Yin Flourishing, Yang Waning? What Does That Have to Do with Me, a Mere Furnace Vessel?

(Female dominance and male decline + reverse reasoning + not a wish-fulfillment story + alternate universe + slow pace) Reborn into this cultivation world where yin prevails over yang, An Sheng was cautious and timid from a young age, only seeking a peaceful cultivation path and to live a little longer. Unfortunately, the kind older sister in the clan is a perverted person with a bone fetish, and she thinks all day long about turning him into a bone furnace. In order to avoid being turned into a magical artifact for others to play with, the boy had no choice but to take the risk and cultivate the supernatural power [Myriad Transformations of Other Self and Past Lives]. From then on, the heavens and earth were vast and the universe boundless. He was a young witch clan member living a precarious life, and also a fox spirit aiding and abetting evil; he was both a righteous hero who bravely faced death and a demonic leader who wreaked havoc on the world... But the boy was unaware that every gift from fate comes at a price, and that an incredibly terrifying being was already secretly watching him... The Twelve Ancestors of the Witch Gods, the Boundless Purgatory Path. Cultivate the Soul-Devouring Body, chant the Curse of Resentment and Death, refine the Blood of Sorrow, bury the Bones of Life and Death, ignite the Heart Fire with the Seven Emotions, let the Moon Illuminate the Vast Expanse, Ask the Ancient Sect of Heaven, the Fiend of Another Realm, the Great Black Heaven, the Lotus Mother, the Hundred-Armed Demon... "Well, let's be reasonable. It's impossible for me to be your furnace, your Daoist partner, your tool, your elder, your pet, your best friend, your worst enemy, and your life mentor all at the same time." The boy fought and retreated, then requested a reconciliation. "Why not?" The fairies smiled radiantly and spoke in unison.
