Qingyang sat in the classroom, watching the students leave one by one.

In about ten minutes, the teaching building was empty.

Qingyang was relieved.

Sticking out his head to look, the black dog guarding the exit was nowhere to be seen.

The staircase has also been restored to its original appearance.

Qingyang quickly went downstairs.

The multimedia classroom is on the first floor, so you have to get out of the hallway before the weird staircase reappears.

"Hum~"

The text message appeared out of place, and Qingyang stopped suddenly.

SMS rules must be mastered at the first time.

[There are rats on campus, and rats are small animals with long tails and gray or black fur all over their bodies, so make sure all the rats you see look like this.]

If you see a rat with no tail or yellow fur, be careful. If it is safe to do so, kill it immediately with the help of any tool at your disposal, and throw its body into the hallway, where a passing black dog will take care of it.

If you happen to encounter a black dog passing by and don't take the body of the weasel away, don't hesitate to kill the black dog immediately. ]

Yellow rats? Be careful?

It's confusing, but it's too late to think about it.

I can only vaguely feel that the yellow mouse is by no means a good kind.

Exit the hallway and enter the hallway.

Unlike the hustle and bustle of the day, the corridors at night are dark and silent, and unusually deserted.

Despite the slight footsteps, the rustle of the soles of the shoes against the ground is still clear to the ears.

The sensor lamp that is still in the repair can only barely work, the light is flickering on and off, and the eyes are sour.

Qingyang felt a little furious in his heart, and couldn't help but speed up his pace.

walked around a corner, but stood on the spot.

I saw a mouse lying in the corner of the wall, motionless.

It has shiny yellow fur and is several times larger than an ordinary mouse.

Seeing Qingyang breaking in, the yellow squirrel actually stood up like a person.

The yellow hairs all over the body exploded directly, like sharp steel thorns.

A pair of scarlet eyes were wide-eyed, revealing a touch of human greed!

This is the yellow rat in the text message?

Qingyang felt cold in his hands and feet in an instant.

There was no time to escape, and the yellow squirrels were already flying in.

He subconsciously raised his hand in front of him and dodged to the sides.

The weasel brushed against its arm, its blade-like hair cutting several deep cuts.

Blood flowed down his arm in an instant.

Qingyang's complexion changed drastically.

If you hit it, I'm afraid you will be stabbed into a sieve in an instant!

Endured the sharp pain in his arm, and took advantage of the opportunity to pass by with the yellow rat.

Qingyang ran forward frantically.

Smelling the smell of blood, the yellow squirrel excitedly let out a "squeak" roar.

Follow behind and chase after you.

Seeing that the distance was shrinking, Qingyang was covered in cold sweat.

Luckily, the multimedia classroom is just a short distance ahead.

Qingyang gritted his teeth and accelerated to the limit.

At one point, he slammed his grip on the doorknob and slammed it into it.

Crashed into the classroom along the inertia, stumbled directly and fell to the ground.

He tried to close the door, but the weasel was already chasing him.

There was no way for him to escape!

Seeing the Grim Reaper approaching at a rapid pace, Qingyang's face was as pale as paper.

Fear and despair flooded over me.

At the last moment, a figure stepped forward and hit the weasel with a stick.

The yellow squirrel was hit hard in an instant and flew out upside down.

Lying on the ground convulsing constantly.

Qingyang looked up and saw that it was a middle-aged man in a neat suit and black boxy glasses.

What he was holding in his hand was an electric baton!

The man continued to smash one stick after another, and his attack was extremely ruthless.

After a few moments, the weasel kicked its legs and completely lost its breath.

The man was expressionless and expertly poked the body into the hallway.

Shut the door.

A moment later, a sudden burst of dog barking sounded outside the door.

Through the window, I saw a group of black dogs swarming up, frantically tearing the corpse into pieces and then taking it away.

There were large patches of blood on the ground, almost staining the hallway in front of the door.

Qingyang's heart was beating when he saw it.

The man was still expressionless, as if he hadn't seen Qingyang.

I returned to my desk on my own.

"Excuse me, are you the teacher on duty here?"

Qingyang didn't seem to have seen this person in his memory, so he asked tentatively.

But the man was like a deaf man, and he didn't react in the slightest.

Qingyang keenly noticed that the other party's eyes seemed to be dodging!

It's like he's deliberately ignoring his existence!

There's obviously something weird about this!

Qingyang didn't dare to ask again.

At this moment, the man suddenly took out two things.

It seems to be placed casually on the table.

A roll of bandages, a card.

Qingyang was stunned, and then he understood in his heart.

The man should be the teacher on duty and be able to help him.

But it seems impossible to talk to him.

Qingyang bandaged the wound on his hand.

Then he looked at the card.

32 is written on the front and a password is written on the back.

It's the computer's number and boot password!

Qingyang came to the computer No. 32.

Turn on the device and enter the password.

The next moment, the screen turns from black to blue.

A four-leaf clover logo appears in the center of the blue background.

The four-leaf clover shook slightly, and Qingyang stared at it tightly unconsciously.

The pupils are out of focus, and the eyes gradually drift away.

At one point, the image suddenly disappears.

It's pitch black.

Qingyang woke up in an instant and swallowed his saliva fiercely.

Only then did he realize that he had just been confused!

The four-leaf clover on the screen seems to have a seductive power, which makes people unconsciously immersed in it.

It's hard to imagine that there really is such a power to control people's hearts in the world.

But fortunately, the other party has no malicious intent, otherwise the consequences will be unimaginable.

"Hum~"

Qingyang was relieved, and the text message came again.

Qingyang saw that there were two unread text messages!

The last one was sent two hours ago!

Qingyang was suddenly startled and looked at the time.

12:25！

How so!

He went to self-study at 9:50 p.m., and it took no more than 20 minutes to get on the way here.

In other words, he spent at least more than two hours in the multimedia classroom!

But he clearly felt that it had been here for less than ten minutes.

How could it be...

Qingyang looked up, but suddenly found that there was an extra person around him!

He was so scared that he almost didn't sit still.

If you look closely, it's a beautiful girl.

Melon seed face, distant mountain eyebrows, waist-length long black hair tightly tied behind him. The lilac dress wraps around her delicate figure, exuding an intoxicating and feminine atmosphere.

She was sitting in front of her computer, her eyes fixed on the screen.

It was obviously pitch black, but she was extremely fascinated.

It's really weird.

Seeing this, Qingyang felt very puzzled.

However, he remembered the four-leaf clover he had seen earlier.

A flash of inspiration flashed in my head.

I figured out what I understood in an instant, and my eyes were shining!

It's because of a change in cognition!

Qingyang's eyes were full of excitement.

Whether it's the four-leaf clover you just saw, or the time difference that doesn't match.

It's all the result of a change in cognition.

This just confirms his previous conjecture!

What has changed is never reality, but his perception!

Cognitive errors do exist!
