"Oh, Ray. Are you here at last?" It took longer than I expected."

　The Guild's Warehouse... when Ray entered what was now a temporary alchemy laboratory, he heard a voice like that.
　Ray and Vihela both turn their eyes to where they hear their voices.
　There was a figure of Azimov, as Ray had expected.
　He looks very satisfied, perhaps because he was happy to be able to devote all his energy to his hobbies.

"If you look at it, it was Azimov who made the detector to search for Ambris this time."

　the success of making Ambris' detector heard in a carriage
　Ray was surprised when he first heard it, but it was no surprise that Azimov was able to find the remnants of Ambris and build a detector from them.
　At the very least, that's the kind of perception Ray had, and the actual situation in the warehouse probably wasn't that wrong.

"The death-size spear was a little too much for me, but the twilight spear is a magic item I made." It wasn't that hard to get out of there."
"...I think it's usually hard enough." But I'm the only one who can use it?"
"Oh, if I took more time, I would be able to adjust it so that others could use it. Unfortunately, they wanted the actual thing that could be used as soon as possible."

　As Azimov muttered regretfully, the surrounding alchemists looked equally regretful.

(Are they all of the same kind?)

　Ray's mind is filled with words like that, but now he thinks it's far from it.

"I mean, did you call me at this hour to make sure that the detector works?"

　There was some stupidity, but at the same time there was also a judgment that it could not be helped.
　Ambris is a top priority and must do something about it in guillem.
　That being the case, we need to see if it works as soon as possible... and if it doesn't work, what's the reason?
　And if it worked, the next task was to make it available to everyone else as well as Ray.

(I mean, if you think about it, that Vichela and I woke up, that is to say, did they stay up all night? ... No, it might not be surprising.)

　People whose hobby is their job must have no trouble staying up all night.

"Oh, yes," Now, will you give it a try?"

　What I was given was a magic item of a palm-sized.
　The shape is flat as if a crystal had been crushed.
　But there was a black fog in the crystal... like the remnants of Ambris.

"What a strange shape!" "And how can I use it?"
"If you will give me magic, I will do it." The black man in the crystal will move to Ambrice's side, and if you go that way you'll get to Ambrice."
"...what happens if there are several Ambrises?"
"It will show you the nearest Ambrice's place...."

　The slightly less confident words came out of Azimov's mouth probably because he hasn't actually tried them.
　This magic item can only be used by Ray, which is a form of hindering.

"I mean, you're telling me to use it said.

　As Ray asks, Azimov and the other alchemists nod.

"All right. ... Then I'll do it."

　When I tell him so, he casts magic on the detector in his hand.
　The remnants of the ambrice in the detector then slowly begin to move.

"Oh, my God!"

　All the alchemists watching it cried out.
　They must have been confident that it would work properly just because of the magic items they made themselves.
　But it wasn't really a test... it was just like a theory on the table.
　For that reason, it seems that the joy of seeing the magic item actually moving was stronger.

(Oh... this is how it works.)

　Looking at the magic items in his hand, Ray thinks with admiration.
　Through the flat crystal, the black mist was moving diagonally forward to the right.
　And in the flat crystal, it was gradually moving right diagonally from the front... really slowly, but directly in front of me.
　This means that the Ambris found by the detector is moving from right to left.

"Umbris is still running at this hour, after all." ...and can I take this detector with me? You use the remnants of Ambris, I mean, if I take this with me, I don't think I can make it any more?"

　Now only Ray can use it, but eventually other adventurers will be able to use it. Recalling what he said, Azimov nods back with a confident smile.

"It's not all the remains of Ambris taken from death-size or twilight spears. You don't have to worry because we've got a certain amount here."
"You've got it right? --so I can get this detector for you?"
"Oh! You're the only one who can use it, so there's no point in having it here. Well, it's possible to reconsider it for your reference.

　If the detector works, I can almost say I don't want you anymore.
　Ray gets a little irritated by such a conversation, but Azimov opens his mouth before Ray opens his mouth.

"There are death-size and twilight spears over there, so take them with you." Death-size was something I couldn't afford, but I've fixed the spear in the twilight in detail. Well, it's not like it's more functional, it's like maintenance."
"... weren't you busy with Ambrice?"
"Well, I'm sure I can do anything, if I'm not as good as this. Go faster than that. You still have something to do, don'

　Azimov turns away from Ray and tells him, but a female alchemist approaches him a little further away.

