第１７５掘：魔剣の秘密 中章 (Part1)
**Dungeon Excavation 175: The Secret of the Magic Sword - Middle Chapter**
**Side: Kaya**
Everyone is stunned by Yuki’s words.
It’s no wonder; I’ve never heard of a weapon crafted using a Dungeon Core as a material before.
However, according to Yuki, its performance as a weapon isn’t particularly impressive.
Actually, I realized that when the sisters were using the magic swords during their experiments.
After all, my own flame magic is stronger. Yuki’s forced level-boosting is one factor, but I feel like the fundamental level of the magic itself is different.
While looking through the documents, I recalled the time of the experiment.
Back then, I had been summoned by Yuki and headed to the testing grounds.
Waiting there were the sisters, Zargis, the guards Ria and Jessica, and the four little ones.
"Oh, sorry for the wait, Kaya."
"…Don’t worry about it. I’m expecting you to make me some Inari sushi later."
"You got it. Leave it to me."
"Ah, Big Brother, me too!!"
"Brother!"
"Yuki-san, me too!!"
"What a cruel man. Only Kaya…"
Yes, Yuki’s surroundings are noisy as always.
I don’t dislike it, but since I prefer things quiet, I don't cling to Yuki much unless we’re under the covers.
Riel and the others find it strange, but I like this kind of distance.
"Yes, yes, I’ll make enough for everyone. Now, we’re working, so try not to get in the way, alright?"
"““Okay!””"
Yuki instructed the little ones and turned back to me.
"For now, we have observers. Is that alright?"
"Mm, no problem. I think it’ll be a good lesson for everyone."
The little ones have high levels thanks to Yuki’s support, but their practical combat experience is overwhelmingly lacking.
I believe it’s important to increase that experience, even if just a little. If my and the sisters’ experiment can be of use, we should take advantage of it.
"Hey, Yuki-san, is there no reward for me?"
Riel, who was also participating in the experiment, raised a protest from the side.
"Riel, you get a platter of sashimi later."
"Yay! I’ll do my best!!"
She’s such a cheap woman, Riel.
…Though I suppose I can’t really talk.
"And Tori, is steak fine for you?"
"Ah, yes. Thank you very much."
And Tori, she doesn’t assert herself enough.
There’s nothing embarrassing about loving meat, but she tries to act like a lady in front of Yuki.
Even though she howls quite intensely when we’re in bed.
"Now then, is the preparation on your end ready?"
"…Yes, that is fine."
"…Um, since we are using magic swords, perhaps the children shouldn't be so close…"
I had forgotten about the sisters, who were the main event today.
It seems neither of them has caught up to our daily life yet.
Well, that’s to be expected. Aslin and the others really do look like children.
Even though they have higher levels than us, they lose out in everything except experience and skill. I don’t think those two could do anything against Aslin and her group.
"That’s true. The ladies have a point. Let’s step back a little, shall we?"
"““Okay!””"
"“…”"
They obeyed quietly, but they still looked uncertain, as if just being here was a problem in itself.
"Alright, let’s begin. Here, take the magic swords."
Yuki tossed the magic swords he’d pulled from his Item Box to the sisters.
"!? Wait, you can use Item Box magic yourself!?"
"Of course I can. Don’t be surprised by every little thing. You’ve already realized the gap between us and you, haven't you?"
Yuki’s Item Box is indeed a rare skill, but it’s not as if it doesn’t exist on our continent. It just seems to be beyond "rare" on this one.
"That’s irrelevant. Do you feel anything different about the magic swords?"
"…Mist, let’s just quietly accept reality."
"…Yes, Sister."
As instructed by Yuki, they swung the swords and generated small amounts of flame and water.
Hmm, it seems they are activating magic using the power of the swords while consuming almost no mana.
It’s a different type from Ria’s weapons and armor.
Ria’s Hero equipment only activates after absorbing her mana. The weapons and armor we’ve been given are also updated to run on our own mana supply.
I suppose this is like those electric lamps being developed for civilians that light up without needing mana. That might be a strange comparison, but I think it’s accurate.
"There are no particular issues. However, since you mentioned an experiment, I thought the magic swords might have already been taken apart."
"Indeed. There seem to be no problems."
"Good. Then the experiment is fine."
"That is fine by me."
"Alright. Then first, show me some of your specialties with the magic swords. You don’t have to show me your ultimate techniques; as fighters, I know you don’t want to reveal your trump cards."
Yuki stepped away from the sisters.
Unexpected. I thought he would jump in and strike immediately.
"Could you please not glare at us like that? We are well aware that we are prisoners."
Knowing we were looking at them with sharp eyes, they made a show of not doing anything.
"…We are just keeping watch. It’s natural to be glared at."
I retorted to Olive.
What a ridiculous thing to say after you were the ones who started the war.
Personally, I hate people who start wars for their own selfish desires. It reminds me of Loire.
"Just endure it. You started a war, got caught, and you’re still in one piece. You haven’t even been assaulted; it’s better than your own army, isn't it?"
"…"
"Sister, it cannot be helped."
They didn’t deny it.
Hmph, just as I thought. Even if they say something, they lack the power to back it up.
Yuki doesn’t resort to torture unless it’s absolutely necessary. Or rather, he doesn’t want to go through the trouble.
After that exchange, the sisters showed us their techniques with the magic swords.
"Wow, that’s amazing!!"
"Brother, do you want a weapon like that too?"
"Hmm, hmm."
"…The weapons Yuki would want are probably much more vicious."
The little ones were cheering and making noise while watching the sisters, but for us, who were gathering information while on guard, it was a mixed bag.
As of now, there’s nothing that exceeds the level of our magic.
The advantage is that the mana required for activation feels incredibly low.
As I saw earlier, the mana consumption is overwhelmingly lower than when we use magic.
Since I can see the flow of mana with my Mana Perception skill, I’m certain of this.
