A day after the audience.
We need most of the students for the barrier creation, and those students need to be able to use chantless magic.
Even though the teachers have gotten used with chantless magic lesson, teaching all of them in one week will still be difficult.
Well clearing the dungeon would take some time, so today's main objective is teaching Ruli and Alma magic.
"Alma, you can shoot 【Simple Mana Enchant】 without a problem right?"
"I can do it with my eyes closed now! I mean I've shot like hundreds of it!"
"Then, the next one is 【Wire-guided Enchant】. Alma, try using 【Simple Mana Enchant】 but stop before you shoot it."
"Un!"
Alma put her mana on the arrow she readied.
The range is only about 3 meters.... It's good enough to get the feel.
"Then, try to make the arrow curve to the right using that thread as an intermediately...."
"Oooh, it curved!"
Alma's arrow slightly turned right.
It should be optimum for her practice.
This means she'll be a bit away from us, but I can sense if she's in any danger with 【Passive Detection】 as long as she's in the same floor, so there's no need to fret.
However, unfortunately, augment magic isn't the thing I'm going to teach her now.
"Augment magic.... Or rather, first we need to make the materials for it. You should make your own weapon if you want to do augmentation."
First of all, if a First Crest bearer needs to bring a sword whenever they want to practice, they will never have enough money on them. If they can create their own sword, they can practice anytime they want.
However, it isn't that difficult if it's only to surpass the swords you can find in the present royal capital.
"Well, I'll teach you weapon creation later, first our problem is.... procuring the materials. In short, metal refinery."
"But first, we'd need ores to refine--"
"We have raw ores here. This."
While saying that, I take out a sword from storage magic, put 【Mana Strike】, and 【Brittle Fracture】 on it and hit the dungeon wall with the sword.
By the way, 【Brittle Fracture】 is a magic to raise offensive power against hard brittle things like rocks.
"Dungeon's wall have a moderate amount of metal in them. There's many reasons for that.... Well, just keep that in mind for now."
"Eh, you're breaking that!? Or rather, you can break that!?"
"Hm? Isn't dungeon's wall a resource?"
"Let alone resources, it should have been the forefront of things that absolutely can't be broken...."
But it can be broken though.
Well, no point thinking about it. It's probably another weird knowledge the demons spread. Those bunch really never do anything decent.
"I'll teach how to break the dungeon's wall later, for now let's focus on refinement. I'll show you how to do it right now, so watch closely and keep using 【Passive Detection】."
"Yes!"
I pick up a huge lump from the crumbled wall while Ruli is watching.
And then I crushed it into pieces using the sword with 【Brittle Fracture】.
"What do you think? Did you get it?"
"It felt like the mana melted the dungeon wall somehow.... Was that how to do refinement?"
"No, this is the second stage."
I activated magnetic magic and gathered black lumps from among the broken pieces.
"These are the dungeon's crude ores. Well, put simply, they're mix of metals contained within the dungeon wall."
Dungeon's crude ores contain iron within it so you can collect them using magnetism.
The secret here is to put in a largish amount of mana right before they melt. The melting point will become lower if you do, making it easier to melt the lump.
I cooled it with water magic lastly, and recrystallized it using mana again by the same method like earlier.
The blue is mithril, the gray is iron. It seems the metals mixed within the wall in this floor are mostly of these two variants.
"How about it?"
"Don't tell me that's.... Mithril!?"
After identifying the blue parts on the lump, Ruli asked me.
"Correct. The gray one is iron. ...But the purity is lacking, thus we need to raise it by repeating the process before."
Afterward, I broke the spotty lump, melted the blue pieces and the gray pieces separately and recrystallized them again with the method earlier.
Recrystallization is needed to remove those impurities.
To be honest, I thought it would have taken around two hours.
Should I say as expected of the school's runner-up, or maybe it was thanks to her intense determination....
