Sin System: Demonic Harem After Reincarnation

He immediately called the system shop and scrolled through the [Items] section.

”Potion… Potion… Willpower Potion…” Jake muttered and suddenly shouted in frustration. ”Damn it, I fucking need a search- Oh, there it is.”

He bought ten bottles at once. His hands trembled as he pulled the cork like a drug addict. However, he suddenly went into a trance, forgetting how to even drink from that small glass bottle.

”What am I even doing?” Jake sighed and sat on the ground. Everything seemed meaningless.

That feeling was very similar. With no ambition, without any drive. He pictured that day he left the college on earth. The day he crossed the street. Jake could hear a truck’s loud horn and that suddenly brought him out of the trance.

”Hah… Hah… Fuck.” He breathed hard and kissed the potion bottle’s mouth.

When he finally chugged the sour liquid down his throat, Jake found his will rising.

He stood up and drank another bottle.

‘I got careless.’

Jake looked at the monster women who were in their true forms. He pulled the gorgon with [Demonic Grasp] and asked with a sharp glint in his eyes, ”What are you two doing among humans?”

[Ding! Congratulations, one of your skills has leveled up!]

[Demonic Grasp (lvl. 7→ lvl. 8)]

Ruxa didn’t have a shred of pride on her face now, only fear and reverence.

”We are traveling to the new dungeon that has spawned in this province. It is the order of my mistress.”

Her answer surprised Jake. It appeared news about his dungeon had spread all over Grimbow Kingdom by now. That meant people in the capital and the other provinces were also aware.

”Who is this mistress you speak of? Where did you come from?” Jake asked again.

At this moment, the lamia spoke.

”We belong to a tribe of snakes living in the dungeon near Saelther Canyon. We came from Ardin. Our Mistress, Nyssa, is a Fourth Circle Gorgon and the head of our tribe.”

‘Another dungeon?’ Jake thought. It must be a Tier 1 or higher dungeon to accommodate a 4th Circle beast.

Suddenly, Jake noticed that quite a few people were regaining control of themselves. He checked his Evil Points and found it still increasing every second. The rate was slow, however.

By now, he had already amassed over 200,000 points. He was getting less and less. That meant the people had already sinned a lot. Now they had less value to him alive.

Jake flew to the sky and looked over the town. The previously peaceful Regis was nowhere to be seen. In its place, a new Regis, full of disorder and crime, was on display.

‘I guess that’s it… System, start the Advancement Ritual,’ he commanded.

A prompt appeared in front of him which told him how many inhabitants he had killed. At the same time, it told him to keep a blood array and some mana crystals ready.

Jake swiped it and pointed his finger below.

[Icicle Rain]

The mana density here was thinner than in the dungeon, so it took some time for water droplets to condense. Jake had to expend more of his own mana to accelerate the process.

Su! Su! Su!

Sharp icicles fell from above and pierced the bodies of the people who were regaining their rationality.

Some cried in pain while some didn’t even get the chance to. Blood froze on their wounds made by the ice. Jake took out his scythe and descended like a god of death.

He swiped his Black Reaper at anyone he saw. Men, women, children, infants… He didn’t spare a single one and slaughtered them for his selfish purpose.

Crying souls rose from the corpses and followed Jake. Hot blood of the dead people splattered on his body. Horns emerged from Jake’s head.

The lamia and the gorgon felt chills run down their spines when he looked at them.

”What use do you two have for me?” He asked, holding a little girl.

The two monsters didn’t know what to say. What use, indeed.

”W-We are powerful, unlike these humans…” Ruxa said.

”Wrong answer.” Jake crushed the little girl’s head, abruptly cutting her ear-splitting cry as her skull bursted.

He threw the lifeless body on the ground and flew to the two monsters.

”I can offer my body to you, demon master.” The lamia quickly tried saving herself.

Jake stretched his hand, and she flew to him. Catching her chin, he smelled her hair and licked her neck.

”Offer your soul to me.”

The lamia bit her lip and bowed in submission. As Jake had already depraved her mind, she would listen to his every command.

Jake wanted her 3rd Circle soul. He swung his scythe and its blade cleanly cut her head. Sapheisa’s lower body violently trembled. Her snake tail kept hitting the ground and stopped moving after a while.

Although it would’ve been fun to fuck a lamia, he could always do that later. She wasn’t the only one in the world. Right now, the boost of a powerful soul would be better for his advancement. This quality simply couldn’t be compared to unranked humans.

The lamia’s aggrieved soul rose from her dead body. She joined the souls below Jake who were trying to hold him with their ethereal hands.

Ruxa’s face paled, and she jolted when Jake turned to her. To her surprise, he didn’t kill her.

”Your use for me isn’t your puny power, nor your soul. It’s your knowledge of that snake tribe and that dungeon.” Jake swung his scythe at the empty air, cleaning the blade off of the lamia’s blood.

”Always remember that you, your whole being belongs to me. If I want to fuck you, you will spread your legs. If I want to kill you, you will bring me your neck. If I keep you alive, you will rejoice.”

”Yes, m-master,” Ruxa shuddered as she replied.

Jake turned around and glanced at the system screen.
