Perfected Realm, a Traitor's Regret!

Elder Cao threw back his head and let out a long howl, his black robe snapping in the wind!

He was at the Sixth-Level Great Ability Realm, a full five levels above Lin Feng. Lin Feng had only just entered the Mighty Realm and had not even stabilized his cultivation!
