He was very distressed for a two-dimensional space flat film man with only the concept of plane because he was firmly locked up by a circle drawn around him. If he could not break this circle, it seemed that he would not be able to get out of no matter what.

We in the three-dimensional space world shouted to him: "Hey, you just jump vertically! Isn't it easy to get out?"

However, he didn't know what to do, because he couldn't understand what the three-dimensional space world looked like.

Similarly, if a person in our world is locked in prison, he will definitely escape to a four-dimensional space. In mathematics, there is a direction we cannot point to, but we cannot perceive this direction.

Imagine that maybe at this moment, people in the four-dimensional space world are around us in the pattern of God's perspective, watching our every move.

The four-dimensional space in mathematics (and higher-dimensional space) is like a virtual machine, which can run various programs (you can study the properties of various geometric bodies in four-dimensional space).

However, it is difficult for people in the three-dimensional space world to understand what the four-dimensional space world looks like. Therefore, unless someone actually arrives at the four-dimensional space world and comes back to tell you, it is never possible for someone to describe the real situation of the four-dimensional space world.

In this test, the Creator used the maze in front of him to let Yuan Shichen have a preliminary understanding of the four-dimensional space.

"This is not a complete four-dimensional space!"

Yuan Shichen had already realized this. Otherwise, even if he had amazing brain power, it would never be possible to simulate the structure of the entire four-dimensional space maze in a short period of time.

"This is at most an independent four-dimensional space model, but this is already quite amazing!"

"The so-called prompt of the Creator is to use a two-dimensional maze to tell later generations that they should use God's perspective and use a higher spatial dimension to observe this maze."

"Thank you, for letting me master the relevant knowledge of four-dimensional space."

Yuan Shichen believed that being able to understand four-dimensional space must be the basis for understanding the science and technology left by the Creator.

Although the maze's explanation of four-dimensional space is still very basic, it is an enlightenment for later generations.

As the saying goes, the master leads the door and practices depends on the individual. The next path depends on the earth civilization itself.

"Go and rescue Smith first."

Yuan Shichen was sure that he was already very clear about the structure of the four-dimensional space maze. Therefore, based on the direction chosen by Smith before, he could calculate the approximate position of Smith's loss.

Half an hour later, Yuan Shichen found Smith with a frightened and frustrated look on the corner of an alley.

"O my God!"

The moment Smith saw Yuan Shichen, he collapsed instantly.

"What the hell is this? I thought I could never get out again!"

"Fortunately the air and temperature here are suitable for human survival, otherwise I would have seen God long ago!"

"Thank you for your hard work, Smith. Everything is over." Haraki Chan comforted.

He was also trapped in the maze for more than 20 hours, alone, without eating or drinking, and blindly rushing around like a headless fly, both physically and mentally, and suffered huge torture. Therefore, he was particularly able to understand Smith's mood at this time.

"What should I do? Next, this place is too weird. I ran and broke my legs and couldn't find the exit."

Smith finally calmed down.

"Don't worry, I already know what to do." Yuan Shichen patted Smith's shoulder and said confidently.

"That, that's great!!"

Smith heard that he could walk out of this damn maze, as if he had won a lottery prize, and his face was full of surprises.

"Let's go, let's get the science and technology left by the Creator first."

“Follow your instructions.”

Smith's eyes finally revealed the spirit that soldiers should have again

One hour later.

Harashi Chen and Smith finally arrived at the core area of ​​the entire four-dimensional space maze.

This is a hemispherical space, with a circular platform lying quietly in the center.

There is no trace of dust on the platform, even if it has experienced billions of years of loneliness.

There are two small diamond transparent crystal blocks that are embedded in a circular area in the center of the platform. The diamond transparent crystal blocks are reflecting charming brilliance under the light.

On the right side of the circular platform, there is also a diamond-shaped console.

"This should be a kind of laser working fluid memory." Yuan Naichen guessed that such a memory is not afraid of time. If it is not subjected to strong external forces, the information it stores will never be damaged.

"Then what we have worked so hard to find is inside?" Smith asked.

"It should be like this!"

"Look, there should have been three memory here!" Yuan Shichen was surprised to find that there was an empty groove in the circular area inlaid with diamond-shaped transparent crystal blocks. In the other two grooves, there were two diamond-shaped transparent crystal blocks with exactly the same appearance.

"Why is one piece missing?" Smith also became nervous.

"I don't know, let's take a look at the information left by the Creator first." Yuan Shichen said without comment.

Then, Yuan Shichen raised his right hand and patted it on the diamond-shaped console beside him.

"Buzz~buzz~"

There was also a burst of ethereal sound and fluctuations coming out. Yuan Hashichen and Smith began to wait patiently.

"Si~Si~"

Another red spectrum was emitted from one end of the console very quickly, and Yuan Shichen was swept from top to bottom.

This time, Yuan Shichen was mentally prepared and did not make any escape moves.

“Suddenly~Suddenly~”

After the red spectrum disappears, lines of text symbols begin to jump out of the display screen.

"Welcome to you again, the intelligent creature you have never met before."

Yuan Shichen began to interpret these words.

"I'm glad you passed the test."

"We still don't know where you came from and why you are here. If your scientific civilization is far superior to us, then the previous test may be just an extremely simple little game in your eyes. The proud science and technology we left behind may not be worth mentioning in your eyes. But we still hope to express our greetings to you in the future. This is regarded as a friendly exchange between us."

"If you spend some energy to get here, it means that your scientific civilization will not be too low at least, then the science and technology we left behind may have some reference value for you."
