Robin moved his eyes between Elizabeth, Victoria, Old Gu, and the other top-level Sages standing around him, then asked out of nowhere, "You all know now that those lightning bolts can pierce the dome, right?"

Everyone nodded, this was one of the things that mostly crush their confidence, if only those attacks were outside, they simply wouldn't come out, they could probably stay inside the dome and strengthen it until they find a solution, in the end as long as they had a safe haven they would be able to negotiate with those creatures even if it took months or years! ...But reality had a different opinion.

"Some of you may have noticed that all of those killed by the lightning bolts were low-ranking Sages, and all of those who were attacked were all flying, right?" Robin asked again

"This…" Some of them asked and looked around, while others nodded.
