Black Hawk's voice was exceptionally loud, and the violent vibration in the vocalization actually made Uchiha Yu feel the resonance effect of his chest and eardrum.

If you change to an ordinary ninja or ninja cat, I'm afraid that you will feel headaches and chest tightness.

No wonder Maoyou was reluctant to come out to see Black Hawk, and also prevented him from coming out with Miwa Masashi, it seems that this big cat has suffered a loss.

The Black Hawk didn't notice Uchiha's thoughtful expression, and it explained to itself, "The ancient monkey of Mt. Kongo dared to secretly contact you without me, and I could only come to you without caring about anything. ”

Only then did Uchiha Yu know the name of the white-bearded old ape, which corresponded to the name in the King Kong Mountain scroll.

He asked, "Black Hawk, you said that the ancient ape was hiding from you, but how did you know that it came to me?" ”

Black Eagle was half complaining, half proudly said: "It's not the first time that old monkey has done this kind of thing to hide from me, I have suffered many losses, so I sent my subordinate Ninja Eagle to stare at King Kong Mountain, and their every move is under my watch." ”

Uchiha Yu understood, this is the ninja eagle saw the old ape Ganggu leave Mount Kongo, and the black eagle who got the information tracked him all the way.

After learning about Gangu's purpose, Black Eagle temporarily decided to meet Yu Uchiha.

[I think I'll see you......]

Uchiha Yu looked into Black Hawk's eyes, convinced of the arrogance, purity, and clear stupidity revealed in his eyes, and nodded.

[It should be a visit, but Black Hawk's personality is too arrogant, and he doesn't know what politeness is, and he doesn't know any honorifics. 】

[It's too normal, the pride of the eagle hitting the sky, it's normal to have this kind of performance. 】

To be honest, Uchiha Yu's first impression of Black Eagle was good, far more than that of the white-bearded old ape.

Because of the clear stupidity in his eyes, Uchiha Yu misses the college students he once saw very much, the same pride and loneliness, and the same open-mouthedness.

But such a guy will be the best partner, a companion who can accompany you to fight bravely, and may even become your comrade.

Uchiha Yu nodded and asked, "I see, Black Hawk, are you trying to see me for something from me?" ”

Black Hawk nodded and said, "Yes, Yo Immortal. ”

"I want to establish a psychic contract on behalf of the Ninja Eagle Clan and the Uchiha Clan, and I also want your guidance to teach me to master the natural energy in my body."

When Uchiha Yu heard this request, he couldn't help but laugh.

If you accept the Ninja Eagle Clan again, the ninjas of the Uchiha Clan have four psychic beasts to choose from, I'm sorry for other Konoha ninjas, isn't their psychic beast resources too much?

Envy, jealousy, hatred!

Do you have?

Uchiha Yu felt that if he wasn't from the Uchiha clan, he would definitely have such emotions.

And Black Eagle actually opened his mouth to get his own guidance, which is too direct, the relationship between the two sides is not in place at all, how can he help it for no reason.

But before he could say no, the black eagle suddenly spread its wings, revealing its massive size.

I have to say that this scene is really shocking.

After the Black Hawk stood up straight, the height of a guy stabbed nearly 30 meters, and the wingspan reached an exaggerated 51 meters, which can definitely be called a cover.

It continued: "I have accumulated too much natural energy in my body, but I can't digest it at all, and I am growing in size. ”

"I love growing in size because it makes me stronger and better protected my people and the Wind Cliff."

"But since five years ago, I have found that my body size has reached its limit, and the continued growth of my body has caused me to become clumsy and lose strength."

"And I have a gut feeling that if I continue to grow, my life will be in danger, so I have to come and ask you for help."

"Please teach me to practice immortal arts, digest natural energy, and save my life."

The black eagle spread its wings like this, took a few steps back, and then turned downward, made a gesture of surrendering wings to the ground, and said sincerely: "Please save me, I am willing to pay my loyalty." ”

Looking at this huge black eagle that covered almost the entire clearing, the Uchiha was heartbroken.

The rejection that had come to his lips was swallowed back by him with a grunt.

