Everyone knows Yang Jian, who was a strict wife. When a history professor also named Yang was buried, he suddenly traveled back to the Sui Dynasty and became the founding emperor.
Yang Jian said that fortunately he has not even been in a relationship and still understands history. If I just change history like this, will I still be a star?
Fortunately, in history, Yang Jian was a "son who swore no different lives", which made the professor from the 21st century think it was pretty good.
