A Max-Level Expert Transmigrates, So Why Are You Picking a Fight with Her?

Premise: Dark in tone, not a wish-fulfillment story

The heroine is awful and doesn't know it. She torments the male lead's entire family while believing she's doing it all for his own good. There's no groveling to win him back; by the time she comes to her senses, the male lead is already dead.

In her previous life, the heroine was a great fiend in the cultivation world. She killed without blinking, had no moral boundaries, and was hunted by the whole world. Before she died, she escaped by shedding her shell and reincarnating in another world. She hasn't changed her ways, and her past self continues to influence the way she acts in this life.

After recovering her memories from her previous life, the heroine goes on a killing spree, causing a human tragedy and alienating everyone around her. She is purely evil, a natural-born villain who thinks she can do no wrong.

If anyone in this world is to attain the Dao, it can only be the heroine. If anyone can wield absolute power, it can only be her. No one else is allowed to stand above her.
