As a fan of online literature, I don't have the ability to actually write, but I can provide you with some possible reasons: 1. Lacking inspiration: Writing requires inspiration and creativity. If you lack these elements recently, it may be difficult to create an interesting novel about pure DNA demons and devils. 2. Time and energy: Writing requires a lot of time and energy. If you don't have enough time or energy to invest, it may be difficult to create excellent works. 3. Unpopular subject matter: If the chosen subject matter is not popular, it will be difficult to create a popular novel even with rich imagination and inspiration. 4. No new ideas: If you feel a lack of inspiration and creativity, you may need to spend time thinking about new subjects or ideas to stimulate your creative enthusiasm. In short, creating a good novel required a combination of many factors, including inspiration, time and energy, subject matter, and ideas.
