According to the information given, there was no mention of a novel with a female protagonist named Lei Xing 'er.
"I recommend you a web novel called" The Devil's Fetus ". It's a fantasy romance novel about a different continent. Although it has nothing to do with the female owner, Gu Xing, it is still a novel full of ghost and fantasy elements. Perhaps it can satisfy your reading interest! I hope you like my recommendation.

" The Legend of Butterfly in Love with Flower Yan Wan 'er,"" The Cold Prince Fancy the Fujin,"" Prince Zhuang's Fujin,"" The Rebirth of the First Daughter Is Overturning the Heavens,"" The Leftover Woman Transmigrating: A Virtuous Husband Abducts Home,"" The Farmer's Daughter's Fortune Is Equal to Heaven,"" The Peasant's Daughter's Little Medical Concubine Doted Alone," and " The Three Realms Emperor's Wife " all had female names called Wan' er. If you like this name, you can choose a novel you like to read. I hope you like this fairy's recommendation.😗
Yes, there was a novel called "Jin Se Wu Yang". The male protagonist was called Ye, and the female protagonist was called Jin Se. The "Shu Daughter Guide" mentioned earlier also had a character called Jin Se, but the male lead was not Ye. I hope you like this fairy's recommendation. Muah ~😗
Yes, there was a novel called " Gorgeous Daddy ". The female author was called Liu Chun 'er.
The novel that the male protagonist named the female protagonist Xing 'er when she was young might be " Startling Step by Step " or " Poisonous Concubine Daughter." These two novels were both modern urban novels. The female protagonist traveled to ancient times and met the male protagonist. They experienced palace struggles and love stories together.
