Su Can (played by Zhao Wenzhuo), once the first fierce general of the Qing Dynasty, abandoned his bright future and returned to his hometown. He wanted to study martial arts and establish a new generation. He and his wife Yuan Ying (played by Zhou Xun) and son will never be separated from each other and enjoy the family life. Unexpectedly, because of the grudges of the previous generation, his righteous brother Yuan Lie (played by Andy On) practiced magic, killed Su's father, and abducted Su Can's wife and children. In the battle on the riverside, Su Can was defeated. When his life was at stake, his wife sacrificed herself to save him. Later, he met Yu Dajie (played by Michelle Yeoh), a master who lived in seclusion in the mountains and tasted all kinds of herbs, and the two were able to save their lives. Su Can was discouraged by the rupture of the tendons in his right arm. He was drunk all day to escape reality. With the careful care and encouragement of his wife, Su Can finally cheered up. Su Can fought with Yuan Lie again to avenge his previous shame, but because of his impulsiveness, he failed to rescue Yuan Ying who was buried underground by Yuan Lie in time. After his wife passed away, Su Can, heartbroken, wandered to the Sino-Russian border with his son. At this time, Su Can was like a beggar. After getting drunk, he met the "Martial God" (played by Jay Chou) who had once sparred with him in a fantasy. During the fight with the Martial God, he realized a set of boxing techniques that can show the exquisite martial arts while drunk - drunken boxing. Faced with the humiliation of his compatriots and the danger of his friends and son, Su Can stepped forward and fought a fierce battle with the Russian strongman, and finally defeated the enemy with drunken boxing.
