Ren didn't understand the reason for the unexpected question but shook his head.
"Not completely yet," he admitted, "but my beast can tell it's connected to the tower internally. As long as it's connected to the mana flow from the vein, it can't be eliminated with outside force..."
He paused to send a pulse of purifying light that disintegrated a creature that had slipped into the defense by launching itself from the ceiling.
"Unless we made a direct attack on its network," he continued, "which I could do with my beast's characteristics, but it's impossible to damage the enormous corrupt crystal network at my Silver Rank. It has too much accumulated energy, maybe if I were Platinum Rank like you..."
Ren increasingly understood the scope of the purple network, and could now feel how the abyss beasts rose from the depths to join the transformed ones in the attack, in incredible quantities.
