Transmigrated as the Vicious Eldest Sister-in-Law, I Make the Little Villain Drool with My Hauls from the Sea

Caught in an ocean current, Lin Shuxin opened her eyes again and found herself transmigrated into the villainous true heiress of a period novel she had read not long ago. The original owner had been switched at birth. Her parents doted on the fake heiress, while she was treated like a weed by the roadside. At long last, she escaped the countryside, only to become the fake heiress's shield and be sent back to the countryside before she could enjoy a good life. Her parents even sold her to an older man who had already been married once, so she could become his second wife and make life easier for the family. With no other choice, she latched onto a disabled man and married him... Transmigrated into the story, Lin Shuxin couldn't stop criticizing the original owner for being so clueless. She had listened to her scummy parents and sold off her powerful twin siblings, then squandered the winning hand she'd been dealt. Years later, the two siblings returned from northern Myanmar as villains in the book, and the first person they went after was her, their wicked sister-in-law! Lin Shuxin broke into a cold sweat as she looked at the two red-eyed little tykes, bound up and struggling. Luckily, she'd transmigrated into the book at just the right point. She flatly refused: “I'm not selling these kids!” With an empty house to her name, raising children was hard. Raising little brats who would grow up to become villains was even harder! Lin Shuxin sighed, then clenched her fist. At least she'd grown up by the sea, so gathering seafood at low tide was easy. Better still, she'd awakened a golden finger: an upgradable pocket-space System! Years later, Lin Shuxin held her university acceptance letter, her hand clasped in her husband's, while the children gazed up at her with shining eyes. She smiled softly: Who says a wicked sister-in-law can't turn over a new leaf?