He didn't expect that Black Eagle would directly offer his loyalty, how could he refuse?

Moreover, the ninja eagle clan of Chengfeng Cliff has considerable combat effectiveness, and it is even more exciting in terms of maneuvering and surveillance, for the Uchiha clan and for Konoha Village, it is impossible to refuse the contract of the ninja eagle clan.

As for the fact that the Uchiha clan may be envied and hated by ordinary Konoha ninjas because of the contract ninja eagle, Uchiha Yu decided to promote the integration plan in advance.

When the integration plan is successful, this sentiment will change from targeting the Uchiha clan to targeting a single ninja who has awakened the Sharingan.

In this way, although the problem still exists, it is an acceptable problem and easy to resolve.

Uchiha Yu nodded and spoke, "Okay, I've accepted your request, let me see how to solve your problem first." ”

The Black Hawk was overjoyed when he heard this, even if it was stupid and not good at saying good things, it was clumsy and thanked again and again.

And obediently lying on the ground, motionless let the Uchiha Yu jump on its body, and use natural energy to infiltrate the body for examination.

Uchiha Yu had only just begun to check, and he knew that Black Hawk's problem was serious.

The problem is too obvious, Black Hawk's body is full of natural energy, but there is no organization in the body, and even the meridians are completely blocked.

Because of the lack of natural energy flowing, Uchiha Yu couldn't find Black Hawk's meridians, let alone tell if the problem was due to the blockage of the meridians, or if some other problem was causing the blockage.

But he knew that life was in motion, and that any transcendent energy needed to flow.

Even his own Jin Dan is full of natural energy every moment, as vibrant as a living life.

On top of that, because there is no flow, almost all of the natural energy in the Black Eagle's huge body is accumulated in the torso, and the important wings and legs are in a dry state, completely supported by chakra.

As we all know, too much chakra can cause damage to the body.

The vast majority of chakra professionals like ninjas are short-lived guys, not only because of the battle, but also after the age of 50, there are not a few who die of serious illness.

Only ninjas like the three generations of Tsuchikage and the three generations of Hokage, who left the actual battle early because of their high power, can live to be 70 years old in good health.

And people like Uchiha Shinyin and Madara Uchiha are all because they have obsessions in their hearts, and they are dragging their bodies full of pain and suffering to hold on.

Madara Uchiha is supported by the energy of Hakujutsu and Nagato, and he can still maintain a sufficient quality of life, and even barely fight.

Before Uchiha Shin-Yin met Uchiha Yuu, he had been living in agony for a long time, unable to eat anything every day, hungry and in severe pain, tormenting him all the time.

Pain is the norm in the ninja's later years.

But whenever the willpower is a little weaker, the old ninja chooses to self-destruct instead of suffering bitterly, just like a terminal cancer patient.

The Black Eagle's wings and legs are related to its basic ability to survive, and as its body grows larger, so does the burden.

A body with a height of 30 meters and a wingspan of 50 meters cannot be supported simply by virtue of the quality of the body.

Not to mention flying and attacking, even if you stand up, your leg bones can be crushed by your weight.

Therefore, the wings and legs of the Black Eagle are constantly consuming a large amount of chakra for strengthening, that is, they are continuously using ninjutsu.

This burden is simply too great, and the decline in the strength of the Black Hawk can be said to be a matter of course.

That's all good, if it continues like this, the black eagle will inevitably break its wings and legs in unison within ten years, and death is inevitable.

According to Uchiha Yu's understanding of Chengfeng Cliff, when Black Hawk, a super powerful ninja eagle, dies, the ninja eagle clan will not be able to choose the next patriarch.

When the time comes, the rebellious ninja eagles will choose to go alone, and the so-called ninja eagle clan will disappear.

Uchiha Yu decided to treat this handsome big black eagle, and it was really unbearable to see it die.

But Black Hawk's physical problems were so severe that he didn't even know what to do.

He needs a healthy ninja eagle as a reference before he can start healing the black hawk.

