Gu Zhan immediately understood what those beads were; they were mediums for inheriting secret manuals in the Cultivation Realm, similar to the Inheritance Jade Slip used in Martial Arts. However, the Inheritance Pill Beads in the Cultivation Realm were relatively more advanced, containing restrictions that those with low cultivation couldn't possibly know about. If not careful, triggering the restrictions could lead to the Inheritance Pill Bead self-destructing.
This explains why, after ten thousand years, no one in the Human World has found the true inheritance of the Cultivation Realm, only barely uncovering a scattered small inheritance, with great difficulty. Even if there are inheritances scattered across the Human World, they remain untouched because nobody knows how to open them, and over time without spiritual energy replenishment, they gradually vanish.
