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

Michelle, Althea, and Nayta, along with Lilith, who came a little bit late, stared at Ein as if he were some sort of rare animal. The spell he used before, what he called [Vanish], was something that literally went against the laws of the universe. It "deleted" a Vestige's existence from the fabric of reality, killing it in one go!

"Master, you became a little too overpowered with that new spell you made."

Unable to hold her tongue any longer, Lilith muttered with furrowed brows.

Melina's spell, which made Ein and Althea jump back in time, only went against the laws of time and space, which state that time can only move forward and not back. However, this one that Ein made went against several laws simultaneously.

"Well, it is powerful and can one-hit beings like gods... but it comes with a pretty heavy price." Ein sighed, waving his hand and showing an astronomical value. "Can you see this number? I just used 0.1% of this to defeat that Vestige."
