Yuan Haochen was still sitting in the corner, and he took a deep breath.

Fresh and refreshing, refreshing, there is a familiar fragrance in the forest after the rain.

This surprised Yuan Haochen.

He tilted his head, looked at the top of the labyrinth's passage, and slowly closed his eyes.

Some familiar images began to appear in my mind.

A little boy was sitting on a boulder by the waterhole of the Sun Moon Creek in his hometown, his feet barefoot submerged in the water. There seemed to be a cold feeling that went straight to the depths of my mind, and when I looked up at the stars in the sky, everything became quiet.

Yuan Haochen's mind began to return to calm.

He seemed to feel the gurgling stream, and the mist was slowly fluttering and dancing on the stream, changing his body from time to time. The fresh air after the rain and the smell of clear stream water instantly made him escape from his anxiety and restlessness.

"With such suitable living conditions, it can be seen that the Creator is indeed kind."

"Don't worry too much, it's just a test."

"I must crack the secret of this labyrinth as soon as possible!"

Yuan Haochen breathed in the fresh and cold air, and put his thoughts in the vast world, no longer anxious, no longer worried, no longer hesitant......

"We'd love to share with you some of the science and technology we're proud of. But only if you pass the test we have left behind. If you fail to pass the labyrinth, then the information we leave behind will be meaningless to you. ”

Yuan Chen silently repeated the words of the Creator.

"From the written messages, it can be felt that the Creator is willing to share his science and technology with other cosmic civilizations." Yuan Haochen began to figure out the written message left by the creator, "One thing is for sure, their original intention in leaving the labyrinth was not to make things difficult for those who came after them. Just to test our level of scientific cognition. ”

"Well, the secret behind this labyrinth must have something to do with some scientific theory!"

Yuan Haochen still closed his eyes, leaning against the wall, thinking to himself.

"And these scientific theories should be relatively advanced and extraordinary."

"So, what exactly is hidden in the depths of the labyrinth?"

"Hey......"

Yuan Haochen let out a long sigh, although his brain was running at high speed, he didn't analyze any valuable information.

[We have already given the hints that should be given.] Finally, good luck to you guys! 】

"These are the last words that the Creator has ever spoken."

"What would be the hint?"

Yuan began to break down the entire process of exploring the ruins in detail.

"Although it took us a whole month and countless trips back and forth to break through the passage that had been frozen for billions of years. However, this stage should not be associated with the prompting given by the Creator. Yuan Haochen judged in his heart.

"Then we went into the underground space. Passed through a two-dimensional labyrinth of extreme retardation......"

"Then I arrived at the entrance to this perverted labyrinth and found the message left by the Creator."

"What the hell is the hint!?"

There was no special indication in the text message left by the creator, and Yuan Haochen had already considered it countless times.

He even tried to analyze whether there was a special code hidden in the text, but in the end he found nothing.

"Otherwise, it's that retarded two-dimensional labyrinth!" Yuan Haochen pondered, "But this labyrinth is indeed too shallow, almost at a glance, and the structure is extremely simple. ”

"What kind of hints are hidden in this mentally retarded labyrinth?"

Yuan Haochen has the ability to never forget, and he has already walked this mentally handicapped labyrinth countless times in his mind.

......

Another ten hours passed.

Yuan Haochen still found nothing.

He just sat in the corner of the labyrinth with a blank gaze, motionless.

Forget the tiredness, forget the hunger......

Only the pupils were occasionally constricted, indicating that his brain was still running rapidly.

Since encountering that strange meteorite in the waterhole and gaining extraordinary memory, observation and thinking abilities, Yuan Haochen has not been so helpless for a long time.

At this moment, he felt that he had become a complete scumbag again, just like the boy who once sat by the waterhole and sighed, looking up at the starry sky, constantly lamenting his insignificance and ignorance.

"Compared to the vast universe, how small and ignorant we are, like an ant......" Yuan Haochen sighed secretly.

"Boom~~"

Suddenly, Yuan Haochen's brain seemed to be hit again.

