The Most Efficient Cultivator

[The author's ongoing story, Fellow Daoist, May I Borrow Your Spiritual Root to Copy It?, is available in the author's works. Please give it a read!] Lin Shuang, a modern top student who values efficiency, wakes up in a cultivation world after traveling there overnight. From the start, her heart and bones have been ripped out, and she is dead. But after waking, she can't remember who her enemy is. All she knows is that she cultivates at an extraordinary speed, and she must be the enemy's sacrificial offering. Afraid of being killed and having her bones dug out again, she starts a life of laying low while seeking revenge. She poses as an outer-sect laborer, a good-for-nothing disciple who cultivates slowly and has no talent in the eyes of her fellow disciples. The upright, stern senior steward brother: "If you don't improve, the rules say you'll have to leave the sect." The genius junior sister who wants to be a domineering CEO: "Senior Sister is so weak. If she goes out, evil cultivators might use her as a sacrifice to the heavens." The inner-sect senior brother, an assassin ranked number one who loves money more than life: "Hmph, what a waste of resources. You could give those spirit stones to me!" Disciples from rival sects all make fun of her. Lin Shuang takes it all in stride. But when they turn their backs and fall into danger, the hundredfold spiritual energy she has suppressed for ten years erupts all at once, smashing a Golden Core evil cultivator into a crater. Lin Shuang: Are you all right? Sniff, Senior Brothers and Sisters, I'm so scared. Everyone: ?! Years later, rumors spread throughout the cultivation world about a powerful elder with something wrong in her head, who disguises herself as a Qi Refining female disciple every year. Lin Shuang: That's not true. I really am at the Qi Refining stage. I'm just a diligent Qi Refiner with a reasonable disguise. * The nine-tailed fox demon, Huangfu Yuan, is descended from an ancient bloodline and can help human cultivators break through. When he was young, eight of his tails were brutally cut off. In this life, he hates human cultivators most of all. So he hides his identity, pretends to be gravely ill, and gets close to his enemies, intending to die alongside the ones who destroyed his clan. But a woman in green, pretending to be delicate, happens to witness him pretending to cough up blood while crushing an enemy's neck with his claw. She holds up the corpse of an evil cultivator in her hand and gives it a little shake. "Oh, what a coincidence. You're pretending too... Ahem, ah, the sunlight is so bright. I didn't see a thing~" The Nine-Tailed Demon King: "..." The male and female leads start by plotting against each other, then support one another and take revenge together. It's something of an ensemble story. [Well-rounded, top-student planner who controls a yandere vs. world-destroying, yandere nine-tailed fox king] Theme: Treasure your time