So Uchiha Yu opened his mouth and asked, "Black Hawk, do you have any children?" Especially children who have already absorbed the energy of nature? ”

The shadow replied, "Yes." I have many children, but only one has absorbed the natural energy. ”

Uchiha Yu nodded, turned around and jumped off the Black Hawk's body, and ordered it, "Bring your child immediately, I need to know about the healthy Ninja Hawk's physical condition before I can decide on your treatment plan." ”

"Yes!"

Without the slightest hesitation, the black eagle jumped up with its legs, its wings vibrating, and the powerful wind escaped chakra, propelling its huge body to fly at high speed.

It turned into a black bolt of lightning and disappeared into the sky in the blink of an eye.

Uchiha Yu smiled in shock, and sighed: "This speed is really shocking, if it completely recovers its health, I don't know if it will be faster." ”

"If Black Eagle is a blessing in disguise and successfully enters the immortal path and enters the ranks of demon immortals, will it break through the limitations of time and space and achieve the ability to shuttle through space?"

"I'm starting to expect him to perform."

As Uchiha Yu's attention to Black Hawk increased, the name of Black Hawk in his mouth also changed from "it" to a more anthropomorphic "him".

It's like to Miwa Masayo.

The speed of the black hawk was extremely fast, and in less than half an hour, he flew back, carrying another large brown and black eagle on his back.

This large eagle is not small, and its wingspan has reached 12 meters, making it a giant eagle in every way.

It's just that compared to its father, it's very petite.

Uchiha Yu carefully examined the great eagle named Gray Shadow and determined the direction of the meridians in the ninja eagle's body and the operation of the chakra.

He even gathered some of the natural energy, and by observing the process of the gray shadow absorption, he determined the way in which the ninja eagle absorbed the natural energy.

Uchiha Yu was shocked, and he couldn't help but exclaim: "How is it possible that the ninja eagle is born with a defect in absorbing natural energy?" ”

"Life shouldn't be like this!"

"No, wait, I see, it's the chakra, the chakra, which is easier to use than natural energy, has changed the ninja eagle, which causes the ninja eagle to be in the process of mutation and adaptation, and there is a problem when facing the simultaneous existence of two energies."

Uchiha Yu quickly thought of the situation when the cat castle immortal art was popularized, including Mao Yu, all the ninja cats that had absorbed the natural energy fell, without exception.

And the stronger the immortal talent, the greater the damage received, and the most powerful Mao You even faced danger to his life because of this.

But how did the three holy places solve this problem?

Uchiha Yu suddenly clapped his hands and figured out what the problem was.

In terms of life level, slugs, toads and snakes belong to molluscs, amphibians and reptiles respectively, and the complexity of life is much lower than that of homeothermic animals, so it is naturally easier to adapt to changes in the new environment.

It happens to be the strongest slug with the simplest life form, the second strongest is the toad pill, and the relatively weakest is the white snake with the most complex life form.

Very much in line with Uchiha Yu's inference.

Moreover, they should not solve all the problems.

Whether it is the Wet Bone Forest, Miaomu Mountain, or Longdi Cave, the cultivation of immortal arts is very difficult, and even full of fatal risks.

There is only one slug in the Wet Bone Forest, and she doesn't need the inheritance of immortal arts, nor does she teach immortal arts to the outside world, so she doesn't care about it for the time being.

Miaomu Mountain and Longdi Cave are both huge families, and the descendants of Toadmaru and White Snake need to work hard to cultivate immortal arts and increase the strength of the clan.

Therefore, there are countless toad stone statues in Miaomu Mountain, and there are also headless bones in the Longdi Cave, no matter what they say, they cannot all be human corpses that have failed to cultivate immortal arts.

The vast majority of them must be the descendants of Toad Pill and White Snake, that is to say, they are through a large number of sacrifices, screening out the children of the survivors, which leads to more immortals, as well as huge snakes and toads.

Just think about it, how exaggerated the reproductive efficiency of toads is.

How could Toad Pill only have two children?

The children of Fukasaku and Shima can't only be the three Bunta brothers.

They are really just survivors among thousands of brothers and sisters.

Cold-blooded animals are still so difficult, and it is natural that homeothermic animals with more complex life forms are more difficult to adapt.