"Suddenly~"

The next moment, Yuan Haochen stood up suddenly, and muttered to himself with extreme excitement: "We are small, just like ants, our vision is limited!" ”

At that moment, Yuan Haochen seemed to have caught a hint of inspiration, and then he held on to it firmly!

"Wrong, I've always thought wrong, the hint given by the Creator is so obvious!"

"I know the secret of the labyrinth!"

Yuan Haochen's whole person suddenly glowed with infinite brilliance, and his eyes burst out with wisdom again.

The intricate labyrinthine passages began to line up in his mind again.

Unfortunately, no one could see this magical image through his brain.

Yuan Haochen's brain is like a vast cosmic space, and every corner of the labyrinth, every three-way road, and every intersection are connected one by one like stars in the universe into an extremely complex spatial pattern.

And this spatial pattern is unimaginable to ordinary people, it only exists in geometric logic, without the help of special models, it is simply incomprehensible to human beings.

"Yes, it's the four-dimensional space labyrinth!!"

"There is no exit to the labyrinth, and the scientific and technological information should be in the core area of the labyrinth!"

After half an hour of brain-burning thinking, Yuan Haochen finally mastered all the secrets of the labyrinth.

(Note that it is not a four-dimensional space-time, four-dimensional space is a pure spatial scale, and four-dimensional space-time refers to three-dimensional space plus one-dimensional time, which will be covered later.) ）

We live in a three-dimensional space, and there are three dimensions in this world, namely length, width, and depth (height), and if you add another spatial dimension to these three dimensions, then it will form a four-dimensional space.

How do I add another spatial dimension?

Just as two-dimensional beings cannot understand three-dimensional space, we also have difficulty understanding the true four-dimensional space.

Human beings live in three-dimensional space, and we can only control three directions, which are length, width, and depth (height).

[The 19th-century Swiss geometrician Ludwig (Ludwigschlfli) was the first person to use geometry to solve the mysteries of the four-dimensional world. If you are interested, you can watch this video, /w_, it will lead you into the magical four-dimensional space, very, very brain-burning. 】

To put it simply, the zero dimension is a point, the first dimension is a line, the second dimension is a surface, the third dimension is a body, the point motion is a line, the line motion is a surface, and the surface motion is a body, all of which can be understood.

Four-dimensional space, on the other hand, is a new structure composed of multiple three-dimensional spatial structures.

Imagine that!

When a two-dimensional object (a piece of paper) crosses a one-dimensional space (a line) in parallel, it behaves as a line segment, and the one-dimensional creature can only see one line at most (if the paper is not parallel to the line, the one-dimensional creature can only see one point).

When a three-dimensional object (such as a sphere) passes perpendicularly through a two-dimensional space (a piece of paper), it appears as a continuously changing plane, and the two-dimensional creature can only see a flat figure of a circle at most (if the sphere is traversal along the paper, the two-dimensional creature can only see one line).

Then when a four-dimensional object passes through the three-dimensional space (our world), it will eventually appear as a three-dimensional body with continuous changes, because our latitude is relatively high, and we can use lines and planes to simulate a "three-dimensional image".

And this "three-dimensional image" is a maze structure diagram simulated by Hara Chen, Smith and Lynn using a detector.

However, this diagram is incorrect, it is just a projection of a four-dimensional object in three-dimensional space. It's like a ball projected on a wall, just a flat circle.

When Yuan and Smith enter the labyrinth of four-dimensional space, they will fall into each different three-dimensional space entity in the four-dimensional space, and then completely lost.

Human beings do not have the vision of four-dimensional space, and in the fourth dimension of space, we are like a blind person.

Therefore, we cannot see through the four-dimensional labyrinth, and even relying on imagination is a difficult thing.

It's like if we pick up a piece of food in front of an ant, the ant will just disappear out of thin air.

We can make another analogy using two-dimensional space: suppose there are some flat-slipped people living in two-dimensional space, and they only have the concept of a plane. If we want to lock up a two-dimensional flattened person, we just need to draw a circle around him with a line, so that within the confines of the two-dimensional space, he will not be able to get out of the circle anyway.

This four-dimensional space labyrinth is "a circle", which firmly locks up human beings who do not have a four-dimensional space vision! (To be continued.) )
