The Reborn Poisonous Concubine Is Too Frivolous

In her previous life, she was Concubine Gu who died in tears. After being reborn, she suddenly changed into the wife of a marquis. Her husband did not favor her, her family did not care for her, her concubines oppressed her, and her servants treated her badly. She sees every move and moves forward step by step, stepping on mountains of corpses and seas of blood, to overthrow the world and wash away all her grievances! But when did a fox tail appear on the road to revenge? "Your Majesty, do you want someone who has been abandoned?" "Yes, I will allow you to be betrothed and prosperous as a gift."
