The Villainess Always Breaks Character

(Not a wish-fulfillment story + slow-paced + don't read if that's not your thing) If you're going to transmigrate into a book, so be it! But why do you have to be a minor villainous boss? And as if that weren't bad enough, you're a sickly beauty with no spiritual root, unable to cultivate. You've maxed out every handicap. Luckily, she has a powerful golden finger and a loyal little villain as her husband. The only problem is, she's charging full speed ahead on the road to breaking character. A sickly beauty? A sickly beauty who can kill an eight-foot-tall man with one punch?
