Wanyanchen - the posthumous son of Wanyan Chenglin, Emperor Aizong of the Jin Dynasty. Because his father and country were destroyed by Kublai Khan, the founder of the Yuan Dynasty, he had to shoulder the heavy responsibility of restoring the Great Jin Kingdom.
Yanjun - the youngest son of Kublai Khan, the founder of the Yuan Dynasty. Because he was born by a maid, the emperor did not like him, so he specially fostered him in the countryside. He only gave him an empty title from King Yuan Zhao, and then ignored him, as if he had never had this son.
By chance, 19-year-old Wan Yanchen met 17-year-old Yanjun. The two hit it off and became sworn brothers.
Wanyanchen admired Yanjun's magnanimity and broad-mindedness, and decided to put aside the grudges between the Yuan and Jin dynasties, even going so far as to confront and torture the relatives of the Jin Dynasty who raised him.
With the assistance of Wan Yanchen, Yan Jun began to return to the palace and gradually gained a foothold in the court. Yan Jun's eldest brother, Crown Prince Cha Yue, and Yan Jun's second brother Yuan Xing Wang Li Feng formed a party to jointly fight against Yan Jun and Wan Yan Chen.
In the end, Yanjun and Wanyanchen overcame various difficulties and escaped to each other in the fields.
