Demon King Who Will Rule the Infinite Worlds

Aura Furnaces were talented servants kept by the Nobles. Although the term was degrading, it wasn't that big a problem. For Demons who devoured emotions to increase their aura, it was necessary that their partner didn't harbour hate or negativity in their heart. If one did, then it led to backlash. It could be poisonous. It wasn't worth the trouble.

It kept them safe, despite being turned into slaves. Under King Aurum's rule, they were in a better position. There were only two downsides to being an Aura Furnace. Enslavement, and that they couldn't equally share the benefits of training. All benefits that would normally be shared would go to their Master.

From what Eve understood about King Aurum from his adventures in the novel. He wasn't the fan of Aura Furnaces, but the tradition was deeply rooted among the Demons. Every successful Demon kept a team of Furnaces who were their most loyal subjects. With their Masters success, the gains from training would lead them to gain a massive jump in powers that many could only dream.

It also led to many organisations to pop-up which trained and allowed these Furnaces to choose their Masters. There was even a festival where Knights gathered, hoping to gain a talented Furnace under their belt.

'It isn't easy to get rid of something that everyone does and wants. On top of that, Demons live far too long and their reproduction rate is too small. If a Furnace gets pregnant or impregnates their master, they could even become husband and wife and end their slavery. A bond like that rarely breaks,' Eve sat on the Throne beside King Aurum, wearing a lavish black and blue dress.

"Your Majesty, where are these people coming from," Eve noticed the expecting look on Aurum's face. There was one time in the novel that Aura Furnaces were brought to him and he sulked the entire time. This was completely different.

"From the human world," King Aurum happily answered, but his answer made Eve freeze up, unable to believe her ears.

'Human world? The world I am from,' Eve nervously gripped the throne's arm. She was a Ranker from front lines. People had seen her transformation, she was too famous and currently she looked exactly how she looked transformed.

She was famous to the point she couldn't leave her house without ten guards keeping people away from her. It was the whole reason she liked staying at home and reading novels or watch shows in free time, 'No...what am I going to do...what if His Majesty learns of this? And Big Brother...'

She bit her lip, thinking about leaving her when the King looked to the side, welcoming his Son, Arthur, "Arthur. Come, stand beside me."

Arthur nervously looked at his father, then the place beside Eve, making King chuckle, "Or you can sit in your mothers arms."

"No way!" Arthur hurriedly shook his head, standing beside Eve's throne, "if I were among the people coming then I would look down on the rich boy sitting on his mama's lap."

"Would you now?" Aurum lightly chuckled at his cute reply. He whispered in Eve's ear, "Isn't he adorable."

Eve tried to calm herself, a smile adorning her lips, "He is. Your Majesty."

"You look lost. Anything I can help you with," Aurum placed his palm on hers, gripping her fingers, "Is it because of Aura Furnaces?"

"No, I am curious about Human World...what kind of place is that?"

"Depends on which world it is."

"Which world," Eve snapped her eyes up to meet his. There was something wrong, there wasn't a storyline related to otherworld. Not at the point in series where she had read to, "there is more than one?"

"You don't know. That's surprising," Aurum stroked her fingers, "At the Northern Edge of the world likes the Sea of Fog. It is too thick to travel by the Demons, the monsters inside are too dangerous. It's forbidden lands that none of the nations dares to step on."

"I know that. Many tried to explore that area but failed to do so," she whispered, "Too many people have died there."

"Well, Camelot developed a technology that allowed our ships to travel through the Sea of Fog. In the depths of forbidden lands, we found cracks in space and time. Warp gates that lead to other worlds. The people coming over are from the first world we found," King Aurum keenly stared at the door, trying to be patient, "I can't wait to see. Being from another world."

Eve nervously gripped the throne's arm. She felt slightly better, there was still some hope that these humans wouldn't be from the world she was from. The best solution she could think of was leaving the Throne Room. If her husband was anyone else but King Aurum, then she would have done that. Sadly for her, 'he's too sharp. He already knows something is bothering me and I have no good excuse. What am I going to do?'

"Eve."

"Yes, Your Majesty?"

"Believe in me?"

Eve parted her lips. She shifted her eyes to meet King Aurum, who looked at her with the calmness she had always found terrifying and relaxing. She rested her head on his arm, "I will, Your Majesty."

She felt much better. It didn't matter if he found out, 'maybe I should tell him one of these days...but I have to think about Big Brother too...how would he feel?'

She closed her eyes, soon hearing the door open and footsteps marching down the throne room. Her hand was tightly gripped by Aurum's hand. She opened her eyes to look at the group of humans being brought in shackles. They looked clean and well-fed, filling the massive throne room, huddled together under the gaze of King.

