Dragon King of Apocalypse

It has been over half an hour since the devil tide. So far, they haven't met any more demons for a while, mostly from the aftermatch. That utterly changed in a few minutes as Tang Wulin nose twitch and he saw before him an enormous foot.

He looked up to see a Large being that was tall as a mountain with charcoal skin that had cracks on it with glowing orange eyes that could look down at everything.

Tang Wulin narrowed his eyes and then instantly moved as he saw the giant eyes glances at them. Before the giant could react, Tang Wulin send out a fist that roared out with the power of a dragon and with purple-blue energy that caused the air to tremble.

'Magic Devil Fist.'

The giant felt its soul and whole being tremble with fright as it saw that weird purple-black energy rounding around Wulin fist.

Bang!

The giant's foot was blown away as Tang Wulin fist made contact with it. Before the giant demon could roar out in anger, it felt something as strange energy was seeping inside its being.

Yet Tang Wulin didn't give it anytime to think as he went on for another attack. As he inhales and then roared out toward the giant.

'Magic Devil Rage.'

Purple-Blue beam of energy sped off toward the charcoal giant whose soul trembled once again from the aura of the purple-blue energy. The beam then struck the giants head and pierced through.

The whole giant body shook and then began to fall. All of this took three seconds from the moment Tang Wulin move to the moment the giant fell. While this was happening, his friends blink their eyes and were a little bit shock at how easy the demon died.

While Yuanen Yehui whole body trembled from Tang Wulin using his Devil Slayer. She felt her Fallen Seraphim shaking in instinctive fear and suppression, similar to the charcoal giant that was just killed.

Tang Wulin narrowed his eyes as he saw something invisible seeping inside his body.

'So It's similar to Dragonslayer arts. I can reap and absorbed a demon soul to get stronger.' Thought Tang Wulin.

He then delves deep into his spiritual world and began following the invisible energy as it was heading toward an area he has never been to. After a while, Tang Wulin was able to see where the energy was going to, and he was shocked at what he found.

In front of him was a being that had a similar body to his old one from Fiore but a unique type of features sitting in a lotus position. Its body was deep dark blue with purple tribal markings around it. On its face were similar markings he had before with four gilded horns growing out of its head.

The invisible energy of the charcoal demon went inside the being, and the elaborate tattoos began to glow but didn't cause the being to even twitch.

Tang Wulin furrowed his brows as he could feel that this being was still asleep. Although it was barely awakened, he could still feel an abnormal amount of power from it.

'Its almost as strong as my Dragon Form.' Thought Tang Wulin in shock.

"Not surprising considering it also has the potential similar to your Dragonslayer arts." Zeref voice rang out as he appeared next to Tang Wulin.

"This is?"

"Think of this as your dragon form or something similar to it. Just like how one can turn into a dragon from the power of the Dragonslayer arts, one can turn into a demon from the devil slayer art."Said Zeref with a significant expression.

"This Acnologia is your Etherious Form."Said Zeref causing Tang Wulin to sigh towards him.

It wasn't like he didn't know the risk of learning Devil Slayer Magic but he still didn't think his demon form would form this quickly.

"Normally you are right, as even I was surprised by this development. But I think I know why." Said Zeref causing Tang Wulin to arch a brow.

"Your Etherious form may have been sped up from your bloodline of the gods and Space Between Time power being in your body. While it didn't awaken this form at all, it did at least form the base for it." Said Zeref.

The Etherious Form must have been siphoning the powers of the Asura, Sea God, and Space Between Time to gradually form. Now it would just need the souls and energy of those with demon-like properties to fully awaken.

"This does grant you benefits though. As now your Devil Slayer power will become stronger and your resistance to powers will be better than those who normally practice this art." Said Zeref.

The power of the Devil Slayer would grant one the ability to attack on the level of the soul. Meaning the stronger Tang Wulin Devil Slayer power becomes, the more effective it would be on his enemy soul.

"With you killing the demons in this world, the time needed to train your devil slayer will also be reduced." Said Zeref causing Tang Wulin to nod his head.

Similarly to when he was slaying the dragons, he felt his Dragonslayer powers growing and becoming easier to use after each soul he absorbed.

"What about the after effect?" Questioned Tang Wulin.

"You should be fine since your mental force is at such a high level. The higher your spiritual power becomes, the easier it will be to defend against the DevilSlayer insanity and madness. But be warned that the more demons souls you absorbed, the harder it will be."Said Zeref.

Devil Slayer art carried the risk of one losing their sanity and mind. It becomes even more apparent the more demons one slay and absorbed as they start to get tainted.

Shaking his head, Tang Wulin left the area his Etherious Form was in but not before hearing Zeref last comment.

"Although I never thought I would behold an Etherious form that even surpasses E.N.D."

Blinking his eyes, Tang Wulin noted everyone monitoring the area for any more demons.

"Well, I don't see any more demons but we should go before anymore comes." Said Ye Xinglan causing them all to nod.

"The giant seems to around the level of spirit king." Said Gu Yue as her violet eyes were staring at the dead charcoal giant.

"It's at a Spirit King level."Said Yue Zhengyu as he glances at Tang Wulin.

He could tell Wulin was at a Spirit King level too but was able to crush the giant in two moves. Although it wasn't a much of a shock to him. It more of irritation as he knew it would take around ten or more moves for him to beat the giant.

"Alright, let's move on." Said Yuanen Yehui as she began to move.

They kept on moving for a while, with them encountering a variety of demons which were easily taken care of by those who saw it. Xu Xiaoyan was able to employ long-range killing with the bow she made from ice.

