One of the best type of leveling up manghwa Ive EVER read. Jin woo is such a strong and smart character. One of the best examples of going from the weakest character to the strongest in the world. Going from E Rank to over National to Monarch level, he is easily the strongest in the Manghwa. I also really liked it since there was not an overly huge concentration on romance which really lessens the appeal in stories like these. Although in this case I kinda wanted to know more about Hae In and Jin woo and their relationship or whether they got together. But it was a very good story and I highly recommend!!!
