Review Detail of Roinuji in Sword God in a World of Magic

This is one of those famous cases where the person possesses a genuinely great idea but executes it poorly. About 90% of the story consists of the protagonist's training, which is incredibly tedious. The protagonist is portrayed as an emotionless rock, and towards the end, undergoes an abrupt personality shift to become a clichéd villain "devoid of empathy." I'm a fan of stories featuring villains; my favorite novel is Reverend Insanity, but Shang is perhaps the most uninteresting character I've ever come across. The world depicted in the story feels entirely artificial and lifeless, almost as if it were merely a theatrical backdrop. The characters don't hold much significance to the narrative and seem to exist solely to create a false illusion of a living, breathing world. Occasionally, a character plays a crucial role in advancing the plot, but once that purpose is served, the author either forgets about them or kills them abruptly. To be honest, some parts of the story piqued my interest, such as the action-packed fights and the intricate power system. However, I prefer stories that evoke strong emotions, that quicken my heartbeat, and keep me on edge, eagerly anticipating what will unfold in the next chapter—a roller coaster of emotions, so to speak. Yet, this story felt more like a monotonous car trip on a bumpy road. I had hoped for something captivating, but it turned out to be disappointingly mediocre.
