The Marquis's Abandoned Wife: Master of Medicine and Poison

The Su family's legitimate daughter, Su Mu, brings a fortune with her when she marries into the Marquis's household. She honors her mother-in-law, manages the household, treats her younger siblings well, and is generous to the servants, only to receive news that her husband is returning from the border with a princess from an enemy kingdom as his political bride!

Worse, the Marquis's household plans to demote her to concubine!

Su Mu finally understands that these ungrateful wretches will never change.

Her husband spouts grand ideals about his country while keeping concubines by the dozen behind her back.

Her mother-in-law uses the safety of the Su family to pressure her at every turn, trying to bleed her dry to support the Marquis's household.

Did they really think Su Mu couldn't live without the Marquis's household and its backing? She must divorce him!

The Marquis's household thinks a discarded wife like her will have no choice but to eke out a miserable existence. Little do they know she is a master of both medicine and poison, and the powerful nobles of the capital would go to any lengths for her.

The most troublesome of them all is Si Yucheng, commander of the Mingxuan Guards!

Su Mu kindly helps Si Yucheng detoxify, but unexpectedly, he wants her to help him relieve his desire night after night...
