The fluorescence stretches, hundreds of millions of kilometers away as if it is a band of light, dotted with stars and incomparably bright.

Wanxing Cloud City, as the name suggests.

Although it is not composed of tens of thousands of stars, it is composed of tens of thousands of huge space cities of different styles.

In this primordial open and lonely star field, they were stunned to form such a super-large starry sky city full of vitality.

"There are more than 20,000 different civilizations here, everyone has their own territory, each civilization has its own space city, and the main purpose of coming here is to exchange and trade with each other, learn from each other's advanced cultures, and take what they ......need for trade."

Xing Ling became serious without smiling, and introduced Qin Tian without hurrying or slowing down.

Seeing the space cities in the distance that glowed like countless fireflies, Qin Tian really felt that the universe was really vast and boundless, and it was really too big.

The most rare and valuable thing is that all the advanced civilizations gathered here are level 2 and above, if all the human civilizations in the universe are gathered, I am afraid that there will be more of them, and if you add other types of civilizations, such as insects, silicon-based classes, etc., there are absolutely countless of them.

After a brief introduction, Xing Ling said: "Let's also start building our own space city, there is a customary rule in Wanxing Cloud City, that is, first come, first come, first come, everyone will never have war conflicts with each other, and they will act with each other in the principle of fairness and freedom!"

"In addition, for each other's safety, the distance between each space city should be at least 300,000 kilometers, and the collision avoidance system should be turned on around the clock so that passing starships will not collide. ”

After Xing Ling's concise reminder, Qin Tian ordered the fleet to start construction operations.

Thanks to the fact that in the former Garan Empire, which accounted for a lot of mineral galaxies, Qin Tian's construction capacity was greatly improved, and this time he not only brought a lot of skilled and powerful interstellar warships, but also a number of large interstellar cargo ships, supply ships, etc.

Thanks to the fact that there is no gravity in space, no matter how large the structural parts and frame components are, they can be gently dragged away by the engineering robot, which looks like 'ants pushing elephants'.

Soon, millions of tons of materials began to rapidly build the structural framework of the space city at a speed that was almost visible to the naked eye, thanks to the joint efforts of a large number of engineering robots and space flight machines.

In order for space cities to operate in space for a long time, gravity and light are indispensable.

Weile Technology and Weile Aerospace Technology jointly tackled key technical problems and designed the 'Sky Ring' city, which has a very sci-fi sense of design, and it is composed of eight huge rings that rotate non-stop.

Each modularly built ring, which is up to one kilometer wide and 10,000 kilometers in diameter, rotates at a certain rate, and when the eight rings rotate, it will rotate like a sphere, so that a constant gravity is generated.

In addition, in the center of the rotation of many rings, there is an artificial sun that is magnetically constrained and constantly fuses to produce light heat and a certain amount of radiation, which will provide constant light and heat for all the rings, so that the animals, plants and humans in the ring can enjoy sunbathing.

The most important thing is that each ring is a relatively closed ecological chain, with enough space for living activities, and the inner ring of the ring is used for residence, commerce, scientific research, production, etc., and the dark side of the outer ring is a variety of reconnaissance and defense facilities, port berthing facilities, etc.

Such a 'self-rotating' space city has an extremely large capacity and defense capacity, even if it encounters a strong enemy invasion, each of its modular rings can also be automatically freed, and the clamshell-type protective cover placed on the back will automatically close, and they will soon become a spaceship with autonomous navigation ability to escape.

Even if there is no invasion of a strong enemy, if it encounters a strong electromagnetic storm, such as a ray storm when a supernova erupts, these clamshell protective covers can also close the inner ring, and at that time, the entire 'Heavenly Ring' city will be like eight super huge iron rings rotating together like a rolling ball, shielding protection and self-rotating magnetic field constraints, and the ability to resist radiation impact is super strong.

The design of the Sky Ring City won the Weile Group's Annual Science and Technology Progress Award, and it was originally planned to build one on the other side of the earth, but because each country has its own space cities of different sizes, such an expensive to build and a super space city with strong capacity to build is estimated to not be able to absorb enough interstellar immigrants.

Therefore, Qin Tian simply built it in Wanxing Cloud City, and Tianhuan City will serve as the base of human civilization on the earth, taking root in the star field where many civilizations gather, and communicating and trading with major civilizations.

In the gray universe, countless aircraft are shuttling back and forth, countless intelligent robots are busy working, and standardized module units are being built rapidly.

This is a very magnificent and vast scene, and this is a very shocking scene.

