The place where Du Yuying went was the tomb of the Celestials; it made Li Xuan think of the place where Zi Yun went. Could it be the tomb of the Celestials, too?
So far, the Inner Realm does not have any Celestial Martial Artists.
It seemed that the conditions to become a Celestial Martial Artist are not met, but the specific reason is unknown.
"If it really is the tomb of the Celestials, Xu Yan should be able to find out why there are no Celestial Martial Artists in the Inner Realm."
Li Xuan thought in his heart.
After Xu Yan left, Xie Lingfeng and Hu Shan also took their leave to return to the Cliff of Sword Sovereign for cultivation, guided by Li Xuan's instructions on the Sword Dao and brought back some elixirs needed for transforming their cultivation techniques and condensing the Bridge of Heaven and Earth.
