"Everyone see what we need or what we can sell." Du Xingyu handed over the task to everyone and asked experts in their respective fields to analyze it one by one.

Soon, scientists put forward their opinions.

"Dean, on the information trading channel, there is a 'black hole explosion' observation data of a level 3 civilization, which is priced at 6.88 million star coins. I suggest it is best to buy it!" Pei Jia said, sending the information to Du Xingyu.

"This is a data record of the explosion of the star cluster. The mass of the explosion is equivalent to 300 million suns, and the black hole jets exceed 100 million years! This third-level civilization has a perfect observation angle and records a lot of valuable information, which will be of great help to our research on black hole bombs."

Du Xingyu read some introductions and thought it was true, so he said, "Then buy this one."

He immediately placed an order. After the photon ball deducted the star coin points, the observation data of the black hole explosion was immediately sent back, and Du Xingyu immediately passed the data back to human civilization.

Green Pupa also suggested on the side, saying: "The first time I come to the trading market, there are some things you will definitely be interested in. You can check it out in the recommendation list."

The recommendation list pops up in the photon ball, and the first one above is a star map of the Milky Way!

This is a star map compiled by the Butterfly Civilization. As a level 4 civilization, it controls wormhole technology. In theory, they can reach any corner of the Milky Way.

This Galaxy Star Map is priced at 10 million star coins.

"Buy!" Du Xingyu did not hesitate at all. Ten million star coins were too cheap!

To allow humans to explore these star fields by themselves, I don’t know how much resources it will cost! Moreover, this star map also marks the territory of some known civilizations.

Of course, 90% of the civilization territory has not been marked. What has been marked is a civilization like the butterfly civilization that announces its own location to the outside world.

For example, the trading market in the angel civilization camp, the trading market in the demon civilization camp, etc.

"There is also information about our Ansu Star Cluster!" Yang Shaolin couldn't wait to check. The standard of the star cluster was not complete. It just gave the luminous and hot stars. As for the civilization of the Ansu Star Cluster, it was not marked.

On the map mark, it shows that there is a level 3 civilization here.

"In terms of physical objects, we have some rare materials here, such as advanced carbon-based organisms and silicon-based organisms' body materials." Green pupa added some things to the recommendation list.

For example, Du Xingyu bought some seeds of life in some kind of plant that can collect stellar energy.

There are also larvae similar to the Zerg "Planetary Devourer", silicon-based life chips, special materials, etc.

It was a mess, Du Xingyu spent more than three million star coins, so that their human civilization's commercial ship was only more than one million star coins left.

In just a few minutes, the purchasing power they spent was enough for all the stellar furnaces and factories of human civilization to start construction for ten years!

But these costs are indeed the result of new technologies and breakthroughs in all walks of life, which is completely worth the money.

"Hisser Green Pupa, are there any higher-tech products here?" Du Xingyu decided to save some money. Human civilization has too thin and there are not so many resources to exchange for.

"Of course there is!" Green Pupa said directly, "Technology, important information, etc. that exceed 3.5 levels will not be directly hung in the trading hall."

Du Xingyu could understand this. He observed that most of the sold products in the trading hall were finished products, and there were few hard-core products such as scientific and technological theory.

For example, the gravity cannons and other weapons sold are all secret locks. Even if they are bought for level 3.0 civilization, they cannot crack them. Once they are forced to crack them, the weapon will destroy itself.

This means that it is only sold to other civilizations to consumables without telling them the true core of technology. It is equivalent to disguised economic plunder. Although other civilizations know this, they cannot resist the temptation of these high-end technology products.

Because these products are much more powerful than their own technological creations, if they have them and the enemy does not have them, they can defeat the enemy.

If the enemy has it, they don’t have it, the enemy will plunder them. In this way, even if the resources of civilization are exhausted, they will have to buy such weapons.

In such internal friction, the scientific and technological development of this civilization itself may be seriously restricted.

"We have better recommendations for your human civilization." Green Pupa said, "The trading location is in the Star Pirate Civilization Trading Market on the other side of the upside-down city."

"Then let's go now." On the way to the Star Pirate Civilization Trading Market, Green Pupa took them to see other territories here.

For example, the Sensory Entertainment Center, where the food, smell, light, and various items that stimulate the brain are loved by carbon-based civilization are sold and served.

Even silicon-based civilizations can be used to enjoy using Super Dream, an electronic technology that stimulates silicon-based chips. You can also replace the parts of your body, transform and upgrade them, etc.

Du Xingyu also saw civilization games. Advanced civilizations built low-level civilizations into real game worlds, similar to Blue Star civilizations, for residents of advanced civilizations to entertain and experience.

