"Mr. Chen, that Soka man is gone, should we go back too?"

Kafra's voice rang out.

"Alright, let's go!"

Chen Xin looked at Cavram who was following him, and couldn't help but shake his head, although Cavram usually performs well, but when it comes to the critical moment, this guy is still a little unable to get on the stage.

It's just that there aren't many trusted people around me right now, so I can only settle for the time being.

……

In the next month or so, Chen Xin lived in Dongchen Xing, and this time he sold such a large batch of golden crows, and there were many people who monitored him, in addition to the dark market, he also became a sweet spot in the eyes of many silicon-based civilizations.

Of course, as long as he doesn't leave the Dark Market, no one will trouble him.

After all, on the bright side, the dark market still needs to maintain its rules, otherwise it will be a mess long ago if it is sandwiched between the two major alliances.

Liya didn't come to find Chen Xin, her identity in the dark market is public, and any action will attract the attention of all parties, plus now Chen Xin has also become a point of attention for major forces, so the two can't meet in a short period of time.

On the side of the Blood Moon Civilization, they landed on a terrestrial planet almost 20 astronomical units away from Dongchen Star, and the steel hammer did not make any special discoveries except for monitoring that the other party had contact with the people of the Raccoon Civilization.

This is also helpless, after all, the steel hammer has only reached the level of a fourth-level civilization, and there is no way to listen to the other party's quantum communication without alarming the other party.

Speaking of which, we have to mention quantum communication.

The quantum communication mentioned here is different from the quantum communication on the earth, and the so-called quantum communication on the earth is only quantum confidential communication, which is only the most basic application of quantum communication.

True quantum communication refers to quantum over-distance interaction.

That is, there is a mysterious relationship between two entangled particles, and even if they are separated by the entire universe, the state of one particle changes, and the state of the other particle must also change, as if there is telepathy.

Quantum communication is one of the cornerstones of the Age of Discovery, without which interstellar astronautics would be a joke.

Many second-level civilizations have not been recognized as official cosmic civilizations by the two alliances because they have no way to create quantum communication systems.

Only when a third-level civilization has created a quantum communication system within ten light years will it be officially accepted into the two alliances.

As for the fourth-level civilization, their earth-based quantum communication system can cover hundreds to thousands of light-years.

Only a fifth-level civilization like the Tianqin civilization can create a river-level quantum communication system.

Unfortunately, the Blood Moon Civilization is just such a civilization.

However, Chen Xin was not too worried, since the Tianqin civilization knew about their existence in advance, he was not afraid of any storms they would make.

After all, the Lyra civilization is the closest fifth-level peak civilization to the No. 7 Dark Market in the carbon-based life alliance, and its influence in the No. 7 Dark Market is extremely powerful.

Dealing with the Blood Moon Civilization whose base camp is tens of thousands of light years away, even if there is a Raccoon Civilization on the side, it is no longer a problem.

During this time, Chen Xin has been immersed in research.

After so many years of coming out of the Tianqin civilization, although he has not been able to master all the technologies and culture of the Tianqin civilization, in the field of basic science, Chen Xin has almost digested all the technologies of the Tianqin civilization.

Especially in the field of mathematics or physics, even against the top scientists of the Tianqin civilization, Chen Xin is confident that he can surpass the other party.

During this time, Chen Xin has been thinking about the entry point of advancing to the sixth level civilization.

Although the steel hammer has long pointed out that the direction of the sixth-level civilization is dimensional technology, how to probe the technological tentacles into the spatial dimension field is still a huge problem.

The Lyra civilization can accumulate a huge amount of resources to keep trial and error, and then find the right path from it.

However, Chen Xin can only do it alone, so he can only think about the technical routes that Dimension Technology may achieve through the study of mathematics and physics.

Some time ago, Chen Xin returned to Dongchen Star and chatted with Gangyi about quantum communication technology and the over-distance interaction between two particles, which gave him a hint of inspiration.

He later gave an analogous model of conjecture.

Imagine a sedan with three mirrors. Looking through two of the rearview mirrors, two sedans were seen coming from behind. One is observed separately in each mirror. Both cars are the same color. However, the size, speed of movement, and direction of movement of the car are not the same. After observing for a long time, I gradually realized that the two cars seemed to know each other's existence. If a car rotates one angle clockwise, the other car must also rotate clockwise at another angle. When one car accelerates, the other must also accelerate.

After a long time, the two cars disappeared. But at the same time, through another mirror (transparent windshield), I suddenly saw another car of the same color, appearing diagonally in front of me. This means that the two cars you saw before are the ones in front of you now!

It turns out that the two cars before were actually different images of the same car. Although they appear in different locations (two mirrors), they are actually the same object.

Therefore, quantum entanglement and overdistance action are likely to be the mapping or projection of high-dimensional space-time in four-dimensional space-time.

Perhaps the essence of the problem is beyond imagination, but scientists have not yet found it.

It's as if no one thought at the time that gravity could be explained as a natural manifestation of the curvature of space-time.

It's like an ant living in a quasi-two-dimensional plane.

It saw a shadow on the ground, which became larger and smaller for a while, an elliptical for a while, a perfect circle for a while, and the trajectory was still relatively complex.

The ants worked hard to come up with a bunch of formulas to calculate the shadow, and they were able to accurately predict the shape, size, and position of the shadow at the next moment.

Later, the ants finally learned that the shadow was just a projection of a basketball under a street lamp, and the size and shape of the basketball had never changed!

After Chen Xin told Gangyi about his idea, Gangyi thought about it for a long time and thought that it was extremely feasible to study the spatial dimension in the field of quantum communication.

But there is no way to study Chen Xin next, whether it is experimental verification or theoretical calculation, it requires a huge amount of resources and countless top scientists to participate in it.

It is impossible for Chen Xin alone, or even human civilization, to conduct research on such a scale.

Chen Xin simply told Liya his thoughts, of course, he didn't say it directly, but just told the other party that he could use quantum communication technology as the entry point of dimensional technology, and maybe it could help the Tianqin civilization save time to advance to the sixth-level civilization.

Leah was overjoyed when she heard this, and after communicating with the leadership of the Tianqin civilization, she immediately set off a climax of research on quantum communication technology within the Tianqin civilization.
