Across Rosalia in Immortality Brigade alone,

Ismas Assault,

rescue of the king of Dwarves,

Everything went well.

I mean, it was good enough to go too well and scare me, but it wasn't all successful yet.

Negotiations remain with Gunter, king of Dwarves.

Back in the city of Ivaris, I invited Gunter, king of Dwarves, to the reception hall.

Not as a prisoner, but as a guest.

Or it looks like a demon tribe here, holding them hostage like the guys at Ismas, forcing the Dwarves to work.

There's also a way.

That was a more demonic way of doing things, but I knew exactly how pointless and unprofitable the act was.

You may be able to move people with fear, but it's impossible to work people with fear.

People never work if they don't have anything in return.

That was proven by the king of Ismas.

Even if he succeeded in captivating the king of Dwarves, he could not have made the Dwarves obey.

I didn't mean to make the same mistake.

Gunter was already sitting in the reception room.

Orders Sati to serve tea.

She's awed, and when she bows her head, she brings tea in the wagon.

"How many cups of sugar can I add?

The maid, Satie, asks Gunter, but Gunter shakes his neck to the side.

"I don't need sugar. Put me some distilled liquor instead."

Satti rushes to bring distilled liquor.

I guess it took a little while because I, the owner of this building, don't drink much.

When Satti brought the distilled liquor,

"How much do you pour?

asked.

When Gunter silently takes the distilled liquor from Satie, he does not pour it into the cup, but puts it on his mouth as it is.

It's like drinking water.

Satti whispers in my ear.

"Mr. Dwarf really likes alcohol"

"... oh, it seems so"

Gunter opened his mouth when he came up with the thought that this would require a barrel rather than a bottle. I'm drinkin 'up here.

First, I want to thank you for saving my life.

He bows his head when he says so.

Apparently this king is an honest king.

Civilians, no, even demons would be grateful if they were grateful.

I decided to get down to business when I gave him the right payback.

"I have a favor to ask of Master Gunter, King of Dwarves"

Gunter slowly shakes his neck to the side.

"I'm not a king anymore"

"... what does that mean?

"My kingdom, Wilheim, perished a long time ago. Nothing would be more hilarious than a king without a country."

"... I see"

"Nushi gives me courtesy to Washi, but that's not necessary. You just have to treat me like an old man."

Having heard the words, Lilith speaks familiarly to all "Bye".

Then he took the cylindrical one that had been placed on the couch between the receptacles, and put it on the table.

"Grandpa, can you make the same thing as this?

Although disrespectful to the king of one country, Gunter, as the foreword suggests, takes the volcanic gun in his hand without looking concerned.

Gunter is a dwarf at the same time as he is king.

There's no way I can't remember your interest when I look at this hand machine.

Change the color of your eyes and take the gun.

"What's this?

It's called a fire rope gun.

"Hinawaju?"

"We put gunpowder and ammunition from the tip of the cylinder, we light it, we burn gunpowder, we fire iron ammunition at high speeds by its explosion"

"Is that some kind of magic?

No, it's science, and I'm going to stop.

"Think of it as a form of alchemy. Exploding a material called gunpowder produces combustion gas. Normally when it explodes, it disperses, but when it explodes in a cylindrical iron cavity -"

"That energy is transmitted to one side, and bullets are ejected at high speeds."

"Exactly."

That's the king of Dwarves.

He understood everything with just a brief explanation.

Then they will also understand the parts and screws that are most needed to make a fire-rine gun.

When I took the screw out of my nose, I kept asking.

"Can you mass produce the same thing as this?

and -.

Gunter grabbed the screw and frowned.

"That seems simple and complicated in shape. It's like a spiral staircase."

"That's right. That spiral structure is important."

The helical structure enables the object to be firmly fixed. That's the strength of the screw.

If you don't seal the bottom of the gun with this screw, the fire rope gun won't be complete.

"Do you think you can make it?

I ask again.

Gunter returns one frown motionless.

"I can make"

and -.

Listening to the words, Lilith adds, Shaggu, but Gunter, however.

"It's impossible to mass produce something of this shape. Collecting skilled Dwarf craftsmen would be the limit of a few a day."

"... I see, is it still true"

It was the answer as predicted beforehand.

"It will sharpen each bottle. Such a delicate thing. We may not be able to reproduce it, but it will be difficult to get the numbers together"

Gunter punctuated the words there, "Something like this in the first place. Who the hell made it?," he asked.

I'm Japanese from another world, it would be easier to say, but I would delude myself, "It's a secret".

However, I had an idea how to mass produce this screw and the dot.

Regardless, my hands are not as clever as the Dwarves.

Speak to this wise king and he will make it up, and that's why he went all the way to Ismas.

I'll tell him how.

Modern knowledge comes in handy at times like this.

Gunter opens his eyes wide when he hears how.

"Was there such a way!?

Again, Gunter seems to have come up with a method of mass production of screws just by listening to the story.

After all, the king of Dwarves is no exception.

I understand instantly as long as I give you the idea, and the equivalent.

No, I'll make something more than that.

Now the prospect of screw mass production, or iron gun mass production, stood.

Later, we gather Dwarf craftsmen and just go into mass production, but the problem was at that price.

I'm not going to let anyone else just work.

Give in the most powerful weapon, the cannon.

I was going to make provision for that.

I propose to the King who is still excited and cold.

"Your Majesty Gunter, if you will mass-produce this volcanic gun, I would advise the Demon King to rebuild the Dwarf kingdom at the dawn of his unification of this world."

Gunter's showed face when he heard the words was the best thing of the day.

He opened his eyes wide and said, "Are you serious?," he asked.

I'll return it in a nutshell.

"The Demon King will give you permission."

"- What guarantee do you have that I can get your permission?

I answer honestly.

"There isn't. Besides, you won't be able to make this a pledge."

"Then how can you believe that story?"

"It's just my word. - So far."

What would you do if you broke that promise?

"Then beat me with a gun made by Lord Gunter."

That's how ready I was.

The Demon King cannot, in his position, make a promise to the King of Dwarves here and now.

There's also one thing about Basteo the other day.

Because if we show a compromise attitude here to the King of the Diaspora, we will not show it to the other Legion leaders.

Only if that demon king.

That girl would definitely come to the same idea as me.

I believed it and dared to bring up the name of the Demon King.

If that promise cannot be fulfilled, as the foreword suggests, you can give this man his life.

I looked into Gunter's eyes with such readiness.

- Has that readiness been communicated to him?

Gunter slowly shook his head vertically.

"Fine, let's make a proclamation and gather the craftsmen of the handsome Dwarves in this land of Ivaris"

Gunter has asked to shake hands when he says so.

I hold that hand.

Thus a covert alliance was formed between the Demon Kings and the Dwarves.