The Interstellar Museum has various civilized objects, racial specimens, and living specimens.

The slave market is also a very popular place. Some civilizations like to come here to find gold. The most valuable ones are the captured high-level civilization scientists, who are often priceless. Secondly, they are some resource species, opposite sex, etc.

The Military Weapons Exhibition Hall is also a popular place here. Many civilizations will hang military weapons that they can trade here. Du Xingyu and others even went in and took a walk around, and he felt a little disappointed.

Most of the weapons exhibited and sold in the exhibition hall are antimatter weapons, primary gravity weapons, etc. Really advanced weapons, these civilizations will not sell them.

In some high-end weapons exhibition cabinets, there are only virtual images and no physical items sold.

After passing the gravitational adaptation field in the middle of the upside down city, Green Pupa brought everyone from human civilization to the other side of the star pirate civilization trading market.

"The transactions here are even more crazy than just now. The buyers and sellers here are confidential, so you can check them with confidence." Green Pupa introduced.

On the photon sphere, Du Xingyu received some push information.

He looked a little and found that the green pupa was indeed not lying.

"For sale of the star system, the main star is a young star with a lifespan of 300 million years, with a mass XX. There are five rock planets in the star system and three gas planets. The mass and volume are XX respectively. There is no third-level civilization within one hundred light years. The price is 500 million star coins. If you are interested, you can give one of the original civilization if you purchase it! (Show the interstellar coordinates after paying the deposit)"

"The second-level silicon-based civilization is sold. The civilization has great potential, and it is very convenient to cultivate war weapons or resource miners. The current population is 18 billion, with 300,000 star-level silicon-based creatures and 10 billion planetary silicon-based life... The price is 789 million star coins, free shipping in the Orion arm, and other cantilevers require additional postage."

"Star Domain-class fleet is for sale!!! One thousand medium-sized star Domain-class battleships, the maximum distance of super-space transition can reach one hundred light years! Twenty thousand primary star Domain-class battleships, the distance of super-space transition is more than thirty light years. The mothership is a high-level star Domain-class battleship, equipped with antimatter weapons and gravity weapons... Those interested in private chat! The Orion arm is free shipping, and you can return and exchange goods for free within ten years!"

...

The recommended orders to Du Xingyu are all big orders, and everyone who sees the senior human civilization in the transaction information is moved.

Whether it is a star-domain-class fleet, an affiliated civilization of silicon-based civilizations or a resource-rich star system, no matter which one is a huge wealth.

"I really want to add them to the shopping cart!" Mo Caiwei said in a heart-warming manner.

"If we want to buy these things, we have to sell more resources. The resources we brought this time have been sold out, so we can only sell technological information and intelligence information next." Lu Xing analyzed.

"Don't worry," Chen Hong said, "The authenticity of this information is unknown, and we cannot guarantee that what we buy is a product of excellent quality."

"For example, the star system, he said that there is no level 3 civilization within one hundred light years. If there is a level 3 civilization within two hundred light years, or even multiple level 3 civilizations around it, can this star system still be bought? If you buy it, you will soon be occupied by other civilizations."

"There are also secondary silicon-based civilizations, which are very difficult to control. They are not subject to environmental conditions and can grow and grow by throwing a planet at will. If this silicon-based civilization rebels every day, we will not only not be able to gain resources, but also invest in troops to suppress them. Wouldn't that be a loss?"

"As for the star-domain-class fleet, I have doubts about the data inside. The highest leap of 100 light-years means using up all the energy? The performance is not as good as our warships. Maybe it is a waste product eliminated by other civilizations, because it is very troublesome to deal with it, so I will just be pulled over and sold."

It also costs a lot of money to deal with eliminated warships.

"Chen Hong is right. The first time we are here, we must be calm and not be cheated." Du Xingyu agreed.

"Dear guests of human civilization? If you are interested in the transaction content, you can talk to their sellers." Green Pupa said, "You may not believe some information. I must admit that some civilizations may exaggerate publicity, but sometimes they may find some treasures."

"For example, some star pirate civilizations are threatened by other civilizations and have to give up some precious resources and technology in exchange for the opportunity to survive. At that time, those who take decisive actions will buy great value for money!"

He said, suddenly jumping to the topic, "I just received two messages, both of which are closely related to your human civilization."

"What news?" Du Xingyu asked.

"The first is an invitation letter, and someone invites you to visit." Green Pupa said, "It is the third-level civilization of the Angsu Star Group."

"Invite us?" Du Xingyu was shocked, "Do they know where we are?"
Chapter completed!
