Uchiha Kiyo also knows the dangers of chakra. If too much refines it, it will damage the cells of the body, resulting in the lifespan of ninjas. Since the first refining of chakra, Uchiha Kiyo has never refined chakra with all his strength.

But it is not a solution to keep going like this. If you can't find a way, the chakra's speed of upgrading will definitely be delayed. The chakra cannot be improved, and even if you learn ninjutsu, you have to search for it. Sooner or later, you will drag yourself to death.

Uchiha Kiyoshi was also anxious and took five or six hours every day to go to the Uchiha clan’s information room, hoping to find inspiration.

However, this is not something that can be found casually. Uchiha Kiyoshi can only calm down and do his own thing every day.

In this way, half a month passed.

There are ten days left before Ninja School is about to start, and Uchiha Kiyoshi doesn't feel anything about this.

In half a month, Uchiha Kiyo's sealing speed doubled again, and he could already achieve two marks in one second, reaching the standard of learning ninjutsu.

As mentioned before, the release of ninjutsu is accomplished through the operation of chakra in the body, which requires a certain sealing speed. Otherwise, the effect of the previous seal has passed and the latter seal has not yet been formed, so how can it be successful?

Moreover, the sealing speed of Uchiha Kiyoshi mentioned here is just a simple hand speed.

Without any cooperation of chakra operation, there were only two marks in one second.

If you add chakra, you should pay attention to the rhythm between the handprints, and three seals may not be formed in two seconds!

In the original work, Uchiha Itachi has six seals in one second, which is also the case of releasing ninjutsu, which means that it is mobilized by chakra, and it is still in battle.

That's why Uchiha Itachi's six marks in one second are very strong. Otherwise, as long as he is willing to practice, any person can actually have the hand speed of six marks in one second. The difficulty is the mobilization of chakra.

In general, you must be familiar with the chakra flow during the entire ninjutsu release process, and then follow the speed of six seals in a second to run the chakra.

After the seal is formed, the flow speed of the chakra is actually certain, and of course it can be controlled by the ninja itself. The increase in the seal speed is actually accompanied by the increase in the speed of the ninja pushing the chakra.

Even with the guidance of handprints, this process is quite troublesome and it is difficult to do without day-to-day practice.

Uchiha Kiyoshi can only take the speed of sealing slowly step by step.

Recording and summarizing the chakra operation corresponding to the handprints, Uchiha Kiyo has already entered the right track and completed the recording of the impact of the twelve handprints on the operation of chakra on the lower abdomen, and other parts have also begun to be studied.

However, due to Uchiha Kiyoshi, Uchiha Kiyoshi is not particularly outstanding in chakra, so the time to allow Uchiha Kiyoshi to study every day is limited.

Then the question goes back to chakra again.

Looking at the history of ninja development, chakra is always an important factor that restricts ninja progress, so there is actually not much time left for Uchiha Kiyoshi.

Uchiha Kiyoshi also decided that if he still couldn't find a solution within three months, he would give up his original plan and do his best to refine the chakra.

Anyway, there are also some strange ninjutsu in the ninja world. At worst, you can get a new body, reincarnation of the filthy land and reincarnation of the genitals, and start over again!

Of course, the premise is that you are strong enough to be able to leave such a backup plan.

After studying the lack of chakra again, Uchiha Kiyoshi sighed helplessly, recorded the previous data, and stopped this research.

After recovering his spirits, Uchiha Kiyoshi got up and went to the clan's information room.

Along the way, Uchiha Kiyoshi kept thinking about his previous problems, and was also worried about gains and losses.

"Three months, can I find a way to use chakra to nourish my body? Alas! Did I go the wrong path?"

Uchiha Kiyo sometimes frowned and sometimes sighed. Fortunately, he walked with his head down, and there were few pedestrians, so no one saw him like this, otherwise he wouldn't have thought Uchiha Kiyo was crazy?

When he arrived at the information room, Uchiha Kiyoshi first greeted an old man at the door, and then walked in.

The reason why I say hello is not that I think they are characters like sweeping monks.

Instead, they are just such roles, but they don’t think it’s that simple.

The entire Uchiha clan, ninjas who have been here to check information, know that the old man at the door is not a simple guy.

Uchiha Yu, a retired ninja of the Uchiha clan, had the strength of an elite ninja at its peak, and now he is also the foreign elder of the entire Uchiha clan!

After all, not everyone can take care of the information room as an important place.

Uchiha Yu looked up and looked at Uchiha Kiyoshi.

He remembered that this junior came here to read books since he was a child and was a good child. However, some time ago, he also knew something from Uchiha Shin-shin and felt very sorry for Uchiha Kiyoshi's situation.

"You can only get out of this level in your heart. Alas! Such a junior who is eager to learn will not be bad, but it's a pity. If...

However, if this little guy really can come out, his future may be limitless!"

Looking at Uchiha Kiyo's back with his turbid eyes, Uchiha Ao made a secret comment in his heart.

Unfortunately, Uchiha Kiyoshi didn't know.

He didn't know that he was actually acupunctured by a person in a disguise. Sure enough, the ability of human brain to supplement is the strongest.

Uchiha Kiyo walked into the information room and walked straight towards the medical area.

The Uchiha clan is proud and conceited, but it is not careless, and the information is sorted out very neatly.

