Soon, an elderly man who was attempting suicide was found in the next space. A young man with curly hair next to him was desperately holding his leg and trying to save him, and when he saw someone else coming, he quickly shouted, "Come and help, help me save him." ”

After confirming that there was no danger, the detective man jumped into the room in a vigorous posture and rescued the elderly man who had attempted suicide with the thin man.

The elderly man who couldn't commit suicide sat on the wall of the room with blank eyes, and sighed: "Give up, everyone here will die, and no one will be able to unlock that code." ”

"What password?" Most of the people present asked this sentence at the same time.

But the old man just muttered to himself, and did not talk to the anxious crowd at all.

McLean and the detective man and the others obviously began to be impatient, and even tried to intimidate the elderly man through strong body movements, but everyone wanted to commit suicide just now, how could they be afraid of this little threat.

In the midst of the noise, a strange, transparent wall suddenly appeared in the space out of nothing, and it slowly moved.

The transparent wall was silent and invisible, and a terrifying change took place everywhere it passed—time accelerated! But it is difficult to tell with the naked eye, and where can people with different thoughts in the center of the room find this hidden crisis.

However, the clues left by this invisible wall are still difficult to escape Jin Zhan's perverted and powerful perception!

Although everyone was basically troubled by questions such as passwords from the mouth of the elderly man, Jin Zhan's multi-core processor-like brain shrouded perception in the entire space in real time while thinking.

With the appearance of the transparent wall, Jin Zhan suddenly felt a trace of abnormality, especially as time slowly passed, he found that the noisy voices of several people had changed significantly.

Specifically, it was as if there were many inaudible echoes. If it weren't for his current super thinking and reflex ability, he wouldn't be able to tell the difference at all.

After discovering the clues of the voice problem, Jin Zhan quickly became alert. Constantly changing angles and directions to capture the intensity and frequency phase of sound waves in all directions, after some analysis and comparison, he firmly locked the spearhead on the direction of the wall on the right-hand side.

The sound echo from this direction seems to be accelerating significantly! And as time goes by, this tendency to accelerate becomes more and more obvious.

It was as if a wall of time came from that direction, dividing the room into two different planes. To be precise, two regions in the same space have completely different time flow rates!!

Jin Zhan roughly located the location of the invisible wall of time through the calculation of the sound echoes of each wall in his brain. At the same time, the wall had shifted to the old man's suitcase.

In an instant, the box was full of cracks and looked dilapidated.

Obviously, this wall has the power of the rules of time, and the place it passes can instantly rewrite time!!

Jin Zhan suddenly interrupted the crowd with a loud voice, especially McLean, who was closest to the invisible wall. After the latter heard Jin Zhan's warning, he was shocked and immediately reflexively retreated.

After all, after experiencing two dream worlds, it is considered to be a quick response to the endless potential crises in them.

Under Jin Zhan's reminder, everyone also saw the amazing changes in the instantaneous aging of the invisible wall after passing through the items. McLean was even more apprehensive.

Seeing this scene, everyone gasped again and again, and just wanted to escape from this room quickly. Only the crazy old man behind him smiled strangely: "Everything is already doomed, come on." ”

The strange voice left an indelible shadow in the hearts of everyone who escaped from the room.

After escaping by luck, everyone couldn't help but think a little higher about Jin Zhan, a thin young man, and at the same time had a deep understanding of the hidden killing motives in this space.

The young curly-haired man who had been rescued in the room also began to explain to everyone: "The elderly man who died just now was a military colonel, and I was a programmer who wrote the code for him. ”

"He and I don't know why I came to this terrifying place for some reason, and the colonel seems to know a little bit about this space, so once he entered, he had no desire to escape."

"Wait." The trialist named Natasha interrupted the young man's words and asked, "What did the old colonel say just now that he couldn't find the password?" ”

"As soon as he entered, he was babbling to find his so-called password, but he didn't tell me the specifics. When I asked again and again, he only seemed to know about a USB drive or something. The curly-haired man replied.

As soon as the word "USB drive" came out, several people present had different reactions. Jin Zhan's observation is so keen, and he immediately captured Kate, a female white-collar worker who has the strongest reaction among a group of people.

For a moment, it seemed that her eyes were no longer as confused as they were when they met her just now. There is even a faint surprise written on the subtle smile that curls up at the corner of his mouth. Immediately pretended to be confused and helpless, harmless to humans and animals.

It seems that her lost memories have returned. But since she covered up the past so quickly, Jin Zhan felt that it was unlikely that he would get any information from her.

Seeing the glamorous Natasha chatting with him, the curly-haired young man seemed to have opened the conversation, and kept nagging there about his previous experiences, but everyone also got a lot of useful information from it.

