Two days later.

The weather is rainy.

Temperature 29 degrees.

And 100% humidity.

In other words, the discomfort index is in a kanst state.

... but the town of South Fortress is.

"In the Count's mansion, maybe even a heat pumped air conditioner with an underground heat exchange..."

In a limp and comfortable underground, Waltz shrugged as he picked up breakfast.

The development of the underground was well under way, and there were now tunnels connecting the underground directly to the South Fortress, as well as the installation of LED lights illuminating the entire underground.

That and this would be a major reason why the Count allowed some of the Count's mansion to be used as a workshop by the Waltz and others to shorten the construction period.

Thanks to this, even at this stage, if the Canopes failed to shoot down the airship for the transport of the barracks and the Waltz had the worst that could stop 800,000 soldiers, the prospect of safely evacuating the South Fortress people to the underground lake stood.

By the way, why did Waltz talk about air conditioning?

"Right. With this body, you can enjoy the heat and humidity..."

And, the body was a creature, and the brain groaned disgustingly at the tempo, which was a machine.

"Well, I don't like being hot, I'm the same..."

We both didn't like the heat.

"Air conditioning?"

Lucia sitting next to me, what's that? I'm going to look up at Waltz's face like I said.

"Uh, it's a machine to keep the room cool in summer and warm in winter."

"Hmm... something magical?

"Right. If you don't know how the air conditioning works, it could be magical."

Perhaps even in the modern world, some people who don't understand how it works feel like air conditioning is magical.

(Hmm? Air conditioning...)

Apparently, something flashed in the waltz.

(Problem is power... yeah, let's use that one)

"Uh, sister?

"Oh, I'm sorry. I was just thinking..."

At the same time, waltz how he's putting his hand on his mouth and thinking about something.

"Dear Lucia, When your sister is in this state, she won't be back for a while, so please leave her alone."

"Yeah, okay"

Instant answer, Lucia.

Sounds like the usual.

"That's right, Master Lucia. It's about time your sushi was unraveled, so it would help if you could freeze it again?

That said, tempo to remove frozen Inari sushi and some food from the item box.

It is a fixture for storing food in an item box that does not stop time inside.

"Oh, yeah. I forgot. Thanks for letting me know, Tempo."

And Lucia, who uses ice magic to lower the temperature of food and treat it so it can't be solved.

This is the daily routine of the two.

Speaking of routines,

"Well, before we even start working today, let's go hunting!

... the rain, but it doesn't look like he cared about it at all to the hunter.

"Sister! I'll accompany you!

and Swordsman.

They don't have the concept of a discomfort index or anything like that in them.

... Well, hunting, it's just a battle drill for the South Fortress defense.

By the way, the hunter's task... is still hunting.

The job is to capture demons for use in traps.

In other words, after one hunt each day, he spent the days going out hunting again.

Apparently, his life at the Royal Castle was quite depressing.

"Now, Nicole, let's proceed with the analysis of the kingdom."

Catalina also opened her mouth.

"Oh. Today's the day you want to put your eye on it."

These two continued their analysis of the junction, even away from the Wang capital.

Rather than that, Catalina is in charge of treatment, so she didn't have a job unless someone got hurt.

For this reason, the underground work command post (?), while proceeding with the analysis of the junction, he was dealing with the injured person.

It should be noted that the wise man works as an adjunct to Catalina.

2 I hope the day will come when that effort will be rewarded, but fulfill...

"Shall the concubines come to the Count, then?

"Yes, it's a reconnaissance today."

Teresa and Julia also walked towards the aisle to South Fortress.

Waltz had been entrusted with gathering information.

So their workplace was in the command and transmission room prepared by the Count.

So there were three of us left here.

waltz, lucia, tempo.

In other words, these three are creating a trap that essentially extends around South Fortress.

"So today, we're gonna dig the waterway, right?

"Your sister? Didn't you stop watersliders?... Ha, could it be broken..."

"Excuse me! It's not a waterway for a water slider."

If anything, tempo wants to decide waltz broken for now.

Is it also aimed at the right of control of the whole range of mobile armor?

"How big of an aqueduct do you dig?

"Right... about 20m?

"Hmm. Then it'll be easy."

And it's no big deal, Lucia, like that.

Note that normally it doesn't end that easily.

"Well, shall we go"

... This is how the waltzes began to create their outrageous waterways.

So waltz and lucia who came outside, and tempo.

But somehow, Waltz left them there and flew away somewhere.

Waltz descends to the ground about 2 km from where he grated Lucia and the others.

Around here.

Waltz then spoke toward the tempo (just above Lucia), which was caught in the distance and floating in the sky by the arm of manoeuvring armor.

Of course, using parametric speakers.

'We're ready!

Then...

Dgowwwww!!

A beam about 20 m in diameter flied upright while scraping the ground in the waltz.

It is Lucia's magic particle beam.

(Scared...)

Though it's no problem to hit it directly, it's a situation where Lucia's thick beam looms in front of her with considerable force as she chooses the ground and knocks down the trees.

It's stranger not to be afraid.

But Waltz, frightened but calmly, took the flying beam and converted it into heat and light energy before dissipating it in the direction of the sky.

