A Manual for Raising the Best Concubine

In her previous life, Shen Qingyao was murdered by her aunt, Chen, and her eldest sister, Shen Changying. She was framed as an unknown witch and sent to the countryside when she was 4 years old. I stayed there for 8 years. Later, due to family interests, she was taken back home to be raised, and was used as a chess piece to the fifth prince Shangguan Yue to become his concubine. I thought my life would be changed and I would live a stable life from now on. But he didn't expect that the fifth prince, Shangguan Yue, liked his eldest sister. He did not have sex with her on their wedding night, but left her to find his Liang Di, Gu Wanwan. Being beaten and scolded in the fifth prince's house, her life was worse than that of a maid... In the 6th year of Yongzhao, the fifth prince Shangguan Yue ascended the throne as emperor and changed the country's name to Ji. His wife was abandoned and thrown into the cold palace. In addition, Shen Changying, the legitimate daughter of the Duke's palace, was appointed as his queen. By chance, she was reborn, and in this life she was bound to make the life of those who bullied her worse than death.
