I recommend a novel called "The Fickle Mercenary Concubine: A Prince's Wife Must Not Be Bullied". It has both ancient plot and transmigration elements. The female protagonist, Miss Jiu, is fickle and unruly, while the male protagonist, the Red Flame King, is domineering and arrogant. The two of them compete with each other in wits and courage. The plot is compact and interesting. Also, this book is free. I hope you like this fairy's recommendation. Muah ~๐
