PS: Two chapters in one. Fortunately, I was not dishonored, and I finally finished writing before twelve o'clock, and I was going to be exhausted......

The Blue Star Planet Fortress drove through the metal galaxy at a high speed, and there were no speed limits in some specific areas, so it only took half a day for the Blue Star Planet Fortress to land on the Rheinsain Star.

This is the trading planet of the Quians, and it is about the size of one and a half suns. The entire trading planet is covered in dull metal, but there is a light coming from thousands of merchants, making the whole planet look like a giant lantern, and the light from one shop after another converges into a beautiful picture.

And following the rays on the star Rheinsain, it can be clearly seen that the planet is divided into thirteen parts, twelve of which are all the same size, and only one part at the pole of the planet emits a brighter light than the others.

It was the thirteenth district of the Rhine-thane star, and it was also where the auction was held, and even in the starry sky, you could see the huge building that occupied two-thirds of the territory of the thirteenth district, and that grandeur could not be summed up in terms of mere size.

The Blue Star Planet Fortress slowed down and came to a halt on a huge metal ring five million kilometers from Rheinsain, and was not allowed to fly any further. According to the star map, no non-Star Pirate Alliance aircraft are allowed to fly within five million kilometers of the outer star sky of Rheinsain, and only extreme evolutionary civilizations like the intelligent beasts can fly over by themselves, but they must also have patrol robots to follow.

Wearing the exoskeleton power armor, Meng Ke took Lu Yue and a group of Terminators down the Blue Star Planet Fortress, came to a spaceship berthing area in the metal ring, and took a free passenger spaceship to land towards the Rheinsain Star.

On the way, Meng Ke saw a familiar thing - space-based kinetic energy weapons.

That's right, just like the dozen space-based kinetic energy weapons that Meng Ke once made on the earth, there are also space-based kinetic energy weapons outside the Rheinsain Star. Although the appearance of these space-based kinetic energy weapons was different from what Meng Ke had once made, Meng Ke still recognized their true identities at a glance.

This made Meng Ke very puzzled, it stands to reason that low-level weapons like space-based kinetic energy weapons should have been eliminated long ago. Even a fully developed second-level civilization could no longer use such a thing.

Because to put it bluntly, space-based kinetic energy weapons are weapons that are only used when civilized races are fighting among themselves, and they are completely useless in galactic warfare, unless an alien race invades the surface of the planet...... But at that time, space-based kinetic weapons were estimated to have been shot down by the opposing warship, so they were useless.

So, why does a fifth-level civilization of the Ku'an tribe still use this kind of thing?

I'm afraid that the answer to this question will only be found when it falls to the ground......

Rumble!

The massive transport ship landed on the metal floor of the tarmac with a muffled sound.

Then, the hatch of the transport spaceship slowly opened, and one after another the lifeforms of the major civilizations and races wearing various exoskeleton power armors walked down one after another, and Meng Ke and Lu Yue fell last. Several Terminators escorted him down in four directions, front, back, left, and right.

This posture naturally attracted the attention of some of the lifeforms parked here outside the spaceship.

There's no way, Meng Ke's image doesn't want to attract attention, at a glance, you can know which civilized race it is, and immediately there are many lifeforms wearing exoskeleton power armor or not wearing exoskeleton power armor.

Similar to the pimps in the shops of the Coronde Civilization Market, these beings are also here to sell themselves or their shops. However, unlike the pimps in the shops of the Coronde Civilization Market, these people are much more popular, and often start a war of scolding at the slightest disagreement, in this area where they can't fight. Scolding became the only thing that would decide the winner.

Meng Ke ignored the sales pitch of these pimps, and the terminator squeezed these people away, and he was walked forward by Lu Yue's arm.

For Meng Ke's ignorance, these pimps could only scold and say a few words. But they did not dare to forcibly intercept it. If they do that, I'm afraid they will be blown to smithereens by space-based weapons in an instant - the rules of the Rheinsain are very strict, and it is strictly forbidden to buy and sell.

