Demon Lord's Reincarnation

Erste followed Gratz toward the center of the human headquarters. In the center of the incredible city built in a dimension hidden from even the Gods themselves was a gigantic fortress. It was a fortress made of unknown materials, just standing near it Erste could sense the immense mana being hidden within it. The fortress looked extremely gorgeous, it was a mix of fantasy and sci-fi elements with its middle-age aesthetics and its state-of-the-art defense system.

"So this is where your leader is staying, quite impressive." Erste praised as he looked up at the fortress.

"That's not entirely right, the leader is staying somewhere here, but not inside the fortress."

"Then where is your leader hiding?"

"Erste I might have some respect for you, but I cannot allow you to disrespect the leader like that. Don't speak as if the leader is some sort of coward."

Seeing the anger on Gratz's face, Erste shrugged his shoulders.

"My bad, I didn't mean to offend you."

"... Fine... As for the answer to your question, the leader isn't in the fortress but underneath it."

Gratz and Erste stood in front of the entrance of the fortress but they did not enter instead, Gratz tapped on the ground while sending tiny bits of mana in a rhythmic way. After a few taps the ground where Erste and Gratz stood suddenly shook and they started descending.

The speed of their descent was rather fast and would frighten normal humans, but as the two of them were anything but normal the speed of their descent did not affect them in the slightest.

Based on the speed at which they were descending and the time it was taking they were already deep underground. While they were descending silently Gratz suddenly spoke.

"This is not known by many but the leader has faced an Old God, even though the leader was unable to kill the Old God like you did but the leader was able to fight until the two agreed it was a draw."

"Is that so..."

Erste was only listening halfheartedly as he had sensed something amazing the more they descended. After the battle with the Old God and with his training, Erste was able to sense the flow of outside mana better, though he was still unable to feel the chaos energy. Now he was sensing an incredible amount of mana flowing through this place, he was sure that most of the mana in this dimension was going through this place.

"I see that you have understood why the leader is staying here." Gratz who noticed the changing expression on Erste's face spoke with a smile.

"Is that so."

...

It took a few minutes for the elevator to stop. When they got off the elevator the first thing Erste noticed was the weapons adorned on the wall, each one of those weapons had a similar feel to those used by the New Gods.

'Trophies of that leader's victories.'

Gratz and Erste continued to walk through the hallway and based on what Erste could see the hallway seemed to be a few kilometers long. The two of them were already walking rather fast but there doesn't seem to be an end in sight. Still, despite already walking quite a long way the weapons adorned on the wall were still plentiful.

'Heh, this leader has killed quite a few New Gods. Now I'm actually getting a bit more excited.'

...

"So how strong is that leader of yours?"

"The leader is not only the brains of our current operation but also the strongest and most elegant among us all... Well, I guess I'm no longer sure about who the strongest is, but I'm sure that the leader is still the most elegant of us all."

"So you think I'm the strongest?" Erste smirked.

"I didn't say that, I said I was unsure."

"Even after seeing me fight that Old God you think that I'm not the strongest?"

"I didn't see you defeat the Old God and I don't really understand your power. I only seen the leader make a move once but even now I don't fully comprehend how powerful the leader is. The only thing I know for sure is that the two of you are incredibly powerful."

"Is that so..."

Simply hearing more about the leader got Erste very excited. The figure of the person he had been looking for flashed in his mind for a second.

...

It took exactly one hour for Gratz and Erste to reach the end of the hallway. Of course at the end in this dimly lit hallway was a door.

"This is where I take my leave. Only you were invited to meet the leader, so only you may enter beyond this door."

Gratz stepped aside as Erste nodded his head and opened the door. The very second he stepped foot on the other side of the door an indescribable pressure assaulted him. It was a different feeling from the pressure he received from the Old God, this one was much heavier as if something more than power was weighing down on him. Still, this didn't scare Erste as he smiled ferociously at the person at the end of the room sitting on the chair his back turned to Erste.

"Quite the welcome you have given me, I like it."

The person sitting on the chair turned around and when Erste saw the person sitting on the chair he was disappointed. All along Erste had this little hope in him that the supposed leader of the rebellion was his long-lost friend, Elena, instead the person sitting on the chair was a gorgeous-looking woman. Long silver hair, dark red eyes, a cold sharp aura, this was nothing like Elena. Still, the disappointment he felt only lasted a second.

"So you're the one who has defeated an Old God. It seems that you're better than expected."

"You too are better than expected."

The two stared at each other, Erste smiling ferociously his confidence shining. On the other hand, the leader of the rebellion had a cold calm expression on his face making one feel everything was under her control.
