I am Naruto, I sacrifice Asura at the beginning

The time span is one year.

For the time of the year, Naruto Uzumaki and Sasuke Uchiha soaked together almost every day.

After Sasuke Uchiha contributed the shadow clone technique he had learned from Uchiha Itachi, the two of them had the shadow clone deal with the ninja school a month later, while they themselves were in a high-intensity workout.

This year's time is very fulfilling for both Uchiha Itachi and Naruto Uzumaki, after all, every day is a boring and repetitive workout, and it is an individual who will feel unusually fulfilling.

"Brush!".

A figure walked quickly through the woods, and all that could be seen was a momentary shadow, and the sound was very slight.

The figure scurried through the woods, and in less than ten seconds it had made its way through the trees to the central lake.

The black figure suddenly stopped next to the lake, and the figure became clearly visible.

Black hair and black eyes, although the face still looks very immature, but it can be seen that this person is Uchiha Sasuke.

A year of training was an ordeal for Sasuke Uchiha.

God knows how he survived this year.

Because Naruto's guidance is a simple foundation, and it is still the foundation of the foundation, that is, it keeps repeating these foundations that he already understands.

But the most headache is that he has become dozens of times stronger than in the past because of these foundations.

Sasuke Uchiha, who once couldn't hold on, saw the change in himself, and once again threw himself into the basic workout painfully and happily.

In the process of exercising the basics, Sasuke Uchiha realized what Naruto meant by five years of non-stop training before, and that was really not a joke.

From the initial exercise of chakra control, then to control the production of chakra amount, re-proportioning physical energy and mental energy, in the exercise to sealing, the exercise of the three-body technique.

For a whole year, Sasuke Uchiha was exposed to only very ordinary foundations, but these foundations made him extremely strong.

The ratio of different proportions of chakra, only the right amount of chakra is manufactured, and the usual exercise saves the consumption of chakra at all times.

It is in this kind of exercise that Sasuke Uchiha can find that he has become extremely sensitive to chakra, and he is extremely meticulous to control every chakra in his body, so that he can achieve the lowest consumption and the highest effect.

It is a process from initial Xi to Xi.

After Xi getting used to it, Sasuke Uchiha was able to feel how much energy was saved by this practice, which could make his fighting time longer and keep him in the best shape longer.

It was because of this state that he had maintained for a year, and Sasuke Uchiha became more and more Xi accustomed to this kind of boring workout that he couldn't Xi at first.

After all, any workout is boring, and basic workouts may be the most boring, but this significant improvement allows people to put more momentum in workouts.

Sasuke Uchiha, who was standing on the edge of the lake, quietly looked at Naruto Uzumaki standing in the middle of the lake.

Of course, his focus was on the tiny crack that split the water at Naruto Uzumaki's feet.

"This guy actually did it. 」

There weren't too many undulations on the surface of the lake, but the crack really split the lake completely.

"The change in the nature of the Wind Attribute Chakra was actually done under the condition that those shadows were staring, and it was done under these circumstances. 」

Uchiha Sasuke knew a long time ago that Naruto Uzumaki was carrying out chakra nature changes, and even he himself was carrying out this nature change, but now he has only completed the first stage of chakra nature changes in the fire and thunder attributes.

It's not that it's so difficult to change the nature, but it's very difficult to avoid the attention of these shadows to complete the change in the nature of the chakra.

Also, it's about the dark part.

After Uchiha Sasuke had been training for chakras for nearly a year, which had made him extremely sensitive to chakra, he had noticed several chakra sources hidden in the woods as he often came here.

It's just that his perception hasn't reached that level yet, and he can't accurately perceive the specific location of the chakra, but he only knows that there are several chakra sources hidden in the woods.

That is, after perceiving the shadows, Uchiha Sasuke became more careful when he usually spoke.

It was because of this situation that Sasuke Uchiha looked at Naruto Uzumaki even more depressed.

"This guy, under the gaze of so many people, it's a shame that he can complete the nature change. 」

"If it were me, there would never be a way to complete the change of nature in less than a year with so many stares. 」

Although Uchiha Sasuke also has enough pride, if he can't do it in a short period of time, he can't do it.

Fortunately, his requirement for himself was to complete the change in the nature of the two chakra attributes of fire and thunder within five years.

After all, it was to be completed under the supervision of so many dark departments, and it was not possible to be discovered by those dark departments, and Uchiha Sasuke felt that he could complete the nature changes of the two chakra attributes on the basis of five years.

He looked at his hands.

"I'm really curious to know what level of my strength is, and I'm still four years away from graduating from the ninja school. 」

It's just that Uchiha Sasuke knows that he should be patient, and a year of self-cultivation has made him no longer feel angry like before, especially after being reminded by Naruto Uzumaki to be calm for a year, he Xi used to thinking calmly.

"However, according to our situation, it should not be very difficult to achieve special ninja after graduation. 」

It's not that Uchiha Sasuke is floating, but he has a certain amount of confidence and can feel that this is not a difficult thing to do.

The results of this year are the root of his thinking.

In a year's time, even if they just exercise their foundation, their strength has crossed to a height that their peers can't reach at all.

The shadow clone goes to take charge of the ninja school, and they take in those experiences.

The shadow clone itself is not the strength of the body, but the basic ability of the shadow clone can easily deal with the affairs of the ninja school, which is already very revealing.

Uchiha Sasuke knew that he and Naruto Uzumaki were not at all the heights that their peers could reach, and they had been exercising together all year long, and the tacit understanding between them was that they could already understand each other's meaning with their eyes even if they didn't speak.

Even if Uchiha Sasuke doesn't know what level of his strength is now, he already has some feelings.

Maybe the difference between the middle ninja in the ninja school and them is just the experience of fighting.
