This Manhwa is awesome. One of my top Manwha's I am reading.? It is fairly new, but it is really amazing. The main character goes from weak to strong. I like that kind of genre. Recommend to read this. I think according to Naver it is 9.4/10 So by looking that, can tell that it is awesome.
So I hope you share your own opinion on this Manhwa. Good luck reading it.
