Zhao Yu, a student in the 21st century, is a first-year graduate student in the history department of Sichuan University. When he once again went to an archaeological site to observe and study, he accidentally touched a portrait from the Northern Song Dynasty. He was instantly transported back to the Northern Song Dynasty and possessed (Zhao Yu). This Zhao Yu was Zhao Yu, the seventh son of Emperor Huizong of the Northern Song Dynasty, who was also the historical King of Ji. Zhao Yu, who traveled through time, used his identity to obtain his own fiefdom, and rescued his "mother" when the Jin army went south. Then he regained the lost territory, occupied the southern part of the Yellow River, and destroyed the Jin Dynasty. After unifying the country, Zhao Yu vigorously developed the navy, conquered Korea, conquered Japan, conquered Vietnam, and attacked Central Asia, realizing his dream of Greater China.
