Reborn, I Sent My Scheming Mistress to the Cold Palace

In my previous life, my mistress transmigrated into the palace with a modern mindset and disdained palace intrigue. When the kitchens sent us spoiled food, I fought and made a scene on her behalf. She got fresh food, then called me noisy. In the end, she openly promised to find me a good husband, but secretly, in her hypocrisy, married me off to a eunuch as his companion, all to clear her own path to power. After I died horribly, we were both reborn. She thought she could rise to the throne as empress just as easily as she had in her previous life. This time, I won't let her get her way.
