In her previous life, she was the most dazzling legitimate eldest daughter of the General's Mansion, innocent and carefree, knowing nothing of the world. But her stepmother and half-sister conspired against her. Her mother died tragically, her little brother disappeared, and she was falsely accused of treason. In the end, she died with hatred in her heart, struck down by a blade.
Reborn in a single instant, she returns to the age of twelve. Her mother has just died, her stepmother holds power, and her half-sister wears a mask of virtue. Everyone thinks she is merely a frail young lady who learned medicine after suffering a long illness. They have no idea she carries memories of her previous life and has mastered both medicine and poison, transformed from the person she once was.
She uses silver needles to detect poison and turns medicine into a weapon. When her stepmother sends her tonic, she plays along and turns the tables. When her half-sister lays a trap, she springs it in reverse. When a plague ravages the capital, she disguises herself as a man and leaves the city to treat the sick, saving countless lives with the Ghost Doctor's needle technique and making a name for herself in a single battle. When strange illnesses run rampant on the frontier, she travels a thousand miles to the military camp, defeats the enemy with her mastery of poison, and earns the soldiers' respect as the "Divine Doctor."
She advances carefully, fighting her way from the inner strife of a grand household to the political games of the imperial court. The truth behind the late empress's death, the astonishing secret of her own birth, and the ultimate charge entrusted to the Ghost Doctor's heir: through the layers of mystery, she and the cool-headed, perceptive Seventh Prince, Xiao Jingheng, go from testing each other to entrusting their lives to one another.
A healer can bring the dead back to life and restore flesh to bone. A poisoner can kill an enemy without a trace.
And she, peerless in both medicine and poison, saves people from peril and kills from a thousand miles away.
The legitimate daughter has returned, and the phoenix star has claimed its place. In this life, she will reclaim, one by one, everything she was owed. Anyone who harms those she loves will be hunted down, no matter how far away they are.
