## Chapter 1351 – Post-War Preparations

The busy days passed by.

My girls spent their time focused on personal training and skill development, while I busied myself with destructive acts.

“Celestial Fiend Obliteration Jade.”

ㅡThwa-ka-ka-ka-kwaang!

As the Celestial Fiend Obliteration Jade fell, the terrain around the fortress transformed. Mountains crumbled and rocks vanished. I was engrossed in reshaping the rugged landscape to my liking.

“Celestial Fiend Overlord’s Stomp.”

Being a Celestial Fiend was like being a superhuman construction worker.

ㅡKoo-goo-goo-goo-goo!!!

With each Celestial Fiend Overlord’s Stomp, the ground flattened. I never imagined I’d be leveling land with martial arts, but it was surprisingly perfect.

ㅡCrunch!
ㅡCrush!

Stones, unable to withstand my power, shattered into pieces. What remained was a completely flat plain, literally fit to be used as farmland.

“Perfect.”

This region had a lot of rugged terrain because the country was full of mountains. I was turning them into plains. Mountainous areas weren’t particularly useful.

“I’m practically Kim Kat-tro, the construction Celestial Fiend.”

Taking off my hard hat, I wiped my forehead with a towel I had draped over my shoulder.

“Refreshing.”

Normally, I’d wear an ice scarf, but my body had transcended the concept of temperature. It didn’t really matter what I wore.

ㅡGlug, glug.

I opened my canteen, gulped down the water, tossed it aside, and resumed my work.

“Ahhh.”

I had a lot of work ahead of me. I was planning to build a grand canal. And of course, planned cities and roads everywhere. Building infrastructure like that of modern Earth. It seemed absurd, but if I put my power to use, and combined it with the technological prowess of the demons, it wouldn’t be difficult.

Anyway, to quickly finish the groundwork, I had no choice but to use my superhuman strength. The demons had wrecked the land, but with my intervention, it would just become a plain.

I should do this work for a bit, then go to Isvant.
And visit my in-laws.

“Kat-tro! You’re burning the candle at both ends!”

As I was absorbed in my work, Hilde flew over, flapping her wings and shouting.

“Already?”

Had time already passed?

“Yes! It seems the people you called have arrived!”

Ah. Guests had arrived.

“Those guys are later than I expected.”
“You’re just fast, Kat-tro. Anyway, they saw me coming from over there, so they’ll be here soon.”
“Good. Then I guess I’ll stop working here. Still, now that they’re here, it’d be faster for us to go see them than to wait. Lead the way.”
“Understood!”

ㅡWhoosh!

I flew after Hilde. As we flew, a procession of carriages came into view from the other side.

“Kat-tro! It’s them!”
“Yeah, I see them.”

They were the experts I had called before.

Technicians from various fields, easily recruited through Kadia’s connections. I might be a transcendent, but that didn’t mean I had extensive civil engineering knowledge, so I planned to entrust the work to them.

But these guys were a bit late.

Well, it wasn’t like they could just teleport here with a phone call.

ㅡThud!

I landed in a suitable spot.

“Ugh… Oh!”
“It’s, it’s the Hero!”
“F-f-f-from the sky…!”

The procession stopped, and its members stared at me in astonishment.

The scale was quite large. Not only technicians and experts, but also laborers seemed to have been brought from around the area. Judging by the number of carriages, it seemed they were planning to start work in earnest.

“Welcome. Are you the technical experts?”
“Y-yes! Hero!”
“Oh, God!”

It seemed so.

I watched them kneel and bow for a moment, then raised them up when the time was right.

“You’ve come a long way, there’s no need to bow for so long. Rise.”
“Thank you!”
“So… first. I’d like to hear some introductions.”
“Understood! Here, please accept this list.”
“I will.”

ㅡRustle.

I received the list and checked it.

“Oh.”

They were experts in their respective fields.

Not only technicians, but also a number of mages were included. Roughly categorizing their professions, they were:

ㅡMaster Romelas of the Karga Kingdom General Construction Guild.
ㅡSoil expert Kuon Darville.
ㅡCanal design expert.
ㅡUrban planning expert Bellepol Ramius.
ㅡAqueduct architect.

