The world was in chaos, with nine kingdoms fighting each other. Then the kingdoms started to fight, shaking the land of China. Liyang broke through the situation, wiped out the eight kingdoms, and achieved the trend of unification. In particular, the Beiliang cavalry of the Liyang Dynasty destroyed the six kingdoms and slaughtered the world with an invincible momentum. After Liyang was unified, Xu Xiao was crowned king and guarded the three states in the northwest. His achievements were so great that the emperor was afraid of him and wanted to marry Princess Suizhu to Xu Xiao's eldest son Xu Fengnian to control Beiliang. In order to avoid being the consort of Princess Suizhu, Xu Fengnian, who was about to reach adulthood, took off his brocade clothes and entered the world of martial arts under the arrangement of his father. Once in the world of martial arts, Xu Fengnian and his groom Lao Huang made fun of the hardship and met many people in the world of martial arts. After three years of traveling, Xu Fengnian, who had kept a low profile, washed away the dust and laughed cynically, but he was able to clear the clouds and mist and saw through the assassination plan set up by Jing'an King Zhao Heng. Xu Fengnian has never wanted to follow the life track laid by his father, and he doesn't want to take over Beiliang, because becoming the King of Beiliang means becoming a lonely man without emotions. But when Xu Fengnian was crowned in the snow, he learned that Lao Huang was killed by the master Wang Xianzhi in Wudi City, and his younger brother was forcibly taken to Longhu Mountain. The eldest sister became a victim of political marriage, and the second sister could not go home for the sake of her father's overall situation. One by one, his close relatives left him, and Xu Fengnian once again experienced the darkest moment of his life. This time, he finally made up his mind to be a completely different King of Beiliang from his father. No matter how difficult it is, he can't compromise. Xu Fengnian studied martial arts hard, went to Wudang Mountain to learn swordsmanship, and became a warrior with his innocent heart and hard work. Then he led his maid Jiang Ni, the sword fairy Li Chungang and other guards to enter the rivers and lakes again. When he entered the rivers and lakes for the second time, Xu Fengnian was full of vigor and vitality. Wherever he went, those famous martial arts families could not escape the fate of damaged reputation, chaos and even disbandment. In the eyes of outsiders, the chess pieces and hidden games that the King of Beiliang Xu Xiao had worked so hard to lay down were all ruined by the prodigal son Xu Fengnian. But it was precisely because of this that the court finally gave Xu Xiao the hereditary power with confidence. Xu Fengnian seemed to play chess according to his father's routine, but in fact he went alone in the snow, resisting the arrangement of fate, and gradually cultivated new martial arts forces such as Wudang, Jiangnan Literature, Xichu, Huishan Xuanyuan, etc. who were willing to be loyal to him. He also found out through various clues that his mother Wu Su died early in her life not because of illness, but because she was killed by the masters of Liyang and Beimang. In the snow, Xu Fengnian was alone with a knife and a grudge. He would use his body to carry the Beiliang battle flag, protect the students, safeguard peace, and protect his family, and eventually grow up to be a qualified successor to the King of Beiliang.
