The inheritance is incomplete, a significant problem.
This was one of the reasons why Xu Yang strove for supremacy over the realm.
The current Taoism holds tremendous potential and numerous benefits.
He did not wish to abandon it, yet the inheritance was flawed.
The only solution was to gather a collective force to usher in a golden age of Taoism. Like deriving the Martial Arts Scripture, they relied on the wisdom of all beings to deduce the divine skills of Taoism.
Therefore, he intended to unify the realm.
As for ascension... he was not considering it for the time being.
Since he was an "unregistered" being and was unaware of the conditions in the Upper Realm, should there exist supreme beings like the Ancestral Daoist and Ancestral Buddha above, his ascension would be like stepping into a trap.
Such powerful beings could, with a casual glance, likely see through his origins as an "extraterritorial Heavenly Demon.
