So, I went deeper into the cave and found a hole in the wall and a room.

Is that the source?　What was in there?

　The next morning, I was sitting at a table in the charcoal shop, reporting to Mr. Gaither about yesterday's events. It was supposed to be used for business meetings, but it seemed that all the customers at the charcoal shop were regulars.
　I've never seen it in use.
　My first thought was to go to the Tankokai, but upon reflection I realized that I didn't know where it was.
　I had no choice but to go to the charcoal shop, where I was immediately summoned.

"A lantern, a human bone, a sword, and a report. I defeated a demon on the way, is there any problem that the loot is mine?

The room is not mine, by the way, so the contents of the room are yours as well, since you are only paying to rent the coal mine, which is common property.

　Mr. Geinta thinks for a moment and then replies.
　So that's it, I've got your word for it. I take everything out of the item box and place them on the table.
　The wisp core is also there.

"I've never seen a sword like this before, it's rather slender but the blade is long, I feel like it would break if I swung it hard enough, is it for poking or something?

I don't know, but it seems that the sharpness improves when you pass magic power through it, so I'm going to use it from now on.

　I didn't see how sharp it was before I passed it through the magic, but I'm pretty sure that passing it through the magic had some effect on it.

In the event that you have any questions regarding where and how to get the best results, you can contact us at the web site.　I'm sure you'll be able to find something that works for you.

　Then Mr. Gainta cut off his words.

"Hmm, ...... a paper report and a nice ...... artifact?

I think so, the performance of this sword is beyond that of any other sword, and this report is also written in a different language.

　He pointed at the report. As I flipped through it, the paper didn't seem to have deteriorated much. It might be like Japanese paper.

Can I have a look?

　Without asking for an answer, Mr. Gaither turns the page.

"I don't know the language. ...... Wait a minute, you just said "report", how did you know this was a report?

"Oh, .......

　That was careless. I could read it so naturally that I completely forgot that I originally couldn't even read the title.
　It would have been better if I had lied about it, but I guess it's too late now. I'll give it a try.

"Well, the format of the report is similar to the one I know...

The format of the report is similar to the one I know." "You stuttered for a second there, and how do you know the format if you can't read?　It looks like a diary, except that it's written on paper in characters I don't know.

　I dug my own grave. You're right, it's just the date, the weather, and the contents, exactly the format of a diary.
　No choice but to be honest.

"Yeah, I can read this, sure, it said something about dragons, but that doesn't seem to be a concern anymore.

If it's an ancient language, and it turns out you can read it, you're going to get recruited by countries, and if you refuse, or even if you don't, you're going to get kidnapped by other countries. If you refuse, or even if you don't, there is a rather high probability that you will be kidnapped by another country.

　A high probability? And I'm the one who revealed it, but you're the one who exposed it. I did try to hide it.
　But wouldn't it be better for Mr. Geinta if I was kidnapped? Mainly in terms of patent fees.
　Well, I'll take that as a favor. If he sells the information to the government, I'll be laughing my ass off.

"Yes, I'll do that.

I don't know about the sword, but the lantern is not that rare of an artifact, it's probably the most common artifact, but it's original and has high performance, so if you don't need the money, you can use it for your adventures.

　I'm not sure what to do with it.

"By the way, how much would you get for it if you sold it?

You could build a house of some size in King's Landing, though it wouldn't be inside the inner walls.

　That wasn't a mistake. The artifact was indeed of a different class.
　What is this wisp core anyway?　Let's just say it's a black stone. I won't make the same mistake twice.

By the way, what is this black stone? It came from a black demon that suddenly appeared while I was exploring the room.

"Artifacts and black demons?　You're not going to tell me it's a wisp, are you?　It's not something that can be defeated by an individual, and it's most likely a demon that wandered in from somewhere else, right?　What did it look like?

"Well, ......, it was a blurry, six-legged demon that didn't work with swords or magic.

...... You're lying, right?　I don't know how many legs it had, but black and blurred outlines are famous characteristics of wisps. ...... So maybe this black stone is a wisp magic stone?　If so, you could build a castle out of it.

