Negris acknowledged: "A magic array is a very precise construction. Every inscription, every energy circuit, every structure has to be exact or it will fail. If the ground is uneven, the normally straight energy circuit and inscriptions would be distorted and, of course, it would not succeed."
"Oh, are there any magic arrays that are originally curved?" Luther asked.
Negris gave him a glance: "You mean to ask if there are magic arrays that don't have to be straight to work, right? This is a typical layman's question. Of course there are - curved ones, three-dimensional ones, layered ones... but flat arrays are the simplest. The simpler the structure, the less likely it is to make mistakes, and the higher the safety."
"Oh~ So the world transfer stations would rather raise a platform to make it flat for safety's sake, right?" Luther drew a conclusion and understood.
