Thousands of years ago, the first alchemist in Zhongzhou, Danchen, was killed by his apprentice, and a generation of Dan Saints fell. A thousand years later, Danchen was reborn, only to find that the apprentice who had killed him had been transformed into a saint nine times, unifying the Dan realm, and was known as the "Heavenly Dan Sage". The Huntian Dansheng dominates the world with thunderous means and is powerful in all directions; Commanding the storm, immortal and immortal. Danchen stood outside the ancestral hall of all saints, looking at the statue of the Huntian Dansheng, and the flames of hatred burned in his heart, "Thirty years in Hedong, thirty years in Hexi, when I rebuild for thirteen years, I dare to call Dansheng to go to Huangquan."
