During the Ming dynasty, Japan invaded China with an army equipped with guns. The union chief of the martial arts clans revealed in his deathbed that there is a rare book containing secrets that will make a person immune to gunfire. His last words sparked the clans to contend with each other to find it. Also in search of the book were the Japanese who dispatched a team of ninjas to go after the book. The imperial court also secretly intervened in this dispute. The emperor secretly dispatched a Kung fu Master and ordered him to find the book within seven days.
