The appearance of the three solid planets changed dramatically in an instant, countless buildings rose out of thin air, Pimi factories sprung up like mushrooms after a rain, and spaceports were built in the planets' geostationary orbits.

On many poor moons, countless mining facilities erode their flesh like black holes, converting matter into energy, and then through advanced production technology, directly converting energy into the required equipment, further expanding the number of industrial equipment.

In the vicinity of the star, countless warships have sounded the horn of landing, and the overwhelming membrane is pulled out of the body of the battleship, from the point to the line, and then from the line to the surface, quickly binding the corona, engulfing the ejected material, absorbing heat and radiation, and drawing energy from the body of the star in all directions.

Like gods, the dragon civilization can easily create things out of thin air, and in a short period of time, they can claim moons, planets, and even stars as their own, dedicating all their strength to civilization.

With the basic industrial equipment and energy infrastructure largely completed in a day, the main task is to build the framework of a commercial star system and divide it in an orderly manner.

With the information of the Fog Cloud Civilization and the Sky Breaking Civilization, the Dragon Teng Civilization has done a good job in this regard. The first layer is based on three solid planets, and the main commercial area is constructed, which is mainly responsible for the equal commercial exchange of various civilizations and the sale of some advanced technologies and resources; The second layer is based on the gaseous planet to build a vast supply area, where civilizations in need can supply and adjust as long as they deliver certain resources or provide some equivalent items and technologies; Since there are only four planets in the star system, after consideration by the senior management of the Seventh Fleet, the third layer as a security, alert, and ship berthing is located in the huge space of the gaseous planet soles, and relying on a large number of asteroids, countless spaceports and defense facilities have been built.

The construction period of the entire commercial star system should be about half a year, and after about half a year, it can start business, and then the Longteng civilization will use the space information transmission system to publicize the surrounding civilizations and radiate its influence.

In this half year, a small fleet commander like Edward can finally breathe a sigh of relief and rest for a while. This kind of basic engineering construction is generally handled by AI throughout the process, and at most some people from the Ministry of Information will regulate and control it, so it is completely easy to achieve a watertight realm.

As for the captains of some small warships, transport ships, and landing ships, their tasks are relatively heavy, after all, they need to cooperate with the AI's orders at any time to complete one task after another.

Commercial Star System 11 is just a microcosm of the Dragon Civilization Seed Project, and one after another, a total of seventeen commercial star systems have been established within a range of five hundred light years.

Regardless of what happened behind the scenes, at least on the surface, the Dragon Civilization tried to form a huge and benevolent business empire by dispersing its forces to build a commercial star system, seeking benefits for all the surrounding civilizations and showing its broad mind.

It took about a hundred years for the reputation of the Dragon Civilizations to finally blow out. On the territory of the Dragon Teng Civilization, in addition to the Void Breaking Civilization, there are three fourth-level civilizations that trade with the Dragon Teng Civilization.

Among them, there is even the two-headed dwarf civilization that forced the Dragon Teng civilization to leave the Noodle Star in the first place. After many years, the Dragon Civilization has finally made a comeback, reoccupied the Noodle Galaxy, and transformed it into a livable, beautiful, and free commercial star system, where the Dragon Civilization and the Two-Headed Dwarf Civilization have traded and communicated, but their attitudes are very different from those of more than two hundred years ago.

The current Dragon Teng civilization showed an inclusive attitude, which was a confident posture supported by strength, and the two-headed dwarf civilization did not dare to show the slightest arrogance, and respectfully completed the transaction according to the standard.

In addition to the fourth-level civilization, there are eleven third-level civilizations and four second-level civilizations that have visited the commercial star system of the Dragon Teng civilization, however, the scale of their visits is unparalleled.

Although the second-level civilization has completed the fourth industrial revolution and obtained the initial interstellar navigation ability, their endurance and speed are problematic, and only the second-level civilization that is very close to the commercial star system can visit the dragon civilization.

This also affects the scale of visits by second-level civilizations, and their visiting warships are generally smaller, but most of them are large warships to show their goodwill and sincerity.

As for the third-level civilizations, they have stronger interstellar navigation capabilities, stronger endurance, and larger range of activities, so the number of third-level civilizations visiting commercial star systems is relatively large.

Of course, no matter what kind of civilization it is, the Dragon Teng civilization treats everyone equally, and various commercial star systems frantically search for the genes of various lifeforms, and even obtain a lot of living organisms.

What's more, a second-level civilization did not hesitate to pay ten scientists, fifty soldiers, and a full set of gene pools in exchange for the purchase of particle weapons and particle stream protection layer technology.

Of course, the Dragon Civilization has always maintained an attitude of not refusing to compromise, as long as the visiting civilization can provide enough bargaining chips, then almost any technology can be sold.

It is precisely this attitude of putting interests first that has won the favor of all civilizations. After all, this kind of mercenary businessman who seems to be not mixed with other emotions is the best partner to work with.

However, behind the prosperity lies a crisis, the high-end technology field of the dragon civilization has not been broken through, the development of string theory is still slow, and the extra dimension is only on the verge of neutrino and proton collision......

Liu Wei knows very well that in the universe, scientific research determines the long-term upper limit of civilization, and technological research determines the short-term upper limit of civilization, and at the same time, science acts on technology.

Just like the theory of relativity and quantum mechanics in the twentieth century, the knowledge of that time is still exuding residual heat even now, and the dragon civilization can still get a lot of technology from it.

Although there has been no breakthrough in string theory for a long time, a large number of researchers have focused on quantum mechanics and this scientific theory that runs through the dragon civilization.

Quantum mechanics is related to string theory, and starting from it may help to unravel the mystery of extra dimensions.

However, even if the direction of efforts is found, the breakthrough of specific scientific theories will take hundreds of years.

Scientific theories are like a huge mountain, the higher you climb, the more difficult it becomes, the more effort you have to expend, and the more difficulties you have to overcome. At the same time, these theories are like pyramids, the higher you go, the fewer they may be, but those theories will be more high-end, simpler, and more terrifying.

This process of exploring theories must be experienced, but in the face of the Dragon Teng civilization, this process still takes too long, and the Divine War may completely involve it at any time, and no one can stay out of it.
