I recommend a novel similar to "The King of the Underworld" called "The Queen's Town." It's also a modern romance and urban life novel. The story was about Wei Mingyue, the eldest daughter of the Thousand Jin family, who became the mayor of a town after her family fell. She regrouped and built a prosperous town. Similar to Underworld King, it was a story about how an ordinary person rose to power in a game of thrones. I hope you like this fairy's recommendation. Muah ~😗
