Ladies Among the Immortals, Gods, Demons, and Sages, I Really Have No Powerful Backing

[Villain + second-generation emperor + supreme imperial clan + eternal emperor-slayer father + in short, an overwhelmingly terrifying background] Gu Yuan was dumped in the lower realm by his heartless father to spread their family line. By chance, he bound himself to the "Female Lead Plundering Villain System," which lets him target all kinds of peerless female leads among immortals, gods, demons, and saintesses. Queen Medusa wanted to transform into a dragon. Seeing the nine-clawed purple dragon robe on Gu Yuan, she fell into deep thought. Three claws make a jiao, four make a dragon, five make a sovereign. What on earth is a nine-clawed one?! Only after her bloodline transformed into a dragon did she learn that "Nine-Army Purple Radiance God-Slaying Forbidden Domain Dragon" and "Purple Mystic Nine Radiance Supreme Grand Sovereign Dragon" were both her names. A haughty, scheming little demoness angered the three thousand great sects of the righteous path. Countless elders of the demonic sect died in battle. Despairing, she offered her body to Gu Yuan of her own accord and bore him children. Then the world's origin and the laws of the Great Dao changed. The three thousand Daoist sects became demonic sects surging with demonic energy, while her sect resonated with the sounds of the Great Dao, and boundless golden merit light descended from the heavens. Only later did she learn that what Gu Yuan's heartless father said was known as the Cosmic Dao Principles. His father had an idea that, across the boundless star domains, was called the Supreme Will! "Those who bully my daughter-in-law shall sink for all eternity in the hell of endless reincarnation!"
