"Why!" Gu Chen was the first to disagree, the Pluto base is too big, just its ecological balance circle is a huge treasure trove, many of Gu Chen's research has just begun, and they have only been coming to Pluto for more than a month, so they have to return in such a short time, is this a joke?

Lin Guodong and Mo Liwen also showed very puzzled expressions, in their opinion, continuing to stay at the Pluto base was the best choice. Now that the American Hades and the Russian's Starry Sky have been expelled from Pluto, and no one is disturbing the entire base, isn't this a good time to dig into the secrets and technology of the base?

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

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

"Sue us? Professor Luo, what happened? Gao Jian keenly felt that something big must have happened, and hurriedly asked.

Su Yichen hesitated, and finally decided to tell everyone the truth. He walked straight to the three-dimensional star map and stretched out his hand to point to the coordinates on the star map: "This is a coordinate, about 16 light-years away from our solar system, and its position is in this ...... when this coordinate first appeared. ”

Su Yichen stretched out his finger and nodded in an area in the direction of the Southern Cross, and then continued, he had already arrived here when he appeared for the second time. His finger moved in the direction of the solar system, lingering in the second position.

Except for Gao Jian, all of the people present were experienced astronauts or scientists, although the entire star map was only a part of the Milky Way, or only a star map of the solar system and several galaxies around the solar system. However, its diameter is almost 300 to 320 light years in practice, which is a distance that is almost impossible for humans to cross.

And although Su Yichen's finger movement was very small, he was extremely shocked in the eyes of others, because according to the proportion of his movement, it was a distance of dozens of light years, what does this mean? Just think about it and you'll understand.

"When was the first time? When was the second time? Lin Guodong pressed the panic in his heart and couldn't help asking.

Su Yichen said two time frames, when his voice just fell. Lin Guodong was stunned, and Mo Liwen and Gu Chen beside him also stared at him with incredible eyes.

"It's true, system!" Su Yichen finally shouted, and let the system simulate the change of the coordinate route. As soon as the order was given, the entire star map underwent subtle changes, and if you didn't pay attention, no one would notice that the positions of the planets, stars, and small galaxies in the star map had changed slightly. The entire universe, including the Milky Way, is constantly in flux, with planets and stars orbiting each other, and the distance, position, and angle between small galaxies and small galaxies will always change. Even a behemoth like the Milky Way.

This change is so small that it may take decades, centuries, or even thousands of years for humans to detect the movement of the stars from their observations from the Earth. However, in the intuitive direction of the three-dimensional star map, this transformation is more obvious. Of course, this also requires extremely professional people to see, and almost all of the people present are professionals.

Under the control of the base system, the coordinates clearly show its trajectory. After the entire route was visually displayed in the star map, the star map returned to its original state. At this moment. Lin Guodong and the others were all silent, judging from Su Yichen's narration and the display in the star map, it was already obvious what this coordinate meant.

"A year and a half to go...... Less than two years ...... at most. ”

It is easy to calculate the approximate time of the arrival of the visitors of the Southern Cross in the solar system, who is the other party, and what purpose are they coming to the solar system? Was it passing by or accidental, or was it just for the solar system including the Earth? No one knows any of this. But in any case. It's a big event, and it's even more terrifying than the Pluto base they're in. After all, the Pluto base is just a base left over from the Rand civilization, but the visitors from the Southern Cross that flew to the solar system are real alien civilizations.

"Could it be that Ike of the Rand civilization has returned?" Morlivan couldn't help but guess, but as soon as he said this, he shook his head. If it's Ike back. Then it is absolutely impossible for the base system to react like this, this situation Su Yichen has mentioned before, it is precisely because the base system has detected the coordinates of the visitors flying towards the solar system of the Southern Cross, which will warn them.

"Maybe the other side is friendly ......." Gu Chen whispered, but as soon as he finished saying this, he shook his head. Maybe who can say this kind of thing clearly? Friendly? What does it mean to be friendly? The history of mankind is a history of war, and the law of the jungle is the rule of the earth's civilization, and in the vast universe, who can guarantee that the civilization of the universe is not like this?

Moreover, there is never a friendly outcome without a balance of power, and peace is based on the premise of a balance of power on both sides. Just like when Columbus discovered the New World, the Europeans were also tempting and cautious in dealing with the backward Indians at first, but when they found 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 blood and tears of the Indians, who owned the entire American continent and had a population of hundreds of millions, but what about now? It's just a small area like captivity, and it's also called a "protected area".

This is the cruelty of human beings to human beings, and it can be like this for the same race, let alone a different race? Maybe some people will do that only a few hundred years ago, and now that human civilization has developed to this day, this cruel thing has disappeared. If you really think that civilization is a panacea for war, greed and conquest, then it is too naïve, in today's society, although this kind of thing is almost invisible on a large scale, but human nature has not changed, and even because of the development of society and the progress of science and technology, people better disguise their desires, and use various high-sounding reasons to achieve the ultimate goal.

In these respects, no one can predict what the visitors of the Southern Cross will bring to the solar system and to the earth. At this moment, they also understood the reason why Su Yichen decided to return as much as possible, and in this case, there was still some opportunity to return immediately, and rush back to Earth with the technology, materials, and other items obtained from the Pluto base, so as to prepare for the upcoming uninvited guests.
