Five years ago, Lin Feng topped the martial arts rankings. On his wedding day with Liu Qing, he was ambushed by Wang Tianfang and Liu Qing, his right arm crippled and he was thrown into the river. Fortunately, Shen Qingcheng saved him. To repay her kindness, Lin Feng and Shen Qingcheng made three promises. The first two have been fulfilled, but the third remains unspoken. Over the past five years, Lin Feng has diligently trained his left arm, mastering martial arts to perfection. When he was about to leave to seek revenge, he encountered Wang Qiang forcing Shen Qingcheng to marry him, and Shen Qingcheng was betrayed by her fellow disciples. Lin Feng did not mention the third promise, intending to help Shen Qingcheng kill Wang Qiang. Shen Qingcheng held a martial arts contest to choose a husband, and Wang Qiang appeared. Lin Feng finally intervened to save her, exposing his own identity and revealing the crimes of the Wang family, including their attempt to murder Shen Qingcheng's father, Shen Tianhua. Lin Feng rescued Shen's father, avenged his father, defeated Wang Tianfang, and restored the reputation of the martial arts world.
