Sin System: Demonic Harem After Reincarnation

Some time later, Jake was on the 10th floor.

He used his senses to check and found which chamber Isa was in. Jake flew through the corridors and found spiderwebs all over. Ever since the demon spiders moved here, the goblins had to contest for territory.

Flying through the beehive like underground tunnels, Jake saw spider babies hiding in every crack.

Jake had expended more than 10 mana. However, as he was inside his dungeon, he could replenish it quickly.

Whoosh!

Jake appeared in a large chamber after passing through all the tunnels. He saw the spider queen there. She looked surprised when he flew inside.

Jake glanced around and saw the chamber was cold and white. With the spiderwebs plastering the wall, it looked like the insides of a cocoon.

"Master." Isa stepped forward.

Due to the appendages protruding from her back, she walked rather slowly. Swaying her hips for balance, as if she was a model.

Because of Lena's pestering, Isa had barely covered her nude body with her webs. It looked like an extremely short, white one piece.

"I can't lay eggs, master!" She seemed distressed.

Isa grabbed her breasts and looked at Jake.

"This body is weird. After my evolution, my abdomen changed and became like this..." she touched her belly and then her slit.

Jake immediately understood it. After gaining a fully humanoid body, her reproductive organ was very much similar to a human's.

Though Jake didn't know much about it. If she couldn't lay eggs then her spider army wouldn't increase at all. The demon spiders were incredible assets for Jake.

He had invested a lot in this Spider Queen, and couldn't just let her be. For his dungeon, she had to reproduce.

"You see, Isa. I had always been meaning to try out an experiment with you," Jake said in monster tongue.

"An... experiment?"

"Indeed." Jake landed on the ground and walked towards her.

"Let's see how your new body reacts to this."

[Ding! You have equipped the title "Pleasure Demon." Females within a 50-meter radius from you will be aroused.]

...

Boom!

Lightning lit the northwestern Karsuda's skies.

In the periphery of the moonlight forest, there was a large abandoned mansion.

Its architecture was gothic. Despite being located in a lush forest, not a single blade of grass could be seen near it.

Any type of plant that grew here died in a heartbeat. Insects lay dead on the ground, and the land looked infertile.

The whole mansion had a gray aura to it. Its insides were usually dark and silent. But today, a pair of dark blue fireballs lit the main hall.

Burning on the empty eye sockets, the fire illuminated an outline of a large skull.

"My Lady, our forces are ready." A magical voice resounded through the air. It was deep and grating.

"Oh?" A crisp female voice responded.

The owner looked to be a young, oval-faced woman in her early twenties. She had long black hair, silver eyes, a short and pointy nose. Her neck was long, and her chin was rather thin.

The most prominent feature about her body was her pale skin. Unusually pale, as if she was a corpse.

The woman was of medium height. Wearing a dark robe did not hide her symmetrical, almost perfect proportions.

Any man would turn his head more than twice to appreciate her beauty and curves. This woman liked her body and the attention she gained from it.

She was obsessed with her youth. So much so that she had zombified herself.

"Pass my orders to gather the undead soldiers." Countess Minerva ordered her Death Knight.

People liked to call her a powerful mage, but she thought of herself as something more. More powerful, fearsome, and prestigious in the magical community.

Minerva was a necromancer in the pursuit of true immortality. A crazed woman who sacrificed everything past her 20s by turning into a zombie.

She wanted nothing more than to live forever. For that purpose, she was willing to do anything. For a single drop of Life Elixir.

Minerva knew her zombified body would rot away soon, it had been 5 and a half years already.

Only her vast mana sustained her precious youth. The mana she gained by sucking the life force out of the living beings. If only she knew how to turn into a vampire...

She made a mistake by becoming a zombie and the Life Elixir could correct it.

"Even if it's at the hands of the king, I will take it."

The Grimbow kingdom wasn't that strong of a nation. Even the royal family only had three 4th Circle mages and a 5th Circle Radiant Knight.

Minerva hit the ground with her staff and a huge magic circle appeared beneath her.

Cries of agony and pain came from the magic circle. Dark, skeletal hands dug from the ground.

The countess chanted and more hands appeared. As she kept chanting, undead warriors lined up in front of her.

Minerva walked ahead and her summons followed. An army of undead soldiers were outside, staying silent as the rain poured on their rotting bodies and skeletons.

Two thousand strong undead. Most were unranked. Yet more than 300 of them were 1st Circle undead. Sixty-seven at the 2nd Circle and twelve at the Third Circle. Death Knights, Undead Warriors, Skeleton Mages... All controlled by an elite 4th Circle Necromancer.

This was a fearsome army as strong as ten thousand humans. And Minerva was going to create a storm in the Karsuda province and the whole of Grimbow kingdom with it.

She had been preparing for this day for 5 years. And only now she learned the elves had hid their treasure right here in Karsuda.

Someone among the nobles had it.

Flying over, the zombie necromancer sat on one of her Death Knight's shoulders. She pointed straight ahead and the undead marched.

Her first destination was the fief of Count Werbner.

Unknown to everyone, a calamity was coming.

...

In the dungeon, Jake looked as the Spider Queen moaned uncontrollably. She tore the web covering her pussy and began rubbing her clit.

Slipping her fingers down, she inserted one into her hole. Isa could not understand why she was doing it.

He had not taught her anything, yet she was already pleasuring herself.

"You can still make babies, but they would be a bit different..." He held her waist and grabbed her fleshy ass.
