A certain scientific Naruto

Ninjutsu should be learned systematically, so the next ninjutsu will be an upgraded version of the Shadow Clone Jutsu, the Multiple Shadow Clone Jutsu. Kushina scratched her hair, and then thought hard about it. A ninjutsu that Hagoromo should be taught.

Multiple Shadow Clone Technique. Although it is an A-level ninjutsu, it is only an enhanced version of the Shadow Clone Technique. It should not be difficult to practice.

Hagoromo glanced at Kushina silently and said to himself that the difficulty of practicing the multiple shadow clone technique is not high, but it is a forbidden technique and will consume tons of chakra, okay? Besides, with a physique like his own, it is basically The Shadow Clone Technique is definitely enough, and his fighting style will not be useful in multiple Shadow Clone Techniques.

But since Kushina wants to teach him, he should learn it honestly. Anyway, as long as he controls the amount of chakra, he should be able to avoid the danger caused by this technique.

The multiple shadow clone technique requires the distribution of a large amount of chakra at one time, so if the control is not good, it will cause injury to the user, but Hagoromo does not think that such a problem will occur based on his own control ability.

But he still said one more thing, Um, Kushina-sensei, the multiple shadow clone technique is considered a forbidden technique, right? Is it okay to leave it to me?

The Multiple Invisibility Clone Technique is indeed a forbidden technique, but I want to teach you. Do you think the third generation will have any objections?

Hagoromo wanted to say very much, Kushina-sensei, you misunderstood me. I'm not talking about the Hokage's permission. I mean, this ninjutsu won't kill me, right? What everyone is worried about is different, okay?

Fortunately, Kushina continued to explain, Although this ninjutsu is a forbidden jutsu, the scope of the ban is only for ninjas below jounin. For ninjas at the jounin level, it is nothing. Through my perception , I think your chakra level is pretty average, so it’ll be fine, probably.”

Hey, hey, that's well said. What does the last one mean? Will there still be risks if not done well?

The difference between the multiple shadow clone technique and the shadow clone technique lies in the amount of chakra running in the meridians. If the amount of chakra required for the shadow clone technique is 1, then to separate three clones at the same time, 3 chakra amounts are needed to form the seal. It is easy to understand that it passes through those meridians at the same time. If the clones that are separated at the same time are only single digits, it is not too difficult and not dangerous.

But on the contrary, if you want to separate more than ten clones, the difficulty can be imagined. If you want to separate more than a hundred or a thousand clones... only bugs like Uzumaki or Senju can do it. Hagoromo doesn't need to count on it. Yes, although his chakra capacity is good, it is compared with ordinary people. If the comparison object is replaced by a whirlpool, then he will definitely be injured silently.

Watch it... Kushina demonstrated for Hagoromo again.

And Hagoromo is a person who knows how to make choices. When he practices the multi-shadow clone technique, the number of clones at a time will never exceed 5. Under such limited circumstances, he can be considered to have mastered this technique.

Very good, you are very calm. Kushina patted Yuyi's shoulder and praised, Well, let me teach you another ninjutsu today. Of course, this is also the last ninjutsu today, and it is still the system of the clone jutsu. Yes, the name is Shuriken Shadow Clone Jutsu.

This ninjutsu should be the copyright of the Third Hokage. Is it really okay to be so unscrupulous? Hagoromo couldn't help but be a little suspicious.

In fact, there is a problem, but that is for ordinary people. If it is for Kushina, there is no problem at all.

In fact, Kushina felt a little guilty at this moment. What she felt guilty was not the infringement of the Sandaime's copyright, but the speed at which Hagoromo learned ninjutsu. If she didn't limit it, the ninjutsu she had mastered might soon be learned by her disciples. Come on, when the time comes there will be nothing to teach, how miserable it will be.

With such a student on the stand, Kushina was not just happy now, but also a little bit tragic.

But she thought of Kakashi, whom Minato had been praising, and hummed, gritting her teeth, she still had to teach Hagoromo.

In fact, Hagoromo is already very satisfied. When Kushina comes out, what teacher will teach him three advanced ninjutsu every day?

Of course, with his current amount of chakra, it is simply not enough for him to perform too many advanced ninjutsu in battle, but his curiosity makes it difficult for him to give up the pursuit of advanced ninjutsu.

The higher the level of ninjutsu, the more mysterious it is and the greater its attraction to Hagoromo.

In this way, Kushina took Hagoromo to practice while completing her work. At the same time, sometimes due to the Hokage's face and constant persuasion, she would take Hagoromo to do some low-level tasks such as catching cats and dogs.

Time flies by, and unknowingly it has been three months since Hagoromo graduated from the Ninja School. The graduates in the same period have already followed their teachers to the battlefield. Hagoromo even feels that many of them have sacrificed. But he himself has never even stepped out of Konoha's gate.

In this sense, he unknowingly fulfilled his mission as a toy perfectly.

…………

Hey, Kushina-sensei, you seem to be quite happy today. You don't have the sad look on your face at all. Hagoromo said to Kushina in front of him. In fact, because the development of ninjutsu was not going well, Kushina Nai has been irritable for several days, but today her mood suddenly improved. This is indeed a strange thing.

After all, after three months of getting along, Hagoromo already knows Kushina's personality very well.

Is there any new progress in the development of the Four Symbols Sealing Technique?

That's right, in the past three months, Hagoromo has transformed from a rookie to a professional assistant who can assist Kushina in the development of S-level forbidden techniques.

Kushina is responsible for the design of the sealing technique, and Hagoromo is responsible for the data calculation. The two of them work together very well.

The Four Elephants Seal Technique can be said to be an extreme variant of the Four Elephants Seal. This is an S-level mission assigned by Konoha's seal research institute. The original requirement is that this technique is used to die with the enemy. When a ninja is about to die, Activating this technique can seal surrounding enemies together.

However, Hagoromo put forward a different point of view. He believed that this greatly limited the scope of use of this technique. If it could be used on a scroll instead of the human body, it could become a very aggressive sealing technique.

Kushina found her disciple's point of view very interesting, and the requirements of this S-level mission were too low on her level, so she followed Hagoromo's instructions to improve this ninjutsu.

However, the difficulty of this ninjutsu became apparent only after starting to practice it.

So Hagoromo often had to face the crazy Kushina.
