Earth Release

Three months passed, and all three of them progressed incredibly quickly.

Whenever Orochimaru personally sparred with them, the three of them were forced to face his vicious techniques. They brought out one move after another, and their potential was pushed to its limits.

Name: Uchiha Kiyoshi (Ten years old)

Chakra: 134 Ka/134 Ka (156 Ka)

Nature Transformation: Fire Release, Earth Release (Beginner)

Ninjutsu: Earth Release: Earth-Style Wall (Simplified Version), omitted

Secret Jutsu: Omitted

Other: Fire Sealing Method, etc.

After three months of extreme training, Uchiha Kiyoshi improved faster than ever before. In just three months, his chakra reserves had doubled. The other two were about the same. Sarutobi Saku's chakra had risen to over fifty Ka as well. This was where the advantages of Uchiha Kiyoshi's Body Nourishment Technique became apparent. Under the same training intensity, both his chakra growth and his base multiplier were higher than Sarutobi Saku's. The main reason was that after being pushed to his limits each time, his Body Nourishment Technique nourished him and improved his physical condition even faster. Combined with the solid foundation and deep reserves built from over three years of training the technique, it allowed him to advance so rapidly.

Nawaki's chakra could not be measured at all. Uchiha Kiyoshi estimated chakra by sensing it unit by unit himself. As his own chakra increased, he had kept counting upward. Perhaps his counting ability had improved quite a bit, but for now, he could only accurately judge one or two hundred Ka of chakra at a time. He could still make a rough estimate of Nawaki's chakra, though. It was roughly six or seven times his own—around a thousand Ka.

Uchiha Kiyoshi had nearly shut down on the spot. With the way Nawaki trained, he still had that much chakra? It nearly made Uchiha Kiyoshi question his life. Sure enough, in the Ninja World, bloodlines were the most important thing. Nawaki's Senju Clan Sage Body already likely possessed many advantages, such as recovery ability. On top of that, he had inherited the pure Uzumaki Clan Sage Body from his grandmother, giving him an enormous amount of chakra. Even if he had not inherited it completely, it still brought him considerable benefits.

However, Uchiha Kiyoshi believed in science more than bloodlines, so he was not completely crushed by the revelation. He only dazed out for a moment before recovering. Besides, his Uchiha Clan bloodline was no slouch either.

Today, Sarutobi Saku and Nawaki were sparring nearby, while Uchiha Kiyoshi practiced Earth Release on the other side.

When it came to Earth Release Ninjutsu, Uchiha Kiyoshi truly admired Orochimaru. The Ninjutsu scroll Orochimaru had given him that day contained the training method for the B-rank Ninjutsu, Earth Style Wall. Ordinarily, Uchiha Kiyoshi did not have enough chakra to learn it. However, Orochimaru's talent for Ninjutsu was indeed exceptional. He had actually simplified the B-rank Ninjutsu so that it consumed only as much chakra as a C-rank technique—just a few dozen Ka. Once Uchiha Kiyoshi mastered this simplified version of Earth Style Wall, he could directly transition to the true technique once his chakra reserves increased.

Orochimaru's thinking at the time had been based on Uchiha Kiyoshi's fighting style. Earth Release suited him better, so he gave him an Earth Release Ninjutsu. As for Uchiha Kiyoshi's chakra affinity, Orochimaru had not considered it. At worst, he could train Earth Release first and slowly develop the affinity later. The power might be a little weaker, but it still suited Uchiha Kiyoshi's circumstances.

Orochimaru simply did not know that Uchiha Kiyoshi actually possessed an Earth affinity. Of course, even if Orochimaru had known, he would not have cared.

Three months was enough time for Uchiha Kiyoshi to learn the simplified version of Earth Style Wall. With four years of research into the principles of hand seals, he also learned Ninjutsu quickly. He had successfully cast the technique in just over half a month, and over the following two months, he became proficient with the hand seals. He could now use it in actual combat.

