Primordial Era: I am the chief disciple of the Three Pure Ones, the gatekeeper of the Great Dao.

Having traversed the primordial world, Cang Xuan became the chief disciple of the Three Pure Ones and was bound to the Great Dao Gatekeeper System.
Since the Three Pure Ones founded their sect and attained sainthood, Kunlun Mountain has become a sacred place in the hearts of all living beings in the primordial world.
However, those who wanted to become disciples were blocked outside the mountain gate by Cang Xuan.
"Those burdened with karmic debts cannot enter the Xuanmen (Taoist sect)!"
He saw through the wicked intentions and murderous sins of those who were bound to him, and kept them out of the door.
Those who sought the Dao but were ignorant of the ways of Heaven and deeply entangled in the great calamity were politely refused by him.
Therefore, all the disciples of Xuanmen were of profound talent and upright character, and there was never any discord between Chanjiao and Jiejiao, so the Three Pure Ones never separated.
Ten thousand years later, the Lich War ended, and the God Conferring War began.
Hongjun Daozu personally manifested on Kunlun Mountain, intending to summon the Three Pure Ones to Zixiao Palace for a meeting, with the intention of having them sign the Investiture of the Gods.
"By order of the Three Pure Ones, I guard the Xuanmen!"
Cang Xuan slashed down with his sword, his aura as powerful as a rainbow: "Ancestor Hongjun, why do you rebel?"
Hongjun was stunned: "Why can't I defeat him?"
