Cutting Bones to Listen to the Qin

[Vicious adoptive mother × blackened and vengeful stepdaughter × all villain endings] I am the most well-behaved second young lady in the Shen family, and I am also the sharpest knife in my adoptive mother's hand. For ten years, I watched with my own eyes how she "carefully arranged"—— The most beautiful sister in the capital was disfigured and married into a high family, the talented princess became foolish and happy, the sister who loved swords the most had her hand tendons broken by my own hands, the singer with a golden voice was poisoned and given away... Until that day, I stood in front of my adoptive mother holding a knife. She gently wiped the blood from my face and praised with a smile: "Good boy, you finally avenged your mother." I feel like falling into an ice cave. It turns out that even I, the avenger, was raised as a tribute by her to pay homage to the dead souls. · The hypocritical adoptive mother is actually the mother-killing enemy ·Sisterly love on the surface but killing each other secretly ·High-ranking ladies collectively encountered "accidents" ·All living people are worse off than dead
