If you are looking for a writing Masterpiece then you won't find it here. Some people call it a masterpiece and other stuff but down to its core Solo Leveling is just a regular weak to OP story. That being said one of the things that make people say things like it's a "masterpiece" or "it's the best of all time" is its art, the artist did a phenomenal job because it was FUCKING AMAZING. Even though down to its core it's just a simple zero to hero story it does have its little twist like (spoiler warning) how instead of it taking place in some other ancient magical world like most isekei, it actually takes place in modern earth where dungeons and hunters have begun to appear and the main character being one of them. The story might not be complex but it's still really enjoyable because of the art, the fights, and the main character is kind of a badass. I've read the web novel and in my opinion, I think that the Manhwa is an upgrade from it. I really enjoyed both especially the Manhwa and when I began reading I was so interested and hooked on it that I read 100 chapters in a day and even now that I've caught up with it I always look forward to the next week for the new chapter. I record you give it a try if you haven't and at least read the first 15 chapters as it kinda starts slow.
