The hero magician wants to relax. He was too active and targeted for his life, so we'll start over.

Teacher Yuna Vendart, who teaches higher magic classes at the Actis School of Magic Knights, is my apprentice.

... Even so, I've done very little like a master, but she calls me "Master" and asks me a lot about magic.

I was originally hired as a school instructor, but now I'm taking over that class, and Yuna's still my assistant. I'm still a student at this school.

Students teach and instructors assist - I know it's an outrage if it's normal, but Yuna was only interested in magic, so she didn't care about her surrounding eyes and reputation at all.

That Yuna was obsessed with the toys I gave her.

A secret passage dedicated to magic cars in the basement of the Blue Lion Dorm. A magic car is placed in the hangar facing there.

That is the first magic car that I and Mr. Bell were in when we first came to the Kingdom of Verilardo. They broke down in the middle of the meadow, then they retrieved it into storage and left it there.

That's what's now in the hangar in the underground secret passage.

"Is the repair in progress?

If I spoke, Yuna, who was working in the car, gave me a peek in the face. On the desk placed nearby, the sandwich remained on the plate. I forgot to sleep and seemed immersed.

"Master"

Why, if Yuna is fixing my magic car, the trigger starts with her utterance.

'Can you tell me how to make a magic car?

Apparently I wanted to try and build a demon stone-powered automobile myself. I love magic research. I am a human Yuna. I guess it means shortage just to be able to drive.

Then I sent out the first magic car in the middle of a breakdown.

The magic car is an exterior model of the automobile in the world that I took, but its structure is quite simplified.... Well, that's because I'm not an expert in cars.

The basic is to connect the magic transmission line to the magic stone engine, which is the power, and move the operating part by running the magic.

For example, by stepping on the accelerator pedal, the demonic stone behind the pedal contacts the magic transmission line. Then magic occurs, which becomes a signal and is transmitted to the Demon Stone Engine.

Then magic flows from the Demon Stone engine to another transmission line connected to the gear for advancing, rotating the gear. The rotating gear passes through the axle to the wheel to advance the body of the vehicle.

The operation of brake pedals, gears and handles is basically the same flow. In order to enable these series of operations, it is essential to combine a magic transmission line that connects the motion unit to the Demon Stone engine with a magic character that tells the motion unit what to do.

Yuna was taught a whole lot about how magic cars work, how to tension magic transmission lines, and magic letters to get each part running. As for the missing parts and the necessary materials, I was supposed to prepare them for her... but she was stunning enough not to repair them and was obsessed with the production work.

Was it 23 this year? It was as focused as a child given a toy.

"Repairs will be completed shortly"

Yuna, often lacking in expression, strained her chest. That very big breast shook, but my gaze turned to a slightly more dodgy face than that. I felt like watching the toddler, and she looked adorable.

"Yeah, that's reliable. I'm glad to have an excellent apprentice."

I have never spoken of a disciple, but Yuna became more and more obsessed with the words I intended to joke about.

"It's an honor, Master"

"When this guy is safe to move, don't be able to make an original dedicated to you in earnest. Think about what you'd like right now. Until then, you can let him go."

"Thank you, Master!

Oh, whoa...... The powerful Yuna's voice was unusual when I did it, and I was a little surprised. Are you so happy to be able to make a magic car for yourself?

It was me who thought... etc., but I heard later that it is as a disciple to be given the tools of your master - in this case, a car. That seems to mean that the teacher recognized the growth of the disciple.

"Oh, yeah. Yuna, beside repairing the car, I need you to do one thing..."

"Do you want to rub your tits?

"... at this time, will you stop saying that in the face"

Yuna is Yuna, too, who says it without any shame, but then I guess I'm just a pervert. The right time and place is over.

Pinch one cough and re-compartment.

"I'd like to add one feature to my car... Air Conditioner - Wouldn't you like to try putting on an air conditioning device?

I mean, air conditioning. Yuna slightly enlarged her eyes because of the way she put it.

"What the hell kind of magic equipment is that?

"Here are three demonic stones"

I put each demon stone of fire, ice, and wind attributes on my desk.

My home production in the land of Willidis was going well.

Furniture and the like have not yet been put in, but the general room arrangement on the ground and second floors is being completed.... but it's hot.

"Safilo, indoor temperature, lower it by about two degrees Celsius."

Speaking with a moist sweat wipe, Safilo, the core that manages the dungeon, returned it with a magical tale of 'Copy'. If it wasn't under Safilo's control, air conditioning and fans would be a must, damn it.

"Master, Master Early is here."

Safilo has reported. I guess I went through the Blue Lion Dorm portal to see what was going on over here. Or is it dinner time already...?

"Is that enough time?

"Looks like a welcome."

Clerically Safilo replied.

"Okay, well, that's it for today. Let's make the third floor room tomorrow."

'... Master, if we have a third floor arrangement, I'll make a space for you?

"What?"

What did you just say? If it's arranged, I'll make it, right?

"Can you do that?

Affirmative.

……

I shut up. So, what is it? You mean I could have finished the process I was instructed to do without bothering to take a trip here, for example, when I was asleep or at school?

Affirmative.

Fortunately, the land is rich in magic, so with built-in magic even without a master, some work can proceed - Safilo told only clerically.

"... fantastic!

Really. Say that sooner!

Basically, what I wouldn't tell myself if I didn't say it from this side is that it sounds like a decent, unaccommodating machine. It is called the magic generation item of the material, it is called the automatic working function of this time...... I still have a handy feature, but unless I ask for disclosure, I guess I'll shut up, this guy.

You're like a calculator. I thought. If you push, you give the answer, but if you don't push, you do nothing.

When I taught Safilo how to arrange the room on the third floor, I walked out to return to the Blue Lion Dorm with Early.
