Even though Paragon Masters were comparative in strength, there were still differences between them.
The stronger Paragon Masters were existences that unparalleled existences could not kill. For instance, Southern Cloud King, Great Paragon Fuyi, Sky-Rending Great Paragon, Black Devil Great Lake's chief religion master, 'Yama Religion Master'. Only then were they qualified to be absolute overlords of Realm Heart Great Land! Unparalleled existences did not dare to hold any contempt for them; they dared proclaim themselves as rulers of a region. And the reason why some devils from the Black Devil Great Lake were not afraid of bringing chaos to cities within the Summer Wind Ancient Nation was all because of Yama Religion Master.
