Cain's eyes glowed with more and more power as if responding to the storm in the sky. To tell the truth, he was just as surprised as Horus to see that the type of Ego Destruction Tribulation he would trigger would be of such magnitude to cover the entire continent and whose power seemed to evoke the highest level of Aether.
He had been suppressing the Nine Ego Destruction Tribulation for over a year now, and he knew that it would rise to the next level after the enhancement to his Ego Wave, but this was simply too much, making him think something else was involved.
Of course, Cain did not show any of that on his face, as there was no room for doubt at a moment like this. His eyes were full of resolution and confidence, increasing the fear in the Depravitas while filling the souls of his warriors with courage and determination.
