The last level he observed was that of the leaders of the two sides.
While the leader of the other side didn't have anything in particular to be pointed at apart from a stronger body, he noticed the red third eye of the Garsan leader. That characteristic was different from the other Garsans he had met in the bubble.
But when he thought back, during his time in his cell on Gars, there had been some that had that characteristic. Maybe it was the result of their level, a consequence of their way of cultivation or a racial consequence.
No matter the reason, that leader had a stronger output of fire, a more versatile control, and her stamina was better than the rest, a reasonable evolution with a higher level.
