Endless, with no limitations.
For life beings, Bloodline Spirit Rhinoceros is the source of life. Yet isn't Bloodline Spirit Rhinoceros also a limitation?
Bloodline Spirit Rhinoceros grants life beings "birth," but it also brings "aging" and "death." Lifespan is the greatest limitation a life being must face.
Apart from the Sea God Type, those Innate Saints born with longevity, the cultivation of the vast majority of life beings is a process of freeing themselves from this bloodline constraint. And the path for Shenzhou creatures is to build a new physiological system with Spiritual Energy, to shed the physical body, and thus, break free from the constraints of bloodline.
But are the constraints of bloodline on life beings limited only to their lifespan?
