Can you recommend a novel in which the female protagonist transmigrated to an alternate era and became the emperor's younger brother?

He recommended the novel,"A Time Traveler as Beautiful as Jade." This was an ancient romance novel. The female protagonist traveled to an alternate ancient time. In order to find clues about her family, she became the top scorer and sneaked into the imperial court. She planned to disguise herself as a man. She didn't expect that she would be named the number one male beauty in Lingjiang. In this era where men were superior to women, her identity was exposed and Mo Chenyuan, the Duke of Lingjiang, discovered her. He began to pursue his wife. The main plot was that the female lead stirred up a shocking wave in the court, caught villains, exposed crafty sycophants, and rose to the top. She was promoted to the position of Empress and became the first female scholar in history. She picked up flowers and smiled in the wild dance of snakes. She stirred up a pool of spring water, spring flowers and autumn moon, and the wind and clouds. I hope you like this novel. Muah ~
