"Is there anything that can be used?"

Lu Ban asked Teacher Feng Yu.

"It's not good to be too simple and broad. For example, if the clothes you are wearing are black, such cognition will be easily confused."

Feng Yu gave an example.

"Also, it's best not to use concepts to interpret concepts. For example, if a piece of clothing is black, black is a color that needs to be defined. If in your cognition, black has become another color, then even if something abnormal occurs, you won't notice it."

“It’s so complicated.”

Lu Ban said.

Qin Tiantian had already eaten and drunk his fill, and fell asleep on the sofa, carefree and unaware that the three people around him were discussing something of great importance.

“It’s not that complicated.”

Feng Yu glanced at Qin Tiantian who was sleeping soundly, and the Corgi who was sleeping in Qin Tiantian's arms.

"Cognitive impairment does not rewrite the entire world, but it will change the cognition of you and the people around you. Therefore, this change will inevitably leave traces and a sense of disharmony."

"Just like financial records and company reports, as long as you investigate carefully, you will find something wrong and realize that your cognition is confused."

"This amusement park can cause people to go missing, and people around them won't be able to detect it for a short period of time after they disappear. However, the scope of its impact is limited. It can be assumed that it can only affect people who enter the amusement park, causing their existence to be erased from the consciousness of others, but the things that have been recorded before cannot be changed."

After hearing Feng Yu's words, Xiya probably understood a little bit.

"Is this something like memory manipulation?"

There are similar things in the magic of the Kingdom of Night, but ordinary wizards cannot access them and they are considered taboo spells.

"You can think of it that way about this amusement park."

Feng Yu nodded.

Human cognition can be roughly divided into two types: one is instinctive cognition and unconditional reflex, and the other is cognition derived from memory.

Cognition derived from memory is easy to understand. It is the cognition formed through learning and contact with things, such as the cognition of colors and sounds. It can be said that most of the cognition that supports normal human activities is of this type, and it is also the most easily hindered.

If strange things tamper with memories, the corresponding cognition will change, and people will eventually get lost in it.

But instinctive cognition is difficult to change.

For example, soft or hard touch, cold and hot, pain, etc., these exist objectively and can be felt without definition. When cognitive impairment occurs, these feelings are difficult to confuse.

"So, we need to establish a benchmark anchor point, such as a hard chopstick. When the three of us are together, we can rely on touching the chopstick to find out whether we are suffering from cognitive impairment."

Feng Yu said.

"Any suggestions?"

Lu Ban thought about it and felt that there were a lot of references, but also not many.

"Why not just use it."

Feng Yu pointed at Qin Tiantian who was snoring on the sofa.

"?"

Lu Ban didn’t quite understand.

Does this mean that Qin Tiantian's IQ is not affected by human will, and she is still stupid regardless of the confusion in her cognition?

Or is it that even if everyone's cognition is hindered, they can still recognize the concept of steel plate at first sight?

"…I meant the dog."

Feng Yu had no choice but to add another sentence.

"How do you know what I'm thinking?"

Lu Ban was a little surprised.

"Because I put a tapeworm in your stomach."

Feng Yu answered as a matter of course.

"Ascaris? Are they delicious?"

When Xia heard the keyword "stomach", she immediately thought of food.

“It should be delicious.”

Lu Ban replied.

"Then I want to eat."

Xiaya looked at Feng Yu.

"...The hound is not affected by time and space and can travel through foreign lands. In short, even if it is impaired in cognition, it can return to its original state by traveling back in time, unless it is killed on the spot. A creature that can kill the hound instantly does not need to use means such as cognitive impairment."

Feng Yu decided to ignore the stupid remarks of these two people.

"So if we carry it with us, we can be reminded when we are experiencing cognitive impairment, such as having it shout in some way, that's enough."

“Good idea.”

There is nothing to fault about Lu Ban.

He felt that if he really encountered a situation of cognitive confusion, the worst that could happen was that he would sing another song to see whose pollution was stronger, but there was a possibility of accidentally hurting his teammates.

"Then we can find time to set off."

The three of them discussed it and took Xiya and Qin Tiantian to have a barbecue meal. On the morning of the third day, they took a car to the abandoned town.

The weather is very good today. The sky is gray and there is a thin fog over the Lingjiang River, which does not belong to this season. Under the dim light, the amusement park is looming on the river bank, exuding a gloomy and eerie atmosphere.

"I asked a blasting team to blow it up, but it didn't seem to have much effect."

Lu Ban pointed at the amusement park and said.

“…”

Feng Yu glanced at Lu Ban and didn't want to complain.

“Ouch!”

Laika shouted towards the amusement park, as if she sensed something.

"Do you want me to try it first?"

Xia thought about it and raised her hand, ready to release magic.

“You can give it a try.”

Lu Ban did not stop him.

I saw that there seemed to be some kind of power gathering in Xia's hands, and then burst out.

After waiting for a while, Feng Yu asked curiously.

"Missed?"

"No, let the magic fly for a while."

Shia said.

The next moment, the invisible explosive magic exploded in the amusement park, and the devastating force destroyed all the Ferris wheels and carousels.

However, a moment later, the damaged amusement park buildings returned to their original state and even started to operate and light up.

"It looks like it can't be physically destroyed."

Lu Ban thought.

The three men and the dog walked down the hillside and followed the road to the bank of Lingjiang River.

In January, Jiangcheng is quite cold. The weather forecast indicates that there might be snowfall after nightfall. The air by the river is damp and cold, making people shiver.

The dilapidated amusement park is right here.

The gate was rusty, the name of the amusement park was incomplete, and looking inside, it was a dilapidated scene, just like any other abandoned amusement park.

Suddenly, a gust of wind blew.

Lu Ban narrowed his eyes and waited until the fog was blown away by the wind, only to see that the amusement park had been completely renovated.

On the brand new arch, the words "Jiangcheng Happy Valley" look like they came from a factory. The equipment in the amusement park is also operating normally, emitting joyful music.

Lu Ban looked inside and saw that there were many tourists in the amusement park.

These tourists included men, women, young and old, and everyone had a happy smile on their face. Some were riding the carousel, some were queuing for the Ferris wheel, and some had just got off the roller coaster. It was just like a normal amusement park.

On the side, Lu Ban also saw a wide road that extended forward and seemed to be connected to a highway.

An SUV drove up the road and stopped in the empty parking lot outside the amusement park.

A family of three got out of the car.

"Why is there an amusement park here? Want to go and see it?"

The father of the family said, and it seemed as if only the amusement park was left in his eyes, with a somewhat ferocious expression.

"Yes, yes, yes!"

The little boy yelled and pulled his parents' hands towards the amusement park.

Lu Ban stopped the three people.

"This amusement park is closed now, you guys should go back."

He said.

"Closed? It's open fine, and there's no need to queue. Who are you kidding?"

The mother said.

“Not open for business.”

Lu Ban said, and then winked at Xia.

Xia nodded and immediately came behind the family of three.

One punch from each of them, knocking them all out.

"…I thought you had some elegant way, like fainting or something."

Lu Ban looked at Xia dragging the family of three back to their car and said in confusion.

"Although a wizard is someone who uses magic, he is not someone who is controlled by magic. Only those who flexibly use various techniques and methods instead of relying solely on magic are true spell users."

Xia spoke righteously.

What she meant was probably that fists were more useful than spells at times like this.

Or maybe she didn't have the corresponding spell to pray for today and could only use her fists.

Lu Ban felt that the latter was more likely.

"It seems that this weirdness uses this method to lure others into it, thereby restraining humans?"

He glanced at the magnificent gate.

"It's our turn now."

Three people and a dog arrived at the gate.
