Magicraft Meister Part 3

Just as Jin had expected, Hanna was in his laboratory.

"Hanna, there you are!"

When he called out to her, she looked up from the document she was examining.

"Oh, honey," she said.

"Jin, what's wrong?"

And there was Erza with her. She was helping him with something. On the table, there were some papers with the formula for the Magi Formula written on them.

Jin told them about his visit.

"No, I heard from the old man that you have completed a communication wave that can pass through the . ......"

"Oh, yes, I did, in a manner of speaking.

"Was it easy?"

When I first asked him about it, he said that it was not even in the conceptual stage yet.

* * * * * * * * * * *

A magic barrier is, in essence, a boundary that prevents the transmission of free magic element (ether).

Therefore, physical phenomena cannot be prevented.

Thus, flames generated by fire magic and water bullets generated by water magic are physical phenomena and cannot be prevented.

and can be prevented because they cause the effect on the object.

However, the most troublesome thing for Jin and others is that the magic barrier does not allow the communication by magic ......, i.e., free magic element (ether).

Therefore, once the magic barrier is put up, communication becomes impossible.

* * * * * * * * *

But Hannah shakes her head.

"No, it's not easy. ......"

"So?"

"Yeah, I said <>. I've created an alternative means of ...... communication."

You mean an alternative method of communication.

That's what I meant. Let's see. ......"

Hannah's explanation made perfect sense to me.

"It's communication by radio waves, honey."

"So that's what you mean ......."

Radio waves...... electromagnetic waves are a physical phenomenon and cannot be protected by a magic barrier. Also, depending on the wavelength, they can pass through physical barriers (solid barriers) that allow light to pass through.

"That's why I annotated and didn't report it to Oni-chan."

"I didn't think so."

Still, there is a big difference between being able to communicate and not being able to communicate even if there is a magic barrier in between.

"With the help of Erza-chan, I made a prototype of a magic tool for communication.

Hannah showed me a bracelet-shaped magical tool.

Like a wristwatch, the main part of the bracelet is attached to one part of the bracelet. It seems to be a speaker and a microphone.

"But you know, the radio waves ...... I used this time are of a wavelength equivalent to , but this time they are blocked by objects."

"Oh, I see."

The magic waves, which are free-magic elemental (ether) waves, can penetrate most matter, but radio waves can't.

"Ironic, isn't it? Radio waves that penetrate a magic barrier are now blocked by matter.

"Yeah, well..."

That's why I didn't tell you.

I understand.

"I'd like to be able to use the sub-free elemental ether wave if possible."

Sub-sub free-magic element (ether) waves are considered to be waves with even shorter wavelengths than free-magic element (ether) waves, and can even penetrate planets and stars.

It was thought that many more years would be needed to master them.

"Still, it's great to be able to communicate with people outside and inside the magic barrier more easily than before. Thank you, Hannah.

"Hehehe, I'm not satisfied yet, but I'm happy if I can be of help to you."

Hannah smiled happily.

Immediately Jin asked, "So, what are you doing now?

"So, what was that you were working on just now?"

"<>"

"Oh, that. ......"

Originally, it was one of the measures to find Lardus who escaped by shifting.

We are considering the possibility of detecting changes in mass, but there are many problems in terms of sensitivity and accuracy.

In short, it is very difficult to detect the disappearance or sudden appearance of a mass as small as a human being.

"...... Well, how about <>?"

An inspiration struck Jin.

"Huh?　Onii-chan?"

Jin bro?

"...... Well, let's assume that the transferred object has magic power, and the changes caused by its appearance should propagate through the free magic element (ether)."

"Oh, so that's what you're trying to detect."

"Oh, that's what we're trying to detect. Which is easier to detect, mass or mass.

Well, the free-magic ether wave, which we're used to.

I agree.

I guess so.

Waves that travel through free magic element (ether), that is, free magic element (ether) waves, are much less attenuated than radio waves.

This means that they are easy to detect even at a distance.

The only problem is that it is not possible to detect objects or persons that do not have magic power.

This means that if any object is transferred, it will be undetectable.

This was a drawback that could not be ignored.

"Hmm, both have their advantages and disadvantages. ......"

"Hmmm..."

"Yes," he said.

Then Saki appeared.

"Hey, there you all are. Are you considering ...... something?"

"Yes, I am."

Jin explained to Saki on behalf of the group.

"Hmm. ....... I'm sorry to ask a layman's question, but doesn't the free magical element (ether) vibrate when it is transferred?

"...... what?"

"What?"

"......" "......"

The following are the reactions of Erza, Jin, and Hannah, in that order.

"When you transfer, the free magic element (ether) is pushed away, even if only a little, so naturally it will vibrate, right?

"Hmm, that's a blind spot."

"Then maybe we can go there with an extension of the free magic element (ether) wave detector. ...... No, we can go there, Onii-chan!"

"Yeah, I guess so. ...... Saki, that's great!"

"Oh, yeah. I'm ...... glad I could help, okay?"

Saki's simple remark revealed a great possibility.

"Okay, let's run some experiments and see what happens.

"Before we do that, we should build a new detector.

"That's up to me and Hanna-chan. Jin, please prepare for the experiment.

"Okay."

Jin and his team were about to take a big step toward the development of a . .......
