Sin System: Demonic Harem After Reincarnation

The fluids became colorless as they mixed and bubbled inside the flask the frozen slime was kept in. Lena fluttered over the flask, but flew away when she remembered that it might explode.

Seeing Irene keep her staff in front of herself made Jake take a step back. Was it really that dangerous? He thought to himself, looking at the blue jelly which was getting larger and larger.

”Something is wrong!” Erin said at this moment and Irene nodded.

Jake also noticed that. The slime’s core wasn’t forming. That meant this was another failure… or not. How was it still moving?

Irene threw a restricting potion at the slime. That would be enough to stop it. However, even after this one absorbed the potion, it was still moving. It instead made the Dark Witch its target!

”What?”

The blue slime was extremely fast. It immediately latched onto Irene’s boots. She panicked and cast [Mana Barrier]. However, it didn’t work. The slime with no core was already onto her body. It was eating her boots and… stockings?

”Look, master!” Lena pointed at the Dark Witch whose entire body was covered by that slime.

Irene had thought that it was going to eat her flesh, but the monster only ate her clothing, her hat and shoes included. It also spread to Erin. However, the slime couldn’t do anything to the vampiress because her clothes were made of blood.

Apparently, it could only eat textiles.

Jake had to think hard for five seconds before he decided on a skill to use.

[Demonic Grasp]!

He stretched out his hand and attracted bits and pieces of the slime. However, most of it still stuck to Irene’s body and ate her clothes.

”This…!”

After it made her fully naked, the monster left her on its own. The stunned Irene covered her nipples with her left wrist and her pussy with her right palm. She looked angrily at this slime who now went to her master.

However, the moment it sensed Jake’s mana, the slime tried running away. Jake used [Demonic Grasp] again to keep it from escaping. He then laughed.

”Such a naughty slime!” Lena commented from above in a cute manner, clearly enjoying this unexpected moment. ”Hihi, Irene. You’re naked now!”

Jake glanced at her and pointed a finger. The slime rose to the air and panic appeared on the fairy’s face. She immediately cried and went higher.

”Noooo! Master!”

Erin giggled as she came beside Irene and gave her a scarf.

”You…” Irene was speechless. What was she to hide with this? The witch realized that Erin was teasing her.

She looked at her master. Jake liked the view so he didn’t offer her any clothes. Irene was embarrassed, but she stopped covering herself and coughed.

”I-I’m sorry for this, master. I will make a real flesh-eating slime…”

”No no.” Jake clenched his fist, turning the spread out slime into a single ball of blue jelly. ”This is useful…”

He used [Magipathy] and found small, invisible nuclei on this slime’s body. He could destroy one nucleus, but it would regenerate another. To kill this monster, one had to destroy all of its nuclei at once.

Now, that was interesting. Jake first tried using [Enchantment], but he realized midway that the monster wasn’t sentient. He used [Degeneration Halo] and put a corrupted seed in one of its nuclei to control it.

Unlike other times, this was still not permanent. If someone destroyed that particular nuclei, the slime would still live out of his control. Even Jake’s overpowered control skill had limitations, it seemed.

”Have you noted the procedures you performed while making this?” Jake asked.

”Yes, I’ll look into what went wrong,” Irene put her hands behind her back and replied.

”Try to replicate the process which makes the slime like this. Use your mana sense to look inside its body.” Jake pointed his finger at Irene and the slime flew toward her.

She instinctively backed away. Jake and Erin laughed again. Above them, Lena heaved a cute sigh and flew out of the room.

Some time later, Irene wore a red robe. She and Erin headed out of the experimental chamber with their master. When they reached the core chamber, Jake realized his tea had become cold.

He sat on a sofa in the living room and looked around. Riri was making something else in the kitchen with two village women.

Jake examined his inventory at this moment.

[Mana Crystals]

[Low-grade: 2,109]

[Mid-grade: 782]

[High-grade: 290]

[Super-grade: 0]

According to his dungeon fairy, to advance the dungeon from Tier 1 to Tier 2, it took 250 high-grade mana crystals.

It seemed the time was near.

Ten minutes later, Jake sat on a sofa, sipping coffee. Of course, the villages here didn’t have the coffee beans. He had brought a package from his system.

Beside him, Perry sat elegantly, crossing her legs. She had a report of the dungeon’s inner development on her hands, but her master was more interested in holding her waist.

”Where is Yunna?” Jake asked, taking the report from her hands. Perry shook her head, she didn’t know where the succubus went.

”She, Diana and the priestesses have gone to bathe, master.” Amelia, the catgirl replied.

”Come, come here.” Jake waved at her and she walked toward him. He patted his lap, telling her to sit.

After she sat, Jake made her lean on his chest and stroked her belly. Amelia gradually started purring. She was one month into pregnancy. Rose, Niru, Vin, and Elena were the earliest to get impregnated by him. They were already 2+ months into pregnancy.

However, it seemed as if 4-5 months had already passed for them. This rapid growth stunned him. Jake’s women needed little nutrition, and they seemed energized just by bearing his babies.

Him being a demon had played a major role in this. Jake’s semen was more potent and had greater vitality than a human’s. If that was so, then it wouldn’t take long for them to deliver babies. Maybe another two or three months.

The same could be said for all the pregnant women in the three villages.

‘Does that mean the babies will also grow faster? They have my demonic genes even though I didn’t give them my powers…’ Jake thought, sipping his coffee. He was curious about what would happen if he bought a bloodline.
