The Chaotic Origin Energy was the energy present in a higher dimensional beyond the Origin World. Deep in that higher dimension, the Chaotic Origin Energy was much denser. Even Cosmos Gods did not dare to enter since they would die the moment they touched the Chaotic Origin Energy!
Currently, only those who grasped the 'Great Destruction Realm Teleportation Technique' had the capabilities to penetrate through it. And even as they tunneled through it, they did not dare to touch the Chaotic Origin Energy from a higher dimension as it was too concentrated and intense. Even if the cultivator maintained the pinnacle of void-ification, he would still be corroded to death.
And this mysterious energy was rarefied closer to the Origin World.
