Transported to a hyper-realistic RPG.

"That's why your husband always thinks scientifically when he uses magic."

"There are magic and magic and things that cannot be explained scientifically, but the phenomenon that is happening is science." You can predict and guess what will happen. If you know that, you may be able to avoid danger or handle the opponent's attacks well. That's what I thought. "

”Wow, that's amazing... using science to drop your survival rate and attack power...”

What surprised me was Sura Tan.

"In this case, magic is used as a matter of course in battle." In addition to attacking with swords and spears, it also requires scientific thinking. I know that and I can't let it get out of my hands. "

If you're just fighting with weapons, you don't need much scientific... especially chemical knowledge because it's just about the flesh. That's why your physical abilities such as power and speed are so high, and the difference between your abilities and your opponents is definite. It's like a war in the Warring States Period, like a coliseum.

However, magic is always present in battles in this world. If the phenomenon caused by magic is a scientific or chemical phenomenon, that knowledge is bound to be useful.

In modern warfare on Earth, scientific phenomena are dropped into weapons, so it is very different if you have knowledge.

It would have been helpful if we knew how to stop a chemical reaction or weaken it against a weapon that uses it.

In this world, it's not a scientific weapon, it's just magic.

In the case of Surakutan, there is no problem because to some extent, we are unconsciously thinking of dealing with the magical phenomenon from scientific knowledge. However, when it comes to words, your consciousness will be oriented towards what you were doing unconsciously.

What I'm saying right now is that I'm amazing... that I was unconscious, but when I try to say it, I think it's a word that comes out of emotions like...

"I must also learn science to the extent that such an idea comes to mind..."

"I'm sure you're used to this, so I don't think it's something you can do right away."

“Yes, I'll do my best”.

I think Nil is a genius in effort, and you'll soon learn how to think like that. However, it's not like I'm going to do it right away, so I'll tell you what I can teach you.

"More than that, there's a lot of talk going on from the point of view...?"

"That's right! Fountain pens!"

I'll tell you as much information as I know. "

That's what he told me...

First of all, it seems that the nibs were mainly made of acids, alkali or base-resistant gold alloys, and metals such as stainless steel. Furthermore, since the tip of the pen is rubbed with paper many times, a metal that is resistant to abrasion is used elsewhere.

In addition, there is an incision from the tip to the central part of the pen tip, and a hole is drilled in the central part, which is the end point of the incision.

The opposite side of the tip is where the ink is put. From there, the capillary phenomenon is used to send ink to the pen tip.

It seems that I don't know anything about it, but there seem to be many other ways to do it. If you say something in detail, there seems to be a convenient way to add more.

However, even if the ink is not intentionally added, it can be used as a fountain pen as long as the ink comes out in one go until the ink in the cartridge disappears. It seems that the minimum necessary mechanism is around here.

"The slit... that is, when I pressed the pen against it, it opened and the ink was flowing. If the ink was sucked into the paper in a capillary fashion, the ink would flow out of the cartridge and the same volume of air would be sucked into the cartridge.”

Oh, is it harder to use a cartridge...?

"No, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no. No, no, no, no, no, no, no

Even though the ink is sucked out by the capillary phenomenon, you have to make an exquisite incision size that doesn't fall off with a bump, and it should be difficult to just make a pen tip. ”

Oh, oh...

I told you it would be easier than a training bow, but it seemed like I was getting on my feet... I can see that when I tried to make it myself, but the technology of the original world was really amazing.

It could even be harder than making a bow.

However, because of Nil and Piltee, I decided to make a fountain pen from scratch, so I decided to make a blueprint that was hard to imagine.

Is there an empty hole in the center of this pen that connects to the slit?

"I wonder what it was... I think it was a hole to determine the elasticity of the pen tip..."

Isn't this a place to store ink temporarily?

"That's why there must have been another mechanism."

I thought it was a place to store ink temporarily, too, so it's not! I have a surprising memory of it. "

"Hee..."

If you increase the diameter of the hole, the left and right sides of the cutout will open wide when you write it, and if you reduce it, it will not open much. From the point of view of the person who is using it, it can be felt as the elasticity when pressing the pen. Probably… maybe.

In other words, this hole is also one of the most important parts. Whether it feels too soft or too hard, it will make you feel uncomfortable to use it.

"I wonder what kind of metal it will be made of.....

It has low reactivity to acids and bases, and it's quite flexible... so it turns out that gold is the best. "

For once, the magical results of the appraisal regarding the money...

[Gold... gold. A rare metal, also known as gold. Extensive ductility, very low reactivity.]

It will be something like that.

For now, as a result of the appraisal, it seems that the gold in this world has special characteristics... Something may come up when you use it, but the basic characteristics will not change.