　A castle? ....... I've got another bad one. There are more and more reasons to be targeted by the government.
　What if the country's spies or something are listening in on us around here? There's no soundproofing equipment here.

"What is the Wisp Stone, and is it strong?

It's not strong on its own, but when you use an offensive magic tool, you can use a wisp magic stone to store magic power, and it can be used to defeat wisps.



　Maybe it's like a magical version of a headphone amplifier?
　Or maybe it's like a fission bomb that fuses hydrogen with .

Uh, by the way, how do you properly defeat a wisp?

I don't know much about them, but I've heard that you can use an artifact boosted by a wisp core to freeze the air. By the way, how did you beat it?　If there's another way to do it, it might be a great discovery.
　Freeze them with air, and they die. Something like that.

I beat him to death with my bare hands.

"Mm. ...... I don't think a wisp would die from that. ...... But when the wisp's burn marks were found, I'm pretty sure I heard that the person who found it collapsed from magic overload, if that's what happened. Is that the cause?

　The wisp is likely to be a mass of magical elements.
　But this is a bad story.

"If this gets out, I'm afraid I'll be hounded by all sorts of people, so can you please keep quiet about this ......?

"Yeah, I'll keep my mouth shut, I'm not going to betray the trust you gave me.

　Yeah, thank God you're a good guy. If Mr. Geinta was a bad guy, I'd be in a basement somewhere reading aloud from an ancient text in a week or so. At best, I'll be careful on the streets at night.
　I don't know what I should do if they come at me head-on, wielding the power of the state. I'll practice the fast-moving wind magic that Magus used.

That's all I have to report, is there anything else you want to tell me?

No, not really, if the mines are back to normal, we should be back to full capacity within a month, maybe more depending on demand.

By the way, how do you plan to sell the coke?

"We're offering some free to customers of the charcoal shop and looking for buyers. The production system isn't quite up to snuff yet, but it's already starting to sell like hotcakes, or rather, there's a lot of competition for this high-performance blacksmithing fuel.

　It's a little bit different from the original plan, but it doesn't matter as long as it sells.
　I hope they will take it to their hearts' content and raise the reputation of coke.

"Okay, I'm planning to leave town when I have the weapon, but I'll come back to collect the patent fee when I'm free.

　I'd like to see what you've got. It's a shame to stay in one place when you've come to another world with the power of non-death.

You don't have to do that, there's a 10% tax and fee deducted from the patent fee, but that includes services that can be received at other branches, although you need to tell them in advance that it will be expensive.

　I didn't hear that, fees. I'm not asking you.
　The Adventurer's Guild doesn't charge taxes, but I'm sure they're deducted from the beginning.

I see, so I can pick it up on the road.

"Outside the country, the guilds of each country are half independent, but they are connected to each other to a certain extent, usually you can deduct the money, but in your case it would be better not to, you know why?

　It's a patent that can only be used domestically. If you don't release it to the rest of the world, it also means you can't get support from outside the country.
　Other patents also seem to be one-to-one, so there may be many cases in which foreign countries do not matter, but if the patent is explicitly closed only to foreign countries, it is still a different story.

"Okay, for now, you can keep my share of the investment until you don't need the capital investment anymore, although I may tell you if I need the money.

Thank you, that's what I'll do.

I'll leave you to it.

　I leave the charcoal shop and head for the weapon shop. I wouldn't be surprised if it was finished today. I also want to know about this sword. After all, a cake is a cake maker and a sword is a blacksmith.
　When I entered the workshop, I saw Mr. Sumizu nearby. He doesn't seem to be busy.

"Excuse me, I picked up a new weapon along with some artifacts during my adventure, could you show me what it is?

"Sure, I'll take care of it. Let me see.

　I took out my sword.

I took out the sword. "It seems that the sword can be strengthened by passing some magic power through it.

　As I was saying this, Mr. Smith yelled at me.

Put that weapon on the ground right now!　Put that weapon on the ground right now, and then we'll talk!　It's dangerous!

　...... What, is this dangerous?　I'm not sure if this is a cursed weapon or not.
