Draco smacked his lips. Since his accumulation of top-grade Aether Crystals made him into a bonafide silk-pants young master, he didn't have to think long about it and just bought them all. Some of these devices were bound to be useful. He was especially eyeing that exothermic device, which was just fancy talk for a bomb.
He had always wondered how the Goblins and Gnomes were able to craft those contraptions of theirs. With his current knowledge, it wouldn't surprise Draco if they simply turned out to be like Master Rank Magical Engineers. Perhaps he should visit them after this Unique Quest was done. If his theory turned out to be right, the wealth of their items and skill might surpass his prior estimation.
