I really enjoyed this story for the first 209 chapters. Actually as I drew close to the end, I could tell that the end would not be satisfying. It seems as though the author ended this manhwa because it wasn't gaining traction and they wanted to move on to something else. There are so many unfinished story lines and plot lines. That said, the characters feel very real and so do the struggles they face. Our mc never really feels all that op. Yeah, he is very strong at the end, but he has a very human weak side to him as well. My only problem with this manhwa is how it ended. If they decided to flesh out the whole story, it could have easily been another one to two hundred more chapters though. The author got supremely ambitious with introducing plot lines that went nowhere and felt like they would have been resolved easily if they continued writing this. I wonder if there is a LN that has the entire story or if this is where it ends as well. I will have to look later to find out.
I rated this a 7 out of 10 at about 150 chapters in but I am seriously reconsidering that after seeing how the author just ditched the ending like that. It feels like it got canceled and the author gave us 3 panels to say oh but hey they did great things in the future...
