Konoha: The seal art teacher of the ninja school

Monday afternoon, Ninja School Sealing Arts Office.

Since Kushina went to the classroom to supervise everyone's practice of drawing runes, Natsuhiko was the only one left in the office.

At this time, he was sitting at his desk, humming a tune while repairing the combat power detector that was blown up by Matt Dai.

Looks like he's in a good mood.

After all, he had gained a lot in the past two days and got a lot of useful things from the root ninja.

The first is naturally the illusion he calls Bietianzui.

After unremitting efforts, No. 2 finally roughly analyzed this technique.

Unlike ordinary illusions that cause the opponent to hallucinate, this technique directly affects emotions through chakra, which greatly inspired Xia Yan.

After all, chakra is a one-to-one mixture of mental energy and physical energy.

There is naturally a very close connection between emotions and chakra properties.

For example, Senju Tobirama has researched that when people of the Uchiha clan lose important things, strong hatred will cause special chakra to emerge in the brain, which will act on the optic nerve and cause changes in the eyes.

And this is the so-called eye that reflects the soul - the Sharingan.

At the same time, when this kind of chakra appears, it will in turn affect the spirit, causing a person's personality to change drastically and fall into evil ways.

As for why the Nidaime is so aware of the physiological principles of the Sharingan, we will not discuss this topic for the time being.

So when the root ninja broke into his house in the middle of the night and was captured by the defensive barrier.

Xia Yan had the idea of ​​doing two things without doing anything, and decided to test his ideas on him.

So he threw the ninja into a box reinforced with sealing techniques and let him play cards in fear of being overwhelmed by natto.

Then I explored the relationship between emotions and the nature of chakra by studying the chakra extracted from the ninja game machine.

Sure enough, under the pressure of Natto Hell, the chakra of the ninja in the root changed drastically.

If you were the protagonist, if you should activate the Sharingan, activate the Sharingan, and if you should explode the Nine-Tails, activate the Nine-Tails.

It's a pity that this guy didn't have the halo of the protagonist, so he was in extreme fear for most of the day until he ran out of chakra.

However, Xia Yan also got a lot of interesting data, and at the same time, he also got rid of a lot of natto that No. 3 secretly bought at home.

It's really a win-win situation.

Although Natsuhiko has not thought about the use of this research, this set of equipment can be modified and sold to the Uchiha clan at a high price in the future.

Let them open their eyes too.

Anyway, this machine was pickled with natto, and Xia Yan didn't dare to take it out of the storage scroll.

Finally, Xia Yan got an unexpected surprise from this root ninja.

That was the discovery of a rune technique in the opponent's chakra that he had never seen before.

Based on his memory of the original work, Xia Yan quickly determined that this thing should be the infamous curse seal technique.

It seems that in addition to the curse seal marks on the body surface, there are also curse seal techniques hidden in the chakra in the body.

As the most secretive and evil form of sealing, curse seals have always been passed down orally and are rarely recorded and spread with pen and paper, so Xia Yan has rarely dabbled in this aspect of knowledge.

Now that he encountered it, he would naturally not let go of the opportunity to study it.

Xia Yan discovered through observation that it was different from many sealing techniques that simply absorbed the opponent's chakra.

The curse seal formula is directly rooted in the soul. When the host refines chakra, it will incorporate its own information to form a new curse seal formula to achieve the purpose of self-replication.

This reminded him of a familiar thing - viruses.

It also enters from the outside world, and it also parasitizes in the human body, using resources to replicate itself.

It can lurk in the human body without making people aware of it, or it can be expressed and cause various adverse reactions or even death in the human body.

So the curse seal is essentially a chakra virus?

It seems quite reasonable.

Since rune is a programming language for chakra, it is not surprising that curse seal is a chakra virus.

So, is this chakra virus a computer virus or a biological virus?

Xia Yan soon realized that the curse seal technique would play a very important role in his subsequent research, and even some plans would be adjusted accordingly.

It seems that there are more things to study.

Xia Yan smiled helplessly, this is really a luxurious trouble.

…

When school was over, Xia Yan had just repaired the combat effectiveness detector when he heard the footsteps and voices of several people coming from outside the door.

It sounded like they were arguing about something.

Then the office door was opened, and six members of the research team walked in one after another.

I saw Hong fuming, Lin, Asuma and Ebisu looking helpless, and Kai looking full of energy as usual.

Only Obito was dejected and finally walked into the office.

Well, it seems our local brother has gotten into trouble again.

However, Xia Yan didn't take it seriously. After placing the combat power detector, he said:

"I have put the training clothes and the meridian scroll on the table over there. You can put on your clothes first."

However, as soon as he finished speaking, only Akai happily walked over and picked up the training clothes, while the others looked embarrassed.

"Teacher, teacher!"

Hong quickly ran to Xia Yan, raised his head, and said with a cute look on his face:

"Teacher, can we move to another place to do the activities?"

"Oh? Isn't the training ground behind the teaching building good?" Xia Yan said casually.

Hong gets angry when talking about this: "It's all because of that idiot Obito, who told others about our activities there! Everyone said they wanted to go and see it after school!"

When Obito heard this, he shrank his neck and felt a little embarrassed.

He now also deeply realizes his mistake.

After all, doesn’t this mean that Lin’s tight-fitting outfit will also be exposed?

Hong was dying when she thought about being seen by everyone wearing tight clothes.

So she begged with all her face: "So can we change places? Is the teacher okay?"

Everyone also looked at Xia Yan expectantly.

Except for Akai, who said he gets more excited when people look at him.

Xia Yan touched his chin and pondered, brewing a tense atmosphere.

Then he said slowly:

"A person's value lies in his talent, not in his clothes."

"Even if wearing this training uniform will attract everyone's ridicule, as long as it can improve our strength, it doesn't matter."

"One day, ten days, they might still be able to laugh."

"But what about one hundred days or two hundred days later? At that time, I can guarantee that they will never laugh again."

"Is it because we have become stronger?" Asuma asked expectantly.

"No, because this training uniform will be popular in schools by then."

Everyone was immediately stunned!

All right.

That would really make everyone laugh.

But we can’t laugh either!

Seeing that everyone was speechless, Xia Yan could only clapped his hands and said:

"Okay, okay, let's do that. I will also wear training clothes this time, so you guys finally have no objections."

Everyone was shocked when they heard this and looked at each other.

They always thought that the shape of this training uniform was not only for functional reasons, but also had a bit of bad taste from Teacher Xia Yan.

But now Teacher Xia Yan actually takes the initiative to wear this training uniform.

Did they blame the teacher wrongly?

So everyone except Akai felt ashamed and sympathetic.

I feel ashamed for wrongly blaming a good person, and I also sympathize with the teacher's poor aesthetics, which is almost the same as that of Matt and his son.

Since Teacher Xia Yan was taking the lead, everyone had nothing to say and had no choice but to pick up a training uniform each.

Hong and Lin went to the cubicle as usual, and the boys also started to change their clothes.

But after everyone got dressed, they found that Teacher Xia Yan was still standing still, so Asuma was a little curious and said:

"Teacher, don't you also need to change into training clothes?"

Xia Yan smiled:

"Don't worry, because I'm already wearing it."

After that, he opened the buttons of his white shirt with both hands, revealing a black tights underneath.

There is also a white bat pattern on the chest...
