Tongtian Sect Master, upon emerging from seclusion, would certainly achieve the state of Primordial Daluo Golden Immortal, as would Taiching.
At that time, it would be the moment to confrontation openly with Heavenly Dao and Daoist Ancestor of Purple Cloud Palace.
"I understand!"
Xuanqing immediately nodded in agreement.
Establishing the Taoist school and formally unifying the three teachings, folding in the human, elucidation, and severance teachings, indeed, there was no one more suitable than him!
The Three Pure Ones represented their respective teachings and it wouldn't be appropriate for them to personally intervene. If all three intervened, any school that was established would only be considered a coalition.
As for the other disciples, firstly, their abilities did not match Xuanqing's, and secondly, they had not learned nearly all the methods of the Three Pure Ones like Xuanqing had.
