He stood there for a moment as she moved swiftly and placed a foot on the back on his knee. He didn't move because as soon as she moved he could tell she was not going full out. His hunch was confermed when she placed a foot on the back of his leg. Then scurried over in front of him shyly "I said I don't know much." 

He nodded and said. "Ok. You told me but i need to see it. I want you to hit me I'm not a piece of glass. Don't be timid. Be confident. " He then motioned her to come at him again. 

Nyima came at him, she used flowing motions as she punched multiple times. They were slightly clumsy and rusty and slow as she was thinking of the moves as she goes. Each punch and kick, Rayn ducked shifted spun with out moving his hands from his back. He would lift his legs once in a while to block random moves here and there. After a bit he lifted his hand to stop her by catching her last punch. He watched her as she breath was heavier now.

He then nodded and said, " Better... Waterbenders use Tai Chi, an internal style that focuses on the control of energy. It is a very soft, gentle and flowing, but devastating when mastered. You must learn to use little strength to defend yourself. Which is perfect for you because of your lack of strength... No offense. " he said with a slight smile. "With Tai Chi, you create circles to pass by attacking energy and issues their own energy outward. In short you take their energy and reverse it back onto them. While being used for combat, Tai Chi also serves as therapy for the purpose of health and longevity. "Tai Chi" literally translates into "Incredible Energy," and it earns its title. Even you, when you become a master of it can defeat the strongest attack of an earth bender with his own strength." 

He then continued " I've studied Tai Chi a little to help with my personal style. So I can teach you the basics but I've will find a water bender later."
