I Met My Beautiful Online Date in Person from the Start, So Why Is She a Wicked Cultivator?

[Villain + System + Invincible + Comedy + Ruthless + Eradicate Every Last One]

Male lead: His Villain System absorbs attacks from the righteous path.

Female lead, demonic cultivator: Her life-bound magic weapon is a long-handled scythe that absorbs corpses and souls. (Isn't that basically a Ten Thousand Souls Banner?)

Seriously, I was just meeting up with someone I met online. I was happy enough that it wasn't a disastrous first meeting, so how did I end up with a demonic cultivator? And now I have to rack up spell power by killing people? Is this really going to work?

My demonic-cultivator girlfriend gave me a cultivation manual, but before I even got around to practicing, I suddenly awakened a Villain System? And it can only absorb attacks from the righteous path? So I'm really supposed to team up with a demonic cultivator, huh!

I've spent so long building up spell power for my demonic-cultivator girlfriend, and now we've finally opened a space passage. Where the heck have I landed? Why isn't this a cultivation world brimming with spiritual energy? Why am I greeted by a battle between elves and the undead? Well, fine. This time, I can be a villain who slaughters everyone without breaking the law. Elven King, High Priest, Paladin Commander, heh heh heh, come and become my spell power!
