An explosive blurb
A modern medical graduate student transmigrates into the body of a sickly legitimate daughter in a marquis's household, only to be framed by her half-sister with an exotic Western-region perfume?
Qiu Zijin gives a cold laugh, pulls out her silver needles, and strikes back, utterly shattering her hypocritical sister's scheme! She thought household intrigue was the worst she'd have to face, but then she got drawn into royal secrets.
Her blood can counter a hundred poisons and control venomous insects. A peacock-feather mark appears on her back, revealing that she carries the “bloodline of the Saintess,” coveted by two nations!
The Crown Prince frames her, Prince Su schemes against her, and the Rouran cavalry threatens the borders. Every step in the court's power struggles is fraught with danger! And then there's the haughty Prince Yu, who stays by her side to protect her: “Your blood, my life. I'll join you in turning this world upside down!”
With the Map of the Nine Provinces' Waterways in hand, she uses science to control floods, blows up ice coffins, and breaks venomous-insect plots, crushing every conspirator's schemes! From sickly girl to ruler of two nations, watch this poison-wielding doctor rewrite the fate of the realm and set the emperor's heart ablaze!
“This world is going to be mine!”
