The Black Bull also recalled its experiences.
It didn't cultivate the Law; it only cultivated the Physical Body, walking a unique path.
It didn't need to harmonize with the Great Dao, only to refine its body to the extreme, reaching the level of proving the Dao through strength.
Although that path was different, its danger was not inferior to the ordinary Harmonization.
During body refining, it was often covered in wounds, bloodied, and several times nearly didn't make it through.
The Old Cyan Dragon was a bit better, not as bumpy as them, but its breakthrough was likewise not easy back then.
Moreover, it followed Gui Xu Taoist for many years, witnessing countless cultivators fail to achieve Harmonization.
Those failures, some would explode and perish on the spot, some would have Divine Thought collapse and turn into idiots, some would be countered by the Great Dao and become ashes.
Each one was a living lesson.
