As Neji continued to beat the crap out of Naruto, the shadow clone hiding underground began to softly read aloud from a scroll.
This wasn't a summoning scroll, or a scroll containing forbidden techniques. As far as any ninja, from a genin to a kage would ever know, the scroll was a simple (even poorly written) fable, a childs story really. But to Naruto the scroll was something more. Something known as a manual.
The words the clone was reading now began to prickle with hidden energy, though all that the proctor could hear was a faint chanting in a foreign tongue, as the sounds of battle became muted, as if inconsequential in contrast to the importance of what was being said.
But if you weren't a ninja, if you were something else entirely, then it might have sounded something like this:
"This is a tertiary class temporal intervention, bound to sentient target Hyuga, Neji. I am calling for the degridation of localized chronological progression by a factor of .0000025 in radius +/- 1 meter of bound target from julian date XXXXXX.X2432-XXXXXX.X2447, to facilitate additional physical intervention. Supplemental energy required to ofset localized entropy is to be paid with the life energy of the caster. Parameters have been established. Knot!"
The clone promptly poofed out of existence and to the amazement of all gathered, neji just stopped. No... that wasn't quite right. His arm was still moving, if imperceptibly so, as it continued on at a snail's pace to complete its trajectory. Well really none of his body had stopped at all, he was simply moving so slowly that the only indication that he was moving was due to the normally quick speed of his strikes.
Naruto walked up to Neji and swiftly slashed Neji across the throat with a kunai. Six seconds later Neji began moving at normal speed and quickly began bleeding out.
As the match was declared in his favor, Naruto thought to himself, "Well now that I know my clones are granted the same access to the Art I guess that means I can spam some ridiculously powerful spells and power them with life sacrifice. What a fun loophole."
Yes it was a good day.
Once again Naruto was grateful that he had taken the scroll entitled "So You Want to be a More Powerful Ninja" for light reading along with the forbidden scroll when he had raided Hruizen's office.
