Chen Guan hadn't seen this thing before and didn't know its purpose.
He gathered Body Protection Divine Skill to protect his body and stretched out his hand to absorb the crystal core.
The crystal core was only the size of a pigeon egg, with countless facets on it. Even the best gem polishers couldn't craft facets so perfectly; each facet was astonishingly uniform and perfect, with angles so precise.
Through those facets, one could see what seemed like blue ripples swaying inside, but it was perceivable that it wasn't true wave energy but a type of primordial energy similar to the Biluochi crystal, yet purer and higher in quality.
When Chen Guan's spiritual sense penetrated the crystal core, information simultaneously surfaced.
Realm: 1.
"Realm 1? What does it mean? Can using this thing directly elevate one realm? How should one define this realm? What kind of realm is this?" Chen Guan speculated to himself.
