Ten years ago, the gates of our world opened with a world of monsters. After that, some mortals were given the gift of destroying monsters inside the gate. Such mortals were called hunters. However, not all hunters are strong enough. Sung Jin-Woo is a level E hunter.
The guy has to risk his life in the dark dungeons, performing the most unpromising tasks.
The fact is that the hunter does not have the necessary qualities to increase. So he has to perform rough work. Sung Jin-Woo went down into the dungeons again and again, fighting with the lowest monsters until one day he wanders into the dungeon level D.
Staying in the most difficult dungeon gave the guy an amazing ability “System”, which contains a lot of secrets about raising the level. In order to gain “career growth”, the hunter will have to train regularly, based on the list of tasks. Perhaps such a turn of events will lead the newcomer to the rank of S, the highest title of hunter.
