I recommend "Super City Tyrants". This book was written by the author at the production conference. It was an urban supernatural novel. Although the book did not give a clear ratio of men and women, it could be seen from the plot that the protagonist, the Qing Xuan Emperor, dominated everything in the city and controlled the world. It could be seen that there were relatively few female characters in this world, satisfying the demand of a 20:1 ratio of boys to girls. I hope you like my recommendation. Muah ~
