Until the last time I turned back, nothing in particular went wrong with us, but that speed was slower than last time.

The cause is still mapping.

Yuki struggles badly with the azimuth, but it seems difficult to draw a subtly curved passage.

"One side of the mass is 20 steps, and walking diagonally takes about 28 steps... oh, but it depends on the angle..."

It seems to be mapping with a feeling of about 10 meters a mass, but it seems difficult just to hear the words that are bumping.

Still, I seem to have grasped some sensation from the way in, and I also increased my speed, but still much slower than I normally walk.

At this rate, the range that can be explored is likely to be influenced by Yuki's mapping speed and his patience. I don't think I'd keep it for an hour.

"Doesn't this seem like you need a break quite often?

"Well, it's going to use nerves for mapping, and that would be better."

Watching Yuki scratch her head hard, and when I whisper to Hulka, Hulka nods again too.

It would also be difficult to map alternately with someone.

The stride width is different, and the sensations such as angles do not match again, so it is likely that there will be no integrity.

"I'm here to poke at you, which way do you want to go?

This is where I turned back last time.

If there is a branch, the mapping is necessary, so I turned back, but there is no big difference between the two paths, and there is nothing to guide them.

"You can do whatever you want. I don't have a clue."

Let's go left, then.

"Why?

"Somehow?"

Toya responded to Hulka's words without being able to tolerate her hair, so I asked her why, but she really seemed somehow and for no reason at all.

Well, it's worth worrying about, and there's no reason to just disagree.

We will honestly move in the direction Toya chose.

Abandoned pits are only artificially dug holes, free of unnatural irregularities, and easy to walk.

Although the trend seems to be towards a slope that falls slightly towards the back, its gradient is quite moderate.

"But this pit, there's no pillar, right? Is it okay if I don't support you?

"It feels like I touched the wall, it's pretty stiff, isn't it? But it must have been hard to dig, mostly rocks."

"Is that why a large number of workers were put in? If you get caught guilty and put to heavy labor in this place, you might even know you're undead."

I don't know how much labor it takes to develop this kind of mine, but I've defeated at least 100 undead so far.

Considering those people were forced to work, dig this mine, and die...

I feel a little thin and cold and hold my arms.

"Nao, what's wrong?

Hulka called out to me wondering how I was doing like that.

"No, something, I thought a lot of people died here, kind of."

"Nao, are you scared?"

That's what Yuki says with a teasing grin, but don't you hate it?

I don't think anything in particular is going to happen, but I'm in the mood for people's deaths, like crematories, late-night cemeteries.

"Don't worry, Nao. Because ghosts usually leave here."

"... you did"

It is unclear whether that is an element to be relieved of, but it is certainly a situation where you cannot say 'I am afraid of ghosts' or something like that.

I mean, he's already killed Ghost normally......

"I know how you feel. I'll 'purify' you thoroughly, so you don't care."

"You've already killed a lot of undead, but Nao is also delicate in strange places."

Hulka and Yuki say so lightly, and Natsuki is smiling a little too.

Our women, they're too successful.

- No, even if they say, "Yikes, wow," absolutely, "Yikes! 'I will.

If you think about it that way, it would be a good thing.

"Let's get back to it, the reason there's no pillar to support the ceiling earlier seems to be because there's magic. Seems to follow the dig ahead and cement your surroundings with dirt magic to prevent collapse. Is it like shielding?"

"Then you don't have to worry about collapse."

It is quite a safe method of construction, also employed in modern tunnel construction.

If it's dirt magic, it can harden without a connection, so maybe it's safer here.

"But didn't I tell you that I couldn't gather specialist technicians here, or Diola? Because it was top secret."

"............... you better watch out"

Unhanded construction, no, Zettai.

"Yeah. Nao, if that sounds dangerous, solidify it with dirt magic. I'm busy mapping."

"Copy that. Natsuki, let me know if you have anywhere to be concerned. Because I'll deal with it preventively."

"Okay. I don't want to die buried alive."

"If it's a little something, it looks like we could use dirt magic to get out of here. Still, less danger is better"

Even in modern times, we hear that there are frequent landfill accidents in mines in China, and we won't be too careful.

I also spear through the surrounding walls, checking to see if there is anything brittle.

"There's been some change... a dig trail?

"I wonder"

After walking out of the divide for a while, sometimes, a pit appears that has been dug forward like a side road to the left and right of the road, but its depth is less than 10 meters, illuminated by lights, and you can see a poking hit.

Thankfully I don't have to worry about getting lost, but I'm slightly bored.

"Normally, you wouldn't dig a pit in a complicated shape, would you?

"What about that? Digging after the mineral veins can also be complicated with nature?

"I see, you have that."

The purpose is not to dig the aisle, but to dig out the ore.

And that mineral vein doesn't necessarily run straight.

With that in mind, what Natsuki says makes sense.

