Four heavenly Kings, Dark Tesseract.

'How can i use Demonic Aura as sword energy?'

It is hard? For Kim Woo, it's hard. He's still growing, his knowledge about Aura's is still few.

If that's the case, he can't use 'Despaired Vampire' for now.

Yapp and Zapp was so furious. Their twin Happ just got killed by a mere human with just one pierce in chest. They gritted their teeth until it crack.

"You killed our brother!"

"This is Unforgivable!"

The two immediately ran towards Kim Woo. They didn't care about the other hunters earlier. Their eyes was just focus on Kim Woo.

Meanwhile, Kim Woo was smiling. His frustration about using Demonic aura as sword energy fade out. Right now, he needs to focus.

'Should i use pierce again?'

Earlier, he killed a Vampire by just one pierce. Now, he is confident enough to assume his victory again. But there is one thing that Kim Woo doesn't know.

"...!!"

It was so fast, so different. Yapp and Zapp was completely different on Happ, their skill, moves, plus they've teamwork.

"Ugh!"

Kim Woo was hit by the claws of the two in chest. Now he's like he fought a bear in the forest.

"That can leave scars you idiots."

The two leap 5 meters away from Kim Woo. In their point of view, Kim Woo was standing while one knee was bend, Left arm was completely down, his chest was bleeding, splurting blood. Kim Woo was completely bursted. His heavy gasp can be heard.

"Hah... Ha.."

Yapp and Zapp licked their claws as Kim Woo's blood dripped.

"Delicious!"

"But we're gonna kill you."

Kim Woo's holding his chest with his injured left arm, his right arm was defending himself with his sword.

'Ha.. Come.' What was he thinking? He is completely bloody injured, and still waiting for them to charge him.

Yapp and Zapp pointed their claws straight to Kim Woo's chest. They wanted Kim Woo feel what he did to their brother. They charged Kim Woo again and then.

"Aura Emerge." Kim Woo's strongest skill.

The two who's charging Kim Woo felt their body heavy. They been force to kneel in front of Kim Woo, it was ashamed.

"What is this?!"

"So heavy!"

Kim Woo grinned.

Thump, Thump.

The two was gritting their teeth. They can feel their burden body, still don't know what's the cause.

"I didn't expect Vampires are these weak."

He mocked them, making their pride down. It was ashamed for their Kin. They're the second strongest species and now, they're kneeling in front of human.

Kuwickkshh!

The head of two was rolling on the ground. Blood splurted, Kim Woo's mask was stained by blood, his blood and their blood.

"Soul Absorption."

[ You've absorbed the soul of the second strongest species, Vampire.]

[Soul You've absorbed: 42/50.]

'What will happen if i absorb 50 souls?'

He was wondering, curious and excited. He even forgot that he's bloody injured.

'I don't wanna consume one soul to regenerate my health.'

He's saving the soul like saving his money back then. He is too excited about something if he reach 50 soul.

"Oyy! You idiots. Does anyone of you have healing ability?"

"Me!"

John's subordinates raised its hand. They ran toward Kim Woo.

***

At hell.

"My Lord."

A Demon Knight kneeled down at the Demon Lord.

"One of my trusted soldier told me."

"What is it?"

"It's about Oyga, my Lord."

The Demon Lord frowned.

"I see. Tell this to the Four Heavenly Kings."

The Knight stood up.

The Demon Lord was sitting on his throne, it was so dark. His face can't even seen, only his eyes. "Grow, Kim Woo."

***

The Four Heavenly Kings. Well known as the Marshal of Hell. They're the strongest after the Demon Lord.

"Lord of the Wind. The Demon Lord wants you to kno...."

"Yes. I know."

One of the Heavenly Kings, Lord of the Wind, Solpho. Interfered the Knight's speech.

"Then, i'll be going."

The knights stood from his knee.

***

four man standing in front of the Demon Lord.

It was the Four Heavenly Kings. They've been summoned by the Demon Lord.

Lord of the Wind, Solpho.

4th Marshal of hell.

Lord of the Fire, Sal. The only Women among the three Marshal

3rd Marshal of hell.

Lord of the Spirit, Demio.

2nd Marshal of hell.

and

Lord of the Undead. Yash

1st Marshal of Hell. Well known as the strongest Marshal.

"I think y'all know that Oyga is making a move." The Demon Lord spoke up.

(Demio)"Yes, my Lord."

(Sal)"Don't worry my Lord. We the Four Heavenly Kings, will protect every Demonkin, not only here, but also every Kingdom here in hell."

(Solpho)"King Crit should be know about this."

(Yash)"King Crit is dumb."

Yash took the attention of the three. Why though?

(Yash)"King Crit was mistaken all over his life."

Solpho, Sal and Demio was baffled.

(Solpho)"What do you mean?",

Yash smirked. As the strongest Marshal of hell, can control a dead creatures that been suffering in hell. He is full of information.

(Yash)"It is not King Crit, the one who's cursed."

(Sal)"Huh?"

Yash looked up.

(Yash)"It is the whole world."

The Whole world not only the Ritozide Kingdom, and Hell. Should the Four Heavenly Kings worry about this?

(Demio)"Then should we worry about this?"

(Yash)"Of course. The fact that he cursed the whole world, he can be our strongest enemy."

"...!!!!"

The ground shook so hard, it was like a magnitude 10 earthquake on earth.

(Solpho)"What's happening?"

This isn't a danger for them, they've experience a dangerous enemy so far so earthquake (Hellquake) is just normal. But this is Hell, how can an earthquake affect the hell?

"Tesseract." The Demon Lord and Yash said it at the same time. But what was the tesseract?

(Demio)"So there's a Demonkin in earth huh."

