Review Detail of heff in I Have Awakened The Deduction System

I haven't read the other novel the other reviewers said it copied from but I did enjoy the first 2 reincarnations but around 3rd reincarnation, the author just decided oh, I'm bored with the MC, let me tell you the story of another character in length, like a bunch of chapters and I'll mention the MC once in a while so you know it's still the same novel. I know this new character that I'm going to spend a lot of chapters with is going to be relevant in this 3rd reincarnation only, but I'm bored with the MC and I wanted a new story. As a reader, I don't want that, so I didn't read those parts like around 50 chapters of skipped useless content.
