"There is always a higher mountain to climb"- a famous saying among the myriad of worlds, regardless of status, power, race, or gender. It doesn't stop there. Although the wording might change, the meaning is always the same.
It means there is always something higher to aim for, whether that be power, status, strength, knowledge, or whatever it is you want to excel at. You can always be better and should always strive for something better.
Cultivation, at its core, is essentially the manifestation of this saying. For a normal village child, someone at the Qi Condensation might be the top of the mountain for them. While for a Qi Condensation Realm cultivator, it's the Foundation Realm or the Core Formation Realm.
For a Divine Sea Realm expert, the top of the mountain is the Ascension Realm. That's not only the case for Divine Sea Realm experts either. The Ascension Realm is the peak for all in the Mortal Realm!
