Konoha: The seal art teacher of the ninja school

After Xia Yan successfully built the prototype of the Chakra Intelligent Brain, he began to develop rune ninjutsu.

To put it simply, it uses the computing power of the prototype machine and uses various algorithms to analyze and convert the seal language used in ninjutsu into rune language.

Unlike most ninjas who only know what various ninjutsu are, but don't know why.

Being completely transformed into rune ninjutsu means that there is no secret to Xia Yan about that technique.

The Muyin technique is just a basic operation.

What's more important is that Xia Yan can modify and customize these rune ninjutsu at will to make them more in line with his own wishes.

For example, as long as Xia Yan wanted to, let alone carving a dog's head on a Tuliu wall, there would be no problem carving a picture of Along the River During the Qingming Festival on it.

The projection technique and inspiration he used in class were also originally created through the analysis of the Three Body Technique.

After the analysis of the Three Body Technique was completed, the next thing Xia Yan analyzed was naturally the Shadow Clone Technique with great potential.

It's a pity that the Shadow Clone Jutsu, as a B-level ninjutsu, is not as easy to fully analyze as the E-level ninjutsu like the Three Body Jutsu.

Until a few days ago, Xia Yan's analysis progress of the Shadow Clone Technique was still stuck at 66.6%, making it difficult to make any progress.

The main reason why it is difficult to continue analyzing is still an old problem, because Xia Yan did not master enough runes.

Therefore, he cannot yet express the unparsed parts in the form of runic language.

This is why Natsuhiko is determined to return to the ninja school and become a teacher.

The purpose is to collect more original runes to break through the bottleneck of analyzing ninjutsu.

Although the analysis of this shadow clone technique has not yet been completed, Xia Yan still gained a deeper understanding of it in the process of analyzing this technique.

These understandings allowed Xia Yan to find loopholes in the shadow clone technique, which he could use to fine-tune it, so that he could no longer only create shadow clones that were exactly the same as himself.

And the three little ones in front of him were exactly the things he got out of a bug.

As we all know, shadow clones will continue to consume chakra while maintaining their own existence.

And Natsuhiko is also very confident about his meager amount of chakra.

Therefore, in order to create more clones and maintain them longer, his approach to adjusting shadow clones is very similar to his approach to sealing.

That means saving when you can.

When I look at the mobile phones he bought in his previous life, he bought the youth version instead of the standard version, and the beggar version instead of the youth version.

In view of his shadow clone, Xia Yan spends most of his time doing research work, which is just pure mental activity.

Therefore, those charming and eye-catching chest muscles, eight-pack abs, arm muscles, and mermaid lines have no use at all, and are not worth consuming precious chakra to maintain.

Therefore, Xia Yan also customized a true "youth version" of the shadow clone technique for himself.

He first created three small balls similar to his own chakra brain, and drew a special interference circle on them.

Then when Xia Yan uses these three small balls as media to perform the Shadow Clone Technique, the interference spells above will affect the operation of the Shadow Clone Technique, and a bug is stuck, causing the Shadow Clone Technique to reflect him.

What he looked like when he was three years old.

Why choose three years old?

This is because the brain weight of babies at this stage is close to the weight of adult brains and they can basically take care of themselves.

This is the most cost-effective form that Xia Yan determined after many attempts.

Of course, Xia Yan has also tried other routes, such as directly dividing a few brains and throwing them into a petri dish to let them think about life.

Brain in a Vat Warning!

Unfortunately, Xia Yan’s idea did not succeed due to insufficient technology.

I don’t know if this is luck or misfortune...

This new version of the Shadow Clone Technique developed by Xia Yan allowed him, who could only maintain one clone, to be able to maintain three clones at the same time.

The efficiency is directly doubled!

However, his magically modified shadow clone technique is not without its shortcomings.

Although these clones are less consumed, their personalities seem to have suffered psychological regression due to physical changes, and they have become as out of tune as children.