'That's the difference,' Eve always felt there was a clear difference between Demons and humans. Now that she had both in one room, she sensed it. Humans looked too fragile in front of Demons. Her eyes were drawn towards the towering woman. She was as tall as the King, about 6'4, her massive breasts shaking with every step she took, her face covered in a grin, "Your Majesty! Your favourite Sea Amazoness is back with your priced possessions!"

"Welcome back, Marchioness Millsack," King Aurum smiled at the woman who knelt down in front of him, kissing the back of his hand, unable to tear her eyes away from the King.

'Her name is Millsack...Milksack suits her more,' Eve kept her thoughts to herself, keeping them from showing on her face. 

"Eve, this Marchioness Marirosa Millsack. She commands one of the Sixteen Fortresses that protects Camelot's borders. Fortress Marirosa."

"Yes. Queen," Marirosa happily invited Eve, "My Fortress protects the best of beaches! You should visit soon!"

"Only if His Majesty takes a holiday with me," Eve gazed at the woman with sky-blue hair, smiling.

"I would love that. We can have so much fun," Marchioness giggled just from imagining it.

Aurum turned his eyes towards the humans, "How was your trip to the human world?"

"Dangerous. The world happily sits at Phase 3," Marchioness stood up, the giggle face slowly turned serious, "if not for His Majesty's blessing, I would have lost my life."

"Phase 3...the other worlds we found don't even cross Phase 1," King Aurum maintained a solemn look for a moment before a smile appeared on his face, "That means you must have found some great Furnaces."

"Yes," Marchioness bowed to the King when one of her Knights pushed a girl forward. The young girl was Arthur's age, wearing a white sundress. She had long black hair, reddish brown eyes that nervously looked towards someone in the crowd. All the eyes in the room were on her, which made her face turn red, catching King's attention.

"Did you start the Demonification Process?"

"I did, Your Majesty."

"Your Majesty, Demonification," Eve whispered, asking.

"When we found other worlds, we couldn't bring humans since the way Demons few the world and humans do is completely different," King Aurum explained, "We didn't want what happened to last human to happen again so we went with Demonification process that slowly turns humans into demons."

"Come here," King Aurum called the girl, and she looked over her shoulder once more, walking over to the King.

She lowered her head, greeting the King. Over the months they had travelled on the ship, they heard about the King and how important it was for them to please him if they wanted to live.

"Greetings, Your Majesty."

"What is your name?" Aurum ran his eyes over her body, her curves standing out to him. Her long legs were a good sight for him and so was the small dress that showed some of her thigh and the curve of her ass.

"It's... Tifa...Lockhart," she tried to gather courage as she spoke, and he leaned back against the chair, a smile forming on his lips.

"Come here, Tifa," King reached his hand. She bit her lip, knowing she couldn't refuse. She took his hand, and he brought her close to him. Tifa didn't look him in the eyes as pulled her on the throne. She kept her knees on the throne, getting pulled into his powerful arms. He held the back of her head, strongly kissing her lips.

She stiffed for a moment before her body melted in his arms. His other hand began to stroke her long black hair. She gasped when they parted for air. She could still feel his tongue inside her mouth. Tifa sat down on his legs, and his hands reached for her breasts. She nervously moaned under King's kiss.

She looked at the villagers from the corner of her eyes, people who watched her grow, many had turned their eyes away but more than a few were staring at King's palm traced her body. The dress she was wearing had no sleeves or straps. King pulled at the strings, revealing her white lace bra that hid her breasts.

The King kissed her neck while his fingers moved under her bra, pushing them upwards. He gently kneaded her breast, pinching her nipple between two fingers. The black-haired girl arched her back against him, moaning as her breast filled his palms. His mouth moved down to her collarbone, kissing and biting it.

Tifa's breast was far bigger than other women her age. When King started to lick her areola, she felt her lower parts heat up. Her skirt had lifted, and the King's knee pressed against her panties. The man beneath her let out a dark chuckle.

"You are so obedient," he smirked as his finger pulled at the thin cloth, touching the soft flesh. Her cheeks reddened in shame when his knee parted her thighs, revealing the wetness of her panties. She gasped loudly as King pushed the thin piece of clothing inside her cunt.

Tifa bit her lip, her body twitching against his knee as her cunt squeezed around his fingers. She leaned back on the King, her eyes tightly shut as pleasure filled her body. The black-haired girl had never had something inside her, and even just one of his fingers had brought her pleasure.

King pushed her skirt higher, revealing her cunt that dripped around his fingers. His knee that kept her thighs open disappeared, and he pulled her leg around him. The dress slid between her thighs. Tifa let out a gasp as she sat on his thigh, his knee brushing against her panties.

"Please... Stop this," she breathed, "I've never done anything like this.." She couldn't finish her sentence as King pushed his knee upwards, rubbing her cunt.

