My Divine Core Shattered, and I Was Reborn as a Useless Young Lady of a Marquis’s House

Also known as After Being Reborn as a Worthless Heiress, I Was Relentlessly Pursued by a Two-Faced Big Shot [Two-faced god and demon big shot: a beautiful, kindhearted, innocent God Venerable + a flamboyant, arrogant, lawless Demon Lord; sharp-tongued, scheming, unlucky worthless girl; sweet romance, exclusive devotion, protective partner, taming her husband, devoted to each other] “She” was a divine ruler in the God Realm, a heaven-blessed prodigy with extraordinary talent. “She” was the legitimate daughter of a marquis, yet lived worse than a dog. With her spiritual meridians completely crippled, she was the biggest joke in Jincheng. “Her” divine core shattered, and she fell from the heavens. “She” endured endless humiliation and abuse, then died, only to return reborn and awaken a divine flame rarely seen in the world. From then on, the worthless girl became a genius, advancing by leaps and bounds. She beat down fake sweethearts, cut down scumbags, and kicked anyone who bullied the weak. Alchemy and weapon crafting came easily to her. Her bloodline awakened, and all beasts submitted. Fearless, she wielded demonic bone and provoked the Demon Lord of the Demon Realm, hated by both gods and mortals. He chased, she ran, but she couldn't escape. A certain God Venerable: “Song Luosheng, I left something at your place.” Song Luosheng: “?? What thing?” “My heart!” A certain Demon Lord: “You mere crawling insect dare dream of laying a hand on my body? Song Luosheng, you have successfully angered me.” Song Luosheng trembled. Wait, weren't we just kissing? Why are you suddenly transforming??
