Wo Hua Kai Hou Bai Hua Sha

In her previous life, she was a palace insider, the consort of the fifth prince, famed for her haughty beauty. But overnight, her whole family was slain by order of the Emperor. As she died with hate in her heart, she was reincarnated as the daughter of the Shen clan, the ruler of the northwestern territory. Now she will use her cheat-like knowledge and looks to scheme and charm her way to the top! She is noble, beautiful, and cold, as she looked down on all before her. Nothing and no one will touch her heart in this life. (Source: Tencent, translated)
