"Good luck accompanying Brother Lyon and Bite. So, what happened to the Urk army?

"Thank you, Master Ars. After that, the Urk army withdrew. We chased them quite a bit to make sure the Urks turned back to the city before returning."

"Right. I don't suppose there was any damage in the pursuit."

"Yes, I did it with caution, and the Urk Army's feet were dull, so it was fine"

"Hmm? They didn't retreat that slowly either, did they?

"No, it seemed painful beyond that there were many knights trapped in the night raid that Master Ars went to. When I marched, the commander level left the multitude of fronts, slowing me down as an army. The response to the chase was also timely."

"Right. Well, whatever it is, now you're saying that none of them are going to attack this Fort Einrad. Then why don't we wait for Carlos to drop the North City?"

"Right. I think that's fine."

After Lyon reported it, I exhaled hu louder.

Apparently, it's a relief for now.

The withdrawal of many thousands of Einlad recapture troops should not mean that their replacement will come any time soon.

For once, perimeter vigilance itself is not neglected.

If anything, there will be another report from the surveillance tower.

This brings us one step closer to completing the Einrad defensive mission entrusted to Carlos.

If so, I'll even write in reply to a letter from Lilina, who came the other day.

I started worrying about what I was going to write, spreading paper on my desk.

"Hey, Gran. Are you sure Atmos warriors aren't coming out anymore? Maybe the second and third monsters will show up?

"What is it, Lord Ars? After that, I thought you told me to gather information around you and that in the end the existence of something like that was not in any territory."

"No, I am. I dreamed about it. A giant figure hits me over a wall I've built... I thought it was just in that comic book, but I don't care if it's actually possible."

"Cartoons... what is it?

"Oh, no, it's nothing. Anyway, it means I'm anxious. If you had a giant like that, you wouldn't know if you could protect Fort Einrad here."

"I suppose so. But considering what happens if the Atmos warrior comes out, isn't there just about as much as raising the wall or developing a new weapon?

"What the hell. Don't you know how Gran was coping in the east?

"The awkward don't even know the details. There were many countries to the east of Mount Snow. It's hard to get information when the country is different, and there was a distance from the Atmos."

"Right. But you can't do nothing. I can't help it. Let's at least try to keep the walls high."

"Are we going to renovate the fort walls now?

"No, let's think about the future and see if we can make it new and magical. Gran, help me, too."

"You got it."

We cannot ignore the presence of a giant named Atmos' warrior any more than it actually was.

The outer walls of the current Fort Einrad are about 30 m high thanks to the use of terrain.

But I don't know if a giant who is physically capable and about 5m tall can be protected by his opponent.

What's more, on the 10m wall that can be built with [wall architecture], which I've been using a lot, I'm going to be overcome like when I trap it.

Again, you might want to make some new magic.

With that in mind, I started making new magic.

"Shall we put together the concept first? You're tall enough to protect the city from the giants for now. How much do you think I'd like?

"I suppose so. I think the more expensive you can..."

"That's right, but nothing too expensive, Gran. Basically, the fact that the others can magically build walls is an advantage of spells. Assuming I'm the only one with magic, that doesn't make sense."

"Then, while maintaining a minimum height, it also ensures defense. If so, it is good to change the material of the wall. Until now, it was a normal brick, and if it was made of hardened brick, it would be a hard wall without thickness."

"Right. So the material on the wall is a hardened brick, let's just try to make it about 1m thick?

"Isn't that too thin?

"No, the hardened brick has a metal level hardness, and I think a 1m thick would make it a pretty sturdy wall. Besides, I did it when I renovated Fort Einlad, but if I use the spell again just behind me, which I built a wall with a spell, I'll be able to make a wall of two-layer thickness. If you have to, you can cast a spell over and over again."

"I see. If so, if the thickness is reduced from 5m to 1m, then the height can be as high as 50m. But in that case, there's something I'm worried about."

"What do you care?

"I don't mind raising the walls, but I'm worried about the foundation when it's that high. If you pile a brick as high as 50 meters above the ground, it's a question of whether it will collapse."

"Right...... So you decide to make the foundation part of the ground when it's magically activated too? Why don't we cement the ground somewhat down there?

"You should do that. And I think it's better to keep it on the wall in the shape of a chest wall. Until now, I honestly felt it was a hassle to renovate on a magically built wall every time."

"But if we're gonna line up the walls on two or three layers of structure, wouldn't that get in the way? He said there's a chest wall."

"Hmm, I'm sure that's not true."

"Besides, the renovations themselves are easier to match the shapes you need sometimes, so let's make the walls that can be magically built simple after all. So say hello to everyone because we're going into the task of spelling it so that we can build a wall 50m high with hardened bricks"

"You got it. I'll take care of everything else. Lord Ars will concentrate on making magic."

All right, in the meantime, as a result of my discussions with Gran, I've decided to create a new wall magic.

I'll actually try to prototype it a few times to make sure it's in shape.

I even tried attacking the wall I built.

Do it to a wall prototyped to attack, try to hit magic, or hit with a stone thrower with enhanced physical abilities with magic, and fix it if there's anything that bothers you at all.

Thus, the determined wall is finally magically remembered with [storage] to crush and spell even the keywords that become spells while reproducing it.

That was how the magic of creating a wall 50 meters high was finally completed.

It was in this way that a new magic could be created by simply casting a spell on a wall of unprecedented height that became aware of the giant [wall of Atmos].
