It wasn't just these demons revealing their true forms; at the very front, there also stood over a thousand demons in various attire, who had transformed into human shapes. The only thing that differentiated them from humans was a pair of unique vertical pupils. Of course, if observed more closely, one could also notice that their facial expressions were significantly more twisted than those of normal humans.
Demons capable of taking on human form must be at least on par with the Martial Arts Grandmaster Realm, and are thus Eighth Grade demons. This would mean that every single one of the over a thousand demons present was above Eighth Grade. How many were Seventh Grade, Sixth Grade, or even equivalent to the... Fifth Grade demons of the Yin Yang Holy Realm?
