Findimg the Murim Manhwa

Does anyone know the title where the femald lead was reincarnated as a child of murim clan. She has 2 uncles one who has madness, the other one always sleeps. Her father has disease where he keeps on forgetting.

She can diagnose when she submerges people in water and the herbs that she needs will show how to cure that person. She tried to diagnose her father but no herbs appeared.
