"Yes, I do know some Lightning Release already." Pausing and listening intently, the act of creating lightning more efficiently was something that caused him to squint for a moment and think. How exactly could he do that? All he felt was lightning coming out of his hands after a weird feeling in his stomach. The mention of bringing it further than that caused his brow to furrow. Something clearly too advanced to do, but it was something he could do later.

The mention of vibration however caused him to perk up. He understood that concept well. "In the caves, the worms would vibrate rapidly in order to try and escape. Allow me to try."

Clesrly not understanding Sadazane weaved another series of hand seals, then stuck out his hand and began shaking it violently, clearly trying to vibrate his hand rather than work on the lightning itself.

" Lightning Release: Electromagnetic Murder."

As the technique fires off and was unchanged, the Jihibiki looked towards Sana again. Even behind the sunglasses, the Jonin could feel the gaze of disappointment from behind the sunglasses, moreso in himself than his teacher.

"That did not feel more powerful. Did I not do something correctly?"

"I... I see i need to work on my explanations a bit better. My apologies. What I meant was that lightning release chakra is just normal chakra that vibrates until it starts to bump into itself and create sparks. That's what I meant when I said you need to focus on that vibration. If you can fine tune the vibration for each jutsu that you use, you can make a jutsu more powerful than it otherwise would be normally."

"Lightning Release: Lightning Ball."

*Sana weaved hand seals absently with one hand as he created a series of lightning balls and sent them into the air before they burst into sparks. Quickly doing it again, he put more focus into it and created more spheres that moved more quickly before the burst into slightly more sparks. A quick demonstration of the difference between gaining proficiency in the element and just being able to do preform the jutsu to an acceptable degree.*

"It's like that. Eventually you can strengthen jutsu even further by using more chakra and grater amounts of chakra control, but that kinda stuff is more advanced than just getting a little bit more control over the element."

*Sana needed to improve his control over his element as well, he felt like he needed to be able to use it in more creative ways to get the most out of it possible. It was safe to say at this point he wasn't going to learn another element, so he needed to be able to use the element he did have to its fullest potential.*

Blinking slowly at the explanation and trying to piece it together in his brain, at the apology Sadazane would shake his head. "My mentor in the caves said to not apologize, merely fix the mistake. You have done so. I am glad I do not have to violently shake my hands in order to make my Ninjutsu better." 

Seeing Sana weave hand seals with one hand however caused his nonexistant eyebrows to raise. That was something interesting. Being able to perform a technique without taking up both hands would surely be useful. 

"How do you vibrate your chakra more? I do not understand anything but the basics of manipulating my chakra. It sounds as if I must simply put more energy into the attacks. Is that the correct answer?" 

Seeing Lightning Ball caused the Genin to weave handseals again, with three Lightning Balls erupting from his hand, though they merely dissipated into the air rather than bursting into sparks, indicating he was not as well versed as Sana in the element.

"It's not exactly *More* Energy as such. I suppose its hard to explain something that you've known about your entire life. I just imagine it like when you create lightning release chakra, You take some normal chakra and picture it vibrating intensely, faster and faster until it starts to bump into and collide with itself to create the electrical discharges."

*Sana raised his hand and covered it it normal chakra before doing the process he described only slowed down. It wouldn't help visually at all to see this but it seemed like visualization might help a bit. Gradually sparks started to dance across Sana's hand as he held it up.*

"Or at least that's how I've always pictured it. It might be different per person as to what helps visualize the exact process, but that was how I always pictured it. If it helps you understand it more to think of it as putting more power into it and that gets you more control then great. Whatever floats your boat. I usually relate my chakra manipulation to things that loop back to my experience with taijutsu. So I imagine vibrating chakra like intentionally clenching and un-clenching a muscle very quickly."

*Sana put down his hand and shook off the sparks, before combing the hand through his hair and watching for his enterprising young Jihibiki student's reaction to his explanation.*
