Scraping by Under a Treacherous Minister

Chen Xianyu transmigrates into a book, becoming a cannon-fodder supporting female character who won't survive past three chapters. Her body is even frailer than Lin Daiyu's. She gasps after every few steps, coughs up blood in the wind, and faints at the drop of a hat. "..." With a body this useless, why even struggle? Just as she resigns herself to her cannon-fodder fate and lies flat waiting to die, her golden finger, the "Survival System," comes online. The System wants her to win over Su Beiye, the villainous, corrupt minister known as the "Jade-Faced Asura." "As long as the villain falls in love with you, lives and dies for you, and bangs his head against a wall for you, you'll live to be ninety-nine." [Hold hands: Stamina +10, Life +5] [Hug: Stamina +10, Life +10] [Kiss: Stamina +10, Life +15] [Do the deed: Stamina +10, Life +50] Chen Xianyu sat bolt upright on her deathbed. I can do this. I've got this. * Su Beiye is the young emperor's regent. He is ruthless and seeks to usurp the throne. He even dreams of destroying the other five kingdoms and plunging the world into war, offering mountains of corpses and seas of blood as a sacrifice. He lives only for power and ambition, until the day he meets Chen Xianyu. The world fears him, hates him, and wants him dead, but no one dares get close to him. The only one who does is the young woman he married, who approaches him of her own accord. She takes his hand, hugs him, kisses him, and teases him, stirring the strings of his long-dead heart. At last, he opens his heart and pulls her into his arms, rasping, "Have you already fallen hopelessly in love with me?" Chen Xianyu: "Yes. You've already sunk into my bones and been carved into every inch of my flesh. I live for you, and I'll die for you!" You might not believe it, but I'm only doing it to stay alive. Coming soon: Break Her Wei Longyin is reborn, back at the time she first met Xiahou Shang. He was lying in the snow, battered and clinging to life, looking wretched and pitiful. She kindly saved him, only for him to viciously grab her by the throat. Her instinct to survive made her gouge out his eyes. Later, Xiahou Shang murdered his father and brother, climbed a mountain of corpses and sea of blood, and became the one-eyed tyrant everyone feared. She, meanwhile, fell into the dirt and became his plaything. When the same scene plays out again, Wei Longyin would rather hurt herself than wound him and rob him of his chance to survive. Blood streams from her wrist as she shakily reaches her hand to his lips and gently says, "Don't be afraid. I won't hurt you." * Xiahou Shang was born with a handsome face, yet he was an outcast among the royal family. He had no sense of the world around him and was naturally cruel and wanton. People saw him as a poisonous snake, a monster, and no one wanted him to live. At death's door, he thought he was facing betrayal and assassination. He never imagined he would find the only light of his life. To keep that light all to himself, he gave in to every ounce of his obsession and madness. "Yinyin, only by my side can you find your final resting place!" Your salvation in the abyss lit up my world. P.S. The male lead is a beautiful, powerful, tragic madman. The dynasty is fictional; all logic serves the plot. Theme: Perseverance
