Fighting Confidently
Grey didn't head to the stage with thirty people there, the reason was that there were four Third stage Overlord Plane Elementalists there, and from what he sensed, they wouldn't be easy to deal with. Not just that, but the four of them seemed to be on good terms, so there's the possibility of them working together.
With that stage out of the list, he was left with the other two. One of these two had seven Third stage Overlord Plane Elementalists, while the other had six. According to the supervisor, eight people would qualify from this set, while only four from the group of thirty.
Grey surprisingly picked the stage where seven Third stage Overlord Plane Elementalists were standing. When the fighters saw him walking in, they all hardened their gazes. If they were ever told that an Origin Plane Elementalist would be able to make them this serious while they were in the Overlord Plane, they would never have believed the person.
