There were a few reasons for the slow update speed of Battle Through the Heavens: 1. Complex plot: The plot in the novel is more complicated and requires the author to spend more time and energy to conceive and create. This might cause the novel to update slower and require more time to perfect the storyline. 2. The issue of copyright: A novel is a literary work, and its copyright is usually owned by the author or the author. If the novel updates quickly, the author or the author may be more willing to keep publishing the same or similar works to maintain their copyright value. Therefore, the slower update speed might help protect the author's copyright and make it easier for readers to wait for the novel to be updated. 3. Reader's needs: The speed at which the novel updates also depends on the needs of the readers. If readers expect faster updates, authors might be more inclined to speed up updates to meet the needs of readers. However, if the update speed was too slow, it might cause readers to lose interest and negatively affect the quality of the novel. There could be many reasons for the slow update speed of Battle Through the Heavens, including the complexity of the story, copyright issues, and the needs of readers.
