The story must start from the blazing temple: it is said that during the reign of Kang and Yong in Qing Dynasty, the imperial court wanted to thoroughly eliminate the secret societies that fought against the Qing Dynasty and regained sight, and found that Shaolin Temple was inextricably linked with heaven and earth, so it sent troops to wipe it out. But Shaolin Temple needs a traitor to buy off Ma Ninger, a disciple of Shaolin laity who ranks seventh in martial arts.
