Inside the indigo dyeing class.

"I'm really sorry!"

“……”

Looking at the uncle who was lying on the ground with his hands folded and apologizing exaggeratedly in front of him, the corners of Kakashi's forehead twitched, feeling that he was indeed too young.

Maybe it's because Kakashi meets all the adults who are very reliable and calm and elegant, but in fact, Kakashi has a vague sense of respect for adults that he can't explain.

It's always been a polite, honest and reliable Aizen Sosuke, or the cat-faced masked uncle who wears the same style of Haori and follows him to pull out the weeds in the tomb, or the shadows and staff who also occasionally appear in the Aizen garden and look serious.

No matter which one it is, it seems to be a full of talent. Even when Kakashi was passing through the village, those who imitated Aizen and walked around the village wearing Haori would take the initiative to help the others. Whether it's helping to sell goods or some small tasks, you can ask them to do it.

After months of exposure to such an environment, Kakashi actually developed an unconscious fantasy about adults.

In his ideals, adults should probably be like that.

Be polite, calm and indifferent, and not rush in the face of big things, this is what an adult should be.

Then he was completely disgusted by the toad-like lying on the ground in front of him, one of the three ninjas with his hands folded.

How can there be such a shameless adult in the world?

First questioned your own development ability, then insulted your safety as a researcher, and now you come and put on such a scoundrel and beg for forgiveness, won't you speak well as an adult?

And according to Kakashi's recollection, Jiraiya, one of the so-called three ninjas, doesn't seem to be a good thing. Peeping into the women's bathhouse,Often sexually harassing others.,If it weren't for the powerful and capable three ninjas among the ninjas.,It's estimated that he would have been caught and re-educated at the education department.。

Even now, when he confesses his mistake and apologizes, that attitude and behavior makes Kakashi's forehead bruise. As the leader of the three ninjas, the Konoha ninjas, and the veteran ninja who has experienced many years of war, and the disciple of the three generations, this older ninja with white hair who looks quite similar to him lies on the ground and shouts:

"Just forgive me this time! Little brother Kakashi! And at the end of the day, I'm just kind, I didn't expect you to be so good at researching. ”

“……”

Kakashi's forehead twitched again.

"Ah, how about we study the Immortal Mode with each other? Your bloody pretense is too ugly, and this is the secret method of Miaomu Mountain, right? It's much better than your stuffy research, do you want to learn? ”

“……”

Kakashi's forehead was covered with blue tendons, and there was a faint tendency to redden.

"That's right! I really can't do it, I still have some good things here, but I wrote them on the battlefield and haven't sent them to the publishing house yet, do you want to take a look at them first? ”

“…… Call. ”

Looking at the clear sky, Kakashi Hachiki closed his eyes and exhaled deeply.

Then he turned his head to look at Jiraiya, one of the three ninja who had stood up and grinned loudly.

After Aizen's education, Kakashi has a preliminary understanding of what scientific analysis is and what it means not to be angry in the face of illiterate and arrogant people.

So he was just calm, objective, and expressionless, looking at the hip-hop pretending to be stupid Jiraiya.

"First of all, the blood-moving suit is not the so-called immature technology as you imagined, we have long studied your immortal mode of blending with special techniques, and the answer is that there is no universality."

“？”

"The immortal mode of Myoki Mountain probably requires the use of special materials, long-term training, and then through its own adaptability to constantly adjust the ratio of natural energy and chakra, and form an instinctive long-term mode after active operation, right? If you're not mistaken, you may need someone else to help you if you don't know how to use it. ”

“？？”

"So we don't need this old and outdated technology for the development of the blood suit. He is too independent and has no universality. The reason why the immortal mode has not been popularized is because he has too strict requirements for physique, talent, and understanding. There are reasons for the manipulation of one's own chakra, the discernment of natural energy, and the fear of petrification. ”

“？？？”

"It's not that we can't do it, it's just because it's not universal and unsafe, that's why we choose today's blood suits. Understand what universality is, uncle. ”

"Big, uncle?!"

All the attacks are not as aggressive as the last sentence of the uncle.

Jiraiya looked at the little ghost in front of him in a daze, and he didn't know what the hell he was talking about.

But there are only two sentences I understand, the first one is that there is no way to promote the secret method of spraying toad immortals to everyone, this is really no way, and the objective reality does not allow it.