So, on the planet Rheinsain there is an intelligent system similar to that of an executioner. These intelligent systems operate space-based weapons and are used to execute buyers or sellers who don't follow the rules – even if they kill people on the spot. Who would dare to oppose the decision of a fifth-level civilization?

Even if it is a race that is also a fifth-level civilization, it must be weighed when opposed, after all, the Ku'an tribe is not an ordinary fifth-level civilization. It is also a fifth-level peak civilization, and is one of the three elder races of the Star Thief Alliance's Elder Sect. It can be said that the matter of the Ku'an clan is a major matter of the entire Star Thief Alliance, and no one dares to make too much of it.

Meng Ke also didn't know about this.

At this moment, he was strolling along a shopping street.

However, it is a shop street, Meng Ke sees that this place is no different from a vegetable market, the whole street is noisy, as many as dozens of races of life forms are crowded in it, the sound of buying and selling is endless, and even many goods are placed outside, making it look like a wholesale market in addition to a vegetable market.

Meng Ke only walked around for a while, and then directly blocked all the sounds. No way, it's just too noisy here.

"Xianggong, where are we going?"

As soon as the sound of the outside world was blocked, Lu Yue's voice came from Meng Ke's ears.

Meng Ke thought for a moment and said, "Let's go to the currency center to exchange some currency first." ”

"Okay." Lu Yue nodded, and continued to hold Meng Ke's arm, but the big eyes in the exoskeleton helmet were already full of novelty.

It's hard to imagine that a person who is already hundreds of years old will have the same curiosity as a child, which is a rare one.

Returning to the outside of the shopping street, Meng Ke first asked the terminator to ask the service robot for the location of the currency center, and was told that the currency procedures could be handled through the service robot.

After getting this news, Meng Ke immediately exchanged ten second-level civilization technology trees and three third-level civilization technology trees for millions of currency...... Of course, there's more to the currency than just exchanging it for a tech tree.

However, Meng Ke is now in addition to the technology tree and the technology tree, but there is one in the planet fortress, but it is his car

After putting away the score card, Meng Ke then spent ten points to buy a map from the service robot, and then flew to the passenger transportation center with Lu Yue and the Terminators. Sector 7 was reached via a machine called the "Space Teleporter".

The seventh region is on the other side of the star, overlapping with the first region where Meng Ke landed. The seventh district has the largest trading mall in the entire Rheinsain Star, whether you want to think of it or not, there are all of them here, and they are all dirty, and the highest level of goods is the items of the mid-level civilization of the fourth level, and the items above the middle of the fourth level have long been sent to the auction.

After Meng Ke and the others came out of the space teleportation device, except for the Terminator, Meng Ke and Lu Yue all felt a burst of dizziness, which gradually disappeared under the alleviation of the medical function of the exoskeleton power armor, and it felt even more uncomfortable than sleeping in the hibernation pod for a year.

Just look at the time. Meng Ke was even more surprised, it only took a second to teleport from one side of the star to this side, such a speed was simply terrifying.

I just don't know how this thing works, but unfortunately the technology gap is too big, and even if all the scientists in the Federal Academy of Sciences are brought together, they may not be able to get one percent of its technology out.

Shaking their heads, the group flew towards the trading mall marked on the map.

The entire trading mall is a huge metal building, with various shops set up inside, with a total of 13 floors from low to high. I don't know if it corresponds to the thirteen districts or what.

However, compared with the trading area of the first district, the trading mall in the seventh district is obviously much more high-end. At least on the surface, there are no more items on the street outside, everything is done inside the store. Special soundproofing devices keep out all kinds of bargaining and bickering, and although the streets have been turned into corridors, they are not crowded.

In front of the mall, there is a huge floating screen with a map of the first floor of the mall. Customers who come to trade can look for their favorite store on it, and just click on the name of the store to see the introduction.

Meng Ke and his entourage wandered around the trading area on the first floor of the trading mall for a while, and then went directly to the thirteenth floor.

