Reborn, the Young Lady Slaughters Everyone!

After being reborn, I discover I've become Su Fu, an ugly woman hated by everyone, the kind of person even dogs would bite! What the hell, what kind of second start is this? I was already made miserable by a scumbag man and a nasty woman, and now I've been reborn in the body of a loser! Luckily, she has a System to help her strike back. The System is great, but she can't use it all the time. It costs her money! Damn it! After that, Su Fu goes on a killing spree! Scumbag men, die! Nasty women, die! Idiots, die! Evil women, die! Evil men, die! Su Fu is going to kill everyone who hurt her! This world is already so freaking crazy, so why can't she go completely off the rails and kill in a rage?
