Pharmacist Duan Yao, who shocked the world, dies overnight and transmigrates into the body of a concubine-born daughter.
She is forced into a rush wedding to bring good fortune, marrying a rooster, and she puts up with it.
But that bunch of powerful nobles dare to throw their weight around over her?
With poison needles in hand and unmatched pharmaceutical skills, she can beat the nobles and treat the unruly commoners.
A woman is having a difficult birth, and they ask whether to save the mother or the child? Duan Yao steps in, and both survive.
Disaster ravages the land, and they want to slaughter and burn the refugees? Duan Yao speaks a word, and peace returns to the world.
The world once bullied and mocked her, treating her as a laughingstock. Only that short-lived man refuses to let go, even threatening to have children with her?
"Wait! I healed your leg and cured your poison. Didn't you promise to give me my freedom?"
Zong Li picks her up and tosses her back onto the bed. "I'll give you everything you want, except one thing: you can't leave me."
Duan Yao suddenly feels that she saved a man and then... landed herself in a world of trouble.
