After Being Bound to the Exchange System, I Went on a Killing Spree

I was the most talented woman in the capital, yet I was drowned for giving birth to a heterochromatic bastard child of unknown lineage. After death, my soul drifted back to the Vice Minister's mansion, only to learn that my mother was a transmigrator with a "swap system." She used this system to exchange my stunning beauty, my prince husband, and my unborn child for my younger sister. My sister was her illegitimate child with her beloved, and she had poured everything into raising me, only to sacrifice me for her sister. I was reborn from immense hatred and resentment. In this life, I will use their most prized "swap" to drag them into hell with my own hands! 1 "Mother, today your daughter untangled the jade pendant of the Prince of Jin..."
