If Abium were to go all out against these few undead skeletons, he could easily eradicate them.
But that was not an option when he was up against 200 undead.
Although they weren't roaming nearby, he decided to hide his strength and only use sword skills now.
With that thought in his mind, Abium quietly moved towards the group of skeletons but soon frowned as he sensed someone's gaze.
At that moment, he glimpsed that one of the Elite Skeleton turned around, took out a wooden arrow, and placed it on the longbow.
Simultaneously, the skeleton aimed at longbow Abium while pulling the bowstring and released it with full force.
"Sh*t!" Abium cursed inwardly and ducked his head in a hurry.
Swoosh!
An arrow darted past his head and stuck on the nearby tree trunk a moment later.
Cold sweat dripped down from his forehead.
'No good.' He rolled on the ground, leaped towards the left side tree, and hid behind the tree trunk.
At that moment, another arrow flew from the skeleton and penetrated right next to his left leg!
A cerulean liquid came out of the arrow's apex the next second and released strange gas.
'Poison?' He showed a grim look and covered his nose not to inhale any air.
'Their cooperation is amazing!' He hurriedly touched his space ring, took out a mirror, and monitored their movements using it.
He saw two Elite Skeletons holding longbows in their skeletal hands, aimed the arrow tip, and walked towards him.
'They are quite skilled indeed. I will deal with the two archers first.' His eyes flickered in cold glint.
He leaped down from his hiding spot the next instant, sprinted towards the two archers in a zig-zag movement, and at the same time, used his sword to block the upcoming arrows.
Clang sounds reverberated in the woods as his sword collided with those arrow tips and deflected in different directions.
Abium soon arrived near the skeleton archers, made a whirling stance, and slashed his sword at their necks.
Two skulls flew up in the sky the next second and rolled on the ground.
Abium then calmly imbued mana into his Sword of the Wrath, enveloped the edges in the intermediate sunshine aura, and greeted the other skeletons.
At that moment, other Elite Skeletons also unsheathed their weapons and tried to encircle him.
But Abium didn't give them any chance and acted faster.
He sprinted towards the nearby Elite Skeleton, slashed at its head, and killed it swiftly.
Although sword and spear attacks came from other Elite Skeletons, he calmly parred against them, evaded all spear attacks, and stood against them equally.
'Still, these guys are quite strong. I feel like I'm fighting against well-trained soldiers!'
He didn't wait further and unleashed an intermediate-level sword skill.
Three lightning bolts came from his sword tip, quickly moved towards the nearby three Undead Elite Skeletons, and paralyzed their movements.
In truth, the mysterious power contained in the lightning bolts wasn't some electricity or lightning power but a unique type of sword aura.
The damage those three lightning bolts inflicted on those skeletons was pretty destructive.
Even some bones cracked up and caused the skeletons' movements to halt.
Utilizing that opening, Abium moved closer to one of the Elite Skeletons and thrust his sword at its head. His sword tore through the air while leaving a rippling noise and penetrated deep into its skull in a blink.
He instantly withdrew his sword, slashed it at the other two skeletons, and swiftly decapitated them.
At that moment, another three Elite Skeletons with spears in their hands leaped toward him, thrust their weapons in his direction, and forced him to back away.
But they too stood no match against Abium as he used [Blink] spell, disappeared from there, reappeared behind one of the Spear-holding Elite Skeleton, and calmly decapitated its head.
Following that, he moved his sword at an incredible speed and decapitated the other two Elite Skeletons.
Then, he turned towards the front and saw the remaining two Elite Skeletons.
At that moment, both held their long swords and trembled as they took two steps backward.
After all, he killed eight Elite Skeletons in less than 5 seconds, which startled them greatly.
They got frightened of his strength!
As he was about to move forward and eliminate the last two skeleton soldiers, a feeling of impending danger appeared in his mind.
Abium knew that his life would be in peril if he had stepped forward to kill the Elite Skeletons.
'That Skeleton Assassin?' His amber eyes squinted sharper.
