Demon Stone Jet Propulsion Engine - This is what I would call an engine mounted on a fighter jet for a versus a flying dragon.

Here's how it works in general. Flush magic, explode it in the combustion chamber in the engine, eject the generated combustion gas backwards, and gain thrust with its reaction.

In a rather abusive way, it generates explosive magic (exploration) in a row and flies with that energy.

Having heard that, Mr. Bell said, sarcastically distorting his mouth.

"Sounds like you're talking about flying in the air with your farts, huh?

"If there's enough propulsion in that fart to keep it running, can the sky even fly?

I rewarded him sarcastically, too.

An explosion by magic means that if you use a misthrill alloy for the combustion chamber in the engine, you won't have a durability problem. Mithril is an almost invincible metal against magic. The magic of the explosion won't scratch one. It is a rare metal that is difficult to obtain, but can be obtained if Safilo's magic power is generated.... horribly consumes magic, but sometimes converting dungeon demon stones to magic is fine.

The first thing I made was a rocket engine - the type that sprays propellant to get thrust in its recoil. The propellant here is, in other words, magic. Convert magic to combustion gas to gain propulsion as described earlier in Jet Propulsion.

Since the school had begun, it became a production activity back to Willidis after noon.

In the morning I put my face on the class, sometimes, Adventurer Guild, and then I build an engine. Assemble the parts based on the blueprints I wrote up with Yuna and the Shapeshifter team.

So we just tested the prototype aircraft Demon Stone rocket engine outside the eastern entrance of the hangar.

In short, during the first operating test, despite only five seconds of combustion time, I shook off the fixer and the rocket bullet. Nice to meet you. The engine flew away.

It was just explosive propulsion. I thought it was gay, but unfortunately no one noticed how funny this failure was, so I didn't get stuck.... you can say something, it's Yuna.

While I left the engine assembly to my disciples, I used Dungeon Core (Safilo) to expand the basement hangar and make improvements as a full-scale storage facility.

In the first size I made, it was already narrow. In addition to the magic car (sheep), seven prototype helicopters already exist. In the future, it is obvious that once an aircraft is built, it will be impossible to get in.

Sharpen the ground with range designation and strain floors, walls, and ceilings. Considering the number of aircraft and other things that will increase in the future, I took it quite widely, but I can imagine it will still narrow.

This is also due to the terrain. We crept through the hill with the Willidis Mansion and hit the east from its northeast, but there are limits to the space on the hill. When that happens, we either have to make it bigger for the first basement tier, or we'll have to smash through the next hill at the end of the northeast entrance and exit, or we'll make it as a second hangar.... let's think about that when we need it. For the calculation of Toranuki tanuki.

When I was overseeing the expansion of the basement hangar, Early came with the camera in his hand.

"Looks like you got lost in another world."

... keep the irony in my chest that this is a different world for me. Will the day come when I will explain to her that I am also from another world?

The blonde hissy-eyed girl looks around the hangar as she turns around the camera.

"It's like a majestic temple..."

As far as I'm concerned, I went for the future SF hangar.

Regularly embedded in the ceiling, Demon Stone lighting has a strong light intensity and provides sufficient light in the underground hangar. Well, if you keep the northeast and east exits open, if it's sunny during the day, that's where the light comes in.

"Jin."

Early's been pointing the camera at me, so I'm a piece sign. I heard the sound of leaving the image in the photo, or shutter if you want to compare it. Lately, you're totally a camera kid, no, a camera girl, Early.

Note that this piece sign may also be a recent fashion in Willidis. When it's taken on camera, I don't have a decision that I have to.

... I'm the first one to start.

"Jin lives in the future."

Early said she was squeamish next to me.

"We're doing more and more things that we don't even think about. It's amazing."

"Thanks"

I'll be honest with you. I hold Early's shoulder.

"You know, you seem to be working a lot more aggressively these days."

"You don't have to put up with this. If you want to, you can do anything here."

"Anything?

"Anything..."

Early cheeks on my shoulder.

"I thank you."

"Me too.... but"

"But?"

"You've been working on the helicopter lately, but you're a little worried."

I don't mind being aggressive, but trying to move a helicopter, the princess is aggressive. It is very different from when we first met.

"I'm interested in the view from the sky."

"Camera?"

"There's that, too."

Early lets go and stares at my face.

"When I was a kid, I wanted to fly in the sky, so I guess that's it too"

Is that the kind of guy who wants to get out of a princess life without freedom? Early childhood as a child who would have hidden her gender, not been able to get out much and had many restrictions.... I see.

"I hope you don't just be impotent. Flying in the sky is dangerous."

"You too, Jin"

Early followed my cheek with her finger.

"I'm worried about you."

"I'll do it right."

He is a man who wants to build fighters from now on. Naturally, if possible, I'm going to get on with it. Even if not, the title is once an adventurer and a magician. It is inevitable to stick your neck in the rough.

At that time, a corridor leading to the workshop was opened at the corner of the hangar.

Now that this prototype engine is complete, it's been transported. A tray for travel - a cylindrical prototype engine is on top of the unmanned self-propelled magic car I made the other day. This tray car moves in copy core driving, but there is no room for humans to drive, and it has a silhouette like a wheel on a giant hoverboard.

Yuna and the shapeshifters followed me around the tray car, and they looked at me, so I'm gonna nod.

"Well, Early. I think I could use a little help from you, too. I want you to get a camera shot of the engine experiment."

"Er..."

Early looked down at her camera and gave her a subtle look, so I said.

"Of course, shoot with a camera for the material. I'm not leaving any work footage on your memory camera."

"Yeah!"

Cheerful reply. We'll rendezvous with Yuna and move from the east entrance to the surface.

"Keep your distance, but you have the defensive magic, don't you? There won't be an explosion, but we need to be careful."

Speaking of which, number one blew up, didn't it?

Early laughed bitterly. I shrugged my shoulder, too.

"I think it's going to be okay this time."

Probably.
