In the world of cultivation, medicine and poison are at odds with each other. Qingyao, a descendant of the southern Xinjiang poison line, sneaked into the Xuanxiao Immortal Gate to steal the elixir to save his people, but he broke into the "sick" Yun Yi and coughed up blood. In order to save her life, she was forced to become the exclusive medical practitioner for this young man who seemed to be knocked down by the wind.
Yun Yi pretended to cough up blood and fainted all day long, while Qing Yao scolded the "short-lived ghost" while researching weird folk remedies. Little did he know that this "medicine jar" was actually an immortal king who descended to earth to overcome love tribulations, and secretly prevented her from being killed again and again. The two of them have their own thoughts and think that they are "plotting" each other, but they have secret feelings as they get along day and night.
It wasn't until Qingyao was on the verge of death from poisoning and Yun Yi wiped out the devil's cave with a single sword, her whole body filled with immortal energy, and sneered, "Even the King of Hell can't take away my people," that she was shocked to realize that the "weak young man" she had been fighting against day and night was actually a peerless strong man. When the truth about love emerges and the shackles of fate between the poison and the doctor lie in front of them, how should they break the predicament, protect each other in the whirlpool of conspiracy and fate, and write a legend of the love between the poison and the doctor?
