Suspended silently tens of billions of kilometers away from the fleet, Planet Raqqa is like a lost world, full of endless mystery and darkness.

The planet Raqqa has thick clouds, which are even thicker than those on Venus in the solar system. As a result, the probes launched by General Emak were unable to obtain information on the planet's surface. In this case, sending robots to land on a planet is the most appropriate thing to do. If, after robot exploration, it is determined that there is no danger on the planet Raqqa, it will not be too late to send humans to land at that time.

A formation of robots is launched from one of the ships and embarks on a journey into the darkness. It will take more than ten days to sail to the planet Raqqa, and then reveal the truth hidden by the thick clouds to those who wait here.

Xiao Yun and General Emek saw the message transmitted by these robots in the combat command hall. There is virtually no visible light on the surface of Rakqa, so these robots are shot using infrared, which results in people always seeing images with a strange hue that looks like some old video footage that has lost its true color.

This was the first time that the people in the fleet had seen the surface of Planet Raqqa, but these things were not unusual to Xiao Yun. Because decades ago, Xiao Yun had lived in this environment for a long time.

Whether it was the undulating mountains or the vertical and horizontal ravines, and the strong winds that could blow away the boulders, these things were all familiar to Xiao Yun. Just a little bit...... Although mountains are still mountains. Although ravines are still ravines. But their appearance was a little different from what Xiao Yun had seen before.

The mountains, of course, rise high above the earth. But at the moment, the mountains above the planet Raqqa don't look like that. If I had to describe it, it would be...... They seem to be piled up, not pierced from beneath the earth. Xiao Yun struggled to think of adjectives in his mind, and after a long time, he suddenly remembered that these mountains were almost the same as the sand dunes in those deserts above the earth.

The same is true of the ravines, which are no longer sharp, but very gentle. It's like a small ditch blown out by the wind in the desert. And the earth...... Nor are they one or the same. When the robot focused its camera at them up close, Xiao Yun could even detect the granular structures.

General Emak turned to Xiao Yun and asked, "Although I don't know much about the planet Raqqa, I probably remember it...... Planet Raqqa seems to be a very moist planet with very rich landscapes, and it doesn't seem to be what it is now. ”

Xiao Yun nodded silently: "It's really different from what I remember." ”

The robot exploration team slowly dispersed under their own program drive and the control of the staff in the fleet, so that the range they explored was a little larger. But no matter where they go, the images they get are always the same. It seems that in just a few decades, the planet Raqqa has been completely swallowed by the desert.

Desert everywhere, desert everywhere. There is nothing left above the planet Raqqa except for the desert.

It was at this time. Xiao Yun suddenly remembered something. So Xiao Yun said: "General Emek, I think we should analyze the elemental composition of those deserts now. ”

General Emak nodded. Then he gestured to the staff next to him. The staff quickly carried out the order of the Führer Emerke, so after a while, a table of elements was presented to Xiao Yun.

Xiao Yun held the elemental composition table, his eyes full of shock and disbelief. Xiao Yun looked at those numbers and symbols carefully, and looked at them for a long time, looking at them, and even his body began to tremble slightly, as if what he was holding in his hand was not a piece of paper, but something that could destroy the entire human civilization.

General Emak also walked over and looked at the piece of paper, but did not understand what it meant. So General Emak asked, "Xiao Yun, what do you see?" ”

Xiao Yun let out a long sigh and put the paper on the table, and at the same time, the spirit of the whole person seemed to be sucked away all at once: "General...... Look no further, if I'm correct, at this moment, there are no more enemies on the planet Raqqa, they are all gone. ”

"Gone? Where did they go? General Emak said with some surprise, and picked up the elemental composition table again, and looked at it again, but still couldn't see anything.

Xiao Yun said: "This elemental composition table describes the elemental composition within one meter of the surface of the planet Raqqa, general, you see, the elements that make up these substances are only a few elements such as oxygen, silicon, iron, calcium, etc., so let me ask you...... Is it possible for a natural terrestrial planet to have such a simple composition of surface elements? ”

General Emak didn't quite understand it at first, but when he heard Xiao Yun say this, he immediately reacted: "This is indeed very unusual. So, where did all those vanished elements go? ”

"It's all gone." Xiao Yun muttered, "If I'm not mistaken...... Those elements have been mined by the infinite replication robots and then created into new robots. They have mined all the elements available on the planet Raqqa, and when the planet is no longer worth mining...... They left, heading to the rest of the star systems to continue their search for enough resources. ”

In an instant, Führer Emerck's face also turned pale.

That's the elemental of a whole planet...... While it's unlikely that the elements buried deep underground will be mined by robots, how much will they be in total even if they are just on the surface of the planet? And all these elements and resources are made into robots...... And how much can be made?

At this moment, a staff member hurriedly walked up to General Emek and reported in a low voice: "Report General, after the latest exploration, we have confirmed that the total mass of the planet Raqqa is three billionths lower than it was a hundred years ago. ”

"Three parts per billion." Xiao Yun sighed, "The total mass of the planet Raqqa is about 4.8 times 10 to the 24th power, and 3 billionths is 1.44 times 10 to the sixteenth power...... 4,800 billion robots. Of course, this is not wasted at all, and all the mass is used to replicate themselves, which is certainly not the case, in the actual situation, we also have to calculate the mass loss of the planet itself and the mass consumed by the decay energy, but even if we calculate these things, I can confirm it...... The total number of robot replicas will not be less than two trillion. ”

General Emak turned around with a grim expression, and cast his sharp bayonet-like eyes onto the large screen in front of him. The screen was still showing images from the surface of the planet Raqqa, which had traveled hundreds of kilometers but could see it...... It's still a desert, and nothing has changed.

"Do you know one candy that kids love to eat?" Xiao Yun said quietly, "When I was a child, I liked to eat that kind of candy. It is made up of a hardcore and covered in creamy chocolate, the outer layer of the creamy chocolate is delicious, but the inner hard candy is not very good. So we'll throw away the hard candy inside after eating the creamy chocolate on the outside. ”

"I don't like candy." General Emak said coldly.

"But the robots like it." Xiao Yun also put his eyes on the big screen, and while watching, he continued: "Planet Raka is the candy of the robots. Now that they've eaten all the creamy chocolate, all that's left is the hard candy inside, so they're ...... They threw Planet Raqqa away and left here in search of new candy. ”

"Are you sure this is what the infinite copy bot does?" General Emak turned around and said to Xiao Yun.

Xiao Yun nodded: "I confirm this." Although we don't have direct evidence until now, I would like to ask you, who else has the ability to completely transform a planet in just a few decades, other than infinitely replicating robots? Are we human? You must know that even if we humans want to transform the planet Raqqa to this point, it will take at least tens of millions of humans and nearly a hundred years to do it. And do we humans have such a big move? No. So, apart from infinite copy bots, do you think there will be anyone else? ”

General Emak nodded coldly, then turned around again. Xiao Yun continued, "Now, I think I already know what happened to the flickering of the Raqqa star that we observed earlier. We previously speculated that it was due to the occlusion of some interstellar matter, but now it seems that it ...... It's not interstellar matter that is blocking Raqqa, but an infinite number of trillions of replicating robots...... After completely destroying the planet Raqqa and making it completely useless, they left the Raqqa system in droves for other star systems......"

"Because of the sheer number of them, they obscured Raqqa for a month, and until they all left, Raqqa returned to normal ......" (To be continued.) )
