The next morning.

The Earl brought back the knights of his companionship.

By the way, for some reason, they are all cat beasts.

Seeing where the Countess was not supposed to have been with you in Wang Du, have you not yet returned from Yuji Field, or have you had business separate from the Count?

Anyway,

"... why is Reese here?

He couldn't swallow the situation to the sight of his beloved daughter, who was supposed to be in Wang Du, eating breakfast at home for some reason.

(Oh, you don't know that South Fortress is about to be invaded, do you?

"Hmm. That explains it from the concubine."

"Hih, princess... chancellor!?

At a surprisingly retreating age, the Count is about to knock down the candlestick that was standing behind him.

He seemed to notice the Waltz and the others once, but he didn't even seem to notice that Theresa was in there.

"We're talking from the Border Guard. There's 800,000 enemy soldiers on their way here.

"... yes?

After all, as expected, the story of the invasion by Endelusia did not seem to have arrived until the ear of the Count.

So Teresa explains everything she knows.

"Shh, take immediate action..."

To Teresa's words, the Count, who turned pale, raised his voice.

"Ah, Count? I don't think we can beat the South Fortress side no matter how hard we try this time on the boulder, so we'll do something about it. So could you just consolidate the protection of this town?

and voiced, 'You can't protect this town!' And Waltz, who says rude things to the town's patron count.

All they can do is make an evacuation recommendation against a small settlement on the enemy's path, about which a hunter has dispatched soldiers of the decree within yesterday.

When it comes to what the waltzes can ask of them besides consolidating the protection of the town, is it about chores?

But even a boulder waltz couldn't seem to ask you to do the chores.

Meanwhile, the Count also seems to have realized that when he calmed down and thought about it, he didn't know how to fight 800,000 enemy soldiers, and decided to leave it to the Waltz and the others.

"Are you sure?

"Yep. That's why I'm here."

"... okay. Then please."

That being said, the Count has bowed his head toward the waltzes.

If this was another nobleman, it would not have gone so easily because of pride and troublesome fences.

"And, Father... I'm embarrassed."

Some uncomfortable looking hunter for including himself in the object of gratitude.

"No, you should lower it inside you have a head that can be lowered. It doesn't diminish."

The Earl told her so in such a tone as if it were natural.

Of course, it is not normal, for example, for nobles to bow their heads so easily.

"It would help if you didn't care too much..."

(I'm not fighting for South Fortress...)

I wouldn't say waltz.

Instead, speak the truth.

"So, I'd like to make a trap, can I dig a massive hole around this town?

and waltz asking permission for territorial overhaul.

Nevertheless, with the permission of the Speaker (Teresa), most of the impotence would go by, but she still didn't want to get permission because she couldn't disdain the Count, the hunter's parent and acquaintance.

"Oh, I don't mind that... but it would be helpful if you could take care not to destroy fields etc"

"Yeah, of course it is"

That's why I got the Count's permission in two replies.

(Now you can make all the traps you want)

Laughing inside... it's also a waltz that floats something of the evil kind.

Thus, since the beginning of this country, the magnificent O Tagorasui O begins... should have been.

Waltz and the others, who came out of South Fortress after the meal, were walking down the street leading to the southern border with a circle in place as a countermeasure to Altair's attack.

Then he walks about 2 km from town, comes around to where the fields are gone, and stops at Xu (Omoro).

"Well, shall we build a base here?"

Using that word of Waltz as a signal, Catalina and the wise, plus Lucia, activate the urban junction (reserve) brought from the king's capital.

This would prevent even demons from coming into this perimeter (about 5km radius), as opposed to altile attacks.

"After all, it's an underground base. So, Lucia? Can you drill a hole down here about 500 meters deep? Size... in about 10 meters."

"Yeah, okay"

Lucia putting her hands on the ground and exercising earthly magic.

Then, suddenly, a huge hole opened to the ground.

(After all, the output is out of step with the rear)

Unlike the rear, which was full because it digs a few hundred meters in diameter with a bangle equipped, Lucia easily drills the hole as Waltz ordered, even without a bangle (but with a cane).

Seeing Lucia like that, swordsmen and sages were solidifying, but it wouldn't be a matter of concern now either.

"Well, will everyone just wait here for a moment? Because I'm going to expand the horizontal hole now."

"Oh, be careful."

and a hunter who speaks out against the waltz.

"Oh, you can never peek into a hole, can you? Maybe die."

"... oh, careful"

Apparently, the person to watch out for was the other way around.

Hearing the hunter's words, Waltz jumped into Lucia's open hole without getting lost.

