I just read a novel in which both mc and ml are snakes, and I was very interested in looking for similar ones. I just ask they are not orcs or shapeshifters. They can only be animals (obviously with human intelligence). I have already read all the novels translated with mc or ml with animal form, so if you can recommend untranslated novels from jjwxc or other sources, I will be grateful. To summarize, a novel like A Nest of Snakes Inside an Old Tomb. Not necessarily snakes, it can be another animal. If the novel has mpreg, a thousand times better.
