Ron's eyes gleamed as he looked at his father, like a super saiyan, with an uncontrollable aura like when Goku went super saiyan for the first time the surrounding platform was destroyed rocks were floating, although no rock was floating this time it looked cool. It was reminiscent of Goku's first time going Super Saiyan no, more like Super Saiyan 2, except the energy surrounding him wasn't golden, but a crackling blue, charged with lightning chakra.
"Father, how does nature transformation work?" Ron asked. "From what I know, ninjas with stronger nature transformation can turn their chakra into elements without seals, which has various uses. Also, a stronger nature transformation leads to stronger ninjutsu."
The Third Raikage studied his son for a moment before crossing his arms. "Nature transformation is the refinement of chakra into an element. But what you're asking goes beyond the basics."
The air around him stopped crackling, exiting the lightning chakra mode as he raised a hand, his fingers flexing slightly lightning shuttling in between. "A ninja's affinity determines how easily they can convert chakra into an element, but mastery of nature transformation isn't just about affinity, as it can be gained, of course, it requires hard work, so being born with multiple type is a blessing. Nature transformation... It's about depth. Look!"
Raising his hand lightning flickered to life around the third raikage's fingers, but it wasn't ordinary lightning. The lightning energy condensed, growing more refined, louder, and brighter, and then more fluid/gaseous and quiet just like chakra, as if it had taken on a life of its own, different from normal. Its color shifted from a pure plasma blue with lightning flickering, similar to Chidori, to a gaseous/fluid state without much visible lightning.
"At the highest level, you don't need seals or gestures. The chakra itself becomes an extension of you just like breathing. That's what separates a skilled user from a true master."
Ay nodded then told Ron, "Although our clan has ninjutsu that don't require seals, like father's Hell Stab, and my Lariat, these ninjutsu are basically attached to our body, so it is easy to perform, as for long range, ninjutsu which causes chakra to separate from our body, it is better to use seals! as it easily dissipates in nature, after leaving our body!"
Listening to this Ron's ear pricked up!! But he continued listening for now.
He let the lightning dissipate and looked at Ron again. "The stronger your nature transformation, the closer you get to becoming the element itself. Stronger ninjutsu is just a result of that, not the goal. The real power is in how seamlessly you wield it, and its different uses aside from power!"
A faint smirk formed at the edge of his lips. "So, tell me, Ron what did you see?"
