As the "poison fairy" who is feared by the world, Hua Jianqiu is good at two things in his life: making poison and making people die. However, a piece of good news and a piece of bad news hit her head at the same time. Good news: She committed suicide and was poisoned by the strange poison "Midnight Snow", which cannot be saved by gods. Bad news: The only antidote to this poison, "Ambergris Jade", is in the hands of Prince Duan, who is famous for his "Smiling Yama". In order to survive, the No. 1 Poison Immortal in the world was forced to wash his hands and make soup, and became a "frail and sickly" guest in Prince Duan's Mansion.
