Liu Xuan sat in the observer's chair and shouted loudly. The crowd hurriedly gathered around, not paying attention to why the newcomer was sitting in the observer's place, and all looked at the screen.

Li Ping also heard the commotion of moving chairs outside, walked out of the office, and squeezed to the front again, looking at the screen.

On the screen, the characters are still beating, just like Liu Xuan saw, the characters are different from the previous one, it is an essential difference. Just like the French people saw English and Chinese thousands of years ago, although they didn't know and didn't know what they meant, they also knew that they were two languages.

"Observer, determine where and where the information is sent." Li Ping didn't pay attention to the observer at all, and gave the order directly. How could she have thought that it was Liu Xuan sitting on the observer's chair at this time.

"I won't." Liu Xuan said embarrassedly.

Li Ping was stunned when she heard the words, looked down, and found that the observer didn't know when he became Liu Xuan.

"What about the observers?" Li Ping asked helplessly.

"I'm on the toilet, I'm just tired of running and want to sit." Liu Xuan was also embarrassed, feeling like sitting on pins and needles in this place, so he hurriedly stood up.

Everyone laughed good-naturedly, a hilarious scene that is not common in this kind of high-intensity work.

"I'm here." The real observer rushed to the rescue, squeezed in front of the crowd, sat on the chair that Liu Xuan had just let go, and began to use the keyboard to enter commands one by one.

Soon, the answer was displayed on another secondary screen: the sending location was roughly in the constellation Ursa Major. Range-wide galactic broadcasting.

Everyone was silent, which was enough to show that Professor Ma's analysis just now was wrong, they were not tempting, and the advanced civilization that received this news was not afraid of being attacked. Their technological level is similar to that of the Pegasus civilization, and they also control the radio waves very finely within the scope of the galaxy, without the slightest spillover. It is well known that radio waves decay depending on the distance traveled, but it is very difficult to control them so finely, and if it were not for this discovery, people on Earth once thought that this would be impossible.

"There are civilizations that have built barriers, radio barriers." The researcher voiced his guess. In this case, this can only be guessed, if all civilizations are so advanced, the earth is too dangerous, and it is estimated that it has been discovered by other civilizations long ago.

"It's not important right now, it's not a lot of trouble if it's verified, but it's a lot of trouble if the guess fails or the verification is great." Li Ping said.

Liu Xuan next to him also nodded, what Li Ping said was not wrong, this is not difficult to verify, as long as it sends high-intensity radio waves to the universe, but once it is launched, it will be locked by other civilizations. This is not the most important thing, the most important thing is that without the protection of the radio wave barrier, this radio wave is likely to be detected by creatures outside the galaxy, thus bringing a huge disaster to the galaxy, and none of them can afford this consequence.

While they were thinking, the information was still appearing, and in the end, there were a few blanks, but the first two blanks had already been filled, the first blank text was the same as the first interstellar message, and the second blank text was the same as the second interstellar information. After the blank display is completed, the interstellar message is also completed, and no new messages appear.

Everyone withdrew their eyes on the screen, some lowered their heads in contemplation, some looked at Li Ping and wanted to hear his opinion, and some looked at Liu Xuan. Obviously, after verification, Liu Xuan's guess is more likely.

"Can you decipher the meaning of these words?" Li Ping asked an expert in this area again.

"It's difficult, there's so little information, it's hard to do a one-to-one correspondence, and there's no way to explain the specific meaning." Hearing Li Ping's question, the expert said with a sad face.

In this case, let me first talk about my opinion, although this text is different from the previous one, but the text structure of this article is similar to the previous one, such as the paragraph structure. Everyone understands that when translating some text, the paragraph format generally does not change. So I deduced that the two interstellar messages had the same meaning, and they may have been translated by the Ursa Major civilization and published directly in their own words. Li Ping expressed her judgment.

Including Liu Xuan, they all nodded, indicating that they agreed with Li Ping's opinion very much. However, this is not enough, and the most important thing now is what exactly this article is about, and whether it is beneficial or harmful to human beings on the planet, these are difficult to judge.

Everyone was in trouble, even Liu Xuan, who had no new ideas, so he had to scratch his head over and over again, dragging his hair and pondering.

"There's no point in thinking about it now, let's go back to our posts first, and we can communicate with you if we have new ideas. Liu Xuan and I come, and I will lead you to your place. Li Ping came to the final conclusion.

Liu Xuan's tears of emotion were about to come out, and this research maniac Li Ping finally remembered his existence.

Everyone also had no good way, so they all had to disperse.

Li Ping walked in front, Liu Xuan followed, and arrived at a position, next to this position turned out to be Professor Ma Xuan.

"This is the place where cosmic dynamics is studied, and the current main researcher is Professor Ma Xuan." While introducing Liu Xuan, Li Ping pointed to Liu Xuan and said to Professor Ma Xuan: "Professor Ma, this is the new professor of cosmology and cosmic dynamics, Liu Xuan. ”

"I've seen him just now, and I've read his papers, a very thoughtful young man." Professor Ma said with a smile.

"Then you know each other again, I'll go and get busy first." Seeing that the two people already knew each other, Li Ping hurriedly threw Liu Xuan to Professor Ma, and walked to the office to write a report.

Liu Xuan and Professor Ma have met just now, and there is no sense of strangeness, Professor Ma gives Liu Xuan a feeling of familiarity, which may have a lot to do with Professor Ma's lack of pretense.

"We are all experts in cosmic power, I have also read your paper, the writing is really very good, our earth after a thousand years of war, the aerospace industry is actually very backward, you also saw just now, we can only receive the message, but it can't be translated, I'm not afraid of your jokes, the receiver we use now is still the technology of a thousand years ago, it is very backward. Our rockets are still jet engines that use the principle of impulse, carry their own propellant, and do not rely on outside air. The rocket sacrifices too much kinetic energy, so the speed is too slow compared to ideal. Professor Ma first introduced Liu Xuan to the current rocket technology.

Liu Xuan nodded, indicating that he understood that the current aerospace technology is really a bit backward, and it is unreasonable to be worse than the dream speed of light.

"In fact, a few decades ago, there was a better design scheme, using the principle of the atomic bomb, using nuclear fission to produce huge energy to propel rockets and spacecraft, the chief research scientist at that time was Liu Qingyun, limited to reality, just built a nuclear fission aero engine, loaded on the explorer, Professor Liu Qingyun ignored everyone's opposition, he became the first batch of experimenters, but he has not come back until now, and the nuclear fission engine has also lost its manufacturing plan." Speaking of this, Professor Ma sighed in various ways.

"What?!" At this time, Liu Xuan was completely stunned, he didn't expect his father's status to be so high, in his memory, his father was always an amiable person, and he didn't have the aura of a chief researcher.

"These are all secrets, so there is no record in that memorial, but we researchers must know that aviation power still has a high upside, and there have been successful examples in the past!" Looking at Professor Ma like this, it seems that he doesn't know the relationship between Liu Xuan and Liu Qingyun.
