There is not just one kempo master. You have not mastered anything. If you had, you would not be asking this ridiculous question. I am going to take this whole thing as a joke. Enjoy your "mystic" nonsense. I am guessing you have never studied martial arts in your life and if you have, you only studied for a really short period of time. Therefore, you are not ready.
Why fight kempo karate master only? Try boxing walterweight world champion,mma or muay thai world champion. trust me this 3 is the hardest. But try going to their dojo and ask for challenge thats what a lot of street fighter or challenger do in bruce lee's days.
