After leaving the barbecue restaurant, Uchiha Kiyoshi could hardly wait to get home and experience the effects of the Body Nourishment Technique.
He had finally reached the point where he could test the Body Nourishment Technique, yet so much had happened in between.
First, he had gotten so absorbed in reading that he lost half an hour. Then he had been invited to a group meal, which took another hour or so. Uchiha Kiyoshi truly could not wait any longer and hurried home.
Meanwhile, after Uchiha Kiyoshi left, Tsunade curiously asked Orochimaru why he had suddenly become interested in him.
To her surprise, Orochimaru did not answer directly and instead asked, "What do you think of Uchiha Kiyoshi? Don't you find him interesting?"
Tsunade thought about it, realized she could not understand Orochimaru's way of thinking, and gave up.
Still, speaking of Uchiha Kiyoshi, she thought rather highly of him. However, he was Uchiha Clan after all, so there was not much she could say.
Back home, Uchiha Kiyoshi did not do anything else and went straight to the study.
After adjusting himself, Uchiha Kiyoshi began testing the Body Nourishment Technique.
After a month of effort, Uchiha Kiyoshi had already roughly perfected the Body Nourishment Technique. It could use Physical Energy broken down from Chakra to nourish every cell in the body, making up for the losses suffered by cells during Chakra extraction. At the same time, it could slightly strengthen the body and improve one's physical condition.
Perhaps it could even increase Uchiha Kiyoshi's Chakra reserves.
The increase in Chakra reserves here referred to an increase in the ratio of Chakra one possessed compared with an ordinary person.
Or rather, compared to the maximum amount of Chakra Uchiha Kiyoshi could have at the same point in time without using the Body Nourishment Technique, using it would raise that upper limit somewhat.
It was equivalent to his physique moving closer to that of an Uzumaki Clan ninja, allowing him to possess more Chakra than others at the same stage.
There was also a difference involved. The depletion caused by cells extracting 1 card of Chakra did not actually require 1 full card to replenish. For example, the Physical Energy broken down from 0.4 cards of Chakra could make up for that loss. That meant the remaining 0.6 cards of Chakra were pure profit.
After all, work had to turn a profit. Otherwise, would that not mean working at a loss? Wasn't cellular depletion caused by the process of extracting Physical Energy from food? If Physical Energy could not make up for the cells' losses, why would cells possess such a function? It should have been eliminated during evolution. Not only did it have to cover the loss, it had to make a profit as well. Otherwise, it still would have been eliminated.
Putting those thoughts aside, Uchiha Kiyoshi calmed himself, sat cross-legged on the floor, and adjusted his breathing.
Sensing the Chakra in his body, Uchiha Kiyoshi carefully guided it through his body. Whenever it reached a certain area, he broke down part of the Chakra and dispersed the resulting Physical Energy on the spot to nourish the cells there.
A full half hour later, Uchiha Kiyoshi had finally nourished every cell in his body once. He called this process one Circulation Cycle.
The first time had the best results. Uchiha Kiyoshi continued extracting Chakra while using the Body Nourishment Technique. After completing four full Circulation Cycles, he felt that further nourishment would no longer improve his cells, and only then did he stop.
The barbecue he had eaten that night had not gone to waste. At the very least, he had enough energy while extracting Chakra.
Moreover, Uchiha Kiyoshi guessed that once he began formally practicing the Body Nourishment Technique, his appetite would definitely increase drastically.
When practicing the Body Nourishment Technique, he would not perform only one Circulation Cycle.
For example, he might originally extract 10 cards of Chakra, at which point his cells would be depleted to their limit and unable to extract any more. At that time, 4 cards of Chakra used in the Body Nourishment Technique could make up for the cellular depletion from that extraction process. For convenience's sake, he could directly use all 10 cards of Chakra to nourish his body. Then, not only would his cells recover, but they would also be nourished and become more vigorous. At that point, he could extract Chakra again and repeat the process until his cells reached their nourishment limit—until they were "full" and needed to digest. Then he would extract Chakra one last time, use 4 cards to make up for that final depletion, and the remaining 6 cards would become his normal amount of Chakra afterward.
Perhaps Uchiha Kiyoshi would need to undergo such a process once every day in the future. Naturally, he would need to eat more to provide his cells with the nutrients needed to extract Chakra.
