The Knight in the White Night

The story

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.
