Asking the Dao Costs Lifespan

Fifteen-year-old Zhang Fan has a nose that can smell the origin of medicinal herbs, and a jade he shouldn't have picked up. The jade is called the Asking the Dao Stone, and it lets him see all things as they truly are—provided he's willing to trade his life for it. Each use whitens a fingernail and shortens his lifespan. He could have gone forever without using it, continuing to slice herbs, dry herbs, get flicked on the forehead by his senior sister, and listen to Uncle Su explain the natures of astragalus and poria. Until that rainy night, when the demonic path stepped into Qingyang City. His senior sister pushed him into the secret passage and stood before the door with her sword drawn. Uncle Su went alone to the city gate. Three Foundation Establishment cultivators—nothing was left of them. — Description from novelcodex.orgFull novel: Asking the Dao Costs Lifespan — read the rest free on N​o⁠v​e⁠l​C⁠o​d⁠e​x⁠.​o⁠r​g⁠
