Transmigrating into the novel, [The Emperor of Luck] Gu Xia received the despair villain system and became a small villain who is destined to be face slapped by the protagonist then eventually killed.

Having been through the plot thousands of times and being failed by the system every time, he finally snapped.

“System! What did I do wrong this time!?”

[Host, please calm down... There has been an error in the world that I have no control over. As an apology I can grant you extra rewards once you complete the plot!]

Gritting his teeth and having bloodshot red eyes Gu Xia finally had enough.

[I quit being the villain! Fuck the plot, fuck the heroine's, fuck the protagonist, fuck everyone, I just want to live my life without being face slapped! I QUIT!]

Unknowing to him all of the heroines could now hear his inner voice…

A conversation with a handsome stranger leaves Ariane chained in a cellar with a strange affliction. She soon discovers that the darkness of the nineteenth century’s Deep South hides many dangers. Mages, wolf shifters and the humans who hunt them play a risky game where to stumble is to die, all under the amused gaze of the apex predators of the supernatural world: vampires.

It is never healthy to attract the gaze of the aristocracy of the night. It takes much to survive in this merciless world, but Ariane will not let that deter her. The southern belle has a bite, and she is willing to learn and to grow in this hostile new world. She will use whatever means necessary to reclaim her freedom, be it guile, charm, or those intriguing new instincts that make blood so delectable.

This is a story of vampires as I believe they should be, with their strengths and weaknesses, with their remnants of humanity and the beast inside. Updates every Friday. Mind the tags.
