Another fantasy tale from the forbidden Chinese text, 'Ming Dynasty'. A sexually overactive squire wishes his young daughter, Yau, to retain her honour when she goes away to study. He disguises her as a boy, and fits her with a special chastity device, but she falls in love with a handsome swordsman who is in pursuit of the evil Mirage Lady. The Mirage Lady can drain her enemies' power by seducing them, and has married the squire's dim-witted son. It is now up to Yau, the swordsman and fellow student Fa Tau (who possesses a mechanical penis) to defeat the Mirage Lady.
