"Boy, we don't have enough glass. Can you get some extra for me?

Again. I made it and left it there. "

"I can't help it. All the buildings you built in the castle town use glass. Besides, some merchants buy them."

"What? A merchant? You couldn't have sold the glass."

"Well, I guess I'll just buy it now because it's rare. But maybe there's a demand for it."

"Why not? You're making a sheet of glass for windows, right? There shouldn't be any buildings with windows in Fontana...."

"That's because you built this city. You actually saw the building with the windows and thought you could use it. I'm selling a lot of bricks, so I'm building a new building."

The old man who is looking at Vulcanian finances comes and places an additional order for glass.

But that was something I didn't think about.

There is a merchant who buys glass that has never been sold at all.

Although the number is still small, it seems likely to increase in the future.

When I heard about it, it seemed that the castle towns I had built had become a model house.

I can't ignore it because it's an old man's guess.

I've been magically making glass for years.

But the glass didn't sell at all.

I still think it would have been a little better around the money if it had sold a little more.

But now we're making a lot of glass that doesn't sell.

Since I built the castle town.

When I built the castle town, I thought it would be better to have as much uniformity as possible, so I built a building of the same shape with magic.

I mass-produced my house made by Gran, which I remembered in my brain, as a hardened brick building.

The building uses arched windows and doors to expand the space and increase the strength of the building, while keeping the number of bricks as low as possible.

In other words, we need the glass to build the building.

The amount of sheet glass that was being made meaninglessly gradually decreased.

We hurried to make enough.

Hmm, what's going on?

"Something's wrong, Ars."

"Gran. No, if there's going to be more demand for glass in the future, I think we should spell it out."

"... isn't that magic?"

"Hmm? Is there something you want to say?

"No, it's not a big deal, but I don't like to mass produce anything magically because I'm a maker."

"Really? Bricks are useful and helpful."

"Well, yes, but bricks and glass aren't the same."

"What do you mean? What's the difference?

"The cured bricks made by Ars are very user-friendly and suitable for mass production by magic, even from the point of view of the materials. And how about glass? Didn't you make different shapes of glass, such as dishes and glassware, apart from windows? Don't tell me you're going to spell them all out?

"No, I wish I had a window glass for now."

"I'm afraid not, Ars. You shouldn't make things with that feeling. You must always be uplifted by what you make. If you spell it, there will be no development from there. I think it's better to make glass by hand."

No, even if they say that, it's troublesome.

I'm not a grand maker.

But maybe Gran is right.

It is troublesome to prepare a lot of window glass, but it is subtle if it is enough to purposefully spell it so that everyone with a Balkan surname can make it.

Because you can build without using magic if you only need ingredients such as sand and lime.

However, since the window glass I make is based on the memories of the previous life, I think it is a glass that has developed well ahead of the times.

However, if I spell glassmaking, there is a possibility that I will never show up in Balka again to make glass by hand.

In the sense of technological development, there may be a negative effect of the curse culture.

"If you say so, Gran, try making something out of glass. I mean, if you can make it, I want you to make it."

"Well, what is it, Lord Ars?"

"Lenses. Lenses made of glass. Can you do it, Gran?"

So I suddenly asked Grand to make something.

"Fufufufu. It's finally done, Ars. This is the finished product."

"As always, it's amazing when it comes to manufacturing. You've been working almost all night."

"It's okay. Because I have a Balkan last name, I can use Meditation . You don't have to go to sleep."

No, [Meditation] is a spell to reduce wasteful magic spills and speed up fatigue recovery.

It is only used before going to bed to fully restore health while asleep.

Gran stayed up and worked with [Meditation].

You would be surprised because it was effective.

"Well, I can't help but tell you now. Well then, let's have a quick look."

I got it from Gran.

It was made with 5 types of glass lenses.

To be precise, I use 2 pairs of 5 types of glass, so I wonder if I use 10 pieces of glass.

"Oh, wow, you look so far. The accuracy is incredible, Gran."

I climbed the top of the outer wall tower and tried using it.

I use it to peek into my eyes.

What Gran made me was binoculars.

The structure of the binoculars that I remembered in vain.

Essentially, it is a system that can use multiple glasses to expand the distant ones.

But you can't just make glass lenses.

Five lenses should be sequentially placed in the barrel to refract light at an appropriate angle and make the subject's image appear larger.

My vague memory of the previous life alone could hardly be reproduced using magic.

Gran built it only on the blueprints of the binoculars that I dug up from the silly memories I wrote on paper.

I knew he was so good that he wasn't a hamster.

Looking at the Barca Knight Regiment from above the Tower, I once again thanked Gran for his presence.
