Of course, the teaching of the three-body technique is not as strict as the chakra extraction technique.

Because the three-body technique is also very simple, generally the chakra extraction can be extracted within ten days, and the three-body technique can basically be started within two days.

Therefore, when teaching chakra extraction, even if there is a student who does not succeed in extraction, half a day will be set aside every day to meditate and practice chakra extraction.

The difference between the three-body technique is that after three days of instruction, almost all of them are introduced, and once the students are introduced, Iruka no longer specializes in explaining the three-body technique.

Of course, as a teacher, Iruka will still do his best to test the three-body technique of the student from time to time.

The rest of the time is spent almost entirely on the teaching of cultural theory.

And among them, the one that occupies the most time in the cultural theory class is the will of fire, so Naruto who is patient enough is inevitably a little cautious.

Obviously, the three generations of Hokage Ape Flying Sun Slash, who had already comprehended it, would deeply embed the will of fire in the minds of the students of the ninja school when they were in their first year.

The will of fire has unconsciously changed the students' hearts about learning.

For example, in just one school year, there are many more people clamoring to become Hokage.

Even if they are civilians, the will of fire makes them firmly believe that as long as they work hard, they will definitely be able to become Hokage, and even some family members feel that they can become Hokage.

Therefore, these people who are clamoring to become Hokage have become the object of Iruka-sensei's headache.

In the hearts of these children, they think that if they can't become Hokage, it must be that they haven't worked hard enough.

So, in the minds of these children, it is undoubtedly a cool thing to become the Hokage and become an existence that protects the family.

And although Naruto was teaching the transformation technique, he succeeded in making a splash at a time.

However, apart from a few people such as Shikamaru, there are still few people who play with Naruto.

In addition, Naruto had already completed the extraction of chakra as early as when he entered the school.

So, basically, they all thought that Naruto had learned the transformation technique before he entered the school.

As for the doppelganger technique and the stand-in technique, Naruto did not show it in front of everyone, so he didn't bear to know that Naruto could also do the doppelganger technique and the stand-in technique.

The doppelganger and stand-in techniques are much more difficult than the transformation techniques, and in the minds of the other students, Naruto must not know these two techniques, because the difficulty of these two techniques is not ordinary.

Except for the twelve little powerhouses of Konoha, almost no one has learned it.

In addition, Naruto's cultural theory class exam results are crane tail, because Naruto is basically in accordance with the formula of three long and one short Xuan, three short and one long to choose the length of the mouth, and the length of the stab to choose C, it is strange that the test score can be high.

So, naturally, no one thinks that Naruto will be a genius, and naturally there are people who think that Naruto will be a philistine or something.

Naruto doesn't care about other people's eyes on him, in his previous life, Naruto was such a character, do his own thing, let others say go. Therefore, Naruto also lives a very comfortable life, and it is not an exaggeration to say that it is comfortable.

In fact, with Naruto's current chakra control, the amount of chakra is so huge that it can even be stuck in units, as well as the physical fitness that has become stronger and stronger because of the set, as well as the keen five senses.

There are also changes in the nature of the wind attribute chakra that have already been completed, and so on.

Naruto's strength can be said to have long exceeded the premise of the doppelganger technique and the stand-in technique, so these two techniques are naturally not a problem for Naruto.

Moreover, without the interference of the Nine-Tails Chakra.

Naruto had already learned these two techniques the moment Iruka-sensei performed them. Naruto's talent can be said to be incomparably demonic, even if he is a genius, it is impossible to learn these two kinds of numbers at a glance, but Naruto learned these two techniques at a glance.

"Yo, Nine Lamas, hello, I'm here again." Winter vacation, in the midst of the bitter cold wind and snow.

Naruto reappeared in the sewers of the sealed space.

"Hmph, little brat, what are you doing here with me again? I don't have anything to say to you! And I don't believe you either. Nine-Tails snorted coldly.

"Well, Nine Lamas, can you not call me a little brat? I'm seven years old! I've grown up, and it's a little helpless to be called a little kid by you. Naruto said with a grin.

"I don't care, I'm going to call you a little brat, how old are you? It's a big ghost. Nine-Tails said arrogantly.

"Alright, alright, call me whatever you want! Also, the reason why I came here is because I want to cultivate here, I want to cultivate the Spiral Pill here, because there are almost no people here to spy on me, so I feel that this is an excellent cultivation ground. Naruto smiled faintly.

"Hmph, this is not a place for you to cultivate, get out of here, stinky little ghost." The Nine-Tails said viciously.

"Hehe, Nine-Tails, even if you don't let me cultivate here, it's useless, this is not your territory, this is my consciousness space, you have to distinguish between priorities and priorities, Nine Lamas." Naruto spoke, looking inflated.

Yes, even if the Nine-Tails wanted to interfere with themselves with their own chakra, that would be something that the Nine-Tails couldn't do now. Because the amount of Chakra that the Nine-Tails can interfere with now is too little.

"Damn little ghost, wait for me to go out, and see how I clean you up." Nine-Tails said with a look of resentment.

However, Naruto ignored the Nine-Tails and concentrated on cultivating the Spiral Pill.

There are no water balloons, and there are no rubber balls here...... Relying entirely on one's control of Chakra to cultivate the Spiral Pill is ten times more difficult than having props from outside.

However, for Naruto, who is being monitored, the last thing he lacks now is time.

Therefore, although there are no props to assist him in cultivating the Spiral Pill, Naruto has time and can completely afford to consume it.

Moreover, although there are no props to cultivate the Spiral Pill, Naruto's control over the Chakra now is far greater than that of the Naruto who cultivated the Spiral Pill in the original book.

Plus, Naruto knew to cultivate with his hands from the beginning.

As well as Naruto's constant spiritual realm, plus, although there are no props in the sealing space, there are outside, as long as there is no movement, no one will pay attention to him.

Therefore, under Naruto's hard work, at the end of the winter vacation, Naruto had successfully mastered the Spiral Pill.
