Review Detail of troutrun in Reincarnated With The Strongest System

This is a well written story. I originally skipped this story when it was first released because of the MC enslavement reviews but was bored and forgot about the reviews. I really enjoyed the story up to the part where the MC got enslaved by his dark magic teacher. Thought I could get pass it, but I just loss interest after that part. Rated this at 3.8.
