With the healing of the Endless Sword and Klein's growing magical powers, the intermediate Whirlwind has grown tremendously again.

At this point, the intermediate Whirlwind was activated, the power instantly reached 100 meters per second of speed.

As soon as it appeared, countless clouds of mist were swept away in an instant.

But there was too much poisonous fog in the entire world!

It was almost a vast expanse.

In the depths, even the color had turned black.

From afar, it made one's scalp tingle.

Klein had his own plans for using the intermediate Whirlwind.

That was because the growth rate of the intermediate Whirlwind was no weaker than the half-step natural disaster that Klein had just begun developing.

And most importantly, other spells couldn't stir up the fog in such a large world.

Of course, a half-step natural disaster could do it.

But the problem was that a half-step natural disaster required too many spells.

If he consumed too many spells before meeting the enemy, it might affect the upcoming battle.

Klein didn't want to suffer the pain of having his mana depleted again.

Of course, the most important thing was that there was no land in this world.

Klein didn't want to come into contact with the poisonous lake below!

At that moment, the intermediate Whirlwind was growing at a rapid rate.

It immediately stirred up countless amounts of fog.

The fog in front of Klein's eyes disappeared at a speed visible to the naked eye.

But at that moment...

A magical fluctuation came from the depths of the fog.

A beam of light whizzed out and shattered Klein's intermediate Whirlwind.

"Don't you want to dispel it?"

"But that's not up to you."

With this in mind, Klein cast the intermediate Whirlwind once again.

This time, he cast four at once.

Then, under Klein's control, it quickly flew in all directions.

The intermediate Whirlwinds that flew out stirred even faster.

And this time, the Poison Dragon didn't make a move.

An hour later, the fog in front of Klein's eyes became less and less.

He could already see the outline of the entire mountain peak from within.

He could also see two eyes that were like giant lanterns.

The speed of the intermediate Whirlwinds was even faster.

The wind speed inside reached 150 meters per second.

From afar, it looked like a pitch-black dragon was about to be born.

Soon...

The fog had completely disappeared.

At that moment, everything on the mountain appeared in front of Klein.

Looking at everything in front of him, Klein widened his eyes.

"This is?"

It was indeed a gigantic dragon in front of him.

But what was unbelievable was that the gigantic dragon wasn't coiled up on the mountain. Instead, it was locked up on the mountain.

Countless pitch-black chains bound the gigantic dragon from head to toe.

And the distance was also very large.

Just the dragon head that was revealed was as tall as a dozen stories.

Klein stood in front of him as tiny as a speck of dust.

It looked coldly at Klein.

It felt the annoying bugs around it tearing apart.

It roared impatiently, and a sound wave that seemed to have substance instantly radiated out from its body.

And any intermediate Whirlwind that came into contact with the sound wave was instantly sent flying hundreds of feet away as though it had suffered a huge blow.

But it wasn't over yet.

The Poison Dragon made its move.

It opened its bloody mouth and let out an earth-shattering roar at the four Whirlwinds.

Instantly, a beam of green energy was released.

Wherever it passed, none of the intermediate Whirlwinds could withstand it and were instantly annihilated.

And at that moment, Klein didn't stop. Instead, he used the Poison Dragon to destroy the intermediate Whirlwinds.

After casting the power of wind, he raised a huge knife and charged at the Poison Dragon.

One had to know that Klein's strongest attack wasn't magic, but physical attacks.

This was augmented by the Power of the Wind and the Endless Sword. Its augmentation was 90% higher.

What kind of concept was this?

Klein's attack was originally 1,000, but after the double augmentation, it reached around 2,000.

Of course, Klein's attack power was far more than that.

Therefore, with this huge boost, Klein raised the Endless Sword and charged at the Poison Dragon.

At that moment, the Poison Dragon also sensed Klein's weapon.

In its haste, it could only let out a terrifying roar at Klein.

The Poison Dragon's roar contained a terrifying sound wave that instantly swept towards Klein.

As there was only one target, the terrifying sound wave was even more powerful this time. Wherever it passed, the space would produce cracking sounds. Clearly, it couldn't withstand the power of the sound wave.

Looking at the incoming sound wave, Klein narrowed his eyes. He could sense the terror of the sound wave. If it was before, he would have used earth magic to block it.

But now, there was no earth magic.

However, looking at the sound wave in front of him, he had a feeling that he could withstand it head-on!

With this thought in mind, Klein stopped dodging.

He grabbed the Endless Sword with both hands and held it above his head as he slashed at the sound wave.

He shouted, "Die!"

Then, the beam saber that was a few meters long smashed into the sound wave.

Instantly, the sound wave shook.

There were rumbling sounds coming from both sides. It looked like they were neutralizing Klein's attack.

But how could Klein's attack be so easily resisted?

However, Klein didn't let go. Instead, he launched another Vacuum Strike.

Klein gritted his teeth and resisted the sound wave.

The power of the sound wave couldn't be underestimated.

Waves of power constantly pushed Klein back.

But Klein held on and didn't retreat at all.

This was because he knew that the Poison Dragon was currently in the process of casting a spell. Once he retreated, although it would be difficult to hurt him, the sound waves would still be able to push him a hundred meters away.

By then, the Poison Dragon would definitely recover, and it would be difficult for him to get any closer!

Therefore, Klein gritted his teeth and roared, "Vacuum Strike!"

Instantly, countless Vacuum Strikes made use of Klein's strength to slash at the sound waves inch by inch.

One slash!

The sound waves didn't move, and the Vacuum Strikes dissipated.

Two slashes.

The sound waves still didn't move, and the Vacuum Strikes still dissipated.

Three slashes.

This time, the Vacuum Strikes made a meritorious contribution.

Cracks appeared on the sound waves, producing a cracking sound.

But it was still able to hold on.

As Klein's attacks became more concentrated, the sound waves, which were like rootless duckweed, finally couldn't hold on any longer.

As the cracking sounds grew louder, countless cracks spread out along the edges of the Vacuum Strike.

As the final Vacuum Strike slashed out.

There was a boom.

The sound waves could no longer withstand it.

Under Klein's Vacuum Strike, it was like glass shattering. It instantly shattered inch by inch and fell into the poisonous lake.

Klein also used the power of the Vacuum Strike to continuously advance.

In the end, he successfully made it to the front of the Poison Dragon.

He looked down at the Poison Dragon!
