Fei's arrival made Wu Jian a sigh of relief.

However, he then began to worry about the two taskers on the other road again.

He Shujun and Ding Yi have not yet come back...what's the matter? What difficulties did they encounter?

Or is it still not clear about the time limit of this nightmare, and the scene there has not been investigated clearly, so there is no hurry to come back?

Wu Jian couldn't help but feel a little worried, but he then left these thoughts behind.

In any case, after this round of nightmare is over, when the second round of nightmare begins, they must have a way to communicate with each other.

He settled down and told Fei and the others what he had found in the library.

Fei also talked about the issue on the space agency's side.

"so……"

They said in unison, and then looked at each other.

They realized that the other party had understood what had happened.

In the end, Fei's lips trembled, and he said with a smile and cry: "So, this is the end..."

First it was a madness that lasted for a year without knowing its source, and then it was a sudden catastrophe that fell from the beginning.

Therefore, they will lose everything, trapped in this gloomy narrow building, and will never be able to leave.

The unseen fingers were also trembling slightly, but he tried to suppress his fear and prevent others from discovering it.

He whispered: "After the end...what happened?" He muttered to himself, "Why did we enter the narrow building?"

Fei pays more attention to one other thing than this.

She said, "Did you find it?"

"what?"

"This nightmare." Fei murmured, "Why does this nightmare enter our field of vision? Why can we know the truth?"

"Because..." Wu Jian almost instinctively and without thinking about answering this question, but then he was stunned. After a while, he slowly said, "Because, the narrow-building resident returned from a higher level. !"

Yes, this nightmare is a nightmare from a higher level.

And how many nightmares are there at higher levels?

neither knows. They don't even know how many floors there are in the narrow building.

Naturally, if this nightmare is at a higher level, no one will care.

They may enter this nightmare to explore and solve this nightmare because of some chance coincidence-or can't solve it.

But in any case, for Fei and Wujian, they may not enter this nightmare.

Because they have missed it. When they were on the floor where this nightmare was, they did not enter this nightmare.

After this, they are unlikely to return to that floor again, just to experience this nightmare.

They came back to the narrow building for the nightmare in the ruins, for the nightmare they possessed, with regard to the strange feature of "forgetting memories". Therefore, I went back to the bottom of the narrow building.

Later, they stayed at the bottom of the narrow building because of rumors one after another. The rest of the taskers are probably for the "ultimate nightmare", and they are for the "doom".

But no matter what, in the end, they still met this nightmare.

If this nightmare did not appear on the ground floor of the narrow building under the current situation, then I am afraid they would not turn their eyes to the past at all.

And even if Mu Jiashi had experienced this nightmare, even if he seemed to understand the truth symbolized by this nightmare.

But before Feihe Wujian suspected the residents of the narrow building, Mujia Shi also failed to tell the truth from Su Enya's hint.

Fei He Wu sees that he doesn't understand the end, and Mu Jiashi doesn't understand the residents of Zhailou.

But they came together by coincidence, and pieced together the truth.

One coincidence after another. So many coincidences have come together, is it true, can it be called a coincidence?

This is really incredible, and they have to wonder if there is an invisible hand pushing something behind this? But who can piece together such a coincidence?

There seemed to be a strong wind blowing in Fei's heart, making her original clear and definite thoughts instantly unclear.

She closed her eyes with a headache, and then said firmly: "Don't care about this for now. Let's solve the nightmare before us."

Wu Jian also nodded.

He faintly realized that just now, they seemed to have touched something they had never thought of before, a certain possibility.

Who can have monstrous power in the narrow building, enabling them to discover the truth among countless seemingly coincidental encounters?

NE.

He was startled when these two letters came to his mind.

He looked around instinctively and fearfully, for fear that his thoughts would be discovered.

But by whom?

By NE.

NE is the ruler of the entire narrow building. It can erase human memory, and it can control the human brain.

It is the invisible tyrant, the invisible hand. Only it can do that, only it.

But how is this possible? !

Suddenly swallowed with difficulty, and felt as if he had heard the fairy tales.

He shook his head, hurriedly put this incredible possibility behind him, and followed the rest of the taskers back to the library.

At this moment, Cuntou had convinced Xu Beijin and asked him to take them to the office on the fifth floor.

Since Fei and the others are back, naturally they will also go there together. The group of people walked toward the fifth floor in a mighty manner.

