"A thousand years ago, we captured a monster from the Demon Realm. It possessed terrifying regenerative abilities and immense magical power!
We dissected and studied it, uncovering the secrets of its body. We named it diabolos!
To gain abilities like diabolos, we experimented on many orphans. Olivia was one of them, and Aurora was another; she could also withstand diabolos cells!"
Olivia could only withstand diabolos cells.
But Aurora was different.
Through experiments, we discovered that Aurora had an extremely high compatibility with diabolos cells.
It was as if she was born to be a vessel for diabolos cells.
We increased the dosage on Aurora, turning her into a true diabolos.
However, a human body cannot fully control diabolos cells.
One day, Aurora suddenly died.
This was difficult for all of us to accept; she was originally the best experimental subject.
But not long after her death, Aurora's body transformed, eventually becoming a giant monster. She destroyed the laboratory.
She completely turned into a demon, unable to think, without purpose, frantically attacking everything she saw.
The monster she became was named Diabolos the Demon by us.
We sent Olivia into action, and she successfully severed Diabolos the Demon's right arm.
At that time, there was a group of madmen who deluded themselves into thinking they could drink the demon's blood to gain eternal life and immense power.
As a result, they became vampires, turning into bloodthirsty beasts with no intelligence.
Moreover, they also had to obey Diabolos the Demon's commands.
With Diabolos the Demon and the vampires working together, Olivia was defeated.
Finally, the Three Heroes, those who successfully adapted to diabolos cells, joined forces and defeated Diabolos the Demon.
But to our surprise, Diabolos the Demon was not dead at all.
Even though his body was sealed in various parts of the world, every part of his body remained active.
We tried to resurrect diabolos to study how she achieved immortality, but we met with resistance from Aurora; she herself was unwilling to be resurrected.
For this reason, we could only temporarily abandon studying her and began researching the bloodlines of the Three Heroes, which is Demon Possession.
Those who possess Demon Possession are destined to have diabolos cells in their bodies.
As long as we thoroughly study these controllable cells, we can fully demonize ourselves and achieve eternal life."
Upon hearing all of this, the members of Shadow Garden understood everything.
These words reminded Sino of the researcher in the Midgar Kingdom.
At that time, Sid fought against that person, and Sino heard about it from Beta afterward.
According to Beta, that person seemed to have completed his demonization, becoming an immortal.
But he was instantly killed by Sid's nuclear explosion.
"So, everything was a disaster caused by the Holy Church's greed! Those hateful people!" Zeta exclaimed.
"Take us to see Diabolos the Demon's arm!" Sino said.
Nelson's face was filled with reluctance, but he had no choice. He couldn't even connect to the Sanctuary now, and thus couldn't obtain magic power from it.
Without magic power, he was just a petty thug, even weaker than the executioner, Venom.
Beta separated from the others. She took the rest of Shadow Garden to investigate other information about the Sanctuary.
Alpha, Delta, Zeta, and Sino, the four of them, led Nelson towards the center of the Sanctuary.
Diabolos the Demon's arm was sealed there... At this moment, Aurora and Sid also arrived at the center of the Sanctuary.
"Do I just need to break these chains now?" Sid asked.
"Yes!" Aurora replied.
Sid looked at the chains and pondered for a moment.
"My sword can't cut them!"
"I'm telling you, can't you see the sword here? This is the magic sword Olivia used to cut off Diabolos the Demon's arm. It's a powerful ancient relic! This sword is perfectly capable of breaking these chains!"
Sid walked over at this moment and gripped the hilt with both hands.
He seemed to be pulling very hard, but he couldn't pull it out no matter how hard he tried. Instead, a crack appeared on the ground.
"I can't pull it out!"
At this moment, a line of text appeared on the Sword in the Stone.
Anyone who recognized it would know that it said: "Device damaged, cannot continue use." In layman's terms, any person could pull out this sword now.
"How can this be! This sword can't be pulled out!" Aurora said in surprise.
Sid was only fooling someone like Aurora, who had never wielded a sword!
"Don't push it in any further, the stone of the Sword in the Stone is about to be broken!"
At this moment, a voice came from afar.
The gate opened, and Sino and the others walked in.
"They're here. According to a normal story, the main party should have arrived!"
At this moment, Sid saw Sino.
"Is he the protagonist?" Sid thought to himself.
"Aurora, why are you here?!" Nelson shouted.
Sino kicked Nelson.
He flew out directly, crashing heavily against the wall.
"You don't have the right to bark here!"
Aurora inwardly praised Sino's actions.
She knew exactly who this bald man was; he had always been extracting the essence from her body to achieve eternal life.
"Boss! Delta didn't bark!" Delta said with a puzzled expression.
"I wasn't talking about Delta!"
"Mmm~!"
Delta obediently stood behind Sino.
At this moment, Sino came before Aurora.
"Aurora, we meet again!"
"Hello, Sino!" Aurora said, looking at Sino.
Aurora was also a girl, and as a girl, she naturally liked flowers. Outside the Sanctuary, Aurora was very happy when she first saw the sea of flowers.
When she was little, she was confined to the laboratory every day. After she truly gained freedom, the Holy Church's relentless pursuit and constant enemies left her utterly exhausted.
She loved that vast sea of flowers, and she knew very well that it was Sino's welcome gift to her.
"Hahaha! Thanks to your kick, I can connect to the Sanctuary again!" Nelson cackled.
"Come out, Olivia!"
At this moment, one Olivia after another appeared.
Alpha and the others all sensed the loss of magic power.
However, after only a few seconds, their magic power stopped draining.
Sino had instructed everyone in advance on what to do. Now, the Sanctuary couldn't drain their magic power at all.
The situation with the Sanctuary was similar to the eye of greed in the academy; both absorbed magic power and then transferred it for another person's use.
"Olivia, kill these invaders!"
Countless Olivias rushed forward!
"Delta, take care of them!"
"Understood!"
Delta immediately transformed into a beast and began slaughtering them.
These Olivias were merely puppets replicated in Olivia's likeness, and their strength was terrifyingly low.
They were not to be feared at all.
Delta could handle them easily by herself.
"Aurora! Do you wish to be freed?" Sino asked.
"Aurora nodded!"
Sino directly pulled out the sword embedded in the ground.
He then tossed it to Alpha.
"Alpha, this sword is yours!"
Sino took out his exclusive weapon.
The star sword!
"What kind of sword is this? There are no ancient characters on it, yet it contains extremely powerful energy!" Aurora exclaimed.
"This is a weapon I made myself, the star sword!"
Sino brandished the star sword.
All the chains snapped.
The wall also collapsed, and everyone saw a massive arm.
Diabolos the Demon's severed arm.
