Waiting for us in the room was an old, big lizard man.

The back length is one bigger head than mine, and the shape of the head is a complete lizard shape.

The hard scales cover the body surface without blemishes, and the places are pointy as thorns.

If you encountered it in a dungeon very normally, it was a facade that you couldn't help but take an immediate battle stance, but its appearance dressed in thick black robes gave an intelligent atmosphere.

"Oh, you're Luke Whitewolf. I thank you on behalf of my fellow countrymen this time."

The old lizard man (Lizardman) revealed his joy in a low, masculine voice.

The devil tribe, whose appearance is far from human, is difficult to discern gender and complexion by idleness, but both are relatively easy to understand if one hears voices with strange things.

"A certain (if so) is Eversol. I am a councillor on behalf of Lizardman. Well, this is how humans say hello."

The demon clan, named Eversol, has offered a generous right hand.

It took me a little while to realize that I had been asked to shake my hand, but as soon as I realized that I did, I had my right hand out and shook it too.

Garnett looks anxiously at the hands of a lizard man (Lizardman) with hard scales and sharp claws holding my relatively poor hand.

It was my first experience shaking hands with a lizard man (Lizardman), so much so that I gained new insight into whether I was touching him like this.

"The loss of light in the ceiling (sora) was a matter of death and dying for some (if any) others. Anyway, it's a lizard, but it's late. I have (...) ku (...) ri (...) while I can accumulate some heat, but if the night lasted longer than that, it would have been very intolerable."

The species of humans and beasts bring heat to the body naturally, but the species of lizards and crocodiles say they increase their body temperature in the light of the sun.

Otherwise, they can't even move their bodies.

For a lizard man (Lizardman) with a body close to a lizard, a night without dawn would be like a human being trapped in an extremely cold land.

That doesn't mean that humans are better organisms.

Because they do not drain their strength to produce heat, lizardmen (Lizardmans) can live with even a small amount of food compared to humans and beasts.

From that point of view, more than lizards (Lizardmans) are probably tree people (dry ads) with flesh close to plants.

"Well, it's not as if it's enough to repay you, but I'm asking you to answer your questions. Ask me what it is."

"... so let's start..."

Though it was a sudden call, there have always been mountains to ask if I was happy or unhappy.

So I don't get stuck with questions, but rather worry about which one to ask from.

"First of all, in Athlopolis, take this place... can you tell me what you call this dungeon or each hierarchy"

"Hmm, the basic nomenclature is important."

"Unfortunately, the ground naming was a little incomplete. I thought I'd consider adapting it to your calling style."

I can't help it, but naming by humans on the ground was pretty spot on.

At first, only the presence of the labyrinthine part of high difficulty was known, giving it the name of "The Millennium Corridor of Naruto" there.

It was conceived at this stage as the name of the dungeon itself, not the name of a hierarchy of massive dungeons, because the 'Millennial Corridor of Naruto' was thought to be all about the dungeon.

But ahead of us through the labyrinth was the force zone of the army led by Demon King Gandalf.

The name 'Demon King's Castle Area' was given there, and 'The Millennium Corridor of Naruto' changed to the nomenclature of the labyrinth part rather than the whole dungeon, but the name of the entire dungeon that replaces it has yet to be determined.

Further down through the labyrinth that stretches beneath the Castle of the Demon King - in other words, this underground space where we are is also not officially named, even if at the moment it is simply called the 'Deep Realm'.

"Some of them have learned to call the dungeons of the earth the Ark of Elements."

"... of elements, the Ark?

"Uhm. You should think of a box filled with four elements one at a time, layered vertically. That's what some people perceive about the world."

"Four boxes... no way..."

I told Eversol exactly what came to mind.

"The Four Elements of Elemental Magic. The hierarchy we call the" Demon King's Castle Realm "is an underground space with rocky mountains and wilderness on one side… which means it represents the attribute of 'earth'."

"And this hierarchy, as you can see, symbolizes' water '… it is the idea of some (if any) people. I don't know the true meaning of the Creator Alphazur."

Magic is not a specialty, but I buy it in anticipation that major knowledge of the four elements or so will help me with my adventures.

Indeed, if the characteristics of this hierarchy were to be represented in a nutshell, it would still be rich water and green, which I do not believe to be underground.

If you consider that blue and lush plants are a gift of abundant water, the most essential thing is that of water.

"On the ground, the order of the four elements is made from the heavier to the soil, water, wind and fire. If this dungeon is the same, does the deeper realm also have a wind hierarchy and a fire hierarchy?"

"As you can imagine, some of them think so. But the majority of the species living in Athlopolis have long lived in this hierarchy. I don't know anything else."

If Eversol's description is correct, it is information that the Alliance guys are likely to flip and rejoice.

Even me, if I hadn't carried a serious position, I would have eaten a great deal without one or two.

It was a great discovery in the first place when the "Demon King's Castle Realm" was discovered, and to the discovery of this realm, that was the kind of recognition that touched upon the secret abyss of the world.

But even then, it was only a turning point.

In view of the little progress in the exploration of this hierarchy, we can even say that it has not reached a turning point.

While I managed to contain the excitement that gushed inside, I tried to keep my questions calm.

"… So what is the name of each hierarchy?

"I'm sorry if I missed my expectations, but I'm not calling you that elaborate. The place you call the 'Demon King's Castle Realm' is the first tier of the 'Ark of Elements', and this is the second tier... simply this is it"

"I see...... hmm? Is" Demon King Castle Realm "the first tier? What about The Millennial Corridor of Naruto?

"Some of them don't treat the labyrinth as a hierarchy."

Eversol shook his shoulder like a laugh.

As usual, the expression is hard to read, but it's a trick that conveys that he enjoys this conversation too.

"The designation is even simple and lucid. I was told that there is a first labyrinth at the border with the earth, just above this hierarchy there is a second labyrinth, just below there is a third labyrinth… perhaps there is also a fourth labyrinth"

"... have you never been to another hierarchy?

"It would be a lie to say that I have never even tried. When I was younger, I tried to get up the tower leading to the Second Labyrinth, not once or twice. Well, it was common to get scared on the way home."

Now Eversol laughs out loud in plain sight.

I also decided to share my next question as I danced my mind to the new facts that I would constantly discover.
