In the IT industry, the building industry, the shipbuilding industry and other industries, it is better to finalize the specifications as soon as possible.

If we know exactly how to make it early, we can use it as a basis to create a process chart, place workers, and produce efficiently.

... but this is also something that requires a lot of know-how.

Whether it's programming, home or ship, a single item of merchandise does not have a clear answer from the beginning.

It is necessary to derive an answer to the name "what the customer really needs" from past examples and what is called a blueprint.

And this is the first modern outer ship of the Demon King Navy.

I don't know how much of a human army shipbuilding technique, but I built a steel ship ahead of the Demon King Navy. Based on the degree of development of land warfare weapons, it's not strange if you're already building a crossbow-class battleship or so.

The Demon King Navy ship, which began building to catch up with such a human army ship, was too ambitious.

There is naturally no precedent for ice battleships, nor can we cope with the know-how of wooden ships. Every time the navy requests something, the specifications will not change.

But the delivery time is unscrupulous.

Clearly, it is a landmine customer.

If this is a private company, we're going to refuse orders, but we're in the same army. Comrade to His Majesty the Demon King Hel Arche.

"So let's work together"

"... all the belly searches will bring your stomach. Besides, it's more important to be able to ship. each other."

"That's the thing. Leona, too, okay?

"... I'll help you if you don't demand any more performance degradation"

"We're not gonna cover it."

"Er..."

Well, supply lines, no. I want you to have a decent maritime rights fight with the human navy when you think about the issue of replenishment warfare, and I don't want to lower your performance even here.

for the transport fleet and also for the stomach of the barracks bureau that manages them.

The cooperation between Mr Sofia and the Naval Factory Clerk has already led to the assignment and review of the staffing by competency.

Regardless, confusion was initially seen due to the repositioning, but skilled shipbuilders are still different. He got used to me in a few days.

It also decided that it was more important than that. The head of each department was established.

The biggest reason is that the Barracks Bureau and the Naval Factory Clerk alone cannot cover the labor management of the shipbuilding technicians, but the presence of those who look directly at them in the field and direct them in technical and labor positions is still significant.

It will be their job to see how efficient they can be.

"This is the fourth block on the port side, but there is currently a five-day delay from the process table. We are rushing the work, but many people are unfamiliar..."

"You should turn personnel from the department you can afford. Mr. Sophia, where is the handcuff now?

"I don't know if you can call it a handicap, but the stern block is going best"

"Then a few people from the stern block, whether they can move... If you're in charge, can you please?

"About two or three of us would be fine."

"Okay. So let's take Legol and Diddy."

And every few days they and I set up a place for consultation and we report on each other's progress.

Where and how far along they went. Are we on schedule or behind, or early?

Did the assigned personnel make a mismatch?

Have you not exceeded your budget?

While discussing future plans and such, the part of the naval factory that hasn't decided on specifications is unattainable to lag behind or minimize waste.

No matter what the technicalities are, the station doesn't know.

So the barracks bureau looks at the whole thing and pushes the right person from among the heads of each department to the head of the tech - whoa, whoa, whoa, appoint them and move on as they pull everyone or discuss it.

"Dr. Calzette. My name is Salz and I'm from the stern block, but isn't this how we should build the hull skeleton section?

"Yeah? Oh, I see. I do wonder if these people can reduce it by about 30 people while maintaining strength...... I never had this idea."

And if you accumulate know-how, you can sometimes find efficient manufacturing methods.

Let the meeting know how to do it again and see if it's actually a problem. If we repeat that, we can make it more efficient at an accelerated rate.

........................ Phew.

"Dear Akira? What's wrong with you?

I watched the smooth turning project bogged down, and Mr. Sophia called out in the form of a peek into my face.

"No, I haven't worked in a while."

"... you always say it like you're not working"

"Oh, hey, that's not what I meant..."

What can I say? Yes, if you're worried about wandering around in your head, Mr. Sophia says, "I'm kidding," and then pretends,

"But I think I know. Because of us - I guess it's self-admiring to say - that when you look at it this way, you feel like you worked"

and continued.

From the naval factory office where we are, there's a view of the dry dock. Plan 501 was built there, and the skeleton is already nearing completion. I can see that this is building a ship.

"... it's finally next week"

"Yep."

Next week, the 107th day after construction begins, the biggest event for this 501 ship awaits.

It is the task of installing the Type 63 Demon Stone Combustion Engine of Ship A, the auxiliary engine of Ship 501, and the Type X Calzette Type 69 Demon Guidance Engine, developed by Leona as the main engine and brought in from the Demon Capital, in the central part of the hull, and making it ice marinated.

