Once transferred, Sage, I was reincarnated and became the son of the Demon King. ~ Eh ⁉ The sixteenth place in throne inheritance would be too low ~

"So do you want to move the mansion"

That's what my sister Izadra said and slapped her hand.

Then a guard soldier came in who was outside the room.

"My lord, are you calling?"

"Activate the Mansion. Keep the soldiers in the garden. As soon as it's over, activate it."

"I'm in awe"

A soldier graciously left the room.

When I dropped that back off, I asked my sister.

"Hey, sister?

"Uh-huh. What is it?

Unlike the earlier pissy, tight voice, my sister moans her hair with a sweet voice like sugar.

I asked while I thought there would be too many gaps.

"What do you mean," Startup "?

"... you'll see."

I thought about how to tell it and then I answered.

It means it starts, so it probably works. The question is how does it work?

I guess that's what I said because I thought if I saw it, I'd know how it works.

Then why don't you wait for it to move?

"More than that, Lewie"

"What?"

"Tell me what you've been up to.... although I know quite well what happened from Altria's report"

Yes, the second half didn't sound good, but didn't you say anything weird?

... well, okay.

I thought so, and I told him what had happened since I came to this continent. [M]

When I spoke up, Sister Miriam got mixed up. [M]

That's what I was talking about, and the door knocked.

"My lord, the corps has been accommodated. It starts now. '

"Okay."

"Bye."

That's what I said and the guy who knocked on the door walked away.

Well, how does it work with startup?

Is that it, like some manoeuvre fortress with legs coming out and moving? Or, like, Caterpillar's out and moving? Or let the big warcraft tow you?

I was excited about how it would work.

Waiting like that reminded me of a feeling I had tasted in a balloon I had ridden in my previous life.

Rather than going up at speed like an airplane, the feeling of floating a little bit.

Could this be.

"Floating?

"You're right. Lewie."

My sister strokes her head to praise me for getting it right.

"When we found the mansion, we modified it to float in the sky with a device using the demonic stones of the wind. In addition, by installing hundreds of magic cannons so that they can fight the sky's warcraft, and by constantly expanding the magic of the junction throughout the Mansion, the effect is that increasing the speed will not be affected by the wind. And even more."

My sister kept explaining, but it wasn't in my ear.

There was no technology like this when I was in the country. Does that mean I've developed it since I left the country?

I can't tell you how much I would like to see you develop this. [M]

I also heard that the magic that carried my brothers was developed by my sister and taught to Sister Rosé.

Could it be that if I weren't here, the technology of the demonic kingdom would develop?

I thought so, but on the contrary, politics is going to be a big deal.

My brother's struggling. You've been saying that.

If I go home now and then, will my sister do her job? But then don't think it makes no sense to leave the country.

But my brother seemed like a tough guy.... if it's okay to return home occasionally.

When this is over, will you tell me the magic that carried those brothers to your sister?
