Dragon King of Apocalypse

In a private hallway, a person was running through the passages, while looking out for any traps that may have around. As he was running, he felt a sharp pulse pass through his body and then he narrowed his eyes.

"I see, so Yuanen demonic form must have gone off." Said Tang Wulin

"It did." Said Zeref with his expression changing.

"Yea, it did."

Before him and his friends venture into the demon world. Tang Wulin made sure to pour and store some of his devil slayer magic into Yuanen, from Zeref suggesting it as an extra measure. The energy stored inside wasn't meant to destroy her demon form but to help give her a chance to fight it.

"Are you sure you did the right thing, to not suppress the demon energy inside of her?" Questioned Zeref to Tang Wulin.

"You know better than anyone, that suppressing it wouldn't help her growth in the long run. Right now she needs to learn to not only dominate that power on her own but accept it as her own."Said Tang Wulin.

Zeref only let out a sigh but in the end, he did agree with Acnologia.

'Is this how you came to accept your Dragon and Etherious form so easily?' Thought Zeref as he glances at Tang Wulin but said nothing.

Tang Wulin still picks up the pace through the hallway.

"Y-You! How could you!"Roared out her mothers-look alike.

Yuanen Yehui uttered nothing as she gripped the two black swords in her hands and began to dashing toward her. Her mother-look alike saw Yuanen coming and roared, sending a huge shockwave reverberating through the realm.

Yuanen Yehui quickly moved her swords in front of her as the shockwave hits and sent her flying through the air. She was able to regain control and landed on the ground without much damage while also able to see what was happening in front of her.

Her mother-look alike was swelling all over like a balloon with her figure becoming bloated and then she burst open with purple-gold blood landing all around. Yuanen Yehui eyes widen when she saw the towering figure emerging from within.

It was towering figure made out of purple-gold flames with two towering wings behind it and two deep purple eyes that were locking on to her figure.

"To think, you were able to fi-."

Before the towering figure could finish his words, a black sword was hurled into his forehead and caused a pool of purple blood to flow down.

Yuanen Yehui didn't care for what the towering figure wanted to say, as she dashed toward him while summoning another black sword. The demon figure roared out and smashed down causing a wave of purple-gold flames to travel towards Yuanen Yehui.

Yuanen Yehui said nothing as she leaped over the flames that were coming towards her and continued moving towards the demon. The demon roared out as a purple-gold sword appeared in its hand and then hack down towards Yuanen Yehui.

She side-steps the attack and used the outstretched arm as a launchpad. She ignored the flames that were stinging her and propelled herself toward the demon. The demon swung its other arms toward Yuanen Yehui, but she only twists her body to dodge the arm and began running down on the arm.

"You!"

"Shut up." Said Yuanen Yehui as she launches herself off the demon arm and toward his head. The demon eyes widen as two black swords were lodged into his forehead, right next to the other black sword.

Yuanen Yehui expected the demon to roar out in pain or defiance but instead, it only grins. Her eyes widen and as she was about to kick off from the demon, it was already too late.

The demon form dissolved into a sphere that began to wrap around Yuanen Yehui. She tried to fight her way out but it was useless as her body was fully absorbed into the sphere.

Yuanen Yehui blinked her eyes and found herself in a world filled with purple-gold flames. As she was glancing around a figure began to appear as a pillar of flame rose up in front of Yuanen Yehui.

"Look what we have here."Said the demon with a grin as his figure began to fully form and his two large hands were holding Yuanen Yehui.

"You planned this."Said Yuanen Yehui causing the demon to chuckle.

After seeing how its plan of using the visage of Yuanen Yehui mother wasn't working, the demon decided to try something else. He came up with the plan to directly corrupt her and force her into endless sleep, so she may never interfere.

So he planned to capture her when she came up close to him. But hee made it look like he was trying to keep her away, so she didn't get suspicious. Who would have thought it would work so perfectly and with no mistakes involved.

'Now that I think about it. Isn't this a bit too easy?' Thought the demon while holding Yuanen Yehui.

'In fact, she didn't use her other skills but her two black swords.' Thought the demon as he started thinking more about the fight he had with Yuanen Yehui.

But he didn't have enough time to think about the fight as he heard Yuanen Yehui next words, that caused him to tremble.

"I didn't expect this to work. Now that I'm close to you, it's about time I take what's mine."Said Yuanen Yehui with a light flashing through her eyes.

"What are you talking about!" Roared out the demon but Yuanen Yehui said nothing as a massive amount of spirit energy began to burst forth from her and destroying hands that were holding her.

"What are you doing!"

Yuanen Yehui grabs on to the arms of the demon.

"Nothing much, just absorbing you."Said Yuanen Yehui with a smirk and then she began to draw the power of the demon inside into her.

Since the demon seed inside of her wanted to absorb her, then there is no reason she couldn't do the same. In the end, the seed was apart of her whether she likes it or not and it's about time she takes command of it.

'Since you have been inside me for such a long time, I should take responsibility and put you under control.'

It was her power that destroyed the Pavilion in Tenrou City and harmed her friends. So it is her responsibility to control it and make sure something like that will never happen again. Yuanen could feel all of the cloud and mist that has been forming around her heart was being blown away as she finally realizes what to do.