"... if this fails, I will return everything to the blister"

"It's not a metaphor or anything, it's scary..."

Damn, I don't make ice battleships.

But if we can do this hull, it'll be done even if we leave it alone already.

---

And seven days passed quickly.

Two carefully installed auxiliaries and one main engine are seated in the central part of the hull.

"Auxiliary machines are reliable institutions built on conventional theories of magic guidance, and the main machines are institutions built on new theories I've devised."

Leona explains the agency beside me while Leona leads the Demon King's Army Development Agency in command of the installation and coordination work.

Probably because I'm going to need it at work, rather than saying, "Understand the beauty of my thoughtful institution!" It seems that there are thoughts. My eyes suck.

"I don't think I know, but I ask for once. What's the difference?

"Yeah. First of all, auxiliary demon stone combustion engines, as its name suggests, use demon stones enclosed with magic as fuel to gain magic and propulsion from them."

"What demon stone do you use?

"I'd like something of high quality, but the structure of the institution means anything."

I see, with the steam locomotive?

That's whatever you burn, so besides coal, it works with heavy oils, light oils, kerosene, charcoal, electricity, and at the end of it, nitro or something.

But if you want to increase the output, you need to make it huge with it.

In a limited space called a ship, demon stone combustion engines like external combustion engines are limited by their spatial margins, and that's the limit point for output, apparently.

It seems to be the turn of the Leona idea fantasy agency, where even the same size can be expected to produce several to dozen times more output.

"Huh! This new institution devised by Leona Kalzette, the" X Kalzette-style Model 69 Magic Instruction Engine ", was finally discovered after many years of research into how His Majesty the Demon King Hell Arche is gaining that mighty magic!

Says Leona makes it a living reward to magically reproduce His Majesty Hell Arche's power.

The result was that supermassive demonic statue, "Magical Special Leona (abbreviated as Masre). However, I was still dissatisfied with that masre and was just doing some further research.

Even when the military station station was set up and the budget was cut, Leona, another achievement of the study of the reproduction of His Majesty the Demon King, which was being continued using the good Gone, is that it was combined with this magical guidance agency.

I see. So you're saying that Leona's demands were swallowed up there and she went out with Leona's madness?

Research is something that I don't know how to connect with.

The characteristic of this Calzette-style Type 69 demonstrator engine is that it does not require fuel. How delicious for a soldier station not to need fuel!

So how do we raise energy? Easy. According to what Leona described so briefly that she chewed it up and couldn't keep the original shape.

"If you say so, it is' an institution that produces from nothing '!

Apparently. And in theory, you get infinite output.

... what that dream institution.

Instead of the human army, isn't it technology that doesn't even have access to modern Earth mankind?

Regardless, infinite output is not obtained due to the durability problems of the machine, but it nevertheless obtains more power than conventional type engines.

And even more surprisingly, aside from saying that two auxiliaries are spare output devices, they also serve as starters for this demonic guidance engine.

It is obvious that operational problems, especially maintenance problems, erupt because they naturally accumulate two different institutions, but it is significant that fuel is not required.

"I see. I know exactly why local production of the agency cannot be done at the naval factory"

"Right? Blah, there's not enough production facilities for the Devil's Capital either. If we had a factory a little bigger, we could have a better performance engine..."

... Hmm.

I did a pretty unscrupulous naval factory reform this time, but if there's a chance that I'll do the same thing again in the future, it's also a hand in building a new naval factory.

Naval enhancements cannot be avoided which way, and if so, it would be more efficient to reject the creation of a new large-scale naval factory than to improve the narrow Nort Fork naval factory -

"Oh, Akira! Not if you say so! It's time to get started!

And Leona pulled it back into reality if she thought about it all.

Apparently, the final adjustment work is over.

"Huh? Oh, man. Finally."

"Yeah. Finally, this skeleton only ship will be covered in ice!

That's what Leona said and raised her voice at the same time as she raised her unconfidential chest, giving instructions.

"We're going to start building ice on the hull!

At Leona's behest, ice crews, mainly from the Bureau of Development, move. Otherwise employees evacuate to avoid getting caught in the ice marination.

First activate the Demon Stone Combustion Engine and use its energy to start the Demon Guidance Engine. It was the first startup, but Leona confirms the output has stabilized.

And finally, the time has come.

"- Freeze, start!

"Copy that. Hull freeze operation initiated."

It is the moment when the world's first ice ship was born.