However, all of that required further observation. He needed to see when the cells could finish digesting, or rather, there was no need to wait until digestion was complete. As long as they could withstand nourishment again, he could use the Body Nourishment Technique.
What Uchiha Kiyoshi needed to do was determine the optimal interval. Whichever option offered the best value, he would choose that one.
After completing four Circulation Cycles, Uchiha Kiyoshi was mentally exhausted, but the sensation coming from his body was completely different.
It was like the feeling his little finger had given him last time. His body, which had long been in a state of depletion, seemed to have received nourishment. It frantically absorbed Physical Energy and sent wave after wave of pleasure through him.
The pleasure rising from the depths of his heart made Uchiha Kiyoshi unable to stop.
"I can't take it. This process is way too addictive. So this is what cultivation is supposed to feel like."
However, Uchiha Kiyoshi quickly came to his senses, breaking out in a cold sweat.
"Was that what they call going astray in cultivation?"
Uchiha Kiyoshi had nearly become immersed in the pleasure of his body improving. Fortunately, as a ninja, his willpower was still strong enough for him to snap out of it in time.
"So going astray in cultivation isn't making a mistake while training, but being unable to control one's own power and losing oneself?"
Uchiha Kiyoshi secretly warned himself. He had been careless this time. In the future, he had to be cautious and not become too carried away.
After reminding himself, Uchiha Kiyoshi used the lightness in his body to resist his mental exhaustion and continued studying the effects of the Body Nourishment Technique.
First of all, his physical condition had improved by a large margin. Uchiha Kiyoshi felt that in a contest of pure physical ability, he could now take on two of his former selves.
Beyond the improvement in physical condition, there was an indescribable sensation. His entire body felt full and complete. Whether in terms of reactions or anything else, Uchiha Kiyoshi could feel the difference.
The most obvious change, however, was in his Chakra reserves.
While using the Body Nourishment Technique, Uchiha Kiyoshi had completely let go for the first time while extracting Chakra, reaching 6.8 cards. Yet after this round of Body Nourishment Technique training, even after deducting the Chakra he had used in the final round to replenish cellular depletion, he still had 5.7 cards remaining!
If not for that portion of Chakra being consumed, Uchiha Kiyoshi's maximum Chakra reserves would have reached 7.4 cards! In just one session, they had increased by 0.6 cards, roughly a ten percent increase!
However, it would probably slow down in the future.
Uchiha Kiyoshi was filled with joy. The Body Nourishment Technique had finally entered actual practice, and its effects were quite good. All that remained was to persist every day.
Name: Uchiha Kiyoshi (Six years old) Chakra: 5.7 cards/5.7 cards (7.4 cards) Chakra Nature: Fire Release, Water Release, Earth Release Omitted
Early the next morning, Uchiha Kiyoshi was overjoyed as he looked at his panel. The Chakra he could command had jumped directly from a little over 3 cards to 5.7 cards—more than half again as much. Many forms of training could now be carried out.
Of course, his Chakra control had changed as well. The smallest amount of Chakra Uchiha Kiyoshi could now control had become 0.1 cards, while the amount he could control freely was only 1 card.
Uchiha Kiyoshi could foresee that as his Chakra grew in the future, he might only need to keep training his control over 1 card of Chakra for his Chakra control to improve rapidly.
With every cell in his body nourished, his eyes naturally benefited as well.
After carefully sensing them today, Uchiha Kiyoshi discovered that his eyes had already begun showing certain signs.
Signs of awakening his eyes!
Perhaps yesterday's Body Nourishment Technique had stimulated the tissues in his eyes that produced special Chakra? Or perhaps his emotions had been too intense, causing signs of awakening to appear?
In any case, Uchiha Kiyoshi firmly suppressed the urge to awaken his eyes.
According to his plan, now was not a good time to awaken them.
Uchiha Kiyoshi did not want to become a tool of the Sharingan. Only once he possessed the strength to control the Sharingan would he consider awakening it. That way, he could fully bring out the abilities of every stage of the Sharingan.
In the original story, after Uchiha Shisui obtained the Mangekyō, he relied on it too much and trusted the Mangekyō Sharingan too greatly. When facing Danzo, his carelessness led to one of his eyes being taken.
Yet at that moment, Uchiha Shisui did not think of escaping. Instead, he used one Mangekyō to activate Susanoo. Yes, you were powerful enough to use Susanoo with one eye, but what was the point? Would Danzo feel any pain over the deaths of those Root ninja? No!
