The business in Wang Du is over. I can leave right away, but I was caught by the women on the verge of saying "leave," so I'm staying in Wang Capital for a bit longer.

I've been motionless lately. Sometimes you want to get some rest. I have no objection there.

That's why you don't have anything in particular. If you insist, I'd like to buy some iron ore. I also want silver and copper ore at last.

By the way, Bilbao is a city of iron and not a city of mines, so ore is not easily accessible. What I want is a pre-processing stone. If you go to the artisan district of Wangdu, you can buy it normally.

When I left the inn, I said, "I'm going to the Craftsman's District now, but who wants to go? When I heard," everyone was going. He wants to rest, but he doesn't want to do anything. I don't know......

The Craftsman District is on the north side of the Wang Capital. Pretty far, so I ran on the roof and headed for it.

"Around here."

Down from the roof to the ground near the iron refinery.

"I kind of miss you"

Luna says emotionally. This is where me and Luna got our first request as adventurers. It was my job to carry iron chunks to the blacksmith's guild. Easy and cheap request. You won't take it again.

There must be a wholesaler of ore nearby. That said, there's just a big line of buildings around, and I don't know which one is the wholesaler. I looked at the building for a while and walked.

"Isn't that it, Mr. Coe?

When Luna checks the direction she points out, there is a pile of reddish stone next to the building. Speaking of which, I've never seen an iron ore. I wonder if that is...

Well, if it's loaded with inconsistent stones, I'm pretty sure it's some kind of ore.

"It's not that good, but it's iron ore"

Lily says as she looks out at the Stone Mountain.

"You know what?

"Oh. I'm still an investigator for the Blacksmith Guild."

Yes, I forgot. He is now a well-known investigator, but Mr. Lilly is qualified to be part of the Blacksmith Guild even soon. You're naturally familiar with metals and ores.

"Bad quality?

"Not as bad as I say, but not as good. If you want to buy it, pay attention to the price."

Amateurs might get bought at a high price. Looks like you should leave the negotiations to Mr. Lilly.

When I found someone who looked like a clerk and spoke up, I got a loving reply.

"There you are. Can I help you?

The clerk is a young man with a good-looking smile on his face. I mean the president's son, or I get the impression that he's a trailer son.

"I want iron, copper and silver ore. That's about 1,000 ounces each."

About 30 kg on a gram basis. Refining is manual, so it can't be processed even if it's too much.

"How do you use it?

"It's a refining exercise. The quality can be poor. Cheap stuff, please."

I want to practice increasing purity, so I'd prefer poor quality if possible. I'd rather have a garbage-like ore.

"If it's a magic tool of refinement, wouldn't it be awkward not to use high quality objects?

The clerk frowned and was surprised (a lot), but I didn't use magic props, so there was no problem.

I refine with my own magic. The purity obtained by this method is probably about 99%. Should be able to make this purity from any scum. I'd like to practice that.

"I told you it was practice. Using good stuff doesn't make practice."

"Really... wait a minute"

The clerk leaned his neck and disappeared into the building. I guess I'm definitely not convinced of that attitude.

"But why are they selling ore in the King's City when the mine isn't even close?"

"Oh, there's a reason for that."

Mr. Lily told me why.

That's because demon craftsmen test and research refineries. At the same time, it is for refiners to use the latest equipment.

The latest equipment has frequent faults and problems. Every time I call a magician who lives in Wangdu, it doesn't work, so I refine it in Wangdu, where researchers live.

Then don't use the latest equipment... but the quality and efficiency of the product are different, so they are introducing the latest equipment to compete in any refinery. He said he would relocate near the mine where the trouble was reduced and operate in full.

"I see. I don't know if it's efficient or not."

"I don't think that's a bad idea. And because of that, iron is abundant in this country."

While I was listening to Mr. Lily's explanation, it looks like the ore is ready. The clerk came back with a few stones.

"Thank you for waiting. Here's a sample."

It just looks like a stone to me, but it looks like some kind of ore. I shall leave the later negotiations to Mr Lilli.

"I'm sorry, but Lily will negotiate for me instead"

"I get it. Then let me show you."

Lily looks rugged looking at the stones handed to her by the clerk. I could see from the occasional tongue beating that I could hear that I was very grumpy.

"What's wrong?

"Whatever it takes is too harsh... none of it is less than garbage"

"Yeah... but just now I said it could be bad quality..."

"There will be limits!

Confused clerk and very grumpy Mr. Lily. The clerk just followed my instructions... I'm starting to feel a little sorry for him.

"Is it that bad?

"Right. It's not like it's going to be a very good sale. Impurities are too mixed. We can't even handle this stuff with the latest equipment."

Oh, on the contrary, isn't it convenient? Lily doesn't see where I'm refining, so she thinks I'm refining it with regular equipment.

"How much are you going to sell it for?

"Hmm? Are you going to buy it?

