"Total! I've been waiting for you!

When I showed up, Iberis, sitting on a counter co-located in the lab, waved like a child.

Next door is Suey, who looks a little dazzled by Iberis' good health.

Trash and garbage are still scattered within the lab, but I found only one painting neat and tidy.

Is the mysterious machine at its center the reason why I was called in this time?

"Iberis, it's been a long time..."

"That's right. I see him once a week."

Iberis had generally come to visit our store once a week, even if she was busy.

Most of them are also accompanied by Gongora. They talk about keeping Iberis alone from walking out in the middle of the night, but I often see Iberis as a better guardian in my eyes.

"So, what did they call you today?

"Nfu, that's me, that's me!

The same machine that Iberis is pointing at when he says he's allergic is the one I just laid eyes on.

"What the hell is that?

"Before I explain it, I think you should try it once."

It was sui that answered my question. But the identity remains a mystery, and Rye's reaction comes back to life behind my brain earlier.

"... are you all right?

"What?

"No, safety and all that"

"... so what?

Sui gives me a slightly annoying look.

But to pull back a bit here, I'm too scared of the information I purchased.

"No, 'cause Rye just says it's okay, and as much as what kind of device the hell it is, you can tell me, right?

"... then I can't surprise you"

Sui didn't shake her neck vertically when I asked her with a little emotion.

I can see a glimpse of pure curiosity from that expression, but that curiosity scares me now.

Iberis, who was watching next door, laughed at our exchange.

"Haha, it's okay. The total may be too worried!

"Iberis?"

"I'm the one who designed this machine. Sui feels like a starter and advisor, so I guarantee safety!

Don, and Iberis slapping his chest.

Looking sideways at Sui, he seemed slightly unwilling but nodded at what Iberis had said.

... If you're going to push your heartbeat that far, it looks like you can trust it for now.

"... well, if it's safe"

"Well, even if it sucks, you'll never die."

"Wait, is it possible that there is something? What am I supposed to do?

"Mm, it's okay. It's okay."

It is an anxiety which, at ease, has been pursued.

But they don't take it any further and just tell each other something by sight.

When that was done, Sui stood up and spoke gently to me and Iberis.

"Well, I'll be out of the room as planned."

"... oh, dude?

As it is, Iberis also rises up fine as she drops Sui out of the room.

And he pulled my hand and towed it to the front of the machine.

What is this' machine '?

From what I've seen, I know it's got speakers on it. Then buttons that don't know what to use for and categorical wiring. black box-shaped mysterious units that seem to be their source of power.

Seriously, the more I look at it, the less I'm going to know.

Looking at it for a while, Iberis shouts out.

"Hmm, I guess it's time. All right, put your hands on that box for a second."

"... you know what?

Put your hands on it as they say.

I was sober. Other than that, I'm not sure.

If you think so, the letter floats on the outer shell of that box.

I know it's a letter in this world. It says here:

"The waves of life, the ancient intentions, what I seek is the appearance of my soul."

"The waves of life, the ancient intentions, what I set out to be in this world."

"This."

It's not on the level that I remember.

There are only two magics that I can use in this world.

It was a chant of 'Ammunition' and 'Unammunition'.

"Mmm, you're up and running."

"What is this?"

"Be quiet, I'll connect you soon."

Iberis puts her hand firmly on her lips and urges me to remain silent.

Immediately after that.

Through the speaker on the device, there was a sound called Lilli.

This is, like.

Looks like a phone call.

"You can let go of my hand now. Press the button."

"... oh"

Iberis prompted me, and I pressed the button.

"Success, I guess. Total, can you hear me?

From the speaker that was mounted, he did hear Sui.

In the meantime, I turned to the speaker I was connecting to, and I replied.

"Oh, I can hear you."

"Success. You were safe, weren't you?

All I could do was return a dry laugh to Sui's voice, who was just a little bit good at it.

"The prototype means success, and this device will be named 'Voice Sending You One'!

When I pressed the button again, the call went out, and then soon Sui came back.

Sui looked uncommonly floated, playing hi-touch with Iberis when he came back.

When I asked again about the machine, the answer was Iberis' dialogue earlier.

"Iberis is a genius to get here in a month."

"No, no. I couldn't have done it without Sui's help. Magic is a tease."

