After Xia Yan succeeded in building the prototype of Chakra Zhi Brain, he began to develop rune ninjutsu.

To put it simply, with the help of the computing power of the prototype, through various algorithms, the sealing language used in ninjutsu is parsed and converted into runic language.

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

Completely transformed into rune ninjutsu, it means that that technique no longer has any secrets to speak of for Xia Yan.

Muji-caster or something is just the basics.

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

For example, as long as Xia Yan wants to, let alone carving a dog's head on the Tuliu wall, there is no problem in carving the Qingming Riverside map on it.

And the projection technique he performed during his class, the revelation was also created through the analysis of the three-body technique.

After the analysis of the three-body technique is completed, Xia Yan's next analysis is naturally the shadow clone technique with great potential.

It's a pity that the shadow clone technique is a B-level ninjutsu, and it is not as easy to be completely parsed as the E-level ninjutsu like the three-body technique.

Until a few days ago, Xia Yan's analysis progress of the shadow clone technique was still stuck at 66.6%, and it was difficult to make progress.

The main reason why it is difficult to continue to analyze is still the old problem, because Xia Yan has not mastered enough runes.

As a result, he was not yet able to express the unparsed parts in runic language.

This is also why Natsuhiko is obsessed with returning to the ninja school to become a teacher.

In order to collect more primordial runes, so as to break through the bottleneck of analyzing ninjutsu.

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

These understandings also allowed Xia Yan to find a loophole in the shadow clone technique, which he could use to fine-tune it, and he was no longer only able to separate the shadow clone that was exactly the same as himself.

And the three little ones in front of him are the things he got out of the BUG card.

It is well known that shadow clones will continue to consume chakras while maintaining their own existence.

And Xia Yan is also very forced on his barren chakra.

So in order to separate more clones and keep them longer, his idea of adjusting the shadow clone is very similar to his idea of sealing.

That is, if you can save, you can save.

Looking at the mobile phone he bought in his previous life, he didn't buy the standard version if he had a youth version, and he didn't buy the youth version if he had a beggar version.

In view of his shadow clone, Xia Yan is conducting research work most of the time, just pure mental activities.

Therefore, those charming and eye-catching pectoral muscles, eight-pack abs, arm muscles, and mermaid line are useless at all, and it is completely not worth consuming precious chakras to maintain.

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

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

Then when Xia Yan used these three balls as a medium to cast the shadow clone technique, the interference technique on it would affect the operation of the shadow clone technique, and a bug was stuck, so that the shadow clone technique reflected his appearance when he was three years old.

Why choose a three-year-old?

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

It is the most cost-effective form determined by Xia Yan 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!

It's a pity that due to the lack of technology at home, Xia Yan's idea did not succeed.

I don't know if it's lucky or unlucky......

The new version of the shadow clone technique developed by Natsuhiko allowed him, who could only maintain one clone, to be able to maintain three clones at the same time.

Directly double the efficiency!

However, his magic version of the shadow clone technique is not without its shortcomings.

Although the consumption of these doppelgangers is small, their personalities seem to have caused psychological regression due to physical changes, and they have become as out of tune as children.

And it may be because Xia Yan didn't fully master this technique, but only used the interference circle to achieve this effect.

The slight difference between the materials of the three balls and the rune form eventually led to different deviations in the personalities of the three clones.

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

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

At the same time, because these doppelgangers are simulating his childhood.

Therefore, Xia Yan also called this ninjutsu the art of infant clone.

……

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

Although these three little things basically have no combat power, they should be able to cry for a long time with a punch.

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

If they accidentally disarm their clones, their memories will suddenly return to their own body.

You must know that they have done a lot of research during the day, and the amount of memory has suddenly flooded into the brain, and Xia Yan is enough to choke even if he is not a fool.

These three little devils obviously saw this point, so they had nothing to fear.

That's why bear children are really annoying, even if it's actually their former self.

Xia Yan sighed helplessly and walked in the direction of the study.

It's okay, what else can you do?

Seeing Xia Yan's actions, the three little ones also hurriedly lined up to follow behind his buttocks, pulling the clothes of the person in front of him to drive the train, and his mouth was still imitating the sound of the train.

"Bang Bang

The little guy in red was still asking: "Why don't you call the body, it's not social at all!" ”

The little guy in blue encouraged: "It's okay, if you are angry with him a few more words, and make him so angry that the top of his head smokes, isn't it more like a locomotive?" ”

The little guy in green is still indulging in the COS carriage: "Bang ~ Bang ......"

Xia Yan walked into the study with a black line.

You can see that there are bookshelves on all sides of the room, and various books and scrolls are densely packed on them.

These are all kinds of books about seals and runes that Xia Yan has collected from various places over the years.

Most of the 233 primordial runes he had now had been excavated from here.

In fact, he was able to collect so many books, and it had to be attributed to the collapse of the Vortex Country back then.

The Uzumaki clan of the Vortex Country has been famous for their superb sealing skills since ancient times, and the clan naturally treasures a large number of sealing classics.

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

Because since the Thousand Hands Pillar assigned the Tailed Beast to other villages, the importance of the sealing technique has greatly increased.

In order to better control the tailed beast in his hand, and at the same time to prevent others from using the sealing technique to deal with their own human pillar power, the three major ninja villages of Yunyin, Mistyin, and Iwain united with many small ninja villages to carry out a sneak attack on the country of vortex, and finally destroyed it.

It can be said that the magical operation of the big pillar to distribute the tailed beast has made his wife's maiden family miserable.

As for the seals......

Although most of the valuable texts were divided among the ninja villages besieging the country of Vortex.

But 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 that falls, and the ninja world is full.

However, when Natsuhiko began collecting these texts, many years had passed since the fall of the Vortex Country.

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

Whenever Xia Yan heard that someone had found a precious sealing technique cheat in the black market before, he was very envious, regretting that he was not born a few years earlier.

In addition to the normal furnishings of the study, there are three small desks in the corner, which are also full of various books, notes and rune papers.

This was specially purchased by Xia Yan for the three clones with short hands and short feet.

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

"Alright, now it's time to start reporting on the progress of your work today."
