Hiruzen Sarutobi's decision

Qingyun felt a flicker of excitement when he saw the power of Red Lightning. Not only was it faster than ordinary Lightning Nature, it was also more explosive.

Its voltage was more than ten times that of ordinary Lightning Nature. Its speed also generated Lightning Fire through friction with the air, adding another layer of damage.

Ordinary Water Release could not suppress this Lightning Fire. Instead, it would conduct rapidly through the water, creating an attack over a much wider area.

Even Wind Release, which countered Lightning Release, could not fully suppress Red Lightning.

In short, once Qingyun mastered Red Lightning, his strength would soar.

With that in mind, Qingyun began flushing Red Lightning through the chakra pathways throughout his body, letting his body memorize its properties.

Only then could he develop bodily memory as he had with White Flame, skipping the compression and purification process when using it and greatly increasing the speed of his ninjutsu.

After a long while, Qingyun finally stopped when his chakra pathways could no longer withstand it and began to ache.

"Chidori Stream! Quanzhen Swordsmanship!"

Qingyun rapidly formed hand seals and shouted. Red Lightning erupted across his body. He drew the Azure Edge Sword, and a bolt of Red Lightning instantly wound around it. Streams of Sword Energy sprayed outward with the Red Lightning, slashing his surroundings into a mess.

Qingyun flickered as he abruptly activated Catching Wind and Capturing Shadows.

Whoosh!

Qingyun became a red afterimage. Sword flashes filled the area, and the red lightning's rapid friction with the air produced streaks of Lightning Fire that scattered in every direction.

Gradually, Qingyun moved faster and faster, almost as though he could teleport. He covered a hundred meters in less than a hundredth of a second, crossing over a thousand meters in the blink