He could clearly have escaped with his masterful Body Flicker Jutsu, yet he exhausted himself to such a state. It was simply far too impulsive.
Even if your heart had died and you only wanted to leave your final words to Itachi before helping him awaken the Mangekyō, you still should have tried to stay rational. You had to escape first, didn't you?
What if, after using Susanoo, your body was too depleted to escape the pursuit of the Root ninja? You were lucky they did not catch you. Otherwise, it would have been a tragedy.
And then there was Uchiha Itachi. After awakening the Mangekyō, his progress in other areas seemed to stagnate as well. You had learned the C-rank Fireball Jutsu in a single try. With that level of talent, even without the Sharingan, you would have steadily reached Kage-level.
But what did Itachi do later on? Even with the bodily enhancements gained after awakening the Mangekyō, he only barely possessed Kage-level strength. That was wasted potential too.
Do not say the Mangekyō overtaxed his body. That was also because he had been deceived by the Mangekyō's power. Otherwise, he would not have relied on it so heavily.
His talent in Ninjutsu was no weaker than his talent with the Sharingan. In other words, if he had trained seriously, his strength would have been no weaker than that Mangekyō, which even damaged his body.
Of course, that was without activating Susanoo.
But that was a trump card for preserving one's life, something that should not be used unless absolutely necessary. It could not be counted as regular combat strength. At least not before obtaining the Eternal Eye.
So one could not become a slave to the Sharingan. One had to control it and make it serve oneself completely.
But could Uchiha Itachi and Shisui truly have failed to understand this principle? Yet once someone possessed great power, they would inevitably want to use it. Gradually, they would become addicted and no longer be able to control themselves.
Therefore, Uchiha Kiyoshi would not awaken the Sharingan now.
Normally speaking, the Single Tomoe Sharingan corresponded to the strength of a Chunin.
As long as one awakened the Single Tomoe Sharingan, one could reach Chunin-level strength in a short period.
The Two-Tomoe Sharingan corresponded to two levels: Elite Chunin and Special Jonin.
The Three-Tomoe Sharingan corresponded to the strength of a Jonin through an Elite Jonin.
Moreover, with the extensive experience the Uchiha Clan had accumulated through experimentation, mastering the Sharingan was quite fast. As long as one awakened the corresponding stage of the Sharingan, mastering that stage would not be difficult.
The strength brought by the Sharingan was forced upon its user. Even a Genin, once they awakened the Sharingan, could quickly gain the corresponding strength as long as they could master and adapt to it.
But Uchiha Kiyoshi did not want to be controlled by the Sharingan's power. He could only awaken his eyes after possessing enough strength. That way, the strength granted by the Sharingan would not cause him to lose himself.
A Chunin paired with a Single Tomoe Sharingan could not only control the Sharingan's power, but could also perfectly unleash strength comparable to an Elite Chunin. That was the proper way to use the Sharingan.
Those ordinary Uchiha Clan members all developed this way. Of course, their talent was lacking and they awakened their eyes late, so by then their strength was already sufficient. As a result, they were not greatly affected.
There was another type: those influenced by the Sharingan who later raised their own strength through long-term training and eventually mastered the Sharingan. However, such ninja had already been affected by the Sharingan, and their hearts had changed. Their rationality carried a streak of madness. That was why the Uchiha Clan was said to be mad.
The Uchiha Clan's ninja were nothing more than these two types, perhaps with some still transitioning through the second type.
That was right, only those two types. Before awakening the Mangekyō, the Sharingan consumed Chakra and imposed very little strain on the body. It provided more enhancement than burden, so even if one frequently relied on it, one could still train until one mastered the Sharingan.
But the problem was that Uchiha Kiyoshi did not want to be influenced by the Sharingan, so he naturally abandoned the second path. Only the first remained.
Moreover, because he did not know what stage his Sharingan would be when he awakened it—whether Single Tomoe or Two Tomoe—Uchiha Kiyoshi could only consider awakening his eyes once he possessed the strength of an Elite Chunin or even a Special Jonin. (Don't worry, it will happen soon, before Chapter 100. And after that, there will be a period of rapid strength growth.)
After suppressing the signs of awakening, Uchiha Kiyoshi relaxed.
After doing some simple training, Uchiha Kiyoshi made himself breakfast and a lunchbox for noon. Once he finished breakfast, he happily headed off to school.
