Post works on the official website of Cthulhu Mythology or other related literary platforms such as Cthulhu Mythology Bar, Cthulhu Mythology Forum, etc. 2. Submit to a local literary publishing house. You can find relevant publishing information in your local library or bookstore. 3. Online writing platforms such as Qidian Chinese Network. 4. Create your own e-book or slideshows and post them on an online writing platform. When submitting the novel, one had to submit the complete work, including the original text, outline, character setting, and so on.
