Capítulo 308: 184, borrowing this from all Daoist friends for a moment_2

When the two confirmations merge on the path, after undergoing the questioning of the heavens and earth, they are actually already bound to that piece of heaven and earth. If the mortal breath is considered a restraint imposed by the Primordial Heavenly Realm on mortal beings, then these two confirmations act as a restraint on those who have just begun to attain immortality.

Logically speaking, after merging the two confirmations on the path, trying to return to the mortal realm from the Land of the Four Pillars would be extremely difficult, because one would first be repulsed by the will of this heaven and earth. Similarly, attempting to reach the Primordial Heavenly Realm would also become exceedingly challenging.

Mentor slaying was her lifelong dream.
