SeraphWedd

In the year 2025, for unknown reasons, dungeons started appearing all around the world. Monsters started invading nearby cities and massacring the citizens. The world population was dropping by the millions each day. To fight against the monsters, the whole world decided unanimously to create genetically modified human beings called "Warriors" by injecting a serum they called "Elixir". Thus, started the counterattack of the human race.

On a certain day 12 years after the start of dungeon appearance, while raiding the last and hardest dungeon in the world, an event occurred. After getting betrayed by his teammates, Warrior Ein was pushed down a bottomless pit just before facing the last boss as a sacrifice. Regret filling his heart, he cursed at his former teammates, swearing to take revenge against them before losing consciousness.

However, when he opened his eyes, he found himself as a dungeon master in a new world. Since he will die if the dungeon gets conquered, he decided to protect his dungeon from invaders while searching for a way to return to Earth. Will he be able to return to Earth and enact his revenge?

I am a Problematic Dungeon Master

Ein had been keeping watch on the army's movements inside the dungeon master's room for the last two days. Some of them had been inside the firing range of the cannons already, but their formation was elongated, meaning less than 40% of them entered the range after 2 days.

They were stealthily spreading their army around the forest surrounding the dungeon, probably planning to encircle them to not let anyone escape. Unfortunately for the Geoburg Kingdom's army, their surprise attack was already discovered ages ago.

They stayed roughly five kilometers away from the outermost wall, which should be enough distance to keep them hidden from the wall's observers. However, the dungeon's eyes spread farther than they could imagine.
