😋I recommend the following underworld novels to you: 1. " A Rebellious Lady at Home ": It was a love story between a rebellious lady from a wealthy family and the godfather of the Italian mafia. It was full of underworld atmosphere. 2. Stormy Storms: A traditional wuxia novel. It tells the story of the secret war and conspiracy between the officialdom and the underworld in the late Ming Dynasty. It is complicated and exciting. 3. " Paranoid: Mysterious Chief Tyrannical Love ": The young master of the underworld of a wealthy family dotes on the female protagonist. The two of them fight with wits and courage, and all kinds of schemes. It's very interesting. The above is my personal recommendation. I hope you like it.
