"Very good. Now that you all know how to condense your own chakra, let's start with running."

Kakashi clapped his hands casually and said with a smile.

"But, Kakashi-sensei.

Since it is ninja training, we should practice ninjutsu or shuriken throwing, right?"

Little Sasuke immediately questioned. For such a simple physical training as running, you can just practice it in private.

Do you need to go to the training ground to train under the leadership of an ANBU captain?

This is different from what he imagined!

"Well, you are right.

But Sasuke, you should know the basic principle of condensing chakra, right?"

Faced with the student's question, Kakashi asked back easily without getting angry.

"Of course!"

When he heard that his theoretical knowledge was going to be tested, little Sasuke, who was still a little disappointed due to the attribute test, immediately held his head high and spoke proudly,

"The first step is to evenly mix the mental energy and physical energy in the body into [physical energy], which is also the basis for activating physical skills.

The second step is to convert [Physical Strength] into [Chakra].

In the third step, after the ninja extracts [Chakra], he can then use the seals to adjust it to perform different ninjutsu!"

After saying this, he quickly glanced at Naruto.

However, he found that the other person did not show any sign of enlightenment. He just nodded slightly, like a teacher who had just tested his students and received a satisfactory answer!

"Yes, so through a series of physical training such as running.

It can directly enhance our physical energy and hone our mental will in the process of fighting fatigue.

This in turn generates more physical strength to convert more chakra."

Kakashi explained patiently.

"So that’s it, I understand, Kakashi-sensei!"

When little Sasuke heard this, he suddenly realized.

No wonder his brother would tell him to do some basic physical training on weekdays.

He thought that he was doing this just to display the more gorgeous [Uchiha Style, Exercise, Shuriken Jutsu] and build up his physical fitness. As for the basics, little Sasuke was immediately eager to try it out when he thought that he could increase his chakra capacity through running.

"Since there are no problems, let's get started."

After saying that, Kakashi took the lead and ran forward, and little Sasuke and Naruto immediately followed.

"Sasuke, were you quite energetic when you were a child? You were quite cute~"

Naruto ran side by side with little Sasuke while chatting with the big Sasuke inside him with a smile.

"......"

Sasuke, who was sitting quietly in front of Kyuubi with his eyes closed, refused to discuss the topic and rolled his eyes when he heard this.

Since he woke up.

Whenever he saw Naruto and little Sasuke together, he felt extremely ashamed of little Sasuke's childish behavior.

It just so happened that Naruto got to mingle with his childhood self in advance.

Now they are Kakashi's students together and get along with each other day and night....

Hey~~

I'd better close my eyes and rest, out of sight, out of mind!

Sasuke felt helpless.

Naruto, who saw through Sasuke's inner thoughts at a glance, raised his eyebrows with a sly smile.

Ever since Sasuke silently shouldered the responsibility of secretly guarding Konoha, he has been wandering in foreign countries for a long time to collect intelligence.

He has become more and more mature, calm, careful and considerate.

Although it is much better than the increasingly cold and extreme state when he was an Avenger before!

But Naruto still misses his cold and arrogant appearance when Team 7 was just established.

Speaking of which, Naruto hasn't seen Sasuke's angry look for a long time!

Well, if I find an opportunity to show off a few skills in front of Sasuke next time, let him be convinced by his charm.

Even willing to be his younger brother, like Konohamaru back then, calling Naruto boss!

Sasuke's expression at that time must be very exciting!

Hehehehe๑乛◡乛๑...

Thinking of this, the corners of Naruto's mouth became more and more curved, and his eyes curved into crescent moons.

"What are you thinking about? Why are you smiling so obscenely?..."

Sasuke, who noticed that Naruto's expression was wrong, couldn't sit still.

He simply stood up and walked to Naruto.

This guy might be planning something wrong!

"Hey, hey, I want to know, I won’t tell you~"

Naruto shook his head proudly.

"( ﹁ ﹁ ) ~Cut~~

Idiot!"

Big Sasuke couldn't help but rolled his eyes.

He's such an adult, but he's still so childish!

Can you be more mature and steady like me?

Haha(￣ー￣), two childish ghosts...

Kyuubi, who was lying in the cage and dozing, closed his newly opened right eye again, feeling very speechless inside.

These two brats are really...

No eyes to see, no eyes to see at all!

Meanwhile, Naruto was running.

He habitually lowered his upper body and leaned forward actively.

Two pairs of young and white hands were raised back like bird wings.

The strides of his legs are not large, but the frequency of steps is very high.

Pushing the body forward at high speed through reaction force again and again is an extremely standard ninja run.

And this ninja-specific running posture was engraved into his bones.

It can also reduce air resistance like a soaring bird.

You can also lower your body to reduce the possibility of exposure when tracking enemies and avoiding pursuit.

At the same time, this running posture also makes it easier to take out the ninja tool and fight immediately when facing an emergency.

Truth is a required course for all ninjas.

Little Sasuke on the side also maintained the same running posture. It was obvious that he had received correct guidance at home.

But he is still young after all, even if he has done basic physical training before.

After running two kilometers, I started breathing heavily.

Sweat continued to seep from his forehead, and his underwear gradually became wet with it. He was obviously very tired.

【Even I am so tired, Brother Naruto may not be able to bear it anymore! 】

Thinking of this, little Sasuke, who always regarded himself as an older brother in his heart, quickly turned to look at Naruto next to him.

But I found that Naruto was breathing evenly at this time, looking calm, and not looking tired at all!

It’s like taking a stroll!

This, how is this possible?!

I realized that from beginning to end, I was the only one running in pain.

Kakashi-sensei and Naruto, on the other hand, were as relaxed as taking a walk!

Little Sasuke, who was already breathing through his mouth, subconsciously bit the tip of his tongue, his eyes becoming more determined.

The next second, he desperately increased his speed and rushed forward at an even faster pace!

He has a strong self-esteem, no matter how tired he is, he must beat Naruto once!

【Hmm? Have you compared them yet?】

【It seems that putting them together has a better effect than I imagined~]

Feeling the inexplicable fighting spirit behind him, Kakashi's heart moved.

He couldn't help but think of the days when Obito and he were silently competing in Minato's class.

Whenever this happens, Lin will always mediate it so that the smell of gunpowder between the two will not be too strong....

I really miss it!
