She's secretly wants it

@GalladeGuy You do remember how much crap they bought in the town, right? A lot of that was for stuff that inventor girl would need. Someone making things like she is would've needed copper for a lot of things. That's also just assuming the don't have any copper deposits elsewhere near the village. The only identified resource in that regard was the bauxite where the plane crashed. There's kind of a crap ton more land around.

Duralumin is an alloy of aluminum and copper. They explained where they got the aluminum from, but there's no copper in bauxite...

Even if those shields are made of aluminum they have to be somewhat heavy and just seeing the normal strength highschoolers carrying them like it's nothing just feels stupid. Also if they didn't have the proper equipment to handle that uranium somebody is sterile now.

The NTR prevention squad arrives. True heroes to self-inserts everywhere.
