Naruto's strongest shock

In the blink of an eye, another half a month passed.

Naito Yu has completely cultivated the first stage of the Thunder Dungeon Secret Technique to a perfect level, and if he wants to go further, he must obtain the second stage of cultivation methods.

And after practicing the first stage, Naito Yu's body will not have obvious lightning, at most there will be some subtle arcs that cannot be seen unless you look carefully.

Naito Yu reckoned that only after reaching the second stage would it be possible to have the Raikage Cloak that was attached to the body like the Fourth Raikage and the Third Raikage.

The first stage reached the level of perfection, Naito Yu's skin and some flesh and blood have been strengthened and increased a lot, his body has also gradually matured from immature, and his skin color has a little bit of healthy bronze.

You know, Naito Yu is only about ten years old now, but physically, he already looks fourteen or fifteen years old.

It's not just that the people in Naruto World are precocious, but also because they practice physical skills.

The growth of the body has greatly increased Naito Yu's progress in the cultivation of the true eight gates dunjia.

Originally, if Naito Yu wanted to reach the level of opening the fourth door of the True Eight Gates of Dunjia, at least he would have to practice uninterrupted physical skills for about a year, and he could almost reach the standard.

And coming to the battlefield of the Second Ninja World War, it is simply impossible to have too much time for practice!

Just like now, Naito Yu spends little time teaching Konan and Yahiko to practice, and he also doesn't have much time to practice. He still has to go out constantly to hunt and kill ninjas and scouts from other ninja villages.

It can be said that in this kind of battlefield, one may not be able to practice to the extent of opening the fourth door in three to five years.

But the first stage of the secret art of thunder escape body forging directly compressed this process.

It has been several months since Naito Yu came to the Land of Rain, and the cultivation of the secret technique of body training by Lei Dun has made Naito Yu the equivalent of practicing body skills non-stop for the past few months!

Naito Yu reckoned that if he could get the second stage of the Lightning Escape body training secret technique, he might only need to practice half of it to reach the level of opening the fourth door.

However, this, like the Kusanagi sword, is difficult to obtain in a short period of time.

After shaking his head, Naito Yu felt that regardless of whether the remaining Kusanagi sword was in Hidden Sand Village or not, he had to target the following on this battlefield. Anyway, as long as the Kusanagi sword approached a certain range around him, he would have a reaction.

If he couldn't find it on the battlefield, Naito Yu would sneak into Hidden Sand Village during or after the war.

In addition, Naito Yu will definitely go to Yunyin Village. Since the Thunder Dungeon body training secret technique has such a large increase, Naito Yu is bound to win it.

"call!"

Exhaling a breath, Naito Yu stood up, and the traces of electric arcs on his body disappeared instantly.

Then, Naito Yu walked out of the room, turned around, and looked at the progress of Konan and Yahiko's cultivation.

Because Xiaonan and Yahiko are about the same age as him, their cultivation speed is much faster than those of the ninja school.

In this world, it is not that the younger you are, the better you are practicing, because chakra extracts energy from body cells, so you have to reach a certain age to start practicing.

Konan and Yahiko happened to be in the best age for cultivation.

So their current chakra levels are almost close to the level of Genin, and Xiaonan's original paper escape ninjutsu has finally been developed.

With ninjutsu, basically even if they have the strength of ninjutsu, it is difficult for ordinary people to threaten them.

Yu Naito nodded noncommittally, unable to say whether he was satisfied or not.

At the same time, what makes Naito Yu a little helpless is that during this time, Naito Yu has been trying to find traces of Nagato, but he has not found anything.

Nagato seems to be completely missing!

This made Naito Yu very puzzled.

As usual, Naito Yu went out again and came to a nearby town.

The Land of Rain is not big, and there are not many small towns, so there will be Konoha's scout ninjas in almost every small town.

It is worth mentioning that Naito Yu killed Chiba, and when the news came back to Konoha, Hiruzaru Sarutobi was silent for a long time, and finally asked Naito Yu what else he needed.

What Naito Yu needed was of course the second stage of the Lightning Dungeon Bodybuilding Secret Technique, but the news fell to nothing, and Hiruzaru Sarutobi didn't get a reply. It is estimated that Konoha really didn't have one.

Turning around in the small town, Naito Yu casually eliminated a few ninjas from Yuyin Village, and at the same time killed a Yanyin scout who was discovered by him.

Then, Naito Yu went to find Konoha's ninja who was responsible for delivering the news.

Sending messages on the battlefield is very special, and for a special Anbe like Yu Naito, sending messages is even more special.

The oldest method of scroll delivery is used.

A special method must be used to open the scroll, otherwise the scroll will naturally be destroyed, erasing its contents.

This is a method of absolute secrecy.

Naito Yu has not received news from Konoha for a long time, most of the time he passed the news to Konoha.

This time, he received a message from Konoha.

Coming to the corner and cracking the special seal on the scroll, Naito Yu casually glanced at the contents.

But it was this glance that made Yu Ye's eyes suddenly focus, and a sharp aura emanated from his whole body.

Naito Yu's identity as a ninja was almost directly revealed, but Naito Yu didn't care at all.

Even, he couldn't help but use force with his fingers, almost crushing the scroll.

The information on the scroll is: Tsunade led the Konoha team to encounter an ambush by Iwagakure and was forced into the hinterland of the Land of Rain. The situation is critical and Naito Yu needs to rescue him as soon as possible.

Tsunade's strength is at least elite jonin, or even quasi-kage level.

But now, the word used here is not support, but rescue!

The difference between one word and the meaning is completely different!

This shows that the situation Tsunade encountered is a real crisis, otherwise such words would not be used.

Taking a deep breath, Naito Yu destroyed the scroll and left directly.

When Tsunade encounters a crisis, Naito Yu will never sit idly by. The plot has been changed too much by Naito Yu, and Naito Yu can't predict whether Tsunade will die if he doesn't help.

So he has to go.

A general direction was given on the scroll, and the forward route happened to pass through the place where Naito Yu, Xiaonan and others lived.

Therefore, Naito Yu decided to speak to Yahiko Kominami first.

If the scroll gave the opposite direction, Naito Yu might not even notify Konan and Yahiko, and just go straight to the position and location marked on the scroll.

Without consuming too much energy, Naito Yu used full speed and returned to the place of residence in a short while.

Konan and Yahiko are still practicing.

Naito Yu simply told them that he would leave temporarily for a period of time, and when he left, let them pay attention to hiding himself, and it was best to live directly in a nearby town.

They are no longer ordinary people with no power to restrain chickens.
