Konoha: The seal art teacher of the ninja school

In the courtyard of Senju Mansion.

In order to see the interesting sealing technique teaching tools mentioned by Kushina, Mito stood up and walked towards the stone table.

Kushina breathed a sigh of relief when she saw this, followed her, opened the box and showed it to Grandma Mito.

In addition to stacks of cards, there were two strange machines in the box.

"Grandma, do you recognize this thing?"

Kushina raised her head and asked with a proud look on her face.

People who don't know think she invented these two machines.

Mito rolled his eyes at Kushina, then reached out and picked up one of the machines to check it out.

The slender green fingers gently stroked the somewhat rough wooden shell of the machine, from the disc-shaped core to the half-moon-shaped plate extending from the disc, even the slightly concave square card slot on it...

At the same time, strands of chakra thin threads quietly seeped out from her fingertips and penetrated into the machine's interior through tiny gaps in the shell, exploring its secrets.

Soon, Mito's two slender eyebrows were slightly raised, and it was obvious that he had gained something.

By probing with thin chakra threads, she first determined what materials were used inside the machine.

But there is nothing noteworthy, they are all ordinary chakra conductive materials.

Even the main material is produced by their Senju Clan, a special kind of oak with good chakra conductivity.

What these materials have in common is that they are cheap, durable and can be used repeatedly.

However, since it cannot withstand excessive chakra, the upper limit is not high, so the price is relatively cheap.

Therefore, it is generally used in making simple or temporary barrier arrays.

Of course, the low price is compared to other chakra transmission materials, but it is still valuable to ordinary ninjas.

So these materials are not yet worthy of Mito's attention.

What really surprised Mito was that these ordinary materials were densely engraved with various tiny runic techniques.

The large number of runes frightened Mito, who was well-informed, and he felt that the machine in his hand was a bit hot to the touch.

Is this thing really just a teaching tool, not some world-destroying ancient weapon?

You must know that when she assisted her brother-in-law to build the Thunder God Sword, she did not use so many runes.

And although they are all the simplest and most basic rune spells, due to their huge number and complex arrangement, the spell circuits formed have become extremely difficult, which makes her, as a master of sealing skills, confused for a while.

I can't even fully understand it.

However, Mito quickly judged that this was not a deliberate attempt to carve out so many runes for the sake of encryption or pretending to be sophisticated.

Because she felt the beauty of order in the arrangement of these runes that she had never seen before.

This is the design idea of ​​which ancient sealing school?

Mito couldn't help but have such an idea.

After all, the way of using this kind of rune is completely different from the mainstream sealing techniques she has learned over the years.

The sealing technique that is popular today is a simplified route that combines runes and seals, and lowers the threshold for using sealing techniques by converting a large number of runes into seals.

This is why many sealing techniques are now performed using seals.

If it weren't for the irreducible rune spells that need to be unfolded and released at the end of the spell, many sealing techniques would look no different from ordinary seal ninjutsu.

This is the evolutionary direction chosen by the sealing technique in order to adapt to the fighting style of ninjas and continue.

The design idea of ​​the rune spells on this machine goes in the opposite direction, taking the retro route of expressing everything in rune spells.

And it seems that they have gone further on this path than their predecessors...

"It turns out that road is not a dead end. It's interesting..."

Mito murmured unconsciously.

She had forgotten how long it had been since she felt that sealing was "interesting".

Because after years of continuous learning, the sealing technique has become an instinctive part of her body and integrated with her.

Even if you learn new knowledge, you will find that it is already included in your own knowledge framework, and naturally it will not cause any emotional fluctuations.

However, the runes on this machine actually caused her calm mind to throb again.

It feels like I have returned to the wonderful time when I first started learning the art of sealing and made new discoveries every day.

"Grandma Mito, Grandma Mito..."

Kushina, who heard Mito muttering to herself, called out a few times tentatively.

It's a pity that Mito didn't pay attention to her.

