Forcing me to raise a concubine? The mistress of the Marquisate has gone mad

Lu Hua was reborn. She was murdered by the emperor's adopted son and his biological mother, and was killed before she died! She would not be at peace as a ghost if she didn't take revenge. As a result, when she opened her eyes, she turned into the mistress of the marquis's house, Shen Ruoyan. She was still a cowardly mistress whose husband favored his concubine over his wife and even wanted to raise the son of his concubine with her! She was the dignified queen mother and the champion of the last palace fight. How could she not handle this mere marquis's house? Let her raise a son of the concubine? Sure, she did! When she was the queen, she liked to help others raise sons the most! One raises a whole nest! Let the concubine come in? Sure, let her come in! While the concubine was waiting to be married, she directly gave the marquis two concubines! Where can I find her in this world...
