Aburame Tetsumaru's Divine Technique: Creation

"Cocoon Forger, if Chakra can move at infinite speed, why can't the ninjutsu I use fire that quickly?"

Orochihime suddenly raised a question, then added, "Even Lightning Release is actually nowhere near the speed of light."

Aburame Tetsumaru nodded and explained, "I've already found a clear answer to that question."

"The reason ninjutsu has a firing-speed issue isn't a problem with Chakra's speed, but a limitation imposed by the speed of the mental energy that drives Chakra."

"Any Chakra capable of casting ninjutsu is tightly bound to mental energy. It simply cannot exceed the speed at which mental energy extends."

"And most ninjutsu aren't pure, which is also a major problem."

Orochihime nodded. The vast majority of ninjutsu carried corresponding matter along with them—for example, the plasma of flames, the ionized fluid of lightning, water, earth, and other substances.

Those substances had speeds of their own as well, further slowing things down.

Of course, that was not absolute.

First, if one's control over Chakra improved, part of the Chakra could be controlled as propulsion, increasing the projectile speed of ninjutsu.

Second, lightning and flames themselves moved far faster than mental energy, which could instead result in them dragging the mental energy along and accelerating it.

The easiest way to break through the speed limit was pure, non-elemental Chakra. For instance, as long as a Rasengan remained entirely within the range covered by mental energy, it was no longer restricted by the speed of mental energy.

Under such circumstances, the speed limit no longer existed.

The Chakra within a Rasengan spun at an extremely high speed, reaching thousands or even tens of thousands of times the speed of mental-energy extension, perhaps even faster—fast enough to rub against the air and produce light and heat.

Orochihime formed a Rasengan in her own
