The two disciples, Xiaoge and Jun did not know the events that were going to happen soon. The two of them were deep in mediation and were focusing on improving their cultivation as much as they could.
They had rejected the inheritance of the Sky Bright Daoist and were instead going to go ahead and take the trials of the Taiji Celestial. They actually didn't even know that the place they were going to was the tomb of the Taiji Celestial.
Neither did they know the name Taiji Celestial either. They simply knew that they were going to go to the tomb of a mighty figure and that the said figure was the one who had given Wang Xiong, their senior brother and Chief disciple of the Frozen Cloud sect, the power that he had now.
