Veins began swelling around Tang Wulin's neck as he continued absorbing the destruction energy inside of his mouth.
To say it hurt like hell would be an understatement, as Tang Wulin could feel his mind and consciousness swaying. Although it wasn't as bad as breaking the dragon seals or going through the Spirit Metamorphosis.
"Damn it." Said Sleipnir with her eyes filled with concern.
She wasn't the only one as the people behind Tang Wulin was too shocked and frightened to react as they saw him still swallowing.
Strangely enough, it was only Zeref who wasn't showing any signs of shock as his expression was blank as he stared at Tang Wulin. Sleipnir didn't notice this as she was too worried about Tang Wulin at the present moment.
Tang Wulin began clenching his fist and close his mouth as he began to absorb the last of the destruction energy coming towards him. Sweat was beginning to form on his head, as he could feel the destruction energy running amok.
Yet, the only reason he didn't get disintegrated or destroyed was because of his body. The dragon-like body that allowed him to use the Golden Dragon King power of ruin. Of course, the energy didn't continue running amok as he could feel something deep inside of him trembling.
It was next, a pulsing power reverberates through Tang Wulin's body as the destruction energy was rampaging forward. It was then energy swept through his whole body and began dissipating the destruction energy into nothing.
After that, Tang Wulin could feel his strength was returning, and his energy is restored. The only thing that remained the same was the fatigue of absorbing the destruction energy for the first time.
"...You actually did it."Said Sleipnir in shock as she saw Tang Wulin gradually regaining his breath. While Zeref and Tang Wulin did explain to her about the characteristic of the Slayer Arts, with her seeing it in action countless amount of time.
She didn't actually believe it could even eat primal powers like the Destruction Energy! Gods with a God Position are beings who each govern a power or law on a fundamental level.
For example, if one was known as the God of Water, it wouldn't just mean they can control the water in all of its forms. Oh no, it means they embody the specific idea of water itself, on a level that goes all the way down to the origin of Heaven and Earth.
This was why True Gods are known as the 'strongest existence' in the universe. As their control over their specific position is something unmatch and untouched by any other's.
Not only that but this was the God of Destruction! He was one of the God-Kings and Enforcers of the God Realm! Even if the energy around them represents only a bit of his strength, it was still the energy of a God-King that embodies the fundamental Principle of Ruin and Destruction!
The normal scenario for the ones who came in contact with this type of energy who isn't a god or strong enough would them being disintegrated. Along with their soul, mind, and body being destroyed on a level where they couldn't reincarnate even if they wanted to.
Yet Tang Wulin was able to eat this primal power and not be destroyed by it.
'He actually did it...' Thought Zeref with a bit of shock. While Acnologia version of the Slayer Art essentially allows him to eat or absorb any type of power. Zeref wasn't a hundred percent or even half sure that Acnologia would be able to eat a power like the Destruction Energy.
Of course, he and Acnologia already made safety plans just in case he couldn't. As the energies in his soul core, blood core, slayer arts, and even his Annihilation will move out. They would destroy the destructive energies before it can do any real damage.
Since those powers were like a passive force that destroys anything harmful that invades his body. Heck, even his Light Wings would activate to help him out if it got too dangerous because of the influence of the Asura Blood.
'That wasn't so bad.' Thought Tang Wulin with a sigh while ignoring the reactions of the people behind him.
"Let's continue." Said Tang Wulin as he continues charging forward causing everyone to blink their eyes before sighing.
'Big brother can't you be normal for one moment.' Thought Xu Lizhi as he tried calming himself down from what he just saw. It wasn't only him but Wu Zhankong and Shen Yi were trying their best to return to normal.
Either way because of Tang Wulin's actions, they didn't feel any pressure or terrifying energy anymore and continued on forward.
It was then they found themselves in a different area after passing through some type of barrier or shield. They all blink their eyes as they saw a huge mountain valley fill with luxuriant green plants and an abundant amount of origin energy around.
