Bai Fuguo (Jiang David), Wang Jingguo (Xu Shaoqiang) and Wu Anguo (Liu Songren) are the brothers of the wrong sword master of the Wulin gang. Wang Jingguo and Bai Fuguo are defeated in the struggle for the position of master, so they break away from the wrong sword hall and create their own sword club for seven years. Seven years later, Wang Jingguo made a comeback, won the life-betting battle with Bai Fuguo and took the latter's young son away. Wang Ning (Wu Xingguo), the son of Bai Fuguo, grew up in an one-size-fits-all meeting and had a strong friendship with Xiaolian (Yang Caini) and Ajie (Gao Jie). Wang Jingguo ordered his adopted son Wang Ning to go north to seek revenge against Bai Fuguo, the enemy of killing his father, and at the same time courted Wu'an to seize the wrong Jian Tang. Bai and Wang father and son met but did not recognize each other. Bai Fuguo felt lonely and gave up his life. Wang Ning, who was devastated to learn the truth, chose to wander around the world with Xiaolian, but he finally had to meet with the sword of Ah Jie and his adoptive father, who were once closest to him.
