Konoha's Strongest Technician

Early the next morning, Kakashi had just gotten up and was going to the toilet drowsily.

Suddenly, a watermelon head with thick eyebrows and big eyes poked out of the window.

Kakashi shook his left hand and was surprised.

"Hey, Kakashi, let's have a youthful showdown after a long time..."

Halfway through Kai's high-spirited words, his expression suddenly changed!

Three years later, it appears again, the dragon raises its head!

Moreover, it seems to be even more exaggerated!

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

Kai struggled for a while, then finally took off the white belt and unzipped the green tights.

The two put their heads together and studied it carefully.

Kakashi thought for a moment and patted Gai's shoulder with his left hand, a look of sympathy on his face.

Kai burst into tears instantly.

"Let's duel, Kakashi!"

Kakashi shook his head.

"I reject."

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

"I heard that I came just after you completed the mission. Could it be that you were injured somewhere?"

Kakashi felt warm in his heart when he heard this.

No wonder he came here early in the morning, it turned out to be because he was worried about himself.

Kai scratched his head, looking confused.

"There seems to be no problem. Let's have a youth-burning duel, Kakashi!"

"Ok."

Kakashi didn't refuse this time.

"So......"

Kakashi raised his right fist.

"吆西!"

Kai raised his right fist with the same excitement.

"Rock...scissors..."

"NO! Guessing will never work! Try that!"

Kai pointed to the Hokage Rock in the distance with a serious look on his face.

"I set a finish line up there and let's see who gets there first, got it?"

"It's really your style, Kai."

Kakashi was a little helpless.

"This is youthful and passionate, Kakashi. You will accept it, my eternal rival!"

"Okay, as long as you're happy."

"Xinxi, it's about to begin. I want to enjoy this game, hahaha."

Kai said, picking up a stone from the ground.

"Are you ready?"

"The engine is started and ready to go."

Kakashi made an OK gesture.

Whoosh!

As the stone thrown out by Kai fell to the ground, the two of them jumped out instantly and ran towards the Hokage Rock in the distance.

"Oh ho~"

"Oh haha~"

Kai and Kakashi ran down the street, constantly increasing their speed, and the residential buildings on both sides were constantly being left behind.

"You are worthy of being my opponent, Kakashi! The victory begins now!"

"Oh!"

Soon, the two of them arrived at the foot of the Hokage Rock and sprinted up the vertical rock!

"Kakashi!"

"Kai!"

"Ah ah!"

In the end, Kakashi defeated Gai by a narrow margin.

"Huh...huh...how can you repair it? You are indeed my opponent. You won again! Next, let's do 10,000 push-ups together!"

"Kay."

"Ok?"

"I want to learn Eight Gate Dunjia from you."

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

If it were anyone else, he would never agree easily, but Kakashi...

"Xinxi, let's start now!"

"Well, Kai, let's go have breakfast first. Today's training volume will not be light."

"Hahaha, that's right. Let's leave now and let's see who gets to the bun shop first!"

"Oh!"

......

After dinner, the seventh training ground.

"Kakashi, I'm going to tell you the secret of Eight Door Dungeon now."

"Ah."

Kakashi nodded and began to listen carefully.

Facing this man who had practiced the strongest physical skills to the extreme and almost kicked him to the end, he was also curious about how Kai usually practiced.

"Eight Gate Dunjia - the full name is the Eight Gate Dunjia Formation."

"The chakra in the ninja body flows in the meridian system. The places where chakra is inhibited and controlled include the eight gates of opening, rest, life, injury, Du, Jing, Jing, and death."

"Open the doors gradually in order, and you will get an explosive increase in chakra."

"If you open these eight gates at the same time, you will gain super extreme strength, and even allow a genin to briefly possess Kage-level power. Of course, the price is death!"

At this point, Kai paused unconsciously, remembering his father's advice.

"Kakashi, learning this forbidden technique requires self-discipline, especially the last one. It can only be opened when you are determined to protect the most important thing to the death!"

Kakashi was a little silent when he heard Kai's serious words.

He knew that this simple-sounding sentence was an oath that Kai and his father guarded with their lives.

"The first gate of the Eight Gates of Dunjia is the door that lifts the limitations of the brain, followed by the gate of repair that lifts the limitations of physical fatigue, and the gate of life and injury that increase speed and attack."

"When it reaches the fifth gate, it can reach the speed of sound, and the airflow brought by it can even destroy the ground!"

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

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

"By the way, if you don't understand what I just said, you can ask me."

At this point, Gai looked at Kakashi.

After all, when I first learned from my father, I had to ask my father to repeat it several times before I understood it.

"Well, I understand everything, let's start training."

"what?"

Kai burst into tears when he heard this. Is this a genius?

Well, he is indeed my lifelong rival!

"Xinxi, then, training begins!"

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

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

“Then five thousand leg raises.”

"Xinxi, then ten thousand sit-ups!"

......

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

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

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

"One last moment left!"

"Xinxi, the pre-training is successfully completed, you are worthy of Kakashi!"

Kai jumped up, showed his white teeth, and gave Kakashi a thumbs up.

Kakashi also stopped immediately, sitting on the ground with his hands behind his back, breathing heavily.
