Please recommend a novel. The male protagonist shuttles between modern and ancient times. He brings modern items such as lighters to ancient times for trading.

I recommend the book "Space Doctor: Traveling Through Ancient and Modern Times as a Purchasing Agent". It tells the story of the female protagonist committing suicide in the modern world because her boyfriend cheated on her. She traveled to ancient times and obtained space. She could also bring some modern things back to ancient times to sell, instantly becoming a rich woman. The male lead was a prince with facial paralysis, while the female lead was a nurse with full marks for her skills. The plot of this novel was very interesting. At the same time, it described the differences between modern and ancient times. The interaction between the male and female leads was also very interesting. If you like modern and ancient novels, this book is definitely a good choice. I hope you like this fairy's recommendation. Muah ~😗
