Yang Guo has been wandering around the world since he was young. After being taken in by the great hero Guo Jing, he became a disciple of Quanzhen Sect. However, he was bullied in Quanzhen Sect because of the mystery of his life experience. Unable to bear the torture, he changed his mind and became a disciple of Xiaolongnu by chance to learn martial arts. It happened that the foreign national master Jinlun Fawang led his people to the south and joined forces with the abandoned disciple of the Tomb Sect, Li Mochou, to seize the martial arts secrets and arms map in the tomb. Yang Guo and Xiaolongnu, who were unintentionally involved in the disputes in the world, lived and died together several times. The friendship between the master and the apprentice gradually developed into a bitter love. During this period, Yang Guo's arm was cut off and he fell off a cliff, where he met the "good teacher and helpful friend" Divine Eagle.