But the second sentence made Zilai a little annoyed. Who's the uncle? Although he said that he had indeed brought out ninjas such as the Water Gate, and even the other party had begun to become a ninja, he was still in his prime! How is it an uncle!

"Hey! Gremlin! Hurry up and take back your words! Apologize to the Myoki Mountain Secret Method and me! Where am I so old! ”

"Only an old man cares about his age."

"Damn!"

The two people, one big and one small, stared at each other, as if some kind of electric spark was faintly rubbed.

On the one hand, there is the veteran ninja Jiraiya, who has the advantage of mastering the immortal mode and age, and on the other hand, Kakashi, the new genius of Konoha Hachi, is in charge of the development of the blood suit and the static blood suit at a young age.

No matter what angle you look at, there seems to be a tendency on both sides to be needle-to-point. Although the source is that one ninja is disrespectful to the old, and the other does not have the meaning of respecting the old and loving the young, the two sides are so directly linked.

And when Aizen opened the door and walked in, he saw such an inexplicable scene.

"Ah, Jiraiya-sama, and Kakashi-kun, did you have a good chat?"

"Yes! How can you be angry when teasing a child! ”

"Not at all."

Faced with two diametrically opposed answers, even Aizen was stunned for a moment.

Kakashi in front of him turned his head away with an indifferent expression, and Jiraiya grinned a little reluctantly and tried to touch Kakashi's hair, but Kakashi hid behind Aizen with a teleportation technique.

This familiar technique made Jiraiya stunned for a moment, and just as he wanted to ask, he saw Aizen push his glasses, and explained very gently to Kakashi behind him.

"Jiraiya-sama, Kakashi-kun is a rare genius in technology development, and many things are actually impossible to develop and popularize without the existence of Kakashi-kun. Even a child can use a blood-moving suit, and it doesn't affect it. What this means, Jiraiya-sama should be well aware. ”

"Huh? Ah, that's right, but the immortal mode of Miaomu Mountain is very powerful, don't you really plan to learn it? And the instantaneous step just now, which was also developed by you? ”

"For the former, we don't plan to learn. Because just like Kakashi-kun said, no matter how powerful the secret method of Mt. Mioki is, we can't popularize it. ”

Lan Zhan looked at Zilai and shook his head with some regret, and explained very gently:

"As for the latter, it is an instantaneous step that was developed in reverse based on the information provided by the three ninjas. The other party has already shown all the theoretical principles, and Kakashi-kun is a genius, so it is only natural that he can successfully reproduce it. ”

“……”

So why can't I?

Looking at the seven-year-old child's stinky face, Zilai also wisely swallowed this sentence into his stomach.

People are not the same, and this has been understood for a long time. But a seven-year-old child is actually stronger than his own three ninjas......

As if realizing the root of Jiraiya's somewhat complicated expression, Aizen, who was walking in front, suddenly asked in a low voice:

"I'm going to discuss with Kakashi-kun about development and lecturing next, if Jiraiya-senpai doesn't mind......?"

"Oh! Let me hear it too. I'm quite curious about what kind of technique can make you feel so much stronger than the secret method of Miaomu Mountain. Tell me upfront, if there's any mistake, I'll point it out mercilessly, right? ”

"That would be great, and I just need a senior in this area to point out my mistakes. It's always a bit negligent to do it behind closed doors, thank you very much. ”

So I'm going to get started.

He bowed slightly to the somewhat embarrassed Jiraiya, who seemed to be wearing a high hat, and Aizen wrote a series of words in the air.

This hand also showed a surprised expression.

Anyone can use chakra to leave a mark in mid-air, but if it is as condensed as it is now, not everyone can do it.

With the ability to shinobi, can you really do something like this small miracle? Even if it's me now, I'm afraid there's no way to do this kind of thing, right?

After writing a series of words in mid-air, Lan Zhan turned to look at the two people in front of him, and then looked at the golden hair not far away, and after revealing a gentle smile, he looked at everyone and whispered:

"What I'm going to discuss today is the possibility of chakra and how to use it."

"It's just a discussion, so please feel free to speak."

"Including you, Watergate-kun."

Placing the chakra frozen in mid-air in front of him, Aizen pushed his glasses, looked at the three figures who were surprised and inexplicable, and smiled slightly.
