A hidden dungeon that only I can enter

A legendary place that hides a large number of rare monsters and rare treasures - the hidden dungeon. Noel, the third son of an unemployed poor nobleman, was lucky enough to open the entrance to the hidden maze. In the Hidden Maze, Noel learned the ability to create, empower, and edit skills. In addition, when using this skill, you actually need to "eat delicious food" or "have close contact with a good-looking member of the opposite sex" in order to store the necessary points...? "A hidden maze that only I can enter, a low-key training to become the strongest in the world!"
