My Emperor Venerable Has Turned Dark Again

She was the strongest supernatural ability user at a base in the apocalyptic world of the late twenty-second century. In a great battle, she and the Zombie Emperor died together. After transmigrating, she found herself in the body of Li Ji Ge, the notorious good-for-nothing young lady of Jinzhou City. No mystical power, no ability to cultivate, and a figure as fat as a pig? Sorry, but her seal is broken, and she can wield every elemental ability! She excels at both medicine and poison, and getting her beauty back is no problem! A scumbag's schemes, a lethal poison in her veins, and her family on the verge of ruin? She'll repay every wrong a hundredfold. This lady will have you all behaving yourselves in no time! He is the revered and noble Sovereign, with unfathomable strength. His moods are unpredictable and he kills without mercy, inspiring fear in everyone.