"It's close." Said Sleipnir as she could feel a dense amount of life energy down from where Tang Wulin was.
Yet Tang Wulin was staring towards the elderly being down from them. He wasn't the only one as Wu Zhankong and Shen Yi too had already noticed the man. Both of them had their guards up as their spiritual senses were warning them for some reason.
Xu Lizhi noticed him a bit later but he too brought up his guard. As he still recalled his big brother training and how he shouldn't trust any stranger so easily. The old man in front of them smiled a bit before walking towards them in a leisurely manner.
"You all were able to make it inside?" Said the elderly man but there seems to be no hint of surprise in his tone.
"Are you the old demons?" Questioned Shen Yi with her guard still up.
"Oh? You have heard about us?"Questioned the old man as he got closer.
"We were given a mission from Shrek for a purpose, other than what your use to." Said Shen Yi while avoiding the old man question.
"Oh really." Said the old man, not minding the fact that Shen Yi didn't answer his question.
"Why d-."
Before the old man could finish his sentence, a hand latch on to his throat with an iron grip.
"Is there a problem young man?" Questioned the old man with a bored tone as if he wasn't scared that his neck was being held.
Tang Wulin said nothing as he slowly began rotating his palm, causing terrifying purple-blue energy to explode out of his body and demonic roar to echo out.
This caused the old man face to change as his whole body started to tremble and utter fright began manifesting onto his face. Yet Tang Wulin wasn't done as the aura started to slowly come down and began focusing on the old demon in his hand.
The old demon went from trembling to shaking uncontrollably as his body began to spaz out and within seconds he started letting out a hysterical scream. Tang Wulin ignored the scream that was echoing through the forest and began to open his mouth.
He began inhaling.
The old man figure began to twitch as a wisp of him began slowly swirling into Tang Wulin mouth. This caused Xu Lizhi and Shen Yi's eyes to widen, while their mouths were left hanging open.
Wu Zhankong faired better with his eyes only narrowed but he still kept his calm. As for the old man, he began shouting out towards Tang Wulin while begging him to stop.
"Will you behave?" Questioned Tang Wulin, as he stops inhaling to speak to the old man.
"Young man you re-"
Tang Wulin began inhaling in again, causing the old man to shriek in terror and pain as he began screaming he will behave.
Tang Wulin stop inhaling as he stared at the old man in front of him. The old man was trembling and was nor a little shorter and with his face being even paler.
"Wulin?" Questioned Wu Zhankong.
"The old man in front of us his a cursed soul, that was just using his powers to make it look like he has a body. Just now I was slowly torturing his soul and then slowly absorbing."Said Tang Wulin causing everyone's lips to twitch at the absurdity of his words.
Yet they didn't question his abilities to torture or absorb a person's soul, as there would be too many questions at the moment.
"It's okay, his existence his a benefit to Shrek." Said Wu Zhankong as he motions for Xu Lizhi to unsummoned his martial soul.
"What do you mean?" Questioned Tang Wulin with a raised brow.
But before Wu Zhankong could say anything, the ground started to tremble a bit.
Xu Lizh narrowed his eyes while he had his martial spirit outs. Only Wu Zhankong and Shen Yi didn't move as they knew that the other six were coming.
It was then six large shadows erupted from in front of them. Xu Lizhi's eyes slightly widen in surprise but Tang Wulin's expression didn't change as he merely glances at all of them.
"So they were exposed to the destruction energy which destroyed their bodies and would have destroyed their soul. But it seems the life energy must have saved them."Said Sleipnir as appeared next to Tang Wulin, while gazing at the beings in front with sympathy.
"How sad." Said Zeref as he appeared beside them too.
Tang Wulin didn't say anything as he saw the other beings behind the old man in his hand, coming towards them. He let out a bit of his Devil Slayer aura alongside a bone-chilling murderous aura that swept through the whole area in front of him.
