Su Chu shook his head hurriedly, "I don't know how to do it yet."

"Martial arts can't be learned solely by rote; there are tricks to it. You need to make every muscle in your body move, know how to apply force, exert force, and borrow force; all of these have their own principles."

Su Xinyi revealed some secrets to them, but the two brothers only partially understood. Su Xinyi showed them her arm and explained how she used her strength to throw the knife.