"That's not true. It's a big deal to understand my theory and be able to apply it"

Two girls who ignore me and compliment each other.

Waiting until I had no choice but to finish that exchange, Iberis and Sui turned this way like they finally remembered my existence.

"Oh, total sorry. Is that a question?

"No, I want you to explain a lot of questions."

They laughed at my words.

No, did these two want to explain?

This may have gone faster.

It began abruptly, outside Dr. Sui's magic course.

Today, it was due to the difference between the magic devices used on a daily basis and the machines.

What is the decisive difference between the two?

The answer in this world is:

The former is what people do with magic to start and function,

The latter seems to be something that works independently, even if people don't give it magic.

The tools developed in this world are basically the former. This world consists of the use of magic, such as stoves that activate when you give them the magic of fire, or water supplies that activate when you give them the magic of water.

Conversely, 'cold tables' and 'showcases' in our stores, they are not. It automatically draws power from the demon stones of "Wotta" and "Gini" and will continue to function until you receive a new order.

I guess the big difference between a magic device and a machine is the difference between using 'magic' or not to press the switch.

And he can't say either of those devices this time.

"It is a machine in nature, but it is now a magic device. I wonder if that's right."

"What do you mean?

"This machine is probably a 'fifth attribute' machine built in the world."

"fifth attribute"

It is an attribute that appears in the story from time to time but is not clearly known.

What I know about it is that the study of the fifth attribute has not progressed and that I have a talent for the fifth attribute for some reason.

"In the first place, the current machine uses demon stones for power, is this okay?

"Oh. You're separate from the machines in my world using electricity."

There is no such thing as a power generating device in this world.

What is more, there has also been no development of steam engines.

I guess I don't need to develop other energies because I have an all-purpose energy called magic that my world doesn't have.

"The magic device is with you. The difference between the two is that the magic device uses the Demon Stone as an 'amplifier' and the machine as a 'power'"

"Demon Stone means there are many uses."

Demon stones are substances specific to this world.

If you let Sui tell you, pure magic has crystallized, apparently.

Its applications vary and, in addition to the two aforementioned, also become materials for potions.

"It's not clear because there are various hypotheses out there about what magic is in the first place. However, it is a common theory that consuming the magic of Demon Stone does not reduce its total quantity by itself, as it is naturally dispersed in the atmosphere."

"The Law of Magic Mass Preservation," you name it. Right. "

"... you know me well"

Jokingly, they really have that name on them.

The translation effect is not insulting.

"So back to this, this device can 'send audio'. And I use the magic theory of total" ammunition "and" ammunition release "for that principle. Therefore, the machine of" Class V "."

"First, I don't know where it is. Why would the magic of making ammunition and disarming it create a machine that sends audio?

Set aside the fifth attribute, the first question was there.

My magic takes the object in the form of 'ammunition' and returns that 'ammunition' to its original object.

Also at the stage of being 'ammunition', shooting it out with a gun makes it 'magic'.

I thought it would work like that.

To my question, Sui answers slowly, looking a little lost in words.

"... that's probably the essence... no, essentialization... you're not. The convergence of magical principles..."

"Sui wants to say something. I'll explain."

Side by side where Sui couldn't find a good word, Iberis starts explaining as she hands crossed.

"What about total magic? It's not the magic that makes ammunition, it's the magic that 'replaces' everything in the form of ammunition."

"Replace?"

"In the words of the drone...... 'compressed' and 'thawed' I guess"

"... ho"

I nodded as I watched Iberis squeeze his hand tightly or let it go.

"Compressed" and "thawed"? Well, it's a somewhat easy expression for me to understand when I was in engineering.

'Compressed' and 'unpacked', as I imagine, means re-compiling the information that the data has into smaller pieces of information and restoring the re-compiled information in accordance with the rules.

In digital relationships, compression and thawing can be attempted in different ways, but I guess that's the same in the magical world.

"In short, it is the magic of 'ammunition' that takes the form of ammunition without question with 'magical handling' what is there. So undoing it is the magic of" Unammunition. "

Magical processing is probably an area that Sui was studying.

Maybe it's a pungent world from what I've heard.

"In other words, this device compresses' audio 'with' magical processing 'to send and receive. You mean the machine that defrosts it and exchanges it again, right?

"Maybe that's what I mean!

