After Wang Baochuan died, he turned into a ghost and wandered for thousands of years, witnessing the rise and fall of history and acquiring countless skills and wisdom. Once she was reborn and returned to the turning point of her destiny, she vowed to make the betrayer Xue Pinggui pay for her debt with blood. In her previous life, she worked hard in a cold kiln for eighteen years in exchange for the position of Queen of the Eighteenth Heaven. In this life, she wants Xue Pinggui to experience the eternal disaster after the dream of the Emperor of the Eighteenth Heaven. After rebirth, Wang Baochuan is no longer the naive daughter of the Prime Minister, but the "Black Lotus" with deep scheming and decisive killing. She first helped her eldest sister Jin Chuan and her eldest brother-in-law Su Long to be happy; she gave her second sister Yin Chuan glory and wealth to her arrogant second sister Yin Chuan; she remarried her second brother-in-law Wei Hu and helped him become the prime minister, showing her love and affection. At the same time, she helped Wei Bao's sister Wei Guifei give birth to a prince, paving the way for the future. Facing Princess Xiliang's battle, she wanted her to see Xue Pinggui's true face. With the help of her second brother-in-law Wei Hu's military talent, she planned to attack Xiliang, expand the territory, and unify the country. On this road of revenge, her eldest brother-in-law Su Long's resourcefulness, her second brother-in-law Wei Hu's military skills, and her husband Wei Bao's love and support became her most powerful backing. Wang Baochuan vowed that in this life she would firmly control power, status, fame and money, make all those who betrayed and bully her pay the price, and at the same time protect those who truly love her. However, there are many conspiracies in the court, and Xue Pinggui joins forces with Xiliang forces to set up traps everywhere. Wang Baochuan must subvert this patriarchal society as a woman within a limited time, rewrite history, and complete the seemingly impossible cause of revenge and reunification.
