With me at the forefront, Rue and Dwarf girl Fiftis continue. Pram, Hemperoza, and Larna joined hands and stepped into the "haunted house" in such a way as to fear.

Monoreder and Scarley continue in a standing position that guards the plumbs from left to right.

"The ghost started coming out about the past month ago. It also leaves during the day. I don't see him... sounds and groans... Plus, the vase was repositioned, the painting was uneven... and the dishes made noise, and the whole family got scared and sick."

Unlike the impression the other day, the master of the hall who invited me in, Baron Yale Marn, looked a lot like he was doing it. He keeps sending me glances.

"That's tricky...... I wish I could help."

The inside of the hall is secluded and somewhere shady.

There are about two old maids out there who are not well, but they look tired without a smile.

"... sir. Are you a customer?

"Ah! Sage, that sage is here!

"As, well......!" "One of those heroes!

"I'm sorry, but I'm going to have to look into everything."

Huge staircase in front and ancestral portrait sloppy in the hallway. They are also decorated with weapons and armor, but they are all dusted.

Because of the absence of windows in the front door, it is dark and the air is starving.

Occasionally, I hear a seki from some room, but I guess my family is on the floor.

"... it's kind of a flinch"

"There's a scary sign."

"Larna is hehe, fine de, dace..."

Pram and Hemperoza hold Larna's hand tightly from left to right.

"Well, don't worry! Stay with the sage here. And I can use magic!

"Ooh! You're gonna get rid of Obake with flowers?

"Ugh......!? It hurts a lot to the plum."

A moment of strength also seemed to shrivel quickly.

"The Awkward also feels something... strange"

Lu gives Russia a look of tension. Pin, and raised his cat ear, and began to ask around. Dwarf girl, Fiftis is kneeling on the floor and feeling something.

"Lu, Fiftis, sure... don't hear anything"

- Detect low frequency (...).

- Detect the seismic waves... The source of the earthquake is 10 Merte underground. Fine vibration, persistence.

Tactics began to capture slight variations.

"You see... could you have?

The baron whispers in a dark voice from behind.

Low frequencies are a form of sound, but if you keep bathing, your body becomes unwell. Demons that magically attack their opponents remotely use high frequencies, but in principle they would be similar.

"Baron, did your family also suffer from headaches, dizziness, nausea, etc?

"! You're right, wise man! Again... is it a ghost curse?

- Is it caused by vibrations from underground and the associated low frequencies?

"I also hear voices...... here! Even now!"

Yikes!? and screams from the maids.

You can hear something roaring, humming low in my ear, too.

"Hey, I heard something!?

"You heard the awkward."

"Grey, I'm obnoxious -!?

Plum tacked on my belly with a fierce dash and hid behind my back with the grunge as it was.

- Doh... Doh...

"Baron, do you have a basement!?

"Yes! Turn left down that hallway and the stairs go downstairs, but... nobody's supposed to be here!

"... glasses. I'm directly underneath."

That's what Fiftis said and when he got up, he ran out at the same time as me. Run along with the prams that are left behind too.

Monoreder and Scarlett have them waiting on the spot.

- Doh... duh! Dorloon ♪

The singing voice and vibration of a unique rhythm still sounded familiar.

As soon as I descended the stairs to the basement, my vision was closed to darkness.

Encourage the Phosphorescent Magic (Will O Wisp) one after the other so that everyone who comes later does not fall, floating down the aisle.

Down the stairs, the basement.

Apparently it's a brewery, or some kind of reservoir from the old days. The old cellar, which is not the same age as this hall, continues to the back with the rocks gushing out.

"This way."

"Lord Grey, the awkward too!

I keep going deeper and deeper. Lu lowers himself and continues to be alert to danger.

The basement was at the end of the line at about fifteen mertes, but the voice and vibrating sound grew louder and louder.

Or it's totally the voice of people...... singing.

"Dorrrrrrrrrr! Dorrrrrrrr! Gokigendrilu ♪ '

"... glasses. Over here!"

Fiftis finally found an empty hole at the end of the basement. At the end of the hole where each person can pass, apparently there is even more space.

But if you look closely, from time to time, the blue and white light characteristic of the crystal lamp flickers.

I put phosphorous magic (will-o-whisp) inside the underground space.

"Dwarf pride! Drizzle, drizzle dolphin camtur......?

"... brother...!

"Dri!? That voice... fifteenth sister! Fifi Fifi, Fiftis?

It was the Dwarf boys who lit up behind the space with the light of phosphorescent magic (will-o-wisp).

He's digging rocks with a big two-pronged drill, a magic tool, on both hands.

"... Ninth, brother!

