The connection between the moon and the earth has not been fully connected at this time, and it needs to be contacted by borrowing the transfer station of the alliance, and the moon has not received any news about the volcanic changes in the sixth region, and Sun Tan naturally does not know that Mark is in danger now.

After the completion of the placement of the earth, the migration project of the moon began immediately, after discussion, the moon temporarily ** and the alliance reached an agreement, the moon will dock in the orbit of another planet of Tianhua four, far away from the earth, but the planet's highly toxic atmosphere contains a lot of fuel, and the strata are buried with precious metal veins, which are of great benefit to the recovery and development of the moon.

After the placement, the distance between the moon and the earth is about the same as the distance between the original earth and Jupiter, and the two sides can also communicate normally through the spacecraft, and now the human society is vigorously developing space technology, and after the society returns to normal, there will definitely be another big breakthrough in spacecraft technology, and there is no need to worry about the distance. And the moon itself does not have an ecosphere, equipped with an environmental transformation system and dozens of new lunar cities that can still be used, and its tolerance to the environment is much greater than that of the earth, so even if it is closer to the stars, it can still make people live a normal life.

During the period of docking near the alliance world, especially after the end of the peace talks, the moon has become an underground trading post-like place, where many black market merchants of the alliance trade, human civilization has not yet been incorporated into the alliance, but it is not the identity of the enemy, it is in a very embarrassing gray area, such a place is the best soil for black trade, and the circulation of goods has brought a wave of vitality to the moon.

There are many merchants and tourists of the alliance who are interested in human handicrafts, and this feeling is as curious as if they had seen a primitive tribe in modern society. The currency of the Moon to the Alliance is a rare metal ingot, not a rare metal like gold and silver, which is worthless now, the gold monetary system has long since collapsed, and the only thing of value now is something that is helpful for scientific research and industrial construction.

Can be used as currency is lanthanum, cerium, praseodymium, neodymium and other rare earth metals, the alliance visitors refine them into standard size squares, easy to weigh and trade, this kind of thing is not a rare object in the alliance, but it is of great significance to human beings, now human beings have not yet collected outer space resources, rare earth resources on the earth are limited, there is such an additional source, naturally it is better.

In addition, there will also be a lot of alliance's technology products flowing into the human world through trading, the most popular are translation machines, energy blocks and scanners, however, the technology blueprint can't be obtained, although these black market merchants walk in the gray area, but they are still under the control of the alliance, no matter what, they will not touch the red line, technology will not fall into the hands of humans, and the finished products obtained by trading humans are not capable of dismantling, and humans cannot repair them after they are damaged or exhausted.

Even so, the merchants on both sides were still very keen on this transaction, and the collectors and travelers of the Alliance exchanged metal ingots for a large number of human artworks, and the human merchants exchanged them for various Coalition technology products, and this trade continued for a long time, and until the completion of the lunar placement, there were still a small number of black market merchants who secretly went to the moon to trade, and the alliance authorities only turned a blind eye.

Sun Tan didn't care about this, he had seen the alliance's scientific and technological products a few times, and lost interest after finding that they could not be broken down and analyzed, such a thing, no matter how high-tech, was just a toy, useless for scientific research. After Mark left the moon, the research team working on the light-speed spacecraft was handed over to him, and Sun Tan still receives many new proposals every day, but after layers of review, very few are considered valuable, and among these few survivors, there are even fewer of them of great significance.

"What we need is a breakthrough across generations."

Sun Tan is deeply aware of this, although the accumulation of quantitative changes will always be sublimated into qualitative changes, but many scientific and technological breakthroughs in human history have cross-era significance, some people will call this a flash of inspiration, if there is no such aura, human beings may take many detours, such as building a steam-powered computer.

Since a year ago, Sun Tan has been feeling unwell, and after examination, there is no problem, he has always attributed it to his own psychological pressure is too much, but strange things happened one after another, first his skin inexplicably appeared bleeding spots, and then his mobile phone was suddenly damaged, and after disassembling it, he found that several components inside were missing......

These questions have not yet been answered, Sun Tan saw a scene that shocked him again, his antique long-wave receiver that had not moved for a long time suddenly reacted, you know, very few people in the universe would use this method of communication, and it only reacted when the Alliance's collector approached......

Is it the people of the Alliance? Now that the relationship between the two sides is no longer suspicious, is there any need to rely on such opaque communication? Mark was confused, and when he turned on the receiver, skillfully exported the data, and compiled, he felt even more strange, the other party's signal source was very weak, not like a message from the alliance...... Do black market merchants want to trade secretly? Or is it an unintentional interference caused by other civilizations?

Sun Tan couldn't get an answer, but the signals kept coming, which made people a little upset, just when Sun Tan was about to give up, suddenly the other party's signal was stronger, and Sun Tan finally derived a correct and meaningful message......

We, exist.

"What does that mean?" Sun Tan muttered in his heart, and looked at the paper with the answer upside down several times, but he couldn't guess the meaning.

Then there was a large signal for no reason, and after about half an hour, Sun Tan was about to fall asleep, and the other party's signal strengthened again.

From, the small universe, to the giants of the big universe.

Sun Tan suddenly felt a shock in his heart, he seemed to understand something, the whole person bounced up from the chair like an electric shock, he tried to control the long-wave transmitter to reply to the other party, but he couldn't find the other party's receiving channel, and he couldn't do it.

We, in you, you are going to speak, write on paper, we can see.
