Harem Overlord

Kai closed the Sins guide to resurrecting mortals with an interested expression. The details were nice and the entire fifty-page book was dedicated on how to resurrect people on the first seven realms of cultivation.

He put the book back from where he took it and then looked at the barrier as he expected Esmeralda to be standing on the other side of it but surprisingly, she was gone.

Kai stood up as he walked out of the barrier and exited the room. He had to walk around the library for five minutes before he finally found Esmeralda who was sitting on a chair with a book in her hand.

He was about to go ahead and tell her about what he had read when he suddenly stopped as he noticed where her other hand was.

She was holding the book with her left hand while her right hand was inside her clothes and was visible above her pussy.

Kai looked at her for a second before he turned around and went back to the room and let Esmeralda have her personal time.

As he looked at the seven remaining books, he decided to pick one of the white ones to read. The book he picked had a similar title to the last one.

"The Archangels guide to resurrecting mortals." Kai read out loud as he sat down and flipped open the first page of the book.

"If you are someone with an immense amount of life energy, this book can teach you how to resurrect some recently dead mortals with a snap of your fingers. But be careful since this can be dangerous as well. You might end up resurrecting someone you didn\'t want to resurrect." Kai read out the contents of the first page with a small smile as he suddenly got interested in the content of the book.

But before he could read further, he suddenly heard footsteps echoing around the room.

He lifted his face to see Esmeralda standing on the other side of the barrier with gleaming eyes as Kai put the book down and walked up to her. He exited the barrier to stand beside her.

"So what did you read?" Esmeralda\'s eyes were wide open with excitement as she wanted to hear what Kai had read.

"I read something known as the Sins guide to resurrecting dead mortals." Kai replied with a small smile as Esmeralda suddenly grabbed his arm and pulled him after her.

They raced down the various parts of the library as Esmeralda lead him towards a shelf marked with the demon sign.

From the shelf, she searched for a particular book with the tips of her finger as she pulled out a leather-bound brown book from the numerous books on the shelf.

She flipped the book quickly with her right hand as she paused on a certain page and her eyes scanned the entire page quickly.

"Aa explained in the hierarchy of demons, the sins are said to be the strongest demons and have been rumored to have been alive before Lilith the supposed first demon was born. This might point that they were the first demons to be born but it is said that their power is on Lilith\'s level only. It is also said that they lose themselves when their maximum power is released.

Other than that, not much is known about the Sins. It is said that the various demon emperors and empresses throughout time have used the legendary demon sword \'Hellbringer\' to obtain a portion of the power of the sins. One of the old legends also contains that the sins can resurrect humans." Esmeralda read out loud before she closed the book and put it back on the shelf.

"So that was not just a rumor or a legend." Esmeralda said in wonder as she looked at Kai with curiosity on her face as her eyes examined his face.

"Tell me everything in detail." Esmeralda said as Kai started telling her about yen different things he had read.

But after a few seconds, Esmeralda suddenly raised up her hand and took out a pen and a paper from her clothes.

"Write any of the words of this piece of paper." Esmeralda instructed as Kai shrugged and took both the items from her hand.

He then released them from his grip as the pen and paper floated in the air. The pen suddenly started moving on the paper as Kai directed it with his mind.

Esmeralda paid close attention to the words before she sighed and asked Kai to stop writing.

"I can\'t read or listen to anything you write or say. Maybe this place doesn\'t want me to hear all the juicy things in those books." Esmeralda said with a tch noise as she glared at the ceiling.

Kai decided to go back to reading as he left the place and entered the room again. This time, he picked up two books which had the titles - \'Hellbringer - the blood of Lilith\' and \'Excalibur - the sword of heroes.\'

These names belonged to the two most powerful weapons in the entire universe and one of them belonged to the demons while the other to the angels.

Kai sat down and started reading about Hellbringer. The sword was said to be a connection between the Sins and Lilith and has been used for nominating the next demon emperor or empress since ancient times.

But the book said that the sword was useless to a demon, including the current demon ruler, without the connection to the sins.

The sword\'s specialty was that it could give the wielder access to the sins power depending on their connection.

After reading about the sword\'s power and some vast description of the sins, Kai decided to check up on Esmeralda again.

But since he didn\'t want to meet her while she was having some personal time, he decided to just call out her name.

After a few minutes of him calling her out, Kai heard saw Esmeralda coming from the north direction with an annoyed expression. Guess this proved that he had been right about her doing some personal stuff.

"What do you want?" Esmeralda asked while folding her arms as Kai shook his head.

"How long have you been here?" Kai asked as Esmeralda\'s expression softened a little.

"I have been here for more than a millennium." She whispered softly as another question arose in Kai\'s mind.

"How did you get here in the first place?" Kai asked as Esmeralda\'s jaw tightened. It looked as though he had hit a bad spot.

"Maybe we can tell each other about our loves later on. Can you give me some books depicting the seven deadly sins?" Kai quickly asked as her eyes glowed a little.

"Sure, why not." She replied with a smile as she led him through the intricate library.

But little did Kai know that he would spend some years with Esmeralda in this way.
