As someone who loves reading novels, I don't have any practical experience in finding novels. However, according to my knowledge of online literature, a novel that traveled from the Southern Song Dynasty to the present day might involve different topics and styles such as history, science fiction, fantasy, and so on. You can try searching some well-known online literature websites such as Qidian Chinese Network, Xiaoxiang Academy, etc. to see if there are any relevant novels recommended. At the same time, he could also pay attention to some well-known online novels to understand their genre and style so that he could better find novels that matched his preferences.
