In her past life, Shen Changge had her life-saving blood ginseng stolen by Hua Cheng. Her mother died of illness and her father suffered disaster; she was betrothed to a beggar, and died miserably after assassinating Hua Cheng. Reborn back to the node when the ginseng was intercepted, she prepared a poisonous fake ginseng for Hua Cheng to snatch away, splitting the real blood ginseng into three.
