Though countless people were cultivating immortality, not everyone could live to be a thousand years old and possess an amazing talent. The continent they lived on was known as the Upper Realm, but this was only because the rich spirit energy here made it more suitable for immortal cultivators to live.
This did not, however, imply that every cultivator here possessed incredible strength, nor that Celestial Level Strong Exponents could be found everywhere. After all, only the Venerables of the great sects could possibly have the kind of strength possessed by Celestial Level Strong Exponents in their realm here.
Which of the Venerables wasn't an old monster who'd been cultivating for hundreds of years? Which of them was not their clan's old predecessor? Even if many clans gave their all, they would not be able to produce a Celestial Level Strong Exponent, demonstrating how solid those sects' positions were.
