The ninja's pursuit of combat ninjutsu is indeed far beyond medical skills......

The ninjutsu of the five elements attribute has the most direct destructive performance, although it is possible to gain great power by learning medical knowledge and practicing medical ninjutsu, but compared to the simple and direct five elements ninjutsu, there are really few people who care about medical ninjutsu involving yang escape and biomedicine. Pen ~ fun ~ pavilion www.biquge.info

Therefore, compared to other libraries that are uninhabited, there are still many people in the ninjutsu library that records countless ninjutsu materials.

As soon as Yuehua Ai entered the ninjutsu library, she found that this place was different from the previous medical information room, the room in front of her was on the sunny side of the library building, the lighting was suitable, the area of the site was not only five or six times larger than the former, but also the bookshelves were neat and numerous, the entries were clear, and there were many more tables and chairs by the windowsill.

After a cursory look, Yue Huaai found that this place is also divided into three data areas: ninjutsu, illusion, and physical arts, just like the distinction of ninjutsu. The size of the three data areas is different, but the illusion area and the body area together are not as large as the area of the ninjutsu area.

Although Yue Huaai has always had a great interest in illusion, he didn't know about it when the illusion information appeared in front of him.

Walking into the ninjutsu information area, Yue Huaai carefully searched through the rows of bookshelves, compared to the long-awaited illusion, he was now more urgent about the information about the change in the nature of Chakra.

Yuehuaai's own strength is mainly composed of ninjutsu combined with physical arts, and his perceptual talent is now mainly used to assist in reconnaissance, although it can also play a role in predicting some prophetic premonitions when fighting, but it is still a lot worse than the 100% accurate counterattack of the stress response state.

At this stage, Yuehua Ai's strongest combat power composition is still ninjutsu, but when he perfected the aura jade and simplified the aura bullet, he has not made any progress in ninjutsu for such a long time from then to now.

Yue Hua Ai knows far more about his own situation than others, and in the years he has been cultivating with Jiraiya, through learning ninjutsu and transforming ninjutsu, the potential he has accumulated has actually been almost completely transformed into strength. If the accumulation and potential are insufficient, of course, there will not be much progress.

After accumulation, the growth of Yuehua Love has finally ushered in a bottleneck.

These days, although he has not relaxed in the refining of chakra, but unfortunately limited by his physique and age, his progress in chakra has been extremely small.

The growth potential of chakra is too demanding for physique, and the total amount of chakra for a ninja has to account for eighty percent of the physical and spiritual requirements, and only the remaining two percent is the diligence of the ninja's cultivation.

Therefore, no matter how much time a ninja spends refining chakra, the growth rate of his chakra will never be comparable to the increase brought by the growth of his physique. Because the chakra in the Hokage world needs to be synthesized by the human body, it needs to be based on the strength of the human body.

For example, the human physique is like a mineral deposit, and the chakra is like the resources contained in the mineral deposit, so the cultivation of the ninja is the development of the mineral deposit.

Therefore, even if those small ore veins are highly developed, they are basically not as good as the slight mining of those large mineral deposits.

Think about Naruto, when he was a teenager, he had already reached four times the amount of chakra in Kakashi, and that wasn't counting the nine-tailed chakra in his body, otherwise the difference between the two would be a hundred times.

The refinement of Chakra is not the cultivation of immortals in the Xianxia world, and if you want to make Chakra grow infinitely through the continuous refining of Chakra, it is simply a joke!

The length of time for refining the chakra does not represent too much, think about why the three generations of Hokage died at the hands of Orochimaru in the future, the main thing is not because of his aging or declining physical strength, the root cause is nothing else, the chakra is not enough during the battle.

The chakra that has been refined for decades by the three generations has not performed brilliantly in battle, so it can be seen that refining chakra does not have a too obvious effect on increasing the upper limit of chakra, and the greatest use of refining cultivation is to increase the recovery speed of chakra!

The slow growth of Chakra is Yuehuaai's biggest shortcoming, but he is really helpless about this, after all, this is not something that can be changed by hard work alone.

In terms of ninjutsu cultivation, he has almost reached the limit of what he can achieve. When the super A-level ninjutsu of Lingguang Jade was developed, it meant that his cultivation in the change of chakra form had exceeded the limit.

