Ye Fan's greatest gain was the Spirit Stone, which enhanced his clairvoyance ability, no, it should be called Divine Sense. After absorbing the Spirit Stone, Ye Fan not only improved his abilities but also acquired a wealth of information. The Spirit Stone contained not only a vast array of battle techniques for manipulating the guards but also recorded the functions of the Spirit Stone itself; it could stimulate one's Divine Sense and also strengthen it.
Ye Fan also learned that what he called the Clairvoyant Eye was in fact Divine Sense, a power even higher than telekinesis. Ye Fan had inadvertently activated his Heavenly Eye before, gaining Divine Sense, and the Clairvoyant Eye was just a part of the functionality of Divine Sense.
