We had to hurry, save food on the rope, do lanterns, and prepare what we needed to leave.

"Please secure your body to the chair as we will fly"

"Oh, I see."

Everyone rushed to their seats and fastened their belts. Anticipating the approximation, again, when I took confirmation, I surfaced the Sirius because there seemed to be no problem.

"Marquis Broderick, may I ask for directions?

"Okay. Then first - you can see it from here, fly for the entrance to that pit. The problem is, it's an old mine. If we go over that mountain...... I was wondering if we could see a settlement. Near there."

"Okay."

Put your hands on the crystal sphere and manipulate the magic props. The Sirius gradually accelerates. Take in the air and erupt rearward. The moment I ignited the fire magic - I had the feeling that my body would be pushed into my seat by acceleration. The view flows backwards at high speed.

"Oh...?

Malcolm leaked a bewildering voice. Probably because I'm unfamiliar with rapid acceleration. Although the faces of the parties that are able to be manoeuvred in the air are flat for the price.

An old mine survey? Say the Marquis is shifting to agriculture… it is still probably one of the important sources of income, and it is necessary to compensate for the loss of production, as well as for the forthcoming conversion of the Marquis to agriculture.

Cross one mountain so as to penetrate the shortest distance as it is, and find a settlement in the mountains and several mine entrances. I saw a crowd gathering at one of its entrances.

"That's it!

Malcolm points to the crystal plate. It's the mine entrance where people gather. Pass once and swirl. It slows down and is located close to the top, descending vertically at a slow speed. Stop at equal heights.

"Grandfather. Excuse me, may I entrust the ship to you?

"Mm-hmm. Let's protect you from being away"

Siegmund old man snorts. Then let's go.

"Here, Marquis!

Leave the ship to Old Siegmund, take Malcolm and descend in Levitation. Those gathered at the entrance to the mine were round their eyes because they boarded on the Sirius, but when they admit to Malcolm's appearance, they gather.

"I got a report of an accident. What's the current situation?

Malcolm asked, an old Dwarf man with splendid eyebrows and mustaches answered one step ahead of those who were gathering.

"The place in question was still in danger of collapse. The investigation team went further from the location in question, and they should be investigating the back of it, so I don't think they're involved... There was a unique shake when the collapse occurred. It was passed down to the settlement, so I got confirmation, and the place in question was falling apart."

I see. That's why I'm trapped, is it? When the crash was discovered, he immediately flew his horse to the Marquis' side.

If you weren't directly involved, chances are you could rescue them. The sooner the rescue is done, the better, but it will take time to get rid of the dirt and sand.

"Can anyone direct the tunnel to where the investigation team is located? It would be preferable to know the circumstances, such as the number of people in the investigation team."

That's what I ask, and the old Dwarf who was out front snorts.

"You can do it... Marquis, what about this one, Jen?

"It is revealed in Sir Theodor-Gartner, ambassador of the other world. When I heard there was a crash, he offered to help me rescue him. Yes... you are also involved in building that ship, and you are my benefactor"

"It's also..."

And Dwarf raises one eyebrow and then gives me a compliment.

"Thank you, young magician. If the knowledge of an old bone like Nong helps, I can give you a guide or anything."

"Well, thank you, my name is Theodore"

Respond in a courtesy.

I'm Edgar.

When the old Dwarf calls himself that, he bears a large tsuruhashi that stood nearby. Mithrilled silver tsurhashi. Around being treated lightly with a small body, it would still mean Dwarf. He hung a lantern on his waist and held a birdcage with a little bird in his other hand.

"Ignis can take him. Will he?

Ask Edgar and he shakes his neck to the side.

"Some places don't fit in that physique."

... what choice do I have? Let's have everyone's escort turn around outside.

"So... communication with the outside is a communications machine,"

I turn to Malcolm and Princess Stephania and Princess Adriana and say: Malcolm and the others will be leaving messages with Alfred, Valentina and Charlotte. Floria on Tefra. Then there's the face of the Knights of Demons, the escort, and non-combatants like Justia and Dominic.

"Me and Adriana can use some healing magic, though. What if..."

"Yes, it is also possible to fly to Marquis territory with metastatic magic. If this hand isn't enough, it would be helpful if you could take the Sirius back to Marquis."

"Okay."

"Well... let's go"

Turn Grace's curse into a state of liberation and lead Edgar through the magical lights to the back of the pit. As the trees were put together and proceeded through the arched reinforced inlet, the light of the sun outside soon ceased to reach either, and the reliance was only on the magical lights. So once you switch to the magic of dark vision, wrap around the wind walls.

"Ooh...... Is it dark vision magic?"

"Yes, it will continue to work for the time being. I'll call you back at my leisure before I run out."

"What about this, the magic of the wind?

Illumhilt asks.

"Unlike the labyrinth, there's another problem with the pit. There's no air, or worse, a place full of poison. Sometimes when you go to a place like that without realizing it, you lose your mind and die just like that. So we need to prevent that. So is the birdcage bird in Mr. Edgar's hand. Because I'm more sensitive to such changes than humans."

"You're familiar with it. Build walls with the wind, as long as you're comfortable."

Laughs as Edgar was impressed. Keep them all together and move on to the back. In a humid, chilling air pit. The only thing that sounds is our footsteps.

There are several mined horizontal holes, but Edgar's footsteps are not lost. It leads me to move on to a familiar place.

