Naruto, who was grinding and grinding, reluctantly formed a doppelganger seal, and sure enough, he still failed, even if he had a little bit to do with the Nine-Tails, he still couldn't control his chakra well.

Iruka looked at this soft doppelganger, how could he confuse the enemy if he couldn't stand up? It's obviously unqualified, no wonder Naruto hasn't wanted to use the doppelganger technique.

But Naruto's transformation technique was really good, and Iruka didn't even see any flaws, or didn't dare to look at it carefully.

"This doppelganger technique might as well use multiple shadow clones, it's useless."

Iruka tapped Naruto's head, and Naruto covered his head aggrievedly, is this Itachi pretending? Why do you like to point other people's heads so much?

"Any ninjutsu has its own reason, and it is impossible for a school to teach you ninjutsu that is useless."

Naruto pursed his lips and disagreed, waiting for the multiple shadow clones in the future, this doppelganger technique is really useless.

"It's just a little bit of use for the lower ninja."

Seeing Naruto's disdainful face, Iruka couldn't help but be annoyed in his heart, sacred ninjutsu cannot be violated!

"Today you have to learn! Otherwise.... emmm。 ”

Once again, Iruka experienced the pain of not being able to beat her own students, and she couldn't even educate them.

Iruka, who rubbed his cheeks, sighed, no wonder Miyome didn't look for anyone else, it was definitely because this Naruto was too skinny to control it!

"If you force me to study, I'll blow up the school!"

Iruka paused for a moment and looked at Naruto suspiciously, the ninja school is not small, does Naruto have so many detonation charms?

If there were so many detonation charms, how could Naruto still eat instant noodles! So after Iruka thought about it, he was sure that this Naruto would definitely not be able to blow up the school.

"You'll blow up Konoha! You'll have to practice your clone for me, too! Hokage-sama asked me to take care of you, and I had to make sure you had.... You will learn all the ninjutsu! ”

Originally, I wanted to say that Naruto would have a certain combat ability, but Iruka looked at the shuriken on the ground and wittily changed it to learn all ninjutsu.

Naruto pinched his chin, he didn't want to joke with Iruka, but now it seems that this Iruka is a bit of a man! Dare me to blast the ghost to make up the class, hum hum hum.

And Iruka looked at Naruto, who had become honest, and not only did a trace of pride flash in his heart, but he had finally conquered this great demon king.

The doppelganger technique will always be Naruto's shortcoming, and it is impossible to learn it in a day, Iruka scratched his head suspiciously, he had always thought that Naruto would not be able to learn it if he didn't work hard, but now it seems that this is not the case.

Iruka looked at the trees next to him, could it be because of Chakra's ability to control? If you don't control your chakra well, there will indeed be a situation where ninjutsu can't be released.

"I see, Naruto! Come and climb the tree! ”

Climb trees? Naruto looked at the tall trees beside him, and although he didn't know why Iruka wanted to let himself climb the tree, he reached out and climbed it.

That's right, it's climbing, not going up, Iruka patted his head, with Naruto's age, he definitely didn't know what climbing a tree was.

"Wait a minute, it's not like that."

Naruto looked at Iruka suspiciously, could it be that there was something wrong with climbing a tree? Isn't it just a matter of climbing up?

Naruto, who jumped down, looked at Iruka, who was about to demonstrate, only to see a faint chakra appear on the soles of Iruka's feet, and he slowly walked up with the trees attached.

Naruto also understood, where is this tree climbing! It's clear that it's just stepping on a tree.

"Well... It turns out that it's just stepping on it, and it should be called stepping on a tree. ”

Iruka jumped down, whatever it was called, as long as she could go up like this.

"You try it, remember to master the strength."

Naruto looked at the trees in front of him and stepped on them with a chakra, Naruto's chakra was not blue, but purple with the color of Honkai energy.

Click-

The trees that came into contact with Naruto Chakra instantly withered, as if they had been eroded by a virus, and the originally green leaves began to turn yellow, and then they fell.

Click-Gaba-Boom-

No sooner had Naruto started to exert himself than a good tree fell, shattering to pieces, as if the tree had been weathered for a hundred years.

Boom –

Iruka swallowed a mouthful of saliva, is this still chakra? How can there be such a strong erosion? Could it be that there really is something wrong with Naruto?

Naruto was also a little surprised, but then he remembered that the corrosive power of Honkai Energy was very strong, and after Naruto used the White Temper Armor, Chakra was also transformed into an energy between Honkai Energy and Chakra.

It does not erode the human body, but it contains the ability to corrode surrounding objects, and in terms of quality, it is much stronger than a simple chakra.

"Is this Chakra? Why is your chakra so corrosive? ”

Naruto's innocent little face was written all over I didn't know, and Iruka looked at it in a cold sweat.

"If you don't know, you don't know, do you need to write it on your face?"

Naruto's face was indeed full of I don't know, just written with a pen.

Iruka walked over to the broken tree and carefully picked up a piece of wood.

If it weren't for Iruka seeing the tree collapse with her own eyes, she would never have believed that the tree was still intact just now.

Although nothing was visible to the naked eye, it was clear that the piece of wood was as if it had been dead for a long time, and there was no life to speak of.

"Naruto, go back first, I have something to do."

The absent-minded Iruka picked up the wood and went straight to the Hokage's office, Naruto's face changed slightly, if the three generations knew....

Well, Naruto figured it out, if the three generations didn't peep, I Uzumaki Naruto bombed the school live!

In the Hokage's office, the three generations who were correcting the documents stretched out their waists, but they were only halfway stretched, when suddenly there was a loud bang at the door of the house, which startled the three generations.

Iruka kicked open the door to the Hokage's office, only to realize that it seemed to be the Hokage's office, not Naruto's home.

"Hokage-sama, I'm sorry, but I have something urgent to report to you about Naruto."

Iruka placed the wood on the Hokage's desk, and Miyome picked up the wood and looked at it with an unhappy face, as if there was nothing wrong with it, just a rotten piece of wood.

The third generation threw the wood back on the table, glared at Iruka and said, "Iruka! Are you here to entertain me? ”

Iruka paused for a moment, and quickly waved his hand, "No, Hokage-sama, this piece of wood was eroded by Naruto's chakra. ”

Chakra erosion? The three generations looked at Iruka suspiciously, the three generations had never heard of this situation, could Chakra still erode objects? If the chakra erosion ability is so strong, wouldn't the ninjutsu be even stronger?
