Ruan Lin's consciousness returned to his body, and he wanted to take a look at the products related to science and technology, even if he didn't buy them, he could find some ideas for the future development of science and technology.

He clicked on the science and technology column, and the number of specific products was as many as 9,600! He was also amazed by the richness! Below the controllable fusion engine is the Basic Kinetic Energy and Laser Weapon Bundle, which costs 6,000 Enlightenment Points.

Ruan Lin had already scolded them silently 10,000 times in his heart, how dare this most basic thing be sold so expensive? Or is it bundled and sold, is it possible that some of the technology trees of wisdom and civilization are crooked to this extent?

Underneath is a technology that intrigues Ruan Lin: the Basic Ship Particle Barrier. This is the ship's exterior shield conceived in a science fiction movie.

The price is also impressive: 20,000 enlightenment points.

Kan Xi also noticed Ruan Lin's needs at this time: "Your civilization is really discerning!" This barrier can withstand the direct damage of most weapons! This is the means of protection that countless civilizations crave, which can ensure the safety of your civilization's voyage! If you buy now, we can reduce it to 16,000 Venus Points! ”

This is an advanced consumption trap, which always seduces Ruan Lin into it.

He had already begun to fantasize in his mind: as long as he had this technology, kinetic weapons would not be able to pose a threat to him, as long as the ship's engines were properly modified...

The next moment, Ruan Lin thought of the mirror countermeasure of the laser weapon again, and he woke up:

Yes, this kind of barrier increases the protection of ships by consuming energy, and the cost-effectiveness ratio is too low, and the energy consumption is too great. I have this extra amount of energy, I might as well equip a few more laser weapons, and attack will always be the most expensive option!

For large-scale warfare, the best choice is to give full play to one's strengths as an infinitely proliferating civilization, and with the blessing of strong manufacturing capabilities, no matter how many destroyers the opponent destroys, more ships will surround it.

In fact, the main problem is that the means of detection in civilized warfare are constantly increasing, and the means of causing damage are getting stronger and stronger; Therefore, at all times, the attack is more dominant.

Ruan Lin directly omitted this technology, and continued to scroll down, there are many strange technologies here, and even a ring called Aquatic Creature Ship Transformation has appeared.

Literally, it is the ship modification technology of aquatic intelligent creatures. It's so big that there's no wonder! Ruan Lin couldn't even imagine what the ships looked like for aquatic creatures.

Quantum computers also appear in it, selling for 3,000 Qiming points.

Ruan Lin cursed secretly again: Qiming Civilization is really not an ordinary black heart! The conscience has not been blackened, and it has not been possible to do such a thing for tens of thousands of years.

The rest of the technology didn't interest him much, and some of it was even more strange than he could accept.

It can also be seen from this that the diversity of the intelligent biological environment in the universe, and some civilizations are indeed unable to develop even basic laser weapons because of the limited conditions of the home planet.

After continuing to scroll through for an hour, Ruan Lin did not see the so-called "advanced technology", most of which were full of technology and could not have a practical effect on the entire civilization.

In terms of materials, it is even more scarce, and Ruan Lin doesn't even bother to click on the introduction of most materials.

"Thank you very much for your hospitality! After discussion, we decided to refund the remaining 0.98 Venus Points, we are not very interested in other products, we are very sorry! ”

Kan Xi said unhurriedly: "Your civilization really doesn't need to think about it again? The environment of this galaxy is too dark, and if you have protective technology, it will make the safety of your civilization a strong guarantee! ”

Ruan Lin looked regretful: "I'm very sorry, we still decided to return it." ”

Canhi grinned, "Of course it's fine! The returned materials will be returned! Please arrange a ship and receive it at the platform! ”

The receipt of the materials was quickly completed, and Ruan Lin also checked the integrity of the galaxy map on the way.

The host equipment and screen are surrounded by 8 robots behind them, which can be worth 900 tons of materials!

A comet-class destroyer soon arrived at the nearest platform, and it was time to say a hypocritical goodbye.

Ruan Lin stood in front of the disinfection cabin and nodded mechanically: "Earth civilization once again thanks your civilization for your hospitality!" Our leaders said that the shopping experience was very good! ”

Once again, Cancy made a professional smirk: "Oh! Thank you for your patronage, we may see each other again, I wish you a smooth journey! ”

Ruan Lin walked into the disinfection cabin without looking back. The Qiming civilization is at least a level 4 civilization, but most of the goods they sell are indiscriminate, and they don't know how high the price of the three-layer heat shield they sold this time can be sold in another civilization!

Ruan Lin looked up at the Qiming: "This is too eye-catching!" Bartering things, things can also be creatures, it's too profitable! ”

After the comet-class destroyer arrived around the Titan, Ruan Lin once again entered the Titan, and the next thing was to return to the surface of the Tiancang Five.

"WIT, all the docks and large ships still revolve around a geostationary orbit, and the Pop-class destroyers return to the surface."

After speaking, Ruan Lin hurriedly turned on the computer, and the sphere of influence of civilization was displayed on the screen!

As I guessed, the Silver Heart is not a paradise of life. A life-sustaining star can only exist in a specific location of the galaxy: not too far from the center of the galaxy, not too close, just as if the Earth were in orbit in the solar system.

The circle near the center of the galaxy is equivalent to a ring of the city, and the closer you are to the center of the galaxy, the more stars there are, but also because of the large number of stars, stellar activity often occurs here, such as supernova explosions, and "filter" gamma bursts also occur frequently.

The map shows that at a distance of 16,000 light-years from the Silver Heart, only 5 intelligent civilizations are marked, each with a sphere of influence of more than 300 light-years. Although the specific data is not marked, they are at least level 4 civilizations!

As a suburban solar system, there are an estimated 1,300 star systems in 100 light years around, and adding the star density around the galactic center, the number of star systems mastered by these five civilizations is at least about 4,800!

Ruan Lin couldn't imagine how fast their ships were and how large their population was, but a civilization that could rule so many star systems must be the pride of the sky.

To put it simply: there are many "old and small" in the inner ring, which is more crowded, and there are often "demolition" situations of old stars.

Although the Earth is located on the Orion arm of the Milky Way, it is indeed a "suburb" of the Milky Way, equivalent to the city's three rings.

But because of the suburb location, the stars here are younger, the older ones are few and far between, and there is less stellar activity.

The concise is: there are more new houses in the suburbs, the spacing is farther, and there are fewer "old and dilapidated small".

Within 20,000-33,000 light years from the Silver Heart, the number of civilizations has reached at least 300! The closer you are to a habitable suburb, the greater the number of civilizations.

But in the outermost part of the galaxy, there are few intelligent civilizations. In a nutshell: galaxy resort islands and villa areas.

Among them, there is a "triangular civilization" with the most prominent sphere of influence, which occupies at least 70 light-years of influence, which is the largest power outside of the five silver heart civilizations.

And the closest wisdom civilization to Ruan Lin, translated into Chinese is "Yuanguang civilization".
