"What is this? An unmanned spacecraft? ”

On this day, several operators in charge of monitoring found a very small circular spacecraft not far from the Noah, like a flying saucer.

“…… New Human Civilization...... Gift...... New Human Civilization...... Gift ......"

The radio on the circular spaceship is constantly broadcasting its location, making it easy for humans to spot it.

It should be something related to the green light civilization, and the relevant staff quickly submitted the relevant report.

……

In the conference room, everyone felt inexplicable.

"This is supposed to be a drone for transporting goods. Didn't the Green Light people say that in order to make up for the loss of the new human civilization here, they were willing to give 0.3 units of 'inverse entropy field aggregation particles' to humans? They shipped the gift through this drone! ”

One of the councillors suddenly slapped his head and said loudly.

People immediately reacted, the other party did say this, everyone has been so busy these days that they almost forgot. The sun is about to explode, who cares about any gifts?

In other words, this is the compensation that the Green Light people give to the new human civilization? It's ...... Is it "anti-entropy field aggregation particles"?

Yu Yifeng frowned, he didn't know what the hell the so-called "inverse entropy field aggregation particles" were, but it was very precious when he thought about it. Because the Greenlight people seem to be very confident that they can use this thing to buy humans into not attacking their ships......

Yu Yifeng was pondering, and suddenly his eyes lit up, it didn't matter what it was. For human beings, the most precious thing is still that - a small round unmanned spacecraft!

With a diameter of only about two meters, it can be said to be very miniature. But it's such a small thing, in two weeks, spanning 85 astronomical units!

What does this mean?

Its flight speed is very fast, with an average speed of 1/30 of the speed of light and a speed of 10,000km/s, far exceeding the limit of human aircraft!

"Send a robot and bring it back." Yu Yifeng immediately clapped his head.

Humans are qualified junk buyers...... No, this is something that was deceived by ability, and it can't be said to be picking up rags, don't do it in vain.

Many scientists have also thought of the key and are excitedly gearing up. What does a full-fledged drone mean? It must have a complete engine and power facilities, and even a complete set of technology system!

This is not a tattered UFO creation that most of them cannot be used.

The people of Green Light could never have imagined that the new human civilization, which seemed to be "powerful", would be excited for a long time because of a drone......

A "powerful" new human civilization keen to pick up rags?

"Ahem!" Yu Yifeng coughed dryly.

In terms of scientific and technological research, please talk about it later, no matter what, we have to get through this life-and-death crisis first, and then these crazy scientists have the life to study.

A short time later, automated robots transported the small unmanned spacecraft back and placed it in a small room on Mars.

Because they still want to conduct thorough research on this drone, humans do not want to destroy it, so they can only carefully detect its danger.

Ever since the lesson learned, humans have been very cautious with any unidentified object. Although the probability of the Green Light people having bad intentions is very low, it is always good to be careful.

It looks like a flying saucer, measuring about 2 meters in diameter. The transport robot transported it to a closed room, where it was disinfected and tested. After half an hour, several mice were also herded into a closed room and will spend some time with the drone.

This airtight chamber is very thick and built on the surface of Mars, so even if there is an "antimatter bomb" in the spacecraft, it will not cause any damage to Noah.

People are very cautious, and although they are a little excited in their hearts, they don't want to overturn for some inexplicable reason......

"Okay, you can manipulate the robot to open it and take a look." Yu Yifeng said: "What precious gifts have the Green Light people brought us? ”

He was also very curious in his heart, what could buy a civilization?

Human beings are very lacking in the common sense of the universe, and they do not know what the unit of transaction between civilizations is. According to the basic logic, the "anti-entropy field aggregation particles" mentioned by the green light people should be very precious......

Whatever this thing is and what it is for, it should be of high value among interstellar civilizations. This information is very important, and from now on, if human beings really deal with other civilizations, they will have a little foundation, and they will not be like a blank sheet of paper.

In the middle layer of the small drone, there is a glass cover-like thing, and there are several very obvious raised buttons under the cover, and there are three Arabic numerals "1, 2, 3" on it!

People were a little surprised, but soon calmed down. The Green Light people have even learned some Chinese, and it is not surprising that they have learned Arabic numerals. And in the dictionary sequences that people have sent in the past, there are such Arabic numerals.

Mathematics is certainly common to all intelligent civilizations. Now that the Green Light people use numbers as notes, they can only say that the logic of the two civilizations is really very similar.

Under the control of the mechanical arm, the glass cover was lifted, revealing the three buttons underneath. In fact, there is still a trace of hesitation in people's hearts, because ...... There may also be a trap in the drone, maybe it is a virus or a nuclear bomb?

"It stands to reason that they don't have to. If they don't see through our disguise plan, they will only offend us by putting a trap. ”

"Yes, it does......"

Everyone whispered that theoretically it wasn't very dangerous to open this thing, but who knows? There will still be risks.

"Open it!" Yu Yifeng stared at the screen tightly and finally gave the order. In fact, this thing has to be opened sooner or later, and there is nothing to hesitate about.

There was a soft "drop" sound, and after pressing three buttons, the drone cocked a round lid, inside which a delicate metal box was placed.

The robot opened the box again and found a round, crystal-like substance lying quietly inside. It's about the size of an egg, and it sparkles in the light, and it's beautiful.

"That's what it is...... Aggregate particles with an inverse entropy field? ”

There was a lot of talk, well, it does look like a piece of crystal, or special glass. Don't...... This thing is a unit of trade between interstellar civilizations?

Yu Yifeng also felt that the second monk was confused, if the crystal was the basic trading unit, it would be too weird, right? With the production capacity of the Noah, it is not a problem to manufacture at least tens of thousands of pieces a day.

Artificial crystals are not difficult, that is, adding 24% lead oxide to ordinary glass (silicon dioxide) will give artificial crystals with similar brightness and transparency to natural crystals. Isn't there silicon on other planets? Or is there no lead? Impossible......

"No, there's something in there!" Just when everyone was puzzled, a sharp-eyed scientist suddenly shouted.

The cry was so loud that many people immediately stopped the discussion and turned their eyes to the screen.

"Enlarge the image!"

As the screen slowly zoomed in, Yu Yifeng finally saw what was wrapped inside.

It was very small, not even as big as an ant's leg, and it is not known how the scientist saw it.

At this moment, Yu Yifeng felt a cold sweat all over his body, his heart was beating "dong", and a voice shouted frantically in his head:

"What the...... Isn't it perfect?!! ”