"That's right. I agree with you about spending money." I think it is more difficult to think of other metals that can be used.

I just don't think money alone will do the trick. ”

"It's too soft for nearly 100 percent pure gold."

"In the past, we used to tell if it was real or not by whether it would leave a trace when we bit the bamboo shoots..."

However, if you do that, you're going to make an alloy, but you don't know... how much to put in.

Indeed, since twenty-four gold was pure gold... seventy-five percent of the eighteen gold is gold. "

"Do you mean to put 25% of another metal into an alloy?"

"I don't even remember what I made in the Rock... I think it was silver or copper..."

"... no, I think I'll use Lytium this time."

Lytium... it's the only metal we have, isn't it?

“Yeah. It's a commonly used metal, which is light, tough, and rust resistant.”

It is a metal that has been used before, and the results of the appraisal are as follows.

[Lytium… a common metal. Light, durable and resistant to rust. The melting point is 800 degrees.]

"Resistant to rust means that it is resistant to oxidation, so it is probably a metal with low reactivity.

Because the melting point of the gold is 164 degrees... "

Do you remember the melting point of gold very well?

"I often see the melting point of gold, silver, copper, iron and other famous metals when I'm studying, so it somehow stays in my head."

"That's amazing..."

I'm sure I've seen it somewhere, but I don't remember it at all. I was probably thinking about it like a thousand degrees... or something like that.

"It was just a memory, so it's not amazing."

That's amazing, but...

"Anyway, what happens when you melt, mix, and chill?"

I don't know whether it will be a good alloy or not, so I'll have to do a little digging around here.

"Eighteen gold is only a guide, and I don't know if it's the best percentage for the alloy with Lytium."

And what are you going to do with the tip of the pen? "

"Indeed... there must have been a metal in the description that was an abrasion-resistant metal such as Abrarium." I thought I'd use it. "

The result of the appraisal magic was as follows.

[Abrarium… a common metal. Excellent abrasion resistance.]

This is also a metal that is only in this world, and I have no knowledge at all, so I think there are few explanatory statements.

"In other words, the gold and lyetium alloy is made in the form of a pen tip, and the tip is melted and ball-shaped with ablarium. It's like putting holes and cuts in there."

"It sounds super easy to put into words..."

"Hopefully we can make it right away... but I think this is a compromise."

Looking for the perfect fit! I don't think about it, but I want it to be something that is quite comfortable to use.

What I'm going to say here is, how much level are we going to set?

I-If you write it down, neither me nor Pilate will have any problems.

“No, I want to make it feel good.”

"Hahaha. It's hard to call that a good feeling."

Sura Tan seems to understand my feelings and laughs.

I don't want to see Nil and Pirte using it hard, even though I made a corner. That said, it's not good to take too much time just with a fountain pen. It's a troublesome place.

"I can't help but try."

The pen tip structure was taught to me by Surakutan, so let's try to make a shape first. "

“Do you make molds out of sand as usual?”

“Yeah, but it's smaller and more delicate than anything we've ever made, and we're going to have to make a number this time, so let's start by making something close to the nib, and then we can use it as a sand mold.”

"... what do you mean?"

"Every time I make a hole in the sand mold with the shape of a pen tip, it will subtly change shape, so I will make something to take the mold first.

So if you pour the metal into the mold, you can make almost the same thing every time. ”

I see!

"Well, first of all, I feel like I'll make it the way I've always been, and put the good stuff under the mold."

Got it!

I put out the furnace, put in the fire, made the molds... I tried to work as usual, but nothing went wrong that day.

In the first place, since the product is delicate, fine adjustments are also necessary for its division. No, I made an alloy of gold and lytium in the first place, but it seems to be too hard and subtle. It began with an adjustment. It was not very easy, but it was not something I could do in a day or so.

Especially when it comes to cartridges, there's no light at all.

In the simultaneous progress, I decided on the design and materials of the training bow, but as you can see from the name of training..., I had to make something like a folding bow, and it looked like a bow at the starting point.

I seriously regretted that I should have asked a lot of questions while Seydel was there.

While doing that, I headed north to the north, and about a week passed. Significant progress was made in both productions.

For the fountain pen, a certain shape was decided, and for the cartridge, the idea of replacing it like a cartridge was abandoned by adopting the opinion of Surakutan that it would be good to create a space to put ink in the hand-held part and pour additional shapes into it. In the first place, I couldn't possibly have such advanced technology, and I couldn't have done it from the beginning.

After that, we just need to prepare the nib, but to do that, we need tools to sharpen the metal. However, before I thought about this, Surakitan drew the blueprint for me.

