"Actually, since earlier, you've been wondering, haven't you? Without putting it in the backpack, I hold it. Looks pretty heavy, but what about this?

"Well, for now, can you take a look?

Hulka opened one leather bag and put out a crystal ball, so I open the other too and line up next to it.

Try to line it up like this, but I can't find any difference at all.

Size, transparency, color, and a scratch-free surface.

Regardless of the industrial product, isn't it nearly impossible to polish the crystal by hand and make it this much sphere?

Or, if you're an amazing craftsman, is it possible?

Most of all, it wasn't made by people, it was from a dungeon.

"Is this... crystal, is it? That's amazing. It's quite a treasure, that's all it is."

"... oh, it's worth it too, naturally"

Hulka seems to have thought about it again, too, to Diola, who looks out for surprises, and nods Hmm.

We were looking at 'what kind of magic prop the hell', but there's no way this size crystal ball isn't worth it.

For example, it's a little too big to keep in my room, but some rich people like this.

"Crystals, after all, are they expensive?

"I hear that if you're a good wizard or alchemist, you can also make crystals, but naturally at this size, you're quite a forehead."

"Make... oh, it's quartz, the crystal"

To Ms Diola's reply, Natsuki nods immediately after a few thoughts.

But Toya's got a little caught up in that word, apparently.

"Hey, Nao. Is crystal quartz? Quartz, quartz glass or something, right?

"Right. That's it. Chemically speaking, silicon dioxide."

It's the same material as the bath bucket we made - probably.

Unless my magic has failed.

That thing is getting white and cloudy, but I guess my magic arm isn't enough.

Conversely, it would mean that as long as we improve our magic technology, we can also make transparent quartz on this crystal ball or so, as Diola says.

"So, what is it? Crystal balls, actually, glass balls?

I pinch my words while Yuki smiles bitterly at Toya for a look that kind of betrayed my expectations.

"Depending on the way you look at it, you mean so-yu. I also sold artificial crystal balls over there, which means it's just glass balls. Maybe some places use sodium glass, not quartz glass?

Sodium glass is glass mixed with silica sand with sodium carbonate and the like to lower the melting point and make it easier to handle, this is the majority of glass commonly used.

Speaking of quartz glass, which I've seen as a regular student, is it about a test tube to be used in chemical experiments?

Most of those test tubes are also made of sodium glass, but expensive quartz glass is used in some of them for experiments that cause high heat.

Teachers were told, 'Don't ever break it because it's expensive!?'.

Specifically, they charge between ten and twenty times the price.

Even though they look almost identical and can't be easily distinguished.

With that in mind, I don't find it surprising that there are vendors that use sodium glass for crystal ball materials.

"I'm also concerned about your value as a crystal ball, but what I'd like to ask Mr. Diola is something else. As I was concerned, this didn't fit in the magic bag. I don't know if it's some kind of magic trick, do you?

"Yes, I do."

"I knew it wasn't that easy. - Huh? Is there?"

To the answer that returned too lightly, Hulka shrugged for a moment and asked back again.

"Yes, for example, the transfer device installed by the Adventurer Alliance. You can't carry that part in a magic bag, either."

Oh, well. The Adventurer Alliance is installing a transfer device in the dungeon.

Do you also have the knowledge of that area? If you are also Deputy Branch Manager.

"That's a lot of heavy stuff, so it's hard to install, isn't it? Because we have to take it deep into the dungeon."

Most commonly, they don't carry it by hand, and the user of space-time magic sends it in "Transfer (Transport)," but the parts that don't go into the magic bag make space-time magic in general difficult, so that seems to be a big deal.

"Erm, I mean, space-time magic-related magic props don't go well with space-time magic?

"You will. Not all of them, but it's like you can't put a magic bag inside a magic bag."

"Then does this also mean space-time magic related magic props?

"I'm not an expert, so whatever. But that's likely, isn't it? Instead, don't you know Mr. Nao better?

I told Diola, "Can you make a magic bag? 'I can turn a gaze like that, but we are (...) or (...).

I can use magic, only a little over a year.

Sekiyama is enough to modify a little of what's in the magic book.

Research and all that stuff is refreshing.

"What do you want to do? Shall we buy it? Or should I turn it over to the appraisal? This is the magic prop we found in the dungeon, so you can use the appraisal at the standard price, right?

"Appraisal... is there a use for it? We have it."

"I still need to be an expert around that... What I can think of is an interior or something?

We have to snort at Mr. Diola like we're in trouble.

It would be magic props and space-time magic related to non-interior uses, but we don't know what they involve, so Mr. Diola would have trouble getting asked.

The current situation is useless, so it seems good to sell it, but the difficulty is that if you need it in the future, it won't be easy to get it?

"What do we do?

"... If you're safe, shall I keep it? Fortunately, there's golem material, so I'm not going to have a problem with the funds for the moment."

"Right. So, Mr. Diola, this fragment is a buyout, and can you turn one of the safe crystal balls to appraisal?

"I understand. Okay, I'll take this one back."

"Ah! Mr. Diola. I'll carry that later. Because it's pretty heavy."

Toya hastily held Mr. Diola's hand as she tried to lift the crystal ball.

"Right. Including the fragments, we'll carry them."

"Really? Thank you."

Well, I went home and weighed it, and it was almost 40 kilometers.

Fragments in addition to that.

I've left out the details, but with four minutes, it's over a hundred kilometers.

Mr. Diola is more powerful than she looks, too, but she's not the kind of thing you'd let a normal woman have.

And Meetia, who normally had it, is just fine.

"Speaking of heavy, in this dungeon, Rock, Stone, and Iron Golem came out. The only thing I took home was the iron, is it buyable?

"Are you Iron Golem!? That's amazing! When iron is picked, this is a pretty promising dungeon!!"

I meant to ask lightly, but coming back was an unexpectedly big reaction.

I ask back with a slight barometric pressure to Mr. Diola, whose eyes were rounded and his hips floated.

"So much, is it?

"Yes, iron is an important strategic supply. The territory with the dungeons where the Iron Golem comes out is quite moist. - Yeah, but it's a pretty deep place, isn't it? Is there a limited number of people who can bring it back...... No, depending on the number of occurrences, the installation of the transfer device may be permitted…? Is this when the Alliance leaps?

I put my hand on my chin and started worrying about 'mummy......' Diora.

Somehow we start to understand the seriousness of the situation, and we look at each other.

Honestly, 'I'm lucky I can get iron or something. It's troublesome to be heavy,' but when they say strategic supplies, they butt in a bit.

But what we should insist, we should insist properly.

I opened my mouth somewhat reluctantly.
