Time passed day after day, and various scientific and cultural exchanges and trade activities were also carried out in an orderly manner. Zhang Yuan even attended a free concert held by aliens with great interest with a group of companions, and yes, free things must be attended.

It's just that the sound frequencies of this concert are all ultrasound...... So much so that everyone wasted hours in vain like goosees......

In addition, the group also visited the so-called "Green Star Civilization Museum" carried out by a certain civilization, because the Green Star civilization has disappeared into the galaxy, and the things left behind have become quite valuable cultural products. The Green Star civilization is known for its powerful biosmelting methods, and most of the museums are full of strange creatures, Zhang Yuan saw with his own eyes something like a man-eating flower, swallowed the ore, and then spit out the finished metal product......

Well, humanity doesn't need this kind of biotechnology, but it's kind of seeing another tech tree in the universe.

Leisurely time always flies quickly, and on the 98th day of coming to the trading market, Huantai Civilization suddenly sent a notice.

"Dear human civilization, hello. Your trade application with the Hicks civilization is in the first place, please prepare before AD782345-7821-0098, cosmic time, thank you! ”

"The specific trade content is as follows......"

This time, converted to human standard time, is about two o'clock in the afternoon of the third day, and everyone is extremely excited when they learn the news, and then they start to prepare relevant materials and do a good job of resting.

This short period of preparation time passed quickly, and everyone put on their power armor, the latest TX-007 model, and stepped into an alien spaceship of the Rim Thai civilization.

Due to the importance of the matter, there are only 7 people in the entire diplomatic team, and Zhang Yuan happens to be one of the 7 people...... To put it bluntly, he is going to be responsible for the work of "climbing friendship".

After all, Zhang Yuan was the only living form among the human beings who had come into contact with the Gaia faction.

What if the other party knows each other? Maybe...... And be able to beg for something?

Well, can't it be said to be begging? But...... Implore?

They didn't carry much information, some storage devices, which stored the detailed history of mankind, from the Neolithic to the modern era, all large and small countries, the total number of words, about 150 million, including all kinds of encyclopedias. Of course, the further back you go, the more brief the history becomes, especially the part about the virtual world, which has been removed.

There are also paintings, music, sculptures and other works of art, which are packed in a large box.

Including the oil painting "Starry Night" given to Zhang Yuan by the painter Erwin when the Earth Age set off. This painting was rated as the outstanding art of the new civilization, and it was his personal private property...... But for the sake of the civilization as a whole, there is nothing wrong with contributing.

Finally, it is to collect historical materials, culture and art of low-level civilizations along the way.

The total information adds up, and one cubic meter of box is enough.

The spaceship of the Huantai civilization is about two kilometers in diameter and is shaped like a large flying saucer, and since the fourth-level civilization still does not achieve artificial gravity, the periphery of the flying saucer will rotate slowly, simulating gravity. So when everyone enters the spaceship, they are in a state of low gravity.

"Whew......" Zhang Yuan took a deep breath, this feeling of landing on an alien spaceship was very subtle, he looked at the metal used in the entire room, and did not see any big clues.

"It would be nice if we could also have a trading market of our own."

The benefits of a trading platform have long been seen by everyone, and even human beings have gained a lot in these days, so how much can the host of this exchange, Huantai civilization, gain in these millions of years?

However, I don't know for what reason, the Huantai civilization is still only a fourth-level civilization.

It seems that there is a moat of outrageous difficulty, which lies in the middle of all interstellar civilizations. The philosophical tree is not so easy to climb, perhaps, the Huantai civilization still does not know what it should do in the future, and does not know what it can do for life.

"yes." Foreign Minister Chen Mu said in a low voice: "The key is to have a good reputation and strong enough strength, no matter how many planetary fortresses there are, right?" Otherwise, everything is in the mirror. ”

Zhang Yuan suddenly thought about it: "Our human race has actually split into several different civilizations, if we go back, is it possible to establish a human trading alliance?" ”

Chen Mu shook his head: "There is such a possibility, but it has little effect." All human, culturally similar, with the same body structure, similar tech trees, and similar mindsets. I don't think this kind of alliance is of great significance, but the population has increased, and it is not as good as the trading market of many civilizations. ”

"That's right."

In the middle of the conversation, the flying saucer broke free from the gravitational pull of the planet, started the curvature voyage, and began to sail at super high speed, and everything outside the window seemed to be covered by a soap bubble and became blurred. Since they didn't carry any instruments, Zhang Yuan and the others could only look with their eyes, and it would be good to be able to record more data with the power armor......

After about three hours, the saucer approached a circular fortress that seemed to be transparent in the outer area.

Immediately afterward, everyone sat in a huge vehicle that looked a bit like a human bullet, and the interior space was large enough to accommodate hundreds of people.

The vehicle starts slowly and very smoothly.

"You don't have to worry too much...... Every piece of data from faster-than-light communication costs very expensive to transmit, and the Hicks civilization will bear all the costs......"

"But hopefully, you don't send fake content. If a large amount of false content is detected, your civilization will be blacklisted. ”

"Of course not. We're not interstellar bandits. ”

Inside the car, the person who received the group was the tour guide of the Huantai civilization, cocoa filamentous warts, followed by several large and long reptiles, possibly soldiers or servants, etc., because all the insects were wearing mechanical devices, but it was not clear what kind of body structure.

However, in terms of length, the length of each large reptile is about 3 meters, and there is a brain tumor-like protrusion in the middle of the body, which derives some tentacle-like things.

Anyway, it doesn't look very cute.

Zhao Qingfeng couldn't help asking, "In this way, won't the Hicks civilization have direct contact with us?" ”

"Normally, the Hicks civilization is not in the galaxy. You can transfer all your data to the past...... If your history and culture are ordinary, the other party will pay a certain amount of amoeba points directly and will not talk to you. ”

"If your history and culture are quite interesting, the other person may choose to talk to you...... Of course, this probability is very small, maybe only once in tens of thousands of years. ”

Zhang Yuan looked at the scenery outside the window, this circular fortress was quite empty, like a magnificent religious temple, looking from the inside to the outside, it was actually transparent, and you could see the bright Milky Way starry sky.

"With all due respect, this is a spaceship built for you by the Amoeba civilization? How can I join the amoeba faction? ”
