After the boys had changed into their training clothes for a while, the two girls squirmed out of the cubicle.

In a trance, Xia Yan seemed to see two Kunkun coming over.

As soon as they came out, Asma, who was wearing a pink bodysuit, stepped forward and shared her experience with Red.

"Red, this training uniform is so powerful, it's the same as if you didn't wear it, do you feel this way?"

The red face turned black all at once.

Xia Yan on the side was also a little unbearable.

Because he was a little worried, Ape Fei might not be able to be born in the future.

In order to prevent Asma from saying anything shocking again, he hurriedly clapped his hands and said:

"Now that we're all ready, let's head to the training ground."

"Eh——!!"

Sunset looked at Xia Yan with a frightened face, "Wait! Teacher, aren't we testing here? ”

It's good to be seen by everyone in training clothes, but if other students see her like this, how will she see people in the future?

"The space here is too small for you to use to achieve the effect of the test."

Xia Yan looked like a matter of course.

At this time, Lin behind Obito saw red also couldn't cry or laugh, and hurriedly volunteered:

"Don't worry, I've been training with Arcate for many days, and I know how to walk without being discovered, so you can follow me."

Nohara Rin and Sunset Red glanced at each other, and finally gritted their teeth and reluctantly accepted Obito's proposal.

So everyone left the office again, and under the leadership of Obito, like a guerrilla, sneaked to the training ground behind the teaching building.

There, there are already two figures waiting.

It was Jiu Sinai and Maite Dai.

It's just that unlike usual, Maite Dai is also wearing a yellow leotard now.

Because he came here today for the small task that Xia Yan had told him before.

That is, to demonstrate the function of the training suit to the students.

So although he still felt that the yellow tights were heretical, he gritted his teeth and put them on out of professionalism.

It's just Mr. Xia Yan's task.

But this also caused the scene to be very awkward when the Maite father and son, who were both wearing yellow tights, met......

It's comparable to a father and son meeting in the custom street, and neither of them is a guest yet.

……

Regardless of the Matt father and son who went to the side to talk.

Xia Yan first clapped his hands to attract the attention of other people who were eating melons and watching the play.

"Time is limited, so let's start testing the training suits as soon as possible."

"First of all, let's introduce a little bit about the principle and use of this training suit."

Saying that, Xia Yan looked at Obito.

"Obito, I introduced you before, how much do you remember?"

Originally, he was still stealing a glance at Nohara Lin's belt, but when he heard Mr. Xia Yan call his name, he suddenly shuddered.

However, he thought about it and found again: Hey, he seems to know how to answer this question?

Because the teacher said that this tights were made by imitating the principle of writing wheels, he was impressed.

So Obito became arrogant again, and said to the other students in a somewhat mocking manner:

"I tell you! This outfit allows one person to perfectly copy another person's movements! ”

"I used this dress to learn all of Akai's Konoha fluid technique."

Rin, Hong, and Ebisu were all amazed when they heard this, but they didn't expect that the sealing technique would still have this kind of use.

Only Asma was amazed when she saw Hong, and she was not to be outdone:

"Hmph, what's so great about the Konoha Fluid Technique, let me come next time and give you a copy of the Ape Flying Fluid Technique of our Ape Flying Clan."

“……”

When Xia Yan heard this, there were a few more black lines on his forehead.

Don't sell your own school so easily for the sake of picking up girls!

He shook his head helplessly and pulled the topic back:

"Obito, what about the principle?"

"Forehead......" Obito scratched his head, "I remember that it seems to have used a perception circle?" ”

"That's right, but we have to add the Resonance Circle."

Xia Yan added, then looked at the other students.

"As Obito and I said just now, these training uniforms have a perception circle and a resonance circle drawn on them."

"Therefore, the chakra flow and body movements in one party's body can be recorded, and then reproduced on the other party, so as to achieve the effect of a physical copy."

"But we're not testing this today, so we won't go into depth."

"The feature we're going to test today actually needs the help of a small prop."

Seeing that everyone was looking forward to it, Xia Yan didn't sell it, and took out a storage card to unseal it.

Boom.

After the white smoke passed, Xia Yan had a small pile of scrolls in his hand.

Then he handed out the scrolls one by one.

"Daddy!"

"Akai!"

"Daddy!"

"Akai!"

At this time, Matt's father and son over there also completed the hot-blooded routine process of arguing, domestic violence, and hugging and crying.

The two didn't know what consensus they had reached, so they walked over with teary eyes and each received a scroll.

