Skeleton Lord Vregon then enveloped his long sword in a greenish aura and slashed at the undead dragon.
Meanwhile, everyone other than Abium and Rit'zyk got stunned by the sudden change.
"What the hell? Can you see the future?" Nicolaus was the first one to wake up from the shock and ask.
"I analyzed the situation and made a guess. I know Skaktak would send someone powerful to keep everything under control but didn't expect it would be another Skeleton Lord," Abium muttered solemnly and sighed.
If they had tried to escape earlier, this Skeleton Lord would've acted and killed everyone in seconds.
'His strength should be around Second-Tier Mage. He also seems to have comprehended death power.' Azolla scanned the Skeleton Lord in an instant and answered.
At that moment, a blue screen popped up in front of his eyes and showed him the Skeleton Lord's Status.
'Oh? He also have unique skills like, Death Aversion, Master Sword, Dark Ray, Killing Instinct, and Nether Aura. Each of his skills could kill me countless times. Damn it; I need to get out of this dangerous place.'
At that moment, clanging sounds reverberated as the Skeleton Lord moved at an incredible speed and attacked the Undead Dragon from all directions.
Unfortunately, Abium and others didn't have time to watch the battle.
"We-"
Before he could utter a word, a cloud of black smoke suddenly appeared on Abium's side and soon formed into a humanoid skeletal figure.
It wore a dark cloak and was holding a scythe in its hand. Its mere presence gave chills to all of the nearby Undead Skeletons.
Despite looking like a standard skeleton soldier, it had physical attributes exceeding 9!
Its unique blackish fire in those two hollows caught his attention the most.
'It also has unique death skills: Evil Gaze, Shadow Heart, Death Sense, Death Whisper, and Decay Touch. Enemy?' Abium instantly unsheathed his sword and covered the edges with an advanced sword aura.
No, this time, a greenish-red aura appeared around the edges and caused his sword to make a cracking noise a little!
"Oh? You are certainly a unique guest. Go ahead, mortal. We will join you later." That skeleton turned his white skull towards Abium and spoke calmly.
'Sh*t! Another Skeleton Lord!' Abium's face turned grim.
Before he could say anything, the skeleton turned into a cloud of smoke and disappeared from there.
Meanwhile, Abium hastily signaled others to follow after him and moved in another direction.
But at that moment, the massive Bone Dragon suddenly flapped its wings and started running in their direction while opening its enormous mouth!
'No good! It's a dragon's breath!' Abium instantly knew that Bone Dragon was not after the undead group but after them!
No, it was after the Light Dragon's Heart!
He quickly grabbed Umi, put her on his shoulder, and cast the Blink spell.
At that moment, Nicolaus activated his 'Lightning Steps' spell, grabbed Fennelis, and moved further away from where they were standing.
A second later, Abium reappeared 20 meters away from where they were standing and soon frowned.
He suddenly noticed something was amiss, looked at his left hand, and soon widened his eyes.
"The metal case!" He hurriedly looked back and noticed that it was lying on the ground!
"How?" He couldn't help but ask.
I think the high density of light elements is the root cause of this problem. Your body has no such thing, so it's easy for you to manipulate the space around you and Umi using the 'Blink' spell. But that case is an entirely different matter.'
While Abium and Azolla were discussing, the Skeleton Lord Vregon and the other skeleton named Noradax with the black scythe appeared in front of its mouth and tried to attack it.
But the Undead Dragon's red eyes suddenly flickered and released an invisible chaotic wave towards them.
It was the Chaotic Invasion spell!
Even though Vergon and Noradax were powerful figures, they suddenly felt that their thoughts became chaotic.
Instead of attacking the Undead Dragon, both of them attacked each other!
In the meantime, the ten-meter-long bone tail moved at an incredible speed and attacked them.
The next moment, Vregon and Noradax were thrown off and flew in two different directions!
The Undead Dragon turned its head toward the metal case and made a deep roar!
A second later, a five-meter radius ball of purplish flame came out of the Bone Dragon's mouth, shot forward, and soon exploded while enveloping the surrounding in purple flame.
Abium was the first to react as he cast the [Blazing Shield] spell on Nicolaus in a hurry and protected them from being devoured by the purplish flame.
But due to the difference in strength, his spell started to break at an incredible speed.
"I'll do it."
Umi spoke as she moved her hand and cast her spell on them.
"[Ice Prism]!"
The next instant, a crystalline ice prism appeared around Nicolaus and Fennelis and covered them like a protective layer.
But compared to Abium's spell, this [Ice Prism] spell resisted the purple flame and protected them!
"First-Tier Spell! When did you upgrade your spell?" He asked in shock.
He also saw another layer of Ice Prism covering him and protecting them at that moment.
On the other hand, the purplish flame spread and burned the nearby skeleton warriors to crisps.
The metallic case was also melted into lava, leaving only a head-sized white beating heart behind!
Only a few skeletons and Abium's group avoided the direct flame attack and were thrown off tens of meters away.
Abium barely managed to stand up as the Ice Prism spell also broke into pieces and shifted his gaze towards the Light Dragon's heart.
'Is there no other way to take that heart?' He asked with a stiff face.
'Teleport over there and store it in your space ring. I'll take care of the elemental fluctuation. It's the same as the 'Spiritual Scan' function.' Azolla spoke in his mind.
Without any delay, he cast the [Blink] spell again, disappeared from there, and reappeared right next to the Dragon's Heart.
