Convenient

Rui grew incredibly excited at this new revelation!

The reason for this was that he had inadvertently come across one of the principles of Jeet Kune Do, a martial art that Bruce Lee himself had developed. The principle of intercepting one's opponents' attacks by moving before their opponent moved.

('How do you combat something that's too fast for you to combat after it has begun? You defeat it before it begins,') Rui hadn't intended on it but had inadvertently stepped in the direction of one of Bruce Lee's principles.

After all, his technique relied on predictions to begin to move ahead of time with perfectly timed pre-programmed movements.
