So, Hill had no choice but to strive to find similar materials in Master Gilbert's materials library, and after slightly clearing some impurities, to make a flying disk with slightly better quality.
Even if it's ugly, he accepted it, at worst making it matte black, and making the cover slightly flatter… At least make it not look like a pot-lid for braised pork.
But, just because it's dark wouldn't mean he has to stuff himself into an iron box... At the very least, it should be Fine Steel.
Fortunately, this world isn't led to the point that even Spatial Magic can't be used, and refined steel... this thing is available with Ruth, and shouldn't be considered particularly rare... it's barely an acceptable material.
With seven rings, Gilbert can somehow expand a small room of 40 square meters from a large disk with about 10 square meters space.
Thankfully, it's a circular space.
