After returning to the catacombs, Klein had a lot on his mind.

The world just now was too surreal for him.

Was this really a real world and not a dream?

But when he saw the necklace in his trouser pocket, Klein knew that it was definitely not a dream.

From the looks of it, he had really entered a very wonderful world.

This experience really made him feel awesome.

He was the first person to have such an experience.

It was truly unbelievable.

Klein's thoughts kept flowing.

He had only gone to the Fantasy Forest for one night.

The world didn't change much either.

Opening the world channel, Klein took a look at what everyone was discussing.

It seemed to be the same as before. There was nothing special about it.

After understanding this point, Klein had no other thoughts.

He opened the runic base.

Klein came to the greenhouse.

The Silkworm Tree's seed had already sprouted.

This was good news.

When he saw this plant grow, Klein was very happy.

After returning to his place, Klein lay on the bed and closed his eyes. He felt a myriad of thoughts in his mind.

This feeling was very strange.

It was an indescribable experience.

It seemed that after leaving the Fantasy Forest, his body had undergone some changes.

He had become more sensitive to his surroundings?

This feeling was very subtle.

But Klein was certain that it was a very good feeling.

Suddenly, Klein realized that a ring had appeared on his hand!

It was a blue purple ring.

"Did she give it to me?"

The first thing that came to Klein's mind was the Queen.

That's right, it must be her!

The Queen's cold expression instantly appeared in Klein's mind.

'What does this fellow mean by suddenly giving me a ring?'

Klein was somewhat puzzled.

'What's the use of this ring?'

'Could it be something like the Fire Ring?'

Klein's brain began to guess rapidly.

However, this guess was meaningless.

Therefore, Klein decided to test it himself.

However, something embarrassing happened.

Klein realized that he couldn't use the ring's ability.

To be precise, Klein didn't find any use for the ring.

It was really too strange, really.

It was a particularly strange feeling.

'Could it be that there's something wrong with the way I use it?'

Klein was very curious.

Logically speaking, there shouldn't be anything wrong with the ring the Queen gave him.

It was also absolutely impossible that it was just an ordinary ring.

Therefore, Klein felt that he definitely didn't use the ring the right way.

However, how should he use the correct method of the ring?

The Queen didn't tell Klein at all before she left!

Klein even remembered that when he left, the Queen didn't even tell him how to use the necklace.

Back then, Klein was too eager to return to the catacombs world.

Therefore, he naturally didn't ask further.

However, Klein probably had an idea about the necklace.

Furthermore, the Queen had said that he would use it when the situation was extremely critical, so there was a problem.

The crux of the problem was that the necklace the Queen had given him.

Was it similar to a telepathic summoning?

Looking at the necklace in his hand, Klein fell into deep thought.

Klein hadn't carefully observed the necklace at the time.

This necklace was very beautiful.

It had a very nice shape.

The color was also very beautiful.

It felt very different when he held it in his hand.

It was as though there was a wonderful feeling that was constantly surging through his body.

'Perhaps when I summon the Queen, it would be similar to this method?'

Klein kept thinking about it in his mind and came to this conclusion.

'Forget it. There's no point in thinking about it now.'

Klein shook his head. What he needed to figure out now was the usage of the purple ring.

Klein had a feeling that if he could use the purple ring well, his strength would increase by a lot.

Looking at the purple ring in his hand, Klein's mind was constantly filled with new ideas.

'Why not give it a try?'

Klein got up from his bed.

He was in his room.

He entered the virtual practice room.

He closed his eyes.

Klein's nerves were connecting to the virtual practice room.

The virtual practice room was a new function of the system.

Klein had used it once before.

However, at that time, the function had only just been developed.

In short, it was a new function introduced in the catacombs world.

Its purpose was to provide everyone with a platform to practice actual combat or a venue for searching.

Klein came to the virtual practice room.

He chose his own room.

He began practicing.

By the way, in the world of the virtual practice room, although it was only in a virtual environment, everyone's equipment and skills in the real world outside could be perfectly replicated in this virtual world.

However, it wouldn't have any real impact on the real world.

Klein took out his purple ring.

He looked at the purple ring.

Klein tried to sense it.

The feeling Klein had when he used the Fire Ring, he wanted to try replicating it on the purple ring.

However, it still didn't seem to work.

Could it be that this purple ring was really just an ornament?

Klein was rendered speechless.

He had tried all sorts of methods.

Why didn't it work?

Could it be that his level wasn't high enough?

Or was there another problem?

Klein's mind was momentarily at a loss.

However, one thing Klein was sure of was that he knew very well.

He had entered a very strange state.

That's right.

When Klein reacted, he realized that he had entered a very strange realm.

This realm was different from the virtual and real world he was in.

It was very hallucinatory.

Withdraw!

This thought suddenly appeared in Klein's mind

Soon, Klein returned to the environment of the virtual world.

Did I just unconsciously use the ring's true strength?

Klein suddenly realized.

Could it be that the ring's ability was similar to bringing a person's five senses into a hallucinatory world?

It was an offensive technique that was similar to illusions?

With this in mind, Klein suddenly felt a lot more enlightened.

This was a technique that was similar to an attack!

A mental attack!

When dealing with a particularly difficult opponent, such as when physical attacks or magic attacks were ineffective, he could try using a mental attack!

Sometimes, a mental attack was even more powerful than a physical attack!

As long as he attacked the opponent's spirit, there was a high chance that the opponent would lose his original strength.

He had entered a strange circle.

Wasn't this a new way of thinking?

With this in mind, Klein instantly became excited and began the test!
