"You fight with me already buddy, you'll just be able to do more after this!" A lack of Ki had never stopped Shu from fighting before, he'd do it regardless. At least this way though he wouldn't be nearly blowing Takeshi or anyone else up on accident, and he could properly fly during combat. Piggybacking someone during a fight after all was pretty tricky. Having no part in the training right now the older boy stood by silently, folding his arms as he waited for the lessons to commence. When asked for coconuts he handed them over readily, not too sure where Roshi was going with all of it. Overhearing the lesson he cringed slightly, not exactly thinking it was a good plan to mash the two together. He could see where the hermit was coming from, they would have to be able to control how much energy they drew out too, but it was easier said than done for sure. He would think asking them to do something a little easier, yet maybe they'd surprise him and get it down. Or... Maybe not. It hardly took but a moment for Shu to use too much energy, popping the coconut and covering himself in bits and juices from the fruit. T'charrl... He made something grow from it? How the heck did that even work?

Roshi had barely turned around by the time Shu's coconut shattered, whipping back and looking at the young Saiyan surprised. "Heh... Well you've got plenty of energy, Shu! Gotta work on using too much though!" the hermit chided gently, looking then to T'charrl to see how he had done. Like Takeshi the old man was awfully confused seeing the plant having sprouted, his brow furrowing as he came over to inspect it. "Well I'll be damned... How did you do that...?" Poking and tugging at the leaves Roshi was surprised that the plant was secure and pretty well grown despite having literally appeared out of thin air. Weird... It was like it had been growing for weeks and yet it had been a matter of seconds. Taking the coconut from T'charrl he set it on the beach, giving it a final funny look as he rubbed at his beard. He never had a student who could grow plants before, this was going to be tricky. Maybe a different lesson would be in order. "Eh... Perhaps working on just channeling your Ki is a good idea. Don't want you blowing any more coconuts up... Ehehe... Or my house."

"Right... Well scrap that idea for now! We'll take it easier, no reason to rush after all!" Hopefully the boys didn't mind a little mind-numbingly slow training, but it was necessary so they could better control their powers. Taking the towel from around his neck Roshi tossed it over to Shu to clean himself up, folding his hands behind his back. "We'll try just focusing your energy in certain spots for now, how's that? Let's find out if you can direct your Ki to different points on your body." After all, every single use of Ki, whether it be flight, sensing, or something like a Kamehameha was all a result of carefully regulated, released energy. Chuckling under his breath Roshi lifted one hand, his palm facing up and his fingers slightly curled to make a cup. With a bit of effort he gathered Ki into the palm of his hand, forming a small orb of energy. "Ah... First things first, you boys try to direct your energy. I want you to start from the center like before and this time make it move to each point. Go from your chest to your legs, then to your arms, your head and back again. You'll need to be careful not to release it, the trick here is to know how to move it without expending any power." Letting the orb vanish the old man smiled, again getting a gleam on his sunglasses as he took a few cautionary steps to the side. "Start whenever you're ready!"
