Ming Dynasty Juzi

A high school teacher pretends to be the grandson of a county magistrate. In order to live a good life in a feudal society, he works hard to pass the academic examination. While studying, he met and befriended the anonymous Taisun, and later found out his identity. He was afraid of being liquidated by Emperor Yongle, and when he was about to break off diplomatic relations with the Taisun, he discovered that the Taisun had traveled through time. The grandson ascended the throne as Emperor Jianwen. As Gao Jing's power became more and more powerful, Emperor Jianwen became suspicious. Gao Jing took the initiative to confess his identity as a time traveler, and found out that Emperor Jianwen was his nephew who traveled through time. After that, the two had no suspicion at all, and they complemented each other in the court and jointly created a prosperous age of civilization.
