What is the name of this classic kung-fu movie?

A 80s (or 90s) classic kung-fu movie where man challenged and killed masters. Sometimes played and fought with silver flute?





One scene he fought this master that was sitting in a chair. The master was initially blocking every attack with ease with mere hand gestures (probably with just fingers). But afterward he bested and killed him.





I think the character%26#039;s name in the movie was Yu chen chu but I%26#039;m not sure.|||Circle of Iron (1978)


aka The Silent Flute


starring David Carradine (in multiple roles), Jeff Cooper ... Cord, Christopher Lee, Roddy McDowall, Eli Wallach, Anthony De Longis


IMDb synopsis:


Cord the Seeker, a young martial artist, competes for and loses the right to go on a quest for the Book of All Knowlege held by a wizard named Zetan, but he goes along the path to seek Zetan anyway. Along the way, he meets strange tests and challenges by enemies and allies, often having difficulty determining which is which.


TRIVIA:


According to a recent biography of Bruce Lee, the film was intended to be shot in 1969 with Lee playing the four roles of The Blind Man, Monkeyman, Death and Changsha, and the lead role of Cord was offered to Steve McQueen~who turned down the role after remarking that he wasn%26#039;t prepared to make Lee a star. Instead, it was offered to James Coburn. Disagreements over location shooting (Lee preferred India) led the film to be abandoned until after his death when the rights were acquired by Carradine. Originally, karate champion Joe Lewis was offered the role of Cord but declined as he was unwilling to work with Carradine. Jeff Cooper, a friend of Carradine, finally took the part and Lewis ended up supervising the reshooting of some of the fight scenes.





Perhaps I%26#039;m offbase here, but the flute reminded me of this movie, not to say that there aren%26#039;t a number of martial arts films involving a flute. I%26#039;ll look around, as I don%26#039;t recall anyone by that name in this movie.
