Having spent the night at the lodging provided by the mayor, we were stepping into the tunnel the next day.

Only active mines are well supported by pillars, etc., and the risk of collapse seems to be low. However, since the mine is closed, there is no light, and only Tania's lantern illuminates the passage.

Though the light intensity is modest, the mine tunnel is clearly narrow compared to the dungeon, and sometimes everyone has fairly good night vision, so it is not as troublesome with that level of light.

Even if it's rookie, it's like a beast around here.

When it comes to combustible gases, it would be better for me to use "light", but there is a policy not to use much magic this time, and since this is a working mine, it is not going to be a new place to dig, so the danger is low.

If dangerous gas continues to erupt, we won't be able to mine it.

Speaking of which, there was a lantern in the original world called a safety light with no danger of exploding in flammable gases... could it be sold by imitating it?

--No, the structure is simple, and we can imitate it right away.

If it's really dangerous, we have a choice of magic tools.

"Ke, it's pretty chilly...."

Uh-huh.

"Come on, let's get you in the mood"

The three seem rather nervous, perhaps because of the information gathered at the Adventurer Alliance yesterday.

Rank One and Rank Two.

That was the rank of the Unreturned Adventurer Party.

Whatever rank one is rookie, the rank two adventurer party is something no one can escape from.

Given that it exists in this tunnel, it is only natural that Sharia, who seems to be one of the lowest ranks, is nervous.

Rather, it is unnatural not to do so.

Mary and Meatier didn't seem very nervous about it.

I'm looking around at a large mine for the first time and it seems interesting.

"Dungeons have a different vibe."

"Really? Honestly, I'm feeling pretty tough here too... Is Mary the same?"

"Yes, I have trouble expressing it, but the air is somehow light."

"It's sensory, but I certainly don't feel different."

I didn't know when I only entered the dungeon, but when I came to a similar place like this, it seemed somehow different.

Is it magic drifting in space?

It may be because of my mind, but I feel more stressed by the dungeon.

Long-term stay, apart from narrowness (?) If so, will this one have less mental fatigue?

"Hmm, is that so? We've never been there before."

"I want to go someday...."

"Hmm? Really?"

"Yeah, I don't think we have enough power right now, but in the future! I knew I could make money."

"It's an adventurer's dream to grab thousands of dollars in a dungeon!"

"Seizing thousands of dollars...."

I don't know how you feel, but it seems quite difficult.

Even the summer dungeon, which we can only monopolize, has not yet been harvested enough to call it a "grab a thousand dollars".

The raw stones and so on sold well, but it's far from "living a lifetime of play". Given the cost required to equip the adventurer, it would be a pretty big bonus.

Nevertheless, you won't win unless you buy a lottery ticket.

I guess I can't help dreaming about it as an adventurer.

"Nao, for your information, what do you think we need to go to the dungeon?"

"That's what I need... yes, patience is what I need most"

There is a hierarchy in the summer dungeon that is often confused with the outdoors, but it is a minority.It is the defocus of the dungeon that continues through the dark and narrow passages.

Even though it's wider than this, it takes a lot of patience to sleep in such a place for a long time, and it will be an unbearable struggle for those who don't like it.

In addition, the living conditions are quite poor.

You can't clean your body without a decent toilet.

Lack of water, poor food, and trouble sleeping on the ground.

Dungeon exploration is impossible without a strong spirit that can withstand it.

"Hah. That's right, it's tough after all.Does Mary and Meatier endure that, too? That's amazing. "

Not only did Sharia say that, but also Agna and Tania turned to her respected gaze, and Mary awkwardly turned away.

"No, we...."

"There are Halka sisters, so there's no problem at all!"

For some reason, I was proud to name Halka Meetya.

"Meetya, you don't understand."

"Um, I remember. Nao's lover, right?"

Sharia had a good unexpected memory even though she should have given her name only once.

"Forget about it. --Halka can use magic.

"My troubles are all solved by magic!"

"Well, not all of it, but you don't have to struggle with cleanliness or water."

