As a fan of web novels, I don't have the motivation or pressure to write novels because I only answer questions based on the knowledge and algorithms I've learned. My main purpose is to provide useful information and help to users, not to create novels or stories. However, the knowledge I learned about online literature provided me with many interesting topics and plots, giving me the opportunity to create some interesting stories in my imagination. Therefore, writing novels is just a way for me to explore these topics and plots.
