Naruto's strongest shock

Going retrograde all the way, it didn't take long for Naito Yu to find an excellent place to practice.

On one side is the woods, on the other side is a hilly area composed of mountains and rocks, and there is also a clear river flowing here.

"Okay! That's it."

Putting the dry rations aside, Naito Yu walked to a huge rock, stretched his muscles, and then punched out suddenly.

He didn't use force deliberately, but there was still a shocking force that suddenly shook with his punch.

hum! !

Cracks appeared in the air. Although Naito Yu's punch was aimed at the rock, it was actually still hitting the air.

boom! !

The mountain rock was hit by Naito Yu's punch, but because Naito Yu didn't intend to destroy it with all his strength, only a slight crack appeared.

"Fine, go on!"

Seeing this, Naito Yu nodded in satisfaction, retracted his left fist, and swung his right fist again.

The pair of fists alternated constantly, hitting the rocks, and there were constant rumbles.

Although Naito Yu's fist can use air as a stake, but air is not the object of force.

There is a force target, and there is no effect, which is a completely different effect.

Constantly punching the rock, Yu Naito's body was constantly trembling, first the skin, muscles, then blood and bones.

The whole body is continuously in this constant shock.

This was the first time Naito Yu continuously used the power of shock, when the whole body began to shake, the tingling feeling made Naito Yu feel as if he was floating in the sky.

This is the first time in the practice, to experience comfort!

"If I knew this earlier, I should have cultivated like this from the beginning."

Feeling the refreshing and hearty feeling in his whole body, Naito Yu complained in his heart, and then continued to practice more seriously.

Punch after punch.

The heart was beating powerfully, and the blood in the whole body surged continuously with the shock, flowing through the whole body.

The whole body's bones, flesh and blood are in shock.

This vibration further refines the flesh and bones.

The effect was even better than Naito Yu imagined!

Originally, after he opened the first door of Zhen and Bamen Dunjia, the power of the heart and the chakra of the first door feed back and promote each other, and then feed back to the blood flowing throughout the body. Even if he sleeps every day, his physique will continue to strengthen .

And if you continue to practice, it will be twice the result with half the effort!

In terms of physical skills, one month of his practice can be as good as other people's two months!

But now, Yu Ye didn't expect that not only the first door of the True Eight Gates of Dunjia would bring him an increase in his cultivation speed, but even the power of shock itself could assist in his cultivation!

Superimposed together, his physique is almost leaping forward.

Originally thought that three months would be enough to reach the standard for opening the second door of the Eight Doors Dunjia.

Now it seems that as long as it takes two months, it is more than enough.

However, Naito Yu did not get carried away with joy because of this, because the real eight doors are permanently opened in the reverse direction, so every time a door is opened, it takes a certain amount of time to get used to it.

And as more doors are opened, it will take longer to stabilize and a stronger physique to open the next door.

The further you go, the more difficult it is, which is no different from ordinary Bamen Dunjia.

"call!!"

It was another punch that finally shattered the rock, Naito Yu took a sharp breath and stepped back suddenly.

At this moment, his whole body was sore and numb, with a feeling of laziness coming from the bones and flesh of his whole body.

All of a sudden he lay on his back on the ground.

Sweat stained with mud, Naito Yu's clothes became dirty almost instantly.

But Naito Yu didn't bother to pay attention, but lay there with a face of comfort.

With the power of the shock, the whole body goes through a round, and what it brings is hearty and numbing comfort.

It is far more comfortable than doing push-ups before.

When the body gradually recovered and the numbness gradually disappeared, Naito Yu could almost clearly feel that his strength had directly increased by a bit!

It's almost an incredible thing.

Can directly feel the increase in strength, what kind of terrifying progress is this? !

"It should be because of training like this for the first time, all the impurities in the whole body were shaken out of the body, so it directly improved so much."

In addition to being overjoyed, Naito Yu also quickly found the reason.

Sure enough, when he continued to practice, the increase was not as terrifying as the first time.

However, it is still getting twice the result with half the effort!

The day passed quickly, Naito Yu dragged his tired body back home, this time he fell asleep right away.

Then the next day, Naito Yu continued to bring dry food and went to the back mountain to practice.

Although it is unsafe to practice here far away from the village, generally no one would come here.

Besides, it is said to be far away, but in fact it is not far from the village.

In the blink of an eye, more than a month passed, and Naito Yu's body showed some muscle lines visible to the naked eye.

The whole body looks thin and weak, but it is full of strength, which is almost unbelievable for a child who is less than nine years old.

Naito Yu's physique, in this more than a month's time, has improved so fast that it is shocking.

Especially in the first week, it was almost a leap-like growth, and then slowly entered a stagnation period.

boom! !

With a punch, the air buzzed and exploded, and the rock in front of Naito Yu was suddenly shaken with dense cracks, and then a hole burst out abruptly!

"Phew! Now, the power of my punch should completely surpass C-rank ninjutsu. Even the composite C-rank ninjutsu of two wind escape and fire escape is enough to smash it with one punch."

Satisfied with the damage caused by his punch with all his strength, Naito Yu nodded, but there was a trace of expectation in his eyes.

This power is slightly inferior to the B-level ninjutsu used by Uchiha Han that day.

However, as long as he opens the second door of the true eight-door dunjia and shatters B-level ninjutsu, he can definitely do it!

At this time, there is still one month left before the life-and-death duel between him and Uchiha Han.

During the period of his cultivation, the whole village was calm.

In other words, things about him were completely peaceful.

I don't know whether Hiruzen Sarutobi, Danzo, and Uchiha are restraining each other or what, no one came to interfere with him at all, as if he had been completely ignored.

But Naito Yu knew in his heart that this wasn't ignorance, but a struggle with each other, in a state of being silent.

Of course, this was only one of the reasons, and there was a second reason that everyone gradually ignored Naito Yu.

That is... the second Ninja World War has begun to show its ferocity!

The entire ninja world is already in a state of being full of wind and rain.