"Right. I'll buy it if it's not going to be cheap."

"Of course it is! I'll give you five gold coins for everything."

The clerk bends over and rubs his hand as he sweats from his forehead.

I don't know the market for ores, but they're pretty cheap. But Mr. Lily's face remains rugged.

"It's so much rubbish ore you don't even need for free, huh?

"Three gold coins is fine!

Oh, I'm down.

"I bought it!

"Mr. Coe? What are you going to do with this garbage..."

"I told you, it's practice. You should watch Lily too."

Let's demonstrate when we get back to the inn. That should convince you. Three gold coins in 30 kg each of iron, copper and silver. I got it super cheap. Assuming a 40% yield, it's a hell of a low price.

I gave the clerk three gold coins and stuffed the spare magic bag with ore. I left the ore store behind, mindful of Lily, who was all grumpy at first.

"Lily, I'm sorry you made up your mind."

"Nothing."

"No, I'm really sorry."

"Nothing. I'm not mad"

Mr. Lilli put his arms under his chest and turned to pussy.

I'm easily angry...... I said I'd leave it to the store clerk, but I said I'd leave it to him. Besides, I pushed off the opposite and decided to buy it. If this doesn't upset you, you're a saint.

I can't fix Mr. Lily's mood, so let's go into the proper cafeteria somewhere and demonstrate a little.

"What am I supposed to do here?

Mr. Lily is busy sitting in a chair with his arms in his arms. Pressured by that pressure, everyone bent over silently. The atmosphere sucks.

"Well, look at that."

That's what I say. Put magic through a grasp of scum ore.... I don't know what ore it is. I should have heard it first. Suitably tried with silver, copper and iron, turns out to be iron. Collect iron and divide the chunks into two parts.

The stone slowly separated on the palm of his hand, and a large chunk of cobbler and an iron-like chunk of ping-pong balls fell on the table.

Hmm...... good to see it went well.

"... What have you done now?

"It's refining. An old man I didn't know told me before."

It was an old man who happened to be next door when he left the outhouse. After all, I didn't know who it was.

"How do you do that? I didn't hear you could do that!

If you can do that, say it quickly. If you apply that to your magic props... there will be a revolution in iron making! Try it now! Try it now!

Lily's face changed dramatically from anger to surprise, and her upper mood. I guess I'm excited now.

"I'm also looking at what you've taught me, but it's not something anyone can do, is it?

Luna tells Mr. Lily calmly. Anyone can get to the point of melting iron, but it might be difficult to collect iron. I need an explanation of the atom.

"Damn... so is that. If anyone can do this, they should know better..."

Mr. Lily picks iron chunks and observes them with interest. It will not be hot anymore as it is cooled all at once when stiffened.

It is quite difficult to use this method as a magic prop. The process is too complicated, and collecting atoms depends on your senses. It's not an easy task to automate.

"So, how about this iron? You think you can use it?

The feeling is about 99% iron. I can't use it for weapon material, but I think I can use it for demon props.

"Enough. On the contrary, it is the finest. I've never even seen this much iron in a research facility."

Can you tell just by looking...... I can't tell between iron, steel and stainless steel. It all looks the same.

"You can do the same with silver and copper. That's why I'm glad it's garbage ore."

"Say that first...... There's no other technology you're hiding, is there?

Ms. Lily put her hands together in front of her own face and smiled at me. But I'm scared because my eyes aren't laughing.

"Ah...... and I can make a ruby"

It would be easier to say this too. From the aluminum in the soil, Ruby and Sapphire… or various columns can be made.

If I keep my mouth shut here, I don't know what they'll say later.

"Huh? Did I hear you wrong? Did you say Ruby?

Mr. Lily looks frivolous. You'd better demonstrate this too.

Indeed, the iron ore impurities should have contained aluminium. Multiply heat and pressure with magic to produce rubies. A bright red ruby with a big thumb gave a gnawed face from the wreckage of an iron ore that nearly collapsed on Guzguz.

"No, no, no, no, what's going on? Why is Ruby coming out of the garbage?

"There was a ruby ingredient in this. You can make blue ones, you can make transparent ones."

"No way, a diamond?

"I'm afraid I can't do that. I've tried so many times, it's only gonna be a shiny black chunk."

Whether you put heat on or pressure on it, it only makes a black chunk no matter how hard you try. I have no idea what's wrong, so I stopped the experiment.

"Right...... No, Ruby alone is amazing enough. Let's mass produce. Build Demonic Props for Mass Production"

Lily's eyes are ¥. That's awkward, I'm not going to mass produce it.

"The economy of this country will break. Please don't."

If you think so, Luna calmly notes. Mr. Lily turned back to me.

I'm relieved by Lily's usual reaction. Looks like I'm in a totally better mood.

For one thing, Mr. Lilly's mood problem could be solved. It's a rare craftsman's district, so I think I'll walk a little more once I've finished my snacks.