Tesseract is the source of power of a Demonkin. Only the chosen Demonkin can absorbed the tremendous power inside of it. Tesseract is the reason, why the Four Heavenly Kings was powerful. They've absorbed the tremendous power of it.

(Sal)"A tesseract that made the hell shook huh."

This is the first time that a tesseract shook the hell. This means that it's the most powerful tesseract among the past tesseract

The Demon Lord smirked. "Hmm.. Then we don't have to worry at all."

(Yash)"Let's wait for the upcoming Marshal.

The Demon Lord was delighted, thinking that a tesseract shook the hell, plus it came from earth. It is obviously 'Quickly, Grow, Kim Woo.'

(BREAKING NEWS: A tremendous earthquake occurred!)

Kim Woo just arrived home. "Hey mom! You ok?"

Kimchae, Chae and JinHee was sitting at the sofa. They're watching the news just like they didn't feel the earthquake. "Kim Woo. Where were you?"

Kim Woo bitterly smile. He swallowed his saliva as he saw his mother and sister furiously smiling. "Ah... Oh by the way mom, did you see it hehe. The video where i ripped the giant hehe."

Kimchae slowly approaching Kim Woo with her clenched fist.

"Don't change the topic!"

And then he got scolded. Kimchae was pinching his ears, then.

(A Black tesseract appeared at the bottom of mountain?)

A video of a man exploring around the forest was showed. The man saw a black cube with a cube inside, tesseract. He approached the tesseract and tried to touched, no. The man tried to take the tesseract but.

("Arghh!")

The man suddenly stepped away on it.

("Its absorbing my mana! Arghhh.)

The man crawl away from the tesseract, his mana was fully absorbed. It made the man exhausted.

The mana of the man was already drained by just raising his hand to touch it, what if the man actually touch it?

The Hyun's family, including JinHee. Watched the man's point of view.

"What is that?"

Chae spoke.

"It ishh like immm the movie. Nom nom."

Kim Woo spoke while he have a food on his mouth. He's very starving.

"What, movie?"

Chae asked.

"Yes. Avengers!"

"...."

Chae didn't know about it, she doesn't often watch movie.

"So that tesseract is containing a some kind of power?"

It was JinHee.

"Hoo. JinHee, did you watched that movie? I really love that movie."

JinHee's body shook.

"Yeah."

"So we have the same taste ha ha."

JinHee was blushing. She just accidentally watched it because it took her attention.

Kim Woo sneak to his room while his mom's watching the news.

"Hoo."

He took his jacket of, his mask stained with blood, luckily, Kimchae's attention was on scolding Kim Woo. So she didn't see the mask with blood.

"Ahh. Those Vampires."

He looks at the scars on his that the vampires gave. it was an X. A three finger claws of Yapp /// and the three finger claws of Zapp

\\\.

"It's not look cool, Kim Woo."

He speak to himself. He was thinking about the movie where the actors have scars their chest. "Well..... It's f*cking frustrating!"

Imagine taking care of your skin all over this years just to scarred by a vampires.

'By the way. What's with that tesseract?'

***

At Hunters Association.

Kyun Toe. He is the in charge on strange loot, items.

"Tesseract huh."

He was thinking of having it, but impossible. Only a Demonkin can absorbed its tremendous power. No, it can only be absorbed by a chosen Demonkin.

"This is the first time that a strange thing appeared on earth."

Kyun didn't know any information about the tesseract, having it is the only thing on his mind. "Then i'll be taking it." A dark smile appeared at his face.

***

At Ritozide Kingdom.

Yigdra was walking fast towards King Crit.

"Your Majesty. A tesseract appeared on earth."

Nadaia was standing next to King Crit's throne.

"And I believe that it's the cause why the ground shook.

"So only the chosen Demonkin can absorbed its tremendous power right?"

"Yes."

"Then why'd it appeared above?(Earth)

"Because the chosen one is in above."

Yigdra smiled.

"You mean th...."

"Yes."

The news made King Crit delighted again.

"The person who'll lift your curse will growing so powerful."

"Powerful? You mean along with the Four Heavenly Kings?"

"No. Powerful than the Four Heavenly Kings."

It's the fact.

"So its powerful than the other tesseract?"

"Yes. Most powerful, not only the past, but the upcoming tesseract."

***

"Aura control huh?"

Kim Woo was lying on his bed while wondering how can he control his aura.

"Yes. i often use Aura emerge, but that is different."

He stood up and close his eyes.

"Ok then. Let's try."

He grabbed his sword at the inventory and start.

'Aura control, Aura Control.'

His eyes was closed as his Aura was slowly gathering at his main Aura core. Usually, Aura was scattered inside a person's body.

He can feel the Aura like a wave at his heart.

"....!! Cough!"

What was it? His Aura core was small. The Aura was too much to fit on it.

"Try again!"

It seems that gathering the Aura was easier than expected.

He closed his eyes again, gathered the Aura on his Aura core. But this time he manage to gathered few of it. Few Demonic Aura was gathered st his Aura core, the other was left scattered at his body.

This time he only have one thing to do. That is. Flow the Aura to his sword.

He controlled his mind to flow the Demonic Aura at his Aura core to his sword.

Slowly, slowly

Flow, Flow.

Until his Demonic Aura reach his hand. Now he only need it to flow at his sword. Then

"...!!"

The Sword was covered by a Demonic Aura, a black colored aura. This time, The aura that can only feel, can br seen now. He was amazed by it.

"This is awesome!"

Now that he can use his Demonic Aura as a sword energy, how can he undo it? Kim Woo perplexedly cocked his head.

"Absorb it?"

This isn't the easy, but this isn't hard too. If he can gathered, flow his Aura. Of course he can absorb it too.
