Su Wan, a top cardiothoracic surgeon, accidentally traveled through time after a series of surgeries and became the cannon fodder Princess Jing in the ancient novel who could not survive three chapters - Su Wan.
The original owner was a wedding bride given by the emperor to the frail Prince Jing, Xiao Jinyu. On their wedding night, she foolishly committed suicide and ended up being poisoned and drank to death. When he opened his eyes, he was in a desperate situation. Su Wan knew that he was in a chess game of certain death, and the only way to survive was to change his fate against the will of heaven.
Relying on her medical skills that were ahead of her time, she used silver needles to rescue Xiao Jinyu when he was about to die, and brought this scheming, sickly and cruel powerful minister back from the gate of hell. He originally wanted to save his life and stay away from the dispute, but due to his amazing talent, he was firmly targeted by Xiao Jinyu, and became his only healer and weakness.
Faced with the frame-up of White Lotus's female partner Liu Ruyan, the prince's wooing, and the emperor's suspicion, Su Wan worked step by step, tearing apart the conspiracy, outwit the deadlock, and used medical skills to gain a foothold. But just when she thought she had control over her destiny, northern barbarians raided her, the border war situation changed drastically, and the original plot completely collapsed.
The sickly prince unexpectedly volunteered to go on an expedition and was caught in a sea of fire, with his life and death uncertain. Su Wan, who has lost the protection of the script, is no longer a passive cannon fodder for survival. She uses her medical skills as a blade and wisdom as a shield, vowing to break through the shackles of imperial power and travel thousands of miles to save her husband. In the chaotic world of power and conspiracy, she shares life and death with Xiao Jinyu and rewrites the fate of the country.
