Low as his voice had been, Ergo still heard him and made his knowledge of Hal's words clear with his next words,
"Intricate how?" he asked.
Hal rolled his eyes and stood to his feet,
"Intricate in a way I really have no patience to explain to you. Just know that brute force will not get you through it. The Array is meant to test the strength of will. To test the knowledge of self of the individual within."
Although Hal spoke in a calm tone, he was actually preoccupied with thoughts that he kept to himself and kept off his face.
The Array would be testing a part of himself he had not been sure about thus far.
He had never shied from discovering what was deep within him but the fact of the matter was that all his attempts at learning who he truly was deep inside had all been unsuccessful.
Grimoire could not help him.
Hell, the stupid book could and would not even tell him what the strongest Dao was.
