"But-!? H-How!?!" Roshi questioned the two demons, even he would have had trouble moving such a large boulder. A lot of trouble. Master Roshi went back to a calm composure, as he sat down and sighed. "Kiro, Akita!" He called for them, as he pushed his glasses back up to his face with his finger. "Come here and have a seat." He calmly asked of them.
"Is this the first step in learning the mighty kamehameha wave, Master Roshi?" Kiro asked curiously, as he took a seat on the grass, next to his old master. Excited for what the man had to say.
Once both students were situated, Roshi began to explain. "You see, kids. Fighting is just an expression of your power, you can't expect a newborn baby to cut your grass, now can you!? First he has to grow up, gain the strength to do such feats, and then he'll be expected to do such things. The whole point of our turtle hermit training is to get your flabby bodies into superhuman condition, and once you find yourself at that level, things like the 'kamehameha wave' will become easy for you to copy and master. It may have taken me several decades, but who knows!" Roshi laughed nervously, as he rubbed the back of his head. "Maybe you kids will be able to do something like that in time for the tournament!" Roshi had no doubt that if they kept things up, they'd find themselves well prepared for the tournament. Mastering such a difficult technique at their level of strength, however, he just couldn't see it happening.
"What!? You said if we moved the rock, which we did, you'd teach us some techniques!" Kiro complained, now standing upright, red with anger. To think they spent all this time gaining the strength to move the rock for nothing! 'He's nothing but a dirty liar!' Kiro thought to himself.
"Fine! You wanna learn something kid!?" Roshi angrily shouted, as he shot up. Roshi put up both his hands, as if he were blocking from some invisible opponent. It was dead silent for a moment or two, as it seemed Roshi was preparing for a devastating attack, his eyes fixated on the invisible target in front of him, clearly very concentrated. "Ha!" He exclaimed, as he threw out his right fist, simultaneously pivoting his foot, as he turned into it. Master Roshi went back to his usual relaxed stance, as he pushed his glasses back on his face once more. "That's called a punch." He informed, as if it were alien to everyone but himself. "Tomorrow I'll teach you a kick." He assured them, nodding in agreement to himself, as he continued on the trail. Clearly not too keen on teaching anything past that.
