As for the Purifying Pill, it follows the Path of Heart Refining, a Mind Pill that is unique in the entire Three Realms, capable of honing the spiritual will of Immortals and Buddhas.
This pill was left behind by the Tao Ancestor, refined with Primordial Qi fallen from the Chaos Heaven by the Pure Heaven, extracting the Fierce Qi within, and transformed into a pill using Supreme Tao Techniques.
Although this pill is named Purifying Pill, it is extremely perilous. After consuming the pill, the mind will be tempered by the chaotic and violent forces, and any slight negligence may lead to losing one's mind, resulting in the scattering of the soul, and the annihilation of the self.
Even Celestial Venerates are reluctant to come into contact with it; only those who wish to advance further on the path to becoming a Great Emperor might seek to obtain the Purifying Pill by any means necessary.
