Harem Overlord

"Sierra are you sure about this?" Kai asked one last time as Sierra nodded.

Kai then put the crown on his head as a black glow slowly surrounded his body. He closed his eyes as he slowly started levitating in the air and Sierra could only look at him with a smile.

A wave of power went around the room as Kai's clothes turned to pure black. He opened his eyes and they too had turned black in color though only his irises had turned black.

His hair also slowly turned pure black as he landed on the ground with the crown hovering over his head. Then with a flash, his appearance changed back to normal as the crown stopped glowing.

"Congratulations Kai, you are now the elemental ruler of dark." Sierra said while clapping as Kai remained silent.

"Sierra, you were actually a spy?" He slowly asked as Sierra's eyes turned sad and her body started shimmering.

"Guess you inherited my memories as well. And yes, I was a spy but I had stopped doing my duties long ago." She replied as Kai looked surprised.

"Are you about to reincarnate somewhere else?" Kai asked as Sierra nodded.

"I hope I reincarnate in a peaceful place again but perhaps a little action isn't that bad." Sierra said with a wink as she raised her right hand forward for a handshake.

Her body glowed brightly and slowly started vanishing away as Kai took a deep breath and raised his right hand forward. He shook her hand with his hand as Sierra smiled at him.

And with that, her entire body vanished.

"Farewell, my friend." Kai muttered as the crown on his head started glowing again. He then sat down on the floor in a cultivation pose before his body started hovering in the air.

He closed his eyes in focus as the crown of night started to glow more fiercely. Its glow illuminated the entire room as Kai's cultivation started rising again. He could feel his soul starting to burn inside his body as he slowly advanced to the semi-divinity realm.

Kai then opened his eyes as they started glowing golden in color. His black demon blood and the previously golden-colored angel blood slowly entered his soul as ichor filled his veins.

A small half-white and half-black sphere appeared in front of Kai's face. The sphere was his soul which had turned into a sphere. After he would advance to the spirit immortality realm, the sphere would turn into his soul.

Now that he was at the semi-divinity realm and was also the elemental ruler, he could easily go to the palace of elements. Obtaining the new power and advancing in his cultivation had already made the side effects of the pill vanish.

Kai then sent spiritual messages to Inari, Mizaki, and Hela and asked them to come back in the room.

But when the three of them came back, they felt that something about Kai was different.

"So listen carefully, we are leaving for the palace of elements right now so you guys should be prepared for anything to happen. We are going to travel there manually since anything might happen." Kai said as the three girls looked confused.

"What about the pain you were having?" Inari asked as Kai shook his head.

"The pain is gone now." He replied as Inari still looked confused but didn't say anything.

Seeing that they didn't have anything else to say or ask, Kai teleported them out of the sect and they appeared at the border of the continent of water.

"I can teleport us out of here to the edge of the continent of fire and after that, we will have to travel while flying." Kai said as they vanished again and appeared at the edge of what Kai had called the continent of fire.

After that, all four of them rose in the air as Kai put invisibility barriers on them and they started flying straight forward. They traveled like this for a few days but only saw the ocean and nothing else.

They had left the continent of fire in their trail long again but had no idea how far this palace of elements was. While traveling, Kai had also been seeing Sierra's memories side by side.

The movement he had found that she had first been working as a spy for the creators had been a shocking movement for him though he should have guessed that this would be the case.

But this made him wonder about another thing as he glanced at Mizaki from the corner of his eyes. 

'What if she is a spy too and we are somehow going to be led into a trap?' Kai wondered silently since there was a possibility of his theory being true.

But there were still some chances that his theory would be wrong so there was no way for Kai to confirm, it. He then glanced at Hela who looked normal but just to confirm, that everything was all right, Kai kept glancing in her direction every few minutes.

He then looked at Inari as he released a low sigh before looming forward. Inari was a really stubborn woman that's sometimes made Kai wonder what her motive was.

'I wonder how Inari used to be in the past. I will ask her about it later on and see whether she is willing to tell me anything.' Kai thought silently as he closed his eyes for a second to peer at his soul sphere.

He could see his soul sphere hanging in the center of his half black and half white soul. The soul sphere was hanging exactly in the middle of it which meant that Kai was in perfect balance.

But one thing that caught his eye was that Sierra's crown was also hovering beside his soul sphere.

'No, that crown no longer belongs to Sierra and is my crown..' Kai thought while exiting his soul space but his moments spent with Sierra still lingered in his mind.
