Sin System: Demonic Harem After Reincarnation

Jake ordered the harpies to go direct the monsters remaining on various floors. Most were on the 45th floor along with the Demon Spiders.

He had been lax earlier and let them stay on lower floors even though they weren't that powerful. However, leaving the upper floors empty wouldn't do good.

After hearing him, Iona and Ciara, the harpies who controlled the group, flew to inform other monsters.

Isa, the Spider Queen, also called her children. By now, she had laid thousands of eggs. A lot of spiders had already entered the adult stage.

She now had thirteen 2nd Circle and fifty-six 1st Circle Demon Spiders in her family. That number would only increase as he kept breeding her.

As the spiders began moving, the remaining goblins, gnolls, lizardmen, kobolds and wolves quickly learned of the Dungeon Master's order.

This would most likely be the last time they moved from floor to floor. Since Jake first expanded his dungeon half a year ago, they had to move around a lot.

It was his mismanagement as the Dungeon Master. Thankfully for them, Jake was planning to be thorough this time in allocation of monsters in various floors.

…

On the 1st Floor of Dungeon of Sin

''Slimes are one of the weakest monsters and usually in the lowest hierarchy of monsters. Keeping them here would be the best," Minerva said, waving her wand at the blue and green blobs of sticky liquid which Jake had 'magically summoned.'

These slimes directly fed on mana or anything that had mana in it. There were lots of demonic plants around like the Man-eating Flowers, Silent Leaf Teeth, and Shadow Wines to keep the slimes in check.

Jake added some giant rats as well. These were violent omnivorous creatures which mostly preferred human meat. They would be troublesome for newbie adventurers.

The 1st Floor didn't need to have many monsters. There were a few traps here and there. Jake, Lena and Minerva descended to the 2nd Floor.

There, he finally began spending sizable sums of Evil Points.

Mud Scorpions, Poison Centipedes, Blue Frogs… They cost him more than 6,000 points. Minerva also made him add a mini floor boss. Jake bought a large Clay Puppet and put it in a chamber which led to the lower floor.

Anyone who wanted to reach below would have to defeat it. But with the dungeon's mana, the puppet would respawn in about two hours as long as its clay remained dry.

On the 3rd Floor, Lena suggested that he make one pack of monsters dominant over the other. After much thought and talk with Minerva, he bought 400 Sleep Moths and 20 Metal Mantises.

There was a trap room on this floor where most moths would stay. But a secret path to avoid the moths was also there, where the mantises would be waiting.

''Think about it,'' Minerva came forward and pushed a random stone on the right wall. The trap room opened and the Sleep Moths tried making her fall asleep with the dust on their wings.

''They will feed on the nectar of the demon flowers here while the mantises,'' She turned and threw a fireball ahead.

It illuminated the bodies of some Metal Mantises which Jake had just bought.

''They will feed on these moths.''

Lena seemed unimpressed and flew ahead. The monsters there immediately recognized the authority of the Dungeon Fairy and didn't attack her.

Jake and Minerva followed her from behind. They reached a large open area with crude stairs leading down.

The third floor would not have a floor boss. Minerva's logic was to give the adventurers a breather so they would be more willing to explore deeper. It was to trap them among the dangerous monsters in the lower floors.

After the 4th one, the size of each floor drastically increased the deeper they went. Minerva suggested they added floor bosses on each one.

She also very annoyingly said how other dungeons had some type of reward on each floor. As Jake bought more, he realized his more than two hundred thousand Evil Points wasn't much at all.

Time passed and he kept surprising Minerva more and more. He had reached the 11th floor, adding demon wolves, goblins, shadow bats, serpentine monsters, elementals, etc.

To this immortal zombie, Jake was more magical than any mage.

''Where do you even… bring these from?''

Jake didn't reply to her. He had spent most of his points by now. Only 30,000 more remained. That would be enough for the lower floor at most.

He would have to amass more points to fill the lower ones. Well, if he had haphazardly bought monsters without Minerva or Lena's suggestion, he would have filled 20 floors.

But that meant he wouldn't have the balance needed for a sustainable food chain. Jake had also bought various low-grade magical artifacts. The points were well spent.

''Let's go to the 12th floor,'' he said.

It had been more than 16 hours and Lena wanted to rest. However, her master and this beautiful woman were hell-bent on getting this done quickly.

''This will be the last one for now,'' Jake said, descending through a flight of far-reaching stairs.

He could see the 12th floor below. This place had a different air to it. First of all, everything was foggy and cold here. There was a forest.

Jake had already planned the floor boss for this place. Using his authority as the Dungeon Master, he called the Hell Knight who was staying on the 18th Floor.

Now that his dungeon had various 3rd Circle Monsters already, the Hell Knight wasn't that unique. However, he would still be a terrifying enemy for even D-Rank adventurers.

''For this floor, I think trolls would be the best choice.'' Minerva looked around.

In the Whispering Labyrinth, the 12th floor had golems. But that wouldn't work in such a terrain.

''I think…Dryads are a better choice.'' Lena flew and sat on her master's right shoulder.

'Yea… if only I could afford them…' Jake chuckled internally. Dryads were a type of nymph and obviously ranked higher in monster hiercharchy. He wasn't even sure if the system had them.

Jake scrolled for quite a bit of time and finally found Forest Trolls. Each one cost him about 700. Just buying 30 took 21,000 Evil Points.

Once he bought them, the monsters immediately appeared around him in small packs of 3. Upon his orders, they spread around the foggy forest. These trolls could eat anything, so there was no need to bring another group of monsters.

With this, the first 12 floors were done. Jake closed his eyes and focused. He found that the other monsters had reached the 31st Floor.

They still had to climb higher. None of these monsters deserved a floor lower than the 20th one.

''Now, I need to sleep!'' Lena puffed and quickly turned into a green speck of light, heading straight for the Dungeon Core.
