Legendary Weapons of China (Chinese: 十八般武藝; pinyin: shí bā bān wǔ yì; Jyutping: sap6 baat3 bun1 mou5 ngai6, lit.

It takes place during the late Qing Dynasty when Empress Dowager Cixi dispatches her agents to various factions of the Boxer Rebellion in order to find supernatural martial artists that are invulnerable to western bullets.

As the title of the film suggests, a great variety of fights take place involving the "legendary weapons."

Although Liu Chia-liang is known for showing "real Kung-Fu" in his films, he does take some artistic license by incorporating elements of Taoist Maoshan folk magic with hand-to-hand combat.

Lei Kung no longer believes that their martial arts skills can defeat the modern weapons used by the western colonialists.

He finally admits to everyone that he is Lei Kung, and declares that he has betrayed the Yi Ho society because he does not want to see all his young students die in a futile attempt to fight foreign modern guns and cannon.

Fang, believing it to be Ti Hau, berates him as he sits down and prepares, but is then shocked when it's revealed to be Master Tieh.

Master Tieh attempts to uses his mind control techniques on Ti Hau, in order to have him effectively commit suicide, announcing that both he and Lei Kung must die.

Defeated, Master Tieh chooses to commit suicide using the same eye gouging technique on himself that he (using his mind control) tried to get Ti Hau to do.

Lei Kung dresses in ceremonial garb and arrives at a temple with Ti Hau, Fang Shao Ching, and a full set of weapons.

As combat progresses, the brothers constantly change weapons as each new choice seemingly defeats the techniques of that previously used.
