Ye Xiao was a human, and a human's appearance inside the Underground Chamber of the Sky Pavilion was a big matter.
After all, what will happen if Ye Xiao turns out to be a spy from another similarly powerful force?
Sky Pavilion was a big force but it doesn't mean it is the only force in this Land. There are several such forces controlled by higher-ranked people of Holy Spirit Palace.
Human reputation was extremely bad in this Land for some reason. It was already very good that Spiritas doesn't treat humans badly, they treat humans equally.
However, the sincerity they showed humans is nothing more than a false display of emotion. Their wounds were still not healed and they consider humans the most disgusting creature in Chaos, just a single rank above Chaos Beasts.
Why?
It is because something must have happened in the past.
What?
Only Spiritas of this Land know.
