"Fifth Brother, would you like to practice a few moves with me?"
Su Chu shook his head hurriedly, "I don't know how to do it yet."
"You learn it by practicing. I'll teach you how to use your strength, observe and understand the techniques, so when it's time for you to learn by yourself, it will be much easier," Su Xinyi said with a smile. "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."
As Su Xinyi spoke, she flicked her wrist, and the curved knife in her hand flew out like a gust of wind, embedding itself firmly in the target. A humming sound echoed from the blade.
Su Bei: ...
Su Chu: ...
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.
