If the Heavenly Dao Path is the foundation upon which Qi Refinement cultivators are called ancestors...
Then turning the false into the real is the foundation upon which soul cultivators call themselves ancestors.
In the universe's three thousand paths, Qi Refinement is revered, with legalist cultivation, soul cultivation, body cultivation, sword cultivation, and others as the orthodox practices.
Though all are considered orthodox, the ways differ.
For example, legalist cultivators understand rules through spellcasting, and from rules, they comprehend the source.
Body cultivators are oppressed by the will of the Heavenly Dao, facing formidable obstacles at every step.
As for soul cultivators, while their overall advancement speed rivals all other paths, they are hindered by several unimaginably difficult bottlenecks.
The Dao Ancestor is precisely one of these major bottlenecks in soul cultivation.
