Are you really sure?"
"That I do not know. We cannot carelessly believe a weaselfolk magician, but upon completion, we promised to teach them the way to manufacture Blue Steel. Those greedy bunch should not miss that opportunity."
Geh, weasel again huh.
I'm slightly intrigued with that Blue Steel thing, I'll help them a bit.
I'll leave Mia to take care of the girl, and use [Telephone] magic to connect to Boruenan forest.
『Aze-san, could I have a bit of your time?』
『Satou! Of course you can.』
『Are you familiar with this gem called Blue Crystal?』
I asked about the Blue Crystal to Aze-san who sounded a bit lively.
Of course I'm talking in my mind, so the surrounding people can't hear it.
『Yes, I know about it. If I'm not mistaken, it's needed for Kobold's child raising isn't it?』
『The Kobold's mine has been exhausted, so they're in trouble. Do you know what kind of place this Blue Crystal occur at?』
『Umm, let me see--it should be deep in Mithril veins. I think you can get them along the deep part where the Dragon Vein is thick.』
I got to hear more detailed information than I thought, so I thanked Aze-san along with loving words and then I cut the call.
I don't know where this Dragon Vein is located, but since it should be connected to Sources, I'll check the core of towns and cities.
After checking Muno Earldom, I found out that there was an ore vein in the town where the monsters had build their nest.
There's a Mithril vein about 1KM deep under the city, and there are Blue Crystal along the crevices there.
That town is in a mountain district located between the hidden village of the giants and the Kobold town.
While I was at it, I tried searching the Mithril vein in the black dragon Heiron's mountain and the one in the dwarf's Bolhart dominion, I only found the Blue Crystals in the former.
The easiest way is to tell the Kobolds about the Blue Crystal in the Black Dragon Mountain which also means driving them away from the territory, but taking the profit for Muno Earldom into consideration, it'll be better if we gain allegiance of the Kobolds who hold the technique to mine and refine these special metal and also let them mine and refine the Mithril vein.
I call Arisa in Muno Castle with [Telephone] magic, and tell her to match the information about the ore vein.
"Satou."
Mia who looks like she's about to cry clings to me.
There's a desperate Kobold girl behind her.
That reminds me, I let Mia to handle her didn't I.
"Satou-dono, I beseech you! Send us to Boruenan forest with your airship. We will give you Kobold's treasured sword, 『Blue Fang』 as a reward for your assistance! If you so desire, I will make a promise to teach you the method to manufacture Blue Steel."
"That manufacturing method sounds attractive. However, we're currently in the middle of an official duty. We will help you obtain the Blue Crystal after we've accomplished our duty."
"Are you sure?!"
I assuredly nod back to the girl who's half in doubt.
