After Time Travel, I Became the Arrogant Prince's Scheming Concubine

[Time travel + double life + deep sadomasochistic love + domineering and arrogant male first + beautiful, strong, miserable and dark male second] Li Siyuan traveled through time and became Du Ruren, the most dignified prince in the Great Zhou Dynasty and the unpopular one. She is committed to having money and leisure, and she does not want to compete with the women at home for the "hot potato". Unexpectedly, she, Du Ruren, is actually a fake, and even the identity of the eldest lady of the Du family is fake! After she escaped from the Prince's Mansion, she devoted herself to becoming a wealthy businessman, but she was forcibly abducted! This time, she regained her memory and realized that she had actually been reborn! In her last life, she died tragically in battle, and was told before her death that her sweetheart was her brother! And in this life, she will never let tragedy happen again, she will help him ascend to the top of power! Just when she thought everything was settled, the truth emerged! At the top, she is powerful and independent... (Notes for reading the article: 1. Fake brother and sister! The heroine and the second male lead are not biological brothers and sisters! 2. The first male is a pure ancient, and the female protagonist is not the only one in the early stage. 3. The temperament and style of the female protagonist in this article changes with experience. 4. It is not a story about a fight in the back house! The title is only an identity of the heroine in the early stage, and it cannot summarize the full text at all. 5. The early stage focuses on daily life + the middle stage has a bit of intrigue + the later identity truth. 6. The first male and the second male are determined based on the order of appearance, and have nothing to do with the proportion of the content.)
