"Perhaps it's something that's only possible in this place," Roan said in response. "They could match their spatial disruption with the flow of space because a flow exists, to begin with. Outside, there's no flow of space whatever. Space is static most of the time until experts at the Void Tempering Realm and above fight or something like that."
Rean had to admit Roan had a point. "That makes sense... the flow of space covering the disruption is a very likely possibility."
[Let's forget it for now. The creatures could jump off the swamp at any moment, so pay attention. We are very far away from our objective.]
Luan agreed with her. "Sister Orb is right. We've been moving for a few days already. But even though that's the case, the flow of space barely changed at all. That means the source of this phenomenon is really, really far away."
