Naruto's strongest shock

Konoha Hokage Building, outside the meeting room.

Naito Yu was not interested in the content of the meeting at all, but was interested in continuing to detect the situation of the entire Hokage Building with shock wave induction.

Naito Yu tried to see if he could let the shock wave penetrate into the barrier, and directly obtain the information of the real sealed book.

What surprised Naito Yu was that his shock wave induction could completely penetrate into the barrier!

But unfortunately, Naito Yu could not detect the contents of the closed sealed book.

Speaking of which, Naito Yu was quite shocked by the sensory enchantment covering the entire Konoha. In the original book, when Payne invaded, he depicted it a little bit, but he didn't feel anything.

But in Konoha, Naito Yu could not find the existence of that enchantment before, but now Naito Yu can fully perceive it.

It's too big!

How big is the leaf?The scope of the death forest of the Chunin Exam alone is not known how wide it is, and that is only a part of Konoha.

How vast is the enchantment covering the entire Konoha.

This enchantment is probably also the work of the second generation of Hokage Senshou Feijian. It has to be said that in the development of various secret and forbidden techniques, the second generation of Hokage is indeed almost perfect, touching various fields.

After waiting for a while, the meeting inside was over.

After seeing Tsunade coming out, Naito Yu greeted Tsunade first, and immediately found Kato Dan.

"Master Naito Yu?!"

Kato Duan was a little surprised that Naito Yu would find him.

Even though Naito Yu was younger than him, and he was also a Konoha Jōnin, only one level lower than the elite Jōnin, Naito Yu's achievements on the battlefield made him still respect Naito Yu very much.

"Come with me, I have something to do with you."

Naito Yu nodded at Kato Duan, spoke softly, and immediately walked towards Konoha's back mountain.

Although Kato Duan felt a little strange that Naito Yu wanted something from him, he still nodded and followed Naito Yu respectfully.

The two quickly walked to a remote area where no one was there.

"It's like this. The ninjutsu you are best at killing enemies is the technique of spiritualization. I am more interested in this technique, and I am currently trying to study it."

Naito Yu stopped in his tracks, turned around and looked at Kato Duan.

Kato Dan is also a very smart person, so he understood it instantly, and said: "So that's the case, Master Naito Yu wants me to demonstrate the technique of spiritualization?"

"Ah."

Naito Yu nodded.

Kato's tense expression suddenly relaxed, he couldn't help but smiled, and said: "Of course this is no problem, I am very happy to help Naito Yu-sama with this."

"Master Yu Ye, I will slow down the speed and demonstrate it carefully, but this technique is very special. Even if I slow down, it may be difficult to see clearly, because... how should I put it, it involves invisible and formless things. spiritual realm."

While speaking, Kato Dan began to make seals.

The technique of spiritualization is not a secret. Kato Jun has defeated many enemies with this technique, and the person who wants to watch is Naito Yu, so he will naturally not hide anything.

It was so easy, and it was a bit beyond Naito Yu's expectations. Naito Yu originally thought that if Kato was unwilling, he might have to force him to fight before he could use it.

Speaking of it, Kato Dan's character seems a bit like Namikaze Minato, but not as good as Namikaze Minato.

hum! !

In the blink of an eye, Kato finished breaking the seal and let out a low shout.

Chakra suddenly surged on his body, but this chakra flowed completely different from the general ninjutsu. The flow of ordinary ninjutsu was undoubtedly outside the body, but the chakra of the spiritualization technique was restrained, even for a moment. It seems to disappear inside the body.

Naito Yu's eyes can't see clearly, but Naito Yu's shock wave sensor can clearly perceive the direction of Chakra's flow and the soul that is finally spirited out.

The soul transformed by the spiritualization technique can be seen with the naked eye. This trick can even be used when the reincarnation of the filthy soil is lifted and the soul is about to ascend to heaven, to force one's soul to stay.

"Sure enough... Does the technique of spiritualization itself have the effect of strengthening the soul?"

Watching Kato Dan displaying the technique of spiritualization, and a body in the state of a soul flying out of the body, Naito Yu muttered to himself.

Since Orochimaru can take other people's bodies, there is no doubt that his soul should be stronger than those people, so he can forcibly suppress and devour other people's souls.

Although it caused his soul to be broken, it was just a side effect of reincarnation.

Kato's soul is undoubtedly stronger, but in Naito Yu's view, it is completely inferior to Uchiha Madara.

Uchiha Madara can forcibly use the spiritual energy, that is, the soul, to control the scattered body of reincarnation of the reincarnation of the reincarnation of the reincarnation of the reincarnation of the unclean soil under the condition that the reincarnation of the unclean soil is released, and finally untie the reincarnation of the unclean soil by himself, completely out of control. It's just unbelievable.

"That's about it."

Kato Duan, who was in the spiritual state, spread his hands at Naito Yu, and then controlled his spirit body to fly back into the physical body.

Naito Yu nodded to Kato Duan, and said, "Well, thank you very much."

After finishing speaking, Naito Yu lowered his head and fell into deep thought.

And Kato looked at Naito Yu's appearance, and didn't bother him when he was born, and left silently, leaving Naito Yu here alone to continue to comprehend the art of spiritualization.

Time passed quickly, and a few months passed in a blink of an eye, Naito Yu finally fully understood the art of spiritualization, and was able to display it.

However, using this trick in terms of attack obviously doesn't mean much to Naito Yu. Naito Yu hardly needs any active skills or secret arts.

What Naito Yu needs now is passive skills, such as the special secret technique that can strengthen oneself like the secret technique of thunder escape body forging.

The technique of spiritualization itself has the effect of strengthening one's soul, but the degree of increase is very low. After all, the essence of this move is to attack.

Therefore, Naito Yu tried to develop the technique of spiritualization in another direction, that is to strengthen one's own soul and change its essence.

This is much more difficult.

When transforming the real Bamen dunjia before, there was Matt wearing it by his side to verify and discuss, but to develop soul-like techniques, you need to explore and move forward completely by yourself.

Fortunately, Naito Yu is a traveler from another world after all, and he still has an extraordinary talent for developing ninjutsu, and he hasn't made any progress during this period of time.

Another point is that Naito Yu discovered his own soul when he was able to perform the spirit transformation technique, which was much stronger than Kato Dan!

Not only because Naito Yu is stronger than Kato, but also because Naito Yu himself is a time traveler, and the soul itself is stronger than the natives of this world.
