Immediate and future potential

In the Foundation Building Realm the practitioner condensed small crystals inside the vortex of Spiritual Qi that was formed in the Revolving Qi Realm and was by the 9th level rotating at incredibly high speed and with high density.

These crystals were not strictly speaking Spiritual Qi in its pure form, as they were not spent when the cultivator emptied their reserves of Spiritual Qi, but a condensation of the practitioner's cultivation base.

In total a cultivator would form nine crystals by the 9th level of Foundation Building Realm, with Wu Long currently having none as he was in the gate of the realm.

'...so it is finally time for a grind huh... Foundation Building Realm all over again'
