Recalling the earlier question

The gap widens further between a cultivator at the eighth stage of the domain realm with someone at the ninth stage even if they seem to be just one level apart. That gap was wider than a first-stage domain expert and a sixth-stage domain expert.

Ten eighth-stage domain experts would likely have half of them die before they forced an injury from the ninth-stage domain expert. Of course, Yang Qing did hear there were exceptions, there were specific individuals who could bridge that gap because of their domain, but even then all they could do was force a draw or perish along with the cultivator.
