The Cannon Fodder's Villainous Ascent

Woke up starving, locked in a lavish room, I discovered I was the tragic cannon fodder of a dog-blood romance – betrayed by my family, abandoned by my fiancé, and destined for madness and ruin. This fragile body and humiliating fate were supposed to be my end. But I am Ruan Tang, the ruthless Apocalypse Queen who built an empire from scratch and incinerated zombie hordes. This 'innocent victim' role? It chafes. My new mission is to fulfill the original owner's last wishes, but my 'helpful' system is panicking because my personal brand of 'justice' involves absolute, brutal domination. They thought they could break me. They don't know the calamity they just unleashed, a villainess who can't stop winning.
