The speaker was a man and was accompanied by two women who were also human.
All three appeared to be in their 30s or older. In terms of power, they were weak; they had less than 5,000 power, and the strongest person was one of the two women.
Matt looked at him for a brief moment and nodded. "What exactly does the pillar test? The purity of the mana?" he asked.
The man nodded at him in response. "Purity and concentration, the former being the most important with an importance of 70/30."
Matt nodded. 'As I suspected... But I'm seeing something in the patterns the pillar follows when testing one, and I feel it's testing something else as well...' He thought, though he sighed internally.
Neither he nor Alice had any way of knowing how pure the mana they controlled was because it didn't belong to them, to begin with. And if Earth knowledge can be used here, then Matt is sure that they are far behind in terms of purity.
