Excellent mawha, it has become my favorite. The fights are getting cooler with each arc and the design is very good. In addition, the story is very interesting and the "dungeons" of this work are very different from other Korean manga. But the best of all the work is the protagonist. He is not overpower, but he uses his intelligence to be stronger than the others, this is very cool. And besides, he is a very well built character, MC is a good person, but if the situation calls for someone tougher and more manipulative, he takes on that role without any problems. I recommend give a chance,my favorite manwha.
