Chapter 300 – Big-Sisterly Disposition?


“Hmm… I really don’t know if that was the right thing to do.”

I said this in the carriage on the way back from the merchants association, closing my eyes and turning my head to the ceiling. I could see myself wrinkling my brow.

“What, do you have a problem with me?”

“No, I don’t have a counter-argument, but in the end, we give them the money and let them work out the details, right?”

“You see… we are royalty and those who are related to royalty. Our role is to give discretion and budget to those who can do the job. If we, who have the power, interfere, even if it is a poor plan, the subordinates will have to obey, right? As a result, the work will be delayed, and the results will be poor.”

“That’s a good argument… but my mentality is basically that of a subordinate.”

“Then be more elegant. You’re going to be a part of the family.”

“Elegant, huh…?”

I turn my attention to Iphrita, who is sitting next to me and looking at me with strong-willed eyes. Iphrita is a bit of a disappointing girl who wears red jerseys in private just because it’s easy, but when she wears dresses and ornaments like this and looks sharp, she certainly looks elegant or even noble.

“What? Do you have something to complain about?”

“No, I’m just admiring the noble aura you exude, Iphrita-sama.”

“What’s with the way you’re talking? It’s disgusting.”

“Don’t call me disgusting so casually. You’ll make me cry.”

If a beautiful girl like Iphrita says that to me, my glass heart will get cracked, so I really want you to stop.

“Don’t do it, okay? If I make you cry, I’m afraid of a lot of things that will happen afterward.”


I can think of at least three people who would grow horns on their heads if I cry, or rather if I mention that Iphrita made me cry. One of them is someone who has had horns like a devil from the beginning. The other two are her sister, who doesn’t look like a sister and her mother. The others are the harpies, who are probably still guarding this carriage.

The way they treat me is becoming more like an object of worship than a husband… I may have to do something about it soon.

“No, let’s put aside the talk about being afraid of me crying, shall we?”

“Yes, yes, you want to do something to help because you’ve been left out of the situation lately, right?”

“No… Not that it’s wrong, but…”

It’s true that I’ve been left out of the discussions with the Holy Kingdom lately, and I’m bored because I have nothing to do. How should I put it? Be a little gentler!

“You don’t have to work so hard. Just drink from the morning with elegance, and switch from one person to another, whether it’s Sylphy, Mother, Dri-aneesama, or anyone else, and just enjoy drinking. You won’t have any trouble finding a partner, will you?”

“Aren’t your words a bit harsh?”

“Not at all.”

Iphrita turned her face away from me as she said that. No matter how you look at it, it’s not like it’s different.

“Well, let’s not talk about that right now. You want to work yourself to the bone, don’t you?”

“Yes, yes.”

“You don’t have to work, but you still want to work? I don’t get it.”

“Because I don’t have it in me! I just don’t feel comfortable doing nothing at all!”

“If that’s the case, why don’t you just develop weapons or golems or whatever you want? I heard that. I heard you had a golem hidden away that could overrun a country’s army.”

“I’m stuck in that area.”

I can’t seem to find the end of the golem workbench. I’m sure I could make even more useful tools if I upgraded, but most of the level of goods I can think of can be made at the golem workbench. It’s the materials and ideas that are the problem.

“How are you stuck?”

“I can’t find the right materials to make what I’m trying to make, or if I have an idea, it’s hard to get them. I also have a few things that I can’t make because I don’t have the knowledge to do so.”

“You should inquire with the Adventurers’ Guild about searching for materials. They have samples of monster materials and special materials found in remote areas, and they will procure them for you if you ask them to. If you become a client, they will bring you newly discovered materials when they find them.”

“Really? Should I ask the coachman to head to the Adventurers’ Guild for a while?”

“No problem. It can’t be helped, so I’ll go along with you like this. And if you don’t know enough, you should study.”

“No, there is no way to study here.”

The knowledge I lack is the knowledge of science, electronics, and military weapons from my former world. There are many things that I am vaguely aware of but don’t really know much about. For example, knowledge of railguns and laser weapons is at the top of the list.

