Dan Mok-ryeon, the eldest granddaughter of the Danmok family, awakens after 7 years. Strange messages begin appearing before her, revealing a dire situation: [Maintain your spiritual energy below 50. If this state persists for more than two months, death will result.] As the heir to a martial arts clan, she can't cultivate internal energy and must somehow release the energy building within her. But when she raises chickens, they become phoenixes; when she makes rice cakes, they become elixirs; and when she fans herself, the air purifies. "I'll eliminate anything that hinders my longevity!" She sets out to rebuild her failing clan. Just as she begins, she encounters Hwarun, the future young master of the Machon sect, who becomes her servant. He's even two years younger than her! With unexpected events piling up, will Mok-ryeon succeed in reviving the Danmok clan?
