## Chapter 1061 – Ancient Beings

I navigate the maze-like underground waterway, guided by Andro’s vibrations. I’m not speeding along like before. I don’t know where a proper signal might come from.

“Hey. Is this the right way?”

ㅡWoooong.

Despite my question, he only vibrates, saying nothing more. I know very well that this bastard’s power is in a very unstable state.

This… should I develop him somehow to make use of him?

For now, imprisoning him in Vygale has made the sword’s performance even stronger. If I keep refining the imprisoned power while awakening his ego like this, Vygale will definitely become an even more ridiculously powerful sword.

It could truly become a Fusion Neo-Confucian Demonic Heavenly Sword worthy of a Heavenly Demon.

But awakening his ego is essentially the same as completely resurrecting him. If an ego becomes embedded in this sword in the first place, many inconvenient things will arise… Isn’t there a way to remove the ego and extract only the knowledge and power?

Honestly, that’s what I want.

I can’t trust this Great Demon bastard in the first place.

Anyway, let’s worry about that later.
It’s a bit easier since I can communicate with him for now.

“Don’t just vibrate, answer me, you Andro bastard.”

ㅡWoooong.

“Crazy vibrator.”

I also wonder what would happen if this vibration were to stop in the middle, but for now, just finding out that there’s something in this underground waterway is a huge gain.

If Andro is reacting like this, there must be something.

It’s definitely a suspicious facility.

Even if it’s an underground waterway covering the city, there’s no reason for it to be this big. Maybe the upper floors are normal waterway facilities. But what about this place below? It’s clearly built for a different purpose.

I speculate that this is a structure from the pre-Idol War era, and it was recycled when Isvant was built. It must have been some kind of dungeon-like building. I should ask the Young Lady about this when I’m invited to the banquet next time. The Young Lady would know.

Good.

This is enough.

Even if I can’t find anything today, I can bring Hilde next time. Hilde is good at sensing these things too… Of course, it might be a different kind of power, so Andro senses it but Hilde might not.

Well, that could be the case.

But there’s no need to think about that right now.

Let’s just focus on this.

ㅡWoooong.

Occasionally.

There were times when the vibration stopped when I turned. So, if I turned around and went the other way, it would start vibrating again. It seems like it only vibrates when I move in the right direction. It would be easier if he just guided me with words.

What a useless bastard.

“Hmm.”

I had been memorizing the maze-like paths all the way here. The 3D map of this underground facility is unfolding in my mind.

This is really simple for me, with my superhuman senses. It’s only natural for a strong person like me.

Looking at the distance roughly, it seems like it becomes an inverted cone shape as I go down… It’s a bit difficult.

How far down have I gone?

I finally arrived at the lowest floor.

ㅡSwaaaaaa.

Underground water was flowing intensely from below the stairs.

Underground water at this depth… and a considerable amount is flowing.

“Hey. Is this the right place?”

I asked Andro immediately.

ㅡ….

Of course, there was no answer.

“You fucking bastard, talk.”

ㅡ…

There’s no vibration anymore.

What a frustrating bastard.

I can’t figure out the direction from here.
He’s useful, but not that useful.

ㅡSwaaaaaa.

But surely there’s nothing in that water, right?

It’s possible that something very secretive is buried under the flowing underground water. But I don’t think I can do anything about that. If that’s the case, I’ll have to call people.

I immediately turned around and went up one floor.

“Ugh.”

And sat down.

“Fucking hell, what is that strange energy?”

ㅡWoooong…

Weak vibration.

There was no reaction below, but it’s vibrating again since I came up.

Does that mean the energy is felt near here?

Honestly, I’ve been slaughtering demons diligently over the past few days, so I’ve become able to sense their energy to some extent, but it’s not as developed as Hilde’s. I have no choice but to rely on this bastard now.

“I should have brought something to eat. You Andro bastard.”

I should have brought something if I knew the exploration would be this long.

After resting for a while, I got up again and looked at the paths I had passed. I checked and marked all the times when Andro didn’t vibrate and when he did. After finishing the work, I went up to the upper floor and did it again.

ㅡ…

After going up a total of two floors while checking like that, Andro’s reaction completely stopped.

He was vibrating right below.

“So, this place is completely irrelevant. And that strange energy is felt on the two floors right below?”

And the lowest floor where the underground water flows is also irrelevant.

ㅡ…

Complete silence.

It was perfect silence.
I roughly figured out the clue with this.

It was the 15th underground floor that he woke up from his dormant state and complained about feeling something. It’s the 14th floor now.

The 17th underground floor was the place where the water flows.

In the end, the area between the 15th and 16th floors that I just investigated is suspicious, but I was about to stop here and go up to do it again tomorrow when I went down to the 15th floor again.

And.

“Kieeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeek!!!!!!”

I screamed with all my might.

If there’s something here. No. If there’s anyone, they will definitely hear this sound and react. It was already a locked floor. There’s no way anyone would be there, but if there is, that bastard knows something.

At least he’s a heretic or someone equivalent.

“…”

No reaction?

Then let’s go to the place where I marked the location earlier.

“Fuck.”

When I arrived at the marked place, Andro didn’t react. I tried shaking him, swinging him around, yelling at him, and flicking him with my finger, but he didn’t wake up again. Is his power exhausted now?

Anyway, it’s here.

The place I marked every time Andro vibrated is right here. I recalled the 3D map in my head and connected the points where he vibrated with lines.

“…”

Area.

A square area appeared.

And the place where I’m standing is right in front of that square area.

“Could it be?”

Is there something inside this wall?

