No matter how powerful the Heavenly Dao is, it will be encapsulated in a stable Ancestral Artifact because it needs to be controlled and used to adjust the world's principles.
Many Heavenly Daos are sealed within Ancestral Artifacts.
But it is clear that the first Heavenly Dao Law is very special because it created all the Heavenly Dao Laws and the Ancestral Artifact capable of containing them was also its creation.
This means there is no Ancestral Artifact that can constrain it.
It is difficult to be stored in any Ancestral Artifact and hard to be controlled by any cultivator.
Therefore, trying to control it by Merging Dao is impossible.
But no matter how strong it is, it was created by a terrifying and powerful Creator!
This means that the Creator left a backdoor.
Houtu studied the first Primordial Heavenly Dao for a thousand years, understanding it from all aspects. Despite never finding a way to subdue it, its characteristics were thoroughly investigated.