Xu Bei took the lead, and Ringo naturally followed him. Coupled with a few taskers and the student who followed them silently, the team was dragged and untidy, and everyone had their own thoughts.

When he saw Xu Beijin, Fei couldn't help but stunned.

Not long ago, when she saw the bookstore on the street, she was wondering if the bookstore owner on the ground floor of the narrow building would appear in this nightmare. Unexpectedly, he actually appeared, but he was not the owner of the bookstore.

He became a staff member of the library.

Even now, Fei is still very interested in Xu Beijin's nightmare. What nightmare would that be?

When Xu Bei was totally unwilling to open up his nightmare to the outside world, and Fei realized that the residents of Zhailou might be their kind, she could only put away her curiosity.

Moreover, Xu Beijin had originally reminded her that there was a problem with the residents of Zhailou.

However, Fei also had some speculations in his heart.

Bookstores, libraries... Coupled with Xu Bei's mysterious identity and vague hints, Fei Xin thought, he must have an extraordinarily important secret, right?

The bookstore owner on the ground floor of the narrow building... the bookstore... Fei looked at the countless books in the library, as well as the mysterious book that hides the secrets of other nightmares. And Xu Bei has an entire bookstore.

This nightmare contains elements of other nightmares.

Just now, Wu Jian also said in a particularly subtle tone that Xu Beijin also knew about their experience in the last nightmare, and mentioned the group of lunatics they met in the building in the last nightmare.

He knows those nightmares. Moreover, he also took the initiative to suggest to them the problems of the residents of the narrow buildings.

In addition, Fei had heard Mu Jiashi say that he had used a batch of drinks and exchanged a nightmare clue with Xu Beijin, which was their last nightmare.

Equivalent exchange...

Fei muttered the word.

She thought, obviously, Xu Beijin was kind to them, even though they hadn't communicated particularly carefully.

The ground floor of the narrow building... the ground floor...

Fei once thought, why the main brain, NE, must be on the highest floor of the narrow building?

She is also wondering now, is the main brain NE really the opposite of human beings?

But it seems that the invisible hand, the hand that pushes them to find the truth, belongs to someone who can do whatever they want in a narrow building...

And that could only be NE.

NE is helping them, and Xu Beijin is also helping them.

NE may not be on a higher level, but Xu Bei is on the bottom of the narrow building.

NE must have the clues to the nightmare, and Xu Bei has an entire bookstore.

And Xu Beijin never opened his nightmare to the outside world.

More importantly, the name.

Isn't that obvious?

NE, northend, the end of the north.

Xu Beijin...

Fei took a deep breath, his face was pale, and his mentality was shaky because of the suspicion that had arisen in his heart.

She knew there were many unreasonable things in this.

For example, why does NE help them?

For another example, Xu Beijin is obviously a human being, how could he be artificial intelligence?

For another example, if Xu Beijin is really NE and has goodwill towards human beings, then why hasn't he taken any action for so many years? Until now?

Fei couldn't figure out these things.

She lowered her head, smiled bitterly, and thought to herself, this might just be her wild thoughts.

NE, how could it be human?

Maybe everything is just coincidence.

Fei thought so.

She put aside the guess.

They came to the office on the fifth floor.

Xu Beijin took a key out of his pocket and opened the door to the fifth floor. They walked into the corridor on the fifth floor together.

Xu Beijin said: "I hope you don't read my colleague's items indiscriminately." Then, he smiled bitterly, "However, I'm afraid they won't be back here."

"What happened?" Fei asked almost subconsciously, "Apart from you, what about the other employees in the library?"

She realized that in the information that Umbrella told her, it seemed that there was no part about the other staff of the library at all.

She glanced at Wu Jian, and smiled with a guilty conscience.

But it's not too late to ask, it just so happened that they were still on the fifth floor.

Xu Beijin was silent for a moment, and did not answer this question immediately. Because……

He actually didn't know the answer to this question, he was sorting out the information that appeared in his mind and provided to him by the main brain NE.

However, this kind of pause is just right, enough to make the taskers' brains make up for some tragic past.

Afterwards, Xu Beijin said in a deep voice: "They are all crazy."

"Crazy?" Fei asked in surprise. She couldn't help but ask, "If you are crazy, shouldn't you continue to work in the library?"

