This universe was very strange, almost devoid of Immortal Spiritual Power.
Even, it was inferior to the Lower Realm of the Sixfold Heavens.
In such a place, maintaining one's Cultivation Level was already an achievement, let alone improving strength.
If someone assumed that, in this universe, the Great Sun suddenly had a stroke of luck, found a treasure, and increased his strength?
If that was the guess, then stop kidding around.
That would be less likely than speculating that the Great Sun had an adventure in the Sixfold Heavens, found a treasure, suddenly gained enlightenment, and reincarnated as a Daoist Ancestor.
"However, you must be careful, as vast as the universe is, there is still a one in a billion chance of encountering the Great Sun," said Qi Yuan. "If you do, run straight to the Sixfold Heavens."
Despite the one in a billion probability, caution was still necessary.
