In many novels, there are often some seemingly unrelated things that have a huge causality between them. Here are some examples: Fate and fate: In many novels, the protagonist can often change his fate and fate through his own continuous efforts and choices. These changes are often determined by what he has experienced before. 2. Cause and effect cycle: In some novels, there are often characters who commit crimes for some reason and cause themselves to be in trouble. And these predicaments further triggered more karma cycles, making it even more difficult for him to escape the manipulation of fate. 3. Accident and coincidence: In some novels, the protagonist often encounters some seemingly unrelated accidents and coincidences. These accidents and coincidences are often determined by things that have been decided before. 4. Magic and technology: In many novels, magic and technology are often interconnected. Together, they form a complex magic technology system. The protagonist would often use magic and technology to achieve something that seemed impossible. Family and friendship: In many novels, the protagonist often finds that his family and friendship can bring him great help and support, and even become the source of strength to overcome difficulties. These seemingly unrelated things often played a very important role in the novel, and the relationship between them was often full of causality.
