"Surely the one called this rubber is interesting. But I don't think this is going to be gold any time soon. Hmmm, all I can think about right away is making a lot of this and making it into a material that protects it from breaking when carrying something fragile... and then sticking it to the handles of a bamboo or sword to prevent it from slipping? And then, I wonder what. I don't know."

Heggard likes the feel, he says, not paying attention to the black one I'm lifting, messing with the white raw rubber. Enough answers. I don't take advantage of some of the features, but I guess it would be hard to come up with this much without knowledge. I'm a lord, so if there's anything I want to find a use for it, it's fine.

"I wasn't sure how to use this when I found it either. At first I tried to touch and stick with the sap dripping, and I didn't feel anything that far. At one point, when the sap dried, the stickiness decreased and I found it a little dull. I've been messing with a lot of things to see if that helps anything. So the white one was the first to do it."

"Uh, speaking of which, when you went around, you had some kind of little barrel. Is that it...... So, how do you make this? Is that gonna take a lot of work?

I started explaining how I got the rubber.

"It doesn't take much effort. It's that sap, but even if I let it go and set it aside, it will solidify, but I found that it takes a lot of time to solidify it that far. Moreover, it does not solidify beautifully, but only partially and only on the surface. Also, when you're on fire, there's brown water coming out of the tree, right?

At one point, I zeroed the sap in that brown water, but I was curious because the sap started to solidify, and I tried a lot of things to see if I could magically solidify it. And after all I've tried, I've found that when I dry it with ground magic and water magic, fire magic and no magic, it hardens all the way inside at once. "

Of course, the fire is cod. I wanted vinegar but I didn't have it at home, and I can't even talk to you about such a useless use of it to make beer rot. I just used wood vinegar liquid because I couldn't help it. Since then, I've been magically making acid to increase efficiency. I said dry only because it's troublesome explaining chemical changes, but you could talk about it someday.

"Oh, you brothers have so much magic... I say that dry magic is usually only used when skinning special demons...... I know it's okay because it's about you, but no one's gonna see you."

"Yes, I did it all in the house storage, so there's no problem there. But simply drying it also solidifies mixed things like debris and wood chips in the sap together, so I noticed that it would be more beautiful to dissolve them in water once and even more before drying them with anesthetic cloth. And it's the white one who took as much mixing as he could and made it."

"Right. Mixed things like this are called 'impurities'. But this feels good like sucking on your hand."

This is how Heggard often teaches me the language. I guess this is Heggard's education, I see him teaching Farn and Miloo the language a lot too. I think educational enthusiasm is a good thing. That's right, and did you like that feeling so much? Heggard has been messing with white raw rubber since just now.

"'Impurities,' right? I get it. So, its rubber, but it stretches well, and when it shrinks, it returns to its original shape. But if you stretch too much with strong force, the limits will come and go."

"Humph..."

Heggard began to prolong the raw rubber as he heard it. Leave it to your previous level 15 muscle strength to pull. Oh, let's stop it before it hangs up and hurts.

"Father, if you pull any more, you'll hang up. It hurts when rubber hits you with a shrinking momentum."

"Oh? Right. But I'd like to try it. Can I hang up?

"I don't mind that..."

Ooh, wow. I'm stretching a small rubber nearly 1m thick and about 14-15cm long. Oh, don't hang up.

Batchin!

"Ouch!! That hurts."

"That's why you said it. So, its whiter, but it's a big feature of being soft and well stretched and shrunk. Still, I'm sure it'll help enough."

"Mm-hmm. Right? Isn't that enough to play with other than what I just said?

"No, for example."

When I said that, I received the larger pieces of raw rubber from Heggard and put out the knife. Cut an elongated string out of the rubber mass with a knife.

"This is how I make elongated strings out of rubber. And if you circle it up and use it for pants and other clothing, it saves you the hassle of tying your hips."

"It's convenient, but I don't think it's going to be gold."

I said it with a slightly disappointing look on my face.

"That's true. This is just a little convenient. This is just one example of the use of rubber that I've been thinking about. But I'm going to make this string a little thicker."

Now cut out about 1 cm thick. A string about 10 cm long was removed. I don't care if this is a pose. I say as I give the chopped string to Heggard.

"I'd really rather be a little longer, but I'm not using this, so fine"

Next I took out the Y-shaped tree I had inserted in my right butt pocket and the pebble out of my front right pocket. It's a pussy. The pussy is fitted with a rubber string about 30 cm long, about the same thickness as the rubber string I just cut out. I don't dare wear a belt. I bounce up a window and set a pebble on my pussy and it strikes out toward me.

"!? Ooh, ooh. Is it like an easy bow...... What about the power?

He seemed quite surprised by this and said it as impressive at the same time.

"I made this using the same rubber. It's just different in length from what I just cut. The power depends on the length and thickness of the rubber string, the length of the pull, and the bullet you fly. If you don't hit people with this, you won't get hurt."

"I see, well... you mean we should improve..."

Heggard watching his pussy as he pulled the rubber string, but said as he noticed.

"That's right. If it's rubber as it is, it needs to be thicker and longer, and the body should be combined to make it bigger, or it should be made of metal, not wood like this. When that happens, it gets big and heavy. That's what I thought, and I thought we needed to build something that would be harder to cut off and easier to stretch and shrink."

"Yeah. So it's the black one who made it?

"Yes, but actually, the black one was a failure."

"? Did you bring your failures on purpose?

Says Heggard in wonder. Especially.

