"How is it? Is there really no way to pick up Joshua's signal?"
"There's no use—the distance is just too far…"
In the Piroth Galaxy, the edge of the cosmos—at the center of a huge Void observation array that had been set up temporarily, the tired Rune Master Barnil shook his head at a group of Legends and divine beings. "It really isn't a problem with our technology," he said rather reluctantly, "but he…has already left the furthest distance for Void observation. Don't you get it? It's similar to how we basically cannot encounter entire cosmos from the Void—it could never be observed even if we build another observation array a hundred times larger than this one."
"At best, we could laterally determine Joshua's situation by observing the movements of the Evil God horde—in other words, by watching the changes in that darkness of the Void."
