The Dragon's Flower: Novice Green - The Dragon's Flower, #1

After an accident, Le Xiao Ting found herself possessing a small cannon fodder's body inside a novel she had been reading. But why did the storyline going to a different direction than what she had read? Xiao Hua, the body she was currently possessing, would die if she continued staying around Princess Long Lian and the Third Prince Long Zhu, but her attempted escape failed. Xiao Hua was supposed to be the princess' maidservant in the novel, but she ended up as the Third Prince's personal maid instead.
Not only that, her expected days of being a hardworking servant did not happen, but ended up being the most leisurely maid that's very much favoured by her new master.  The change was centered on the Third Prince, who was supposed to be an unambitious prince and cannon fodder, but he did not act according to his script. He went wild by arming himself with power and gathered the heroine's supporting male leads to go against the hero and heroine! Did she actually transmigrate into a fanfiction version of the novel instead of the original one? [Book 1 of 9 The Dragon's Flower]
