Chen Yu had always harbored doubts about this matter. Based on what he currently knew, ancient immortals had indeed once existed on this planet; after all, he had already discovered their existence within the Tombs of the Immortals. However, the current cultivation methods and realms fell completely short of the era when the ancient immortals lived.
Moreover, where had all the ancient immortals from the past gone? Could they all be slumbering inside the Tombs of the Immortals?
And what was the deal with those ancient immortals from the Upper Realm?
What on earth were their intentions toward this realm?
Hearing Chen Yu's question, Ao Yin thought for a moment and said, "Master, ancient immortals did indeed exist on this planet in the past, but they all went to the Upper Realm. Three thousand years ago, the Dao flourished on this planet with a hundred schools of thought contending. Back then, not only did we have Eastern immortals, but Western deities also coexisted in this realm."
