The Yun Family's Ninth Child is an Imp! YFI

Yun Jiu was an ace special agent, but after escaping from her organization, she ended up transmigrating into the body of a girl called Yun Chujiu.
And she was... the weirdest girl in Ye City...
Useless, ugly, trash who can't cultivate, ungrateful wretch who backstabbed her adopted family for the enemy family.
But excuse me, I'm ugly?! I'll turn into a butterfly and blind all of you with my beauty!
I'm TRASH?! I have celestial lightning in my hands! I'll roast all of you to a crisp!
I'll walk across the lands with my sharp tongue as my weapon, and you can all fawn over me!
But a certain supreme lord just held his weapons and cut down all of the people who admire her...
And a certain girl just smiled.
"If you cut down my admirers, I'll destroy your admires. We're both evil wretches, if we're together, aren't we just a match made in hell?"
