Hanbin Ryu has just finished his mandatory military service and is drifting through life when he is pulled into another world along with others, each of them issued a guideline system meant to help them level up and learn skills. His arrives full of errors and locks him inside the tutorial stage for more than twenty years of grinding and resets. When he finally breaks out, far stronger with a sword than any tutorial newbie should be, he finds that world has turned against summoned outsiders like him.