If he wanted to continue to strengthen his ninjutsu strength on top of the existing chakra, the only feasible path he had left was to cultivate the change in the nature of the chakra.

Think about the Wind Escape Spiral Shuriken created by Naruto in the original book after mastering the change in the nature of the Wind Attribute Chakra, how many levels of Naruto's combat power has been increased by that ninjutsu alone!?

Therefore, in Yuehua Ai's expectations, whether he mastered the change of the water attribute chakra, or the chakra change of the wind attribute like Naruto, as long as he mastered the change of any nature and integrated it into the aura jade, his strength would definitely usher in an unprecedented explosive growth!

It's a pity that the ideal is very plump, but the reality is relatively skinny.

On the way to Konoha with Jiraiya, Yuehua Ai once asked him for advice, but unfortunately Jiraiya is only proficient in fire and earth in the Five Elements Ninjutsu, and he is well aware of the nature changes of fire and earth chakra, but when it comes to the attribute changes of wind and water, in addition to knowing some of the basic manifestations of the two, he also doesn't know anything about the deeper aspects.

Although he was a little disappointed, Yuehua Ai still consulted about the changes in fire and earth attributes in line with the idea of touching the class, although he had no way to cultivate, but it was always good to know more, after all, who knew if he would meet a ninja who was proficient in the changes of fire and earth attributes in the future.

Recording some of his incisive explanations, when thinking about the changes in the attributes of fire and earth, he also summarized the characteristics of the changes in these two attributes, and made some conjectures about the other three attributes with his own unique cognition.

Although he already had a reasonable conjecture in his heart, he was still looking forward to the most orthodox statement in the ninja cultivation system.

And today, through this library, which records almost all the theoretical foundations of ninjutsu, he finally has a chance to get a glimpse!

Looking for the past little by little on a row of tall bookshelves, after a lot of time, Yuehuaai finally found what she thought of on a bookshelf.

"Chakra's Changing Nature Basis"!

The title of the book is so simple and straightforward!

Yuehuaai was a little excited to take out this slightly shabby book, as if it had been read by countless people.

Although he hadn't opened it yet, just a little bit of it, Yuehua Ai had a discovery that made him excited.

There is a small signature in an inconspicuous place on the back of the book, and that name is a thousand hands!

Senju Kazuma is the second Hokage of Konoha, the younger brother of the original Hokage and one of the founders of Konoha Village, who made an unparalleled contribution to the prosperity of the village while he was alive.

Senju Kazuma is best at researching and developing ninjutsu, he is the most creative ninja of his time, he not only developed countless conventional combat ninjutsu, but also left a lot of forbidden jutsu.

Like the Flying Thunder God technique that Bo Feng Shui Gate relied on to become famous, the reincarnation of the filthy earth that caused countless waves in later generations, and the shadow clone technique that Naruto is best at, are all masterpieces left behind by him.

There is no doubt that in the study of ninjutsu, Kama has reached an unprecedented height, and the books he left behind, even if they are not forbidden or ninjutsu, even if they are just about some basic ninja cultivation issues, I am afraid that people will flock to it, after all, his name is a thousand hands, even if it is a basic question, his insights will be far beyond the cognition of ordinary ninjas.

I couldn't wait to sit down on the chair by the window, carefully put the book on the table and uncover the cover, and read it word for word, and soon Yuehua Ai was addicted to it.

Sure enough, after all, the ninja world is an existence with a thousand-year-old history, even if you are a traverser, you must be in awe of this place. It's just a simple book, which makes Yuehua love a lot of pride in her own traversal.

This book not only has a detailed introduction to the ninja system, but also has endless whimsical ideas in the cultivation of ninjutsu, and there are many thought-provoking places, and between the lines, he knows that the other party's knowledge of chakra is not behind him at all.

The interweaving of two cultures, the collision of different civilizations, just a short time of reading, made Yuehua Ai feel that his originally somewhat exhausted inspiration surged again, and countless ideas and ideas were brewing in his mind.

"Squeak-"

Just when Yuehua was immersed in the world of books, a sharp friction sound suddenly woke him up, and when he looked up, he found that the young man who had been sitting in front of him and shared a table with him was getting up, and the sound before was caused by him pulling the chair.
