She is the last soul-transferring person walking in the reinforced concrete jungle. She uses traditional Chinese medicine and acupuncture to save the lost souls in the world and heal the hearts that are difficult to heal in the world of mortals. When the ancient restrictions were broken and spiritual energy revived, sleeping demons and hidden sects emerged one after another, and the bustling city turned into a Shura field overnight. She originally just wanted to be a carefree doctor, but she was involved in a shocking conspiracy that swept through the three realms. From the quaint medical clinic on the corner of the city to the eternal glacier at the top of Kunlun, from the flashing neon lights of the bustling city to the turbulent waves of the sea of blood in the netherworld. She uses silver needles as swords, uses medical knowledge to prove immortality, kills decisively, and crushes the sky. When her compassionate heart was betrayed and her efforts to save the world became a laughing stock, she turned the needle into a blade and launched the most arrogant challenge to this hypocritical way of heaven! "This injection of mine can save people or kill immortals!"
