I'm not sure which specific 'emperor of the sea' story you are referring to. There could be various fictional or historical interpretations. It might be a story from a particular mythology or a creative work. Without more context, it's difficult to tell the full story.
If we consider Poseidon as the 'emperor of the sea' in Greek mythology, his significance is huge. He was a major deity, and the sea was a vital part of the ancient Greek world, both for trade and for fishing. His wrath could mean disaster for sailors, so they often made sacrifices to him.
I don't know where the explosive point of the Blood Sea Demon Emperor is.

No, it is not appropriate. Writing smut (pornographic) fanfics involving such unusual and inappropriate pairings is not acceptable in a general moral and ethical context. It also goes against the values of a healthy and positive creative community.
One idea could be exploring the unique relationship between the Sea Emperor and the main character in a more light - hearted, 'lemony' way. Maybe the Sea Emperor shows a different side of itself, like having a sense of humor. Another could be a story where the Sea Emperor uses its powers in unexpected ways to help the character, all while there are some comical or sweet 'lemon' - like moments. For example, it could create a beautiful underwater scene just for the character as a friendly gesture.
One negative impact is that it can be very offensive to a large number of readers. People may be put off by the inappropriate sexual nature of the content. Another is that it can give a bad name to the fanfic community as a whole, making it seem like a place full of vulgarity.
One way to make your Subnautica Sea Emperor lemon fanfiction unique is by changing the power dynamics. Instead of the character always being in awe of the Sea Emperor, have the Sea Emperor be a bit more vulnerable in some situations. For the 'lemon' aspect, introduce a new species that is only attracted to the 'lemon' - like qualities of the Sea Emperor. This new species could cause some chaos or be a source of new friendships. You could also write the story from the perspective of a small sea creature that witnesses the relationship between the Sea Emperor and the character, adding a fresh and different view.
The story of the Eight Immortals Crossing the Sea came from the ancient Chinese novel Strange Stories from a Chinese Studio. In the story of the Eight Immortals Crossing the Sea in the novel, there was no royal relative who had not become an immortal. Although some immortals were Taoist immortals, most of them were Buddhist figures such as Zhang Guolao and Tie Guaili. In the story of the Eight Immortals Crossing the Sea, the immortals performed their own magical powers to complete the task together.
Sorry, without more information, it's impossible to determine the author of this 'the sea the sea novel'. There are so many novels out there with different levels of popularity, and this one could be by a new writer or from a small press.
