The retired master of martial arts lives in seclusion in the valley, guarding the medicine field with his daughter and living an ordinary life, just to protect his daughter from growing up.
But he didn't want his daughter to be accidentally exposed to the world because of her ability to talk to "ghosts".
Incidents happened one after another. In order to save his friends who were in danger, his father dispersed his family property and went to a foreign country to look for people. Unexpectedly, he was imprisoned and was never heard from again.
The girl relied on her intelligence, courage and ability to talk to "ghosts" to overcome life and death difficulties time and time again, gradually uncovering her father's dusty past, and also involved the age-old political disputes in the court.
