I was a little over 14 in no time.

Life is denser than last year, research, research again.

No Demon Crystal (Battery-less) Demon-making research I'm doing right now, and even a little bit of thinking about increasing my fiancé Laura's handle was a bad idea.

I made up a plan for Grand Rail Road, a non-refillable and operational transcontinental railroad using infinite demonic power (swelling engine) without demonic crystals, but as soon as the story got passed on to Wang Du, Dobbar and research funds came down.

Professor Marino says he's getting serious up there.

When you say railroad, the idea itself is simple.

Simply divide it into a power system, a transmission system, and an operating system to modular the demonstrators and connect them to the wheels.

All we have to do later is scale it up to fit what we carry, it's easy to think about, isn't it?

Well, it's not easy to make.

Then I received an instruction to conduct a long-distance transport operation test between Torquiiba and Ruefma, and it was already refreshing.

Professor Marino runs around the roots to rent a magic railway line that runs between Turkiiba and Ruefma, and I get a discipline waiver from Estomaon to get into research.

And the haste of the lab only increases when the date on which the route can be rented is set for the scheduled holiday of the entire route at the end of the fiscal year three months later.

There are people sitting around day and night, or sleeping bees on the reception couch.

I know what this feels like.

It's called Death March.

"Are you sure this works?

"In principle, we're totally with the railroad we plan to build. However, if you fit it in the size of a luggage truck, you don't have enough output at all, so you can't climb the ramp."

Me and Professor Marino were staring at a test-built demonic carriage in the corner of the parking lot at the School of Magic Conductors.

Demon guided carriages and demon guided railroads with demon crystals powered by demon crystals have been in practical use for quite some time and even exist like massive airships and tanks.

It's a huge technology that already supports critical social infrastructure, but it's costly.

I referenced the Magic Conductor carriage and incorporated the Infinite Magic Engine into something like a larger luggage car.

If the Magic Carriage had about six horses, this Magic Carriage would have about one cat.

Computationally, it should work critical.

"Then it starts."

Unsealing the demon around the engine begins to move as the demon makes a cocky noise.

Without aligning the quality, size, and characteristics of the demonstrators, there was no harmony between the demonstrators, and the output did not improve well and I struggled.

Even the Infinite Demon Engine is super low cost super low output, if you don't work out a little bit of an output increase, the size of the powered car will exceed the size of the city.

"Whoa, did it work?

Professor Marino is intrigued to peek into the wheel, but probably hasn't moved yet.

No fine dust has stepped into the line drawn in front of the wheel.

Took as long as the yawn seemed to come out, the magic car began to spin the wheel just a little bit.

"This is working, isn't it?

"Yes, Professor, it's moving."

"But if you hadn't drawn a line under the wheel, you'd be so nosy that you didn't know if it was moving or not."

"This output just stops you from stepping on pebbles, after you make it bigger than this"

"Hmm, toothpicks"

Professor Marino, who was initially examining the progress of the wheels moving closely due to something of a mismatch, also sat completely in the chair by the time less than an hour later.

I used to carry drinks and snacks, but Professor Marino sat in a chair and watched the wheels move all the time with his arms together.

Eventually, the demonic car takes about enough time to change the position of the sun to spin the wheel, and as I said, it stops stepping on pebbles.

"You've stopped."

"Right."

"But even though the wheel spins, it's important that it's moved, right?

"That's right! This is just a step forward for a spin on the wheel, but it's a great spin for magic."

"Mr. Schenker."

"Yes?"

"Can I have that expression?

That day, me and Professor Marino went back to the lab laughing and making everyone else suspicious.

Some cold night.

Me at the beginning of the lab and my fiancée Laura were dining with my father and my older brother.

It's a seemingly expensive restaurant in a safe neighborhood where civilian moon earnings fly quickly.

"So, uh, marriage means as soon as Sawadi grows up?

"Oh, I'm thinking about it"

"I'm also going to buy a house to go with it."

"You can stay at my house for a while."

"Laura's just having a hard time getting ready to move, isn't she?

"I just unloaded it. Give me a break."

My father looks amazing when I talk to Laura casually like that.

Ha, you're totally freaked out by the wizard.

"Hey, Dad."

"Duh, what's up? Muniel doesn't have salt today, do you want me to change it?

The salt gas is on, your tongue is nervous and paralyzed.

"I talked to Laura, and she's a family member because of her different status, right?

"Oh, yeah, you are"

"So if it's outside, whatever. In our relationship, let's say it's a proper family."

"What! And yet it..."

"Lord Brett, that's okay. I don't have a father or a mother anymore, and I wouldn't be so comfortable with my husband's family if they were real."

"Oh, really..."

I have an amazing contrast between my wandering father and my brother who is silently eating food when he tells me not to say a word.

I'm not even thinking about it. My brother looks like a big guy instead.

"This sounds like some famous booze, but let's get rid of the cup."

"A cup is not a gangster. We are."

"It's similar."

"No, it's not! My house is a clean, bulky (...) merchant!

"Fair enough, Lord Brett, I will hold on to his reins from now on. Don't worry, I won't let you."

"Oh, please..."

Put the liquor sent by the ex-military who treated him the other day before his father, who lowered his belly and leaned down.

It's from some famous brewery, and it seems like it's produced in limited quantities.

I don't know much about it, but my dad changed his complexion when he saw it.

"Whoa! Where did you get this!

"The military gave it to me"

"This is Sugar Hat! You existed! Is it real!?

"Well, well, Lord Brett. I get this stuff a lot."

"It's not something you can get..."

"Anyway, now it's inside, but it means a cup of parent-child stiffness... please, Dad"

"No, but..."

"I'm telling you I like you..."

I dumped my reluctant father, poured liquor into two glasses, and put them in front of me.

My brother said, "What about me? 'I'm pointing to the empty glass in front of me, but my brother will shut up and have some dinner.

"Well, Summon, I, Sawadi, would like to divide this cup."

"... please"

"Say hello."

The ritual began strictly as my brother raised an empty glass against me watched.

My father and Laura swap each other's slightly mouthed glasses for the other's glass.

The two silently drank it up and slammed the glass to the floor.

The glass was shattered and splashed, and now the cup of parents and children would have been exchanged.

Nobles and civilians, of course, it has no effect.

This is from me and Laura, to my father, the average man.

My heart is a family.

"Dear Lord Laura, Best Regards, Sawadi..."

"Yeah, but I might be the one to take care of it."

The father and daughter, who have just become parents and children, hold hands firmly and grin at each other.

Speaking of which, I was doing it by pouring my earlier liquor into my brother's glass, who started pulling his sleeve.

I'm with my dad, and my brother and I can't even cut the edge.

I don't rely on you for a bit, but we need to support each other.
