Whether it is the stimulation of the environment, the erosion of substances, the damage from energy, or the constraints of conceptual rules—once a threat endangers its life, it will quickly develop immunity; once harm is inflicted on its body, it will rapidly evolve. This is Absolute Adaptation. In this hellish chaotic world, monsters want to devour it when they see it, and immortals want to refine it into elixirs when they encounter it. It is the finest heavenly treasure in the world, and also the most perfect cauldron (for alchemy) in the world. Yet, all things that fail to kill it—such as Daoist techniques, magical artifacts, talismans, divine weapons, true fire, heavenly tribulation thunder, death rays, killing formations... will only make it stronger.