The entire information room is divided into different areas, the largest area is Sharingan-related information. Of course, only people from the Uchiha clan can enter here.

Then there is the basis of illusion, then there is fire escape, and then there are other escape techniques, medical treatment, sealing techniques and other areas.

Uchiha Kiyoshi has been reading books in the medical area recently, hoping to find inspiration for chakra to nourish the body from the perspective of improving physical fitness.

For four years, Uchiha Kiyoshi has often gone to and from medical areas to seal the art area, so Uchiha Yu is naturally very clear about it.

Uchiha Yu didn't say anything about this. In this regard, he would not interfere with the direction of his tribe's cultivation. Moreover, Uchiha Kiyoshi has "liked" to read this knowledge since he was a child, and it seemed that he could understand it. Maybe he really has talent in this regard!

It is naturally good to have an excellent medical ninja in the clan, or a ninja who is proficient in sealing techniques.

Moreover, with Uchiha Kiyoshi's situation, maybe it's good to be a medical ninja...

Uchiha Yu withdrew his gaze and closed his eyes and began to pay attention.

Time passed when Uchiha Kiyoshi was studying hard.

Uchiha Kiyo put down the "Ninja Body Forging Basics" and glanced across the bookshelf. Suddenly, a book called "Samurai Body Forging Method" attracted Uchiha Kiyo's attention.

"How could there be a samurai book here?"

When he picked up this book "Samurai Body Forging", Uchiha Kiyoshi was also confused. He didn't know what his family or a ninja family would collect this thing.

"Maybe it was obtained by accident, and then threw it away, it was a pity, so I put it here?"

Originally, Uchiha Kiyoshi planned to put this book back, but after thinking about it carefully, he had not studied how to improve the physical fitness of a samurai. Isn’t it a bit short-skinned to keep his attention on ninjas?

Should we study other systems?

With this idea, Uchiha Kiyoshi opened the book "Samurai Body Forging Method" and started to study it carefully.

Afterwards, Uchiha Kiyoshi specially found a few books on samurai and planned to study them by himself.

Two hours passed without realizing it.

Uchiha Kiyoshi seemed to be unaware of it, and was still looking at the information in his hand.

Now Uchiha Kiyoshi is holding a biography about a certain samurai.

Seeing that the samurai was 120 years old, Uchiha Kiyo's eyes narrowed, and he felt that his inspiration was coming.

One hundred and twenty years old is basically an impossible life span in the ninja world. Even Uchiha Madara was only hanged by the heretic golem, and he lived to be eighty or ninety years old!

After careful study, Uchiha Kiyoshi found that he was no different from other samurai and had never taken any magic pills. The only difference between this samurai who lived for 120 years was that he was relatively easy-going and rarely fought with others.

"So, there is no hidden wound on your body?"

Uchiha Kiyo murmured to himself. Looking at the book in his hand, his eyes were dissipated, and he didn't know where his thoughts had flown.

Uchiha Kiyo suddenly woke up and began to search for other samurai biography.

"Sure enough, it's not an isolated case. Any warrior who is not injured much when he is young or who is timely treated has a long lifespan.

The lifespan of humans in the ninja world, even if they do not practice chakra and do not have any disease troubles, they will definitely not reach a level of one hundred years!"

Uchiha Kiyoshi felt that his brain was hot and his breathing was rapid. He felt that he should have found his direction.

After five minutes of excitement, Uchiha Kiyo finally calmed down, took a deep breath, and slowly exhaled it. Uchiha Kiyo also controlled his emotions.

He picked up the previous "Samurai Body Forging Method" again, and Uchiha Kiyoshi started to study it. He felt that he must have missed something and needed to study it carefully again.

Before he knew it, it was already late at night. Uchiha Yu's urging, Uchiha Kiyoshi reacted, hurriedly apologized, put the book back to its original position, and left the information room.

When Uchiha Yu saw Uchiha Kiyo leave, he did not close the door immediately, and he set his sights on the information that Uchiha Kiyo had just studied.

"Samurai Body Forging Method"? What do you think of this kind of thing? Are you so dedicated to it?"

After taking out the "Samurai Body Forging Method", Uchiha Yu roughly read it for a while, he roughly understood the content, and asked in confusion, "Isn't it just a method of samurai body forging? As for being so serious? This set of samurai methods is a waste of energy. Although it is much better than ninjas in physical skills, it has been eliminated."

Uchiha Yu murmured to himself, suddenly, gasping for a cold breath.

"Hiss, this guy, won't it?"

Uchiha Yu couldn't believe it.

"So afraid of death? Even the samurai's body-tightening is so interesting? Medical ninjutsu, samurai's body-tightening... Hiss... the information is a bit big!"

Immediately, Uchiha Yu became worried about Uchiha Kiyoshi's situation.

This kid doesn't really have the will to learn the samurai, right? This is a pity. How could a child who works so hard be so frightened to death?

"Forget it, let's observe it again. If he really practices this, I will enlighten him at that time. Such a good seedling cannot be delayed on the samurai road."

Uchiha Kiyoshi didn't know that his behavior made the guardian think so much about it.

If I knew, Uchiha Kiyo would only say, "You think too much, and it's so difficult to exercise, and it's still slow to take effect, so I can't hold on!"
