Should a Vilainess snake eat a fox?

She was reborn into an ancient historical world where demons and celestials existed. In particularly, an oriental themed fantasy novel of the Xianxia genre that was created back in her grandmother's maiden days.

Reborn into a snake demon family that particularly prefers white scales over her green ones. They adored her little siblings who are red eyed white scaled snakes, especially her brother who is a male heir. Yet they neglect her due to the color of her scales.

What? Moldy?? HER SCALES ARE JADE GREEN ! They're not moldy!

What? they also tried to groom her sister to be a sacrificial bride too??. Hell no.

Alright, since they never wanted her in the first place, let's just burn their warehouses, run away and steal their worthy treasures and techniques. Oh, let's kidnap my little sister too to tag along.

Years later, she was doing so well providing all types of poisons and medicine for the black market to make their living. But then a sudden fox envoy came to visit, and he almost destroyed her business in mere days ?!.

Wait a minute, he's the henchman of the main villain in the story ?. The main villain, a demon king who almost destroyed the mortal world is being interested in not only me, but also my sister ?!. Bullshit, what a lame excuse to threaten me to surrender my skills. You just wanted to use me to catch the main leads right?!. And no, my sister is not for sale for such a low price.

What? Work or death? Your mom is dead! Forcing this grandmother of yours to do such a thing!. This ain't her first rodeo with this kind of stuff.

Tch, fine. I have no choice. I will do your biddings. But as the so called snake like b*itch, I will get my revenge. Starting with that cunning fox eyed jerk !
