Konoha: The seal art teacher of the ninja school

Chapter 14 Teaching aids?

The time went back to ten minutes ago.

Xia Yan handed the paper to Jiu Xinnai, and seeing her start to answer the questions, he returned to his seat and took out the textbooks to prepare for tomorrow's class.

In the quiet office, only the rustling of pens could be heard for a while.

A few minutes later, the sound of rustling pens began intermittently.

Then, as time went by, the interval between the sound of writing became longer and longer.

After a while, the sound of writing was no longer heard.

Xia Yan looked up.

At this time, Kushina was leaning back on the chair, with her hands drooping, her eyes staring blankly at the ceiling, her whole body seemed to have lost its color, as if she had burned her life to ashes.

It seems to be the limit.

"Is it done?"

Xia Yan put down his textbook, got up and walked over.

"Wait a minute! I'm about to figure out how many chickens and how many rabbits there are."

Xia Yan's words frightened Jiu Xinnai, and hurriedly lay down on the test paper, as if afraid that Xia Yan would snatch the paper away.

It seems to be stuck on the problem of chicken and rabbit in the same cage.

Xia Yan was a little speechless: "That... This question requires you to design a rune formula to solve this problem. It's useless if you just calculate the answer."

"It seems to be the same..."

It was only then that Jiuxinna remembered that this paper was about the sealing technique, not mathematics!
After realizing this fact, she felt sad for a moment, hugged her head and shouted: "Then why did I just think about it for a long time!"

……

After struggling for a while, Kushina finally chose to give up.

After she handed the test paper to Xia Yan, she collapsed on the table like a deflated ball.

Xia Yan smiled slightly, and began to roughly flip through the entire test paper.

He found that he didn't need to look at the specific answer at all, he could see a lot of information from Kushina's handwriting.

It can be seen that as the difficulty of the topic increases, Kushina's handwriting has changed from confident and smooth at the beginning to hesitant strokes...

By the end, the handwriting had become crooked and illegible.

Xia Yan looked carefully for a long time before he saw the words between the words. There were two words written on the second half of the paper——no!
Now he probably understands Kushina's true level.

To put it simply, his basic skills are solid, and he has memorized all kinds of basic techniques fluently. Obviously, he has put in a lot of hard work.

It's a pity that in terms of application, she can only follow the scriptures, and she should rarely try to design spells by herself, so when she asks her to design a spell to solve the problem, she will be blinded.

For example, the essence of the problem of chickens and rabbits in the same cage is a linear equation in two variables, which is actually used in many sealing techniques.

If those problems are asked to Jiu Xinnai, she will definitely be able to solve them.

As a result, Xia Yan just put clothes on it, and Jiu Xinnai didn't recognize it anymore.

Hey, why does this metaphor sound familiar?

All in all, the test results were similar to what Xia Yan had guessed before.

It can be seen that Kushina has no enthusiasm for the sealing technique, but is forced to learn it because of his mission as a future Jinchuriki.

Xia Yan seemed to be able to see the picture of the little Kushina, under the supervision of Mito-sama, carrying various rune formulas with a sad face.

"Did I do poorly in the exam?" Kushina asked a little nervously.

Xia Yan stared at the paper for a long time, which made her a little guilty.

Only then did Xia Yan come back to his senses, and said with a smile: "You are already very good at your current age. You have a good grasp of basic knowledge, and some of the small traps I designed have not caught you at all."

Although I fell into a big trap when I first came to the office.

Jiu Xinnai felt relieved after hearing Xia Yan's praise, and touched her head in embarrassment, but she quickly realized again.

Aren't you Yu Sheng Xia Yan about the same age as me?
It's very good that I'm like this, so wouldn't you go to heaven?

Teacher Xia Yan, aren't you really praising yourself in circles?

and……

Jiu Xinnai was a little frustrated and said, "I don't know many of the following topics..."

"This is normal, because the following topics are no longer in the normal category of sealing techniques." Xia Yan explained, "It's my own style."

