The present Five Villages Temple is already considered the Earth Immortal Dao, following the Earth Immortal Path.
And the Qi Cultivation Technique of the Five Villages Temple is inherited from Immortals, who come from the Thirty-Three Heavens of the Spiritual World...
Zhang Chen seemed to grasp a faint thread of this. Everything points to the Thirty-Three Heavens, where even the peacock refers to it as the Immortal Realm. It must be the origin of Qi Cultivators.
Could it be that after slaying all divine spirits on Earth, someone founded the Qi Cultivation Technique and entered the Thirty-Three Heavens to cultivate?
Zhang Chen didn't quite believe that the Martial Dao he taught could have such heaven-defying power. If someone truly comprehended Qi Cultivation Technique and mastered the ways of it, gathering the mighty powers of a myriad of divine spirits, then such abilities would be understandable.
