After a short rest, Xia Yan began the most important work of the day.

That's preparing for tomorrow's first class.

Xia Yan sat at his desk, picked up a textbook on the table and flipped through it.

When he went to school, it was close to the Second Ninja World War, and the ninja school activated the wartime mechanism.

Many classes have been cancelled, including sealing.

Xia Yan's sealing technique was only learned after he was assigned to the sealing art class.

So he really hadn't taken the sealing class seriously, and he didn't know much about the content of the sealing class at the ninja school.

It seems that the current sealing art class was re-established only two years ago.

Xia Yan looked through these textbooks and found that it was even simpler than he imagined.

And there are several duplicates of these books, in fact, there is only one textbook and two reference books, plus three teaching notes from previous teachers.

In fact, the entire sealing technique course only needs students to understand a textbook that is not too thick.

This textbook is essentially based on the "Introduction to Sealing" written by Mito-sama, but a lot of advanced knowledge has been deleted.

The goal of the whole book is to enable students to draw a series of basic sealing techniques such as a series of lantern arrays in the same way after they finish learning, as well as to be able to detect and crack basic sealing traps.

And to this extent, Xia Yan was able to do it after studying in the sealing class for half a year.

But that's right.

After all, this course is only an elective course, with only three classes a week, plus the students have other study tasks, and it is not bad to be able to learn a series of lamp arrays in the end.

At the end of the day, this course is just a screening to find out what kids really have the ability to seal.

And after graduation, these children will be assigned to the sealing class, and only then will they begin to learn the real sealing technique.

It can also be seen from the teaching diary that the previous teachers obviously understood this and invariably adopted the cramming method.

Students are only asked to memorize the sealing runes by rote, without explaining the role of each rune in detail.

I only know what it is, but I don't know why it is.

When Xia Yan first started reading his notes, he was still a little scoffed at what they were doing.

But after considering the class length and the teaching tasks to be completed each semester, he actually found that Xiao Gui Cao followed, and continuing to let students memorize by rote was actually the most cost-effective way.

However, Natsuhiko quickly rejected this path.

It's so unchallenging.

Moreover, he came back to be a sealing teacher this time, and in addition to coveting the library's collection, he also had the task of training some assistants to share his own research topics.

After all, a person's energy is limited, and even the Great Snake Pill has a pharmacist as an assistant.

And if you let students memorize by rote, you will not be able to discover the talents he needs.

After all, it is absolutely impossible to raise people's intellectual level by instilling a large amount of superficial knowledge and memorizing a large number of textbooks without making mistakes.

What really helps students succeed is judgment, experience, a pioneering spirit and personality.

Another reason is that Natsuhiko doesn't know exactly when the Third Ninja War will start to break out, and he is worried that the sealing course will be canceled again as before.

So he had already decided to make new ideas and make achievements, with the goal of surviving the elective battle royale in the future.

"If you don't have to make the students memorize, then you have to explain the basic runes one by one."

Xia Yan originally wanted to use the memo program to record his thoughts, but after thinking about it, he still took out a new notebook and wrote it with a pen.

"Considering that in order to motivate the students, there are also some interesting practical sessions to be added, why should they be allowed to write a diary in runes?"

"No, maybe we can focus on a simple technique, so that everyone can master this technique at the same time after learning the required runes, so that at least there is some hope." Xia Yan muttered.

"The most basic series of light arrays is still a bit complicated for students, and it is not something that can be learned in a short time, and it probably shouldn't be limited to sealing techniques."

"If you add this part of the learning content, the class time may not be enough, and some learning tasks have to be left for students to complete after class, which will increase everyone's burden, and other teachers may also have opinions."

Xia Yan scratched his head and crossed out several written thoughts.

"The key is to focus on which technique, not only does not add too much burden to everyone, but also has to be practical, and it also contains most of the basic runes."

Xia Yan opened the system interface and began to look through the various techniques recorded in the casting assistance program.

The art of displays.

Umbrella Technique.

The art of BGM.

The art of the camera.

The art of the flashlight.

……

"If you don't want to increase everyone's burden, it's really not too fancy, you have to start with the three-body technique that you must learn in school......"

In the end, Xia Yan's gaze stayed on the one at the bottom of the list.

Projection is also known as the projector technique by Xia Yan.

This technique is actually a combination of the principles of the doppelganger technique and the transformation technique, and the effect is to be able to turn your own doppelganger into the appearance of other things and project it near yourself.

The effect is similar to the holographic projection of Xia Yan's previous life.

This technique was created by Natsuhiko through the analysis and study of the three-body technique after he began to study the ninjutsu talisman culture.

From here, you can see a little bit of the horror of chakra.

In his previous life, he had studied the holographic projection that had not been popularized for decades, and in this world, Xia Yan, a trainee who had been practicing the sealing technique for a year and a half, made the holographic projection out.

Don't look at this technique, it doesn't seem to be lethal.

In fact, for a long time in Natsuhiko's sealing class ninja career, this technique was his killer weapon, and it had countless wonderful uses.

And because the difficulty of this technique is not too high, in addition to using the rune version, Xia Yan even reversed the reverse and developed the seal version.

And with the help of the Casting Assist Program, he can even create very complex large-scale illusions.

The more Xia Yan looked at this technique, the more he felt that it was appropriate.

As students practice the runic forms used to construct this technique, they will also gain a deeper understanding of the transformation technique and the clone technique, which will help them master these techniques.

It's not easy for me to be a sealing teacher, and I've done all the work of a ninjutsu teacher.

Xia Yan chuckled.

Although teaching this technique to his students made Xia Yan a little painful, he finally gritted his teeth and made up his mind.

After all, in a few years, the Third Ninja World War will break out, or many students will be able to survive by learning such a technique.

After making up his mind to make projection the core of his teaching, Xia Yan suddenly had a wellspring of inspiration, and many ideas that could not be realized back then because of running around seemed to have a place to use again.

The pen in Xia Yan's hand danced rapidly, recording unbelievable thoughts in his notes.

It wasn't until the sun went down and the light in the office was so dim that he couldn't see anything that Xia Yan came to his senses, looking at the dense text and stick figures on the notebook, and couldn't help but smile.

Although there is still a lot to be discussed, it is enough to cope with tomorrow's lesson.

Xia Yan, who closed the notebook and was about to leave, suddenly had a thought in his head.

Maybe in a few months, a new sealing teacher will come to this office.

After seeing this notebook, I may sigh at the whimsy of my previous teacher, but unfortunately I died too early.

After shaking his head and throwing this image out of his mind, Xia Yan felt that this dimly lit office looked a little eerie.

It's not too early, but it's still slippery.

Xia Yan quickly cleaned up the desktop and left the office quickly.

Xia Yan, who was walking towards the school gate, ran into a corner of Umino, who was also busy getting off work, and was forcibly dragged by him to his house for dinner.

At the home in the corner of Umino, Natsuhiko met the teacher's wife, Umino Hairi, and the two newborn children, Iruka.

It can be seen that this kid is very talented in water escape, and as soon as he saw Xia Yan, he tried to sneak attack him, a fifteen-year-old man, with a water escape water gun.

However, Xia Yan still easily dodged, but the corner of the sea field behind him was scolded.

After eating at Umino's house and chatting with Mr. and Mrs. Umino for a long time about his experiences over the years, Natsuhiko finally got rid of the enthusiastic two and returned to his home.

After some tired Xia Yan washed up a little, he went straight to bed and recuperated to meet the official start of his teacher life tomorrow.
