Konoha: The seal art teacher of the ninja school

The morning of September 1st, Konoha 42nd year.

It has been raining non-stop since early morning.

In the white rain and fog, the fire shadow Yanyan on the rock wall in the distance seemed to be covered with a ray of gauze, looking hazy and faintly visible.

There are not many pedestrians on the street, but their faces are full of hope and vitality.

It has been two years since the Second Ninja World War ended. People have gradually hidden the pain caused by the war deep in their hearts and gathered their spirits to welcome the arrival of a new life.

"I haven't been back for a few years. It seems that the village has recovered well."

A young man wearing a black ninja uniform was walking leisurely on the street, holding a bunch of three-color meatballs in his hand and eating them as he walked.

He looked to be only fifteen or sixteen years old, with messy silver curly hair, delicate but slightly lazy features, and a forehead protector on his forehead that symbolized his identity as a Konoha ninja.

Although he didn't hold an umbrella, there was no sign of being wet by the rain on his body, which added a touch of mystery to him.

The boy's name is Natsuhiko Ubu. He was recently promoted to special jounin. Due to his mission, he needs to stay abroad for a long time and has not returned to Konoha for a long time.

When he returned to Konoha this time, he actually shouldered an important mission.

That is to serve as the sealing arts teacher for the new semester of the ninja school.

"I didn't expect it to go so smoothly. Not long after I submitted the application, the transfer paperwork came without even an interview."

Xia Yan was in a good mood, humming softly, and his steps seemed particularly brisk.

In fact, he had applied for this position several times before, but unfortunately the school rejected him every time because he was too young.

Xia Yan was not happy about this.

Children as young as five or six can go to war, so what’s the point of becoming a teacher at sixteen?

You must know that his ability to become a special jounin depends on his attainment in the sealing technique.

But this time he finally succeeded, and it seemed that the village finally recognized his strength.

Thinking of this, Xia Yan couldn't help but laugh at himself.

Perhaps in the eyes of many people, he, who became a special jounin at the age of sixteen, is Konoha's rising star.

But Xia Yan knew it himself.

Compared to those three-year-old genin, five-year-old jounin, those who achieved the Six Paths before the age of ten, and who also allowed Kaguya to take maternity leave, his achievements are nothing to mention.

Even Uzumaki Naruto, the protagonist of the original work, was only sixteen years old when he became a six-path powerhouse.

Sure enough, people cannot be generalized.

well!

Who made him a low-end time traveler with no plug-ins, no special bloodline, and mediocre talents?

To be honest, Natsuhiko's ability to become a special jounin is already considered extraordinary.

You must know that when he was in ninja school, he even considered whether to give up ninja and join the kitchen, drop out of school and become a ramen apprentice. That would at least make it to the end.

He was able to achieve his current strength only because of his good luck. After graduation, he was assigned to the sealing class.

Because there, Xia Yan got a valuable opportunity to learn the art of sealing.

The so-called sealing technique is a special ninjutsu that uses runes to limit the opponent's chakra, block the opponent's movements, and even reduce the dimensionality of things.

Although the sealing technique in the original work is not as cool as the ordinary ninjutsu illusion, it plays an important role every time it appears.

From the curse seal on Sasuke to the evil seal cast by Kakashi, from Orochimaru's Five Elements Seal to Jiraiya's Five Elements Interpretation Seal.

There are also the Yin seals of Tsunade, the various seals of the Jinchuuriki, and even the seal of Otsutsuki Kaguya by the Six Paths Sage brothers, all involving the use of sealing techniques.

Xia Yan's journey of learning the art of sealing began with a book called "Introduction to the Art of Sealing".

This book is a textbook written by the sealing master Uzumaki Mito himself when the Ninja School was first established.

It contains detailed annotations on various basic runes used in sealing techniques, making it very suitable for beginners to get started.

From the two most fundamental runes, Yin and Yang.

Then go to the five elements corresponding to the basic chakra attributes: fire, wind, water, earth, and thunder.

Then there are various functional runes: open, close, branch, loop, jump, select, add, subtract, multiply, divide, input, output, up, down, left, right, east, south, west, north,

Medium, hair, white...

Different schools of each rune have different writing methods, and various transformations must be made according to the specific use.

And this is the version that has been simplified and edited by Mito-sama.

It is not difficult to see that sealing technology is similar to mathematics.

Even if I'm forced to do something urgent, it still won't happen if it should be done.

However, when Xia Yan learned the sealing technique, he felt like a fish in water.

