The Poisoned Legitimate Daughter: The Heaven-Defying Beast Consort Won't Enter the Household

Nie Shuiyao was the king of mercenaries in the 21st century, but after transmigrating, she became a good-for-nothing! Her fiancé broke off their engagement? Her two-faced, scheming sisters framed her? Her scumbag father hated her to the bone? A good-for-nothing wasn't allowed to have thoughts or opinions of her own? Then this good-for-nothing would beat everyone into submission and rise above all the beasts! But... can someone tell her when her good-for-nothing husband became the Dark Lord???
