A Proper Lady Who Knows Martial Arts

Looking for an Ancient-Era Romance with a Female Lead Who Seems Like a Proper Lady but Is Secretly Formidable

Is It Possible That Gong Douwen Appears to Be Abusing the Female Protagonist, but Actually the Female Protagonist Is Foreshadowing the Abuse of the Male Protagonist?

I want to read a book like "After entering the palace for her sister, the imperial concubine seduces the emperor to ascend to the throne". I just want to watch the heroine plan step by step to make the hero fall. In the middle, she can choose the white moonlight cinnabar mole and then brutally abuse the durian tip of the hero.
