Uchiha Yu felt the cold wind for a moment, and was still not satisfied with the natural energy concentration of the wind spirit in it, so he ordered, "Go on!" ”

"Don't think about anything, fly higher!"

Wow——!

Black Hawk let out a high-pitched eagle chirp when he heard this, and he had already felt the changes in his body.

Under the influence of the chakra that surrounds the surface of the body, the natural energy of the dead silence like a stone moves, and even boils, and the black eagle has the illusion that its whole body is about to explode.

Now that it had an effect so quickly, his confidence in Uchiha Yu was even more sufficient.

Ignoring the soreness of his wings, and enduring the illusion that his body was swollen to the point of almost exploding, the black eagle flapped its wings with all its strength and continued to fly upward.

The black eagle flew higher and higher, the temperature became colder and lower, and the blue of the sky gradually turned into a deep blue.

When his panting became extremely thick, and his wings flapped with all his strength but he didn't feel enough power, Uchiha Yu was finally ready.

Complying with the attraction of the natural energy in the black shadow's body, he took the initiative to pour his chakra from the head into the black eagle's body.

Under the precise control of Uchiha Yu, the chakras of the four attributes are completely independent, yet intertwined, creating a powerful attraction with high-speed rotation.

With Uchiha Yu's control, even if Chakra entered Black Hawk's body, he still maintained enough control.

Natural energy has a strong tendency to bond with chakra, and the attraction of pure chakra is even stronger.

The fire spirit, earth spirit, thunder spirit, and water spirit in Black Hawk's body were stripped out and combined with Uchiha Yu's chakra to form the fairy chakra.

After the Immortal Chakra was synthesized, Black Eagle's body was affected, because it could not adapt and could not absorb, and there was an inorganic change.

The petrification of a toad, starting from the internal organs of the Black Hawk, made him feel great pain, as well as the instinctive fear of life.

The Black Eagle forcibly suppressed his fear, flared his wings desperately, flapped the thin air, and focused all his attention on "flying higher".

At this time, Uchiha Yuya had already done his best.

He controlled the synthesized Immortal Chakra, which flowed out of Black Hawk's body as fast as he could, regardless of the waste.

The Immortal Chakra was mixed with the natural energy in the Black Shadow's body, and these natural energies had accumulated in the Black Shadow's body for a long time, and had long been contaminated with his breath.

Therefore, Uchiha Yu's control over the Senjutsu Chakra is not strong enough, and the speed of the outflow is not fast enough, and the damage is unavoidable.

Fortunately, Black Hawk's body is large enough and his physique is also very strong, enough to kill the ninja's petrification effect, which is not fatal to Black Hawk.

Just like cancer can kill humans, but not whales.

The petrification caused by the Immortal Chakra is equivalent to a small stone growing in the body for the black shadow.

It hurts a little, but it's definitely not fatal.

A large amount of fairy chakra flowed out of the black eagle's tail like a jet, and because the concentration was too high, it actually showed a colorful color.

From a distance, the Black Eagle was like a rocket, spewing rainbow energy and flying high towards the inky blue sky.

As the Immortal Chakra continued to leak out, the natural energy in Black Eagle's body rapidly decreased, and at the same time, it was also purified, changing towards the pure natural energy of the wind spirit.

The burden was rapidly decreasing, and at the same time, the nourishing effect of the wind spirit's natural energy began to appear, and the feeling of the black eagle was getting better and better.

The soreness of his wings vanished, and his strength grew, and even as the air thinner and thinner, the speed of his flight began to increase.

When the sky took on the color of almost night, and the stars twinkled on it, the natural energy in the black eagle's body finally completed the final purification.

He chirped again excitedly, but the sound of the eagle was not loud because the air was so thin.

But Uchiha Yuu, who was standing on top of Black Hawk's head, heard it, and also felt the excitement and joy of Black Hawk, he stepped on Black Hawk's head, encouraged natural energy and said: "Now start the second step, pay attention to my operation, keep in mind the flow of natural energy, and the handling of body chakra, don't be mistaken at all." ”

Uchiha Yuu's natural energy of the wind spirit poured into Black Hawk's body, turning into a drill under his control, reshaping the meridians according to the meridian structure of Black Hawk's son Gray Shadow.

