After Sacrificing My Left Eye, the Mad Demon Venerable Begs Me Not to Die

[Strong female lead + reborn for revenge + cold and self-serving + ruthless madwoman + regretful ex pursues her + decisive and merciless + no forgiveness] In her previous life, she was a worthless mortal, despised by everyone. Her husband and senior sister joined forces to sacrifice her, refining her into a sixth-rank Myriad-Erosion Butterfly spirit seed. Only when she died in agony did she learn the truth: her family had always treated her like worthless garbage. Reborn with vengeance in her heart, she claimed a demonic sword and made a life-and-death pact with the lingering soul of the Demon Lord. She forced open her spiritual aperture at the cost of forty years of her life, her black hair turning white. Then she sacrificed her left eye to forge a ninth-rank divine eye. From then on, her heart was as cold as iron, and she became ruthlessly self-serving, focused only on attaining immortality. If it’s useful, she takes it. If it stands in her way, she kills it. She never explains herself. After feigning a divorce and faking her death to escape, she returned to the clan that had abandoned her and turned it upside down with bloodshed! Her ex-husband thinks she died young of heartbreak over him. He goes mad searching the world for her, and his pursuit becomes a living hell. The Demon Lord initially sees her as a weapon, and they use each other. But after spending day and night together, he eventually bows his head. “You alone are worthy to stand at my side and rule this world.” He doesn’t know that her very existence is the karmic consequence he set in motion a thousand years ago. * All living things are born with spirit seeds. People open their spiritual apertures and wield spirits through qi, becoming spirit tamers. Spirit seeds and spirit tamers are ranked from one to nine. [Content warning: The female lead is a demonic cultivator, not a good person. If you get in the way of her interests, she’ll kill you. She won’t hesitate to take revenge on her family, wipe out entire clans, or seize resources. There is a regretful-ex pursuit, but the female lead watches coldly and never looks back.
