Reach the basement 31st floor.

There are some things you need to do before you can start exploring.

"Iris, you go home to the mansion."

"I'd also like to explore the type of places I see for the first time as an adventurer..."

"No."

Force Illis, who wants to accompany him, to go home.

"Are you ready?

"Yes."

Melissa magically keeps the ambient temperature comfortable.

There is still a distance to the melting furnace downstairs but it feels a little hotter. It won't be a problem to keep measures in place from now on.

Continue along the rock path.

"It's a little different than a pit..."

"Yes, it looks like the ore can be mined as well, but it looks like it can be mined a little special"

Since the 31st basement floor it has become a huge circular field, with melted iron hanging like the sea at the bottom, flowing from the middle to the lower.

There are several means of moving down.

A spiral path that continues along the circle.

There is a tower-like facility in the middle of the field, where the path to the facility leads to a spiral path.

Hard walls on the outside.

[Map] can also be used to check the type of ore in the rock bed.

Looks like you can scrape it like a mine and get iron ore, but there are a few places that have had strange reactions that you've never seen before.

"I wonder what this is"

When I tried using [Appraisal (Analyze)], the name "Curse Stone" came up.

"Curse Stone"?

It's an ore with a name I've never heard of.

I'll see how the other members are doing for a try, but they haven't all heard of it.

"Well, now it's a lost stone."

"You know what?

They know the labyrinth nucleus (dungeon core).

Listen to the labyrinth nucleus (dungeon core) as you walk.

'I've only heard the name before, for once. Simply put, the word "curse stone" is an indispensable substitute for building the Devil's Sword.

"Huh..."

"Do you know what demon swords are made of in the first place?

That said, I never even thought about it.

I didn't even think about how to make it because my eyes went all the way to its powerful effects and its price.

"The Devil's Sword is created by striking iron, just like a normal sword, but by imposing a powerful curse at that time."

"Is that possible?

I've heard about the spell itself.

I have seen objects that have been given that effect as one of the magic tools sold.

However, there are extremely few people who can handle spells that can curse people, and there is a low chance of success in imparting them to tools, and in some cases the curse has to come back to them when they fail.

That's why I'm not out.

Occasionally you can get it from a chest in a labyrinth or ruin.

It is also possible to use a chest (Treasure Box) as a Labyrinth Master (Dungeon Master), but I have never actually acquired it because the more powerful a cursed tool it is, the more magical it consumes.

The effect was also possible to reproduce by labyrinth magic, so it did not have the benefit of just being worthy of consideration.

"There are more ways to keep risks and consideration down than the Lord knows."

That's the purification method using 'Curse Stone'.

"Curse Stone" possesses the characteristics of accepting negative emotions such as resentment and hatred. So you can produce a sword with powerful effects just by striking a sword hating someone. It's just that being a cursed sword doesn't make any difference, so I'm asking for some kind of price. "

That is the formation of the Devil's Sword.

At one point, they demanded a powerful sword to counter the demons.

A troubled blacksmith got his hands on the Devil's Sword using the 'Curse Stone'.

This method made mass production possible, and a leading blacksmith made it possible to supply it steadily.

"How come it's now obsolete?

"Simply because the" curse stone "is gone."

"Curse Stone" is also an endless resource.

Purification methods relying on special materials have been lost with the disappearance of special materials.

"Didn't you try to make it artificially?

Melissa asked looking at the surroundings that seemed abundant.

'Unfortunately, even though I knew how to refine the "curse stone," it was a difficult substitute for artificial refining due to ethical issues. So I had to give up.'

"Ethical issues, is it?

"What you need to refine the" Curse Stone "is negative emotion."

"Like 'grudge' or something?

If you look at what the demon sword users say and do, you somehow understand.

Hopkins is jealous of being ridiculed.

Pal's dissatisfaction with the status quo due to the loss of his parents.

Gem is angry at his irrationality given to himself and his friends.

Redo has his own sense of overdone justice.

I guess those emotions are necessary for 'Curse Stone'.

"Yeah. That much emotion. Then even with 1,000 people, it's less than a" curse stone "that can build one demon sword."

"So how did you get all this' curse stone 'ready?

Probably used by Lüze. The only remaining "Cursed Stone" left me with enough to build ten Demon Swords.

But given the traces of the digs, I'm pretty sure I could have made nearly 1,000.

How did you prepare all that 'curse stone'?

"There is, isn't there? There's an event in which technology has developed to extremes prosperity but in an instant everything has been unreasonably deprived. '

"Catastrophe, huh?"

"You're right, Noel."

Life in a dark place called the Labyrinth.

Less food that can't feed everyone.

Stress caused by being forced to live in closed spaces.

After the catastrophe, we had various problems.

"It seems that the evacuation life took decades depending on the location. I wonder how much time anyone who was evacuating here lived with a grudge against the catastrophe. '

The people forced to live in evacuation came alive with resentment.

"No way, the ground looked relaxed right now."

Areas famous for their livestock raising cattle, goats, etc.

It didn't look like a very resentful land.

'Cause a lot of time has passed since the catastrophe. I guess the ground was completely purified. But if you're underground...'

I continued to build up resentment in an extended way.

Moreover, after the 31st basement floor, there are facilities that are easy to process "curse stones".

Those conditions combine to occasionally produce demonic swords. The created demon sword will only be stored near the lowest level, but occasionally... there is a miraculous chance that it will be mistakenly installed on the upper level.

"It was your father who caught that miraculous odds."

"I don't know what that is."

Are you lucky or bad?

No, I guess I was unlucky considering what happened after that.

My family left one behind and everyone died because by chance I had found the Devil's Sword, and I had to live a lonely day with every one left behind.

"Hey, is there ever going to be a demon sword?

'Right. The facilities necessary to produce the Devil's Sword remain. However, it takes a lot of time to prepare the "Curse Stone". I wonder if we can produce one demon sword in decades if it doesn't even happen on a massive scale?

"Then don't worry."

Most of the "Curse Stones" found in the Labyrinth were consumed and brought back by Lüze for Demon Sword Refining, so the amount of "Curse Stones" left is negligible.

You can say Antai for a while as long as you do something about the 'curse stone' left over.

"Better not have anything but this tragedy."

Renew your resolve.

Then I saw a knight armor from the front - a golem walking in.

The path along the outer circumference is in a straight line. There are paths that allow you to travel to the tower in the center, but there are more demons waiting for you in the tower.

Fighting the Golem is inevitable.

'This field has no trouble with the materials needed to make the golem. I guess there's a lot of demons like that.'

"I'm sorry, but we're in a hurry. Stay out of my way."

Ira, who pulled out her sword, runs.
