My name is Gu Niazhang, and it is my destiny to become a humanoid elixir. It's a pity that God won't accept me. Good people don't live long, and disasters last for thousands of years. I survived the catastrophe and gained the secret skills inherited from thirteen side sects to conquer the Xuanmen world. From then on, all the forbidden arts of the Yin Sect, the methods of controlling ghosts and refining corpses, and the means of using magic to connect Yin and Yang are all under my control.
Heavy rains burst open ancient tombs, and corpses appeared in the world after trampling on coffins. The terrifying folk taboos spread in mountain villages were fulfilled one by one. Countless evil cultivators and fake immortals used yin magic to harm mortals, and used the bones of dead souls to refine evil spirits.
The righteous way is powerless against the most evil corpses, ghosts, and evil spirits. Only these side-door magics that everyone despises in my hands can suppress the evil things that cause harm to the yin and yang.
Everyone in the world is afraid of me because of my Yin Dharma, and scolds me for practicing heretical ways. But I walk in Yin and Yang, only killing evil and protecting good.
There is no good or evil in witchcraft. Only the mind of the person who performs the magic can distinguish between good and evil.