"This black one was made while mixing things up to make the rubber sturdy at the same size somehow."

"In the end, did you do it?

It's already my fault. But I can't help it. I know how you feel.

"I did it for once. Though it turned brown. Before I made the white one, before it dried and solidified in the sap phase, I worked it out and mixed it with a little bit of the northern mountain stone."

Brown-looking rubber strings were removed from the pockets where the pebbles were removed. I'll give it to you because Heggard will get his hands on it.

"Hmm? Isn't that how you make the black one? Sort of... thinner than just now. But the stretch is better this way. And you have a strong ability to shrink."

"This is what happens when you make something just like that with this rubber"

Remove the smaller pussy from the left butt pocket earlier.

"Mm, that's a lot smaller. Now, more than I said earlier," The power is better this way. "

"Right...... I'll try it later."

Heggard says as he was quite impressed. So, shall we get to the point?

"That was what I was aiming for, but the black one earlier, that's right. It's the one who said it was a failure. This was done while trying to make that brown one and try to improve the white one. But the true finished product could be this way. This black one hardly stretches and shrinks, and it's just a little heavy because it has a lot of mixing, but it's very sturdy. I think I have more use for this one."

"What do you mean? If it's less stretchy and heavy, I'd prefer white or brown rubber, wouldn't I? Even if it's tough, the trees are tougher, right?

Originally there were no rubber products in this oath world, so there is no imposition. You wouldn't even know the characteristics of the rubber you haven't explained yet.

"Right. At first glance, this black rubber seems to have narrowed its use. But I haven't lost any of my elasticity either. I noticed this as I was making it, but if you lose the elasticity to stretch and shrink by the mix, it will be hard and sturdy for that matter. This sturdiness outweighs the tree by the way it is made. Also, it's not like it's going to lose any elasticity at all, so if it's a little bit after you make something, it's going to deform."

"Um, I don't know, is it true that it's going to be tougher than a tree?

Oh, have you eaten there? But let me explain that a little further.

"Yes, I will now explain what I thought was the use of these rubber products. The first white one, I call it raw rubber because I only solidified it with sap, but I didn't really think of this use. Thinly plated and laid on a horse's saddle, banded and wrapped around some pattern to slip away, then again plated and laid on the bottom of boots, shoes and sandals so it's easy to walk...... oh, the bottom in the shoe. I don't mind behind my shoes, but it's soft, so this is the only thing that will cut you right off.

Next is the brown one, but this is tougher and more stretchy than raw rubber. But equally easily cut with a blade. The usage, as I said earlier, will be used for clothing, for the jumping gear just now, and this one can also be used for shoes. Also, it would be easier to pack if it were a string of some thickness.

I think that if you make a bag with this, you can do something better than a water bottle made of goat or pig stomach or skin. Oh, yeah. Rubber does not pass through water once it is dried and solidified. So now you can make barrels and other plugs, and you can also make it easy to make plugs for the water bottles that you have now. "

"Hmm, sounds like you could do a lot of things."

Feeling a little more fond of rubber?

"And it's this black one. I powdered and mixed this with charcoal in addition to the northern mountain stones I used to make brown rubber. That's why the color is black. Mixing the northern mountain stones with powdered ones initially stretches and shrinks better and becomes sturdy, but seems to have limitations. Add charcoal and it will stretch and shrink worse, but it will be stiff and sturdy. Try to sharpen or cut it a little."

That's what I say and I give you the knife. Heggard seems a little stunned because he puts a knife on the black rubber but is stiffer than I thought.

"This is... stiff. Not as sharp as you can scrape. Pretty sturdy. This could be harder than a tree."

"It's pretty hard, right, so should I say hard rubber? Try cutting this next time."

I further remove the rectangular black rubber about 5mm thick and 2cm wide and 10cm long from the front left pocket.

"! Mm...... You have a lot of power to sharpen this. This knife won't cut you off easily. So small..."

"This was made over time by mixing as much coal powder as possible with stone powder from the northern mountains. It's getting heavier, but it should be lighter than metal or normal wood, and it's pretty sturdy, right?

If you put this in just the right shape, you might be able to use it for armor and other martial arts, and if you have hard rubber, you can make sturdy shoes if you strap them on the bottom of your shoes. Not that it won't scrape, of course, and although it's not as sturdy as metal. This one looks like sandalwood (ebony), so I named it Ebonite. "

My father's eyes have changed. This looks good.

"How much can this be made in a day?

"The sap that serves as the raw material can only be taken a little in a day from a single tree. If you rubber it, the portion will be about a third of that. So you can make it in a day with ten trees in about that booklet right now."

"That tree, a tree that can take sap, but where and how long does it grow?

You look pretty serious.

"Is it about two to three hundred copies to the southwest of the village? I don't know exactly because I didn't count it."

"Okay. And how much magic do you use to make rubber out of sap? Do you think Charles could do it?

Sounds like a pretty good eater. Sounds like this should work.

"I find it difficult because I use earthly magic. My sister might be able to make it without any problems. But the ingredients, other than the sap, are the water and the north mountain stone when you burn the tree, charcoal, so anyone can make it without magic, if you don't even make the wrong time and procedure. All the rubber I've just shown you is made without magic."

"Well, there seems to be a lot of use for rubber. Try to make something you can use. If you're going to sell it, you can make a little more and go sell it to Dorrit. Think about horses when they sell well."

That's why we've been developing rubber products for a while. Try your best.
