Quick Transmigration: The Villainess Is Poisonous

After waking up with a quick transmigration System in her head, Xia Fengguang is forced to travel through the worlds of romance novels. In a CEO romance, the heroine is an ordinary, sweet and innocent college student, while the hero is a devilishly charismatic king of the business world. In a martial arts story, the heroine is a lively, adorable healer and poison master, while the hero is the merciless leader of the demonic cult. In a fantasy story, the heroine goes from being a good-for-nothing concubine-born daughter to a cultivation genius rarely seen in a thousand years, while the hero is an exceedingly cold Demon Lord who is gentle to only one person... And she, the hero's fiancée, is beautiful, fair-skinned, and from a good family, yet in every world the hero fails to fall in love with her. Xia Fengguang smiles. A meticulous corporate elite, a sharp-tongued emperor of an enemy kingdom, a playboy young lord, a medical and poison sage who looks proper but is frivolous underneath... Aren't these men far more interesting than the hero?
