In the 21st century, Murong Yuntian drowned in hatred and was reborn on the streets of Bianjing in the Northern Song Dynasty. In a shocking incident, the dragon-shaped birthmark suddenly appeared on his waist, causing the crazy beggar to exclaim "royal blood", and the people all over the street knelt in worship. What was even more surprising was that Ouyang Sheng, the powerful official who killed him in his previous life, rode up on horseback, got off his horse and knelt down, shouting "Welcome to His Majesty the Crown Prince"!
