This piece of Spirit Jade is named Trace Origin Immortal Spirit Jade, one of the Immortal Treasures brought down from the Immortal Realm by the Celestial Realm Descent True Immortal.
It can leave a Trace Origin Mark in any particular world, allowing surveillance of this world through the Trace Origin Immortal Spirit Jade, even if it is obstructed by many layers of worlds.
This Immortal Treasure was prepared for observing the movements in other Cultivation Worlds and to prevent Bizarre Demons that were sealed from breaking out.
In coordination with the Nine Heavens Trace Origin Immortal Spirit Mirror Array, it can mark up to eighty-one Trace Origins, allowing surveillance over more than eighty Cultivation Worlds.
Similar Immortal Treasures exist in the Spirit Realm, forming together a complete monitoring system.
They serve to timely check for deficiencies and prevent the issue of Bizarre Demons from growing to an irreparable extent.
