Is this the end of the test, Ai?

"That's right. Let's leave it that way for now." Thank you for your company, Mr. Lassen. "

"No, no, it's just that I've never used such magic before." ".... I'm tired....."

Looks like the Eye's verification against Rassen is over.

Lassen sighed in relief when he heard the word "end of the eye."

Looks like you're pretty tired.

Although Lassen had a lot of magic power, it was only enough.

But for verification, they used magic stones of magic power to make holes in the ground.

At first, it was Lassen who tried to enchant Ai, but gradually his face changed.

Maybe it was the end of the sorcery.

"Ah, please put the hole back properly." If it collapses later, it will be troublesome. "

"Oh, no... I see, I'll do it."

But I don't want you to end up there.

Because a land full of holes is not dangerous.

So I told him to return the hole drilled by Lassen to the original ground.

I saw a figure with glittering tears in my eyes.

However, thanks to Lassen's hard work, the Eye's verification has been successfully completed.

I don't know what that means, but I think the talent to manipulate so much soil is amazing.

Besides, he said that he boasts more magic efficiency than Brother Arth, and decided to confirm with Ai what kind of information was gathered through verification.

"I see. First, let's talk about Ars Barca." Ars Barca puts his hands on the ground, sheds magic power into the soil, and activates magic. At that time, the surface part is the starting point for magic, and the amount of magic power used varies depending on the vertical, horizontal, height, or depth. "

Hmmm. In other words, when you try to build a wall, if the capacity is large, you will use the amount of magic power according to that capacity.

“That's right, so Ars Barca uses magic techniques to control the consumption of magic power, so when building a building, he uses magic shapes to match the finished shape of the building before shaping it. In that case, the magic power consumption of the internal cavity can be suppressed."

"Hmm. That's what I did."

"Yes, but there are still places where the consumption of magic power cannot be suppressed. It's underground."

"Is it in the ground?" That's because the surface is the starting point for magic power. "

"Exactly. For example, let's say Lord Ars Barca has created a cavity in the ground." If it is 10 meters long, 10 meters wide, and 10 meters high, the capacity is 1,000. But do you know what happens if the cavity is 100 meters deep from the surface? "

A thousand times a hundred means that there is a total of 100,000 magic power consumption. That's amazing. It's a lot different than digging a hole right under the ground. ”

“That's exactly the problem. Therefore, Ars Barca has never made much of a tunnel. Even if you try to create an underground passageway that leads to a deep place, the magical power consumption is too great.”

"But you created the Sky Kingdom." That's quite a size, though. "

“They also use external magic, such as the Atomosphere and the Labyrinth Core. Otherwise, Als Barca himself says, we can't easily build structures of that size.”

I see.

It is the power of Brother Ars, who has only heard a great voice from others, but is there a weakness in that respect?

Even if you can ignore it if it's shallow from the ground, it's too inefficient to tamper with soil above a certain depth.

I see.

That's why the magic created by Brother Arth is all that affects the surface.

Hmmm. That means Lassen isn't.

"Yes, based on the previous verification, I can confirm that the depth from the surface is not affected by the magic consumption."

"In other words, can you make a passage instead of drilling a hole in the ground as you please?"... that's terrible, isn't it? Isn't that supposed to overturn the root of the wall tactics? "

"That's right. As long as you have the magic power, you can pass from the outside of the wall to the bottom of the ground and penetrate inside." No matter how hard you defend it, it can be pointless. ”

Are you serious?

Is that the kind of guy that was left out in the wild?

I wonder if you've ever used magic like that.

... maybe there were no magic stones.

Now that there were magic stones, I was able to get a lot of magic to use.

Until now, however, magic stones weren't always available.

Not to mention, the magic stone with a lot of magic power could not be acquired by a civil builder.

Russell's own magic might have made it easier to drill the holes in the base when building the building.

That's why the ability to drill the hole itself wasn't that much of a concern.

That was close.

If he had been recognized for his true stature, he might have been used in combat.

It was only by chance that Eye realized the power of the man who was supposed to be here.

However, on the contrary, I wonder if we can use this to overturn the barrier tactics.

I felt like I needed to see how Lassen could help.
