To write a novel, one needed to first determine the basic framework and theme of the story, and then gradually develop the plot and characters. If you want to introduce supernatural elements in the beginning of the novel, you can consider starting with strange events or supernatural phenomena in daily life, such as stories that happen to people around you or friends, and then gradually guide the reader into the supernatural world. In the second half of the novel, fantasy elements could be added, such as exploring the mysterious world, cultivating spells, fighting evil forces, and so on. These plots could be developed by increasing the character's abilities and adventures, or by building a complex worldview and setting to attract the reader's interest. In the process of writing, one needed to pay attention to maintaining the logic and cohesiveness of the story to avoid contradictions and incongruities. At the same time, he also needed to constantly revise and polish the work to make the plot more vivid and the characters more vivid.
