Konoha's Strongest Technician

"By the way, Minato-sensei. Last time I heard that Sister Kushina said that you were developing Muji Ninjutsu. Can you let me take a look?"

Kakashi asked suddenly.

He was a little curious about Rasengan, a ninjutsu that Naruto learned in a few days in the original work. Why did it take Minato-sensei three years to learn it?

"Oh, that, teacher, I haven't finished it yet."

Minato replied with a silly smile.

But now that Kakashi asked, he raised his right hand and briefly showed the current results.

"Minato-sensei, are you forcibly compressing chakra into a sphere?"

"The internal structure of a forcibly compressed chakra sphere must be unstable."

"When it explodes, won't it hurt you as well?"

Looking at the chakra ball in Minato's hand, Kakashi knew that he had gone into the wrong direction.

In the original work, Minato-sensei’s Rasengan was inspired by the Tailed Beast Jade.

As for the tailed beast jade, to put it bluntly, the tailed beast compresses its extremely huge chakra to the limit and then launches it out, producing the power of a nuclear bomb!

But normal humans are far from the level of tailed beasts in terms of chakra volume and compression strength!

After all, the tailed beast itself is a huge ball of chakra!

"Ahaha, yes, so the teacher is also worried about this now."

Minato scattered the chakra ball in his hand and scratched his head, looking a little dazed.

Minato has actually been conducting tests during this period.

But he soon discovered that if he directly compressed the chakra to the limit and detonated it at close range, the problem pointed out by Kakashi would occur.

If the chakra ball is thrown like a tailed beast, the unstable ball that is out of control of the palm will easily scatter during flight, resulting in a sharp reduction in power and difficulty in ensuring the hit rate.

But if the weight of chakra is reduced in order to ensure a stable structure, then the meaning of developing this technique is lost.

After all, what he lacks now is the powerful ninjutsu that can match the Flying Thunder God!

"Why don't you, teacher, try to rotate the chakra in the direction of the body's spin to form a stable dynamic balance?"

Kakashi took the opportunity to reveal the method that Jiraiya taught Naruto in the original work.

"That's right! Why didn't I think of that, Kakashi, you are such a genius!"

When Minato heard this, his eyes lit up!

He immediately started trying.

Three minutes later, the first Rasengan in history was born!

Minato's body flashed, and he came to the big tree in an instant, and pressed the Rasengan to the trunk of the tree with one palm.

I saw that the expected explosion did not happen.

Instead, the Rasengan was directly pushed forward and even penetrated the tree trunk, leaving a huge hole directly in the center of the tree.

This kind of power is definitely a Rasengan!

Kakashi saw this and nodded secretly.

Sure enough, this kind of development speed is in line with Minato-sensei's talent!

The reason why it took so long in the original work must be that there was a deviation in the development ideas!

The Rasengan represents the ultimate change in chakra form, and this is the ability that Minato-sensei has mastered.

Now that Kakashi has revealed the key point with one word, it will be done in minutes!

"Kakashi, this technique can be successful so quickly without your help. Why don't you give it a name!"

"Of course, if you can't think of anything at the moment, I can give you a few references, such as the Spiral Flash Turbo Zero, or Visiting the Wind..."

Minato-sensei was very excited to suggest a name for himself, as this was one of his biggest hobbies!

"Ahem, otherwise, let's call it Rasengan!"

Kakashi quickly interrupted Minato-sensei's divergent thinking.

Just kidding, with such an abstract and difficult-to-pronounce name, the battle may be over before I finish shouting it during the battle!

"Rasengan, that's a good name. But I still think..."

Minato-sensei still looked a little unfinished.

"Well, Minato-sensei, I just happened to have developed a new technique, why don't you help me take a look at it?"

Seeing this, Kakashi hurriedly used his trump card, the attention diversion method!

This trick is useful for bandits!

"Oh? Then I really want to take a look."

Minato was indeed intrigued by Kakashi and no longer struggled with the naming of the new technique.

"Chou-mao-shen."

I saw Kakashi forming seals with his hands, and an arc of electricity appeared out of thin air from his right hand.

"Chidori!"

With a loud roar, the electric arc instantly expanded dozens of times, and thousands of birds chirped in unison, emitting a dazzling light!

"This is?"

Minato's pupils shrank.

Although he had enough expectations, Kakashi's new technique still far exceeded his imagination!

Looking at the dangerous cold light on Kakashi's right hand.

Minato was sure that it was a ninjutsu as powerful as the Rasengan!

"Kakashi, did you develop this alone? How long did it take?"

Minato couldn't believe it.

"Yeah, I just did it casually. It probably took about a week."

Kakashi smiled naively.

"o_o...."

Minato was speechless.

It took two months to develop the Rasengan by myself, and it was only with Kakashi's reminder that the key point was achieved.

On the other hand, Kakashi, who is also an A-level ninjutsu, only used it for a week.

Who is the teacher?

However, the better your students are, the higher your teaching level is.

Yes, it is like that!

Minato, who was optimistic by nature, recovered from the violent shock in an instant.

"No wonder you want to practice reaction speed with me. It turns out it's for this technique."

At this time, he had figured out the ins and outs of the matter.

"Originally, I planned to teach you the Rasengan so that you can use it in conjunction with the Flying Thunder God like me."

"Now it seems that you have blazed your own path."

"Maybe it won't take long before you can surpass me."

Minato couldn't help but sigh.

"Well, Minato-sensei. In fact, I have also learned the Rasengan."

Kakashi said, raising his left hand, a meatball that looked exactly like Minato's appeared in his hand.

???

Have you learned this?

Minato fell into a daze for a moment.

Over the years, he has seen countless geniuses, and there are quite a few who were defeated by him!

But no matter how amazing and talented those people are, no one has such a powerful ninjutsu talent!

Such demonic qualifications...

Maybe I will personally train a generation of Hokage!

"Minato-sensei, Minato-sensei?"

"Huh? Oh, I just got distracted, sorry."

Minato came back to his senses and looked at Kakashi with a little more anticipation in his eyes.

"Well, Minato-sensei, I would like to try to combine Chidori and Rasengan. Do you have any good suggestions?"

Kakashi always felt that Minato-sensei's eyes suddenly became much hotter when he looked at him.

He didn't think much and continued to ask his questions.

"Fusion," Minato pondered for a moment, "The Rasengan is the ultimate use of chakra form changes."

"And your Chidori seems to be the ultimate expression of the changes in the properties of thunder attribute chakra."

"Therefore, both of these belong to the category of A-level ultra-advanced ninjutsu."

"And once you combine the two, you can go one step further and become an S-level secret killer ninjutsu!"

"The difficulty of this has increased several times, and even I am not absolutely sure!"

"So, I don't recommend you to try it now, because developing the secret killing technique is extremely vulnerable to serious injury!"

"If you really want to do this, I have only one request, and that is that I must be present!"

Listening to Minato's serious words, Kakashi felt warm in his heart.

Behind that seeming seriousness, there was a deep concern.

"Yes!"