'Its time to bring you under control.' Thought Yuanen Yehui as she began absorbing the purple-gold energy.

"Stop!" Roared out the demon but Yuanen Yehui simply disregarded it as she sped up the absorption rate.

"You can't fight back can you?" Questioned Yuanen Yehui but the demon only wails louder.

"Of course you can't. Because you are nothing before your true master."Said Yuanen Yehui.

"Y-You aren't my ma-."

"Of course I'm." Said Yuanen Yehui as a tall figure began appearing behind her with six feathered wings expanding out, this was her Fallen Seraphim.

The Fallen Seraphim thrust out its two hands toward the demon and similar to Yuanen Yehui, it began absorbing the purple-gold flames. The demon continued wailing out loud, but Yuanen ignored it all.

"Its time to come home."

Bang!

Xie Xie duck under a swipe of the black sword that almost bisected him. Then he raised his Dragon Space and Time dagger to block the black sword hacking down on him.

As they struggle against each other, the wielder of the black sword body started to tremble and with a loud shriek, began to fall.

"Yuanen!" Shouted Xie Xie as he dashes toward Yaunen Yehui and caught her.

After he had caught her, he began looking over her condition and to his surprise, he saw all of the demonic features fading away. Even though he had no idea what was happening, he at least knew that Yuanen was alright.

'That was a close one.' Thought Xie Xie with a sigh as he knew he was struggling just defending against Yuanen. Her strength was far stronger than before and with the person in control being able to utilize more of Yuanen soul skills.

While he was thinking this, he felt movements coming from his arm and glance down to see Yuanen moving her body, before she opened her eyes.

"...Xie Xie."Mutter Yuanen Yehui.

"Yuanen." Said Xie Xie with a chuckle and a smile.

Yuanen Yehui didn't say anything as she glances around while noting the slash marks on Xie Xie body and the damaged around the arena. Xie Xie felt his shoulder being gripped as he saw Yuanen furrowing her brows before opening her mouth to speak.

"It's okay." Said Xie Xie with a grin on his face.

Yuanen Yehui eyes widen and then she let out a small smile.

'You idiot.' Thought Yuanen Yehui with a shake of her head. She began getting up with Xie Xie helping her up.

It was then they heard a large number of footsteps coming behind them. Xie Xie and Yuanen Yehui turn around to see their friends running toward them. No words were said, as they all crashed into each other and words were exchanged.

"You saw your dead mother?" Questioned Xie Xie.

"Mhm."

"You had to fight had a purple-gold towering demon." Questioned Xu Lizhi with his eyes widening.

"Yes."

"Wait, so you absorbed your demon powers?" Questioned Xu Xiaoyan in shock.

"Yes." Said Yuanen Yehui with a laugh.

Tang Wulin shook his head at them questioning Yuanen about what happened. As they were doing that he turned his head to the demon seed that was laying down from them or what was left of it.

Half of it was destroyed, with the rest of it starting to fade away.

"I guess the mission is accomplished?" Said Zeref as he appeared next to Tang Wulin.

"I-."

Before Tang Wulin could finish what he was saying, the demon seed began to tremble while giving off chaotic energy. This caused everyone but Tang Wulin to turn their heads in surprise and shock.

"Isn't that the demon seed!"

"Why is it acting up!"

"I know it was half destroyed by the time we got here!"

The space around the seed began twisting as the chaotic energy increased. It was then the group of humans saw the seed let out a beam of light towards the sky.

The sky was instantly split open as a surge of power reverberate through the room from the opening and then a figure came down.

The ground shook.

"Quickly!" Shouted Tang Wulin as he instantly summed his Blue Silver Genesis and use his time magic to create an array of vines in front of everyone.

A surge of oppressive flames was unleashed with the intent to eradicate everything in heaven and earth. It was even more terrifying as it began to engulf everything. The flames washed over the ground like tidal waves, sweeping through the earth like a hurricane.

The ground was incinerated and scorched turning blacken that won't be able to heal for centuries.

Purple-gold sea of flames was uprooting everything in the arena. The flames burned brilliantly like the raging sun as it began to descend towards Tang Wulin and his group of friends.

"Ultimate Fire!"

"Absolute Lunar!"

Were the cries of Tang Wulin friends as they unleashed their attacks to defend against the tsunami of purple-gold flames rushing towards them. Golden Flames and flowing ice went towards the purple-gold flames, but they only held it for a few seconds before it overpowered them.

Everyone else attacks were instantly overpowered but it was able to weaken the sea of flames charging towards them. As it made contact with the multi-colored vines, it caused the vines to tremble and shake but the vines still held on.

It didn't take long for the sea of flames to die down, and what awaited the group of humans was a land of flowing fire. The fire was moving through the cracks of the ground, and some puddle of the purple-gold flame remains.

"Vermins..." A voice rang out to them.

They all turned their head and saw a demon covered with purple-gold scales with two massive wings held high behind it. Yet the most important thing was the half-broken seed that was stuck in its chest.

The demon with just one drop was able to produce an attack that could overturn battlefields and take on a whole army. The power that was at the limits of the mortal realm, a power that could easily wipe out an army as well as reshaping the whole landscape.

"You all should be praising yourself."

"For surviving a casual attack from me."
