Well first of all u will need a Celestial Schism and 200 Mirages , 2nd u will need to do ALL CULTIVATION QUESTS , in order to use the Celestial schism & the mirages at Conversion manager in 1k city . After u did all culti quests , get the celestial schism and the mirages go to Conversion manager in 1k near the Blue Portal , and u'll see there. I did same for my Seeker to change from Demon to Sage. Good luck.
