Everyone Played Favorites, So the Real Heiress Cultivated the Path of Ruthlessness and Went on a Killing Spree

I was the real heiress, secretly switched by the steward on the day I was born. After being rescued by Daoist Qingwei, I cast aside distractions and devoted myself to the Ruthless Dao. Later, my birth parents came looking for me, but even as they brought me home, they warned me, “You may share our blood, but Mianmian has been our daughter for over a decade. Don’t think of competing with her for our affection.” My three older brothers despised me. “Why didn’t you just die out there? Even if you come back, we’ll never love you.” I only smiled at the little ghosts behind them. Why would I need the fragile emotions of the mortal world? They should worry about finding a more dignified way to die first.