Xia Yan saw that Jiu Sinai was not very gregarious standing aside with his hands behind his back, so he said:

"Jiu Sinai, didn't I give you a training uniform before, it's still red, didn't you bring it?"

Who knew that Jiu Sinai said to him expressionlessly:

"Even if I, Kushina, die, and jump from Hokage Yanyan, I won't wear that kind of thing!"

"And!" Kushina gritted her teeth and added, "Don't wrap that thing as a gift in the future." ”

God knows how she felt when she came home that day and happily opened the gift and found out that it was a tights!

Grandma Mito was on the verge of laughing.

Xia Yan, who didn't know that he almost caused the Nine-Tails Rebellion in advance, saw that Jiu Xinnai's hair began to float, and he didn't dare to say more, and fell back with a smile on his face.

At this point, the others had already opened the scroll and found that it was blank, so they were flipping through it.

Xia Yan coughed lightly a few times to attract everyone's attention, and then reminded:

"You can inject the chakra into the scroll and see what happens."

So the students and Maite Dai were curious to do what Xia Yan said.

With the infusion of chakra, they were surprised to find that various numbers and symbols formed by ink began to appear on the scrolls.

But what caught their attention the most was a picture that took up most of the entire canvas.

This picture is not unfamiliar to everyone, as they will see it on the first day when they learn to refine chakra.

Chakra meridian diagram.

However, the chakra meridian diagram on this scroll is much more detailed than that in the textbook.

Xia Yan began to explain again:

"Chakra is a mixture of the physical energy taken from the 130 trillion cells of the human body, one by one, and the spiritual energy that has been tempered through arduous cultivation and accumulated experience."

"Then, just as blood flows through blood vessels, the refined chakra can also reach all corners of the body through meridians throughout the body, which is the so-called meridian system."

"And there are 361 chakra acupoints in the meridians, and if you compare chakra to water, then chakra acupoints are water outlets, because chakra can be released from them."

"Everyone learned these things when they first went to school, so you should remember them."

Everyone nodded their heads in remembrance.

Only a certain Kenji doesn't feel as confident as everyone else.

Xia Yan didn't see it when he saw this: "Since everyone remembers, I won't talk about it at length." ”

"Then you can try to mobilize the chakra in your body and see how the painting in your hand changes."

Everyone did what Xia Yan said, and soon made amazing discoveries.

They found that as they took control of the chakra, the blue ink on the meridian diagram that symbolized the chakra would change accordingly.

Gather the chakra on the left hand, and the blue ink on the figure will also gather on the left hand of the figure.

Vice versa.

Even when they extract chakras from the cells, there is more blue ink on the corresponding part, and various parameters are displayed next to it.

"It's amazing!"

Everyone had a lot of fun with the scrolls and tried all kinds of things.

Even the boys began to compete with this meridian diagram, frantically mobilizing their chakra, trying to make it unable to react.

But it's like a cat battling wits with a mirror,

The result, of course, ended in their fiasco.

Xia Yan didn't go on right away, and waited patiently for a while.

Seeing that everyone was playing about the same, he spoke:

"The principle of this scroll is very similar to the action copy function just mentioned, but this time it is not a copy action, but the various information of the meridian system in your body is directly displayed on the scroll."

"In this way, people can more intuitively judge the flow of chakra in their body, rather than relying only on feelings."

Asma, who usually plays a lot of forbearance game consoles in the tavern, is not too surprised by this dynamic meridian map.

He had an idea, raised his hand and asked:

"Teacher, if you use projection, you should be able to generate a more intuitive image."

The other students also felt that it made sense when they heard it, and they couldn't help but look at Xia Yan.

Xia Yan also nodded and praised: "Very good, everyone should learn from Asma, know how to live and learn, and draw inferences from others." ”

Just when Asma was touching her head and smirking, she heard Teacher Xia Yan say again:

"But you're ignoring the issues of cost and portability."

"The teaching aids we are testing now may be popularized in ninja schools in the future, so we can only save costs as much as possible."

"And the projection machines you are talking about, which are either portable but costly like duel discs, or medium-cost but difficult to carry at any time like thrilling game consoles, are not suitable for popularization."

"At most, put a few desktop machines in the school in the future, and use them when students need more detailed meridian maps."

Everyone nodded their heads again and again.

Xia Yan said again:

"I happened to have made one of the portable machines, so I'll show you how to do it."

As he spoke, Natsuhiko took out a small machine and threw it to Asma.

"Here, put this combat probe on."
