There were a few points to note when writing a book on urban cultivation: 1. Setting the background and worldview of the story: urban cultivation is a relatively broad theme. You can use this as a basis to determine the background and worldview of the story. For example, you can set up a mysterious cultivation sect in the city or tell a story about a city dweller who accidentally obtained the ability to cultivate. 2. Set up the protagonist and villain: The protagonist is the core of the story and needs to have a distinct characteristic such as intelligence, courage, ambition, and so on. At the same time, he needed to set up a villain to add conflict and tension to the story. 3. Setting up the cultivation system: The books on urban cultivation generally involved the setting of the cultivation system, such as the cultivation realm, skills, spells, and so on. You need to clearly set each realm and skill and set a unique spell or skill for each character. 4. Setting the plot and rhythm: The plot and rhythm are the soul of the story. You need to design some fascinating plots such as the protagonist encountering a crisis, breaking through the bottleneck, obtaining powerful strength, etc. At the same time, you need to control the rhythm of the plot so that the story does not drag or rush too much. 5. Setting up the character image: The character image is an important part of the story. It is necessary to create a distinct personality and character image for the protagonist and villain so that the reader can better understand and like them. I hope the above points are helpful.
