"Oh, you succeeded, Gran"

"Don't try, Lord Ars. You could have changed the material of the magic doll from a rock to a hardened brick."

"Nice. Hardened bricks are much harder than regular rocks. I think it's metal. Plus, the color is white, so it's probably easier to use as a body than any rock I've ever had."

"No, that's not all. Being able to change the composition material of the demon guide doll to a hardened brick means that it can also be converted into a demon weapon. That could be bigger."

"Large your demon weapon?

"It is. Previously, there had been shortcomings in demonic weapons developed in the Brillian Demonic Power. It is that the constituent material of the demonic weapon that created the Spirit Stone as the nucleus was a common rock. As long as that rock was used as a material, the size of the demonic weapon could not exceed 3 meters."

"... well. He said the joint part couldn't stand its own weight? When a rock comes over 3m when it's a material, you can't support that weight on your knees even if it has self-repair functions, or something like that?

"Exactly. But if you can use harder hardened bricks, you can have bigger demon weapons."

"Fine. Shall we improve our demonic weapons? Change the material to a cured brick to increase its size. Yeah. How about, finally, let me take a mold from Tanatos and make it? It would be interesting if we could have demonic weapons too."

"I hope so. Confirmation of the behavior of the magic puppet shows that it can reproduce quite complicated movements. Let me mould it from Lord Tanatos in a giant state, and you'll have a demonic weapon that you can grab and fight with."

I continued my research into writing magic formations on that and this and spiritual stones with Gran.

The result was interesting results.

That was what turning the rock out of the spiritual stone until now into a hardened brick.

While this is simple, it can be said that it is a great achievement.

Anyway, hardened bricks are a much harder substance than bad metals.

It was conceived that being able to make it into a constituent material would not only affect the demonic guide doll, but even the demonic weapon.

Just now, experiment with the idea I came up with.

As a result, he succeeded in creating a demonic weapon that exceeded the previous size of 3m.

It was also the same 5m as Tanatos, and, moreover, it was not like the previous golem, but also made it possible to move as complex as a person.

This would also allow you to ram him with a weapon.

However, it seems that there are advantages and disadvantages.

If it was ever a demonic weapon, even if it was damaged and damaged, it could be self-repaired using the rock around it.

However, changing the composition material to a hardened brick seems to reduce the efficiency of the repair.

The amount of rock to cure the damage seemed to get bigger.

For that matter, there are aspects that are less likely to be damaged, but it may be more convenient to drop them off the airship with a rock type that is prone to fixing the damage.

Should I think about using it?

"But for now, is this where the study of demonic weapons, as well as demonic puppets, is a paragraph? The magic doll has been adjusted so that everyday operations can be done without problems, so all we need to do is supervise Lilina's body."

"Speaking of which, didn't Lord Ars say this before? I remember when I was researching demonic weapons, I said that it might be okay to have something that just spins."

"Oh, yeah, yeah. You did say that. That's right. Demon weapons and demon puppets have to concentrate on manipulating things in the form of people, right? No, I was wondering if it would be interesting to have something like a tool that keeps going around at a constant speed, no matter who uses it."

"For once, I did research on that, too. Instead of incorporating remotely operated magic formations, you should be able to write magic formations that have the effect of just spinning"

"Oh, you can already make it. Then why don't you make some? I just wanted to make some improvements."

"Is it something you want to improve?

"Yeah. I'm trying to improve my airship."

The study of making Aisha's dependent bill breathed a sigh of relief, but the study with Gran continues afterwards.

The subject of the study shifted from doll to power.

He remembered exactly what I told Gran before, and he seemed to look into it.

Gran had already created a mechanism for me to repeat the motion that a rock out of a spiritual stone spins when it can be magical.

That's what I wanted to build with it.

That was a new airship.

I have felt it since I floated Balkania in the sky as the heavenly realm.

That was something I wish I had a little more aeronautical capability.

There is still such a thing as an airship in Barca.

But this airship wasn't omnipresent either.

There are now airships that use flaming stones when they can use the magic of flaming ore.

They use high firepower flames, like gas burners, to warm up the air in the bag, inflate it, and gain buoyancy.

The airship that developed out of the balloon, if you ask me, was just a big balloon with a boat on the bottom for people to ride.

As a result, there were only about 10 passengers available, and moreover, the power to move that airship was the wind.

The air in the sky is constantly moving in complexity.

That's what the so-called airflow is.

And by letting a servant beast named Windmill Bird, who was good at reading the movement of the wind, pull the airship onto its airflow, the airship was allowing it to travel through the sky.

However, this was also a method that could not be used when the weather was slightly rough.

The more turbulent the airflow, the more likely the passenger will shake.

I often have trouble even when it rains.

Surprisingly, the conditions for boarding an airship were limited.

But with the rotational power developed by Gran, that would also change.

Or that the airship will also cease to rely on buoyancy utilizing flame ore, as it has done before.

Floating stone.

The floating stone, discovered in the divine realm and pushing Vulcania up into the sky, floats in the universe without any need for magic.

If you build a ship out of that floating stone and also attach it to a propeller made there using rotational power, you must be able to do something much more user-friendly than any previous airship.

In this way, Gran and I transformed our research from making dolls to creating flying vehicles that were okay for 100 people to ride.
