This manhwa is the prime example of unoriginal. which most times in manhwa isn't a bad thing. Like Solo Leveling, it isn't original but it just executes the premises better. All this manhwa has going for it is its art. I had to force myself through boredom to continue reading. The characters are very typical as well, the story becomes extremely predictable adn you never even fear for the mc because you know he's just going to beat it. If he enters a dungeon that's supposed to be (lets say "F" class) you already know something is gonna go wrong, and that it isn't a normaldungeon. The mc barely has any personality and just feels empty, not in a depressed/sad way.
If you are looking for a manhwa with every basic manwha premis combined into one, read this. Otherwise i would never recommend this.