And it may be because Xia Yan did not fully master this technique and only used the interference array to achieve this effect.

The slight differences in the materials and rune spells of the three small balls eventually led to different deviations in the personalities of the three clones.

Xia Yan studied for a long time but couldn't find a solution, so he could only let it go.

Anyway, as long as they can complete the tasks assigned by Xia Yan, he won't care too much about their minor problems.

At the same time, these clones were created by simulating his childhood.

Therefore, Natsuhiko also called this ninjutsu the Infant Clone Technique.

…

Xia Yan in the entrance hall finally got rid of the stalking of the three baby clones.

Although these three little things basically have no fighting ability, one punch should make them cry for a long time.

But the problem is that Xia Yan doesn't dare to use too much force against them.

If the clone is accidentally released, their memories will suddenly return to their original body.

You must know that they did a lot of research during the day, and the amount of memory suddenly poured into their brains. Even if Xia Yan was not a fool, it would be difficult.

These three little devils obviously saw this and were confident.

So the naughty kid is really annoying, even if it is actually his former self.

Xia Yan sighed helplessly and walked towards the study.

I'm just getting by, how can I leave?

Seeing Xia Yan's actions, the three little ones also quickly lined up and followed him, pulling the clothes of the person in front to start the train, and imitating the sound of the train.

"Sssssssssssssssssssssssttssssssssssssssssssss of bangs,sssssssssssssssssssssssssssssssss"

The little guy in red is still asking: "Why don't you follow me when I call you? You are not gregarious at all!"

The little guy in blue encouraged: "It doesn't matter. If you anger him a few more words, and make him so angry that his head is smoking, wouldn't it be more like a locomotive?"

The little guy in green is still indulging in the cosplay carriage: "Boohoo boomboom ~ boombooboo boomboom..."

Xia Yan walked into the study with a black hair on his head.

You can see bookshelves placed on all sides of the room, densely packed with various books and scrolls.

These are all kinds of classics on sealing techniques and runes that Xia Yan has collected from various places over the years.

Most of the 233 original runes he has mastered now were excavated from here.

In fact, speaking of it, the fact that he was able to collect so many books must be attributed to the fall of the Kingdom of Whirlpool.

The Uzumaki clan of the Kingdom of Whirlpools has been famous for its superb sealing techniques since ancient times, and the clan naturally has a large collection of sealing technique classics.

And this also laid the foundation for the demise of their clan.

Because since Senju Hashirama assigned the tailed beasts to other villages, the importance of sealing techniques has greatly increased.

In order to better control the tailed beast in their hands, and to prevent others from using sealing techniques to deal with their Jinchūriki, the three major ninja villages, Kumogakure, Kirigakure, and Iwagakure, joined forces with many smaller ninja villages to launch a sneak attack on the Country of Whirlpool.

, eventually destroying it.

It can be said that Dazhu's miraculous operation of allocating tailed beasts caused misery to his wife's natal family.

As for those books on sealing techniques...

Although most of the valuable classics were divided up by the ninja villages that besieged the Kingdom of Whirlpool.

However, there are also many books that have flowed into the black market, which has also led to an increase in the average level of sealing techniques in the ninja world.

It's really a whirlpool, and the ninja world is full.

However, when Xia Yan started collecting these classics, many years had passed since the fall of the Kingdom of Whirlpool.

So even in the black market, there are only some scraps left, which cannot fully meet Xia Yan's needs.

Whenever Xia Yan heard that so-and-so had picked up precious sealing techniques in the black market, he was very envious and regretted that he had not been born a few years earlier.

In addition to the normal furnishings in the study room, there are three small desks placed in the corners, which are also filled with various books, notes and talismans.

Xia Yan bought this specially for the three clones with short hands and short legs.

Xia Yan sat on the main seat in the study, looked at the three little ones standing in a row in front of the table, and slowly said:

"Okay, now you can start reporting on the progress of your work today."
