At this moment, Little Wind had also walked out from the illusion.

He quickly ran to Klein's side and kept rubbing against Klein's thigh.

Just now, he had experienced a very terrifying illusion.

At first, everything was normal.

But later, Little Wind found out that he had gone everywhere.

This made him especially uncomfortable.

Therefore, the situation was similar to that of Little Fox.

In short, it was very dangerous.

However, this uncomfortable situation didn't last for more than a few seconds.

Little Wind returned.

"From the looks of it, this Illusion Ring is indeed powerful," Klein muttered to himself.

Now, he needed to go to the catacombs to test it out.

Klein left the runic base immediately.

"Little Fox, Little Wind, go."

[In the catacomb ahead, there's a little squirrel. This little squirrel is very cute, but please don't be fooled by its cute appearance. You have to know that this squirrel is actually a hungry wolf. Its real warning is about two meters away. It has a very powerful bite force.]

[In the catacomb behind, there's a Potato Monster. This Potato Monster is covered in potatoes, and it's the kind that can be eaten. However, if you eat it, you will be poisoned.]

[In the catacomb to the left, there's a group of zombies! The brains of these zombies are filled with green brain matter, and the blood all over their bodies is green. If you are bitten by this zombie or disturbed its droplet, you will be infected into a zombie.]

[In the catacomb to the right, there's a Mask Monster. It has many masks. This creature from the catacombs also appeared in the last notification. Its mask represents different emotions, and each emotion has different effects.]

After thinking about it, Klein felt that the Mask Monster was more in line with its thoughts.

'Then, let's give this Mask Monster a try.'

Without much thought, Klein directly chose to enter the catacomb on the right.

"The two of you can try elemental transformation," Klein said to Little Fox and Little Wind.

'Things like elemental transformation, once used properly, will be very powerful,' Klein thought to himself.

After all, they could ignore all physical attacks for a short period of time. This attribute was already enough to crush many crypt creatures.

Little Fox and Little Wind nodded at the same time.

The 110th catacomb!

After Klein entered the catacomb, he immediately felt a sinister atmosphere.

This feeling was extremely uncomfortable.

It was like an indescribable feeling.

It was inexplicably disturbing.

It was as if someone was secretly watching him.

"Who is it?"

Klein shouted.

His voice echoed throughout the entire catacomb.

'It must be that Mask Monster,' Klein analyzed.

However, there was no movement in the entire catacomb.

The monster didn't come out!

"Are you playing hide-and-seek with me?"

Klein looked around the catacomb.

The entire catacomb was smaller than most catacombs.

However, there were many types of shelters.

There were also many potholes in the ground.

"Wuwuwu. Who's going to save me?"

Suddenly, the cry of a young man came from Klein's left.

"Someone's here?"

Klein immediately turned his head and saw a very thin, long-haired man squatting on the ground. He was hugging his knees and leaning his head against his painted joints.

The man was trembling all over.

He kept saying these words.

"There's actually someone here? Could it be that someone entered this catacomb before me?"

'Impossible!'

'I'm definitely the first person to enter this catacomb'.'

'It's impossible for someone to be here before me.'

Klein immediately rejected this idea.

Therefore, this person was fake.

Klein immediately came to a conclusion.

How could he be wrong? This person must be fake.

Klein immediately used the fire elemental missile to smash at the man.

The man quickly revealed his true appearance. He saw that the elemental missile and knew he couldn't dodge it.

'I'll stop pretending.'

'I'll show my fangs.'

'I'll crush the fire elemental missile with one bite!'

The teeth were completely fine.

This tooth and mouth were too strange.

'They can actually swallow my fire elemental missile?'

Ten thousand question marks instantly rose in Klein's heart.

'This crypt creature is a Mask Monster. What powers does it have?'

The hint just said that this fellow's powers are related to the mask's emotions.

The mask's ability can actually bite through flames?

Anger?

However, this fellow was clearly crying just now.

It didn't seem like anger.

Klein kept guessing in his heart.

This feeling was very strange.

Klein felt that this crypt creature was somewhat powerful.

Another few fire elemental missiles were all bitten to pieces by this man and swallowed.

'As expected, this guy ignored my physical attacks?'

'What if the flames are a little bigger?'

Klein was somewhat unwilling.

Fireball!

Klein released the biggest flame he could release at the moment.

The powerful power of the flames directly devoured the man.

However, the flames dissipated, and the man was safe and sound.

"Heh heh, interesting. I didn't expect you to be a charm warlock."

The man slowly spoke.

"Are you a human? Or a Mask Monster?" Klein asked.

"Oh? You actually know my name?"

A hint of shock flashed in the man's eyes.

"Heh heh, my identity is very special. I can change into whatever identity I want."

"For example, this."

Soon, the man changed his face.

He turned into a young woman.

This woman was very charming.

But Klein had seen too many beautiful women.

This was really nothing.

Klein chuckled.

He continued using the water element.

Missiles!

These water element missiles were completely ineffective against this woman.

'As expected, my current physical attacks can't hurt her at all.'

Klein analyzed in his heart.

This person's mask could be changed into different forms, and each form should have a unique ability.

How could he solve it?

Klein's brain began to spin rapidly.

He really didn't know how to solve it.

Death Ray!

Klein immediately fired the Death Ray.

After the ray hit the woman, the woman's expression instantly changed.

It worked!

Klein's eyes flickered.

If it worked, there was a chance of victory.

After the woman was hit by the Death Ray, her entire person was completely deformed.

It distorted!

Following a tragic scream.

The woman instantly revealed her true colors!

It was a gray, extremely ugly mask!

[Mask of Depression: It can transmit negative emotions to people. It can release many negative emotions. Through vision, it can infect people with negative emotions, resulting in them entering a very negative mode.]

'So, as long as I don't look, it's fine?'

Klein instantly closed his eyes.

Then, he used his hearing to determine the direction of the mask.

"Heh heh, do you think that I can't do anything to you just because you're like this? Naïve!"

The mask let out a strange laugh as it released a lot of sound waves.

These sound waves were very ear-piercing. Although they didn't bring any other fear to people, they made people's ears feel uncomfortable.

Even if they covered their ears, they could still hear very clearly.

'This guy seems to be a bit of a handful!'
