Lin Xuhe, a modern medical student, transmigrates into the body of the General's Manor's legitimate second daughter. She only wants to live in peace, but instead finds herself trapped in a thorny nightmare: the emperor fears the General's Manor has grown too powerful, her adopted sister harbors murderous intent, and her father, stationed at the border, has to sell off the family's ancestral property just to pay his troops. Armed with her knowledge of poisons and warfare, she vows to change her family's fate.
