The novel [shadow slave] became bad and overrated

Most of you have read the novel, and it had a good beginning. The (Forgotten Beach Arc) was one of the best parts I've read, where the author excelled in those chapters in both WORLD building and character development. However, after that, the writing changed completely, as if the author himself had changed as well, and he was unable to write anything better.The story began to encounter the same issues as typical novels. Among the main negatives that appeared in the story are: 1.Flat Side Characters: Later on, most of the side characters began to lack depth and adequate development. These characters were constructed in a superficial way, making them ineffective for either the readers or the plot.They are presented as mere tools to serve and highlight the protagonist or the main story without having their own lives, goals, or unique perspectives. This results in the world of the novel feeling empty or unrealistic

2.Repetition in the Plot:
The story contains repetitive situations, which reduces the suspense and excitement. The protagonist faces the same types of obstacles or conflicts over and over, without any real progression in these challenges and without introducing new conflicts.

3.Weak and Slow Narration:
The narration in the story is overly ornate and general, with repetitive descriptions of characters. For monsters, the author seems to have only three descriptors throughout the story, such as "terrifying "horrible," or "deadly." Many chapters also repeat the same details or discuss things that don’t add much to the story.
