But actually, they did not have any choice. Even the Taoist Jun Tian and the other eight experts of Origin could not practice the Air of Chaos unless they possessed Magic Weapons just like the Cauldron of Heaven and Earth, which could turn the Air of Chaos into the Primordial Spiritual Air. Otherwise, they could hardly survive in the Chaos leaving the World of Five Elements.
Every Cultivator needed Spiritual Air for cultivation. The Air of Chaos was a special Spiritual Air, and only the Rakshasa could use it. Once the Taoist Jun Tian and other people left the World of Five Elements, they would lose alimentative Spiritual Air. They would die if they could not find a place to supplement supernatural power before running out of it.