Could it be that the first road was slowly curved, for that matter?

"Oh, it looks like it's over."

"... Phew. It's about 800 meters from the divide."

There were no enemies, so the most tired of us would be Yuki, who was doing the mapping.

When she stopped her hand and exhaled, she counted the mass eyes on the map and said so.

"Tired. Are you okay? If it was, I'd rest here? It's just getting a little wider."

The end of the aisle, which was at the end of the line, was dug up to about the size of a little room.

However, to the extent that there are some pieces of wood falling on the ground, I'm not sure if they were used for any purpose.

I had an image of some more trash or something that was going to fall off, but what was it like mining?

"Yeah, I'm fine. Even if I say I'm tired, it's a mental thing, and when I get back, I need mapping."

"Really? Then let's go back."

If Yuki says so, he goes back to the divide without pinching a break in particular, this time to the right road.

Long side roads stretched from left to right on this road, but basically in relation to the main aisle and side roads, it is concise to the extent that even if there is no map, it is not lost.

And about an hour's walk from the first division, the first time I caved in, I had a reaction to [enemy].

"It's skeleton. The distance is about 100 meters forward."

"Good. [Enemy] is valid."

"A little short distance, though."

I am concerned about the enemy range, which is significantly shorter than outdoors, but nevertheless sufficiently necessary in practical terms.

This is quite a reassuring material.

"Sure, if you clear your ears, you'll hear a rattle. What do we do? Does magic keep us warm?

"Right. There's a good chance there 'll be a lot of undead out there, and we'll kill them normally."

If it's a zombie, I'd like it to be "purified," but if it's a few skeletons, there's no hard work.

There are only five skeletons that show up, easily driven out by two avant-gardes and me.

"Will there be more coming out? At the pace we've been at, honestly, I'm free and I can't make any money, okay?

"I don't know about that, but wouldn't it bother you to come by too often? Like when you sleep at night."

"... Indeed. Don't stay."

Toya is right in terms of earnings.

But our purpose is to avoid the heat - for the recovery of the Viscount's family heirloom.

Assuming it fails, there is no penalty, and if it can be successfully recovered, it may be possible to connect with the powerful.

This country still seems to be in a better category, but there still seems to be something like people's rule, so it would be more reassuring to remember.

Honestly, it's easier that way if you don't have to get involved at all.

"Speaking of which, there was magic in dirt magic called Mineral Detection" Seek Earth, "right? Nao, can't you look for Mithril with that?

"I can't. That's because I can't find it without the operator knowing the metal in question"

The magic of Mineral Detection Seek Earth, which is also used when searching for mineral veins, can be totally meaningless if the operator doesn't know what reaction the mineral vein will return.

By analogy, it's like looking for objects with a blindfold and a touch, so if you don't know the shape and touch of the object, you can't possibly find it.

"What about gold, silver, copper?

"Neither can you. The best part is iron, but picking up ore with less content or something, it doesn't make sense, does it?

"If you're poor, then so is that, but not now."

Because of this opportunity, I also tried to use it.

Iron, gold and silver, etc. somehow figured out the reaction, but unfortunately the minerals that could be detected here were not at least as content as riding on a profitability basis.

"Well, it's not realistic to mine it personally, is it?"

"Yes. By the way, the original world seems to have an average gold content of 3 grams per ton of golden mountains, right?

"Oh, seriously?

Natsuki nodded flatly at Toya, who listened back surprised at the content that was lower than he could have imagined.

"Yes, refining one cup of dump car will only give you a few pieces of gold if it's pure gold"

"Wow, that's awesome. That's tough"

The gold coin I usually use in this world is a 'coin containing gold', which has a fairly small gold content, but when I hear the nuts, I can understand that as a matter of course.

If it turns out to be a big gold coin, about half of it seems to include gold, but still whether the cost of production and monetary value match......

I find it difficult to think about digging with manpower, not industrial production, but will the area be covered by magic or alchemy?

"Nao, you can't magically extract directly from the ground, Zumomo, to the feel of it?

"I don't know what to say, Toya. For once," Creative Earth "is the magic, right? When I use it, I fall down!

What happens if you try to collect elements with low content. It has already been experienced when making baths.

- Oh, well. Is it possible to extract in the soil creation "Creative Earth" as long as the ore with a high content is collected? Then don't make refining easier.

Maybe it refines with it in this world.

"Speaking of which, which is rarer than gold, Mithril?

"Mithrill, it would be. Given the volume of distribution. It's not pure gold, but gold is in circulation."

"Wow, is it harder to mine Mithril Ore..."

To Natsuki's answer, Toya turns to face.

If it's more than gold, even if all the previous pits have been packed with misrillic ore, it'll only be a handful if refined?

... Yeah, it's still impossible to recover the misrill ore.

I had a faint expectation that if I did well, I might be able to get Mithril's weapon.

Do you honestly save money and buy it?