He glanced around and noticed that the Skeleton Assassin seemed to have disappeared from there.
'He is lurking somewhere in the woods. I should finish these two first..' He muttered inwardly.
But the same dangerous feeling arose again as he thought of moving forward and killing the other two skeletons.
Without any delay, Abium cast the [Blink] spell, disappeared from there, and reappeared behind a tree trunk.
At that moment, the dangerous sensation disappeared, making him relax a bit.
'Was it my imagination? No. I felt an imminent danger a while ago. Hmm, I need to use the scan function now. But if I do that, I will also lose my concentration.' He didn't activate the scan function during the earlier battle because he knew that a bit of diversion could cost his life.
'Okay. I'll focus full attention on the surrounding when using the scan function and prepare for any unexpected sneak attack.'
He muttered as he released his spirit power and activated the 'Spiritual Scan' function.
A virtual map appeared in his mind the next instant and soon showed his enemy's location.
'Wait... The enemy is in the same place as I'm currently standing!' His face stiffened up.
'That assassin is lurking above me!'
He realized that the Skeleton Assassin was waiting for him to drop his guard down and turned grim.
'It seems I can't kill this one that easily.'
After some thoughts, Abium made up his mind and decided to do some tricks.
He first slackened his guard and concentrated his full attention on the lurking opponent.
Meanwhile, the Skeleton Assassin suddenly leaped from the tree, aimed its dagger at Abium's head, and descended to the ground at an unimaginable speed.
On the other hand, Abium calmly predicted its movement, suddenly raised his aura-coated sword and blocked the dagger.
To his surprise, he noticed that the bone dagger managed to remain intact and even released some strange greyish smoke around the bone!
'An artifact?'
The skeleton's strength wasn't much higher, and its weight was low.
So, Abium released more mana into his sword and covered it with an advanced sword aura.
The next instant, his sword directly shattered the bone dagger into multiple pieces and even split the Skeleton Assassin's head into two.
The Skeleton Assassin fell with a loud thud a moment later and went motionless.
'Tsk, the chaos stone is broken.' He heaved a heavy sigh, turned his gaze towards the remaining two trembling Elite Skeletons, and chuckled.
Although they panicked and desperately tried to escape, he chased after him and killed them quickly.
After that, he collected all the chaos stones from the defeated skeletons and stored them in his space ring.
Following that, he turned around and moved towards the oak tree.
A few minutes later, he reached the open grassland area and saw Nicolaus was cutting down many tree branches and gathering long vines from the nearby trees.
"Are you planning on making a fence around this tree?" Abium asked in a surprised tone.
"Yes. If multiple skeletons attack us, we will get some time to escape." Nicolaus paused for a moment as he recalled something and asked.
"What happened? Why did you come back so soon? I thought you went outside to explore this place."
"I also thought like that at first. But these skeletons' strength is different." A frown appeared on his forehead.
Meanwhile, Nicolaus went silent for a moment and asked.
"What are we going to do next?"
"I have a plan. But before that, I want to check something." Abium moved near the tree trunk, sat under the tree's shadow, and closed his eyes.
After that, he recited the usual incantation and entered the spiritual world.
Abium found himself in the empty void a second later and soon saw multiple white clouds hovering everywhere.
"As I thought, this place indeed has a treasure for mages." He muttered in a shocked tone.
It was the first time Abium had seen many clouds in the Spirit Realm, and he was dumbstruck inside!
He soon chose a nearby white cloud, took a small step, and hurriedly moved his foggy form towards it.
A few minutes later, Abium arrived next to a large cloud, touched it with his hands, and absorbed it.
A second later, he felt a slight increase in his soul form's quality and was pleased.
After that, he once again moved towards the nearby cloud and started his cloud hunting.
Two hours later, Abium reopened his eyes and showed a smile on his face.
It was the first time he managed to improve his Spirit rapidly, which made him pleased inside.
'It's time for me to construct my third spell model.' He muttered to himself, touched his space ring, and took out the spellbook.
