This group of living beings from Hell had a natural hatred and disgust for cultivators of the medium chiliocosm.
Fortunately, in this generation, the Martial Dao Prime Body held down Hell. With the help of Consort Yu, he subdued and tamed this ferocious and bloodthirsty Hell Army.
Otherwise, if such a Hell Army suddenly descended and was completely uncontrollable, it would be a huge disaster for the medium chiliocosm!
The Martial Dao Prime Body had secretly brought living beings of Hell who had a chance of entering the Emperor realm like Hell Lord Bitter Springs to the Great Wilderness World through the Hell Gates.
After all, the Hell World was comparable to the medium chiliocosm with many experts.
It was only because the Hell World was incomplete that these living beings of Hell were suppressed and could not advance to the Emperor realm for a long time.