In the command bridge of the Ares interstellar battleship, light and soft music sounded, and while enjoying the music, Qin Tian witnessed the whole process of building a super space city, Qin Tian had an indescribable enjoyment.

It's more enjoyable than seeing a building rise and a bridge across the sea.

At this moment, Qin Tian even felt that all planets were so far away, and only the miracle of space architecture that he witnessed with his own eyes could touch the depths of the star spirit.

Xing Ling stood by the porthole, standing with his hands in his hands and looking out at the Heavenly Ring City.

"Human beings are the most amazing species in the entire universe! Unbridled imagination, unparalleled creativity, as long as the technology is a little satisfied, you can create one miracle after another!"

Xingling's voice is no longer flamboyant, and it seems to have a feeling of vicissitudes of life that an old monk has settled.

Qin Tian chuckled and said, "So, is your Taihao civilization also a human civilization?"

Xing Ling snorted coldly: "Don't take my words, the Taihao civilization is a secret that you can't understand yet, wait until you break through to the level of space dimensional civilization!"

Qin Tian didn't say anything more.

According to what Xingling said before, whether it is a primitive civilization of slash-and-burn cultivation or an interstellar civilization that shuttles through galaxies today, they are actually civilizations in the four-dimensional space, and the length, width and height of the world they know are developing and evolving along the time axis.

The four-dimensional space is the most ubiquitous in the universe and the largest number of civilizations, but the universe is a multi-dimensional and multi-dimensional intertwined mixture, but there are also five-dimensional space civilizations and six-dimensional ...... But the Taihao civilization is a civilization of the first few dimensions, how strong it is, Qin Tian can't ask the answer at all.

Anyway, a high-dimensional civilization dealing with a low-dimensional civilization is equivalent to a person stepping on an ant, and the dimensionality reduction blow is definitely crushing and destructive, but they disdain to torture and kill a low-dimensional civilization, just like humans don't look for ants everywhere and then trample it to death.

Qin Tian felt that the Star Spirit was a 'chess piece' deliberately sent to the human beings on Earth by the Taihao Civilization that belonged to the high-dimensional space civilization, because it had said before that helping Qin Tian was an investment.

As for Taihao Civilization's investment in Qin Tian, what is the purpose and what the return is, I can't guess it for the time being.

And the so-called Wanxing Cloud City, in fact, the most fundamental reason for its existence is that after the first-level civilization reaches the top, it will encounter scientific research bottlenecks, and further 'upgrade resistance' will be particularly large.

After all, to change from a four-dimensional civilization to a five-dimensional civilization, it is necessary to increase the cognition of one dimension, which will mean to comprehend the rules of space, the original physical knowledge system to undergo earth-shaking changes, and to establish a new scientific system.

Therefore, the major civilizations have come here to exchange trade and learn from each other, whether it is for the purpose of entering the five-dimensional space civilization or not, they all want to make their strength go further and raise their scientific research level to a higher level.

But obviously, hundreds of thousands of years of history have passed, and there is no civilization in Myriad Nebula City that has broken through.

The star spirit has been hidden deeply, it is unwilling to say anything, and Qin Tian is too lazy to ask.

The construction speed of the Tianhuan City is very fast, as the so-called 'one leaf knows the autumn', and its design and construction level is enough to reflect the scientific and technological strength of the earth's human civilization.

The layman looks at the bustle, and the insider looks at the doorway.

Some civilizations that have been in Myriad Cloud City for many years have of course discovered 'newcomers' long ago.

After observing for a while, a nearby space city sent a friendly signal and sent a diplomatic ship.

According to the rules of Wanxing Cloud City, if different civilizations want to communicate with each other, they will use an agreed cosmic language, which is concise and concise and will not produce ambiguity, avoid direct communication with each other, and will cause ambiguity due to different cultural habits and thinking angles.

Moreover, the initial communication is generally not encrypted, so that the other party can quickly decipher, and after getting acquainted with it in the future, the two parties can agree on the communication method and frequency band for the sake of privacy, but basically they use cosmology as a medium.

However, when Qin Tian saw the compiled text, he couldn't help but raise his eyebrows.

"Atlantean civilization? Damn, this ...... Is this Nima mistranslated? This is one of several prehistoric civilizations that have been rumored to have appeared on Earth but have mysteriously disappeared!"

Qin Tian immediately looked at the situational awareness interface, the diplomatic ship of the Atlantis civilization, the silver-white flying ship that looked like an elongated droplet, was quietly waiting in the safe neutral zone 300,000 kilometers away......
