nanfo Dynasty, the Roman Dynasty, the Mongol Dynasty... The three dynasties and the Tang Dynasty were collectively called the Four Dynasties. Four major dynasties sit on this continent, and countless small countries around it are struggling to survive... And he traveled through time and became the Tang Dynasty, the third son of Taizong Li Shimin, King Wu Li Ke! At the same time, after traveling through time, he awakened a system called: The Strongest Guardian Spirit... Everything started with the prince's frame-up...
