Naruto, uncle, I am going to be Hokage!

"It's about to happen! Kakashi!"

In Konoha Village, from the top of a tall building, Metkai, who was filled with air waves and blue current, roared and rushed towards Kakashi on the opposite side!

Facing Kai who had undergone tremendous changes and whose strength had been transformed, Kakashi was under great pressure for a moment. He did not choose to take this move forcefully and kept retreating, trying to avoid Kai's attack.

Kai was faster than he expected!

Kakashi's face changed slightly.

Almost in the blink of an eye, it had covered a large distance and rushed in front of him!

Kakashi, whose scalp was numb, could only raise the short sword in his hand, use offense instead of defense, and slash at Gai's punch.

If you take Kai's attack forcefully, someone will die!

His strategy of replacing defense with offense really worked.

Faced with the terrifying cutting power of the polymer vibrating knife, even Kai, who was confident enough in his fists, did not dare to gamble at the cost of having his fists destroyed.

At the moment before the two were about to collide, Kai withdrew his fist, exerted force from his waist core, twisted his body, and blocked the direction of the attack to avoid collision with the blade.

Kakashi, who had dodged the attack, didn't have time to breathe when the sound of howling wind suddenly sounded in his ears.

Kai changed the direction of his attack, and with the help of the twisting power from his waist, he swept away with a roundhouse kick!

"Konoha Tornado!"

Damn it!

Feeling the cold wind whistling on his right cheek and the tingling sensation on his skin, Kakashi's pupils contracted for a moment.

At this distance, it's too late to escape!

At the moment when the attack was about to hit, he raised his right arm and resisted the attack with his unimportant arm, turning his body sideways to release the momentum.

Kakashi squatted on the ground, covering his right arm with his left hand, and his right hand was shaking slightly.

Kai stared across from him with an expression of shock and disbelief.

"Kai, I'm curious. Did you have a genetic mutation? Or did you undergo some kind of human modification to suddenly become so strong?"

Kakashi himself gained his current strength only after receiving a bionic eye transplant from Namikaze Mirai.

How long had it been since the last time Kai competed with him?

Kai, who could only struggle to hold on and suffered a miserable defeat last time, has grown tremendously in such a short period of time!

If he was told that Kai was also selected by Namikaze Mirai and underwent some kind of special human transformation, Kakashi would definitely not be suspicious.

"There is no such thing as transformation. If I insist on saying so, I think I have found my own direction!"

Kai looked emotional.

Without Namikaze Mirai, he might not be able to find the way he is now in his whole life.

The road to magnetic field martial arts!

This is a path that suits him perfectly and is almost tailor-made for him!

"So Kakashi! Let's fight! Use all your blood and youth and let's have a battle of wills!"

Kai's eyes seemed to be burning with blazing flames, and the electric current surrounding the air waves around him seemed to become more intense as his belief surged!

Unlike Kai's passionate passion, Kakashi's heart was filled with helplessness and annoyance.

Why do you want to meet this guy Kai?

He just wants to quietly savor the intimacy of heaven!

Although helpless, Kakashi knew that there was no possibility of avoiding the battle at this moment!

Facing Kai, who is full of fighting spirit, there are only two ways to win or lose.

On the top of the Hokage Building, Namikaze Mirai was witnessing everything that happened on that building.

In a duel between two different magnetic field systems, who will win?

Clang!

Kakashi was the first to attack.

After the previous brief confrontation, he knew well how fast and powerful Kai's attack was!

Once Kai takes the lead, what awaits him is a violent storm!

The left bionic eye runs extremely fast and calculates the best attack path. If you attack from this angle, the probability of success is 60%!

The polymer vibrating knife reflected the cold light, cut through a tricky arc, and stabbed hard into the lower part of Kai's right rib.

This cunning and insidious angle caused Kai to suddenly feel pressure. He used offense instead of defense, and punched Kakashi in the face.

Unwilling to lose both sides, the two finally staggered, switched positions, and faced each other again.

Pressing the button in the middle of the belt, the viscous nanofluid flowed out and covered his body. After a burst of illusion, Kakashi's body completely disappeared.

"Is this the trick again?"

Kai frowned.

The last time he competed with Kakashi, he was defeated by this move.

The invisible Kakashi appeared behind him at some point and placed the polymer vibrating knife across his neck.

Facing Kakashi who had no trace left, Kai suddenly became quiet, as calm as if he had changed into a bowl of water, and slowly closed his eyes.

A fierce battle suddenly became eerily quiet.

