Kaiden zoomed the map view out, measuring in his head like a true min-maxing gamer. He was happy to discover that the 100 meters of space only had to be honored horizontally, not vertically. He could place the cavern right at the foot of the dungeon gate, meaning 0 meters had to be honored downwards, and only 3 meters (9.84 feet) had to be honored upward.
This meant that he had to give enough space for a tall, muscular man to walk without scraping his head. Furthermore, he tried to make the path so narrow that even Luna would struggle to fit through, but he was once again stopped.
The cavern pathways had to be wide enough for at least 2 people in armor and swords in hand to walk next to one another.
It was a bit sad, but Kaiden wasn’t annoyed. He now understood that being a dungeon master wasn’t just about ensuring no one could ever win. You had to play the dungeon game by the rules... Which meant giving the invaders some chances of success.
However, this was still more than perfect compared to what Calypso had before.
He didn’t want invaders strolling in comfortably; he wanted them to feel confined from the first step.
But before letting himself feel good about his decisions, Kaiden decided to test it out. He did not allow himself a false sense of security.
He needed to test the rock.
Kaiden raised his hand. His Blood Monarch’s Gauntlet responded instantly. Blood gathered in his palm, forming into a crimson pickaxe. It was dense, perfect for the job.
He lifted the pickaxe high and brought it down with "[Doomrend]!" The impact echoed like thunder in the silence. The rock didn’t crack. A faint scorch mark spread where the pick struck, but no fragment came loose.
Kaiden’s eyes lit up. "Oh?"
He hit it again. And again.
For several minutes, he slammed his weapon against the abyssal stone, each swing powered by mana and muscle alike. His blows shook the air, sparks of red energy dancing across the black surface. But when the dust cleared, the result was the same: no dent.
Not even a scratch.
"Amazing."
Sweat beaded on his brow, but Kaiden was relieved.
"That explains the price tag."
He’d made the right call. Regular stone could be tunneled through by miners or awakened with earth-type skills.
Since he had to provide the invaders with a safe zone, they could just enter, realize it’s a cavern-type dungeon, go back out, and come back with proper tools for the job, such as enchanted pickaxes, blessed with durability, reinforced with mana, to dig alternate paths.
This would let them bypass the path Kaiden intended his invaders to be forced into traversing.
But abyssal rock?
No chance.
They could swing those enchanted toys all day long, and they’d dull before they left a mark. Unless someone possessed obscene, god-tier strength, this wall wasn’t getting breached.
He leaned against the unblemished surface and grinned. "Freaks like the Heavenly Demon might have the tools or just raw power to break through something like this, but my concern right now is humans."
Kaiden didn’t doubt that he’d have to face mightier enemies in the future, but for now, he had to prepare for what he knew were the most imminent threats.
He dismissed the pickaxe, the blood evaporating into mist as he wiped his brow.
Even just testing the stone had been satisfying. Feeling the feedback of his blows, the satisfying resistance of the dungeon... it scratched that primal itch deep inside him.
He couldn’t help but chuckle. "Man, I wish the girls were here to see this."
His voice echoed softly through the empty cavern-to-be.
