After dying, Jiang Lan transmigrates into a book and becomes an overbearing female CEO.
This CEO isn't the heroine or the villainess. She's just cannon fodder.
In the original story, this cannon-fodder character throws her weight around because her grandfather is a CEO, her father is a CEO, and she's a CEO herself. She picks fights with everyone, from the male and female leads to the supporting characters. Readers find it satisfying, while also remarking on what a complete idiot she is.
In the end, the overbearing female CEO makes so many enemies that the male and female leads join forces with the supporting characters and drive her company into bankruptcy.
Jiang Lan arrives with a face-slapping System, only to find herself on the brink of bankruptcy: ...
Looking at the twenty million in her bank account, Jiang Lan thinks for half a minute and finally decides to forget it. She'll just pack up and move back to the countryside.
The face-slapping System, frantic and hopping about: Host, I've got all kinds of dirt on the male and female leads and the supporting characters. I guarantee you'll succeed at face-slapping them. You have to make them eat their words!
Jiang Lan: When will revenge ever end? The world is so filthy because things like you exist.
The face-slapping System: Pah! Why didn't you say that back when you were making everyone eat their words?
Jiang Lan: That's because they didn't know how to talk. I was just teaching them how to speak to people properly.
