This Sword Spirit Just Wants to Lie Down, but the Host Curls up into a Sword Master

In the 21st century, Ling Xian, a social beast from the Tucao family, died suddenly and his soul entered the ancient sword. The sword master Yun Zhao is the legitimate daughter of a declining cultivation family. She has mediocre qualifications but is possessed by King Juan. She has a salty mentality, an inferiority swordsman, a guardian obsession, an immunity to poisonous tongues, a person who has realized the "Free Sword Intent", and a self-created "Lieping Sword Technique".