I only know that a railgun uses a magnetic bullet body placed between two railguns and that the Lorentz force is somehow generated by a tremendous amount of electricity to fire the bullet at ultra-high speed. When it comes to the principle of laser weapons, I only know enough to burn or explode an object with a high-power laser.

To begin with, even my knowledge of lasers is vague. I think I heard something about coherence, but I don’t know what coherence is in the first place. I am at that point now.

I have deepened my knowledge of the canned goods, guns, and bullets that appeared in survival-type games by researching them on the Internet and, in some cases, buying and reading specialized books, but my knowledge of things that fall into the realm of science fiction is not that deep.

Even now, I’m cheating a lot with the golem core when it comes to controlling air boards and golems.

“Ah, you know, the chemical or whatever it’s called. But that can be substituted with magic or magic tools over here, right?”

“That’s true.”

“Then why don’t you study magic and magic tools? I’ll teach you, okay?”

“I see…”

I think what Iphrita said makes sense. If I can’t do anything with my current knowledge and can’t make any further progress, then I should reach out for new knowledge.

“The problem is that I have no magic at all.”

Yes, I have no magic. I have no magic power at all. I can’t feel magic. I have absolutely zero background in the magical power necessary to manipulate magic and activate magic tools. I am unable to use any magic tools other than those that have a built-in energy source, such as magic crystal stones.

On the other hand, there is the advantage that magic and magic tools that interfere with magical power and bring disadvantages to the target do not work.

“You can deepen your knowledge as much as you want even if you don’t have magic power. I’ll take care of the part of you that can’t handle magic.”

“Is that how it is…? Can I ask you to do that for me?”

“Leave it to me. I’m sure that teaching someone from scratch will be an opportunity for me to deepen my knowledge as well.”

Iphrita proudly boasted. At first, I had the impression that she was a bit tough to deal with, but now that I’ve gotten to know her, I can see that she’s a very caring person; she might indeed have a big sisterly heart.

“Once you’ve decided that, the Adventurers Guild should be the first place you go.”

Speaking in a good mood, Iphrita opened a small window at the front of the carriage and began to inform the coachman of the change of destination.

The idea of using magical knowledge instead of scientific knowledge to innovate technology… had been around for a while, but I had basically left it to Isla and the others. Now I’m going to get some magical knowledge myself and apply it in a variety of ways.

“Best regards, Sensei.”

“Sensei… Yeah, I’m Sensei. You can call me that from now on.”

Sensei, your nostrils are getting bigger. Iphrita looked like a high school girl in human terms, and from my point of view, she looked younger than me, but in reality, she was older than me. Even Isla and Aquawill-san are older than me.

“What’s with your eyes?”

“No, I’m just looking at you thinking you’re older than me.”

“What? It’s obvious, isn’t it?”

Iphrita looked up at me, tilting her head with a curious look on her face as if to say, “What is this guy talking about?” No, from my point of view, she looks completely younger than me. Mr. Floyd of the merchants’ association naturally treated Iphrita as an older and superior person, but it is quite difficult for me, coming from a world where long-lived species did not exist. I can’t help but make a lot of judgments based on appearances.

“So, what kind of material are you looking for exactly?”

“Oh, let’s see…”

Then I continued talking with Iphrita about the materials that the Adventurers’ Guild handles.

  1. “When it comes to the principle of laser weapons, I only know enough to burn or explode an object with a high-power laser.”
    He also needs various flat and curved mirrors and semi-transparent mirrors for bouncing the laser beams between them, if I recall correctly. And various lenses too. So better try developing precise glass-working industry if he is still anxious about being irreplaceable in the future.


  2. I can imagine that you can shot a railgun bullet by using tons of electricity to super charge it with either positive or negative charge. And you keep the bullet in place by using a magnet with the opposite charge. When you want to fire, you just switch poles. This will cause a repulsion


    1. In a sense that’s how it works, but many times along the length of the rail as the bullet travels through it, the polarity and magnetic field switches and keeps pushing it forward.