From a distance, it looked like Kai was standing quietly on the roof of the building, with no one else around him.

Sudden!

Kai opened his eyes and punched the back.

With a sound of physical impact, Kakashi's body was revealed. The short sword in his hand was making an attack posture. It was only a few centimeters away from Kai's body. His eyes were filled with a look of astonishment and disbelief.

Are you kidding me? !

His invisibility was seen?

"how did you do it?"

Kakashi was confused.

The optical invisibility ability of the nanobelt is not rubbish like the Iwa Ninja camouflage invisibility!

It truly disappears from the source, erasing all sound and optical reactions, and even chakra perception cannot be detected!

Kai, how on earth did you discover him? !

"vibration."

Kai grinned.

"Every time you move, the ground will produce weak vibrations. Through these vibrations, your position can be determined."

What the hell?

vibration? ? ?

Kakashi was stunned.

"Kai, are you really a human? Isn't it possible that your body is filled with monsters like spiders and bats?"

Can humans really feel vibrations?

Only Namikaze Mirai on the Hokage Building understands the principle of this scene.

Bionic superpower is the first stage of the magnetic field rotation system.

Kai's body has evolved, gaining the hearing of a bat and the vibration sensing of a spider.

Only then did Kakashi's optical invisibility be revealed in one fell swoop.

"Kai, you are more troublesome than I thought." Kakashi's expression became so solemn for the first time.

"Next, I will attack with all my strength. If you want to win, just take my strongest move!"

Waves of thunder arcs surrounded Kakashi's body, and together with the polymer vibrating knife in his hand, the blade was filled with blazing thunder arcs.

Different from the bioelectric current lingering in Kai's body, the current in Kakashi's body is a manifestation of extremely high attainments in Thunder Release, involving changes in the nature of Thunder Release.

"Are you finally serious? You feel the pressure! This is the passionate youth!"

Kai's fiery eyes were filled with intense excitement and trembling!

"Eight Gate Dunjia! Open!"

The air waves surrounding his body suddenly surged, thunder arcs surged in his hair, tic-tac-toe veins bulged on his forehead, and only the whites of his eyes remained, his gaze fierce.

The magnetic field martial arts superimposed on the eight gates of Dunjia are displayed on the stage of the ninja world for the first time!

The air between the two people, under the terrifying pressure of the two people, seemed to turn into two air walls, squeezing each other and breaking apart.

"Mysterious truth! Thunder flash!"

"Magnetic field martial arts! Chao Peacock!"

The strongest attacks belonging to different systems simultaneously displayed terrifying power at this moment.

Kakashi's body seemed to turn into thunder and lightning, and the short sword in his hand also turned into a piece of lightning!

Kai jumped into the sky, wielding his fists and throwing out countless afterimages, which rubbed against the air and formed a fire attack like a peacock spreading its tail.

This was originally the attack of the sixth gate of the Eight Gates Dunjia. It was integrated with the magnetic field martial arts to form his own unique magnetic field martial arts!

Thunder and fire! Technology and martial arts!

The duel between two different systems shows their strongest style at this moment!

The roof of the building was destroyed by the aftermath, and the power of the attack spread out. Many working villagers in Konoha raised their heads and looked at the top of the building with shocked eyes!

"Oh my God! What happened?"

"Are there enemies attacking the village?"

The top of the building had turned into a sea of ​​thunder and fire. The building began to collapse, the attack spread, and the nearby villagers fled in panic.

If the attack continues, the building may completely collapse, and the surrounding buildings hundreds of meters away will also be destroyed!

But Kakashi and Gai, who were at the center of the attack, were in unspeakable pain. Despite the full force of the attack, both of them could no longer hold back!

The outcome of this fight is beyond their control.

The current situation is already the result of their tacit control. Once there is a slight imbalance in the strength of the two sides, the terrifying energy accumulated in the confrontation will collapse like a dam bursting and burst out.

"Suffer it!"

Just when Kakashi was deeply regretting why he had to fight with Kai, the polymer vibrating knife in his hand suddenly heard a clear and crisp sound of shattering. The energy accumulated in this fight seemed to have found an outlet. Sweeping in at a speed!

Kakashi's expression suddenly changed.

Ruined!

The injuries to him and Kai were minor.

The surrounding villagers will be engulfed by the aftermath of the explosion.

The villagers below watched in horror as a raging energy erupted from the top of the building, and the entire ground began to shake.

Just when Kakashi was desperate.

Snap!