"Doh!? Why are you here? Do you... Sage Dory!?

"Cogmar Ninth, long time no see"

It was unmistakably Dwarf's "hole digging celebrity" with his former enemy, the Eight Treasures (albeit the soul's loose shell), who fought in the desert country of Israel.

"Dorr? This is... that holy sword room. Dorr?

"Oh, definitely"

Dwarf boy, Cogmar Ninth listens to me and circles his eyes. Eyes on blue hair very similar to Fiftis. Tough but muscular and sloppy in shape is Dwarf specific.

When he finds out I was taking care of his sister, Cogmar Ninth bows his head many times to thank him.

Fiftis lost his way into our hall during the battle of Israelis while trying to save his brother, who was possessed by eight treasures.

We were now sitting in the middle of a hole that Cogmar Ninth dug - an artificial underground space - listening to Cogmar Ninth.

It brings up a number of lights of phosphorescent magic (will-o-wisp) and illuminates the space.

Height and width are about three mertes each. Such a space extends like a passage. It's unclear where it's going from, but it's probably an "iron pile gun" firing facility.

There is an artificial cave that stretches on, but just ahead of you, there is an artificial space separate from the hole that Ninth dug, like an underground temple or a large hall. There were clearly heterogeneous "walls" that stood apart from the black rock beds around them.

An artificial "wall" buried on the ground is found to be part of a cylinder that draws a gentle curve. Moreover, it appeared to be made of the same material as Methanostat's "spire".

"The core part of the spire that is visible on the ground, is that it? How far underground is it?

"I don't know if I dig a dollar. Stiff, dollar, no sharpening, dollar."

Apparently Cogmar Ninth tried to sharpen this, but it didn't work.

Pram, Hemperoza, and Larna are concerned about something like a red and black pipe on the ground. I looked it up with search magic (Ggol) and it was a huge underground mite.

"Dorrrrrrrr. It swallows Ora's shredded rock and excretes it back and back...... convenient giant rock worm, Dorr"

"Gyoyee!? Say it fast!

"It's not in the drawings -?

Plum and hemperosa jump and avoid. The blemishes about 20 cm thick Merte extend long and everywhere and you can't see the head or tail.

"Dorr. The task of digging the vertical hole (...) requested by the Kingdom is over. Dorr. But heh, I was worried about the disturbing (...) wall I found while working on it, and I was exploring the dollar!

I see, it was building an iron pile cannon firing facility, and when I noticed it, it was reaching the base part of the spire... I can also snort that Princess Snoovel, who manages the iron pile cannon, has not received a report.

"So, what happened?

"There was a door... Dorr. Whether you touch me or push me, I won't freak you out."

As Cogmar Ninth led me, I saw something like a hexagonal door on some of the walls. But there's nothing without a handle.

The surface of the artificial stone is engraved with something like a tattoo. But you can't even read my translation magic (Yakutus).

"But finally, I found it...!

I couldn't hold back the excitement. When I put my hand on the door-like part...... I heard a tun and a light came up on the shape of the bill.

"Ooh!?

The doors conveyed signs that they were searching for something "me" better. The light gradually increases, but there are no dangerous magical signs of tactical information display (tactics).

And, baku......! And there was a noise, and Zuzu...... and he pushed me out here. Just, like, cutting stone walls from the other side and pushing them this way.

And the stone wall finally opened its mouth.

"This is... ugh!

"Lord Grey! This!?

"Ooh? Are you glowing?

Lu and Plum raise their voices of surprise.

I peek into the dark and explore if even dangerous demons can emerge. But something did shine across the darkness. Something hard metal.

Projects the Enemy Boundary (Circle) inside the Dark Space. This allows us to see what's going on inside with the reflective waves.

The reflected wave of magic thread (MagiWire) was captured again and raised as video in the tactical information display (Techniques).

"Hey, what no!?

There...

Obviously there was a "sword".

There was, though.

The shadow reflected in the tactical information display (technique) does indicate that it is a single sword depicting a loose curve such as that held by the ergonote.

Length is roughly 130 Merte.

Wouldn't that be weird in size?

Try measuring again, definitely 130 merte in length.

- Something like this, even the Giants are forced to decide!

In other words, a "sword" the size of a spire outside is deep underground and sleeps to be buried. It also has a "sword tip" pointing at the sky.

'Ethereal (Fatimart) Silver (Platinum)' that this is passed down to the legendary Holy Sword, Metanostadt!?

I've lost my word, but if I change my mind... it looks like a flying vehicle.

Could this not be a flying sword - an ancient world flight device (...)?

"Oh, my God..."

I was leaking a little groan with surprise.