"The library...is not the same." Xu Beijin said, "After the madness spread in human society, many people have changed...just like a museum. If it weren't for the insistence of the old curator, then I am afraid not. People are willing to stay in the museum and continue to work."

Regarding the museum, NE did not provide him with relevant information, but he saw the relevant situation through the live broadcast room, so he said it logically at this time.

For the taskers, this only makes his image more mysterious and unpredictable, as if he knows the nightmare situation well.

But in fact, he just cheated through the live broadcast system.

Fei asked slightly surprised: "Libraries, museums... are the original employees reluctant to work?"

"They seem to think that this kind of work is more abhorrent." Xu Beijin said, "I think it is meaningless. Not only themselves, but some employees also had to leave the library because of opposition from their families."

Doesn't make sense...?

Fei was silent.

She suddenly thought of the empty and deserted space building.

Indeed, at this moment, human society may not need to take the stars and seas seriously, treat past civilizations, and treat past history.

They are facing a more cruel reality. There are many things they need to do, but they don’t need to care about the past human civilization.

This is a troubled world.

Except for survival and struggle, everything else is meaningless.

Why does the level of civilization always regress after the troubled times?

This is a necessity that cannot be stated.

In silence, several taskers tacitly ignored this topic, scattered on the fifth floor of the library, and began to look for possible clues.

But it is obvious that there are no living people on the fifth floor.

After a while, Fei and Wujian joined together.

Unexpectedly, he said: "Could it be that there are only two living people in the library?"

Fei said, "It's not just people who are alive that can bring clues."

Wu Jian nodded.

At this time, a little bit of the head suddenly turned to them and said, "Look at this office!"

Several people gathered around one after another.

In the office here, most of the doors are open. They came to one of them, which seemed to be an ancient book research center, with a large number of ancient books and even bamboo slips stacked on the desk.

Wu Jian couldn't help asking in surprise: "How can such things be stacked here at random?"

"Because no one is working anymore."

They turned their heads and saw that it was a boy who looked like a student.

He said: “There is no one working here, and only Brother Xu staying here.” He pointed to Xu Beijin, “Originally, after the madness spread among us, the library planned to put some precious things here. Ancient books are transferred away.

"But before they could finish it, those staff members stopped coming one after another. Before they left, they messed up the library collection, saying something that was already useless...

"I came to the library as a part-time job last summer vacation. Later, my family was also... crazy, so I came to the library often, and there was nothing else to do anyway. I'll be with Brother Xu, if I have time. Just sort out the book.

"These books were originally taken out in different categories, but now I don't know where they should be placed, and I can't find someone who can come to receive them, so I have to pile them up here and organize them temporarily."

The taskers slowly understood.

They couldn't help what happened to the library. Besides, they care more about the truth of this nightmare than what happened here, rather than some books here.

The boy saw that they were indifferent, so he had to turn his gaze to Xu Beijin.

Xu Beijin shook his head gently.

Fei He Wu Jian, and Mu Jiashi, watching the eye contact between these two people, couldn't help thinking, are they acting according to the script?

After realizing the problems of the residents of the narrow buildings, they can no longer fully substituting into this nightmare, instead they always regard themselves and others as people in the play.

I don't know if this is a good thing or a bad thing.

They continued to explore on the fifth floor of the library.

Time passed bit by bit.

After a few minutes, Cuntou suddenly made a "hush" gesture, and he said, "Did you hear any sound?"

The taskers looked at each other.

They listened attentively, and vaguely heard a rustling noise in a certain office.

"That's..." Wu Jian hesitated for a moment, "Radio?"

When the tasker heard the rustle of the radio on the fifth floor of the library, Ding Yi and He Shujun were also on their way back to the library.

They just left the museum.

Originally, the old curator wanted to take them to visit again, but He Shujun left the museum smoothly because he was not feeling well and wanted to see a professional doctor.

Or maybe it was because they hadn't started the visit, so the old curator decided to let them leave.

When they left, they saw the van that the museum transferred the collections also driving out through the side door.

I don't know where it is going, maybe it is also a scene in the nightmare?

Ding Yi and He Shujun walked back quickly along the road where the bus drove them.

However, after walking for a while, they met an endless stream of lunatics. Not only does it make them feel sick and dizzy, but it also blocks their way and sometimes makes them have to detour.

