"Excuse me. My grandfather ...... gave me this."

He held out what looked like an old map.

"Oh, this is ......."

It showed the terrain north of Mitsuho.

"If you go all the way along the mountain to the northwest of here, there is a wetland called Siklo Marsh," he said. On the east side of it, there is, or was, a village called Ulun.

He means that he does not know if there is still a village called Ulun.

"I see, thank you. It's not very valuable, is it?"

"No, it is nothing compared to what Mr. Jin did for me.

However, it would be awkward to carry around the old map as it is. Jin asked Reiko to make a copy of the map.

He asked Reiko to bring a large piece of wooden paper, and she copied the map.

She does so at a blinding ...... speed,

"It's amazing......".

Mii was amazed at the speed and accuracy of the copying.

In about three minutes, the copying of the old map is completed.

"Thank you. You can keep the original for yourself.

Jin carefully folded the old map back into its original shape and returned it to Mii.

Mii joined them for tea. Pickles were served for tea.

We sipped green tea while munching on the pickled cucumber-like vegetable.

"But you are leaving already, aren't you? ......"

Mii said sadly with an expression that didn't fit the heartwarming atmosphere.

"Well, that was the plan, and I can't stay here forever."

Saki, sitting next to Mii, consoles her.

"Yes, that's right. ....... I'm sorry to leave you."

Looking at Saki's face, Mii smiled a little sadly.

After that, the main talk was by Jin and the others.

Mii was happy when I told her about the Shoro Kingdom.

"Saki-san is a wonderful person, isn't she?

Mii and Saki were somehow close to each other.

"Oh, really?

"Yes, you look nice with those glasses on your face."

"Well, I don't know, people over here don't seem to be surprised to see glasses on your face, do they?"

Saki wants to keep a little distance, but Mii doesn't seem to let her.

Jin and Erza are looking at Saki, a rare sight.

"Yes. I'm using it."

"What?"

"My grandfather has them too. Reading glasses, he says.

I see. ......

A wise man (Mags) who has created all this stuff should have at least made glasses.

Jin thought that the reason these people did not wear glasses was simply because they did not have bad eyesight.

But they seem to be getting presbyopia.

Jin remembered that the glass used here was not quartz glass.

Quartz and crystal are made of SiO2, and mixing sodium carbonate (Na2CO3) and calcium carbonate (CaCO3) lowers its melting point to about 1000℃, making it suitable for mass production.

Since Jin does not have such knowledge, he only uses quartz glass when he talks about glass.

Quartz glass has a melting point of over 2,000°C and low fluidity, making it very difficult to process.

（No doubt, Mags has some knowledge of chemistry.

Jin was looking forward to the northern lands he had yet to see.

"Saki-san, yes, ah!

"I can eat it by myself!"

Saki was flabbergasted by Mii's aggression.

Erza felt relieved, frustrated, ......, and sorry for Saki, as Mii's target had shifted from her to Saki, with mixed feelings.