"Huh, Mr. Azimov, you look pretty good about Mr. Ray, because when I separated the wreckage of Ambris from the magic item I borrowed, I didn't let anyone else do it for me."
"Oops! Warsha! Don't talk about what you don't want, just come over here! We'll start working!"
"Wow! I know! Don't yell at me!"

　A female alchemist surprised by Azimov's loud voice... a woman called Washa goes there, complaining about Azimov.
　Then Azimov and other alchemists talk to each other about how to make the detector accessible.
　The alchemists are huddling together to express their opinions, which naturally makes Ray quiet.

"Do you think I meant to come?"

　mutter a little Vihela
　I was called at this hour to see if Ray could use the detector.
　In other words, Vihela had absolutely nothing to do, even though she had been woken up and brought to the guild in her sound sleep.
　just being there It wasn't quite convincing that we were brought to the guild at such a time to make things like that.

"But you would have gotten angry if you had only called Ray?"

　Ray and Vihela turn to a familiar voice from behind.
　There was Marina in her party dress as usual.Have you not yet slept as a guildmaster, or were you woken up early in the morning like the Rays?
　Ray couldn't tell which one, but Marina didn't look tired when she showed up.
　At such a marina, Vihela nods with a smile.

"Of course, right? If you want to call Ray, you have to call me, too."
"Then don't complain," --and I've only just come here, and as far as I can see, the detector didn't work?"

　Marina asks, looking at the hard-fought alchemists, but Ray shakes his head at them.

"No, it worked fine there. Now I know that the detector is working properly. Now it's a discussion to improve it so that it can be used by anyone other than me.
"... to be honest, I don't think it would be very useful to build a detector to find Ambrice, which appeared once three hundred years ago and has just appeared again."
"Yes, but this isn't the only place where Ambris appears, is it? If so, it can be used when Ambris appears somewhere else or something like that." And..."

　Marina, with a glamorous smile, looks at Ray's detector.

"It's not just Ambris that you can find with that detector, is it? Now you can only find Ambris, but what if you can find other monsters?"
"Don't make it easy for me to ask for subjugation."
"Yes. And we'll go straight to where the monster is, so we don't have to run into useless monsters on the way."
"That's... convenient,"

　What's hard about a request for subjugation is to defeat a monster to be subjugated, but most importantly, to find the monster.
　Monsters are often moving, unless they try to look for them in the way they sleep.
　Successful encounters with the moving monster depend on the adventurer's ability to chase and luck.
　But the success rate of the hunt will undoubtedly increase if the detector can tell where the monster is.

"...well, it will be a long way off before it actually becomes like that."

　Marina muttered, as if only Ray and Vihela could hear.

"Huh? Why? If this magic item can be used other than Ambris and mass-produced..."
"That's hard,"

　At Ray's words, Marina affirmed.
　Marina opens her mouth with a smile to Ray and Vihela, who look at her in wonder.

"Ray's detector... uses a lot of very rare materials to make it." It's not so much white as light."
"...really?"

　Worriedly, Ray turns to the detector in his hand.
　As far as flat crystals are concerned, they don't seem to be made of very rare materials.
　But in this situation, Marina is unlikely to tell a lie, which means that the detector in Ray's hands now is such an expensive thing.

"A light gold coin? ...I know you use something of that value when you make magic items..."

　It was the spear of twilight that passed Ray's.
　Many of the materials used for it are rare, and if you were to have an alchemist prepare everything for you without bringing in the materials, you would need enough money to make a gold coin.

(Well, if I were to actually buy the magic sword that Noise had used, I would make it a gold coin or something.)

　With that in mind, the twilight spear was made very cheaply by bringing in materials.

"You know what I mean, it's hard to mass-produce things at that price, and even if you can mass-produce them, there are a handful of people who can buy them."
"...how about lending it out in guilds?"
"I understand Vihela's opinion, but it's a little difficult. If this is at least a silver coin... no, it's worth a few gold coins, I think we can lend it out. I can't imitate lending you magic items of gold."

　It could be carried away, or it could be destroyed or lost in a battle.
　The guilds of guillums gather rare materials because of their geographical characteristics on the frontier.
　That's why they have more money than guilds in other towns, but that doesn't mean they're wealthy enough to throw away as many gold coins as they want.

"It would be a different story if we could make it a little cheaper." Anyway, Ambrice is the first priority over that now. I don't want to say that right now... but can I ask you if you can get out of town?"
"Oh,"

　Marina's words nodded, and Ray turned his hand to the detector... to the key to the killing of Ambris.
