Douluo Dalu: The Wicked Woman Is Mean and Twisted, So Bring It On

[Villainess with no morals, against the protagonist group, uses anything and anyone, an overpowered golden finger, plenty of original worldbuilding] Yue Wu merely complained about the plot, then unexpectedly found herself in Douluo Dalu. From the start, she was at odds with the heroine, Xiao Wu. The power of her hatred unexpectedly grants her a Second Martial Soul, allowing her to wield calamity itself and become a walking natural disaster in human form. From that day on, anyone who dares cross her suffers for it. Oh, you say you never provoked me, but you got caught in the crossfire anyway? You wonder if someone as awful as me feels any pangs of conscience? Nope. I have no morals and no conscience. Everyone she despises will be cast into the depths of hell forever. Everyone she loves will ascend to the Divine Realm.
