The unnamed dungeon was elated about the bonus skill experience he received, which increased several of the skills he had used the most. Naturally, he was also a bit depressed that he didn't wait longer, as he surely could have increased even more of them.

He was extremely bored during the periods of waiting for his mana to recover, and was disappointed that increasing his level didn't increase his mana recovery speed.

Once his mana was mostly full, it was time to test out the biomass converter, which appeared to be made out of some kind of mana constituting black flesh that wasn't really flesh. It cost mana to operate, in which black tentacle and black knife tentacles would cut up the biological creature and pull it in for further processing into a base, organic material.

Coming up with an excellent idea that only a dungeon could, he created another pitfall trap in the existing one, this time it was lying on its side in the wall. As a pitfall trap, it was a failure, but it allowed his to move the biomass converter inside of it, which he could then manually open the door and allow it to process whatever dead animal or other creature is inside of it.

A supreme, grand design the he-dungeon flexed his third vertex over.

After moving everything into place, he watched in pride as the biomass converter extended its flexible yet sturdy black tentacles to carve up the bear.

The sound of hacking flesh and grinding faintly rumbled in the small cave. It was a very efficient machine and finished processing the bear in about ten minutes, the entire thing converted into 15 units of biomass, giant bricks of pink fleshy substance. Unfortunately, it couldn't clean up all of the blood left in the base of the pitfall, so it was quite a few inducing appearance.

He had some knowledge on organic matter, so he knew it could spoil, but he believed biomass should last longer than a festering body due to lack of bacteria. That wouldn't stop more from infesting it though, so he made sure to store the biomass inside of his Internal Resource Storage. This should allow it to keep for the longest period of time.

With his former prey gone, he had to do what dungeons do, lure in prey.

With biomass in his storage now, he created some bait, which turned out to be a pile of fruits and raw meat. His only source of dissatisfaction was that it was messily left on the ground, it would be much better laid out on a platter, possibly some sauce or dressing to go with it. This was meant to lure prey in after all.

His dungeon-y senses knew how to dungeon far better than the skill it seemed.

He was also dissatisfied with the price to product ratio of the dungeon skills. 5 units of biomass was half a cubic meter, or five of those giant bricks, yet this amount of food didn't even amount to one of them in mass.

He couldn't leave the food like this, so he created a stone platter with some swirling patterns engraved in it and used his dungeon senses to slide it under the food pile, directly after the pitfall trap.

'They want to steal my food? This is five units of biomass! They aren't worthy!'

~~~~~

The following two days passed by rather uneventfully. The food was laid out on display, but the prey lured in weren't anything great.There were four rabbits, which only gave 2 exp each and were incredibly difficult to kill with a spike trap, one deer, and what looked like a black jungle panther. The final one stalked into the cave the night before and was so agile it would have jumped straight out of the pitfall if the lid was closed any slower.

The experience with the rabbits had led to an upgrade in the overall pitfall design, not with spear traps on both sides of it, while the biomass converter was moved to another side. With double the spears, there was double the chance to hit small targets, and double the damage to large ones.

The genius design became even more genius.

The dungeon had expanded considerably, with several room-like caverns behind the basic entry tunnel. Three large rooms in a triangle formation, each filled with lots of pitfall traps. Most of them were filled with resource bricks, but some were replications in the pitfall + spear trap. It had scanned the first one and auto built them again.

There were more spear traps on some of the walls and even the ceiling, to catch anybody searching for pitfall traps unaware.

+ New Subskill: Mineral Detection

'Ohh, so that's what they are called, subskills… what about traps and such? Subrecipe?'

The young dungeon overlord felt the subskill start working immediately. It could feel the surrounding earth near its dungeon like it had a sonar. All that currently fed back from the subskill was stone and dirt, but it would be much easier to find metals and other treasured materials buried in the ground with this skill.

Just then, the he-dungeon felt several large entities enter itself. Focusing its attention on the entrance, it saw three humans enter. Two were males, one with a torch and an iron sword while the other held just a sword. They were equipped with worn leather armor and had rough appearances like bandits. At least, that was how the dungeon imagined them as.

The third person was a woman in torn clothes, exposing decent patches of skin, including her left breast. She had long blonde hair, but that had blotches of mud in it and was full of twigs. She was bruised and beaten up, but definitely a complete beauty.

The dungeon quickly noticed something else off about that woman. She had elongated, pointed ears that poked out from the mess of her hair. She also had what looked like an iron collar around her neck.

'An elf! This world has elves!! Wait, why am I thinking that?' The dungeon thought to himself before an overwhelming sense of possessiveness overcame him. 'I must have her!'

"azosvvt opkq"

The two humans pushed the female elf into the dungeon in front of them with some garbled words the dungeon couldn't understand. It did however, feel a strong hostility against them the moment they entered inside itself, so understanding them was highly irrelevant for it.The elf stumbled forward almost lifelessly. She walked further into the dungeon, ignoring the delicious looking food platter altogether. She was extremely nervous, often coming to a stop before the two behind her pushed her forward again and cursed at her.

She didn't say anything back, simply walking forward as if walking toward her death.

What she didn't know, was that despite its hostility, the dungeon was feeling a strong sense of possessiveness toward the elf.

The two men behind were also unaware, merely lighting up the path in front of them on constant alert for monsters or traps.

There were no monsters in the dungeon but the genius dungeon had dungeoned countless spear traps everywhere, turning the entire place into a death trap.

Just as the trio entered the first room at the back, the floor dropped out just behind the female elf. One of the men managed to jump back just in time, but the other wasn't so lucky. He dropped directly into the hole with a shout and a curse before a faint 'shua' sounded and 40 stone spears shot out from the wall.

This human clearly wasn't to be underestimated though, he responded with lightning reflexes and swung his sword at the stone spears which shot out from the wall in front of him, breaking most of them before they could cause any damage.

He was still unaware of the ones which came from behind though. His armor softened the blow from most of them, but plenty still struck in unguarded areas.

The dungeon was expecting him to die from that, but despite being stabbed considerably deeply in many locations, he was still alive, cursing and capable of moving.

The second man went to retreat quickly, but the dungeon had already released three traps around where he was. He tried to dodge away further and break several spears with his sword, but he couldn't hope to defend himself from three directions at once.

The dungeon retracted the still intact side of spears and quickly finished off the first man, while the second was already dead from an unlucky spear which pierced his temple. It didn't matter how sturdy his body may have been, that strike was fatal.

'Ohhh! One of them didn't just look like a bandit, they WERE a bandit! I can also level up again, but I'll make sure to wait longer this time for a bigger bonus!'

The dungeon made a victory dance, or a victory spin, as it looked at the two corpses. All that was left left was the dirty elf maiden who was curled up on the ground shaking in fear.

'Well, she's mine now. But… how do I talk so I can tell her what to do?'
