Qingcheng doesn't have other successors, after all, Lingxu's teachings are too mixed and complicated, only someone like Sect Leader Tie Dan at Level 1 can understand his philosophy. The newly initiated disciples can hardly grasp his True Inheritor status. Furthermore, he clearly isn't interested in developing the sect. He casually writes a couple of Books, hides some treasures, and that's it.
Moreover, the Eight Immortals Sword technique is clearly outlined in the Sword Scripture annotations. It was created by him after observing the Blood Talisman Divine Sword, referencing the Divine Lord's cultivation concepts of Divinity Transformation, Blood Transformation, and Sword Transformation, then fusion with his lifetime learning, and evolving the terrains of Qingcheng Mountain and Jing Mountain. It is a unique, unprecedented ultimate move.