Waltz notices an anomaly around a descent of about 200m for a while.

Apparently, the basement is open.

And she saw something real in the basement of South Fortress.

"... uh... big cavity...?

What Waltz saw was a massive build-up of water, a huge space.

It's called an underground lake.

From what I can see from her, it looks like 40% of the lake area and 60% of the land area.

The air was more limp than on the ground, as if in a bell cave or cave.

However, its shape, unlike that of a bell cave, was not like that of a stalactite stretching from the ceiling or the ground, and it had never caved in like a cave, a domed space with a slightly snoring shape.

Dungeons (boss stage in).

If I were to explain it in simple terms, I would run out of that one.

(I never probed the ground, but I didn't think there really was a place like this...)

The height to the ceiling is 300 m, about 500 m to the surface.

The depth and width were highly reflective of the radar and the exact distance could not be measured.

(I wonder if that means creating a weird trap on the surface, if you do poorly, you'll sink and enemy soldiers will fall this far...)

Waltz held his head when he couldn't do what he wanted.

However, Waltz came out.

"Hmm? Wasn't it a long time ago? Are we done yet?

The first person to react to her was the hunter.

"... hey, we got a problem."

When Waltz says' troublesome ', he basically frowns because there's nothing to be busy with, hunters, and his people.

"If you actually come, you'll see. Catalina? I'd like to move, but the anti-metastasis junction, if it moves, it dissipates magic, right?

"Yep. Then I will stop the junction. If it's stopped, it won't dissipate magic in vain."

"Hmm. Then please"

Then Catalina stops the junction.

"So, guys? You might bite your tongue, so be careful, okay?

"Ugh..."

Waltz floated everyone there without question, and slowly descended into the hole earlier.

"That's why..."

"... I see, you mean Mr. Waltz doesn't know why"

"That sort of thing"

Waltz was watching with everyone around him after he unloaded his people underground.

It should be noted that the urban junction has been restarted by Catalina when it reaches the ground, so it will not be inadvertently attacked by Altair.

It is a precautionary measure in case you do not mention the name 'Altair' for the first time, but it is possible that it is still being looked at.

"This is good for a dungeon, right?

Waltz said, pointing to the large cavity and underground lake that spreads in front of him.

"I've never been to one of these places before, but I don't think it's a problem to see it as one of the dungeons"

And the wise man answers.

Catalina next door seems to agree.

What makes it different from a normal dungeon is that there is not a single demon?

Apparently, there was no entrance to enter this space.

"I didn't know this kind of space was under South Fortress."

A hunter who doesn't say 'I didn't think'.

like,

"What do we do? If we keep this up, can't we even make a trap?

Waltz also expressed the concern he had in mind.

"Well... I don't like it when a lot of enemies get in here and the water quality in the South Fortress well changes."

Imagine a blue, clear underground lake clouding, waltz frowning.

As Waltz looks at the underground lake with that in mind, the figure of some passes behind his brain.

"Oh, speaking of which, I forgot about the water dragon"

"... you had some animals like that"

and Tempo, the person who shortened the torso of the water dragon.

"No way, are we moving water dragons to the underground lake here?

To her words, though a little thought, Waltz denies it.

"No, if you release a water dragon here, it'll contaminate the water quality with excrement or something, so that's a pear."

"You agree with that, too. I don't want to drink well water that smells."

Waltz and tempo thinking of intelligent water dragons as if they were pet animals.

"And I'm not sure, but you're mascotting, right? You can't move out of town badly anymore, can you?

For once, my promise to the Count was that after a while the Waltz and the others would recover it.

"I don't know what the hell's going on with me either, so next time, discuss it with my father."

and hunters.

For once, the father (the Count) and I seemed to exchange information in letters, but like the waltzes, we had never seen first-hand what was going on with the water dragon, so we couldn't seem to say anything.

"Well, I hope that's the case."

So the story of derailment returns to the story of setting up a trap.

"... make this space just for us to use, and set traps only on very thin parts of the surface..."

"Isn't that okay?

Or are you willing to decompose the ground so much that there are no more traces?, said the tempo.

"Yeah... as far as I'm concerned, I wanted a high/low difference because I wanted to install a water slider, but that's a bit of a change of plan"

Waltz ran his mouth as if to create an amusement park.

Apparently, he was really willing to decompose the ground.

However, thanks to the existence of the underground lake, it seems frustrated...

"Well, shall we get down to work?"

unexpected (inside?) waltz decided to convince me that it was a cavity discovery, but it saved me time digging lateral holes.

This is how the land around South Fortress will be modified based on this great cavity...
