[Wuxia Crossover] My Senior Brother Is the Bat Prince

[The male lead is obsessive and unhinged, and turns dark later on.] Zhu Xiaozhen transmigrates into a book, entering the world of a wuxia novel. The original owner is the only daughter of the master of the Zhu-Wu Alliance Manor, a peerlessly beautiful heiress. She is the male lead's first love, the moonlight in his heart. But she pushes him off a cliff. Sob... Ding-dong! Congratulations, Miss Zhu, you've successfully bound yourself to a System. Miss Zhu is now the first Host of our company's newly developed Supporting Female Character System. This System is dedicated to fulfilling supporting female characters' wishes before they die. Once their wishes are fulfilled, the Host gets to make one wish of her own. The binding can only be removed after the mission is complete. Zhu Xiaozhen asks: What was the original owner's wish? The System shrugs irresponsibly: I have no idea. The System is practically useless and knows nothing, but it has a store that sells things you can't find anywhere in the world: mind-reading pills, regret pills, beauty pills... But everything in the store costs points to redeem. And to earn points, you have to complete missions and fulfill other people's wishes. #Zhu Xiaozhen: Senior Brother, what do you wish for? # "Would you like to have the most beautiful woman in the world? For example, me?" Her senior brother gives her a haughty, disdainful look. Later... On Bat Island, in a dim room. He holds a dagger and kneels before Zhu Xiaozhen. The icy blade traces her hands and feet, then presses intimately against her ear as he rasps, "Tell me... what is it they all like about you?" Zhu Xiaozhen answers fearfully, "...My face?" The next second, the gleaming blade presses against her face. Zhu Xiaozhen is about to cry: "..." The author is terrible at writing blurbs, so give the actual story a try. Theme: Any ordinary, unremarkable life can turn itself around.
