The strongest technician of Muye

Early the next morning, Kakashi had just woken up and was sleepily going to the bathroom.

Suddenly, a watermelon head with thick eyebrows poked out the window.

Kakashi's left hand shook and he was taken aback.

"Yo, Kakashi, it's been a long time since a youth duel..." Kai

said halfway through the battle, and suddenly his face changed!

After three years, it appeared again, and the dragon raised its head!

Moreover, it seems to be even more exaggerated!

Seeing this, Kakashi generously walked outside the house and stood in front of Kai.

Kai struggled for a while, finally unfastened his white belt and pulled open the green tights.

The two put their heads together and studied them carefully.

Kakashi thought for a moment and patted Kai's shoulder with his left hand with a look of sympathy.

Kai burst into tears instantly.

"Come to the duel, Kakashi!"

Kakashi shook his head.

"I refuse."

Kai put the tights back on and carefully studied Kakashi's body.

"I heard that you just finished the mission, I came, it can't be somewhere hurt, right?"

When Kakashi heard this, his heart warmed.

No wonder he ran over early in the morning, it turned out to be worried about himself.

Kai scratched his head, looking a little confused.

"It doesn't seem to be a problem, let's have a fiery youthful duel, Kakashi!"

"Okay."

This time Kakashi did not refuse.

"So..."

Kakashi raised his right fist.

"Shout!"

Kai also raised his right fist with a look of excitement.

"The stones ... Scissors..."

"NO! Guessing is definitely not a good deal! Try that!

Kai pointed seriously at the distant Hokage Rock.

"I set the finish line over there to see who gets there first, got it?"

"It's really your style, Kai."

Kakashi was a little helpless.

"That's youthful enough, Kakashi." You will accept it, my eternal opponent!

"Well, just be happy."

"Woosy, it's about to start. I want to enjoy this game, hahaha.

Kai said, picking up a stone from the ground.

"Ready?"

"The engine is started and ready to go."

Kakashi made an ok gesture.

Sou!

As the stone ejected by Kai landed, the two instantly ejected and ran towards the distant Fire Shadow Rock.

"Oh roar

~" "Oh haha~"

Kai and Kakashi ran down the street, constantly speeding up, and the residential buildings on both sides were constantly left behind.

"Worthy of being my opponent, Kakashi! The wins and losses are only now officially beginning! "

Oh!"

Soon, the two arrived under the Hokage Rock and directly stepped on the vertical rock and sprinted up!

"Kakashi!"

"Kay!"

"Yay!"

In the end, Kakashi won Kai by a narrow margin.

"Whew... Whew..., how can you be repaired, you really deserve to be my opponent, and you have won again! Next, let's do 10,000 push-ups together! "

Kay."

"Huh?"

"I want to learn from you the Eight Gates of Dun Jia."

Kai looked sharply at Kakashi, staring into his serious eyes.

If it was someone else, he would never agree easily, but Kakashi...

"Shout, let's start now!"

"Well, Kai, let's go to breakfast first, today's training volume will not be small."

"Hahaha, yes, then we will leave now, and see who runs to the bun shop first!"

"Oh!"

......

After meals, the seventh training ground.

"Kakashi, I'll tell you the tricks of the Yamon Dun Jia now."

"Hmm."

Kakashi nodded and began to listen carefully.

Facing this man who had cultivated the strongest physical technique to the extreme and almost kicked out of the finale, he was also curious about how Kai usually practiced.

"Eight Gate Dun Jia - the full name is the Eight Gate Dun Jia Array."

"The chakra in the ninja's body flows in the meridian system, and the places that inhibit and control the chakra are eight doors: open, rest, life, injury, du, jing, shock, and death."

"Open the door gradually in order, and you will get the explosive growth of Chakra."

"If you open these eight doors at the same time, you will gain super extreme strength, and even let a subordinate have a power comparable to the shadow level for a short time, of course, the price is death!"

Speaking of this, Kai paused unconsciously, and he remembered his father's advice.

"Kakashi, learning this forbidden art requires self-restraint, especially the last gate, which can only be opened when you swear to death to protect the most important things!"

Kakashi heard Kai's serious words and was somewhat silent.

He knew that it was this ordinary sounding sentence, but it was the oath that Kai and his father had guarded with their lives.

"The first door of the Eight Gates Dun Jia is the opening door to lift the brain restriction, followed by the repair door that lifts the physical fatigue restriction, and the raw door and the injury door that increases speed and attack."

"When driving to the fifth door, it can reach the speed of sound, and the air flow brought by the movement can even destroy the ground!"

"After that, the qualities of the body will be further strengthened according to the opening of the door, until the opening of the door of death reaches the peak!"

"Of course, I can only open the first door at the moment, which is what I want to teach you today."

"By the way, what else did you not understand just now, you can ask me."

At this, Kai looked at Kakashi.

After all, when I first studied with my father, I let my father repeat it several times before I understood.

"Well, got it all, let's start training."

