I Took in a Wicked Woman as My Stepmother, and My Cruel Family Learned Their Lesson

【Farming + transmigrate into a book + System + Villainess】 Chen Shuyan unexpectedly transmigrates into a novel she had read, becoming the book's vicious cannon-fodder supporting female character. Weighing over two hundred jin, she is supposed to marry a rooster in a wedding ceremony from the start. She laughs. She snaps the rooster's neck, smashes up the scumbag's family home, and gets back the silver the original owner spent on him. I'm the village bully, a villainess in my own right, and your family humiliates me like this, then expects me to work like an ox and a horse for you? And after you make it big in a few years, you'll poison me and marry your white moonlight? Keep dreaming! “Congratulations, Host. You've unlocked the Cannon-Fodder Supporting Character's Fate-Reversal System. I'm your assistant, Xiao Yi.” Who? Who's talking? I transmigrated into a book and got a System too? What a deal! Wait, Chen Shuyan discovers that she has not only got a System, but superhuman strength as well! Then why should she be a cannon-fodder supporting character? She's going to be the heroine!
