Artic didn't think Lancel would use such a thing. Artic had spent a short time at the Brion and Void Center but had obtained a lot of information.
As he learned, although "Precious Weapons" or "various treasures" were not generally used at Origin Level, they were used directly by people at the Stairum Level and peak level like himself.
Some of these weapons were powerful enough to destroy planets, even stars. Artic understood that Dimension Rock, the stone he is now seeing, was one of those weapons or more likely a treasure.
He didn't have a general knowledge. No one knew where to use such things, commonly referred to as treasure.
Because in general, in most of treasure, there was a law on which they proceeded. For example, the stone that Lancel is currently using was referred to as a Dimension Rock .
