My Scumbag Father Dotes on His Mistress, So I Was Reborn to Take Back My Dowry and Get Revenge!

【Revenge after rebirth + interworld exchange System + exile + punishing scumbags + everyone dotes on the heroine】 In her previous life, Gu Tingxue's father, Gu Tinglan, wanted to bring his mistress into the family. He framed her maternal grandfather's family with forged letters, getting them exiled to the far north. After her grandfather fell from power, her mother was demoted from wife to concubine, and she became a daughter of secondary status, left to be bullied by anyone. Her eldest brother, Gu Qinghe, had been gifted and brilliant, but someone drugged him, leaving him mentally impaired. Her second brother, Gu Yanzhao, was a skilled martial artist. During the military examination, his horse panicked while he was too weak to control it. He was thrown from its back, and both his legs were crippled. From then on, the four of them were confined to a dilapidated courtyard in the estate. In the twelfth lunar month, snow fell thickly and the bitter winter dragged on, yet they didn't even have a warm quilt and could only huddle together, shivering. There wasn't even leftover food to eat. Every day, they were given only pig slop. As Gu Tingxue, her mother, and her brothers froze and starved to death in the cold rear courtyard, her soul watched in furious disbelief as Gu Tinglan and his mistress, Lin Wanniang, spent her mother's dowry, admired fireworks filling the sky, feasted on delicacies, and dressed in fox fur and fine brocade. Then Gu Tingxue was reborn and accidentally activated the interworld exchange System. In this life, she would help her mother and brothers live well, and make sure every wrong was repaid in kind!
