Su Qian, the world's top poison medicine expert, once traveled through time and became a poor bride who was disfigured and stuffed into a coffin for burial. In the coffin, she conveniently saved a dying "sick man" and became her husband. The whole family was waiting for her, an ugly girl, to die together with a sick man. Little did he know that she possessed a heaven-defying medical dimension. She could save people with her left hand and plant poison with her right hand. Little did they know that her "sick" husband-in-law was actually a powerful regent, ruthless and full of plans. Su Qian just wanted to make enough money, heal her face, and then sell this troublesome man to Nanfeng Pavilion for money. Until one day, he regained his memory and blocked her in a corner with a dangerous look in his eyes: "My beloved concubine, I heard... You want to sell me by the pound?"
