Yan Xi was the eldest young lady of Beiqiao City’s top four families, the Yan family. Despite her talents, she was sickly and destined to die young. She was an unattainable dream girl for many.

One day, she had a dream, and the setting was in a novel. In the novel, for the sake of alleviating his pain of losing his wife, and soon his daughter as well, her father adopted a girl named Chen Xiangxiang who looked just like her. The girl was docile as a deer and very therapeutic, which made her all the more lovable. This girl became her substitute, and after a series of heart-wrenching incidents, everyone, from her father, brother, fiance, to her friends, they all doted on this girl. Meanwhile, she, the real rich daughter, was schemed against. After being disfigured, she jumped from a building and fell to her death.

Now, she returned to the moment when she was just discharged and before the tragedies happened. She lowered her head and looked at the person before her. She smirked. This time, she would control every development, and those who intended to harm her could forget about escaping.

Yu Linglong is the shu (born of a concubine) daughter in a general’s family. Since her mother was only a tribute dancer, her position is the lowest of the low. She used to live with her mother outside the father’s residence, and they only received some monthly money from him. He didn’t bother seeing them. But when her mother dies, she moves into the general’s residence.

The general is a very irresponsible and violent man. He doesn’t really get attached to women, just letting his lust dictate his actions. His wife is a jealous woman, who killed one of his previous concubines, because he doted on her too much. She similarly wants to get rid of Yu Linglong, in part to vent her frustrations over her husband’s cheating habits.

Because the sixth miss – the general’s legitimate daughter, was bitten by a snake, she needs detoxification. The cure was apparently getting poisoned by scorpions, to fight one poison with another. But since she’s already weak, they decided it would be better if she drank the blood of someone poisoned by scorpions instead. The general’s madam naturally decided to use Yu Linglong’s blood. During the process of getting bitten by the scorpion, the original timid Yu Linglong died of fright (and maybe poison? it’s never made clear). Then Yu Mei takes over her body.

Yu Mei is a modern woman. She was some mafia boss, so she’s very capable with fighting and overbearing attitude. She died because the man she fell in love with betrayed her and killed her. So she doesn’t trust easily afterward.

Since she took over Yu Linglong’s body, she refuses to adapt to the circumstances of a lowly illegitimate daughter, and uses her violence to fight for a peaceful life, where no one will challenge her and plot against her. Basically, she beats them up into submission. In the meantime, she acquires a tail – a very persistent prince, who only seems to stick to her harder, the colder she treats him. Did ancient men have such heavy tastes, she wonders.
