I've Cleaned Fish at the Market for Ten Years, and Now You Say I'm the Real Heiress?

[Alternate setting + System] Ye Xinghe had spent ten years gutting fish at the market when one day she was suddenly told she was the Su family’s heiress. But the truth brought her no benefits. Her biological parents refused to acknowledge her. The girl who had enjoyed a life of luxury in her place for 21 years stood before her, holding a beautiful dress. “Do you know? This dress costs more than your life. If you weren’t about to marry that good-for-nothing in my place, I’d never give it to you!” Ye Xinghe clenched her teeth, furious. While trapped in the Su household, she unexpectedly gained a wish-granting System. It could grant all kinds of wishes, but it had a bug: whatever she got, the fake heiress received twice as much. Ye Xinghe was even angrier. Even the System was picking on her! Still, the System wasn’t entirely useless, as long as she figured out how to use it. Ye Xinghe first wished to be kicked out of the Su family and gain her freedom. The fake heiress was kicked out twice and cried until her eyes were swollen. Ye Xinghe wished to bathe in water heated to 45 degrees, and that night the fake heiress was scalded by water at 90 degrees and rushed to the hospital. Ye Xinghe wished to weigh 100 pounds, and the fake heiress became a huge 200-pound woman. Ye Xinghe wished for her parents to fall into poverty and beg on the streets. The Su family went bankrupt overnight.
