Furthermore, the Heavenly Jewel Island Skill Storing Palace had a strict rule in place. For the Heavenly God Stage Heavenly Beasts, even the direct bloodline of the Heaven’s Expanse Palace had to reach at least the Heavenly King Stage and above, and be given permission by the upper echelons of the Heaven’s Expanse Palace before being allowed into try Skill Storing on them. No outsiders were actually even allowed to enter that portion of the Skill Storing Palace.
In the entire mainland, Heavenly God Stage Heavenly Beasts were extremely rare, though perhaps not as rare as Heavenly God Stage Jewel Masters, it could still be described as rare as the feathers of a phoenix and the horns of a qilin1. To even find a Heavenly God Stage Heavenly Beasts was something so rare, and to find one Sealed or willing to be Skill Stored, it could be said that even in the entire mainland, one could count on the fingers of a hand.
