The Unending Dungeon

* Anime
* Manga

The **Unending Dungeon** or **Infinite Labyrinth** is the a location of the **Ore dake Irerukakushi Dungeon.**

It's a Hidden Dungeon where Noir learned of it's existence with his Great Sage skill. The remarks of the four layers of Ghosts suggest that 200-300 years ago. It is Olivia, not Noir, who first went inside after it was sealed.

It is located inside a cave located 15,000 meters southwest of the Royal Capital, in the mountains.

In addition to locating the entrance, one needs to push the rotating wall on the left to reveal the stairs to a massive iron gate. No matter what kind of magic attack one summoned, it didn't seem like it'd budge in the least. It is also necessary to recite the required spell: "「The Hidden Dungeon only I can enter. Secretly becoming world strongest!」".

The Floors of the Dungeon are full of rare monsters and creatures, as Noir noticed after he saw its slime's, because the golden ones were practically unheard of.

The Floors of the Unending Dungeon can simulate different environments, as the 7th and 17th Floor have fake suns, and the 9th and 11th Floors were similar to an ocean and a volcano.

The Unending Dungeon can be very dangerous, because even its "*bonus level*", the Forest of Gold, is full of dangerous creatures. As Noir progressed through the Floors, he noticed the monsters were getting stronger.

Besides monsters and creatures, the Dungeon is full of illusions and traps, as the Death Chains that sealed Olivia, and supposed humans like Huck, Uuck and Auck in the 8th Floor, the audience in the theater inside the Path of Laughter, Son and his battalion in the Path of Anger, the audience and host of the fighting arena in the 13th Floor, Olivia Clone in the 15th Floor and the Four Siren Sisters in the 16th Floor.

In order to go through some floor, the seeker must complete some trials, like strengthening a weapon in the 12th to open the pathway to the 13th Floor, defeat three adversaries in the fighting arena in the 13th Floor to open the gate to the 14th Floor and the 14th Floor Trials. These tasks can be a trap, like strengthening a weapon that will be used by an adversary against it's former user in the next level.
