Nine-colored Beast Breath.
The top-secret cultivation method of the Great Yu Imperial Family, not passed outside their lineage, was also extremely difficult to cultivate.
Mutant beasts were the favored children of Eternal Night, growing strong on the mystical powers within Eternal Night. The Eternal Night aura created by the Nine-colored Beast Breath cultivation method was especially thick, capable of turning the practitioner into an ideal lure for mutant beasts.
This was akin to cultivators who absorbed the Essence of Heaven and Earth. If they sensed an exceptionally pure and dense Essence, they would likely suspect the emergence of Heaven and Earth Treasures and naturally wish to investigate.
Furthermore, mutant beasts trusted Eternal Night the most.
This cultivation method also required the influence of the Inheritance Stele within the Upper Cave Heaven of the previous dynasty to learn.
"Indeed, it came in very handy."
