In the Second Generation of the Trench, He Changed To the Ruanfan Script - Chapter 33:

I had transmigrated to a world full of magic. To ensure my survival, I have to cross-dress as a female so I don't get in trouble. This is the story of me tackling everything that gets in my way.

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.

Before her rebirth, she was abandoned by her parents, then murdered by her seemingly pure but vile younger sister. After her rebirth, she kicked all her scum boyfriends to the curb and began a campaign of abuse against the superficially perfect. Rumors were rife on the internet that Qin Sheng was a kept woman? A bunch of computer nerds, "Let's hack the keyboard warriors' computers." The first director, "Boss, have you written the script yet?" The medical expert, "Sheng Sheng, our research institute will give you 100 million. When will you be able to join our team?" A famous painter, "Sister Sheng, take me along when you hold your art exhibition." The CEO of a billion-dollar company, "Boss, when are you going to publicly disclose your identity?" Finally, a big boss pulled Qin Sheng into his arms. "Sheng Sheng, I've transferred all the assets under my name to you." Netizens, "?? This world has suddenly become crazy?" She was a business genius, a computer genius, a legendary screenwriter, a legendary painter, and a legendary medical expert. It remained to be seen how she would create flourishing prosperity. (The male protagonist has a propensity for recognizing bitches, but is infinitely sweet and doting to the female protagonist!)

Gu Man, who transmigrated from ancient times, woke up in the body of the Gu family’s second daughter.

As soon as she woke up, she saw the fiance of the original body who had hooked up with her stepsister. Faced with the scumbag’s confident questioning, disgusted gaze and a slap to her face, Gu Man’s reaction was to return a fierce blow to him. She hit him until he was dizzy and knelt to the ground, his lower body covered in cold sweat. Gu Man only realized that a video of her walking into the room had been leaked after she left, and the matter had begun to spread rapidly.

Countless people insulted Gu Man and called her a mistress.

Faced with a two-faced stepsister, a malicious and deceiving stepmother who climbed her way up from being a mistress, and a father who couldn’t tell wrong from right and treated her as more of an adopted daughter, as well as those stupid onlookers who didn’t know the truth of the matter and called her a country girl… Gu Man ignored them all.

The top scorer in the college entrance examination, top hacker, divine doctor, financial tycoon…

All kinds of identities were attached to a single person. Gu Man relied on her own strength to ruthlessly slap them all back in the face!

The noble Xiang family’s eldest son, a powerful man in the capital, even declared to the public that his wife was mischievous, and that he would take the blame if she made a mistake.

Just when everyone was wondering who this sweet wife of his was, the entertainment headlines published a photo of him holding his sweet wife as they walked in and out of a high-end hotel. The woman in the picture was Gu Man!

Xiang family’s son: Everyone, meet my wife!