"Huh?"

Kai burst into tears when he heard this, is this a genius?

Well, worthy of being my lifelong opponent!

"Shout, then, training begins!"

"First, we do 10,000 push-ups."

Kakashi and Kai kept doing push-ups, so fast that they even turned into afterimages.

"And then five thousand raised legs."

"Shout, followed by 10,000 sit-ups!"

......

On the training ground, the evening sun shone on the two.

At this time, the two were already soaked in sweat.

Kakashi only felt that the suppressed emotions accumulated in his heart were beating violently with his heart, turning into streams of heat, which were continuously transported throughout his body through the blood, transforming into his strong fighting spirit!

"One last one left!"

"Shishi, the pre-training has been successfully completed, worthy of Kakashi!"

Kai jumped up, baring his white teeth and giving Kakashi a thumbs up.

Kakashi also stopped immediately, and sat on the ground with his hands behind his back, panting heavily.

The madness of the whole day, even if he has experienced a lot of experience, has long been overwhelmed.

"Kakashi, it's now, go beyond the limits of the flesh and use the chakra full of youth to hit the position of the door!"

Hearing this, Kakashi stood up strongly.

Close your eyes and feel it with your heart.

Five minutes later.

"First door, open door, open!"

A stream of air created around Kakashi's body.

"This, this, this..."

Kai was so shocked that he lost his speech!

Actually started success the first time, compared with his previous efforts, can only be said to be worthy of genius?

Looking at Kai's shocked look, the corners of Kakashi's mouth turned up slightly, and his eyes curved into a crescent.

He knew very well that the original body had not been able to go far in the cultivation of the Eight Gates of Dun Jia, so that until the finale, he could only open one.

Of course, this is also because the original body poured all his energy into the chakra eye and the chidori, and neglected the practice of physical arts.

However, now he already knows the terrifying future of strong enemies, whether it is Rokudō Madara or Otsuki Kaguya, if there is no immortal method and physical skill, ninjutsu alone cannot cause damage at all.

This is also the reason why he learned the Bamen Dun Jia.

Thinking of the future strong enemies who were one dimension higher than the current ninja realm, Kakashi sighed silently.

Then shook his head and said to Kai seriously: "Kai, I will keep the door open next, let's practice together."

"Ah, that's great, this is youth!"

Kai laughed.

"First door, open door, open! Take it, Konoha Rigid Cyclone! With

his hands over his head, he blocked Kakashi, who was spinning in the air, and used his strength to retreat to open the distance.

Then he moved at high speed around Kai, trying to use the dust raised to limit his vision and create a hand opportunity.

He didn't use a shadow avatar because it was a purely physical battle.

However, Kaide was unforgiving, an accelerated sprint intercepted in front of Kakashi, jabbed a combo to the opposite door, with the leg method, the attack was like a violent storm, accompanied by the sound of fists and feet breaking through the air, just fierce to the extreme!

Kakashi momentarily lost the lead and fell into a passive beating situation.

He quickly put his two arms up, covering his face and chest, left and right.

The arms of the two intersected, colliding hard, and each confrontation made a sound of flesh and bone colliding.

At this time, Kakashi found himself caught in Kai's rhythm, so he distanced himself again and tried to interrupt the other party's rhythm.

Seeing this, Kai increased his speed again and directly turned into a green afterimage!

I saw him stepping into the air, mixed with the sound of breaking the sky, moving directly at low altitude and high speed around Kakashi!

Seeing this, Kakashi's eyes flowed with a trace of solemnity, and his body chakra accelerated and surging, ready to meet the upcoming critical attack!

Suddenly, Kai, who had just moved to Kakashi's upper left in the air, appeared at the bottom right at the moment of disappearance, half-crouching and kicking diagonally towards his abdomen!

Kakashi didn't notice for a moment and was knocked away by a kick!

Kai burst from the ground and volleyed three times to kick the floating Kakashi higher.

At the same time, Kai also turned into a whirlwind and followed.

Bang!

"Konoha Rift!"

Kakashi, who suffered a heavy blow, smashed to the ground like a cannonball, and his body shot several times before he controlled his figure, and the pain all over his body made Kakashi's heart soar, so strong physical skills!

But that's what I want.

Kakashi steadied his heartbeat and rushed towards Kai again.

In this way, Kakashi fought until he could no longer keep the door open.

"Thank you, Kai. Let's get here today, continue another day, and let's go to the barbecue together. Kakashi

was a little touched by Kai's selfless teaching and sparring with herself.

He knew that if it were someone else, Kai would not be so unreserved, this is their only bond.

"Hahaha, Kakashi, there is no need to thank brothers, this is youth!"

"Woosy, let's compare and see who runs to the barbecue shop first!"

Kaiho laughed loudly, and slapped Kakashi's back hard with his right hand.

The emotion he had just accumulated instantly dissipated, and the corners of Kakashi's mouth twitched slightly.

It can only be said, is it worthy of Kai?

"Hi hi~"
