So long as Shu and T'charrl were both willing to learn Takeshi would more than happily teach them. What he could at any rate, he was by no means the expert when it came to Ki, but he did know more than these two. By the sounds of it they were both more than ready to go on with their lessons, even if they weren't wholly confident. "You might not be very strong yet, but give it more practice and you will be," he said, trying to be supportive. "Besides, Ki isn't the only thing you get strength from. Plenty of people can be strong without it, Ki just happens to be pretty darn handy." Which was all the more reason for them to learn it, they could certainly make use of it in the coming battles. When all their enemies would be blasting off attacks comparable to a small bomb they really should be able to counter it with their own. "Releasing it is kind of like channeling it, only you don't stop it when it reaches a certain point. Like this..." Lifting one of his arms Takeshi extended his hand, holding it flat facing the ocean. Gathering a bit of Ki right in his hand into a ball he formed a relatively small blast before releasing it, sending it soaring out over the water as it exploded some few dozen meters away. 

"You both know how to channel Ki, now you need to learn how to channel certain amounts. Since you can see Ki when it's outside, usually, you can kind of get an idea how much you're releasing." Turning back to Shu and T'charrl he held his hand, palm up, and gathered a little bit of Ki again. "Depending on how much you release and how concentrated you make the orb the stronger your blast will be. You can have something like this..." Takeshi pushed out more Ki, purposely making a rather large orb the size of a big beach ball. "Or this..." he added, shrinking it to something comparable to a basketball. It was definitely the trickiest part of their training, knowing how much to release and where. If their earlier progress said anything about these lessons though it was that they should get it fairly easily. "For starters, you two will just make little orbs. Hold your hands together like this," he kept one hand upside down and held the other over it, some 20 centimeters apart. "And form an orb between your two hands. If it helps only let energy come from one hand, then you're not putting out as much. When you make it big enough to fit in both hands stop moving your energy and concentrate on holding the ball as it is. Sound pretty easy?"

Roshi wasn't used to someone like Viral, both in regards to a Beastman and him being utterly out of it. While the hermit was all for talking to the young man he wasn't exactly sure how to approach it, seeing as he wasn't the most sociable being to begin with. Finally getting some recognition after taking a seat the old man smiled, "You don't know me, though that didn't stop you from tossing me like a coconut!" he laughed, gesturing to himself with his thumb. "The name is Roshi, I'm a pretty big deal you know. Trained Goku, his son and friends, and even these kids a bit. I happen to be quite the martial arts expert as well, heh heh." Plus he was a connoisseur of women, but considering Viral's reaction to him earlier, assuming it was over Yumi, he thought best to keep that to himself. "Anyway, what about you? I know your name is Viral, but what more is there to know? What haven't I been told yet, hm?"
