"Xuantian Supreme Scripture," said to be an incomplete Emperor Scripture, is deemed as such because theoretically, it can grow into a cultivation technique comparable to an Emperor Level technique.
However, this requires the cultivator to tirelessly collect other techniques, integrating them by absorbing their strengths and compensating for their weaknesses, incorporating various merits, and ultimately achieving greatness by merging them into one and becoming an Emperor Level technique.
Before the Primordial Spirit Realm, those are only minor realms; the techniques cultivated by Tang Yi are sufficient to elevate the "Xuantian Supreme Scripture."
But as the realm progresses, the "Xuantian Supreme Scripture" must also be continuously upgraded. Upon reaching the Primordial Spirit Realm, Tang Yi would likely need to acquire dozens, if not hundreds, of Primordial Spirit Realm techniques to level up the "Xuantian Supreme Scripture" to a Primordial Spirit Level.