At this moment, Black Eagle felt soreness, numbness, pain, and itching, and at the same time lost control of his body, falling down in a flutter.

But he firmly remembered the reminder of Uchiha Yu, regardless of the discomfort of his body and the fear of falling, he concentrated on feeling the development and flow of the natural energy of the wind spirit in his body, and tried to remember all the details.

Just when the two of them were concentrating on Black Hawk's body and had no time to pay attention to the changes in the outside world, an accident happened.

The path of the Black Hawk's fall was exactly the path it had flown through, wrapped in the fairy chakra that flowed from his own body.

The violent friction between the feathers and the air does not produce high temperatures, but it accumulates a large amount of static electricity, which attracts the thunder chakra in the fairy chakra.

The gathering of the Immortal Chakra attracted the natural energy of the thunder spirit in the sky, and it also gathered on the feathers on the surface of the black eagle's body.

The dense appearance of short arcs rendered the black eagle like a large light bulb, and the outline of the body was not clear or not.

This is the more powerful and active fairy chakra releasing energy.

As the amount of fairy chakra increases, the tiny arcs of electricity soon turn into forked lightning and tree lightning, transforming into large-scale discharges.

There are more dense lightning sources in the sky, and the lightning bolts with complex shapes are clustered together, forming a spherical minefield with a diameter of more than 20 kilometers.

In the process of violent discharge, the Immortal Chakra is rapidly consumed, and constantly attracts the natural energy of Lei Ling in nature.

Thanks to the filtration of lightning, the surface of the Black Eagle's body gathered a layer of pure thunder spirit natural energy, and began to penetrate into its body along the meridian channels opened by Uchiha Yu.

The infiltration is subtle and silent, and neither Uchiha Yu nor Black Eagle is aware of it.

By the time Uchiha Yu found out, the wind spirit and the thunder spirit had been completely mixed together, and they had become a strange state that was distinct but inseparable.

The strange fusion of the natural energy of the two attributes made him unable to distinguish between them, and he could not get rid of them.

Uchiha Yu could only observe cautiously, and soon confirmed that the new natural energy was harmless to Black Hawk's body, and even the thunder spirit effectively stimulated the vitality of Black Hawk's body, making his self-healing speed significantly faster.

Uchiha Yu couldn't help but laugh, and said with emotion: "This is a blessing in disguise, after such a long ordeal, once you get out of trouble, you will usher in the wind and thunder gathering." ”

During the Black Hawk's fluttering fall, he only lost control of his body, but he did not lose consciousness.

Hearing Uchiha Yu's words, Black Hawk was naturally very happy and began to look forward to the strength of his body after recovery.

Uchiha Yu's meridian development work is not difficult, because Black Hawk originally had meridians in his body, but it was just clogged.

With his operation, it was easy to find the original meridian traces, and it only took a little force to re-penetrate, even if it was some nodes, it was not very difficult.

The real trouble is that the traces themselves are adhered in some places, and the places that should not be connected are connected, and the difficulty of rebuilding the barrier is much greater than penetration.

Uchiha Yu divided his mind into multiple parts, patiently dealt with different problems, and raced against time to penetrate the meridians of Black Hawk.

Until the meridians are connected into a circulatory circuit, and finally the acupuncture points at the end of the body are closed, the development of the meridians is completed.

Uchiha Yu reminded: "Black Hawk, the next is the final key, I will use my own power to drive the flow of your natural energy, but you have to take over gradually and control it yourself." ”

Black Eagle replied respectfully, "Yes, Yo Immortal, I will work hard!" ”

Uchiha Yu injected more of his own wind spirit natural energy into the black shadow's body, wrapped in the wind and thunder natural energy in his body, flowing along the meridians.

In the beginning, it was extremely difficult to push.

It's not very exhausting, but it's hard to control the natural energy of others, and it's often Uchiha Yuu's own wind spirit running in the air.

The Uchiha felt as if he was dragging a car covered in oil, his hands slipping wherever he grabbed them, and he couldn't use his strength.

Fortunately, the natural energy in Black Hawk's body belongs to the wind spirit and the thunder spirit, and his nature is very active, and the speed of his operation is gradually raised.

