Day after day, all kinds of scientific and cultural exchanges and trade activities are also going on in an orderly manner. Zhang Yuan even joined a free concert held by aliens with a group of companions. Yes, you must participate in free things.

But the sound frequency of the concert was all ultrasonic... So that everyone wasted a few hours like a goose

In addition, the group also visited the so-called "Green Star Civilization Museum" carried out by a civilization. Because the green star civilization has disappeared in the galaxy, the leftover things have become quite valuable cultural products. Green Star civilization is famous for its powerful means of biological smelting. Most of the museums are strange creatures. Zhang Yuan saw something like a cannibal flower with his own eyes. After swallowing the ore, he spit out the finished metal

Well, humans don't need this biotechnology, but they have seen another technology tree in the universe.

Leisure time always passes quickly. On the 98th day when we came to the trading market, Huantai civilization suddenly sent a notice.

"Dear human civilization, hello. Your trade application with Hicks civilization has ranked first. Please make relevant preparations before cosmic time ad782345-7821-0098. Thank you! "

"The specific trade contents are as follows..."

This time, converted into the standard time for adults, is about 2:00 p.m. on the third day. Everyone looks very excited after learning the news, and then starts to prepare relevant materials and take a rest.

This short preparation time passed quickly. Everyone put on their own power armor, that is, the latest tx-007 model, and stepped into an alien spaceship with Thai civilization.

As it is of great importance, there are only seven people in the whole diplomatic team, and Zhang Yuan happens to be one of them... Frankly, he is going to be responsible for "friendship".

After all, Zhang Yuan is the only human being who has come into contact with the Gaia faction.

What if they know each other? Maybe... Can you beg for something again?

Well, can't you say it's begging? But... Pleading?

They don't carry much information. Some storage devices store the detailed history of mankind. From the Neolithic Age to modern times, there are about 150 million words in all countries, large and small, including all kinds of encyclopedias. Of course, the more backward the history is, the simpler it is, especially the content about the virtual world has been deleted.

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

Including the oil painting starry night given to Zhang Yuan by the painter Elvin when the earth times set out. This painting was rated as the outstanding art of the new civilization and his private property of Zhang Yuan... But it's no problem to contribute to the whole civilization.

Finally, it is to collect the historical data of low-level civilization and culture and art along the road.

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

The spaceship of Huantai civilization is about two kilometers in diameter and looks like a large flying saucer. Because the fourth level civilization still does not realize artificial gravity, the periphery of the flying saucer will rotate slowly to simulate gravity. So after everyone entered the spacecraft, they were in a low gravity state.

"Hoo..." Zhang Yuan took a deep breath. The feeling of landing on an alien spacecraft was very subtle. He looked at the metal used in the whole room and didn't see much clue.

"If only we could have our own trading market."

We have long seen the benefits of a trading platform. Even humans have gained a lot in these days. How much can Huantai civilization, the host of this exchange, gain in these millions of years?

However, for some reason, the Huantai civilization is still only a fourth level civilization.

It seems that there is a natural moat with high difficulty, which is horizontal among all interstellar civilizations. Philosophy tree is not so easy to climb. Perhaps, Huantai civilization still doesn't know what it should do in the future and why it can strive for life.

"Yes." Foreign Minister Chen Mu whispered, "the key is to have a good reputation and strong enough strength. How can there be several planetary fortresses? Otherwise, everything will be a mirage. "

Zhang Yuan suddenly thought, "we humans have actually split into several different civilizations. If we go back, is it possible to establish a human trading alliance?"

Chen Mu shook his head: "it's possible, but it doesn't work. They are all human, culturally similar, with the same body structure, the same technology tree, and the same thinking mode. I don't think such an alliance is of great significance. It's just that the population has increased and can't compare with a more civilized trading market. "

"That's true."

During this conversation, the UFO broke away from the gravity of the planet, started curvature sailing and started super-high-speed sailing. Everything outside the window seemed to be trapped by a soap bubble and became blurred. Without any instruments, Zhang Yuan and others can only look with their eyes and can record more data with power armour

After about three hours, the UFO approached a seemingly transparent circular fortress in the outer area.

Then, everyone sat on a huge vehicle. The whole car looked a bit like a human bullet, and the internal space was enough to accommodate hundreds of people.

The vehicle starts slowly and smoothly.

"You don't have to worry too much... The launch cost of every data of superluminal communication is very expensive, and Hicks civilization will bear all the costs..."

"But I also hope you don't send false content. If a large number of false contents are identified, your civilization will be blacklisted. "

"Of course not. We are not star bandits. "

Inside the car, the tour guide of the Huantai civilization, cocoa filiform wart, followed by several large and long reptiles, possibly soldiers or servants. Because all the insects are wearing mechanical devices, we can't see what kind of body structure they are.

However, in terms of length, the length of each large reptile is about 3 meters. There is a brain tumor like protrusion in the middle of the body, which has derived some tentacle like things.

It doesn't look very cute anyway.

Zhao Qingfeng couldn't help asking, "so, won't Hicks civilization contact us directly?"

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

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

Zhang Yuan looked at the scenery outside the window. This circular fortress is quite empty, just like a magnificent religious palace. Looking from the inside to the outside, it is actually transparent and can see the bright Milky Way sky.

"Excuse me for asking, is this a spaceship built for you by the amoeba civilization? How can we join the amoeba faction? "
