I can recommend you a few fictional historical novels that are about the collective transmigration. They are all finished: 1. [Shu Men]: The story of a young man who traveled to the depths of the palace in history and slowly broke the rules of the palace world, eventually becoming a top-grade young king. 2. Later Tang: It described the growth of a rice worm official and how he survived in troubled times. 3. "Wife as the Viceroy": It tells the story of a man who transmigrated to become the husband of a female Viceroy and guarded the country for his wife. I hope you like my recommendation. Muah ~
