"NO!"
Cenk's roar peeled through the dungeon, shaking it so severely that it seemed like it might collapse at any moment. But it was right then that the Runes activated.
Sylas had already noticed that there were D-Grade Runes that formed the dungeon. And yet, there were no D-Grades in captivity. Why was that?
At first, one might think that this was out of an abundance of caution. If it was before he had spent so much time with the UniForm Andromeda, Sylas might have dismissed that as well. In that case, he might think that the D-Grade Runes were mostly hollow and unimportant, causing him to neglect them—or at the very least, he wouldn't rely on them.
But his scope of the world had expanded considerably. He knew that the gap between E-Grade and D-Grade was enormous, a truly unfathomable chasm. The amount of effort you would need to upgrade so many of the materials in this dungeon to D-Grade was ridiculous.
