Hey. Does Anyone know or remember a kung fu movie around the late 70's or mid eighties, where three men band together to take down a ruler, by biting their fingers, mixing their blood in a bowl and then drinking it? They fought an army that used iron fists as weapons. One of the men was strong enough to bend a sheet of iron with his bare fist in a test of strength against the army master. He was a reluctant fighter, I think. In the end, one dies while the remaining kick over the name or symbol of the ruler. Good movie!
