I was surprised that people were rating this series pretty low. I think its a really good series, and it easily became my #1 favorite series to read out of all the manga, manhwa, and manhua I have read so far.
Even I read this manga as a solo leveling light novel first on kisslightnovels..and I mean everyone has different tastes in genres and art styles. The chapters have been getting better and better since chapter 1. I don't like how some other reviewers are telling people to skip chapters which prevents the readers from seeing the progress the main character makes.
The series would be rated lower probably if the main character was super strong from the get go without any growth being shown.
