What exactly was it?

The questions in Klein's heart grew bigger and bigger.

From the very beginning when he was fighting the Mirror Monster, this fellow actually didn't show up at all.

It just patiently watched the two of them kill each other.

Then, the crux of the matter was that when Klein killed the Mirror Monster, this fellow actually didn't react at all.

This was the strangest thing. Logically speaking, after the fellow saw Klein kill the Mirror Monster, shouldn't it have immediately dealt with Klein when he let down his guard?

'Why didn't the fellow make a move at that time?'

Klein still couldn't figure it out.

And from the battle between Klein and the fellow, the fellow was really very cautious.

Very cautious.

It was more cautious than Klein knew. This was really something that Klein couldn't understand.

However, this caution gave Klein a very powerful feeling.

That's right, it was a very powerful feeling.

Klein felt that this fellow was definitely not an ordinary crypt creature.

This fellow's strength was definitely far above the monster in the mirror.

That's right, there was an unknown crypt creature in this mirror.

There were two of them!

There might even be more!

After all, Klein didn't know if there would be any new crypt creatures appearing from the howls of this crypt creature.

This was another thing that he was worried about.

What if another crypt creature appeared after killing this crypt creature? What should he do?

When Klein thought of this, he couldn't help but feel a little vexed.

However, Klein couldn't care less about the hunch.

After all, if he didn't kill the Mirror Monster, Klein wouldn't be able to leave this world.

Therefore, no matter what, Klein had to kill the creature.

Klein didn't know that at a time like this, he could organize himself to kill this crypt creature at a time like this.

But now, he had to do it.

At this moment, the footsteps of the crypt creature were getting closer and closer.

Klein could clearly hear the footsteps.

There were about eight feet!

'What kind of crypt creature is this!'

'Could it be a sewn-up monster?'

However, Klein wasn't sure.

After all, the catacombs world was so large, and there would be many types of crypt creatures in it.

This was very normal.

However, no matter what kind of crypt creature it was, Klein felt extremely pressured.

That's right, it was a lot of pressure.

But that wasn't important.

What was important was that Klein had to kill this crypt creature now.

Klein knew that it was less than fifty meters away from him.

In his hand, he held the Golden Firestorm Saber tightly.

'Soon. With a few more steps, this fellow will appear in front of me.'

At that time, Klein would jump out of the ground and directly stab the crypt creature.

However, this fellow was clearly not afraid of flames, so there was no point in having flames attached to the Firestorm Saber.

And this Golden Firestorm Saber was capable of cleaving apart the existence of a Golden Sand Dragon. The hardness was definitely without a doubt extremely powerful.

Therefore, Klein believed that he would definitely be able to cleave the other party to death.

With such determination, Klein quietly waited for the arrival of this crypt creature.

The fellow's footsteps were getting closer and closer.

Klein could clearly hear the fellow's swing.

It was mixed in with the footsteps.

However, Klein felt that the crypt creature's breathing was very light.

No wonder Klein didn't discover the fellow's location.

It turned out that it had a lot to do with the fellow's breathing.

Klein waited, but he could continue waiting.

He knew that he couldn't be anxious at this moment.

Klein had already endured the long wait just now. How could he not endure it now?

Klein held the Firestorm Saber. There were still thirty meters left!

Twenty meters!

The distance was getting closer,

Klein's heart began to beat a little faster than normal.

It couldn't be fake.

However, he wasn't that nervous.

But more or less, there was still a little.

Ten meters!

Only ten meters!

Klein took a deep breath. He wanted to see how nervous he was during the segment.

Sweat was already dripping from Klein's palms.

Klein knew that this was a very important critical moment.

He definitely couldn't drop the ball so easily.

This fellow was getting closer every now and then.

It was getting closer.

Klein could feel it.

Five meters!

Three meters!

Klein's right hand was already prepared with the Death Ray.

If he didn't succeed in killing his opponent with the Golden Firestorm Saber, he would use the Death Ray to corrode his opponent.

The Death Ray had never failed before. This was Klein's confidence.

The Death Ray was Klein's strongest physical attack.

If that wasn't enough, he would use the Illusion Ring.

The strength of the Illusion Ring was enough to defeat the masked monster with a single sentence.

This also meant that Klein's current strength was very powerful.

It wasn't something an ordinary person could touch.

And now, Klein felt that it was very easy to deal with the Mask Monster with these skills.

That's right, Klein should constantly give himself confidence. How could he give up halfway?

At this moment, there was no need to be afraid.

He had to face it head-on!

The Golden Firestorm Saber in Klein's hand was completely prepared.

He had been waiting for this moment!

The next second.

He heard another set of footsteps.

Klein knew that there was still one meter left!

Zero meters!

'It's here!'

Just as Klein was about to walk out of the ground, and strike a fatal blow, it opened its mouth.

"Strange, where is that guy? It should be here by now. Why don't I see him at all?" said the crypt creature in front of him.

The voice is also hoarse.

But compared to the previous fellow, it was much better.

At least, the degree of hoarseness wasn't that exaggerated.

It was just that it made people feel uncomfortable.

But due to the fog, Klein couldn't see the fellow's face clearly.

That's right, this was the only bad part.

But in order to confuse the fellow's vision, Klein had no choice but to do so.

This was also Klein's goal.

Suddenly, a disdainful voice sounded from the fellow's voice.

"Could this fellow be hiding from me? Is he deliberately luring me out?"

"Heh heh. If that's what he thinks, then he'll be in trouble. After all, I'm different from that trash. I'm a hundred times stronger!"

The hoarse voice suddenly increased in volume.

It reverberated throughout the entire catacomb.

No, to be precise, it was the Mirror World.

Just like that, Klein waited as he listened to the fellow's voice.

"Wait? This fellow can't be underground, right?"

Suddenly, the hoarse voice sounded again.

Klein was instantly alarmed.

He... was discovered?
