Magi Craft Meister

As Jin thought, Hannah was in her lab.

Hannah, you're here.

Speaking up, Hannah raised her face from the document she was considering.

Ah, onii-chan

"Brother Jin, what's wrong?

And Elsa was there with her.Looks like he was helping out with something.On the table are scattered pieces of paper with magic formulas.

Jin informed the two of the requirements for a visit.

"No, I heard from the old man that 'The Communication Wave Through the Magic Barrier' has been completed...."

"Ah, yeah, just in case, I did."

"Was it easy?

When I first heard about it, Jen remembered that it was not yet at the conceptual stage.



Magic barriers (magic barriers) are, in short, boundaries that prevent the transmission of free magic elements (ethers).

Therefore, the physical phenomenon cannot be prevented.

Fire attribute Fire generated by magic, or water bullets generated by water attribute magic are physical phenomena that cannot be prevented.

"Heating (heat)" and "cooling (cooling)" are magical effects that can be prevented on objects.

However, the most troublesome thing for Jin is that the magic barrier (magic barrier) does not communicate through magic... that is, free magic (ether).

For this reason, if a magic barrier (magic barrier) is stretched, communication becomes impossible.



But Hannah shook her head sideways.

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

Well then?

"Yeah, I said 'just in case'.I've created an alternative..... "

"Alternative means of communication?"

"That's what it is. Um...."

What Hannah explained to me was something that I was most convinced to hear.

"It's radio communication, Oni-chan."

"Is that so...."

Radio waves... electromagnetic waves are a physical phenomenon and cannot be prevented by magic barriers.Depending on the wavelength, physical barriers (solid barriers) such as light can also pass through.

"That's why it's annotated, and I didn't even report it to oniichan."

Was that so?

Still, the magic barrier (magic barrier) is very different when you can't communicate in time.

"Elsa Onee-chan helped me prototype the communication magic equipment."

Hannah showed me her bracelet-shaped magic tool.

Like a watch, there is a main part on one part of the bracelet.Sounds like a speaker and microphone.

"But hey, radio waves... I used wavelengths equivalent to 'medium waves' this time, but now they're blocked by objects."

Oh, I see.

Magic waves, which are free magic (ether) waves, transmit most substances, but radio waves are not.

"Isn't that ironic?I can't believe the radio waves that pass through the magic barrier are now blocked by matter. "

Yeah, well, yeah.

"Something like that happened, and I didn't report it to oniichan."

"Okay."

"I would like to use sub-free magic waves if possible."

Sub (sub) free magic (ether) waves are thought to be even shorter wavelengths than free magic (ether) waves, and even planets and stars can be transmitted.

It was thought that years were still needed to use this.

"Still, it's easier than ever to communicate inside and outside the magic barrier (magic barrier).Thank you, Hannah. "

"Ehehe, I'm not satisfied yet, but I'd be happy if I could help Oni-chan."

Hannah smiled happily.

Jin asks immediately.

"So, what were you doing?

"'Metastatic Detector'"

"Ah, that's it...."

Originally, it was one of the strategies to discover Lardus who escaped with the metastasis.

We are looking at the line of detecting changes in mass, but the problems are piled up in terms of sensitivity and accuracy.

The point is that it is very difficult to sense that a small mass like a human has disappeared or suddenly appeared.

"... yes, how about 'magic'?

Jin was inspired.

"Eh? Oni-chan?

"Jin?

"... well, assuming that the transferred object has magic, the changes that it makes should propagate through the free magic element (ether)."

"Ah, you're detecting it."

"Yes. Which is easier to detect than mass?"

Well, that's a free magic (ether) wave you're used to handling.

Nh, I agree.

I don't know.

Waves that transmit free magic (ether), that is, free magic (ether) waves, attenuate much less than radio waves.

This means that it is easy to detect even if it is far away.

The problem is that you can't detect objects or people that don't have magic.

This means that if something is transferred, it cannot be detected.

This was a disadvantage that could not be ignored by this.

"Hmm, both have strengths and weaknesses...."

"Nh"

That's right.

And there, Saki put out his face.

"Hey, was everybody here?... are you considering something?

"Yes, it is."

Jin explained to Saki in person.

"Hmm... The amateur question is, does the free magic (ether) not vibrate when it is transferred?

"... eh?

Huh?

"...... ah......"

In turn, Elsa, Jen, and Hannah reacted.

"When it's transferred, the free magic element (ether) can be pushed a little, so naturally it vibrates."

"Nh, it was a blind spot."

"Then maybe we can go with the extension of the Freedom Magic Element (ether) wave detector... No, we can go, Oni-chan!

"Oh, I see.... Saki, that's amazing!

"Ah, yeah.... um, if it helps, I'd be happy.

A worthless word from Saki revealed great possibilities.

All right, let's run an experiment.

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

"I'll do it with Hannah.Jin, get ready for the experiment. "

"Okay."

Jin and the others were about to take a big step towards the development of a "metastasis detector"....