With Iberis' energetic nod, I'm refreshed in my magic theory, too, but I kind of figured out the principle.

It means that we are using 'magic' to exchange what we are doing on the 'phone'.

"That's it, but then, what's a machine in essence and a magic device in its current state?

When I ask, Iberis returns the explanator to Suey.

Sui slowly approached the device and touched the box-shaped power source I had just put my hand on.

"This power. No, I don't."

"... None?

"In this world, no magic stones of Class V have been discovered."

When I saw Sui's sinister face, I remembered a little of the laws of the four major attributes of this world.

There are four basic attributes of this world.

Windy 'Gini'.

'Wotta' of water.

'Salam' of fire.

'Tayla' in the dirt.

That's four.

And what doesn't belong anywhere in it is called 'no attribute'.

'Fifth attribute' is not included in this.

"Without the demonic stones of Class V, there is no power to move the machines of Class V. This means that, in principle, even if you can build a fifth class machine, you can't actually move it."

Even if Sui releases his hand from the power source all the time, the machine has been running for a while.

But it also slowly slowed down after time and eventually stopped moving.

"So, what was it moving just now?

"Instead of having no Demon Stone, it means that I or the total originally had a lot of Demon Power in Class V doing the power instead of Demon Stone"

I see, so essentially a machine, but actually a magic device. So?

I built a car that runs on the engine, but I don't have the key fuel, so it's like I'm pushing it with my hand. Then I can't say I'm in the car.

After I thought about it that much, I thought, uh...

"... is that not dangerous? If they suck too much magic, they're gonna have magic deficiencies, right? So, the fifth attribute doesn't have a demon stone, so you can't even make potions, right?

To my simple question, Suey and Iberis turned a blind eye at the same time.

The reaction just seems to affirm my doubts as much as I did earlier.

That's right. I've never heard of Class V clearly before. That would mean that Sui thought the attribute had nothing to do with the potion.

Until I found out, the unattributed Demon Stone didn't show up for a similar reason.

And if there's no demon stone, there's no potion for it.

Does not the excessive consumption of magic power of Class V entail danger?

"... well, the total would be fine. It's safer than that porch."

"I mean, it was dangerous."

"... you were okay, weren't you?

That voice was like a kid before he got mad at me for playing a prank, and I leaked my sigh.

Perhaps there was some experimentation before I got here.

And you called me because you decided it was safe.

Sometimes I blame you too much.

"Anyway, the experiment was a success. But as it stands, it can't be used."

I conclude. In the end, it makes no sense if the power problem can't be helped.

If you don't have power, you won't move unless someone supplies you. I mean, in order to treat you satisfactorily, I have to supply you with magic all day. Then I can't do anything.

But I waited there like Sui was somewhat in a hurry.

"Not so! Promise each other beforehand, time each other, and you can make the most of it!

I face the sudden reaction of Sui.

Iberis interrupted with a nisci and a grin there.

"That's why I'm here. This machine, at one point, was completed when Sui brought the idea to the border."

"... one time?

"After the general found out he was leaving the city in training,"

"... ah"

That's where I finally realized what this device was all about.

This is a machine that was built just to allow me to get in touch with the city even after I went to training.

That's what Suey and Iberis worked so hard to make.

"Bad sui. I didn't realize."

"... that. Nothing, because you miss me, or that's not what I'm saying."

"I know, I know."

I know that even if Sui doesn't tell me.

I said with a slightly bewildered look on my face, a smile on my face.

"I mean, you worked hard to see how the store was while I was away, the twin questions, and all that stuff about customer service, didn't you?

"... eh"

"Right. That's the owner. No, I got one less problem with my job because of this, too. That's all Sui thought about the future of cocktails."

"... well"

To my much guesswork, Sui looked somewhat uninteresting because he was deprived of the opportunity to explain.

But it's important.

Asking seniors questions at that moment if they have any doubts is the fundamentals in these professions.

I've never had a better solution to those problems than to leave a store open for months.

Slightly constrained, but such is no big deal compared to the convenience of this device.

I want to be grateful for my sense of responsibility as the owner of Sui.

"Thanks Sui! Now you can go to training without worrying!

"... you're welcome"

I grabbed Sui's hand and thanked him.

She remained with a delightfully regrettable, very complex look on her face.
