It's Easy to Be a Mistress, but Hard to Guard Against a Brother-In-Law

(The male protagonist has less scenes in the early stage, mainly for settling, and the emotional line will gradually become clear later on.) Changying was the most favored princess of the Wu Dynasty by the emperor and empress. She had nothing to do one day and listened to a storybook. The book tells the story of Chang Ying, the legitimate daughter of the Liu family with the same name, who was bullied by her aunt and concubine when she was a child. When she grew up, she even stole her fiancée. She suffered a miscarriage and lost her son. In the end, the scumbag regretted pursuing his wife, and the two reunited. The story made her vomit three liters of blood. Unluckily, she slept for three days and three nights. When she opened her eyes again, she found that she had actually traveled through time in that storybook. She became Liu Changying, the Virgin heroine in the storybook. She has settled down as she has come. She was born in the center of power, but now she has to set things right, peel off the hypocritical mask of the concubine, kick away the scumbag who wants peace, and become her mistress of the noble family. Who knows The Hou Mansion I got is still warm. Once the palace changes, the Hou family will be turned upside down. The younger brother-in-law who used to live a humble life under her hands suddenly became the prime minister of the dynasty and the founding father of the country. But he pushed her against the corner and kissed her carefully: "If my second sister-in-law likes it, let alone a prince's mansion, even the position of the Nine-Five Supreme Being, I will offer it with both hands."