The Undead Dragon also noticed his arrival and opened its mouth to breathe flame again.
Thankfully, Vregon managed to dispel the chaotic thoughts, sprinted towards the Undead Dragon at an incredible speed, and attacked it with his sword.
Simultaneously, he raised his hand and cast [Dark Ray] skill.
A second later, a dense nether ray came out of his bony fingertip, directly struck the Undead Dragon's forehead, and exploded from inside.
On the other hand, Noradax suddenly appeared next to Vregon, raised his hand, and muttered.
"Evil Gaze!"
As they were attacking the Undead Dragon, Abium quietly picked up the 'Dragon's Heart,' stored it in his space ring, and ordered Azolla to solve the elemental fluctuation problem.
Then, he turned around and started running in the other direction.
At that moment, he also sensed an elemental clash between space elements and light elements in his spatial ring. But as he sent a small amount of spirit power into his spatial ring, everything started to stabilize.
He could tell that a mysterious force was using his spirit power to maintain the space's stability and soon realized that it was Azolla's work.
He soon noticed that the Light-elemental Heart was floating inside his spatial ring without any problem and sighed in relief.
'Kid, move to a safe space. I think this Undead Dragon used this Light-elemental energy to track your location.' Azolla's words soon brought him back to his senses.
'What do you mean? Are you saying Skaktok used us as bait?' Abium narrowed his eyes in suspicion.
In truth, he had long suspected it.
'It doesn't matter. The enemy won't sense any light elemental energy now. It's better to get away from here now.' Azolla added.
'You are right.'
Abium nodded and soon saw Grurdin and a few remaining Undead Skeletons standing up and gathering near Nicolaus and Fennelis.
'Escort guards?'
He also noticed that Rit'zyk was engaging himself with Phantom Killers and decided to move on.
'It's time to escape.'
He first walked towards Nicolaus and Fennelis and signaled them to get ready.
"Let's go."
Soon, Grurdin, ten Skeletal Warriors, two Death Knights, and Abium's group moved in the northwest direction and went further away from the battlefield.
Then, they made another turn and started walking straight towards the north.
But as they were crossing a small valley, everyone heard deafening roars from the dark clouds and soon saw two more Undead Dragons and tens of Wyrms flying up in the sky!
They were all moving towards the direction where the two Skeleton Lords were battling the Undead Dragon!
Grurdin was the first to wake up from the shock and yelled,
"Oh no!"
"Let's go. We should at least do our work." Abium spoke in a solemn tone and signaled everyone to move forward.
Unfortunately, every skeleton started to feel restless.
Gradually, the dark sun began to descend, and the dark ball of fire began to turn orange and almost tangerine. It merged with the sky, like a juice mix dissolving in a glass of water.
Abium also saw a scarlet moon slowly rising in the western sky and hanging like an ominous gem on the tower of hell.
Within minutes, darkness shrouded the surroundings from all directions and painted everything in blood red.
It gave off a creepy feeling.
'That crazy goddess!' He now understood why even the Ancient Mage got terrified to utter her name.
While walking, Abium suddenly felt that everything around him began to slow down and freeze. He tried to look around but couldn't.
What shocked him most was that Nicolaus and others suddenly stopped moving and looked like frozen statues!
'What happened? Azolla?' He shouted in his mind, but no reply came.
While he was confused, he noticed that the surroundings started to break like broken mirrors and replaced everything with a completely different scene.
Abium slowly opened his eyes and soon noticed that he was standing in front of a giant black tree!
The Giant Tree resembled a creepy tree made of bones, with bones and skulls growing everywhere instead of branches and leaves. Its trunk resembled a colossal giant and appeared more than 1000 meters tall, dominating the sky!
Abium instantly knew this was the sacred Bone Tree.
He saw dark red shades on one side, while on the other, he saw pure white shades.
The Sacred Bone Tree was half-corrupted!
But what shocked him the most were the things surrounding the Bone Tree.
Countless monsters walked out of the Giant Tree's trunk and moved in his direction.
'Shit, did I teleport near to the tree?'
As he was about to step back, he noticed another difference.
'No, they seemed to be unaware of my presence!' He quietly glanced around and soon saw a few figures battling the monsters on his right.
'Future vision?' As he looked closer at the half-elf figure, he confirmed his suspicions.
'More than 1000 Magical Beasts are surrounding us.'
All of those undead beings were corrupted and looked pure evil!
While looking, Abium noticed that the surroundings shattered into millions of pieces like glasses again and replaced with another scene.
In this vision, he saw multiple royal guards and soldiers surrounding Helena and Baron Auginare at a three-storied building's entrance and forced them to drop their weapons.
He also saw many nobles and knights standing over here and there and watching their misery in amusement.
'Auction house?'
He soon spotted a white-haired man with many wrinkles standing a few meters away from Helena and Baron and showed a greedy look.
'Count Tibal.' Abium raised his eyebrows as he realized what was happening.
'It means I died in this Undead Plane or didn't make it in time!' As he muttered, the surroundings started to break again and were replaced with a familiar scene.
Abium quickly found himself back in the frozen time and saw everything around him gradually returning to normal.
'What happened, Kid? Why is your heart pounding all of a sudden?' Azolla sensed the restlessness in his heart and asked.
'Visions.'
After taking a deep breath, he calmed his mind down and explained what he saw in those two visions.
'What are you planning to do?' Azolla asked.
"I need to figure out why I died in the vision. Otherwise, I might die again.' Abium spoke in a solemn tone.