It is a mechanism in which a propeller-like object is placed in a barrel, and the wind magic is passed through the barrel from the rear, so that the wind turns the propeller and the tip turns. As long as this mechanism is possible, the rotating tool will produce roughly the same thing.

There were a few things I had to think about, such as needing a Magic Stone Formation, thinking about abrasion resistance, and later replacing the material at the tip, but I also had to think about it and use it as a blueprint.

Besides, you've been thinking about them in between research. I don't know what to say... In a word, I took my hat off.

If I could get this far, I could do something with the triad error. Therefore, I was able to draw the path to completion.

When it comes to training bows, it's a little cheating.....

Among the names that followed us to connect Plitju with us, there was a person with something like a training bow, and they showed it to me.

It was simpler and less powerful than what we were trying to make, but it was necessary to devise ways to ensure that the materials used in the strings and the objects to be ejected were always subjected to the force of the strings, but the folded structure that was the best neck was perfectly understood. No, it's such a fine thing... let's be honest. It was a shock.

It's not malicious, it's just Respect... I want you to forgive me.

Incidentally, the string is going to increase in strength by using the hard thread obtained from the S rank monster, Arachne, to obtain stronger tension.

Of course, that amount of ruggedness is required for the main unit, but once you know the structure, you know where to reinforce it, and it is not a difficult task.

Also, about the pedestal on which the flying object is placed. If you just fly an arrow, you don't need such a thing, but in this case, you plan to fly various things, so you need to be able to adapt to any shape.

I think someone with good intuition will come up with it immediately, but by making it a leather or fabric pedestal, it can be deformed to some extent to the shape of the flying object. If you are aware of this, you can solve it by making the pedestal more durable leather.

In my case, I got this inspiration from a sling toy called a pachinko that I saw as a child. Indeed, the pedestal part should have been made of either leather or rubber.

It's a little crafty, but I was able to confirm the structure, so I just made it into a shape afterwards.

I need fine parts, but it wasn't that hard for me and Nil trying to make something as delicate as a fountain pen.

Furthermore, because there are rotating tools used for fountain pens, they can be processed more easily, so there were no other problems.

Incidentally, it's a grindstone used for rotating tools...

[Polysite... A mineral used in common grinding wheels. It is a mineral with high hardness, and microcrystals are gathered together, and many metals can be sharpened. It softens by cooling to below freezing point, and can be processed.]

That is, there was something that was made exactly for the grinding wheel, so we decided to process it and use it as a tip.

It seems that it softens when cooled, and there was an explanation from the beginning.

When you say it softens when it cools down, it feels strange, but it's slurred...

"Maybe, but by cooling it, the microcrystals shrink, creating gaps and flowing." I don't know what's going on with the bond between the crystals... but it's either an ionic or a magical story. At the interface of the crystal... "

So, you talked a lot, but when it gets cold, it becomes soft and can be processed... I can only understand it. I was also excited, and I thought it was a super unusual phenomenon, but I was convinced that it was a strange stone... The electrons come together like this and talk like... and you can imagine it, but heheheh. It's just about the level of understanding I can say.

In order to properly understand it, let's try to enroll in the Surat Than course...

Therefore, although there are various things, on the eve of reaching the city in the north, which is relatively less damaged, the fountain pen and training bow were completed somehow.

"So..."

"I got it!!"

Nil and I have a fountain pen in our hands.

"Oh! Congratulations! You did it!"

Surakutan, who knows the general flow, is honestly pleased that Nil and I have completed the fountain pen.

”Huh... that's a fountain pen... I wonder?”

Yes! It's you!

"Um... what's that name?"

"Master, please put it on!"

”Kei-kun...... Pfufu......”

"Surakuta, what's the matter with that laugh?"

Me and Nil's body strokes. Are you going to make a fool of yourself? "

"In other words, you can't be stupid!" That's why... fufu... "

"All right, get out there."

It's out here... but I won't allow anyone to make fun of you!

"That's a cute name."

That's a cute name!

"Eek?!"

After all, it seems that this sense is conveyed to Heine and Pilté.

On the contrary, Surakutan is surprised that Heine and Pirte's reaction makes his eyes pop out.

"Oh my God, you're so cute. I'll take care of you."

”Ka... I'm calling you... right?”

Is there anything uncomfortable about the name you gave me?

"Nil-san?! I'm afraid of something hidden under my smile!" I don't want to know! I don't want to know what's underneath?! "

Well then... I don't feel uncomfortable... right?

"Ahh, there's no such thing!" That's the only name I have! Yeah!! No! Shinya-san is the stone! It's a first-class product even with a sense of naming! Hahaha! "

"Fufufu. That's right. Master is the stone."
