The flying birds among Demon Cultivators possess strong sky-controlling ability.
Regular Demon Cultivators also have Sky-jumping Technique.
For Martial Artists, those in the Spiritual Martial Realm still need Lightweight Skill.
In the Black Tortoise Realm, one can fly, but without special techniques, the physical sky-controlling is far less free than that of a Cultivator.
In this regard, Martial Artists are at a disadvantage.
However, this place is the Celestial Essence Realm.
In the Celestial Essence Realm's local warfare, Demon Cultivators won't send down Transformed Demon Emperors and Celestial Demon Realm unparalleled experts.
Given their previous understanding of the Celestial Essence Realm, even sending several Demon Body Realm Demon Kings is considered respectful to Celestial Essence Cultivators.
With world limitations, they can at most dispatch Demon Body Realm Demon Cultivators.
Unless they become enraged and want to completely destroy the Celestial Essence Realm.
