My In-Laws Drained Me Dry. Reborn as Empress, I’ll Kill Them All

Cangwu Qing met a horrific end in her previous life. After marrying into the Earl's household, she kept the crumbling family afloat with her dowry. Over eighteen years of marriage, she bore children for the heir, Nan Xun, and even raised the child his maternal aunt brought with her as if he were her own. She also turned his cousin, born to a merchant family, into a fine young lady fit for the capital's noble houses. In the end, her own son won distinction on the battlefield and was granted a princely title. Her adopted son became a powerful minister of his age, and her cousin entered the palace and became an Imperial Noble Consort. The Earl's household, nourished by her blood and flesh, flourished overnight, its splendor blazing like flowers in full bloom and a fire fed with oil. But her hands and feet were cut off, and she was reduced to a prisoner. Her father was banished to a bitterly cold land. She begged the people of the Earl's household, whom she had once nourished with her very flesh and blood, to save him. Her cousin, once so meek before her, replied, “Cousin, you raised my child. Your husband is mine, too. What has happened to you is exactly what I've always wanted to see. It won't help to beg anyone.” She gave everything in this life, only to end with her family destroyed and her loved ones dead. Reborn, she sees them all for what they are: a prince made king, a powerful minister, a beloved consort? Let them all die! Wait, why is the ex-husband who looked down on her in her previous life now kneeling three times and bowing nine times before Buddha, begging her to come back? Why are the people of the Earl's household, who treated her like a pawn, clinging to her legs and refusing to let go? And why is the capital's infamous tyrant, who always scowled whenever he saw her, following her everywhere? He says he's been thinking about her for years? But where were you before I got married? Wait, you say if I marry you and become empress, I can take revenge with my own hands, bring glory to my family, and help all under heaven? And if I want, you can even support me in becoming empress regnant? Empress or empress regnant? This is so hard to choose.
