Lu Chen, an inheritor of Bajiquan, remains committed to his family's traditional martial arts school. To reverse the decline of traditional martial arts, he travels to Shanghai to compete, defeating foreign fighting experts with genuine skill and shattering the prejudice that traditional martial arts are merely flashy showmanship. He returns to Baihua Alley in Yanjing, resists the temptations of capital and obstacles within the industry, and reopens the Bajiquan headquarters, sealed for seventy years. He insists on affordable instruction and teaching martial arts for public welfare. Ultimately, he competes on the international stage and wins the championship, bringing Chinese martial arts to the world and carrying forward the unyielding national spirit of his predecessors.
