Heaven-Defying Madwoman: I Use the System to Crush the World

She was a concubine-born daughter of the Feng family of Cang, blessed with breathtaking beauty. Yet her elder sister stole her betrothal, her fiancé falsely accused her of infidelity, and her younger sister disfigured her, broke all four of her limbs, and threw her off a cliff! Then the modern-day mercenary "Fox" transmigrates into her body, armed with a System and looking down on the world. As for the scumbag men and vile women? Hah. They won't even get the chance to offend her eyes before she crushes them all. And as for the handsome man who fell from the sky... Before she can do a thing, he has already collapsed to the ground, all weak and pliant. "My lady, I'm still recovering. I'm afraid you'll have to bear with me."