With the help of Gu Yue whose spiritual force was able to reach the Spirit Domain after the hell week. Tang Wulin sense of smell, Xu Xiaoyan was able to know where to launch her arrows. While Tang Wulin was already at the Spirit Domain too and was further than Gu Yue in terms of level.

He lacks the control and finesse that Gu Yue had, so it was far better for him to exercise his sense of smell to find the enemies. Tang Wulin didn't forget to absorb the demon souls after they were killed, allowing him to feel is Devil Slayer power getting stronger.

With the help of Zeref, he was able to manipulate the demon souls and energy to come towards him. Because of this, he didn't need to actually be the one to slay the demons and only need to just force the energy to come towards him.

Everything was going relatively fine until they heard a deafening explosion.

BANG!

"What the!" Exclaimed Xie Xie as he saw a huge burst of orange lightning appeared down from where they were. Gu Yue spread out her senses toward the area of the lightning, allowing her to see a battle unfolding.

There were over a hundred of the red demons they saw. Alongside them were green feathered birds whose eye shined with a blue fire and beside them were minotaurs with flaming axes in their hand.

Yet she didn't focus on these guys but the one in front of them. In front of them was a gray demon with a bulky sturdy body and piercing around its face. She could feel the aura spreading out from this demon, allowing her to know he was at least Spirit King level.

The gray demon shifted his gaze around the crowd of demons in front of it and then sighed. This angered the crowd of demons who then began launching attacks at him. Yet the gray demon didn't fear these attack but simply stomp down hard on the floor causing spider webs to form and then disappeared.

As the attacks hit, the area where the gray demon was, the area in front of the crowd of demons spark with orange electricity and then the gray demon appeared.

Bang!

With one fist, the gray demon instantly killed over half of the demons in his way. Then with a series of kicks and punch, the crowd of demons was murder with none of their blood being able to touch the gray demon.

"Is it coming over to us?" Questioned Wu Siduo after listening to Gu Yue relaying everything to them.

Gu Yue didn't say anything as she saw the gray demon wasn't moving and then it disappeared from where it was.

"He is coming." Said Gu Yue causing them all to get ready for battle.

"Interesting, I haven't witnessed your kind before." Said the Gray Demon as he appeared in front of them.

The gray demon shifted his gaze around each of the people in front of him and couldn't help but be excited about how strong their aura felt. Tang Wulin narrowed his eyes as he could feel this demon was similar to him, Wu Siduo and Ye Xinglan in terms of battle lust.

'A free level up for my Devil Slayer.' Thought Tang Wulin.

Wu Siduo instantly moved forward with a large intent to battle the gray demon. The gray demon smiled as he could feel her spirit and aura for battle rising.

"Uh, boss wouldn't be better to just gang up on this demon?" Questioned Xie Xie as he wanted to hurry up and find the seed.

"Not really, as we have to take care of the other demons." Said Tang Wulin as he could smell a small army of demons rushing toward their location.

Its seem the gray demon was being either chased or hunted down. And he doubts that small army would let them go, even if they weren't with the gray demon. Xie Xie lips twitch as he could feel the vibration of the small army of demons and only sighed.

Yet neither the gray demon or Wu Siduo put the approaching small army in their mind. As their gaze was focused on each other.

SWOOSH!

Wu Siduo instantly summons her hell civet causing ears and claws to appear on her. She instantly dashed toward the gray demon who narrowed his eyes.

With a growl, bolts of orange lightning burst from the gray demon towards Wu Siduo. Yet She didn't stop her charge as the lightning was approaching her but instead break straight through the lightning.

Bang!

The gray demon's eyes widen a little bit but nonetheless still maintained his calm as Wu Siduo was only five meters from him. He sends out a punch towards her, but she instantly split into five clones causing him to narrow his eyes.

Yet with masterful movements, the gray demon was able to block each of the clones' attacks. But that didn't even phase Wu Siduo as her cat feature instantly changed into white hair causing the gray demon to tremble. Three purple rings appeared and began to light up.

'White Tiger Vajra Transformation.'

Wu Siduo smashed her fist into the gray demon and sent him flying through the air. Then her white hair changed back into cat ears and claws. Then behind her, five and sixth black rings appeared and began to light up.

'Hell Connected Shadow.'

'Godspeed.'

'Hell Body.'

'Hell Instinct.'

The gray demon was able to stabilize himself, then he was about to counter but he then heard a large booming sound and then felt something was off. He slowly looks down to see he his head was severed from his body.

This wasn't a surprise as the power of Wu Siduo skills and their combination was too deadly. Her God Speed allowed her to increase her speed, reaction, and perception by 300%. Then Hell body increases her speed by another 100% with attack penetration, dexterity, and resistance.

Then Hell instinct grants a further 50% boost to perception, dexterity and her thought process. All these boosts stacking on each other made it practically impossible for the gray demon to react to her hell connected shadow attacks after being knockback.

Wu Siduo had the second strongest body out of the group from training in the body sect and her spirit boost made her body even stronger.

It was not wrong to say when it came to instant firepower and combat power, no one was greater at this except Tang Wulin.

The gray demon died with an expression of shock and regret. Not from his death but from being unable to use all of his power. Yet Wu Siduo didn't care as she knew Wulin would hit any of them upside of their heads if they didn't fully crush their enemy at the start.

She shifted her gaze over to the other side and saw her friends were easily cleaning up the battlefield. Feeling her blood boiling, she dashes over to go join them and in a few minutes, all of the demons were dead.