The thirteenth floor of the trading mall is significantly smaller by two-thirds than the first. However, it looks more spacious than the first floor, and there are only about 20 shops scattered in three directions on the thirteenth floor, and the only constant is probably popularity.

Don't look at the fact that there are only more than 20 shops here, in fact, these shops are the top shops established by the elders of the Star Thieves Alliance, and the things sold in them are also more advanced than all the shops on the first twelve floors, basically except for those that were sent to auction, 97% of the good things in the entire trading mall are here.

When Meng Ke and his entourage entered one of the stores, they could feel the gap between the shops here and the shops below.

No one received it, not even a robot, the names of all the products were displayed on the shelves on both sides of the store, and the customers were asked to choose by themselves, and a waiter sitting behind the counter had no intention of getting up at all - even if there were only Meng Ke and his party in this store.

"Ultra-long-distance information transmission technology, purchase price: twenty resource planets, or two complete technology trees containing all the scientific and technological materials of early civilizations from level 1 to level 4."

"Space Fold Technique, purchase price: five hedrons of any civilization, or a complete tech tree containing all the technological information of mid-level 1 to 4 civilizations."

"270 times faster-than-light engine, purchase price: fifty planets of resources, or one ton of dark gold."

"A complete three-level pinnacle creature civilization, the purchase price is ......"

"A complete three-level pinnacle extreme evolution civilization, the purchase price is ......"

“……”

Looking at it row by row, the more Meng Ke looked at it, the more frightened he became.

Don't look at the few goods on the shelves of this store, none of them are defective, all of them are high-end goods, and their exchange prices are also extremely high, and many of them are unheard of by Meng Ke.

For example, the resource planet and dark gold should be a special substance that has not been discovered by the earth civilization so far, and the analysis diagram of these two substances given in the purchase price also shows this - the structure of those two substances is more complex than the most complex substances known to the earth civilization, and I really don't know how dense this thing is in the real world.

The most important point is that the currency that seems to be exchanged by Meng Ke is of little use here......

Although the currency could not be used, Meng Ke was a little depressed, but in the end, he exchanged a complete technology tree at the pinnacle of the third-level civilization for the design blueprint of a primary gravity traction weapon.

Although the Federal Academy of Sciences is now working on a gravity collapse weapon, that weapon will not be perfected in a moment. Gravity pull weapons are the same type of weapons as gravity collapse weapons, but they are less powerful than gravity collapse weapons and are easier to study.

The blueprint of this gravity traction weapon exchanged by Meng Ke is a finished product, and it is basically the same as the current research direction of the earth civilization on gravity collapse weapons, and it only takes a few glances to integrate into the technology tree of the earth civilization, and even improve the real gravity collapse weapon because of this, which is a matter of killing two birds with one stone.

Perhaps with those technology trees given by Zhi Brain, Meng Ke is a bit redundant to redeem this drawing, but to some extent, it is more suitable for earth civilization than those recorded in the technology trees given by Zhi Brain.

Although there are many technology trees given by the brain, there are very few technologies that can truly integrate into the earth's civilization without conflict, and the design similar to gravity collapse weapons is even more bizarre, and federal scientists can only choose some technologies to make up for the best, and dare not copy them all, which will slow down the speed, and even consume a lot of time in researching those technology trees.

The blueprints exchanged by Meng Ke are different, and it can be said that they only need a few modifications to be perfectly integrated into the technology tree of the earth's civilization, and there is no need to worry about any conflicts.

For the current earth civilization, time is life, and if you can save it, you can save it. In the war of genocide of cosmic civilizations, maybe one day the earth civilization will encounter a huge crisis, how can it be without strong force?

After paying the bill, Meng Ke and his party walked around the other shops a few times, and each bought a few drawings of weapons, engines, or protective shields that were useful for the earth's civilization, and then the group turned around and left.

Through the spatial teleportation device, Meng Ke and his party directly teleported to the thirteenth district.

When I got here, it was a completely different scene...... (To be continued......)