Especially when he mentions that he once created and developed a game that is very similar to this cube, he used a combination of various parallel worlds, and this novel idea was immediately plagiarized by the military company.

The speaker has no intention, but the listener has the intention. Jin Zhan instantly captured the word parallel world. Because along the way, I have experienced a lot of space through repeated tossing and turning. As he entered every room, he left his mark.

And it seems that these labeled data simply cannot be adapted in the Rubik's Cube matrix built in his brain. With the method of 3D coordinate system, it is never possible to establish a reasonable position to match the situation in reality.

Could it be that each of these rooms is a parallel world?

Thinking of this, Jin Zhan also shared his thoughts with everyone, and McLean and the others also had some of the same doubts.

Because this ever-changing cube room has different rules. In particular, the terrifying speed of time can be changed, which has to make them wonder about the possibility of parallel space.

As he walked and talked, a prostrate corpse appeared in the next space, and the knife he was holding was still pointing at a nearby wall.

It is engraved with dense small letters, as well as the last few eye-catching numbers "60659".

The curly-haired little brother exclaimed, "Professor! I read that right, he was one of the greatest physicists of our time. ”

"Is this number some kind of code he solved?" Natasha was quick to blurt out a question.

Jin Zhan nodded approvingly, and his body had already come to the large list of characters to take a closer look.

The scribbled knife-engraved characters are clearly the derivation of some kind of formula. At first glance, it is difficult to guess the meaning of specific data and variables, so it is impossible to understand the meaning of the derivation process at once.

However, he found and believed that the professor's derivation seemed to use the axes of "X, Y, Z, W" four degrees of latitude.

This discovery caused an uproar in his mind, and it was no wonder that the model of the room just now was almost all wrong. According to the physics professor's derivation process, this space is obviously a four-dimensional hypercube structure.

For the high-dimensional space, even Jin Zhan's original level of science and technology in that era could only sigh. Because for human beings in three-dimensional space, it is difficult to imagine even the imagination of what kind of structure the four-dimensional space is, let alone explore and create.

And in this dream world, such a huge four-dimensional cube structure has been successfully constructed. It seems that in a sense, this dream world must be the product of a higher intelligent civilization. Some of them should be far ahead of his time.

"What four-dimensional space hypercube?" After hearing Jin Zhan's views, everyone present asked in confusion.

Even the two trialists from the post-era only had the simple concept of four-dimensional space in their minds, and no one had ever studied it seriously. After all, it's just too far from their lives.

Natasha asked Jin Zhan, "Does this four-dimensional space refer to the three-dimensional world and one dimension of time?" Isn't this also a good confirmation that the laws of time are different in different rooms in this world? ”

"No," Jin Zhan shook his head and said affirmatively, "It's not time, you're talking about four-dimensional space-time, not four-dimensional space." Four-dimensional space-time is actually the real world we live in, and four-dimensional space is a combination of countless three-dimensional spaces. ”

Natasha nodded as if she didn't understand, and humbly asked, "Well, Jin Zhan, can you give me a general explanation?" Perhaps this is the key to solving the mystery. ”

People are more or less good teachers, and in the face of Natasha's sincere advice, Jin Zhan also explained the principle of the four-dimensional space in simple terms.

"In fact, although the four-dimensional space is too far away from the space we are in to be unimaginable, it is not difficult to understand if we think about it step by step."

"Take this cube as an example, a one-dimensional line segment translates the distance of the edge along the vertical direction to form a two-dimensional plane square."

"A two-dimensional plane square forms a three-dimensional cube by translating the distance of the sides of the square along the direction of the vertical plane; A three-dimensional cube moves in the direction of perpendicular to six faces at the same time, forming a four-dimensional hypercube. ”

"Conversely, a two-dimensional square can be differentially cut to obtain a segment; Differential cutting of three-dimensional cubes can obtain two-dimensional square planes; ”

"So in the same way, a three-dimensional cube is a slice of a four-dimensional hypercube. The four-dimensional space is composed of countless such three-dimensional space slices. ”

McLean frowned, as if he was in deep thought.

Natasha quickly thought for a moment: "Then does the "60659" obtained by this physics professor mean that there are so many slices of three-dimensional space?" In other words, there are more than 60,000 parallel spaces here? ”

As Natasha's question came out, the rest of the people's hearts sank, and their hearts sank, and they wondered if there were really so many rooms, so when would they find that exit.

Jin Zhan's psychology immediately gave a negative answer, after all, the four-dimensional space cobbled together by more than 60,000 parallel worlds is a huge burden of computing resources for this dream world.

From the perspective of designing this dream world, there is no need to create so many parallel three-dimensional spaces. Since Jin Zhan didn't have a reasonable explanation for this number for the time being, he just shook his head lightly.
