"Spiritualization?"

In the Hokage's office, Sarutobi Hizashi raised his eyebrows in surprise when he heard the surgery that Natsuhiko had chosen.

The so-called spiritualization technique is a terrifying ninjutsu that can temporarily separate the caster's spirit and body to form a special "living being" and cause the enemy's spirit to collapse and die through possession.

Tsunade's lover, Kato Tsunade, who died in World War II, is good at this technique.

"Natsuhiko, are you sure you want to choose this technique?"

Sarufei Ri thought about it, but decided to remind, "Choosing those high-level sealing techniques should help you even more." ”

He was a little worried that Xia Yan would be too ambitious.

After all, after seeing many potential ninjas who have made great achievements, in order not to waste the opportunity, he chose an ultra-difficult ninjutsu like the Spiritualization Technique, but it took several years to fail to get started, but instead wasted the years, and everyone was lost.

He had high expectations for Xia Yan, but he didn't want Xia Yan to repeat the mistakes of these people.

As a result, he saw Xia Yan showing a slightly self-contained smile.

"No need, Hokage-sama."

"Because my master said that she can do the sealing techniques in the Book of Seals, so I don't need to choose those."

When the three generations heard this, their eyes suddenly widened.

What a big breath!?

Even as a doctor of ninjutsu, he didn't dare to say that he had completely mastered all the sealing techniques on the Book of Seals.

In today's ninja world, I'm afraid that only one can boast of this kind of seakou......

Thinking of a certain possibility, Ape Fei Ri Slash was shocked and said:

"It's hard to ...... Could it be that Mito-sama ...... she?"

Xia Yan grinned: "Yes, Mito-sama, she just accepted me as a disciple this morning. ”

Haha, he will also have a backer in the future.

I just don't know when this VIP can be renewed......

“……”

Ape Feiri leaned back in the chair, his expression a little helpless.

Mito-sama, what is this doing?

Why is such a big thing, and he doesn't know him.

Although the inheritance of master and apprentice in the ninja world does not pay much attention to the issue of generation, Sarutobi Rizap felt uncomfortable when he saw that this young Xia Yan was theoretically a member of his generation.

What's more, he wrote to Orochimaru, who was still sitting on the front line of Yunyin, a few days ago, and told him that he had already helped him find a candidate for an apprentice!

Unexpectedly, within a few days, his scheduled apprentice became his junior brother!

However, since this is Mito-sama's intention, it is natural that Sarutobi has no way to put his beak.

After sighing helplessly, he added:

"Since Natsuhiko has become a disciple of Mito-sama, there is really no need to choose the sealing technique."

"But since you've been given such a precious opportunity, shouldn't you put all your energy into sealing now?"

"The art of spiritualization is a super difficult S-level ninjutsu, and if you want to learn it, it will definitely waste a lot of your time, and the gains outweigh the losses."

"As I said before, this reward can be redeemed at any time, so you don't have to rush it."

Ape Fei Ri Slash expressed in a very euphemistic way, "Xia Yan, you kid, why don't you learn more about the sealing technique before Mito-sama dies, what kind of bullshit spiritualization technique can you learn!" ".

Then he said: "And this spiritualization technique also has a lot of flaws, even Kato Xuan, who is proficient in this technique, finally died in the process of using this technique." ”

Speaking of which, Ape Fei Ri couldn't help but be a little gloomy.

After all, Kato Tsuru is also a child with the qualifications to become a Hokage, but it's a pity that he died too early......

Even Tsunade suffered from hemophobia and gradually gave up on himself.

Seeing that the three generations suddenly looked depressed, Xia Yan scratched his head and felt a little helpless.

How do you feel as if you are heinous if you choose this technique?

Xia Yan had no choice but to hold his hand and throw out the prepared rhetoric:

"Hokage-sama, don't worry, I know that I have an average talent in ninjutsu, so I don't expect to master this technique so quickly."

"Even if I master it, I don't plan to use this high-risk ninjutsu in combat."

"I chose this technique just to study and see if I could apply some of its functions to teaching."

"Pedagogically?"

