The seventieth catacomb!

Eight meters in the air.

Klein's eyes were fixed on the ground.

It was a black hole.

"I came to deliver something to you."

Boom! Boom! Boom!

Klein released three fire elemental missiles in a row.

The three elemental missiles accurately smashed into the black hole.

A few seconds later, an angry roar came from the black hole.

"How is it? It doesn't feel good, does it? If that's the case, how long do you plan on staying in there?" Klein shouted loudly in the underground common language.

The Golden Sand Dragon let out another angry roar.

He understood it.

But it seemed to be limited to understanding, and it couldn't communicate in the underground common language.

'What? Are you planning to cower like a turtle? Then, I'll continue to let you taste it.'

Klein's gaze focused as he sent another three fire elemental missiles into the black hole.

Boom! Boom! Boom!

The flames released by Klein from the three fire elemental missiles were even hotter.

Their power was much greater than the previous three.

This could be seen from the Golden Sand Dragon's even angrier roar.

It couldn't bear the two attacks from Klein.

A huge tail quickly stabbed out from less than five meters below Klein.

It was extremely fast!

It could be said that it was even faster than the first time.

However, Klein was already prepared.

He turned sideways and easily dodged the attack.

When it saw that its second attack had missed, the Golden Sand Dragon was furious.

It launched a series of tail attacks at Klein.

However, after a series of attacks...

Klein easily dodged them all.

"An attack of this level is completely unable to hit me, you bug!" Klein shouted disdainfully to the ground.

These words seemed to have completely stimulated the Golden Sand Dragon's self-esteem.

It completely infuriated it.

Soon, the sand on the ground began to shake violently.

It produced regular undulations.

Upon seeing this, Klein immediately raised flying height.

He returned to a height of 12 meters.

His eyes were fixed on the undulating ground, ready to counterattack at any moment.

Suddenly, a gigantic figure appeared on the ground.

It was the Golden Sand Dragon!

It charged at Klein.

It opened its bloody mouth!

It wanted to swallow Klein alive.

Although it was only for a few seconds, Klein could clearly see the true face of the Golden Sand Dragon.

Compared to the ordinary Sand Dragon he had encountered before, this one was about five times larger.

Furthermore, its entire body was covered in golden leather armor.

There were no signs of injuries on its body.

'Could it be that my flames didn't cause any damage to this fellow?'

'Or could it be that this fellow has extremely powerful self-healing abilities?'

Klein quickly dodged the Golden Sand Dragon's pounce.

At the same time, he automatically gave up on the second thought.

This fellow's golden armor was able to completely resist the flames!

And the reason why it roared wasn't because of the pain, but because it felt humiliated!

However, just as Klein was thinking...

In the next second...

The Golden Sand Dragon swung its tail at Klein the instant it landed!

This time, Klein was nearly hit.

If not for Little Fox and Little Wind's reminder, Klein wouldn't have reacted at all.

His attention was completely drawn to the Golden Sand Dragon.

Klein gritted his teeth and said to himself, "That was close. I can't do it again."

This time, Klein focused all his attention on dealing with the Golden Sand Dragon.

His brain couldn't allow himself to think at all.

Even if he was thinking, he had to ensure that he was thinking while paying attention to the other party's movements.

After the Golden Sand Dragon fell into the sand, it dived underground again.

When will the next attack be? Which direction will it come from? What attack method will it choose?

Klein's mind spun rapidly.

At the same time, his eyes were staring intently at the sand.

At the same time, he constantly released fire elemental missiles at the ground.

These fire elemental missiles constantly smashed into the black hole.

Klein knew that doing so wouldn't cause any harm to the fellow.

He was only doing this to disrupt the other party's emotions!

At the same time, Klein consumed the Seed Explosion Blood Pill.

It was the item he had just exchanged from Roger.

Originally, Klein had planned on using the Seed Explosion Blood Pill under extremely dangerous circumstances.

But now, Klein felt that he had to do it.

Not long after consuming the Seed Explosion Blood Pill, the second attack came!

This time, the Golden Sand Dragon pretended to attack.

First, it let its tail strike.

When Klein reacted and dodged, its entire body jumped out to attack Klein.

This greatly reduced the time that Klein could react.

If the previous Klein had 0.5 seconds to react, the current Klein didn't even have 0.1 seconds.

If this were in the past... Klein would definitely be gone.

But it was different now.

After consuming the Seed Explosion Blood Pill, Klein's strength and speed were ten times faster than before!

In just 0.1 seconds, Klein completely dodged it.

At the same time, Klein also used a few fire elemental missiles on the Golden Sand Dragon.

The missiles landed on the surface of the Golden Sand Dragon.

It only produced a spark.

Then, it disappeared.

It didn't do any damage to the Golden Sand Dragon!

This confirmed Klein's guess.

"Doesn't this fellow have any weaknesses?"

From the looks of it, Klein's main attack didn't do any damage to the Golden Sand Dragon.

As for Little Fox, her advantage lay in her speed. However, no matter how fast she was, it was useless if she couldn't harm the Golden Sand Dragon.

Not to mention Little Wind, the hardness of the golden armor was probably higher than Little Wind's hard armor.

'What should I do?'

Klein frowned.

He watched as the Golden Sand Dragon returned to the ground.

Then, in less than ten seconds, the Golden Sand Dragon attacked Klein again.

The method was different from before.

Klein could only dodge as he tested the Golden Sand Dragon's weakness.

He had to finish it off before the effects of the Seed Explosion Blood Pill disappeared.

Although the current situation had caused Klein to engage in a bitter battle, he still maintained his calm mind.

After probing again and again, after the Golden Sand Dragon failed in one attack, it chose to dive to the ground again.

At that moment.

Klein suddenly noticed that a small part of its abdomen wasn't covered by the golden armor!

Although it wasn't large, it was enough for Klein!

As long as he attacked this area, he would have a chance of defeating it!

With this in mind, Klein took a deep breath.

The next time the Golden Sand Dragon attacked, Klein only needed to aim at the empty space in its abdomen and fire elemental missiles!

Furthermore, after dozens of exchanges...

Klein had already completely figured out how the Golden Sand Dragon attacked.

However, for some reason.

Ten minutes passed, but the Golden Sand Dragon didn't jump out of the ground to attack Klein.

"Since you're not coming out, I'll look for you," Klein said as he looked at the surface.

Then, he let Little Fox and Little Wind put on their fish clothes and told them how to fight.

When everything was ready, Klein released a few fire elemental missiles at the black hole again.

Then, he led Little Wind and Little Fox straight underground!

This time, Klein wanted to completely end this Golden Sand Dragon!
