[Cool, Cute Metaphysics Expert x Short-Lived Capital-Circle Heir; Transmigrate into a Book + Change Fate + Face-Slapping + Punish Villains + Redemption + Seduce Her Way to the Top] Jiang Wanci was just slacking off when she opened her eyes and found herself transmigrated into a book about a true and fake heiress, as the cannon-fodder sidekick to the fake heiress. In the original story, she helps the fake heiress do evil and steal the true heiress's luck. When she fails to get credit for it, she's murdered before the story's end. Seeing the true heiress's luck being stolen, she instantly takes down the metaphysics master behind it and gains a fangirl in the process. But before she can even leave, the male lead blocks her way. “How about we make a deal?” Jiang Wanci's cultivation has dropped back to beginner level, so she turns to leave. “I can't save your life.” But when the male lead reaches out to stop her, her cultivation starts shooting back up. She grabs his hand and answers without hesitation. “I'm coming with you.” - Everyone knows the capital circle's playboy heir is living on borrowed time. Then, during a livestream of a metaphysics variety show, the heir appears full of energy, hands on hips, trading insults with the street fortune-teller the show has hired. The whole internet is stunned! “What would a little girl like you know about fortune-telling? Get lost!” “My Aci can tell fortunes and draw talismans. What the hell do you know?” Later, the show's midnight adventure takes an unexpected turn when they encounter a real ghost. Everyone hides behind the trembling old Taoist. Only the heir tugs coquettishly at Jiang Wanci. “Aci, hold my hand, please. I feel awful.” Jiang Wanci, now carrying a whole person around, quietly recites, “Mystery of Heaven and Earth, root of all qi, be subdued!” The old Taoist's eyes widen. “What the hell? She made a formation with a single thought?!” Everyone else: “Didn't you say it was fake? How can you really do that?” - Jiang Wanci is greedy, lustful, and lazy. Pei Tingsong is rich, handsome, and hardworking.
