The master said, brushing the boy off his legs "Second of all, like I said it's a simple technique, all you have to do is..." the master said, not wanting to do the technique again to Kiro thinking he might kill him "First you do a uppercut to the chin, with a open hand, at close range, your opponent will probably grab this hand to stop the attack, that's when you use your other hand to strike your elbow, now the force of two hands is behind the one hand, and since your hand is on his chin there's no way he can dodge!" Rekin shouted, now seeing the boy looked a little confused "Here how about you try it on me." the master said, leaving himself wide open.
