Evil King's Favorite: Ghost Doctor Mad Concubine

She is the cunning and ruthless dark night ghost doctor. After a sudden transmigration, she becomes a waste of a woman despised by all. She contracts ancient divine beasts, cultivates heaven-defying divine techniques, and dazzles everyone's eyes. With poison pills and potions in hand, anyone who dares to bully her is courting death! What are nine-grade elixirs? Her cute pets eat them like candy. Being able to refine medicine, she is just that willful! He is the peerlessly beautiful and bewitching Night Prince, and the world believes him to be cold and ruthless. But why is he so difficult to deal with, like a lingering spirit, in her eyes? "What are you staring at me for?" "This king is thinking, when will you officially become this king's woman." A fine needle pressed against his waist, and she smiled: "Sir, impulse is the devil. If this potion is injected, you can only be a eunuch for the rest of your life!"
