My elder half-sister is the greatest physician in the capital, yet she can't cure the Crown Prince's chronic illness.
I was sent to the Eastern Palace to serve as a medicinal catalyst, and my sister laughed that I wouldn't live three days.
But after I casually stuck in a few needles, the Crown Prince was able to get out of bed and walk.
My sister tore up the medical text. "You don't know the first thing about medicine!"
I pulled out my family's ancestral Manual of Imperial Poisons. "It's true that I can't cure him, but I'm even better at making His Highness... sick in just the right way."