A week ago, after checking Uchiha Kiyoshi's training progress, Orochimaru had said nothing, but he had clearly been satisfied. Although the chakra consumption had been reduced, the difficulty was still half a level higher than a C-rank Ninjutsu.

After tossing down another Earth Release scroll, Orochimaru left.

This time, Orochimaru had given him Earth Release: Earth Spikes, a Ninjutsu that could produce earthen spikes from the ground. It was considered relatively advanced even among C-rank Ninjutsu.

Unlike when he had trained Earth Style Wall, which required him to study many unfamiliar Earth Release minor cycles, Uchiha Kiyoshi now had experience from before. The number of minor cycles he needed to compare had been greatly reduced. After a week, he had basically figured it out.

Uchiha Kiyoshi calmed himself and began forming hand seals with both hands, while focusing on mobilizing the chakra within his body.

As he formed the seals, Uchiha Kiyoshi guided the chakra through his body, completing one minor cycle after another.

After four years of researching hand seals, Uchiha Kiyoshi had roughly grasped the principles behind Ninjutsu casting. It was similar to the formulas of Sealing Jutsu. Different methods of circulating chakra within the body produced different effects, and many of the special effects of Ninjutsu were granted by specific chakra circulations.

Uchiha Kiyoshi called processes such as circulating chakra from the lower abdomen to the arm and then back minor cycles. These were the foundation of Ninjutsu casting, corresponding to Sealing Jutsu formulas. Only by completing different minor cycles in a specific order could one cast all kinds of Ninjutsu.

Uchiha Kiyoshi had summarized hundreds of such minor cycles over the past four years alone. To make them easier to remember, he planned to classify and number them. Cycles passing through the brain began with "A," while the four limbs began with "B, C, D, E" respectively. The torso was also divided into several regions. For instance, the five viscera and six bowels were represented by the English letters A, B, C, and D. If a cycle passed through two or more areas, they were arranged in sequence. For example, if it began in the lower abdomen, passed through the brain, then the heart, and finally returned, it would begin with "'AA." The apostrophe represented the lower abdomen.

As for the numbering that followed, Uchiha Kiyoshi had not arranged it randomly. Instead, he planned to number the minor cycles according to which functions he understood first as he learned Ninjutsu.

In other words, this work could only be carried out while learning a large number of Ninjutsu. It was by no means something that could be accomplished overnight. And Orochimaru happened to be one of the Ninja World's Ninjutsu users with the most techniques, surpassed only by the Professor of Ninjutsu and Senju Clan Tobirama. With Orochimaru as his teacher, was he really afraid he would not be able to learn enough Ninjutsu?

Uchiha Kiyoshi first completed a "'B" cycle, guiding chakra from his lower abdomen to the spleen, which was Earth-aligned, and then completing a cycle within the spleen without returning it to the lower abdomen. He then divided the chakra remaining in the spleen into three streams and performed three minor cycles according to "B1," "BD (left leg)3," and "BE (right leg)3." After carrying out several similar processes, aside from the chakra left in the spleen, most of the chakra was ultimately sent into his legs. Then, as he formed the final seal, he completed the "BD1" and "BE1" cycles, pouring all of his chakra into his legs.

Uchiha Kiyoshi then controlled the chakra in his legs and sent it underground, guiding it to a point five meters in front of him. With a thought from Uchiha Kiyoshi, three earthen spikes suddenly burst from the previously flat ground. Each was five centimeters thick and twenty to thirty centimeters long.

"Success!"

Uchiha Kiyoshi was thrilled as he watched the three earthen spikes emerge from the ground. Sure enough, his theory was useful. Once he had mastered the fundamentals, learning Ninjutsu became twice as effective with half the effort. As he grew more familiar with the functions of all kinds of minor cycles in the future, mastering Ninjutsu in seconds would not be a problem.

The Uchiha Clan's Sharingan probably copied Ninjutsu by imitating the opponent's chakra circulation, right?

Uchiha Kiyoshi thought of the Sharingan's copying ability. At that moment, he gained some understanding of how that copying worked.
