In late spring in the south of the Yangtze River, there was a heavy rain, and a thunder struck the prelude to fate. Medical girl Su Qinghuan took shelter from the rain in an abandoned temple. As soon as she put down the medicine box, she saw three dead men in black with poisoned crossbow arrows lying outside the door. What they desperately protected was the seriously injured and poisoned General Xiao Jinghan. His brocade robe was stained with blood, his face was green and black, but his eyes were still as sharp as cold blades.
Su Qinghuan wanted to turn around and leave - he was the one she vowed not to save after the blood feud between her family and country. But the doctor's benevolence cannot compete with the stubbornness of that dying glance. She saved him because of medicine, not because of her heart; she hated him because of his past, but she couldn't hide her emotion.
However, saving one person can lead to a game. The appearance of Xiao Jinghan revealed the tip of the iceberg of the undercurrent in the court, and also opened up the mystery of Su Qinghuan's life experience that had been buried for many years - she was not an ordinary medical girl, but an orphan from the previous dynasty. When the heart of medicine and the bones of war clash in the wind and rain, when national hatred and personal love dance on the tip of the knife, they make progress step by step, but they sink step by step. Is love an antidote, or a deeper poison? In this life-and-death chess game, who can escape unscathed?
