I'm not sure specifically as I haven't read it in detail. But generally, it might be about the adventures or the life of an amphibian man, perhaps his struggles in two different worlds - the land and the water.
One common theme is acceptance. Since different amphibian species often have different appearances and behaviors, the stories usually involve characters accepting each other despite these differences. For example, a small, brightly colored frog might fall in love with a large, dull - colored toad. And they have to accept each other's looks.
The main character in <<The Immortal of the Other World>> had his dantian broken and became a cripple because of a woman. He was later saved by the Immortal of Qingxuan. I can recommend this book to you. I hope you will like my recommendation. Muah ~😗😋
Captive breeding is a key element. For instance, in the case of many endangered amphibians, breeding them in captivity ensures their numbers don't decline further. It allows for the production of offspring that can later be released into the wild.
One popular amphibian love fanfiction could be 'The Frog Prince's True Love'. It tells a story of a frog who falls in love with a kind-hearted maiden in a magical forest setting. The story is filled with sweet interactions between the two characters.
Another place could be some dedicated movie or genre - specific fanfiction forums. These forums might have sections for stories about unique pairings like Elisa and the Amphibian Man. You might need to register and search through their story archives.
The unusual relationship between them. It's a cross - species relationship that defies the norm, which makes for very interesting character dynamics in fanfiction.
