From Emperor Jing of Liang's memory, he learned that in the Upper Realm, very few immortals can truly live to the end of their lifespan.
Because in the Upper Realm, immortals are composed of the most powerful cultivators from each era of the Three Thousand Small Worlds over billions of years.
The Upper Realm is not much larger than the Three Thousand Small Worlds below.
Thus, the struggle among immortals in the Upper Realm is extremely fierce.
The frequency of conflicts in the Upper Realm is incomparable to any single Small World below.
Although some immortals have considered that if the immortals of the Upper Realm live in harmony, they could collectively seek longevity.
However, resources such as celestial medicine and cave mansions in the Upper Realm are limited.
Even though they have become immortals, human nature remains unchanged.
