For the people of the Mountain and Sea Realm, who are generally of the longevity breed, time doesn't hold much value.
However, perhaps it is precisely because of the unique perspective of those with longevity that the Mountain and Sea Realm has not seen any striking new changes for a long time.
The civilization seems stagnant, culture has no new ideas...
In the normal course of civilization development, a few hundred years is already a long iteration of time.
Over thousands of years, waves of ideological tides would emerge, leading the entire civilization to undergo transformation.
Call it the Renaissance or the Enlightenment.
Civilization is constantly updated in iterations through waves of ideological tides, ascending in a spiral of contradictions.
This is the cyclical law of history, as well as the ladder of civilizational progress.
Yet, when this cyclical law and ladder reached the Mountain and Sea Civilization, it manifested an eerie phenomenon of "stagnation."
