I am Nan Jingjing, the seventh prince of the emperor, but I was demoted to a secret guard.
>On the day my mother betrayed the country and ran away, my father personally pushed me into hell.
>All the princes treated me as a human punching bag, and the leader of the secret guards used torture tools to teach me "atonement".
>Only by eavesdropping on Master's class can I remember that I was once a human being.