"This pit was dug by Nong's father when he was active, and it was where Nong also worked. We know where to turn and where to go. Fortunately, some of them used to be lounges. They carry water, food, and tools in there, so I think it will last a few days even if they're trapped."

Hmm. That's good information. That's why he needed manpower that could exclude dirt and sand while reducing the risk of collapse.

"... I see. You do have a high chance of survival. I heard it was an old mine."

"Where mining was becoming low, we found a wealth of minerals from the mountains next door. The mining was abandoned when it moved there… The amount of mining has been decreasing everywhere in recent times, depending on whether this pit could still be used if it was reused, and they suggested to the Marquis that they hire adventurers to investigate it."

"Adventurer?

Sometimes demons live in old pits.

"Demons......? Perhaps we should assume that we will fight."

Grace says.

"Right. A rescuer or a demon? To properly identify and then act."

"Okay."

Ashley and Mallane nod.

"Even here, I'll let you know as soon as I sense an anomaly"

and Sheila and Illumhilt. We haven't decided that there will be demons, but let's go with caution.

Every time he comes around the corner, Rosemary takes the flask out of his bag and drips glowing paint down the road. You look pretty bright when you're using dark vision magic.

"Is that... insurance in case of detachment?

"Right. Just in case. I don't really use it in the labyrinth."

"It's handy."

Even in the event of a detachment from Edgar or Claudia, if you mark the paint, you will be able to return to the entrance. Because it's glowing, I can see the landmark even if the magic of dark vision has expired. Besides, if you go around the corner, there are landmarks if you're on the right track, so it's easy to go back.

Each of them has a comms machine, so you can contact them immediately even if they are detached... but it's huge that they have the means to come home alone.

"I... will always be able to use metastatic magic"

"Yeah, please. Destination in Marquis Territory."

We don't talk about double shipwrecks. I can handle a sudden collapse as long as I'm ready for metastatic magic.

Inside the pit is quite complicated, but gradually fewer sidewalks have been made. Apparently, you're heading downstairs.

Eventually... we get to the scene of the accident. They collapsed from the ceiling, and I see a large rock completely blocking the road. There are also cracks running on the ceiling - there is certainly a risk of collapse.

"Again... this is beyond our control"

says Edgar.

"I use magic, so - could you stay back a little?

"Okay."

Ask everyone to take a little distance.

"Serafina is... not home, so you don't know how strong it is?

"It's not home, but maybe I can tell a little"

"The fairy brings good luck to her family and informs her of her misfortune."

And, Claudia.... Hmm. Do you know the structural hazards and weaknesses because you feel the danger of your landlord?

"Right. So, can you tell me where it seems particularly dangerous?

"Ugh. First of all... that's probably the scariest part."

First the ceiling in front. Use levitation indiscriminately toward the top while deploying a shield overhead to prevent rockfall.

"I want a pillar in this heap"

Copy that.

Assemble the golem on the material with the rolling stone, supporting the potentially dangerous area from the bottom and magically reinforcing the structure. Check with the serafina for safety confirmation at each end of the process.

Reinforcement when supporting dangerous places in order. Turn the collapsed dirt and sand from top to golem and head back into the aisle to widen the safe area. If I may, I hope the facade of the investigation team does not come out from under the dirt and sand......

Collapsed dirt and sand are used instead of materials to build columns and reinforce them to cover irregularities in floors, walls and ceilings. Sometimes it seems that supporting one place puts pressure on another...... following the Serafina survey and crushing more and more of those places.

There may still be rocks that are likely to fall, so in that case, quietly drop them on the floor with a revitation to avoid the impact of the collapse.

Gradually, the rocky skin is altered, and the rolling stone disappears into a smooth structure. On the other side of the aisle, a small tunnel opens. It will be extended to the extent that people can pass through and further reinforce the ceiling area.

Eventually...... the last dust was excluded and the collapsed part was just finished reinforcing, exhaling. No one has been buried alive. Serafina seemed to still prudently gaze around, but eventually nodded quietly.

"Yeah. It's okay."

"Okay."

"Theodore. Look."

Just a breath away, Sheila examines and says the passage she opened.

"Traces of this, big thing, moving so vigorously"

Sheila analyzes the situation from the state of the pit. This...

"... something came in from over here...?

The direction of travel is the wall. I know the ceiling can no longer withstand the weight and collapse. So what's on the wall, stamped with cracks like something collided? A closer look at where he thought he had collided had some kind of claw marks engraved on him.

"Mr. Edgar. Do you know what these nail marks are?

"Be, Beryl Mall......"

Edgar rounds his eyes.

"What is it, is it?

Grace tilts her neck.

"It's a giant mole that eats minerals. Strong sense of territory...... it is a dangerous demon with nails that also cleave rocks. I didn't expect anything like that to come out."

Beryl Mall............. I've never met him in the labyrinth...

"I also found people's footprints. Spread out, he's running back."

"That's the direction of the rest stop. Didn't you just stand there and cage it because it's a sturdy build?

"What about the mole?

"Don't follow the footprints, go to that hole over there"

... I see. There doesn't seem to be any traces of bleeding or anything like that, and for now, he said he didn't go after him because there was no room left from the mole's patrol route. The investigation team is safe. It's expensive, but there was a troublesome guy. The crash, too, from the circumstances, I guess it's his fault.

"... it's troublesome when Beryl Mall comes back again. Shall I help the investigative team before I encounter them? It seems to have considerable instantaneous power, and I thought it would be dangerous to fight in the pit."

When I told them the policy, they all nodded.
