At the end of the Southern Song Dynasty, the Jin invaders attacked, and corrupt officials dominated the court. Two righteous commoners, Guo Xiaotian and Yang Tiexin, betrothed their unborn children, but both families later suffered at the hands of Jin soldiers. Qiu Chuji, a Taoist from the Quanzhen School, made a bet with the Seven Freaks of Jiangnan: they would separately find the descendants of Yang and Guo and teach them martial arts, with a martial duel set for eighteen years later at the Zuixian Restaurant.
