This was not a stone, but the core of the Wisdom Clan, the Wisdom Core.
All members of the Wisdom Clan who had awakened their innate intelligence possessed a Wisdom Core within their bodies, which was the foundation of their existence, storing the consciousness of their true selves.
To upgrade from an Intelligent Spirit to an Intelligent Teacher, one must first upgrade the Wisdom Core, strengthen this consciousness, and then change to a new Wisdom Clan body to complete the upgrade.
For the Immortal Realm, this Wisdom Core was also a valuable object, for it contained Origin Qi. The higher the level of the Wisdom Clan member, the more Origin Qi their Wisdom Core contained.
Through special refining techniques, the Origin Qi could be extracted, whether it was integrated into an Immortal Artifact or absorbed directly, it was of great benefit.
For Han Yi, however, he didn't need to refine the device to extract the Origin Qi; he could absorb it directly.
