Nuchiha recently learned that Kinoko, learned Shockwave, a same technique used by Nappa. It was used by lifting up your middle and index fingers, and exploding your ki around yourself, or something else. It had to be simple, really, you just had to surround a object with your ki, and explode it. Nuchiha surrounded a rock with his ki, and exploded it, and it destroyed the rock, success. . .
If Kinoko can learn it easily, then I can, I mean, it's a simple technique. . .
