But before Klein could recover, the red lightning in the sky changed again.

Thump!

Instantly, red lightning exploded in the sky.

The entire sky was dyed red by the red lightning.

From afar, it looked as though the place had experienced a cataclysm.

Klein felt a massive fluctuation in the sky.

He couldn't help but feel his heart stagnate.

He thought to himself, 'I didn't expect the lightning to be so powerful. It looks like it's also a powerful killing move.'

With this in mind, Klein didn't dare to be careless.

After all, just a single red lightning bolt had caused his right hand to lose power.

If so many lightning bolts were to descend on him, would he still have a chance of survival?

However, it wouldn't be so easy to resist the lightning.

Sensing the lightning that was accumulating in the sky, Klein knew that the longer it accumulated, the more difficult it would be for him to resist. Therefore, he had to take action before it finished accumulating.

Then, Klein looked at the Poison Dragon.

He had wanted to ask something.

But from the looks of it, the Poison Dragon had treated him as its mortal enemy.

Since that was the case, he would take it down first.

Following that, Klein picked up his sword and charged at the Poison Dragon with the tip of his toes.

At that moment, the Poison Dragon looked at Klein, then at the sword in his hand.

It wasn't stupid. It naturally knew that the sword in Klein's hand was definitely not an ordinary item.

That was because the legendary weapon could indeed pierce through its teeth, but it was absolutely impossible for it to cut off all of its teeth.

One had to know that many of its teeth were densely packed together.

With the superposition, its defensive power had already reached the level of a legend.

Therefore, what was the only weapon that could pierce through a legend?

A divine weapon!

With this in mind, the Poison Dragon's expression turned solemn.

As a powerhouse in the catacombs world, it naturally knew how powerful a divine weapon was.

It was precisely because it knew that it didn't dare to let Klein get close.

With this thought in mind, the Poison Dragon couldn't be bothered to heal its injuries.

Instead, it directly controlled the magic in the sky and released it. Even if it wasn't in its strongest state, it couldn't let Klein get close to it.

Whoosh--

The heavenly lightning exploded once again.

This time, the sound was even more terrifying.

It was as if the entire space couldn't withstand the power of the lightning, producing cracking sounds.

As for the monsters that flew up from below, they couldn't withstand it either. Many of the monsters were too close to Klein, and their heads were blasted apart by the sound waves.

Klein sensed the situation in the sky.

He hurriedly stopped and looked up.

He saw countless bolts of lightning raining down on Klein.

However, Klein didn't panic.

He calmly responded.

Suddenly, he saw that something was wrong with the lightning in the sky.

As the red lightning descended faster and faster, the red lightning became denser in Klein's eyes.

It was like raindrops, densely packed, with no gap for the wind to pass through.

But at that moment, Klein noticed a problem from his keen observation.

"That's not right! The lightning isn't completely impenetrable."

Amidst the dense lightning, there was a very narrow area that wasn't covered by the lightning.

The lightning was too dense.

Even Klein had to wait a long time before he noticed it.

If it were anyone else, they would have panicked long ago and wouldn't have noticed this detail.

Seeing that the lightning didn't cover the area, Klein didn't plan on making a move.

That was because there were still countless monsters under him.

Although it wasn't difficult to kill them, it still required magic. It was better to let them fight each other.

With this in mind, Klein flew over and stood under the lightning.

When the Poison Dragon saw this scene, it couldn't help but sneer.

"You're really courting death! Why aren't you making a move despite your arrogance? Do you really think that the magic of a peak tier 8 Poison Dragon is made of paper?"

"But that's good as well. Don't think that you can withstand such a dense attack with just your divine artifact. Even a tier 9 powerhouse wouldn't be able to survive, much less if you have a divine artifact."

Then, the Poison Dragon glanced at the monsters below.

It didn't care.

To it, these monsters were just little things that relied on it to survive.

As long as they could kill Klein, it didn't matter if they died.

The monsters underground also felt the lightning in the sky.

However, many of the monsters were stained with blood and their faces were flushed red. They didn't dodge at all.

However, there were even more intact monsters that were acting strangely.

And at that moment, a beast roar sounded from below, urging everyone to quickly enter the poison lake to hide.

The monsters didn't dare to be careless.

They turned their heads and plunged straight into the poison lake.

But it was clearly too late.

Furthermore, there were too many monsters.

In an instant, the heavenly lightning struck, and the area within a few hundred meters instantly entered the sea of lightning.

Countless monsters that didn't have time to escape were instantly struck by the heavenly lightning. They didn't even have the chance to scream before they were blasted into pieces and died a tragic death.

And at that moment, the Poison Dragon was staring intently Klein. It could clearly see that Klein didn't even make a move to resist the second the heavenly lightning struck.

It knew that Klein was bound to die.

Therefore, it couldn't help but reveal a cruel smile.

"Hmph, how could you be so careless! I'll take your head, and of course, your Endless Sword."

"A divine artifact should be able to remove the damnable chains on my body, right?"

At the same time.

Deep in the lightning, Klein knew that he had made the right choice.

The lightning was indeed very dense.

It was so dense that it looked like raindrops falling from the sky.

However, the spot where Klein was standing was completely unaffected.

Not only that, Klein also looked at the lightning that streaked past his eyes with interest.

He couldn't help but wish that he had a cup of tea at that moment.

Soon, the first wave of lightning passed.

At that moment, countless monsters within a hundred-meter radius were blasted into dregs.

The poisonous lake that was as black as ink was now filled with blood, wreckage, and short limbs.

Many of those who had survived by chance were now completely charred. Although they were still alive, it was only a matter of time before they died.

As for the originally flat poisonous lake, it had been blasted into a huge crater by the dense lightning.

There were even quite a number of corpses that were burning in it.

As for the Poison Dragon, which was staring intently at Klein's figure, it didn't care about any of this.

After the lightning dissipated, the first thing it saw was Klein.

But in an instant!

The Poison Dragon was stunned.

After the lightning dissipated, not only did Klein not die, he looked as calm as the wind and clouds.

Even his clothes were intact.

"What's going on?"

"That's impossible. With such a dense lightning bolt, even a tier 9 wouldn't be able to withstand it perfectly, let alone a tier 8!"

"Furthermore, this human didn't cast any defensive spells, and it's even more impossible for him to withstand the dense lightning bolt!"

The Poison Dragon widened its eyes as it stared fixedly at Klein. It kept scanning up and down, trying to find the reason why Klein wasn't injured at all!

But it was disappointed.