And many other civil engineering experts.

According to Kadia’s explanation, they had gathered as many renowned construction and civil engineering experts as they could. Most of the cities had been destroyed, so they were busy, but volunteers had flocked to them like bees to honey, just because I had requested it.

I had asked Kadia for this favor last time, and finally today they had arrived in the area where my fortress was located.

Many of them were from noble families, but most were commoner technicians.

Whatever the case, I could put them to work starting today.

“Good. So many experts from various fields have gathered. Very reliable. There’s nothing you all can’t build.”

As I said that, the people looked moved for a moment.

“O-of course! Hero! There is no structure we cannot build! About half of us are currently active in the capital! We have extensive experience in high-rise building construction and repair, as well as aqueduct maintenance!!!”
“Oh. Is that so.”

He shouted in an emotional tone, as if he was very pleased to hear my praise. But it was only natural. The name of this superhuman hero carried that much weight. Anyone would rejoice at being recognized by me.

“Yes! And I once directed the renovation of the Brass Celestial Angel Cathedral!”
“Oh! That’s very reliable! It must have been quite a complicated job!”
“It wasn’t that difficult for us!”

He boasted about having skills in maintaining the capital’s sewer system, and there was also a dam construction expert.

“I can entrust it to you. Yes. If there are experts in combat, war, swords, and destruction, then there must also be experts in construction like you. What’s your name?”
“I am Romelas, the master of the Construction Guild!”
“Oh! You were the master.”

ㅡGrasp.

As I reached out my hand to shake his, he burst into tears.

“Kuh…! What an honor!”

Seeing an old man with white hair so moved made me feel good too.

“Hehehe, is it an honor to shake hands with me?”
“Yes! How could it not be an honor! I won’t wash my hands for a week starting today!!!”

What the hell is wrong with this guy?

“That’s a bit much.”

Am I some kind of idol…? No. Strictly speaking, I’m half an idol myself. Idol Celestial Fiend Kim Kat-tro dances really well and sings incredibly well. Plus, I’m young and beautiful, so there’s no other way to describe me other than as an idol.

“Anyway. This is my small gift. Please accept it gratefully.”

ㅡScatter.

I immediately unleashed my power and showered them with heart particles on a wide scale. I had to shower these talented experts with likes and recommendations.

“Oh! Oh! Oh!”
“Oooooooooh!”
“Kyaaaaaaaa!”

People reached out their hands towards my hearts and rejoiced.

“This, this is the Hero’s blessing…!”
“It has a mood-boosting effect. Anyway. I’d like to talk while moving.”
“Understood!”

And so, I moved along with the procession.

The master of the Construction Guild explained this and that to me as we moved. Soon, we arrived at our destination.

ㅡSwoosh.

Beyond the forest zone, what was revealed was…

“T-that’s the demons’ aerial fortress…!”

A fortress stood tall in the middle of the plain. A small garden was built around it. Of course, I had leveled the area around it. So it felt like a palace standing alone right on the horizon. With a vast plain as the background.

But was this the first time they’d seen an aerial fortress?
They must have seen it when they were in the capital, right?

“Are you fascinated by the fortress?”
“Y-yes… I’ve only seen… the bottom of it, so…”
“Ah. You were looking up, so that makes sense.”
“It’s truly an incredible sight…!! That something like that could float!!!”

As expected of an architect, his eyes were burning.

Anyway, they shared their opinions among themselves.

“But what’s with this strange terrain? How is there such a flat area here? It’s a bit strange, isn’t it? The map doesn’t match.”
“Um… I don’t know why. Just a moment. I think we need to investigate.”
“And the ground is too flat.”

They didn’t know I had leveled the ground yet.

“Construction Master. This is my request. Read it.”
“Ah, yes.”

I handed him the document I had prepared. He received the document and read it very carefully in front of me.

“Hmm… You’re planning to build a large city centered around this fortress. And a planned city-style one at that.”

He said without any change in expression.