A clear snap of fingers suddenly came.

The raging and out-of-control energy strangely solidified. In the shocked expressions of Kakashi and Kai, the violent energy suddenly retreated and became as docile as a cat, shrinking into a small point and suspended between the two of them.

"Kakashi, I remember I said that pride and complacency are the greatest opponents of genius."

In Kakashi's dull eyes, Namikaze Mirai picked up the two people's full-strength attacks with his index finger and turned them into small dots. He gently twisted them, only to hear a crisp cracking sound, and they turned into dots of starlight and dissipated.

Kakashi was stunned.

Next to him, Metkai was also stunned.

A huge crisis, an out-of-control attack that focused almost all their strength, was resolved so easily.

They were so relaxed that they could hardly believe it.

If it weren't for the huge circular depression on the ground, they would even think that what just happened was just a dream.

"Of course you can become stronger quickly in a short time with the help of external objects, but you must also pay attention to the cultivation of your heart."

Namikaze Mirai said to Kakashi in a warning tone.

The latter's face turned pale and he looked at the broken polymer vibrating knife in his right hand.

In the previous duel, the energy accumulated exceeded the load-bearing limit of the polymer vibrating knife. This short knife, which he had always regarded as his most powerful weapon, had been completely destroyed.

"Don't forget, you still owe me something!"

Namikaze Mirai's sudden words made Kakashi's face freeze.

He suddenly remembered that the reason why he could be transformed by Namikaze in the future was because he agreed to something that must be completed as a condition.

Now he doesn't even know what that thing is!

If Namikaze asked him to do something weird or even degrading in the future, he would have to do it.

At this moment, no matter how regretful he was, he had to accept this reality.

Every gift from fate has a price secretly marked on it.

Kakashi knew this.

This was the price he had to pay for his power.

"The scientific research department has developed the latest polymer vibrating knife. I have already reserved it for you. That knife is much stronger than the one in your hand."

"I see."

After a complicated response, Kakashi deeply felt the unfathomable future of Namikaze.

Did he expect that his weapon would be damaged in this battle?

The laziness from before was completely gone in my heart, replaced by a strong sense of urgency.

Strictly speaking, he lost the battle just now.

Kai's strength is far beyond his imagination.

If he continues to mess up like this, he may be completely surpassed by Kai.

This is something Kakashi cannot accept!

Seeing Kakashi's appearance, Namikaze Mirai knew that his measures were effective.

After all, he is his brother Minato's disciple. With such a relationship, he naturally hopes that Kakashi can continue to become stronger.

That guy Minato was quite protective of his shortcomings. If he knew secretly, his students were addicted to Jiraiya's romance masterpieces all day long.

I'm afraid I will be quite upset because I didn't teach this student well in the first place!

Of the three in Minato's class, only Kakashi was left.

Namikaze Mirai was still very concerned about Minato's last remaining student.

After admonishing Kakashi, Namikaze Mirai turned his head and looked at Metkai beside him.

"Kai, you did a good job. You are far more talented than others in magnetic field martial arts!"

"Ahhh!!! Hokage-sama praised me, this is the passionate youth!!"

Kai fell to his knees, raised his head and hugged the sky, tears of excitement filling his eyes.

This exaggerated scene immediately caused Namikaze Mirai and Kakashi's lips to twitch.

It seems that after entering the magnetic field system, Kai's character has become more assertive.

Namikaze Mirai was about to speak when he suddenly seemed to notice something and turned to look at the sky in the distance.

This unusual scene immediately caught Kakashi's attention.

Also looking into the sky.

"That is……"

Kakashi frowned.

A bird? ? ?

To be precise, it should be a carrier pigeon, specially bred to send messages to other ninja villages.

With Kakashi's vision, he could tell the origin of this bird at a glance.

But the key point is that Konoha does not keep such homing pigeons in captivity.

In other words, this homing pigeon belongs to another ninja village.

Why fly here?

Just when he was confused, Namikaze Mirai raised his hand, and a terrifying suction force erupted, and the homing pigeon flying in the air was caught in his hand.

Sure enough, on the left leg of the homing pigeon, there was a mailbox tied to it.

After taking down the letter inside, Namikaze glanced at it and frowned slightly.

Kakashi, who was standing behind him, moved forward curiously, and after just one glance, his pupils suddenly shrank!

"This is!"

Sunagakure Village was attacked?

Is the opponent's target a tailed beast?

Request Konoha's aid? ? ?

A series of bombardments of information made Kakashi freeze in place instantly.
