During the ten years in Zhongnan Mountain, Lu Ye learned not only the medical skills to save people, but also the secret method of killing monsters.
When he was ordered to join the world by his master, he thought it was just a security mission, but he stepped into the quagmire of the Netherworld Sect's management. The daughter of a wealthy family is a "Yiyin" who was raised by others, the university laboratory echoes with the wails of the innocent souls, and the girl who met by chance on the train actually has a rare "Xuanyin constitution"...
Silver needles can determine life and death, and talismans can lead to the underworld.
When the "mountain doctor" who saves people picks up the "sharp blade" to kill evil, what he wants to cure is the disease of the entire city.
"My name is Lu Ye, Lu from the land, Ye from the wild. I can cure your disease. I can also take in your soul."
