Bai Yun encountered a shipwreck on an uninhabited island and met a mermaid on the sea. Shang Que (the mermaid who saved Bai Yun) is the descendant of the Queen of the Mermaids and the God of the Sea. Mermaids are evolved creatures with certain non-human abilities. The lifespan of a mermaid is several decades longer than that of a human being. The age of an adult mermaid is thirty, which is equivalent to eighteen years of a human being. It is forbidden for mermaids to marry humans. The ancestors of mermaids have always left ancestral teachings that all mermaids who marry humans will inevitably have bad luck.
Concept: A fantasy-inspired novel that breaks reality.
