Kneel Properly, Prince. Your Princess Is a Master of the Occult

Su Qing, the Ghost Emperor of the Nine Hells, borrows a corpse to return to the mortal world and becomes the legitimate daughter of the prime minister's household. Her father doesn't care for her, and her mother died in childbirth. In the cannibalistic prime minister's residence, all manner of vicious people come looking for trouble.

Her aunt uses evil spirits to harm her. She brings out the Exquisite Tower and takes care of them. Someone abuses women. She takes care of them. After recovering all the evil spirits that escaped from the underworld, she prepares to leave.

Then a certain prince, whom she'd been using as a human power bank, latches onto her.

"We've missed each other for nine lifetimes already. Are you sure you still want to leave me?"

Su Qing: Huh? What's going on?
