"Amazing, Brother Ars. What is this? Looks like they're making something pretty big though."

"Oh, Kyle. You've come to a good place. What do you say we ride together? It's a new ship built with Gran."

"Heh, this is an airship. Sounds like a big difference compared to previous airships. It's kind of different."

"Sort of. But you didn't just change shape. I'm sure you've improved your aeronautical capabilities."

It's been awhile since I started studying airships.

Kyle came to see how Gran and I were doing.

I raised my surprise when I saw the airship that Kyle was becoming new.

What Kyle saw was not a substitute for an airship.

An elliptical airship that until then swells the air with flames through the torso of the cloth and flies through the sky.

That changed shape a lot. I think that's a good thing to call a plane.

First, the overall silhouette had changed dramatically.

The torso was barreled and winged on both sides.

A propeller is mounted in the middle of its protruding winged portion.

There will be two propellers for one plane because there are wings to the left and right of the torso.

For that reason, the silhouette alone was a complete propeller plane.

It took this form because it still brought knowledge from previous life's memories.

It is significant that it is a form studied over the years to attack the greatest enemy in flying the sky: air resistance.

It is easy to float because it is made using a material called a floating stone, but it was still best to make it similar in shape for it to move forward.

Essentially because of its floating stone properties, it floats on its own even if left alone.

Therefore, the ability to adjust altitude was also applied at once.

It uses some of the magic weapon technology.

Send magic to the nucleus of the Spirit Stone and create a heavy rock.

Added the ability to similarly adjust altitude by changing the weight of the plane with its rock weight.

By the way, when you get down on the ground, you have the disadvantage that if you don't keep it on the ground with a rope or something, it can float on its own, but well that's about as good as it gets.

And the propulsion at heart diverted this from the technology of demon-guided weapons again.

It succeeded in improving the remotely operated magic formation of moving the rock giant at will, causing a rotating motion and thereby turning the propeller.

The hardened brick parts that emerged magically in the nucleus of the spiritual stone rotate by the will of the driver, thereby turning the propeller of the wing portion.

This propeller acts on the air to create a force to move forward.

It also changes a lot technologically compared to the fact that until then the airship just rides the airflow stream, or it was a primitive thing to string and pull on a few servant beasts named Windmill Birds.

And that also made a huge difference in speed and operating distance.

I had to travel slowly over the sky if it was ever there, whereas on this plane I could travel pretty fast.

Moreover, in order to use the floating stone of floating in the universe, we can distribute all the magic we can have into propulsion.

The distance that could be advanced in a day also increased overwhelmingly.

"Heh. That's amazing. How many people can you ride?

"If I pack it as this demon-guided airship I'm building right now, can I get about 200 people on board? Well, it's gonna be tough riding for a long time because your seat's gonna get tight."

"Still, you can ride 100 people even if you cut it in half. Much better than the number of passengers on the previous airship. But you don't build bigger ones?

"I wonder if it's still important to improve this demon-guided airship now. The shape of the torso and the shape of the wings need to be improved, as does the propeller portion. Besides, I'm going to have to indulge in one of the inner chairs."

"Hmm. But that's really funny. Especially I find this mechanism of rotation interesting. Sounds like a wide range of applications, doesn't it? Looks like it could be used for other things as well as airships."

"That's right. If this succeeds, we'll be able to deal with the ground and the water."

"Ground and water? Oh, well. It can also be used for trains and regular ships."

"That's right. Especially trains. You could aim to be practical early on. Anyway, now that Valkyrie is pulling, if the Magic Train is complete, it will be day but night but it will be possible to travel."

"Nice. All right, then I'll work with you, Brother Ars. Where's the rotating mechanism?

"Then Gran must have made some. Over here."

After all, you mean Kyle is also a boy?

The moment I saw the vehicle system, the color of my eyes glowed and offered to develop the train myself.

I started making it and thought, "Making a ride is deep.

Speaking on a Magic Guide airship, performance changes gallantly due to the angle of the feathers, the structure of the propeller, etc.

In the meantime, Prototype One is finished, but we found a place to improve it.

As a result, trains, ships, etc. that I thought I would build next were behind me.

If Kyle is going to help me with that, I can't be more grateful.

Anyway, with Kyle's brain, the simulation of the parts that have to be structurally calculated will be over in no time.

Thus, Kyle's cooperation led to a dinosaur evolution of land, sea and air vehicles in the Balkans.
