Xia Ji was very clear.
None of his skills had reached the tenth level.
The stacking of two Skill Orbs of the same quality would only increase the quality.
The reason why he was able to reach the 11th realm was because his essence, qi, and spirit had reached the peak. Moreover, his state of mind was complete. With a trace of opportunity, he had touched the limit and thus advanced.
However, after upgrading, he could no longer find a way to continue advancing.
Every realm had a gap. Entering the realm was just the beginning, and to reach the next realm, there was still a long way to go. For example, there were four realms in both the Postnatal and Connate realms, but why was it that the Ninth Supreme and the Tenth Spell only had one realm?
The reason was simple. Few people had reached it, so no one would differentiate between them. But in fact, there were many sub-realms in both the Ninth Supreme and Tenth Dharma Plane.
It was the same for the eleventh avatar.
