When Jin returned to the junction of the branch tunnels, the others had just returned as well.

"Hey, how was Jin?　"This is what I got."

Reinhardt showed them the gemstones he had harvested. Two crystals and one amethyst.

I was like this.

Jin also shows his harvest.

"Well, three citrine crystals, three amethysts, and one smoky quartz crystal. That's impressive."

Reinhardt seems to have an idea how he found it. Well, one yellow citrine crystal and one amethyst crystal were dug out by the girl.

"I only found this one."

Elsa showed him the black crystal in her hand.

"All I found were crystals," said Reinhardt.

Reinhardt commented.

"Mother, this is a present for you.

The girl from earlier is presenting her mother, Baroness Sekat, with a stone she has dug out of the ground.

"Oh my God, are you sure?　Thank you, Sheide."

The girl's name is Siede. She is smiling as her mother pats her on the head.

Jin looked at her sideways and thought it was a good thing that he had made the magical pink sapphire.

"That brother gave me the place..." he hears her voice.

I can hear his voice. Then the baroness walked up to Jin,

"I see my daughter has been taken care of, thank you".

She thanked him.

"Excuse me, you are Marilia, right?"

Reinhardt called out from the side.

Yes, I am Marilia, and you are?

I am Reinhardt of the Shoro Kingdom. I am Reinhard of the Shoro Kingdom. I met your husband, Viscount Sekhat, the other day in Asunto.

Marilia heard this and said, "I am Reinhardt of the Shoro Kingdom. When Marilia heard this, she said,

"Oh, yes, of course. How is my husband?　I was worried when he came home late.

Yes, he was fine. But there was a little trouble at His Highness Ernesto's birthday party, and I think he's been sent to deal with the aftermath.

In this world where information transmission is slow, it seemed that Mrs. Reinhardt had not yet been informed of the golem outburst. So, Reinhardt told her only a few casual details.

She was relieved to hear from Reinhardt, who was there, that her husband was doing well.

"Your brother is late coming home.

Then she heard the voice of the girl, Siede. The only one who had not yet returned was her brother, the boy.

"Yes, Edem is late.

"I'm going to look for him."

With these words Sheide starts to run.

"Oh, don't run, it's dangerous!

said his mother, Marilia, just as he tripped and fell down.

"It hurts!

"Look, look, I told you,...... I'm in trouble, I can't do healing magic,......"

Then Elsa stepped forward,

"I'll do it. ......<>"

"Oh, it doesn't hurt anymore."

"Well, thank you very much, young lady. Come on, Seide, say thank you."

"Yes, ma'am. Thank you very much, sister.

She is an honest girl who thanks Elsa as soon as her mother tells her to.

"...... be careful, okay?"

"Yes, sir."

It is hard to see in the dark, but Elsa seems to be blushing a little.

"Mother!　I found an amazing rock!

Then Siede's brother Edem came back, shouting loudly.

"Look, look!　A green stone!　And it's a beautiful shape!

With these words, Edem held out the rough stone in his hand to his mother. Jin glanced at the stone and saw that it had a distinctive feature.

"It's a fluorite, isn't it?"

Erza heard him muttering in a whisper.

"Fluorite?"

"Hmm, ah. Was it Edem just now?　The stone he was holding. It had a beautiful octahedron, didn't it?　Fluorite can be broken into that kind of shape.

Fluorite is calcium fluoride. In fact, it is also used in iron manufacturing. Aside from the electric arc furnace in which Jin fell into, it was used in blast furnace iron manufacturing to facilitate the flow of impurities called "slag".

Therefore, it is a mineral with which Jin is very familiar.

As a gemstone, it is too soft (Mohs hardness 4), so only a few collectors collect it.

Perhaps this is another tourist service stone.

"Well, well, Edem, you found an amazing stone. I'm so happy for you."

"My brother, she found a pink stone."

"Well, that's great."

Yes, sir.

Jin did not mean to disturb the happy family. It's just... I just envy them a little bit.

"Yes, everyone, did you have a good time?　We are about to go outside, please follow me.

Then came the voice of the guide. Returning the borrowed magic tools, the eight of us headed back the way we came.

Outside, the clouds had parted and blue skies were peeking through. The wind was already blowing a spring breeze.

"Ah, it's nice to be out in the fresh air, isn't it?

Reinhardt agreed, and Erza was shaking her head in agreement.

"Well then, good day to you all."

Baroness Sekat greeted them. Shede waved his hand,

"Good-bye, brother, sister," she said.

Jin and Elsa gave a small wave back.

It was just lunchtime, so we decided to go into a nearby restaurant.

As it is a mining village, the restaurant was decorated with ores and gemstones of various sizes.

"Do you have any aquamarine?"

Elsa asked Jin in a small voice.

"Aquamarine, huh? I don't know..."

Aquamarine is a color similar to that of Erza's eyes. It is one of Elsa's favorite gemstones.

"Oh, this one does."

A fist-sized crystal was on display. Aquamarine is the same mineral as emerald, but while emerald crystallizes deep in the earth under great pressure, aquamarine usually forms in pegmatite.

"This is beautiful.

"It's beautiful even unpolished, isn't it?"

"Well, if the polished gem is a dressed-up beauty, the gem is a simple village girl."

"?　?　?"

"............"

Reinhardt interrupted suddenly. Jin and Erza couldn't help but make indescribable faces at his uncharacteristically impudent words.

"Huh?　I feel like I'm being thought of in a bad way."

Reinhardt sensed this and said with a wry smile,

"It's not my imagination. That kind of talk doesn't suit my brother Rai."

Erza let out her honest impression.

"That's terrible. I was going to ...... buy you that stone, but I'm not going to do it.

Reinhardt said in a sulky tone,

"I'm sorry. I'm sorry.

Elsa was leaning toward him saying, "My brother Rai is handsome. Reinhardt's smile deepens,

"I thought you've matured a bit, but you haven't changed a bit. Well, I'll buy it for you."

Reinhardt was sweet to his cousin.

"Is that sapphire still out there? ......"

The guide who had seen Siede give the sapphire to his mother, Viscountess Marilia Sekat, reported it to the mining association.

The tourist tunnels were closed for the next two weeks and mining was carried out, but little pink sapphire, or even just corundum, was extracted.
