In the 1st Battalion Command, even though it is late at night, Captain Rover himself has responded to an emergency communication by demonic props sent by Morrow.

"So calm down, darling. Explain why."

'So we can't go into more detail here than there is a possibility of a magical eavesdropping! Anyway! During the battalion, no, send me two, no, three of the fastest legged flying dragons (Wyburn) in the kingdom, ASAP!

"Can you do that without knowing why!

Admiral! Just do what Dar says! This is no joke. If you suck, kingdom, no, the world rocks easily!

You just decided it wasn't just every time, the general decides to do what they say for now. Once it was decided, the movement was fast, only to the person who was said to be decisive and a fierce warrior.

"Okay, I'll figure something out, but I'll do as you say for now. Instead, if it's content, I think the neck is about the torso!

'Thank you! And please send the Ombrey one over!

"Ombrey, huh? Why did you take him... No, I get it. Send it right away."

Apparently, you'll be able to send reinforcements safely.

"Totally. If I don't hand this guy over early, he won't get any sleep."

At the end of their gaze was a piece of dirt magically hardened mud - a piece of mud firmly carved in the footprint of a work boot (...).

There's a reason why you two got so upset in just your footsteps.

When it comes to shoes in this world, they are wooden or leather shoes, and easy walking is leather shoes but expensive for that matter. Since no rubber or the like has been discovered, the soles of leather shoes are also made of leather, which is difficult to damage and slip easily. In the army and elsewhere, iron shoe soles are struck to prevent slipping, but wet rock and stone floors are still slippery, and the shoe (shoe) often falls out, making maintenance even more troublesome. Carving a pattern like the "footprint" found across the sole of the shoe is not very good, but it cannot be done.... it should have been.

Incidentally, the work boots worn by Crowe are not significantly different - though exotic - from the leather shoes in this world without even looking at the soles of the shoes, so neither he nor his surroundings are aware of this problem. The fact that the person does not walk much on the ground with a series of flying magic also delays the exposure of the problem. The inhabitants of Edge Village simply wonder if that is the case in exotic countries. The point was the difference between having "Gentile" information or not.

"I wonder how you carved it"

"You should stick it on a metal plate or something on the sole of your shoe... no, it's going to be heavy for that matter, and your nail tips won't bend and it's going to be hard to walk."

"Oh, taking care of it will be a hassle too. There are more bad things about being a soldier. I don't know what this pattern is for, but it's going to help as a non-slip."

"Well, that's what the Ombrey guy's gonna do."

"You guys... what the hell did you find?"

A young man named Ombrey, who had been sent by the First Battalion additionally, looked stunnedly at the mud mass.

"How's your point of view? Ombrey."

"Definitely a shoe trail. No, I've never seen that. No, it's an unknown shoe trail. What is this engraving? Is it anti-slip, or is it a form of magic?"

"Oh, come on, that's a lot different in anti slip and magic formations."

The two of them didn't think of the possibility of a magic formation at all because they had all the anti-slip things in mind.

"It's an unknown substitute. It's impossible to judge by one shoe trail."

"And then I called you. I'm sending this thing to the battalion right away, but I need you to look into this dungeon with us."

"All right, we're wasting time. Let's get started."

"Hey, it's Ombrey. Who the hell do you think is the lord of those footprints?

"It's just speculation, right? First of all, it would not be any human, elf, or beast man, given what has never been known."

"What are the possibilities that you were developing in secret?

"Why hide it? And why reveal it here? I couldn't feel the will to hide it from the footprints I've seen so far. Besides, sure, that engraving may be useful, but it wouldn't be hard to study it if it left a footprint. If you keep it hidden, it won't fit."

"Go on."

"Oh, the problem is not the technology that was hidden. There are countries or races that have hidden this kind of technology without ever appearing on the stage, and that's the big problem. Bad behavior can change the power map of nations."

"Isn't that technology itself more of a threat than adequate?

"Technology is a stack. I don't think that technology exists alone. A country or a race that can develop that technology is the threat."

What kind of country or race is that? That's what I'm asking. "

"Speculation, huh? If none of the known forces - man, elf, beast man - will remain..."

"The Demon Clan?

"I don't know if the Demons have a habit of wearing shoes. I simply don't have any other species in mind. Including being an unknown species, we'll just call them demons."

The three reached the deepest part of the old "Morrow's Dungeon" as they spoke.

"Right here. I found those footprints here."

"I see that this is the only place where water accumulates and becomes muddy. So this is the only place with a clean footprint? You only got one footprint?

"Oh, I looked around with caution, but I couldn't find anything else"

"Hmm... the footprints were straight to the bottom."

"Oh, so I just think that this bottom tier was the purpose of the problem."

"The bottom tier of the dungeon. Hey, we have a dungeon core and the market."

"Where was it?

"I don't know. Either way, you had it when that brave man crusaded this place."

"You checked?

"Ah? No, but how insane of a dungeon crusade to leave the dungeon core alone, right?

"Look closely. There are signs of a collapsed ceiling. Hey, didn't the dungeon collapse when you crusaded?

"Wait, then..."

"You mean the brave man returned without taking the dungeon core?

"You'll need to make sure."
