My College Entrance Exam Spot Was Stolen? I Reported You and Sent You to Prison

[Eighties setting + System + pocket dimension + family drama + wicked heroine + underdog comeback + no self-sacrifice + feel-good power fantasy + unhinged fiction] (How do you survive when surrounded by awful people? Fight fire with fire and become the worst of them all.) A scheming little white lotus from the apocalypse, reborn into a battlefield from the start. The System that drops out of nowhere is a real piece of work. It betrays its Host, so kill it! Her stepsister steals her university spot, while her stepmother sells her off to an old official with three children as his bride. She hacks at her husband with a kitchen knife and kicks the wicked old hag. As long as she has no morals, not even a wall of righteousness can stop her. When the old official gets beaten by his wife, the commune steps in to mediate and calls it mutual domestic violence. She keeps herself clean, gets him locked up, and divorces him without hesitation. Her stepsister, who took her university place, has latched onto a rich man and is untouchable. Only then does she learn from the damn System that she has transmigrated into a book and her stepsister is the heroine. She takes down the System, reclaims the opportunities meant for her, and makes connections throughout the business world, determined to become a female business tycoon!