At this time, she was immersed in the pleasure of constantly analyzing the runes and spells on this machine and constantly gaining new knowledge.

Mito, who thought she had mastered the sealing technique, discovered that there was a whole new world on the other side of her research direction!

This feeling simply cannot be described in words.

To use an analogy from Xia Yan's previous life, it would be like Pokemon Gold and Silver opening up the Johto region. When I thought that there was not much content in this game, I discovered that there was an entire map of the Kanto region and eight gyms.

Waiting to explore by yourself...

With his profound knowledge of sealing techniques, Mito quickly discovered many clues inside the machine.

However, her expression gradually became more subtle as she analyzed the runes.

Because she discovered that most of the runes and spells engraved on the surface of the machine were just to achieve a simple function that was familiar to her: chakra diversion.

The so-called chakra diversion is to use rune techniques to divide a stream of chakra into several lines on the material, thereby reducing the material's requirements for chakra carrying capacity.

Because this method can greatly reduce the demand for materials, it is widely used and is not a strange design.

But the chakra diversion circuit on this machine refreshed Mito's understanding of the concept of chakra diversion.

She has never seen so many lines, and at the same time, the control on each line is meticulous, and the design is so complicated that it seems to squeeze out every ounce of performance of these materials before giving up.

What surprised Mito even more was that the purpose of the chakra diversion design on the machine was not to use it to perform more powerful techniques, but to reduce the wear and tear on materials when chakra flows and extend the life of the machine.

In addition, the materials used in this machine are cheap and durable...

Mito couldn't help but think:

Could it be that the designer of this machine intended to pass this thing down from generation to generation as a family heirloom?

Otherwise, there would be no such frantic efforts to improve its durability.

Even if the major ninja clans prepare to pass down clan boundaries from generation to generation, they have not yet reached this level!

After all, the more runes and spells there are, the greater the chance of problems occurring, and the gains outweigh the losses.

Mito rubbed his swollen temples, feeling a little confused.

Of course she couldn't understand.

Because all this is attributed to Xia Yan's five thousand years of traditional virtue inherited from the Chinese people - poverty!

Poverty sometimes limits people's imagination.

But poverty sometimes also makes people exert strong subjective initiative.

Squeezing out all the properties of the material and designing complicated chakra shunt circuits to extend the life of the machine are just basic operations done by Xia Yan, who is used to being poor, to save money.

And this is naturally unimaginable for the princess of the Uzumaki clan who has been pampered since she was a child, writing talismans and throwing them away.

Just like the big shot above, he always understands that feet are just for decoration.

But Mito didn't hesitate for too long.

She decided to ignore this part of the design for the time being and explore deeper into the machine.

However, her exploration soon encountered obstacles.

Because she discovered that the key components deep inside the machine were equipped with shielding circles, making it impossible to spy on the secrets through chakra means.

Mito was stunned for a moment, then shook his head and smiled bitterly.

In the excitement, I forgot about the anti-theft design that is found in almost all rune products.

From this point of view, violent disassembly and cracking methods should not be effective.

Mito, whose exploration was blocked, finally came to her senses and saw Kushina who was bored aside and did not dare to disturb her thinking.

She thought for a while and asked the question she wanted to know most now.

"Is this done by the kid named Xia Yan?"

Kushina was startled by her sudden words, and finally recovered.

After thinking about grandma's question just now, Kushina scratched her head and replied:

"Um...I didn't ask, but it should be."

Mito, who didn't get a definite answer, rolled his eyes at Kushina angrily.

"Look at you, you don't understand such an important thing, you only know how to play!"

You really got it right!

Kushina couldn't refute, so she had to stick out her tongue, trying to be cute and pass the test.

Snapped!

Mito was not used to Kushina, so he gave her a blow with his fingers. He looked at Kushina holding her forehead with tears in her eyes. After laughing, she couldn't help but sigh.

Thinking that the person who built this kind of machine was probably a child about the same age as Kushina, Mito finally felt that his own era had passed.