After the first Great Week, the basic cycle is established.

And Uchiha Yu's feeling has also changed, from dragging to pushing.

Although it still feels slippery, it is easier to exert force, and the running speed is significantly improved.

By the completion of the sixth Great Week, the Black Eagle's natural energy circulation speed had reached Uchiha Yu's expectations, and the absorption effect of the meridians had begun to appear.

The natural energy of the wind spirit and thunder spirit scattered all over the body was attracted to the meridians, further pushing the circulation speed to speed up.

But Uchiha Yu also found that his natural energy was swept into the core of the meridian circulation, and it could not be recovered.

After several attempts, he finally had no choice but to give up, allowing the natural energy that was deeply imprinted with his breath to remain in Black Hawk's body and run at the core of his meridians.

No matter what negative effects will occur in the future, it is better than breaking the meridian cycle that he has built up with great difficulty now, because if the current cycle collapses, Black Eagle will die.

The establishment of meridian circulation is of great significance to life.

This is a progress in the level of life, which is equivalent to a country's promotion from a small-scale peasant economy to a commodity economy.

In the era of the small-scale peasant economy, money was only an auxiliary, and no amount of change would lead to the collapse of the country, but in the era of the commodity economy, the amount of money was a fatal disaster.

With the exit of Uchiha Yu, Black Eagle took over his own meridians.

At the same time, he also regained control of his body, began to vibrate his wings vigorously, and began to fly again.

Black Eagle discovers that Yu's meridians are not only on his torso, but also on his wings and legs, and his strength increases greatly as natural energy flows.

He felt his body become lighter, his wings and claws more powerful, and the wings only vibrated lightly for a few times, and the momentum of the fall was completely eliminated.

Black Eagle also felt a powerful vitality emerge from his body, and the shadow of death that had plagued him for years had completely dissipated.

Wow——!

He let out a high-pitched eagle chirp excitedly, expressing his excitement and joy.

Boom——!

Black Hawk's voice was interrupted by an even more violent roar of thunder, and a thick bolt of lightning struck his head, as well as the Uchiha Yu in his head.

But Uchiha Yu is a thunder immune physique, and the lightning completely slipped over him, and finally hit the body of Black Hawk.

A huge amount of electricity flowed over his body, and the powerful Thunder Spirit natural energy squeezed into his meridians, powerfully changing the proportion of natural energy attributes in the meridians.

The inside and outside of his body were changed at the same time, and Black Hawk had no idea what was going on, and the whole eagle was stupid.

He instinctively spread his wings to stabilize his flying posture, and then attracted more violent thunder.

Uchiha Yu knows what's going on, it's Thunder Tribulation, and he's very experienced.

"Black Hawk! This is the thunder tribulation, it is the test of the world for your life level to jump, as long as you stick to the past, you will officially embark on the immortal path, and your strength and lifespan will be greatly increased. ”

Black Eagle asked, "Immortal, what if you can't hold on?" ”

Uchiha Yu replied bluntly: "If you can't get through it, of course you'll die." ”

Black Hawk was not frightened by hearing about death, but laughed heartily.

"Great, there is a risk of death, then the harvest will be great."

"I will definitely be able to persevere to the end, I will definitely become an immortal!"

Uchiha Yu was very satisfied with Black Hawk and said with a smile: "It's not to become an immortal, but to follow the immortal path I opened up and embark on a new path." ”

"Black Eagle, if you can hold on to the past, I will treat you as a fellow Daoist!"

"You will be my most trusted ...... Friend, I will share most of my secrets with you, in the great ninja world, second only to Miwa Masashi. ”

Black Eagle was overjoyed: "I am very honored to be a Taoist friend of the Immortals!" ”

His wings vibrated and he rushed straight towards the fierce lightning: "I will never let the Immortals down, I will definitely succeed!" ”

Black Hawk's massive body soared through the thunder and wind, his body glowing with lightning, and the violent lightning struck his body.

Under the wind and thunder, broken feathers and bright blood beads drifted all over the sky.

But the black eagle did not move at all, it was obviously an eagle with flapping wings and flying high, but its body stood majestically in the sky like a mountain.

Black Hawk's bravery and fearlessness greatly shocked Uchiha Yu.

