I Am the City's Great Villain!

The villain is as unkillable as a cockroach, living longer than both the male and female leads. Crucially, she's always there to annoy people. She's as powerful as a leader, so it's best if she's the female lead; don't write any other female leads, because the villain is truly formidable.

What kind of garbage is this? Almost not a single sentence makes sense.

The writing is messy and the style needs improvement.
