Keeping a Low Profile as a Saintess in the Primordial Holy Demon Sect

Gender swap, a love-triangle bloodbath, survival in the Demon Sect, and a groveling ex chasing his wife. I transmigrated into a menial drug-tester for the Demon Sect, but one poisonous pill turned me into a peerless cultivation vessel coveted by everyone. The entire sect is full of experts at the Primordial Saint stage, and they all want to drain me dry. The chief senior brother wants to kill me to prove his Dao, the young master of the Shadow Hall wants to use me as a pawn, the Holy Son of the righteous path wants to trick me into being a spy, and the demon sealed in the forbidden grounds treats me like a toy... And me? A former office drone with zero combat ability, surviving on acting skills and a brain that actually works. Since you all want to use me, don't blame me for... turning every one of you into stepping stones beneath my skirts. Watch how this so-called “Holy Maiden” claws her way out of this demon's den and stirs up the whole world!
