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

After Althea returned to the dungeon, she immediately asked Lilith to guide her to where the elves stayed. Of course, Lilith had no problems with that and quickly went out to guide her. Ein, who was left inside the dungeon master's room, was stuck staring at the spot that Althea popped out of.

"... How did she teleport directly inside the dungeon master's room?" Ein genuinely couldn't understand.

After all, the dungeon master's room was supposed to be a separate space, with only the teleportation arrays anchoring it to the real world. Teleporting directly into it is like trying to jump from one fast-moving car into a slow-moving one... While blindfolded. If you miss the exact timing, then you'll fall on the asphalt and get badly hurt.

In the end, without getting an answer, Ein just tried to forget about it by watching the dragonkins wipe out army after army while slowly making their way to the capital of each kingdom.
