She is the last medicine-bearer in the mortal world, with sacred blood in her veins that can cure any poison.
He is an orphan abandoned in a mass grave, with the world’s most deadly poison, the Heart-Devouring Gu, living inside him.
When Pei Yuan, a young medicine-bearer, rescues a boy from a pit of corpses, his body rotten and black threads crawling over his heart, she has no idea that the boy she raises on her own blood will become the key to bringing down an entire dynasty.
Ten years later, he has become the Marquis Who Guards the Nation, a man whose power dominates the court. And she has become the one poison in his hands that he cannot cure.
“A Yuan, they say you’re medicine, but you’re clearly my very life.”
But he doesn’t know that each of the 108 scars on her body was made to trade her life for his.
