Prehistoric Xuan Ming Lu

He traveled through time and came to the ancient world, but Xuan Ming always felt that something was wrong with this ancient world. After finishing his training, Xuan Ming exhaled a breath, and then watched the breath evolve in the void, creating a multiverse... So I'm not just in the qi training period? Who is so good at Qi training? ? How about saying which ancient practice followed the path of "qi training" and "golden elixir"? Is this a prehistoric myth or a fairy cultivation? ?
