While the war was in full swing, Wu Qi and Princess Zhang Le had secretly left Dong Hai to the reverse side of Pangu Continent.
In the primal world located between the topside and reverse side of Pangu Continent, Wu Qi constructed a colossal Fiend Slaying Sword Formation using nine Blood-draining Celestial Fiends as the eyes of the formation and 3,600 Kunwu Swords he had condensed with the Primal Purple Energy. 108,000 fist-sized purple globes of light floated in the formation, the stars condensed from the Great Daos he had obtained from the Kaleidoscopic Star Core.
