The first person had died in the war, and it was Samuel, the former Junior Sect Master of the Eternal Fire Sect.
After Exar had killed Samuel, he looked at a specific person immediately.
It was Gravis.
Exar hadn't been under so much pressure that he couldn't spare any concentration, which meant that he had watched some of the other fights.
Exar knew that Gravis was incredibly powerful but seeing something was always different from hearing about it.
Gravis had killed a level two Star God with basically nothing.
He simply threw a needle from a distance, and the guy died without being able to fight back.
Exar knew that his teacher was supremely powerful, but he had thought that he would, at least, be able to come to terms with Gravis' power. After all, Gravis was weaker than Arc.
Yet, Gravis easily took care of a level two Star God.
Even more, his Avatar was currently fighting a level three Star God.
