Voyage of the Stars

Yi Kai even dared to promise in front of Yue Yuan that as long as Yue Yuan could bring him a planet's biosphere, he would be able to produce a life potion with a lifespan of five hundred years within fifty years.

Based on his understanding of Yi Kai's personality, Yue Yuan felt that such words were mostly bragging, but they should be bragging that had been drafted.

Yue Yuan still remembered the old man's tugging expression at that time, as if he was determined that he would not be able to bring him a planetary biosphere.

Just when Yue Yuan was about to introduce the specific details of this life potion to Xu Zhenyi, the internal communicator embedded in the chest of his military uniform suddenly sounded a call tone.

Yue Yuan raised his right hand and clicked on the button on his chest, then heard a woman's voice coming from the communicator.

"Commander Yue, come to the command center quickly. The Hope has received a strange signal."

Manyue eyebrows?

Hearing the familiar Sister Yu, Yue Yuan immediately knew who the caller was.

But with the strange signals or something, could it be another alien civilization? Yue Yuan's heart trembled, why the hell can't humans be given time to develop stably? The threat of 'Silver Mist' is still there, and there is another strange signal, which can't let people live.

"What is a strange signal? Is it impossible to decipher the content or unable to locate the source?" Yue Yuan asked hurriedly without politeness.

"Both, but communications experts say the reason why we can't locate the source is because we have only received the message once."

"Except for Hope, have our detectors at other locations in this galaxy received it?" Yue Yuan asked again.

"Yes, Dr. Zhao Youqin based his judgment on this and said that this signal should be a broadcast signal."

"Okay, I'll be right away."

After Yue Yuan finished speaking, he clicked the button to close the communication, and then looked at Xu Zhenyi: "Professor Xu, do you want to go and have a look together?"

"No, I can't help much with communications. Besides, although superconducting materials have been realized, various optimization experiments still need to be done." Xu Zhenyi put the superconducting materials on the table back into the drawer, and then shook the He shook his head and rejected Yue Yuan's proposal.

He couldn't help or anything. Yue Yuan knew it was Xu Zhenyi's self-effacing excuse, but he didn't force it, so he nodded and said, "Well, then I won't disturb Professor Xu."

After leaving Xu Zhenyi's office, Yue Yuan ordered Long Xiaolin: "Xiaolin, go to the Academy of Sciences and inform Dr. Talya Sinskaya and Dr. Lu Xiaofen to come to the bridge. By the way, if the Academy of Sciences If you can’t find Dr. Lu Xiaofen, go to Dr. Yi Kai’s Life Sciences Institute.”

Talya Sinskaya was one of the few foreigners on the Hope. Before the solar catastrophe, she came to the Callisto base in the name of scientific research cooperation.

Yue Yuan still remembers that the collaborative scientific research project was about quantum information. But after the disaster, Yue Yuan discovered that she was actually a cryptographer. To be precise, it was not a discovery, but Talya Sinskaya herself reported it to the new government after the Hope was completed.

The superficial reason is very simple, that is, she wants to live in a separate cabin belonging to experts.

In fact, when Talya Sinskaya reported the matter, Yue Yuan had some associations with her identity as a cryptologist, but the sun and the earth were gone at that time, so he gave up the in-depth investigation. After all, the investigation It has no meaning anymore.

Talya Sinskaya is a cryptologist, while Lu Xiaofen is a linguist. If the strange signal was an alien broadcast, they might have a use for it.

Deep down in his heart, Yue Yuan actually didn't hope it was a signal from an alien civilization, but no matter how much he didn't hope, he still had to make the necessary preparations.

Some things just don't happen if you want them to happen.

After Long Xiaolin left, Yue Yuan and the two accompanying soldiers rushed directly to the Hope's control center. After turning the elevator several times and passing through dozens of cabin doors, he arrived at the control center.

"What's the strange signal?" As soon as he stepped into the Hope control center, Yue Yuan spoke to the communication experts who were busy at their respective consoles.

"Chief Commander, eighteen minutes ago, the Hope suddenly received a signal with obvious traces of civilization. The signal lasted for 6 minutes and 18 seconds. We are trying to locate its source. However, because the signal is a single time, we are now There is no way to determine its direction yet." Zhao Youqin, who was pointing at the work screen operated by a staff member, turned around and replied.

Yue Yuan walked to Zhao Youqin's side in three steps and two steps, and then also looked at the work screen. He is not a communications expert, and he cannot understand advanced and professional things, but he can understand what the staff are doing.

After looking at it for a while, Yue Yuan probably knew what Zhao Youqin meant by "trying to position".

Because humans have only received one message so far, Zhao Youqin wants to compare the information received by Hope with the information received by human detectors placed in the orbits of other planets in this galaxy, so as to determine the direction of the message through the time difference.

What the staff are doing now is to write algorithms on the computer, and then regard the detectors distributed by humans throughout the planetary system as a receiving array, and then use the signal reception time difference at each point of the array to infer its source.

At this moment, Yue Yuan suddenly saw in his peripheral vision that on a monitor next to him, a wave representing the signal reception display suddenly swayed.

At the same time, the staff member sitting in front of the monitor suddenly shouted: "Director Zhao, look, it's coming again! The signal, the signal is coming again!"

Zhao Youqin quickly ducked behind the staff member, then stared at the display wave.

Yue Yuan also walked over. He saw that the display wave increased and decreased, and the beat was very regular. It was very different from the signal of a pulsar. A discerning person would know at a glance that the source was not a natural pulsar.

All of a sudden, everyone fell silent, and the only sounds left in the command center were the hissing of the signal receiver and the occasional sound of current rectification.

The staff, like last time, used the equipment on the Nozomi to record various characteristics of the signal.

But as soon as I started recording, the signal disappeared. Only a few seconds.

"Last time it was 6 minutes and 18 seconds, why is it only 3 seconds this time?!" Seeing the signal stopped, Zhao Youqin looked to the staff on the left: "What is the time interval between the two signals?"

"23 minutes." The staff member replied immediately.

"The interval is 23 minutes. The first signal lasted 6 minutes and 18 seconds, but the second signal lasted only 3 seconds. Check the records immediately to compare the two signals to see if there is any overlap."

"yes!"

The interval between the end of the last signal and the appearance of this signal is about thirty minutes. If there is a third time, it is most likely some kind of repeated broadcast.

But after waiting for a long time, the third signal did not arrive.

"After comparison, the second half of the first signal is exactly the same." At this time, a staff member shouted.

If there is repetition, it must be from the same source, although I don’t know why the second time is so short.

"Immediately summarize the satellite data and adjust the analog signal array. Two times is enough for us to find the signal direction." Zhao Youqin said to the staff who were integrating the signal array, but as soon as he finished speaking, he patted the staff on the shoulder. Then he changed his words and said: "Forget it, I'll do it."

After the staff gave way, Zhao Youqin sat down in front of the console, and his hands immediately started flying on the keyboard.

As he moved, various data on the display screen immediately flew up and down, and he skillfully typed strings of codes into the array program.

It can be seen that Zhao Youqin is very familiar with these operations.
