Even though Tianlong Yun had thought this to be the case, it was only now that he was slowly proving this theory of his.
It wasn't that normal cultivators didn't collect Soul Power, it was only that they were doing that unintentionally during their meditations, and what they collected was extremely crude and unrefined.
The geniuses or those who had great souls would certainly be able and capable of collecting more Soul Power, and their condition would certainly be better than the rest.
But even in that case, it was only done so by pure instinct. They had no idea that Soul Power and Soul Strength were one of the main steps to reaching the next Realm or having their breakthrough.
If it weren't for the legacy of that Ancient Cultivator, and his trip to the Soul Realm, Tianlong Yun would also have been completely ignorant of the fact.
Every disaster hides an opportunity, and every opportunity is accompanied by a disaster.