Ape Fei Ri finally came back to his senses and said in slight surprise.

"Not bad."

Natsuhiko smiled: "Hokage-sama, you also know that although the training clothes I invented, although they can copy the body movements and the flow of chakra, they can't be used to copy ninjutsu because they can't copy the subtle changes inside chakra. ”

Ape Fei Ri slashed his head slightly, indicating that he knew.

In the past, he didn't pay much attention to the school affairs when he handed over the affairs of the school to Lake Biwa, but since Lake Biwa mentioned the training clothes that are said to improve the level of physical skills a few days ago, he naturally has a certain understanding.

So he couldn't help but admire: "Even if it can only be used to copy the body technique, it is a very remarkable invention." ”

"In addition, there is also the broadcast gymnastics that is used to widen the meridians, which makes the role of this training uniform play the maximum."

"Let me start to look forward to how far the strength of the students who will graduate in a few years will improve."

"-But what does this have to do with the Spiritualization Technique?"

Natsuhiko explained, "Because the idea of using a perceptual circle to copy ninjutsu in the training suit has reached a bottleneck, I plan to try to start with another way of thinking and see if I can achieve the desired effect." ”

"To put it simply, it is to apply the principle of spiritualization to the training uniform, so that teachers can directly use the students' bodies to perform ninjutsu in the form of possession, so that they can experience the essentials of magic and speed up the progress of learning."

The corners of Ape Feiri's mouth twitched slightly when he heard this, and he didn't know for a while whether he should be speechless or relieved.

After all, the terrifying S-level forbidden technique of spiritualization, Xia Yan actually planned to use it on students?

Not to mention, as a doctor of ninjutsu, Sarutobi Hizashi quickly judged that this idea seemed to be somewhat feasible.

After all, thanks to the magical chakra, in the ninja world, although there are not many ninjutsu involving the spirit and even the soul, it is not something that cannot be learned.

For example, the Mind Transformation Technique, which is similar to the Spiritualization Technique, is actually only C-level difficult to learn.

Although there is a reason for the constitution of the Yamanaka clan, it is quite telling.

The biggest difficulty of the Spiritualization Technique is that it is necessary to completely strip the spirit from the body, unlike the Mind Turning Technique.

This will increase the success rate when breaking the enemy's spirit, or prevent damage from being fed back to your own body when controlling the enemy's body to self-harm.

If it is not used in combat, but only for students, then the requirements for mastery of the spirit art will naturally be greatly reduced.

If you add various safety mechanisms to your training clothes, the risk can be further reduced.

So Xia Yan's idea is theoretically possible.

Even Ape Fei Ri Slash was still thinking that maybe he could directly let the people of the mountain clan test it.

It's a pity that the ninjas of this type of secret art family have become difficult to master other types of ninjutsu due to the cultivation of secret arts, so even if they succeed, they can't teach their students much.

You can't teach the secret art of the family, right?

So it seems that it still has to be developed by Xia Yan.

Ape Feiri pondered for a long time, weighed the pros and cons, and then slowly nodded and smiled:

"I have to say, Xia Yan, your idea is indeed quite feasible."

"But what makes me even happier is that when you were exchanging ninjutsu, you were still thinking about how to improve the level of your students."

"This is enough to prove that you are a good boy who truly has the will of fire."

"It's no wonder Mito-sama made an exception to accept you as a disciple."

"Hmm...... Since you have such an idea, then I will not stop it...... In addition to the art of spiritualization, I can also give you a copy of some related information as a reference. ”

"Thank you, Hokage-sama."

Xia Yan was overjoyed when he heard this, and thanked him.

"But—"

Ape Fei Ri still couldn't help but remind, "Until I am sure that your invention is safe, Xia Yan, you can't use students for experiments." ”

After all, when it comes to matters involving the realm of the soul, you can't be too careful.

Not to mention his second son, Asma, who is also in Xia Yan's research group.

"Of course." Xia Yan nodded.

"Alright, let's go, I'll take you to the Book of Seals." Ape Flying Sun Slash stood up from his seat.
