"Why!" Gu Chen was the first to disagree. The Pluto base is too big. Its ecological balance circle is a huge treasure house. Many of Gu Chen's research have just begun, and they only have been to Pluto for more than a month. They have to return in such a short time. Is this a joke?

Lin Guodong and Moliwen also showed very puzzled expressions. In their opinion, it is the best choice to continue to stay at the Pluto base. ︾ Now, the American Hades and the Russian Starry Sky have been expelled from the Pluto field, and no one has disturbed the entire base anymore. Isn’t this a great time to dig out the secrets and technology of the base?

Gao Jian pondered slightly. He guessed that Su Yichen's decision must have his intention, but what was the intention? Thinking of this, he couldn't help but turn his inquiring eyes to the other party.

"Tell them, if it were me, I would have reacted like this." Just as Su Yichen was hesitating whether he wanted to tell the truth to Lin Guodong and the others, Luo Yan said softly.

"Tell us? Professor Luo, what happened?" Gao Jian keenly felt that something must have happened, so he asked quickly.

Su Yichen hesitated for a while and finally decided to tell everyone the truth. He walked straight to the three-dimensional star map and pointed at the coordinates on the star map: "This is a coordinate, about 16 light years away from our solar system. From the first time this coordinate appeared, its position was here..."

Su Yichen stretched out his finger and pointed at an area in the direction of Southern Cross, and then continued to say that he had already arrived here when he appeared the second time. His finger moved his fingers towards the solar system and stayed in the second position.

Except for Gao Jian, the people present are experienced astronauts or scientists. Although the entire star map is only part of the Milky Way, or just a star map of several galaxies around the solar system and the solar system. However, its diameter is actually calculated to be about 300 to 320 light years, and this distance is almost unsurpassable for humans.

Although Su Yichen's finger movement was very small, he was extremely shocked in the eyes of others, because according to the ratio of his movement, it was a distance of dozens of light years. What does this mean? Just think about it carefully and you will understand.

"When is the first time? When is the second time?" Lin Guodong suppressed his fear and couldn't help asking.

Su Yichen spoke two time ranges. As soon as he finished speaking, Lin Guodong was shocked, and Mo Liwen and Gu Chen beside him were also staring at him with incredible eyes.

"This is true, system!" Su Yichen finally shouted, asking the system to simulate the changes in the coordinate route. As soon as the command was issued, the entire star map had undergone subtle changes. If you don't pay attention, no one would notice that the positions of the stars and small galaxies in the star map have undergone extremely slight changes. The entire universe, including the Milky Way, are constantly changing. There are orbits between planets and stars, and the distance, position, and angle between small galaxies will continue to change. Even behemoths like the Milky Way are the same.

This change is extremely small. It may take decades, hundreds of years, or even thousands of years before humans can discover the movement of stars from the earth's observation. But in the intuitive direction of the three-dimensional star map, this change seems more obvious. Of course, this also requires extremely professional people to see, and almost all the people present are professionals.

Under the operation of the base system, the coordinates clearly show its movement trajectory. After the entire route is displayed intuitively in the star map, the star map returns to its original state. At this moment, Lin Guodong and others were all silent. Judging from Su Yichen's narration and the display in the star map, what this coordinate means is obvious.

"There are one and a half years left... less than two years at most..."

It is easy to calculate the approximate time for visitors from Southern Cross to arrive in the solar system. Who is the other party, and what purpose they came to the solar system? Was it passed by or by chance, or was aimed at the solar system and the earth? No one knows these. But no matter what, this is a big event, and this event is even more terrifying than the Pluto base where they are. After all, the Pluto base is just a base left by the Rand civilization, but the Southern Cross guest flying to the solar system is a real alien civilization.

"Can Ike of the Rand civilization be back?" Moliwen couldn't help guessing, but he shook his head as soon as he said this. If Ike was back, then the base system would definitely not have reacted like this. Su Yichen had mentioned this situation before. It was because the base system monitored the coordinates of the visitor flying to the Southern Cross into the solar system that they would warn them.

"Maybe the other party is friendly..." Gu Chen said softly, but as soon as he finished speaking, he shook his head. Maybe who can explain this kind of thing clearly? Friendship? What is friendship? Human history is a history of war. The survival of the weak is the rule of the earth's civilization, and who can guarantee that the universe civilization is not like this in the vast universe?

What's more, there is never a friendly result without the comparison of power. Peace is based on the balance of power between the two sides. Just like when Columbus discovered the New World, Europeans initially dealt with each other with temptation and caution against the backward Indians, but after finding out the details of their opponents, the massacre of the Indians began. The history of the great development of the New World is actually the history of the blood and tears of the Indians. At that time, they had the entire American continent and a population of hundreds of millions, but what about now? They were just constrained in a small area like being held in captivity, and were also called "protected areas".

This is the cruelty of human beings to human beings. For all the same races, let alone foreign races? Perhaps some people will do it only a few hundred years ago. Now that human civilization has developed to this day, such cruel things have disappeared. If you really think that civilization is the magic medicine that leads to war greed and conquest, then it would be too naive. In today's society, although such things on a large scale are almost gone, human nature has not changed. Even because of the development of society and the progress of science and technology, people have better concealed their own ** and achieved their ultimate goal with various high-sounding reasons.

From these aspects, no one could predict what the visitors from Southern Cross would bring to the solar system and the earth. At this moment, they also understood why Su Yichen decided to return as soon as possible. In this case, there were still some opportunities to return immediately. They brought the technology obtained from the Pluto base, materials, and other items to return to the earth to prepare for the uninvited guests.