Having been a programmer in his previous life, he quickly discovered that these runes were very similar to something he was familiar with.

That is...computer programming language!

And it's a high-level language with a standard library.

In order to test his idea, Xia Yan tinkered with a small invention after learning the basic runes.

A rune scroll made according to programming ideas.

Its functionality is very simple.

When Natsuhiko inputs chakra, a line of text will appear in the blank box in the center of the scroll.

【hello world】

It seems to be greeting the new world that is coming.

Xia Yan's idea is correct!

These runes are not just tools used to perform sealing techniques, but a programming language for chakra.

This made Xia Yan couldn't help but recall the record in "Introduction to Sealing Art" about the inheritance of sealing art from the Immortal of Six Paths, combined with the plot of the original work he had seen in his previous life...

He suddenly felt like touching a switch, and a flash of lightning flashed in his mind!

Natsuhiko never understood before. Chakra was brought to the ninja world by Kaguya, and seals were invented by Indra. So what did the legendary Sage of Six Paths explain the truth of chakra to everyone?

Now he understands.

It's a sealing spell.

Perhaps when the Six Paths Sage explained the truth of chakra to the world, he was actually teaching everyone how to program chakra through runes.

Perhaps the so-called Ninja Sect is actually a programming training institution.

Then the Sage of Six Paths once wanted to connect everyone through chakra, maybe he was building the Internet!

So, the Immortal of Six Paths is actually his colleague?

Xia Yan felt that his fixed thinking about sealing techniques was suddenly broken, and countless sparks of inspiration burst out in his mind.

With his mind wide open, he soon came up with a bold idea.

Maybe he can use this chakra programming language to create a system of his own!

No system plug-ins?

Then he'll knock one for himself!

For a time, Xia Yan was filled with enthusiasm and felt that his life was full of hope again.

Unfortunately, the ideal is very full, but the reality is very skinny.

Creating a system based on chakra is ten times more difficult than Xia Yan imagined.

Although the rune language based on chakra and the computer language based on electronic components are similar, they have many differences in details and cannot be applied mechanically.

Moreover, the rune language has been passed down from the Six Paths Sage era to the present day, and after thousands of years, there are many deficiencies and errors.

Xia Yan is like self-study with a incomplete C language textbook full of errors. He has to slowly explore many places on his own.

In the days that followed, he was either performing various tasks or collecting information on sealing techniques in various parts of the Land of Fire, or he was studying at home, integrating the knowledge he had learned in two lifetimes.

Six years have passed now.

After several iterations, Xia Yan used the chakra conductive metal he bought with his savings to finally shrink the original small mountain-sized prototype into a fist-sized chakra metal ball.

He used this as a carrier and reluctantly built a simple system.

The biggest feature of this chakra-based system is that it can directly interact with humans and machines through chakra.

Skip the keyboard and mouse set.

It is similar to the intelligent brain or human brain chip that appears in science fiction movies.

However, Xia Yan did not dare to stuff the fist-sized metal ball into his head, but instead sealed it in his stomach.

In theory, he is still a computer jinchuriki.

Not long after Xia Yan completed this "Chakra Intelligent Brain", there were only a few programs in it, and it was still far from what he imagined.

But at this time he felt that he had reached a bottleneck.

If you want to continue to upgrade the system, you need to master more sealing runes and earn funds to purchase rare materials.

Returning to Konoha this time to become a sealing teacher is the first step for Xia Yan to solve these problems.

Yes, Xia Yan wanted to become a teacher not for teaching and educating people, but for the books in the school library.

When the ninja school was established, the major ninja clans donated many books at the call of the First Hokage, and they are still in the school library.

Although there are basically no good things, most of them are obscure ninjutsu scrolls from a backward era, or miscellaneous notes and travel notes written by predecessors.

For most people, it may be just tasteless, but for Xia Yan, it is an unexplored treasure mountain.

Because the runes have many similarities with the ancient writings of the ninja world, there is no telling which book can inspire Natsumi to restore the lost runes.

Not to mention that the library still contains ancient books on sealing techniques donated by Mito-sama on behalf of the Uzumaki clan, which are treasures that only a few teachers can read.

Therefore, even though Xia Yan knew that "teacher" was a high-risk profession in this world, he still decided to become an honorable teacher.

"I hope the books in the library will not disappoint me."

Xia Yan murmured, throwing the finished bamboo sticks into the trash can on the roadside, and walked towards the ninja school.

Today happens to be the start of the new semester at Ninja School.
