Klein’s heart shrank when he heard the sound.
Then, he looked around.
Suddenly, the world changed color.
The entire world shook.
It was as though something had been alarmed.
Before long, the originally calm puddle began to ripple.
As for the clouds in the sky, they seemed to turn darker, as though something was coming.
As for the sun, it was even darker.
“Not good!”
Klein sensed something.
He immediately activated the Explosive Speed skill of Rogue Archer’s Half-High Boots.
In an instant, Klein flew into the air.
And when he looked down…
A pitch-black creature had appeared where he was standing previously.
Bone spikes that were three to four meters long rapidly grew out of the creature’s body.
The bone spikes were extremely sharp.
Under the dim green sun, they flashed with an indescribable light.
Soon, the creature roared.
With a leap, it flew up.
This roar was like a water stain that had been thrown into a pot of oil.
Instantly, the mountain range where it stood began to riot!
At this moment, Klein’s eyes were about to pop out of their sockets.
He couldn’t help but think to himself, ‘What world is this?’
In his eyes, the mountain range seemed to have come to life.
No!
It wasn’t coming to life, but moving.
It wasn’t the entire mountain, but a mountain of corpses.
The corpses seemed to have been alarmed by the roar.
They stretched their bodies and began to move.
First, it was their wings, then their legs, and finally, they came to life.
Then, they let out a roar as well, as if they were responding.
Soon, all the corpses on a mountain came to life.
They fought to be first.
One after another, they flew up and whistled towards Klein.
Looking at the corpses flying towards him, Klein frowned.
The hind legs were fast.
It wasn’t that he was afraid, but that this creature was very strange.
Without knowing its strength, he decided to be safe first.
This was only the vanguard.
Soon, more and more mountains were awakened.
If Klein could see them now, he would be extremely surprised.
This was because the mountains weren’t just made up of flying corpses. There were also countless corpses on the ground.
The resurrected corpses seemed to have been guided as they rushed towards Klein.
The corpses in the sky were very fast.
With the sunlight in the sky, Klein quickly saw their true colors.
They were dragons!
No, they seemed to be a hybrid species.
Not only did they have wings, they didn’t even look like their bodies.
They seemed to be some kind of flying creature.
The only difference was that these creatures seemed to be dead.
The thing that drove them was that pair of strange eyes.
That’s right.
Of all the flying creatures, only their eyes were red.
Therefore, Klein guessed that the red eyes should have given them the motivation.
The flying creatures were very fast.
Even if they were dead, their bodies didn’t stiffen in the slightest.
Klein’s speed wasn’t slow either.
But he wasn’t a flying unit after all.
Even if he flew first, they were rapidly closing in on each other.
“I can’t do this anymore!”
Klein looked back.
He hadn’t looked for a while.
There were even more creatures in the sky.
At that moment, the entire sky behind Klein was blocked.
Thankfully, Klein was flying very high.
Otherwise, the entire world would have turned into a battle between darkness and light.
Klein stopped.
He stood in midair.
The Explosive Speed was still not over.
Klein still took the initiative.
But he was very cautious.
Then, he took out the Endless Sword.
He chanted silently, and then the Endless Sword was displayed.
Seven or eight Whirlwind spells were born on the Endless Sword.
Then, Klein extended his wrist, and seven or eight Whirlwind spells charged at the densely packed creatures in the sky.
There was no terrifying brilliance when the two collided.
Instead, Klein’s Whirlwind was like a sharp knife.
It crashed straight into the flying creature.
Rip!
Instantly, the creature that came into contact with Klein’s Whirlwind was mercilessly annihilated.
At that moment, flesh and blood splattered in all directions as blood splattered everywhere.
If there was someone down there, it would definitely be extremely shocking.
At that moment, the countless blood droplets in the sky were like rain as they scrambled to fall.
Looking at the damage caused by his skill, Klein was stunned for a moment.
In fact, this was his first time using this skill.
Back when he was fighting the Rogue Archer, Klein had only just started researching it, so he wasn’t very familiar with it.
Later on, Klein was afraid of injuring the two beasts, so he didn’t dare to use Whirlwind to deal with them.
But now, it seemed like the might of Whirlwind had greatly exceeded Klein’s expectations.
The Whirlwind was like a meat grinder, crazily charging into the flying creatures and mercilessly slaughtering them.
Seeing how powerful his Whirlwind was, Klein wasn’t the least bit happy.
This was because these creatures weren’t moved at all. Instead, they continued charging at Klein fearlessly.
If it were any other situation, Klein wouldn’t have minded.
The level of these creatures wasn’t high.
This was because when he used the Whirlwind spell to deal with the Rogue Archer, although it was tragic, it was far from an instant kill.
However, the creatures in front of him couldn’t withstand the Whirlwind spell at all.
Once they came into contact with it, they would be ground to death.
Therefore, Klein guessed that these creatures weren’t high-level.
But even if they weren’t high-level, their numbers were still terrifying!
Even though Klein had killed many of them, there was still no sign of their numbers decreasing.
Not only that, the Whirlwind spell, which had killed a large number of flying creatures, was beginning to fail.
The spinning speed was slowing down. It was obvious that they had used up all their mana and were about to fall at any moment.
And once they fell, it would be the signal for the creatures to charge again.
Therefore, Klein couldn’t delay any longer.
He had to think of a way to kill all of them.
At that moment, a Whirlwind spell couldn’t be blocked.
It was instantly dispersed by the later creatures.
This creature was very fast.
It was even faster than the dragon-like speed from before.
It used its acceleration to instantly arrive in front of Klein.
Without saying anything, it raised its claws and clawed straight at Klein’s face.
Klein was startled.
But he didn’t panic.
He took a step forward and retreated rapidly.
Then, with a wave of his hand, he used a few more Whirlwind spells to charge forward.
At that moment, the system’s notification appeared.
[Poison Wind Fire Dragon Beast, Corpse, Tier 4]
[Advantage: Very fast, extremely lethal.]
[Disadvantage: Very low defense.]
Klein swept through the system’s notification.
And the Poison Wind Fire Dragon Beast was instantly killed by the Whirlwind spell.
But Klein made his move too late.
More and more Poison Wind Fire Dragon Beasts broke through their defense and charged at Klein.
Klein wasn’t in a hurry.
After reading the system’s notification, Klein had an idea.
But now wasn’t the best time to execute it.
Therefore, Klein chose to pull.
It was very fast, leaving an afterimage in the sky.
And the Poison Wind Fire Dragon Beasts took the lead and pounced at Klein!