“Damn it. If that bastard had just told me instead of vibrating, I would have found it sooner.”

Because it was blocked by the wall, I couldn’t perfectly pinpoint the location even though Vygale was vibrating.

That’s why he was vibrating every time I went around this wall.

Anyway, after roughly circling around and pinpointing the location, I was able to figure out very well that there was some kind of secret space behind this wall. In other words, Andro was going crazy, saying it was right here every time I passed right next to this specific section.

“…”

I grabbed Vygale in my left hand and tapped the wall with my right hand.

ㅡTok, tok.

Listening to the sound, it didn’t seem like a completely thick pillar.

ㅡTok, tok.
ㅡTok, tok.
ㅡTok, tok.

So, I went around the wall, checking the sound and finding the pillars.

I’m going to break through that wall and go inside from now on. But if I cut down the pillars, there’s a risk that this facility will collapse. If a facility reaching the 17th underground floor collapses here, even I would be in great danger.

Heavenly Demon Kim Kat is the safest Heavenly Demon.

Anyway, that’s why I have to find only the thin walls and touch only them.

Since there’s a secret space inside, it won’t collapse just because I cut out some thin walls. As long as I don’t touch the pillars.

“I’m screwed.”

So, I went around, tapping the wall, identified the locations of all the pillars, and stood in front of the thinnest wall I found by sound.

This should be fine.

In that state, I pointed the sword at the wall.

ㅡTsujujut.

Refined sword energy.

Extremely pure energy gushes out, coating the blade of Vygale. I don’t need sword flames to cut the wall. Let’s cut out only enough for me to pass through, so that there’s as little damage as possible. It’s as easy as killing the murder robbers.

“Oh.”

Wow, but damn it.

The feeling of using sword energy is on a completely different level than before. Whether it’s because my skills have improved or because Vygale has become such a good sword, it’s showing mana efficiency that can’t even be compared to the old days.

ㅡPuk.

While thinking that, I pushed the sword inside.

The blade of Vygale, wrapped in sword energy, went smoothly inside without any resistance, as if stabbing tofu with a knife.

Since it’s definitely a thin wall, I immediately pierced through the wall and reached the empty space. If it’s a wall of this thickness, there’s no risk of collapse even if I cut it all down.

ㅡSsuk.

I drew Vygale down after stabbing it.
Moved to the right.
Drew the blade up again.

Finally, moved to the left and cut it into a square.

I cut the wall itself into a square.

After finishing the work, I immediately pulled out the sword.

And.

“Heavenly Demon Splitting Palm.”

ㅡTuk.

I placed my palm on the center of the cut-out wall and pushed.

ㅡSreuk.

The wall slid without any resistance and fell backward.

ㅡHwiwoo.
ㅡKuwang!

The wall, cut into a square, fell straight inside and made a crashing sound. As expected. It was a secret space using two floors at once. It was a secret space luxuriously using both the 15th and 16th underground floors.

I don’t know why there’s such a space, but if it’s made like this, it’s obvious that it won’t be discovered.

Even though this waterway is so deep that it looks suspicious, it’s just an underground waterway unless you know about the existence of something like this.

Even if it’s suspicious, no one would break the wall like this unless they felt something.

So, this space was preserved.

Probably for a very long time.

It has been preserved like this since it was built.

I found this place purely because Andro told me. If it were me before killing Andromalius, I would have just scouted around and gone back. I would have come with Hilde, wondering if there was anything suspicious. If there was anything, I would have looked for more, and if there wasn’t, I would have lost interest.

Is there anyone who knows about the existence of this space?

Since it’s the underground waterway of Isvant, the Duke or the Young Lady should know… Of course, they might not know. It’s an old building, and they can hide it as much as they want. It’s possible that the information was lost in the handover process.

“Oh, fuck.”

Mr. Merman.

Could it be that Mr. Merman, the manager of this waterway… does he know about this? I have to ask him about that next time.

Why did they create such a secret space? Even making such an abnormally large waterway to avoid suspicion.

Of course, the purpose of having something like this is to hide something.

But is that related to the Lich bastard?
Did the heretics target this place?

I don’t really know.

“…”

Whatever it is, I stood in front of the wall I created.
I’ll know if I check with my own eyes.

“Fucking bastards.”

The cut surface is so clean that not a single piece falls off first. There’s nothing dangerous. There’s absolutely no chance of it collapsing.

ㅡ…

The inside was very dark.

I immediately took off the necklace-shaped artifact, held it in my hand, reached inside, and lit up the interior.

ㅡSaaaaa.

It’s quiet.

“….It’s big.”

It’s a fairly large space.

It’s wide, and it’s tall because it uses two floors.

But it’s definitely not a space so big that it puts a burden on the facility. Anyway, since I already calculated the height after hearing the sound of the wall falling, I jumped inside without hesitation.

There’s almost nothing I can’t do now. Andromalius, that fucking bastard, died after fighting me, so what am I afraid of?

ㅡHwiik.

At the same time as falling, I felt a light floating sensation and quickly looked inside. This secret space was a rectangular pillar-shaped space.

Thanks to the artifact, it was bright enough to grasp the structure.

ㅡKuoong.

I landed softly right away.

Next to where I landed, pieces of the split wall were scattered. Good. There didn’t seem to be any living organisms inside, and I didn’t feel any, but there was something.

ㅡAn empty space.

In the center of that, some kind of structures were placed.

“Hehehe, I don’t know who the fuck you are, but you can’t fool the eyes of Heavenly Demon Detective Kim Kat.”

Let’s take a look at that.