"I personally think that runes should not be limited to sealing techniques, but can be used to solve more problems, whether in combat or in life."

"So the application questions at the end of the test paper are all life problems that need to be solved by flexible use of runes."

"I see……"

Jiu Xinnai nodded half-understood, but what she was thinking about in her heart was what kind of bullshit life problem is the chicken and rabbit in the same cage.

Before counting how many chickens and how many rabbits there are, there should be a more important question: why should they be kept together?
Xia Yan naturally didn't know what was going on in Jiu Xinnai's mind, and thought she didn't quite understand it, so he simply suggested: "Just in time, I want to prepare the teaching aids for the next class. If you help make them, you should be able to understand me a little bit. meaning."

"Teaching aids?"

Jiu Xinnai's eyes glowed, and he regained his spirit immediately.

"Is it related to the projection technique you used in your first class?"

After she came to the school today, she heard everyone discussing the legendary first class, and she was already full of curiosity about the projection technique.

Not to mention her teaching assistant position, which was added temporarily because Xia Yan's courses were too popular.

Regarding Kushina's question, Xia Yan nodded and said:

"The use of these teaching aids does involve the principle of projection techniques, but although they are all used to stimulate everyone's interest, they are somewhat different from the focus of the images I show students in class."

As he spoke, he took out a storage card and put it on the table to unseal it.

As the white smoke exploded, a cardboard box full of small pieces of paper and two strangely shaped machines appeared.

Xia Yan first took out a large stack of papers from the box and handed it to Jiu Xinnai.

Kushina took a look and found that it was somewhat similar to the storage card Xia Yan used before.

However, Xia Yan's previous card was made of very good material, and it was quite valuable at first glance.

And these cards are made of two pieces of paper glued together, one side is ordinary hard cardboard, and the other side is a kind of yellowed paper, the paper quality is very poor, reminding her of similar things.

"This is... the talisman paper used to practice drawing runes?" Kushina hesitated.

"That's right." Xia Yan nodded, not surprised that Kushina could guess it.

The paper used to make talismans and scrolls requires a lot of special materials in order to be able to transmit and carry chakra.

If you want to use talismans and scrolls to perform more powerful spells, you need to use more precious materials to make them, and the price will naturally be higher.

A rookie who has just started to learn the sealing technique, even if there is a mine at home, it is impossible to use ordinary talisman paper to practice every time.

However, ordinary paper cannot test whether the chakra is instilled in place when constructing the rune formula.

So the predecessors invented a kind of talisman paper for practice.

The main materials of this kind of talisman paper are those inferior materials that can transmit chakra, but cannot carry too much chakra.

Its characteristic is that it can draw rune formulas, but it cannot be used in practice.

Because too much chakra before the operation is formed will destroy the entire rune, resulting in the failure of the operation.

Although there is no actual combat use, it is no problem to practice drawing runes. Of course, the most important thing is that it is cheap.

Xia Yan held a card and explained:

"This side is a talisman paper made with a special rush grass from Ijumura, the country of grass, as the main material."

"Compared to ordinary talisman paper for practice, this Yijuan papyrus is stronger and more durable, so I also bought a lot, and it just happened to be used this time."

Kushina also curiously picked up a card and checked it, and found that there was something printed on the side of the talisman paper.

It can be seen that in the box that occupies most of the paper, a basic rune formula is drawn, but it is not complete, and one or two key runes are missing.

Reminiscent of the questions in the test paper just now, Kushina easily thought that this was also a kind of fill-in-the-blank question.

Perhaps some function can be triggered by completing the rune.

Kushina couldn't help thinking.

And in the rectangular box at the bottom of the paper, there are some normal texts printed on it.

But Kushina became more and more confused the more he watched.

Because she knew every word above, but couldn't read them together.

I saw that it said:

[The first generation of Naruto Senjubashima]

[Cost 7, Attack Power 7, HP 10]

[Birth of the Tree Boundary: When entering the field, change the field to "forest", and deal 1 damage to all units on the opponent's field at the beginning of the round]