But there are five exceptions.

The Otsuki Hatsu and the Otsuki Hamura brothers are far more advanced beings than humans, and their life forms are bound to be more complex, but there is no difficulty in mastering the immortal arts.

This was completely contrary to Yuu Uchiha's inference, and he couldn't guess why.

The third exception was the Thousand Hands Pillar, where he was able to successfully master the Immortal Arts, relying on the correlation between the Wood Escape Blood Inheritance Limit and the Divine Tree.

The fourth is Uchiha Yu, and the fifth is Miwa Masayo.

How can he master immortal art without danger, of course he knows it clearly.

The key is that he splits the natural energy into five spirits, which correspond to the five chakras, and absorbs the natural energy that matches his physique.

Because all natural energy is self-adapting, it is not harmful.

From this point of view, the problem of ninja eagles is found, their physical attributes are too pure, and there is only wind escape chakra in their bodies, which is a thorough wind attribute.

In other words, the Ninja Eagle can only accept the natural energy of the wind spirit, and all other natural energy is harmful.

That's why Ninja Hawk's problem is so serious.

If you find a problem, you can find a way to solve it.

First of all, the unsuitable natural energy is extracted, and then according to the meridian structure of the gray shadow, the meridians of the Black Eagle are reconstructed, and finally the natural energy of the wind spirit is allowed to operate.

The first two steps are quite difficult, but the most troublesome is the last step.

Because he didn't know how Black Hawk's wind spirit natural energy operated in the meridians, the only example he could refer to was himself.

With Miwa Masashi as a precedent, Uchiha Yu believes that if he operates according to his own example, the probability of success is high, and he should be able to solve the problem.

But in doing so, he was revealing his true self to Black Hawk, a secret that only Miwa Masashi could know.

If this secret is leaked and is grasped by Miaomu Mountain, Longdi Cave, Wet Bone Forest, and Pure Land, it is very likely to cause a qualitative change in the power of the four Great Immortals.

At that point, the risk to Uchiha Yu will skyrocket.

You can't be cautious.

Uchiha Yu thought for a long time, and considering that Black Hawk had said that he was willing to surrender, he made up his mind.

He said to Black Hawk, "I've found your problem and thought of a solution. ”

"But I can't guarantee that my judgment is correct, or even your life."

"Black Hawk, do you still want treatment?"

Black Eagle didn't hesitate at all, and said directly: "I'm not afraid of death, I'm only afraid of getting weaker and weaker, please start treatment!" ”

But Uchiha Yu didn't start the treatment directly, but asked again: "Your treatment will let you know my secrets, can you keep these secrets?" ”

Black Eagle was stunned for a moment, but still said without hesitation: "Immortal You, I have promised you that if my physical problem is solved, I will offer my loyalty. ”

"Please trust in my loyalty."

Uchiha Yu looked at the huge eagle eye, and saw in it resoluteness, calmness, and clarity.

So he jumped on Black Hawk's head and said with a smile: "I believe you, then let's start now." ”

Then he commanded: "Stand up, spread your wings, and take to the skies!" ”

"The best place to heal your body is not on the ground, but in the sky, above the wind that never stops!"

"The ninja eagle should be on top, and the eagle strikes the sky!"

"There are only two results of this treatment, either the Black Eagle's body will be further healed, or he will die a heroic death in the sky!"

Uchiha Yu's words aroused the arrogance of the Black Hawk, and endless pride welled up in his heart, and he violently shook his wings and soared into the air.

With a fierce wind, the Black Hawk turned into a black bolt of lightning.

With his powerful wings, he didn't even make any hovering movements, and flew straight into the sky at an inclination of 75 degrees, flying out of a straight trajectory.

Just as he was flying, Yu Uchiha began his first steps, and a sea of chakras poured out of his body.

Fire escape, water escape, thunder escape and earth escape, the chakra of the four attributes is under the control of Uchiha Yuu, accurately surrounding the body surface of the black eagle, and constantly accumulating.

The Black Hawk flew higher and higher, through the clouds, and continued to rise at high speed, eventually entering the windy stratosphere.
