Ye Wuya, a nine-time full-contact fighting champion of Longguo, was blackmailed by gambling den owner Wu De before the final match against Japanese fighter Yamamoto Taro. Threatened with the lives of his wife and daughter, he was forced to forfeit the match to keep his family safe. Overnight, the national hero was branded a traitor and condemned by the public. He went into hiding under an alias and worked as an ordinary cleaner to secretly watch over his loved ones. Later, he crippled the arrogant Yamamoto Taro in retaliation but accidentally lost a jade pendant, provoking relentless revenge from Wu De. Fifteen years later, his daughter Ye Rou grew up. Haunted by the stigma of being “the traitor’s daughter” since childhood, she resolved to win glory for her country with her fists and clear her family’s name. She challenged the arrogant school bully Liu Zhihao on the campus arena. On the verge of defeat, Ye Wuya secretly guided her with Bajiquan techniques, helping her turn the tables. However, his subtle move exposed his identity, costing her the competition qualification. Determined to secure the last spot for the Martial Arts Tournament, Ye Rou ventured into underground illegal fights, where she was brutally beaten by the reigning underground champion known as “The Madman.” Watching his daughter hover between life and death, Ye Wuya could no longer hold back. He unleashed his peerless martial arts in public, overwhelming the entire arena with Bajiquan and defeating the underground champion with a single strike. His true identity was fully revealed. His old foe Wu De and the fully recovered Yamamoto Taro showed up to provoke him. Amid the fierce battle, Ye Wuya comprehended “Dragon’s Repentance,” the long-lost eighth stance of Bajiquan, and severely wounded Yamamoto Taro. He then learned that Yamamoto Yan, Taro’s elder brother, was the true top martial artist of Japan. To rescue Ye Rou, who had been abducted by Wu De, Ye Wuya ventured alone into Ningguta, a stronghold occupied by Japanese forces. Fighting his way through countless enemies, he discovered that the guardian of the eighth tower was none other than his long-missing master, who had been drugged and controlled. His master sacrificed himself to pave the way for him. Meanwhile, Ye Rou was possessed by the cursed blade Hirumaro, nearly driving father and daughter to fight each other. With great pain, Ye Wuya shattered the evil sword. Amid the raging flames of Ningguta, the rift between father and daughter was finally mended. After going through countless life-or-death trials, Ye Rou came to understand her father’s fifteen years of forbearance and suffering. In the end, father and daughter fought side by side in the grand Martial Arts Tournament. Donning his old championship gloves, Ye Wuya unleashed the ultimate essence of Bajiquan and defeated Yamamoto Yan.
