Originally, with her Golden Core Stage cultivation, having been the lover of the current Baiyue True Person, it was a natural step for her to become his Dao companion.
But the problem was, the current Baiyue True Person already had a Dao companion, who was a descendant of a Nascent Soul Stage True Person who had already fallen.
Even though his Dao companion had perished during the Core Formation process, this connection made it difficult for Su Yunniang to formalize her position.
After all, being the Sect Leader True Person, he must set an example and consider the bigger picture of the sect.
If the current Baiyue True Person were to recognize Su Yunniang as his Dao companion now, he would certainly offend the family of his original Dao companion.
Although that family, due to the fall of the Nascent Soul Stage True Person, is now only led by a Golden Elixir Early Phase cultivator, the favor left by the ancestors still carries significant influence within the Moon Wheel Sect.
