I am having trouble trying to find this japanese or chinese movie from a few years back in the early 2000s. Basically what i remember is, is that there was like 4 or 5 warriors that specailized in a type of weapon. they were a tea and they went to this place (i think by the king or emperor or something) and they were getting killed off one by one. until the leader i think or the main character found out who it was and it was a big fight in the end. no matter what i try to look up i cant find anything close.
