The Sole-Ki Pearl of Primalwater was a naturally occurring spirit-treasure that was one of the most superb resources for nourishing the soul.
There were some Immortal cultivators who, believing their Zifu's to be damaged, would steal the bodies of others. This sort of possession, however… had a major problem. It was that the affinity between the body and the soul would be very weak. Generally speaking, most bodies were not of very high quality. Some Immortal cultivators, upon finding a good body, would seize it. Once their affinity with it reached a certain level, they would be extremely satisfied.
However, the likes of the Darkvalley Pearl, the Sole-Ki Pearl of Primalwater, and other such naturally occurring spirit-treasures were truly perfect vessels. Because they had never been inhabited by a soul, once a soul did enter them, they would merge together perfectly. In terms of quality, as naturally occurring spirit-treasures, they were of course of superb quality.
