This battle had tempered Gravis' Will-Aura only marginally. He had been in real danger when his opponent attacked first, which had increased his Will-Aura by a little bit, but everything after that had been inside Gravis' control.
Right now, Gravis' Will-Aura was still at the level of a Late Minor Circulation Immortal King's, but it was about halfway to the next level.
'Not even an increase of one level. Truly disappointing,' Gravis thought.
Gravis would have wished to get more tempering out of his opponent by telling him that Formation Arrays and poisons didn't work on him, but he didn't have the luxury right now. He had been able to do that with Samantha only because it had been guaranteed that no third party would intervene.