Naturally, we have no patience to withstand unclean and hostile environments, so without magic and magic bags, we would still have outlived the paste with the hunter's imitation.

"That's why it's one hand to find magical allies.Light magic and water magic are recommended. "

"That's hard. There's no one who can use magic with a beast."

"If we were based in Valm Grey, we might not be able to do it."

"It's hard to find even one of the elves ~"

Challenged in a slightly reprehensible tone, I'm stuck in words.

"Ugh, if that's what they say... I've been in the dungeon before, maybe it's better to talk to a party without a wizard."

Is mental strength and patience the only way to deal with it? Is there any way to deal with it?

Sometimes it's none of our business, and I don't really look around.

For high-value dungeons, the Alliance may be able to install a metastasis device, so it's probably outweighed by that.

"... well, even if you enter the dungeon, that's for the moment, isn't it?You just have to think about it before then. "

If you go to a dungeon city where adventurers gather, there will be a few people who can use magic.

We don't know if we can make friends with a small number of people, but it's more likely than finding them in Valm Grey.

"Rather, it's time to explore this tunnel.If you can't do this, entering a dungeon is like dying. "

"That's right! This tunnel is dangerous.--Is there a missing adventurer somewhere...? "

"Either way, there must be a trail."

The Guild staff asked me to "rescue him if possible," but he hasn't returned for more than a week.It is common sense that their survival is desperate.

If the purpose was to explore the dungeon, the survey of the tunnel was supposed to be a day trip, so the equipment was quite appropriate.

Except for exceptions like ours, it's hard to imagine bringing in large quantities of food.

If so, is it the body or the wreckage that will be found?

Either way, it is not hard to imagine that it has become quite a miserable substitute.

It will be difficult for us to take it home alone, and I'm sorry for the adventurer's family, but I honestly don't want them to find me.

"Yeah, I wonder if you can find the artifact...Now, take it easy. Where are we going? "

"We have to look everywhere, from the edge."

"It's huge, and I want to get around as efficiently as possible to avoid going through the same place twice."

"Because I have a map, I don't think it's good enough that I don't need mapping ~"

"That's pretty hard, isn't it? Can you do it?"

Unlike dungeons, mine tunnels are not that long in terms of distance from the entrance.

Speaking of why this is happening, you will soon know the purpose of the mine.

It takes a day from the entrance to the workplace, and if that happens, you can also stay at work, and transport the minerals you dug up.

Efficiency is poor for mining purposes.

In modern times, it is possible to develop transportation, such as cars and trains, to dig up to tens of kilometres deep, but in the case of this mine, all travel is on foot.

For this reason, even in the deepest place, digging is proceeding so that you can return from the entrance in about half a day.

However, the number of branch roads is quite large, and the total length of the tunnel seems to be several hundred kilometers, as predicted from the mayor's story.

They run like nets, so if you choose a good road, you can investigate efficiently, but with the lowest efficiency, the distance you walk is twice as long as the total - no, in some cases more.

The navigator's arms were about to be tested, but it was Mary and Argna who were chosen as such.

Speaking of why, the size of this tunnel is relevant.

The width is enough for two adults to be different, but to that extent, it is that much.

Mary and Argna's weapons are double-handed swords, and it is difficult to line up side-by-side when fighting with them.

As a result, they were downgraded militarily, leaving it to the Navigator.

"Mary, I'm counting on you to train in dungeon exploration."

"Um, I relied on Yuki for mapping, so such technology...."

It's hard to find the best route.

Even with higher education, it may not be possible.

I can't solve the problem of "going through all the routes at the shortest distance" even if I'm given a PC.

It is not clear how accurate the map itself is in the first place, so it is useless to think desperately.

"It's okay, it's okay. I don't think I can either."

"Well, if we don't loop the same place over and over again, we won't be here! It's up to you."

Mary relaxes her cheeks reassuringly to Tania, who slaps her shoulders casually.

"Okay, let's head this way first."

That's how we started walking in the direction Mary was pointing.
