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 housekeeper on the day I was born.

After Daoist Qingwei saved me, I cast aside worldly distractions and devoted myself to the merciless path.

Later, my birth parents found me. But even as they took me home, they didn't forget to warn me:

"You may share our blood, but Mianmian has been our daughter for over a decade. Don't think you can compete with her for our affection."

My three older brothers despised me. "Why didn't you just die out there? Even if you came back, we'd never love you."

But I just smiled at the little ghosts behind them.

The fragile emotions of the mortal world,

do I need that sort of thing?

They'd better start thinking about how to make their deaths look a little more dignified.
