Refining Void, Harmonization, Tribulation Crossing, these are the last three realms of the Mortal Realm.
A Void Refining Cultivator, though inferior to a Harmonization Cultivator or a Tribulation Crossing Cultivator, still possesses a certain ability for self-preservation.
High-level cultivators deduce the changes in celestial secrets, often relying on the Heavenly Dao Laws, observing the traces left by all beings, calculating the unknown from the known, and gaining some heavenly insights and knowledge of all beings.
However, there are still some blind spots.
That is the Grotto Heavens created by cultivators, independent of the Purple Mansion World, with a weak causal link to the Heavenly Dao. If one hides within the Grotto Heaven, even Tribulation Crossing Cultivators may not be able to calculate its position, and in times of crisis, it can be used to preserve the flame of a clan or sect.
In the vast history, how many great sects have been born, how many great clans.
