The Flame Demon Oslu's eyes narrowed sharply, locking onto Aiden instantly. He spoke in a cold tone:
"Human, you're so stupid to use Demon's Domain against me, a demon noble!"
"Die!"
As the dark ritual circle appeared, the Flame Demon Oslu didn't run away at first. As a strong being about to become a demon count, he saw right away what skill Aiden was using.
Run?
A 10th-level human's Demon's Domain couldn't be that strong. There was no need to...
In an instant, the dark ritual circle exploded. A huge wave of dark energy rushed out like a flood, completely covering the Flame Demon Oslu's huge body.
"How is this possible? This isn't just a normal Demon's Domain!"
The Flame Demon Oslu roared in panic. He tried to escape from the Demon's Domain, but it was too late.
Vespera, the little girl Demon God's Messenger, and the Troll Warrior didn't miss this chance.
Facing a 40-level Abyss boss, they had to give their all. One mistake and they would all be wiped out.
Vespera and the others moved quickly, blocking the Flame Demon Oslu's back and both sides.
They stood very close to the Demon's Domain. The strong dark energy made Vespera's heart beat faster, and her hair stood on end.
"This powerful dark skill... was released by that handsome guy earlier. Who is he?"
Even in this life-or-death moment, Vespera couldn't stop herself. Aiden's performance was just too mysterious.
He looked about her age, and yet he was stronger than her, the daughter of the sky.
"Back up a little!" Aiden shouted, and started to pull out mana potions from his storage space, throwing them into his mouth one after another.
[Demon's Domain: Starlight Rank `- Creates an area full of death and despair. It quickly gathers dark elements and attacks everything within the area, dealing high magical and physical damage, and causing massive spirit damage to those hit. This is a domain skill, a dark skill, and it uses little mana. Increasing mana usage can expand the domain's size, up to ten times bigger.]
Using more mana made the Demon's Domain bigger and stronger.
Faced with a 40-level Flame Demon Oslu, Aiden didn't dare to relax.
At that moment, he looked like a man about to die of thirst, drinking expensive mana potions like they were nothing.
Endless mana kept the Demon's Domain hitting the Flame Demon Oslu.
His life had dropped from 5 million to 30%, leaving 1.5 million.
"Damn you, human! Do you think you can kill me like this?!"
The Flame Demon Oslu screamed in pain, and his voice shook the ground around him.
But Aiden showed no fear. Only excitement.
He had planned to finish his class change quest, take a quick look around, and then go back to The White City to submit it.
But the Flame Demon Oslu's appearance was dangerous, but also a big opportunity.
This was a 40-level Abyss boss, and it was Epic!
Iron Dragon was just a 30-level Diamond boss. The materials it dropped were already worth a fortune.
If they could kill the Flame Demon Oslu, they would get a huge amount of Epic materials.
Just thinking about it was enough to get your heart racing.
The materials from a Diamond Rank Iron Dragon had already shaken the whole The White City. Even for a short time, they couldn't be sold directly—they had to be auctioned.
And that was just for Diamond.
Epic materials from the Abyss were way more valuable than regular boss drops.
But things didn't go as smoothly as expected.
Suddenly, the Flame Demon Oslu's body exploded with red light, like fire. It kept pushing against the dark energy inside the Demon's Domain.
Some of the red light that escaped the Domain started burning the ground.
The Abyss floor was covered with bones and messy, sticky blood from all sorts of monsters. Under the heat, it gave off a terrible smell.
"Hold him back!" Aiden looked at Vespera and the others.
They were all famous geniuses in The Sovereign City. They had to have some strong tricks up their sleeves.
Compared to Iron Dragon, the Flame Demon Oslu was stronger and harder to kill.
If he could keep leveling up now, all that experience would make his level jump fast. No need to deal with this demon so hard.
At that moment, Vespera looked at the little girl and said with a determined face.
"Vivi, now!"
Vivi, the Demon God's Messenger, took a deep breath and started chanting in a strange, hard-to-understand language. Her body began to glow with black and white energy, and she flew quickly toward Vespera.
At the same time, Vivi's legs gave out, and she collapsed on the ground of the Abyss.
"Demi-God Boost!"
She had used a powerful skill, and it had drained her completely. She couldn't fight anymore.
Now, Vespera transformed into a dragon form. Her golden scales glowed brighter after absorbing the black and white energy.
Her huge dragon wings flapped, leaving faint golden afterimages.
With the Demi-God Boost, Vespera didn't hesitate. She grabbed her sword and ran toward Oslu, who had just reached the edge of the Demon's Domain.
"Dragon Roar Sword!"
Her sword suddenly glowed with a bright golden light, like a giant dragon's shadow. It roared forward and struck at Oslu.
The Flame Demon Oslu quickly raised his ugly demon claws to block Vespera's strongest attack.
"Roar!"
"Boom!"
The dragon shadow roared, and the impact sent Vespera flying backward through the air.
Her beautiful face turned pale, and she spat out a big mouthful of blood before landing heavily at Aiden's feet.
The Flame Demon Oslu wasn't doing any better. His arm looked like it had been torn apart by a dragon, and his bones were now visible. His health had dropped to 10%.
But Vespera wasn't happy. That last attack was all she had left.
And still, she hadn't killed the Flame Demon Oslu!
No wonder he was almost a noble of the Abyss.
"We're done for," Vespera bit her lip and pushed herself up, looking up at Aiden.
"Run now. If you leave the battlefield and make sure the area is safe, you can just go back and leave the Abyss."
She was badly hurt, and Vivi couldn't fight anymore. The only one left was John, the Troll Warrior.
But the Troll Warrior was strong in close combat, and weak when it came to running away.
The Flame Demon Oslu, with only 10% health left, slowly broke free from the Demon's Domain.
Aiden took a deep breath and canceled the Demon's Domain. He started drinking mana potions even faster.
"Ten seconds!"
Aiden said quickly. His face showed no fear at all.
This demon had only 15% health left. Giving up now would be too painful.
Vespera blinked. Ten seconds?
Was this boy, about her age, hiding something strong?
"John!" Vespera chose to trust Aiden.
The Troll Warrior John closed his eyes, then opened them again.
His normal eyes turned red, full of rage.
"Frenzy Blood!"
John screamed and his muscles swelled. He was already 1.8 meters tall, but now he grew to over two meters, like a small giant. He stood directly in front of the Flame Demon Oslu, blocking his path.
The Troll Warrior skill, Frenzy Blood, could push his power to the limit—but with serious side effects.
"Weak human. Die!" The Flame Demon Oslu only saw Aiden.
If it wasn't for him, those weak humans would already be in his stomach!
"Ten seconds? Even if i gave you an hour, could you kill me?"
The Flame Demon Oslu clenched his fist. A wild fire wrapped around his giant fist and smashed into John.
The level gap was too big. John had no chance.
The three geniuses from The Sovereign City had all lost their fighting power and were now lying on the ground, watching Aiden.
Aiden exhaled lightly, looking at the approaching Flame Demon Oslu. He smiled.
