Earth Era

The Raqqa planet is quietly suspended tens of billions of kilometers away from the fleet. It is like a lost world, full of endless mystery and darkness.

There is a thick cloud layer on the Raqqa planet, which is even thicker than the cloud layer above Venus in the solar system. This made it impossible for the probes launched by General Emock to obtain data on the planet's surface at all. In this case, sending robots to land on planets is the most appropriate approach. If it is determined that there is no danger on the Raqqa planet after robot exploration, it will not be too late to send humans to land at that time.

A robot formation was launched from a spaceship and embarked on a dark journey. It will spend more than ten days sailing to the planet Raqqa, and then reveal the truth hidden by this heavy cloud to the people waiting here.

Xiao Yun and General Emock saw the information transmitted by these robots in the battle command hall together. Raqqa's surface is largely devoid of visible light, so these robots were photographed using infrared light, which resulted in images that always had an eerie hue that looked like something that was old and lost. Old video footage in true color is average.

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

Whether it is the rolling mountains, the vertical and horizontal ravines, and the strong winds that can blow away boulders, these things are all familiar to Xiao Yun. There is only one thing... Although the mountains are still mountains, and although the ravines are still ravines, their appearance is somewhat different from what Xiao Yun has seen before.

Of course, the mountains towered high above the earth, but the mountains above the Raqqa planet did not look like that at the moment. If I have to describe it, it is... they seem to be piled up, not pierced from under the earth. Xiao Yun tried hard to think of adjectives in his mind, and after a long time he suddenly remembered that these mountains are actually on the earth. The dunes in those deserts are about the same.

The same is true for those ravines, they are no longer sharp, but become very gentle, like small ditches blown out by the wind in the desert. And those lands...they are no longer one. When the robot points its own camera up close to them. Xiao Yun could even detect those granular structures.

General Emock asked Xiao Yun: "Although I don't know much about the Raqqa planet, I probably remember... Raqqa planet seems to be a very wet planet with very rich landforms, it seems that it is not It's like that."

Xiao Yun nodded silently: "It is indeed different from what I remember."

Driven by their own programs and controlled by the staff in the fleet, the robot exploration team slowly spread out the distance, so they explored a larger range. But wherever they go. The pictures they take are always like this. It seems that in just a few short decades, the Raqqa planet has been completely swallowed by the desert.

Deserts are everywhere, deserts are everywhere. Except for the desert, there is nothing on the planet Raqqa.

At this moment, Xiao Yun suddenly remembered something. So Xiao Yun said: "General Emock, I think we should analyze the elemental composition of those deserts now."

General Emock nodded, then gestured to the staff next to him. The staff quickly carried out the order of the head of Emerk, so after a period of time, an element composition table was presented in front of Xiao Yun.

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

General Emock also came over and looked at the piece of paper, but he didn't understand what it meant. So General Emock asked, "Xiao Yun, what did you see?"

Xiao Yun let out a long sigh and put the piece of paper on the table at the same time. The whole person's energy seemed to be taken away at once: "General... don't look for it anymore. If I guess right, at this moment, there are no enemies on the Raqqa planet. They are all gone."

"Let's go? Where did they go?" General Emock said in surprise. He picked up the element composition table again, and looked at it again, but still couldn't see anything.

Xiao Yun said: "This element composition table describes the element composition within one meter of the surface of the Raqqa planet, general, look. The elements that make up these substances are only a few elements such as oxygen, silicon, iron, and calcium. Then I ask you... a natural terrestrial planet, is it possible that the composition of its surface elements is so simple?"

General Emock didn't quite understand it at first, but when he heard Xiao Yun's statement, he immediately reacted: "This is indeed very unusual. So, where did all the disappeared elements go?"

"It's all gone." Xiao Yun murmured, "If I'm not mistaken... those elements have been mined by the infinite replica robots, and then made into new robots. They will use all available resources on the Raqqa planet. All of the elements of the planet are exhausted, and after the planet is no longer worth mining...they leave, go to the rest of the star system, and continue to find enough resources."

At this moment, the face of the head of Emerk also became ashen.

That's the elements of a whole planet... Although those elements buried deep in the ground are unlikely to be mined by robots, how much will their total content be even if it's just the surface of the planet? And so many elements and resources, if they are all made into robots... how many can be made?

At this time, a staff member hurried to General Emock's side, and then reported in a low voice: "Reporting General, after the latest detection, we confirmed that the total mass of the Raqqa planet is ten years lower than it was a hundred years ago. three millionths."

"Three billionths of a billion." Xiao Yun sighed, "The total mass of the Raqqa planet is about 4.8 times ten times the twenty-fourth kilogram, and three billionths is 1.44 times ten times the kilogram. The sixteenth kilogram of , and if a robot has a mass of 3,000 kilograms, the total mass of 3/1000000000000000000000000000000000000000000000000000000 Inc can make... 480000000000 robots. Of course, this is no waste at all, and All the mass is used in the case where they replicate themselves. Of course, this is not the case in reality. In the actual situation, we also need to calculate the mass loss of the Raqqa planet itself and the mass consumed by the decay energy, but even if the calculation is These things, I can also confirm ... the total number of robot replicas will not be less than two trillion units."

General Emock turned around with a grim look, and projected his sharp bayonet-like eyes onto the big screen in front of him. The screen is still playing the pictures detected by the detection robots on the surface of the Raqqa planet. Although the robots have walked hundreds of kilometers away, what they see... is still a desert in the sky, and there is no trace of it. Variety.

"Do you know a kind of candy that children like to eat?" Xiao Yun said quietly, "I liked that kind of candy when I was a child. It is composed of a **** and covered with creamy chocolate. The outer layer is creamy. The chocolate is delicious, but the hard candy on the inside is not. So we throw away the hard candy on the inside after we eat the creamy chocolate on the outside.”

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

"But the robots like it." Xiao Yun put his eyes on the big screen, and continued to say while watching: "Laka planet is the candy for the robots. Now, they have finished eating the creamy chocolate. , only the hard candy was left, so...they threw away Raqqa and left to find new candy."

"Are you sure this is what the infinite replica robot did?" General Emock turned around and said to Xiao Yun.

Xiao Yun nodded: "I confirm this. Although we have no direct evidence until now, I would like to ask you, besides the infinite replica robot, who else has this kind of experience in just a few decades? The ability to completely transform a planet from within? We humans? You must know that even if we humans want to transform the Raqqa planet to this level, we need to invest at least tens of millions of humans, and it will take nearly a hundred years to do it. And do we humans have such big movements? No. So, do you think there will be anyone other than infinite replicating robots?"

General Emock nodded coldly, then turned around again. Xiao Yun continued: "Now, I think I already know what is going on with the scintillation of the Lakka star we observed before. We previously speculated that it was due to the occlusion of some interstellar matter, but now it seems... It is not interstellar matter that blocks Lakka, but the infinite replica robots that number as many as several trillion... After they completely destroyed Lakka and made Lakka completely worthless, they formed in groups. The team left the Raqqa system and went to other star systems..."

"Because there are too many, they blocked Laka Star for a month. Until they all left, Laka Star returned to normal..." (To be continued.)