In the face of danger and difficulties, he did not flinch and moved forward bravely, which made his soul be greatly tortured.

[Am I doing something wrong?] 】

[Yes, I was wrong!] 】

What did Uchiha Yu do wrong?

Of course, after killing three generations of Hokage, he has more power than the Thousand Hands Pillars, and despises the naïve ideals of the Thousand Hands Pillars, but he plans to shrink behind the scenes to control the ninja world, and not take the initiative to eliminate the war and other ninja villages.

He is not laughing at 50 steps and laughing at 100 steps, but laughing at 50 steps in 100 steps.

What difficulties, what the strength of Konoha Village is insufficient, all are excuses.

Now it is difficult to lead Konoha Village to unify the ninja world, can it be difficult to persuade Madara Uchiha to unify the country of fire with two families?

The Thousand Hands Pillar only knew that it was difficult, and he didn't know what kind of goal he could achieve, and he didn't know if he could succeed, so he still rushed forward fearlessly.

And Uchiha Yu had seen successful examples and knew the greatest benefits of unification, but he cowered and hid, thinking about handing over all the work to the four Hokage Orochimaru and the future Hokage.

It's nothing else, it's timidity!

He is afraid of the unknown information, high up, and full of six immortals!

Uchiha Yu raised his hand, but didn't give himself a slap in the face.

Because he has already made a decision and no longer needs to slap himself motivated.

It's not that I'm afraid of pain, and I'm not afraid of being embarrassed.

It's true!

……

The thunder tribulation is as fierce as in memory, and the target of the thunder tribulation is also the same tragic.

Black Eagle didn't know how many bolts of lightning and thunder he had endured, and his feathers all over his body were scattered, looking like a dehaired chicken, or scorched.

Even without the feathers, the chicken, ah, no, the eagle did not have the slightest idea of giving up and retreating.

He used the natural energy of the wind spirit as a feather, propelled his body to fly at high speed, and at the same time let out more and more high-pitched eagle chirps, chasing lightning and taking the initiative to meet the test of thunder.

The Black Eagle even opened its sharp hook-like beak to devour the scattered lightning and strong winds, frantically absorbing the natural energy of the Thunder Spirit and the natural energy of the Wind Spirit, and increasing the strength of its own meridian circulation.

He didn't take the severe pain and danger to heart, and not being able to admit defeat was his only thought.

How can you make the eagle soaring in the sky admit defeat?

Unconsciously, the natural energy released by the black eagle flapping its wings turned into the nature of wind and thunder, and the whirlwind was mixed with lightning, giving the black eagle more powerful power.

Surrounded by storms and lightning, a charred naked chicken fights in the sky in an even more violent catastrophe.

Uchiha Yu suddenly felt a movement under his feet, and when he looked down, he found that black and gold feathers were burrowing out.

Black Hawk's whole body, the charred skin is peeling off, and the exposed snow-white skin, the roots and feathers are growing rapidly.

Well, it looks even uglier.

But soon, the feathers grew and covered the Black Hawk's body again, and he became the handsome Black Eagle again.

But the black eagle is no longer enough to describe, these newborn feathers are no longer pure black, the root canal of the feathers is clearly golden, but the edges of the feathers are pale cyan.

When the natural energy flows, the black between gold and cyan emits a dazzling five colors.

A man wants clothes, a Buddha wants gold, and an eagle wants feathers.

The ancients did not deceive me, and this eagle became more beautiful and full of mystery.

Wow——!

The Black Eagle also sensed his new life, and let out a hopeful eagle chirp, high-pitched through the clouds, tearing through the clouds.

A golden ray of sunlight shone down and fell on the black eagle's body, making his whole body radiate with golden brilliance, like a golden eagle cast of gold.

The Black Shadow's Tribulation is over, and under the guidance of Uchiha Yuu, he embarks on the immortal path.

The Uchiha laughed heartily, "Congratulations on surviving the Tribulation, Black Eagle Michigo!" ”

Black Eagle responded excitedly, "Thank you for your guidance, Yosen! ”

Uchiha Yu shook his head and said: "Black Eagle Daoyou, in the future, you and I should call each other Daoyou, the immortal road is long, you and I encourage each other." ”
