"Boy, you don't have enough glass. Can you get me some extra?
"Again. I've been making and putting away quite a bit."
"You can't help it. All the buildings you built in Castle Town use glass. And some merchants will buy it."
"What? A merchant? You couldn't have sold the glass."
"I guess I'll just buy it now for rarity. It's just that maybe there's a demand."
"Why not? What we're making right now is sheet glass for windows, right? There's no building in the city of Fontana with windows..."
"Well, that's because you built this city. You actually saw a building with windows and thought it could be used. They're selling bricks in the mountains, so they're building a new building."
An old man comes looking at Vulcania's finances and places an additional order for glass.
But that was something I didn't think about.
They say there are merchants who are going to buy glass that they have never sold.
Although that number is still small, it seems that it may increase in the future.
Looks like the castle township building I built became a model house.
It's an old man's account I was in business with, so I can't ignore it either.
I've been magically making glass for years now.
But I couldn't sell that glass.
I still think it would have been better if that had sold me some more gold.
But now I'm making a lot of glass that can't sell like that.
Since I built Castle Town.
When I built the castle, I magically built the same building, wondering if it would be as uniform as possible.
[Storage] I mass-produced my house made by Gran, which I remember in my brain, as a hardened brick building.
While this building keeps the number of bricks as low as possible, it uses many arched windows and doors to make the space wider and increase the strength of the building.
I mean, I just needed glass for what I built.
Sheet glass, which had been meaninglessly made all over the place, is dwindling.
He hastened to make more than enough.
"Hmm, what's up with that?"
"What's wrong, Lord Ars?"
"Gran. No, if there's ever going to be more demand for glass in the future, it's better to spell glass making."
"... is it magic"
"Hmm? You got something to say?
"No, it's not a big deal, but the awkward don't like mass-producing anything magically because of the maker."
"Really? Bricks are handy and helpful."
"Well, yes, but brick and glass would be different"
"What do you mean? What's the difference?
"The hardened bricks made by Lord Ars are very user-friendly and are suitable for mass production by magic, even in terms of materials. And what about glass? Didn't they make dishes, glasses and other dishes in various forms of glass, apart from for windows? Are you telling me you're going to spell them all?
"No, for now, I wish I had windows"
"I can't, Lord Ars. You shouldn't make things that way. You must always be uplifted by what you make. When you spell it, there's no development from it. You should also make glass by the hands of people."
No, I'm in trouble for you to say that.
I'm not a grand builder.
But maybe Gran's right, too.
It's troublesome to prepare lots of windowsills, but it's subtle if it just makes sense to purposefully spell them out and allow everyone with the Barca surname to make them.
Because even ingredients like blah blah blah blah sand and lime can be made without magic.
However, since the windows I make are based on memories from previous lives, I think they are developed glass that is quite a bit ahead of the times.
It is also possible that my spellmaking of glass will prevent Barca from showing up again in the future to try to make glass by hand.
There may be negative effects of curse culture in the sense of technological development.
"If you say so much, 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?"
"Lens. Lens made of glass. Can you do it, Gran?"
That's how I suddenly asked to make things for Gran.
"Pfft. It's finally done, Lord Ars. This is the finished product."
"It's amazing when it comes to making things the same way. Haven't you been working on it most of the time?"
"It's okay. Awkward people can also use [meditation] because they have the last name of Barca. You don't have to sleep."
No, no, [meditation] is a spell to reduce wasteful magic spills and speed up fatigue recovery.
It's only for you to use before you go to bed and restore your full health while you sleep.
That's what Gran used [meditation] to stay awake all the time and do his work.
You'd be surprised how effective it was.
"Well, I can't help but say it to you. Well, it's my fault, and I think I'll let you see it soon."
What I received from Gran.
It was made from 5 different glass lenses.
To be precise, does it mean that I use 10 pieces of glass because I use 2 sets of 5 different types of glass?
"Oh, wow - I can see far away. Precision is amazing, Gran."
I'll climb to the top of the outer wall tower and use that.
Something that I use to put a peek into both my eyes.
What Gran made me was binoculars.
The structure of the binoculars that I remembered for my blush.
Basically, it is a mechanism by which multiple glasses can be used to try and enlarge the distant ones.
But you can't just make it by having a glass lens.
Five types of lenses must be arranged sequentially in the barrel to refract light at an appropriate angle and to make the image of the object appear large.
My vague memories of my past life alone could not be reproduced with magic.
Gran created it based solely on the blueprints of the binoculars I dug up from the blurry memories I wrote on the paper.
I knew this guy was capable enough not to hammer it.
Looking over the Barca Knight's Lands from the top of the tower, I thanked Gran once again for his presence.