"She's good. I like her," King Aurum put his arm around her waist, teasing the girl while turning his attention back the villagers. His fingers stroked her lower belly while the other played with her nipple. He had been sensing something, a rise in Demonic Aura and soon the chains started rattling.

His eyes went towards the source of the sound, towards the Knight standing behind the crowd. The knight got pushed back, and the human weaved through the crowd, his aura increasing the closer he came and he leaped forward, slamming his chained hands down, letting out a muffled roar because of the metal place around his mouth.

"Your Majesty!" Marchioness formed her stance, making the motion of a spear piercing forward as the spear of water formed in her palm but before she could connect her body slammed down, falling on the ground from the sheer increase in gravity around her.

The boy slammed his chained fists forward, crashing into an invisible wall, glaring at the King. His body got slammed back onto the ground. He rolled, jumping to his feet, tearing the metal plate from his mouth. He glared at the King, "Let her go!"

"Your...Majesty," Marchioness tried to lift her up, begging to the King, hoping he would take his pressure back and allow her to stand.

"Cloud!" Tifa worriedly shouted, hoping he would stay still. He had been different since they came to this world, to the point that Marchioness kept him in chains and his mouth shut for fear he would go out of control.

"Your boyfriend?" Aurum narrowed his eyes.

"Please, don't do anything to him!" Tifa begged, "I'll do anything!"

"Shit," Marchioness cursed under her breath. She found a few insanely talented furnaces with great difficulty, but if this girl kept talking, King would lose all interest in her, 'I taught her not to do stuff like that!'

"Tifa!" Cloud shouted. He started running forward to attack the King. Arthur wanted to interrupt him but he was stopped by Eve, who understood King's personality the best. The reason Marchioness was being punished was because she dared to assume that King had to be protected. He was the strongest existence in these lands.

Not even the Dragon King or Titan King wished to fight him. It was rare that someone was foolish enough to raise their hand at him. When it did happen, it amused him greatly, and anyone who got in the way of that...

"I SAID GET AWAY FROM HER!" the boy slammed his leg on the invisible wall, getting hurled back into the crowd.

"CLOUD!" Tifa and another shouted out his name. A blonde woman grabbed him when he tried to get up, "Stop! Please stop!!"

Aurum glanced towards the boy's leg, broken, bleeding, healing. He narrowed his eyes, "Cloud, was it?"

His voice silenced the fearful whispering of the people, and the crying of the people, "Do you want to protect them?"

Cloud looked up at the King, clenching his fist, not letting go of the strength in his heart, "I will protect them!"

"Very well," Aurum let go of Marchioness and her Knights could finally move again. He smiled, "Okay," King turned his eyes towards the nearest door, "Gareth."

A Royal Knight walked in through the door, bowing, "Your Majesty."

"Send all the people to the camp. Leave these two behind and have the boy freed from chains," Aurum waved his hand. Royal Knights walked in the room, making the humans walk towards the door. Though two people stayed in their place. Tifa's father and Cloud's mother.

King Aurum patted Tifa's back, whispering, "if you are worried about him, go."

Tifa didn't know what King was thinking, but she could tell he meant it. She got on her feet, walking faster, hugging Cloud, "Cloud!"

"Tifa," he worriedly held her, "I am sorry."

"No...no...you don't have to be sorry..." Tifa whispered.

"Don't worry. Both of them will be safe. You have my word," Aurum addressed their parents, who finally gave up following the other slaves.

Once the room was nearly empty again, "You two. Come here."

Cloud hesitated, exchanging a look with Tifa, who took his palm, walking over to the King. Though Cloud kept glaring at the man, "What?"

"Don't be so on the edge, kid," Aurum ruffled the boy's hair, chuckling, who tried to slap his hand away but failed. It was too heavy to throw off, "I am Aurum. What is your name?"

"Cloud...Cloud Strife."

"You have talent kid. From now on, stay in the Palace and train. Once you are strong enough to land a hit on me, you can take Tifa from me. Till then, she belongs to me," Aurum calmly declared, making Cloud tense up, "I won't hurt her. That much I can promise."

Cloud clenched his fist. The power inside his heart was disappearing, even when it was much higher he couldn't even break King's defence.

"I would be happy to wait," Tifa took Cloud's hand, smiling at him, encouraging him.

Cloud scratched his head, sighing, "Fine..."

"Good. We'll start your training from tomorrow. For now, go and rest. Arthur ask the maids to prepare rooms for them."

"Yes, Father," Arthur glared at Cloud, but he held back, "Come with me."

Eve breathed out in relief, seeing the two of them leave as Marchioness bowed and asked, "Your Majesty. Should I bring in the next batch?"

"Yeah. Go ahead."