At this time, He Shujun couldn't help but said helplessly: "How long do we have to walk before we can get back to the library?"

She realized at this moment, because it was a bus when it came, and the bus was moving faster and faster on the way back. Therefore, they seem to have greatly underestimated the distance of this road.

They walked for more than ten minutes and could not see the next stop of the bus, which is the art gallery, let alone their actual destination library.

He Shujun couldn't help but feel a little depressed.

She thought for a while, and said: "Why don't we investigate all the shops along the road, after all, when we went to the museum before, it was a bus, and we didn't pay attention to the surrounding situation at all."

Ding Yi said: "Okay, I have no opinion."

As a result, they slowed down even more and paid attention to the shops on the street.

Lots of lunatics.

Once he took a closer look, He Shujun couldn't help but sigh.

She probably knew what happened in this world. The doctor explained it to them, so that they could be more or less sure about this nightmare.

However, they did not really encounter those crazy humans along the way.

They go to the museum by bus, and the drivers and passengers on the bus, as well as the people in the museum, although crazy, are not particularly dangerous.

Their madness is controllable and non-destructive.

But what they encounter now is different.

He Shujun looked a little surprised and disgusted at the scene in the French window.

This is an educational institution. After class, middle school students will make up lessons and do problems.

Surprisingly, at this moment, it is still overcrowded.

Parents and children blocked the inside and most of them were waiting in line for tuition. Only a few lucky ones were able to enter the room and be educated by tutors.

There are floor-to-ceiling windows on both sides of that room, one facing the street outside and the other facing the waiting parents in the store.

The waiting parents and children looked at the people studying inside with jealous eyes.

There are not only students but also parents in that room. In this special tuition institution, parents also need to accompany the children while they are studying.

The purpose of the parent's accompany is not to let the child concentrate on studying, but...

He Shujun stared at that scene blankly, frowning.

She saw the parents stretched out their arms, and the thin blood vessels were fixed on their arms, and the small blood flow was drawn from their veins, and then gathered in a small bowl on the student desk.

The students all took the dipping pen, their faces calmly and attentively lowered their heads to write, and from time to time they looked and didn't look at the pen tip to dip in the blood of their parents, and then continued to write.

The parents looked at their children with satisfaction.

Although their faces are pale, tired and weak, they are proud of each other. Their children's homework also has their share of hard work.

He Shujun only felt that she was going to get goose bumps all over her body. The small bowls of bright red blood made her feel dizzy and painful. Her lips trembled, and she whispered: "Crazy? Crazy..."

Ding Yi lowered his eyes silently, not watching that scene.

He Shujun closed her eyes bitterly, stomped her feet vigorously, and hurried away from the window of this educational institution.

When Ding Yi caught up with her, He Shujun said to her, "It's crazy!"

Ding Yi said: "Such craziness seems to have something to do with their experience before they were not crazy."

He Shujun said: "My parents are not like this." She thought about it, and then said, "I am not like those crazy kids. Does this kind of madness really come from their original lives?"

Ding Yi smiled helplessly.

She realized that even though he was in the narrow building, He Shujun seemed to still retain a bit of cheerful personality that belonged to the peaceful period on earth.

It is hard to imagine how such a straightforward and kind-hearted young man would live in a place like a narrow building.

Or, life itself is such a tragic thing?

She did not answer He Shujun's question, and He Shujun did not ask any more.

They intend to keep going.

However, at this moment, they suddenly heard a dull and vague loud noise coming from a distance.

It must be the sound of something falling, collapsing or even exploding.

The two men looked up subconsciously, only to find that the sky in the distance was already drowsy. The originally blue sky was covered by black smoke, dust and messy debris.

Ding Yi was stunned, and subconsciously said: "Wh, what..."

She felt a shock wave, like a violent wind, knocking her down. She heard the sound of ping-pong-pong ping-pong-pong around her, as if a lot of things fell. She felt groggy before her eyes.

Then, she suddenly heard something...some kind of terrifying, indescribable muffled sound in her ears.

What?

Ding Yi turned his head almost subconsciously, and then his pupils shrank.

She couldn't forget the scene until the nightmare restarted. I am afraid, she will never forget that scene.

The huge stones hit from a distance completely buried He Shujun. The lively, young girl died silently in an instant. The blood flowing slowly came to Ding Yi's feet.
