Writing Quality: The writing quality is good overall, as I can understand it, but there are still some mistakes. I would rate it 4 stars. ⭐⭐⭐⭐Story Development: I didn't enjoy the story development much, except for the moments when the main character (MC) used his brain towards the end. That part was good. I would rate the story development 3 stars. ⭐⭐⭐Characters: Unfortunately, I don't like the MC. I found him to be unintelligent, to the point where it frustrated me. It bothered me how easily he allowed others to see him as weak. Although there were some instances where he regained his strength, they were infrequent. Overall, the character development was not satisfactory, and I would rate it 2 stars. ⭐⭐World Background: The world background has some details, but it often lacks sufficient descriptions. For example, the author uses generic names like "ruin city" without providing enough specific details to fully imagine it. I would rate the world background 3 stars. ⭐⭐⭐Updating Stability: The updating stability is excellent, earning it a 5-star rating. ⭐⭐⭐⭐⭐Evaluation: The story has potential, but the MC's development is a major drawback. It took too long for him to start using his brain effectively, and expecting readers to wait for over 50 chapters for that moment is frustrating. I hope the author considers improving the MC's character earlier in the story.(Note to the author: Please consider this review as constructive feedback. It took me 10 minutes to write, and I hope you take it to heart.)
