Thrown in Prison from the Start. What's Wrong with Going a Little Crazy?

[Face-slapping, scumbag-crushing power fantasy with a strong female lead + a violently unhinged heroine + a scheming, doting husband + marriage first, love later] Jiang Yan, a starving ghost who had wandered the underworld for over a thousand years, transmigrated into a novel where everyone was evil. From the start, she stabbed her fiancé's beloved, and he sent her to prison. “Just kneel down and apologize to Yaoyao, and I'll let you off.” Jiang Yan turned around and married into the family in place of someone else, marrying a man in a vegetative state. She beat him until he couldn't get back up. “Eighty million, and we're even. Otherwise, I'll beat you up every time I see you.” Her brother-in-law disrespected her. “He's a vegetable. He can't give you anything. Why don't you come with me? I promise I'll make you happy every night…” Jiang Yan beat him until he knelt and begged for mercy. “Twenty million, and I'll make sure you walk out of here in one piece.” People mocked her for being poor. “Lick the toilet and we'll give you a million.” Jiang Yan had no qualms about teaching them a lesson. “If you're that rich, why not donate three million each?” The whole internet mocked Jiang Yan for being unimaginably poor. The whole internet wondered who the angel among us was, donating tens of millions to dozens of families. One day, the angel among us livestreamed, and the whole internet was stunned. It was Jiang Yan, the very woman who had casually donated tens of millions. At first, everyone disliked her. Later, she became someone no villain dared to mess with. Her husband, who had been in a vegetative state, woke up. When people bullied him and he didn't say a word, she couldn't stand it anymore. “One million, and I'll help you get even.” When people hunted him down, she stood in front of him. “Three million, and I'll keep you safe.” But one day, she unmasked the mysterious figure hailed across the internet as the embodiment of justice for repeatedly fighting crime. To her shock, it was the very husband who kept insisting he couldn't manage without her protection.