Thus, within a moment, an aqueduct spanning 2 km in length was completed.

The shredded ground is in such a state that the glass has melted due to high temperatures, and even if the water is flushed, it does not seem likely to break down.

Repeat the task of... three times later, like a square waterway surrounding South Fortress (trench?) was completed.

It should be noted that the journey takes 15 minutes.

"Well, the tunnel's next."

Waltz, who recovered Lucia and the others, came to the corner of the square waterway.

"Lucia? Can you dig a vertical hole about 30m deep and 4m wide here?

"Yeah."

Then Lucia, who exercises earthly magic and finishes digging the hole in an instant.

And the waltzes descend into the holes that were made.

Waltz opened his mouth again after stepping down to the bottom of that hole.

"So next time, can you dig a hole about 4m across? Yeah... I think it would be just fine if you could just go here and shoot me in the beam."

That's what I said, waltz to mark the vertical hole wall.

"It's not dirt magic, so you can't adjust to depth, can you?

"Well, you're gonna be okay"

The point is that if there is enough length to dig, there is no problem if it is too long.

"Well, I'll be there!

Lucia then exercises the same magic particle beam as earlier.

However, the thickness is about 4m.

Dogowo...

Without any resistance, the beam wore through the wall.

"Well, then, next time"

Repeat the task three times as well.

Apparently, the accuracy wasn't bad either, and the tunnel was completed almost directly beneath the waterway.

... Well, as Waltz expected, tunnels have opened up far away, but it would be a range of errors.

It should also be noted that this will take 15 minutes.

... Waltz and the others to complete in half a day the fabrication and placement of waterways, various gimmicks, and piping to draw water from a river that was far away by repeating this task.

When I noticed the area, I could not tell by its appearance, but it was just a tunnel stretched out in the eye shape of a net and a land full of plumbing.

"Um, sister? What are you going to do with this demon modification of South Fortress?

"Huh? Aren't you Pita O Rasui O Chi?

"... have you mismatched your purpose with your means?

"Well, if the results are the same, it's no problem."

To that word of Waltz, 'You're totally rampant...' and a tempo with a shuddering face.

"Sa, next..."

This is how South Fortress is forced to expand its function as a Fortress in half by Waltz.

At noon.

By this time the rain had also stopped and the sun was peering through the gaps in the clouds.

Thanks to this, the temperature was even higher and the discomfort index was breaking its limits, but there was nothing that could be done for Waltz, who could not manipulate the weather.

Well, she had some concerns.

It is something I completely forgot when I said I had discussed with the hunter two days ago.

... What happened to the water dragon?

"Wow!

"High, high!

"Wait, it's my turn"

"These are the children. It's not about fighting."

... was turning into an athletic for the kids.

As far as that look of playing fine, apparently the offense index doesn't matter to the kids either.

"... mascot... rather than being some kind of play tool?

After digging through the tunnel for the coarse plumbing, a water dragon appeared in front of the fountain, wrapped in the eyes of Waltz, who came back to the street village in South Fortress to buy lunch.

When the waltz snaps, the water dragon,

"No? Whoa... this is the Lord. Long time no see!

And as I wrapped my arms around it, I happily thanked him just for his head.

"I'm sorry, but there are children, so even as..."

"Yeah, I don't mind at all. I mean, how did this happen?

Then the water dragon looks up at the sky with a distant gaze, as if it recalls a long time ago.

"... it was only when we came to this town that Non lived quietly..."

Some sad water dragon.

But it was going to be a long story.

"I mean, when I realized I was surrounded by kids, and I was entrusted with nursing."

waltz to shorten as much as possible.

"... remains, well, that's the thing"

Looks like it was a hit.

"Can you stay like this?

In other words, does it have no problem with the kind of life that keeps taking care of the children?

"... I rarely dream about when I was freely swimming in the Great Sea Plains, but I'm going to understand that there's no way to do this at the moment. Besides, it doesn't mean I don't like children. I'm still not complaining."

And a water dragon who lays his eyes down and tells him, saying something like an old hideout somewhere.

Waltz said to such a water dragon.

"Speaking of which, if you don't mention the name Altair outside the town's boundaries, it doesn't look like they'll attack you for now, does it?

"Is that true?

Light returns to the eyes of the water dragon.

"Yep. I tried experimenting on you a few days... didn't you hear me this far?

"... I do think I heard words cursing Master Altair... but I thought it was empty ears"

After all, Lucia's voice seemed to be heard quite extensively.

"That's why I'm going to be able to live outside if I just live my life normally. But..."

In the first place, he can live undisturbed because it is in a South Fortress town where mysterious water (mana) (?) springs up.

If you were to say you were leaving this town, as you did when you came to town, if you didn't continue to receive Catalina's life-extension treatment or move into a large tank, you would be dried up before you reached the waterfront.

(When the waterways and canals are complete, some hands swim and travel there...)

Waltz thinking about the waterways created for the trap, and the artificial rivers currently being created, thinking about whether something can be done for the water dragon.

"Once this battle is over, I'll think about your freedom."

"... take care and thank you"

The water dragon bowed his head deeply to Waltz's words.

It goes without saying that the kids who were watching that were mistaken for Waltz as a great guy.
