The Heiress Luo Wanwan

Luo Wanwan and Li Yichen are husband and wife, and they have never met. Her father is the Minister of Rites, and she says whatever comes into her head and styles herself a swordswoman of the jianghu. He holds a deputy minister's post at the Dali Temple, where criminal cases are judged. She runs off to escape the marriage and on the road gets caught up in a murder case, and that is how the two of them meet, trading blows with no idea who the other is. They come away from it treating each other as enemies. She wants the truth of the case, so she dresses as a man, gets herself into the Dali Temple, and becomes his assistant. From there they work cases together, clearing old unsolved ones and going after wrongdoers, and somewhere in the middle of it a romance starts up between them, with him still unaware that his assistant is the wife he never met.
