On the earth, people use mobile phones to make calls, and wireless networks to send QQ and WeChat messages seem to be absolutely timely. Only when files are transferred, they need to wait because of network speed and other issues.

However, this does not mean that this is really real-time.

The communication between people is a signal running, and the essence of the signal is electromagnetic wave, the transmission speed of electromagnetic wave signal is the speed of light, in front of the speed of light, the distance on the earth seems very small, even if it is a call separated by an ocean, it sounds They can all communicate as if they are face-to-face without delay, and the time it takes for a little electromagnetic signal to run is not even felt by the fragile receptors of human beings.

However, it doesn't work under the starry sky scale.

Everything that happened a light-year away came to the earth carrying information and was observed by people. This time would take a whole year.In other words, if two people are talking with each other a light-year apart, and the two people are talking at the same time, then both parties in the call must wait a year before they can hear what the other person is saying, and when they hear the reply again, then It will take another year, unless quantum or hyperspace communication technology is used, and this technology may be applied to the transmission of information between the two sides of the interstellar, but it is difficult to apply to the detection of cosmic space.

And because of this, although the fleet has already mastered a certain quantum communication technology, it cannot be applied to the exploration of interstellar space. Therefore, astronomical observation and reconnaissance of the earth will also be greatly restricted.

This transition was discovered 17 billion light-years away, and the information feedback was received four days ago, which was the last day of the previous year, the day before Proxima Centauri's first spacecraft appeared.

Of course, we have to take into account the concept of space we just talked about. It will take at least 14 to 15 days for the information to run through the seven billion light-years to the earth.

This means that Proxima Centauri appeared in the outer ring space of the solar system at least eighteen days ago!

They... have already arrived in a leap.

When the various observatories submitted the data, they had already checked and determined that they were not the ghost ship fleet that entered the solar system from the direction of the neighboring star.

And combining all the above, the biggest problem right now is...

Where is this Proxima fleet now?

It has arrived in the outer space of the solar system 18 days ago, and the surveillance network of any extraterrestrial space fleet has not been disturbed in these 18 days. Then, they may appear anywhere!

Su Ran only felt a cold chill rise from his back.

Still the time is too short, too short.

He only has space to arrange a line of defense between the earth and the moon, and outer space can barely take care of it a little.

And if you want to really make the entire solar system cover your own "eyes", this has not been possible in a few years or even decades, because the area is too large and there are various stars, and the space is like an iron barrel. That is not something that can be done easily.

Fortunately, this icy feeling was quickly driven out by Su Ran. He took a deep breath and said: "To all countries and observatories, I hope they can continue to search based on this discovery, whether it can be or not. , Try to find their tracks."

The Proximity Star Fleet is very careful. At least from the current feedback, according to the Earth’s 17 billion light-years away, the jump was their last jump, because a little closer is the area of ​​the solar system, which is obvious. , They are deliberately "hiding" themselves, and as long as they want to hide and enter a silent state, it is almost impossible to discover with the pure telescope-like observation level of the earth, but Su Ran will not give up any of them. The details, even if it knows, it is almost impossible to find them by observation.

Searching where they came from, the far-end jump information didn't even reach the earth even while running on the road, and they couldn't find their place anymore.

but……

This information is not useless.

Proximity made peace on the bright side, but in the dark it was moving a huge fleet, even going around a large circle, cautiously entering the surrounding areas of the solar system, the purpose of which is almost self-evident.

The atmosphere in the bridge is not bad, because the strength of the fleet and the composure of the commander are all regarded as serious by everyone.

At this time, Li Yilan said: "Your Excellency, the Russian Federation, China, the United States and other major powers and large survivors all hope to convene an emergency global joint meeting, and hope to..."

Su Ran said: "I know, start the remote conference mode, I will go in a few minutes later-is the information passed to Old Qiao and Lin Yuandong? I want to connect to the communication."

Li Yilan nodded and immediately responded.

Su Ran started to operate and connected the two battle group commanders of the third and fourth cloud city battle groups that were in the orbit of Jupiter.

There is no picture, only sound.

A slight change occurred in Lin Yuandong's voice, a little nervous, and he said: "Is it possible that this is a cautious move by the Proxima Fleet? Just like we are cautious about them, they just keep one hand against us?"

The logic of this point is logical. Su Ran also thought of this for the first time. After all, from the situation of the previous three days, the Proxima Fleet is quite cooperative, and judging from the caution of alien civilizations, they are also on guard. It is not impossible to land on the earth...

Then...

Su Ran coldly said: "Well. We can understand it this way, but I want you to be ready to fight at any time. Over the past three days, we have scanned the eleven spaceships of the Proxima Ghost Ship fleet and accumulated a lot of The important data of the enemy ships, although they are not considered as knowing oneself and the enemy, but...I hope that if war starts, you can eat this ghost ship fleet in the shortest time!"

Lin Yuandong and Qiao Xiangchen, who are far in the orbit of Jupiter’s two flagships, heard Su Ran's cold and solemn voice, and they both said in unison: "Receive! Your commander!"

Su Ran immediately cut off the communication. He intended to quickly access the global joint conference, but he was silent for a moment, but he contacted the spore life still in the ground laboratory.

The representative sent by Spore Life is still Su Ran’s "old acquaintance" Liu Tingting. She has almost no expression on her face. As a civilized partner, Su Ran has always shared the news about the Proxima Fleet with them. Therefore, At this time they also knew the situation, and Su Ran asked straightforwardly: "What do you think?"
