Shen Qingdai, a modern master of traditional Chinese medicine, opens her eyes to find herself the doomed legitimate daughter in a tragic novel, sentenced to death from the start.
Faced with the poisoned wine offered by the regent who holds the court in his palm, she swiftly seals her acupoints with a needle, fakes her death, and escapes, awakening the Healing System along the way.
Her half-sister sets a trap at a banquet? She saves the old madam with a single needle, then sends her half-sister off to the countryside.
The regent treats her like a prisoner? She cures his wet nurse's long-standing illness and, while she's at it, puts an end to his insomnia.
The patients she casually saves turn out to be the empress dowager or the emperor, a prince or a great general.
Then a plum-blossom jade pendant reveals her true identity: the last survivor of the previous dynasty, bound to a blood feud.
She holds up a silver needle and sneers. “This needle can send you to the next world or bring you back to life. Which will it be?”
The regent pulls her into his arms. “I choose... you.”
[A healer's heart, but don't provoke me. If you do, I can save you, or send you on your way.]