“Something like that.”
“And supply the large city with… sewer facilities? The entire city, you mean?”
“Is that not possible?”
“It’s theoretically possible… but there’s probably no one in this world who has ever built sewer facilities capable of handling an entire large city.”

That was true.

There was no one who had experience building water supply facilities capable of handling an entire large city. This was a natural reaction to something that was obvious.

“Then let’s skip that for now. I’m also planning to build a grand canal in this area. And lay out roads all over.”
“…”

At those words, the Construction Master closed his mouth for a moment.

“Hero. So, to summarize, you want a planned large city with complete sewage and… water supply facilities. A grand canal. And well-maintained roads.”

Then he said calmly.

“That’s correct. Is it technically impossible?”
“Ah, no… it’s not impossible. It’s all theoretically possible. And there’s no architect who doesn’t dream of building such a ridiculous scale, a perfect city.”

A ridiculous scale.

“All architects dream of such a city. Perfect sewer facilities… waste disposal facilities. And giant buildings that are dozens of stories high… and well-maintained roads.”

Completely modern facilities.

But from the perspective of people in this world, it would be a dreamlike technology. Still, to be able to dream of such a world. As expected of someone who makes things, he seemed to have a rich imagination.

“So, there’s the theory, but Hero. Building it is not an easy task. Literally unimaginable costs and manpower. And a time frame that would easily exceed ten years.”

He continued, pointing out each point.

“Just the grand canal alone. Digging up hundreds, thousands of kilometers of land, and clearing the mountains in the path, is an incredibly difficult task…”

The Construction Master seemed to think that I was demanding something absurd because I wasn’t an expert in construction. But since I was a Hero, he was trying to explain as clearly as possible that it was impossible.

Of course, I knew all that.

“I know. I know it’s difficult. Do you think I don’t know that?”
“T-then…?”
“It’s easier to show than to tell. Just a moment. Watch.”
“What… Ah!”

ㅡWhoosh!

I flew straight up.

“Kat-tro? What did you talk about?”
“I talked about construction. I’m going to show them directly.”
“Yes! Show them Kat-tro’s power!”

Hilde, who had been waiting in the sky, cheered me on.

I searched for a suitable spot.

“Celestial Fiend Obliteration Jade.”

I unleashed the Celestial Fiend Obliteration Jade and threw it.

ㅡWhoosh!

The sphere, which fell like a meteor, eventually…

ㅡThwa-ka-ka-ka-ka-ka-ka-ka-kwaang!!!

Collided with the ground, creating a crater with a width and depth of tens of meters each. A huge hole was blown in the ground. Very cleanly and quickly.

“Kyaa! As expected of Kat-tro! Such powerful strength!”
“Hehehe, this is just like breathing.”
“So cool!”

Incredible destructive power.

But in reality, the power I just used was so insignificant that it wouldn’t be an exaggeration to say it was the amount of power it took to breathe.

ㅡKoo-goo-goo-goo-goo-goong!!!

Anyway, I did a few more demonstrations like that.

And landed back where I was earlier.

“…”
“…”
“…”

Everyone was staring at the results of the physical phenomenon I had caused with their mouths open.

“What you just saw was just me taking a breath. If I wanted to, I could unleash something even worse hundreds or thousands of times. And I could repeat that for months.”

Construction Celestial Fiend Kim Kat-tro.

Is an avatar of destruction who never tires.

“Changing the groundwork and terrain is very simple for me. Do you still think that plan is unrealistic?”

ㅡThud.

It was the moment I put my hand on the Construction Master’s shoulder.

“…Huh? Ah?! Aaaaaah!!!”

Then he was startled and had a fit… What?

“What’s wrong? What’s wrong with you?”

I asked in confusion.

“No! For a moment, it was so realistic that I thought the large city was really in front of me! Wow! Everyone! Can’t we do it with this much power!”
“Oooooooooh!!!”
“Kyaaaaaaaaaaaaaaaaaaaaaa!”

As he said that with a straight face, the technicians cheered.

“Hehehe, you’re good at joking.”
“This is revolutionary power!!!!!! Unbelievable power!!!! If we have such destructive technology, then building such a large city is by no means a dream…!!!”
