More than a hundred years ago, a Chinese Shaolin martial artist named Wu Tianxing went to Japan to promote Shaolin martial arts, which provoked challenges from the four major families of the Imperial Guard in Japan. Wu Tianxing faced defeat against three families, and after a shocking battle with Chiba Benlei, the head of the Chiba clan, Chiba Benlei was defeated but, unwilling to accept this outcome, desired to fight Wu again. Wu Tianxing respected him as a true martial artist and promised Benlei that even if he died, his descendants would accept the challenge. A hundred years later, Chiba's descendants, led by Chiba Guiyi, searched for the whereabouts of Wu's descendants, constantly challenging the Shaolin schools of martial arts. Guiyi only knew to practice martial arts for revenge and did not understand the way to sustain life, leading him to beg for survival. Meanwhile, Wu's heir, Wu Daoyi, worked in the same tofu shop as his childhood friend Zihui in a fishing village. Daoyi set up a martial arts school in the courtyard of the shop, but unfortunately, over the years, only one person came to be his disciple. Before his death, Daoyi's father warned him not to resort to violence and gave him a Buddhist prayer bead, telling him to think twice before taking action.
