But the difference is that for mortals, it's only the first layer, and when they have exhausted these ten thousand layers of the Realm, what they achieve is merely a Realm that barely grants Longevity. Although it has the essence of Longevity, it offers no more.
On the other hand, for a Spiritual Realm Level Nine Strongest cultivator, they are already standing at the nine thousand nine hundredth layer, needing only one hundred layers of power to reach the Eternal Realm. And with the ten thousand layers of power bestowed by Heaven and Earth, the remaining nine thousand nine hundred layers of power will not vanish; they will continue to be added to them, allowing them to further enhance their cultivation and walk further on the path of Longevity, attaining even higher Realms.
The Heavenly Dao is impartial, treating every creature equally, never failing to acknowledge all of your efforts. The cultivation of now will not be wasted in the Future.
