I became a maid of the Sacheondang Clan, the family of poison and hidden weapons, completely out of my mind.

One day, I woke up inside a martial arts novel.

The body I possessed belonged to a humble laundry maid of the Sacheondang Clan, feared for their mastery of toxins and covert weaponry.

I thought I was just a lowly servant, but something about this body feels unusual.

From Tang Jung, the Poison King and grand elder of the Tang Clan who has regained his youth, to Namgung Hwi, the young master of the Namgung Clan, all the major character in the novel keeps noticing me, and peace has become a luxury.

"Sohye, listen carefully to what I’m about to say. When I say I want to teach you, I mean it sincerely."

Before I know it, I become Tang Jung’s disciple, despite being only a maid, and begin studying literature and martial arts in earnest.

Can I really survive safely in this harsh martial world?
