Ling Qingyuan, a peerless medical fairy from the Nine Heavens, accidentally touched the ancient forbidden formation while refining the "Eternal Life Pill", and her soul passed through the body of a wealthy daughter of the same name in the 21st century. The original owner was recognized as a "walking hormone", but due to a family marriage, he was forced to marry Lu Shiyan, a school girl who was rumored to be cold, sinister and unsexy. He accidentally broke his brain while escaping from the marriage, and when he woke up, he became a "sand sculpture beauty" with his own medical fairy buff.
Ling Qingyuan possesses ancient medical skills, but she uses them to treat her classmates' "class drowsiness", prepares "secret anti-hair loss medicine" for the dormitory aunt, and even uses acupuncture to help a paralyzed stray dog cross the finish line at a sports meeting. She has incredible looks, but she always does stupid things such as using lipstick to draw charms to repel mosquitoes and using a diamond necklace as a scraping board. Lu Shiyan, on the surface, is a cool school boy, but in fact he is a hidden technology boss. His family owns a company that can build spaceships, but he is driven to the verge of collapse by Ling Qingyuan's nonsensical operations every day - his AI robot was changed into an "automatic snack delivery machine" by her, his limited edition sports car was used by her to sterilize stray cats, and his carefully prepared confession was dismissed on the spot by her as an "exorcism ritual".
The two bonded in the chaotic campus life. While Ling Qingyuan used her medical fairy skills to unlock various strange tasks (such as helping the principal to find the lost dentures and treating the school beauty's "Versailles allergy"), she was forced to deal with the family's business conspiracy, Lu Shiyan's strange relatives, and the sudden appearance of a "previous love rival" (a thousand-year-old white fox who had been trained to become a spirit, possessed by the school mascot doll).
