[Strong female lead, absolutely no romance, career-focused, not a self-sacrificing saint. The two female leads are equally important, not a couple. Some of the satire is exaggerated, to put it mildly. If that's not your thing, don't read.]
Every world has villains like these: noble-born but not spoiled, kindhearted but no pushover, clear about who they love and hate but never harming the innocent. They understand the bigger picture, and they're capable and responsible. Yet despite all their efforts, they're instantly eclipsed by the so-called protagonists' halo, and everyone dismisses their hard work and sacrifice.
There are also people who look down on women and smear and label them without even realizing it. They constantly oppress women, trying to profit from them. They delight in competing against other women and are experts at palace and household intrigue, yet they never think to, or dare to, compete against men.
Bai Qingcheng is the heroine of a melodramatic tragic romance, but she stays clearheaded and takes down the male lead. To rewrite her fate, she makes a pact with the divine Feng Yayang. Together, they travel to other worlds to help villains turn their lives around, fulfill their wishes, and serve up some face-slapping to the scumbags and wicked women.
So Feng Yayang watches as Bai Qingcheng tames angels in a fairy-tale world, ascends effortlessly in a cultivation world, and secures the throne in a fanfiction magic world...
Feng Yayang: Looks like you don't need my help. I'm going off to have fun. Call me when the mission's done.
Bai Qingcheng: ?!!! (completely baffled)
Bai Qingcheng: Whose System is this... Oh, right, a deity! How can you be so irresponsible? I want to file a complaint!!! (freaking out)