A fierce and intimating aura of suppression flew towards the figure, causing them to flinch with some of them shivering involuntarily in fright.
The message was clear to them, 'Try anything and he will reap them'. Wu Zhankong used this chance to ask the beings in front of them some questions.
"Seniors," Said Wu Zhankong at the approaching figures causing Xu Lizhi's eyes to widen in surprise and shock.
The huge old man in front of them glances at Tang Wulin and the old man he was holding. There was a hint of shock and fear in his eyes before sighing.
"We're not your enemies. As I'm sure you all were sent here for a specific reason."Said the huge old man towards Tang Wulin.
"You are right, but I'm sure it's not what you guys think. We were sent here for a retrieval mission."Said Wu Zhankong causing the huge old man to blink his eyes.
"You guys aren't here for the Military Training!" Shouted the figure beside the old man in surprise.
"No." Said Wu Zhankong as he was already starting to have an idea of what was going on.
"Can you let me go now! We have a history with Shrek."Shouted the old man in Tang Wulin grip but he ignored him.
"Did the destruction energy do that to you guys?" Questioned Tang Wulin as he wanted to get the conversation going and over with.
"How did y-"
"...Yes." Said the huge old man, interrupting the old man in Tang Wulin grip. The huge old man sighs a bit before beginning to explain to Tang Wulin and Xu Lizhi about who they are.
Similar to what Yun Ming explained to him, Demon Island was an Island that was found over six thousand years ago.
'That asshole didn't explain how it was found or who lived in it.' Thought Tang Wulin in annoyance as he stared at the demons in front of him.
The people who found this island were soul masters from Shrek Academy, thousands of years ago. They weren't just any ordinary Shrek members but they were also the Shrek Seven Devils at the time.
These Seven Devils founded this island by chance and through exploring the island, they were able to find a fragmented crystal that seemed to hold unlimited energy. The seven devils at the time thought they found a treasure that could help Shrek. Sadly, what they didn't know was that fragment held inside of it destruction energy.
The fragment of destruction energy was in its dormant state, so it didn't erupt when they found it at first. But after they tried to take it away.
The crystal exploded outward and caused all of their bodies to disintegrate.
It was only through the life energy on the Island, that they were able to not be fully destroyed. But alas, the life energy couldn't fully save them and could only turn them into ghosts. This means If they leave the island, they will die without a host.
In the end, they could only stay on this Island and train the students that Shrek Academy deiced to send. Through the years, they became known as Old Demon Greed, Demon Sloth, Demon Devour, Demon Lust, Demon Blight, Demon Loathe and Demon Nightmare.
"To think it had such a history." Said Xu Lizhi with eyes slightly sparkling.
"Wulin can you let him go, now." Said Wu Zhankong.
Yet Tang Wulin still didn't let go of the old man, who was known as old Nightmare.
This was noted by Nightmare by himself who was feeling uneasy from the blank stare Tang Wulin was giving him. The other demons didn't know what to do, as they were unsure if they could stop Tang Wulin from absorbing Old Nightmare.
"If you all don't want to be eaten, then begone from my sight and never appear again." Said Tang Wulin causing the old demons to tremble a bit but they all nodded their heads in a hurry.
"Xu Lizhi, from now on. You aren't allowed to leave this island until you pass their training."Said Tang Wulin.
"Right." Said Xu Lizhi as he knew this was one of the reasons he came here. As his master told him she also came here to train when she was still a student at Shrek.
"I will be going on an ahead." Said Tang Wulin as he let go of the old demon Nightmare causing him to let out a sigh of relief.
Then he instantly got out of Tang Wulin way, as he started to see him walking. Tang Wulin was heading towards the area with the most abundant life energy.
"You don't need one of them to guide you?" Questioned Shen Yi as she glances at the spot where the old demons were.
"Nope." Said Tang Wulin as he already had Sleipnir directing him.
The old demons all let out of a sigh of relief, as they weren't sure if they could keep their life if they went with Tang Wulin.
