After greeting everyone warmly, the research room returned to its former calm, here, the most excited people are the people who study the lightspeed engine, as the father of the nuclear power engine, Liu Xuan's must have a high attainment at the level of space engines.

Liu Xuan did not participate in the development of the light-speed engine for the first time, on the one hand, he also had to learn relevant knowledge, on the other hand, he did not know which faction he wanted to favor now. In the long run, the light-speed engine is an inevitable product, but in terms of the current practical situation, it is most practical to study the fusion and fission of all matter. The few questions he asked just now are all important problems in the study of the speed of light, and if they are not solved, how to build a light-speed engine?

Li Ping and Liu Xuan were now surrounding the observers, asking about the news of the mysterious agreement for a hundred years. The observer silently called up more than a dozen new messages, and judging by the appearance of this text, it was sent by the civilization that compiled the agreement.

"In addition to the original text of the agreement, the first message was received in the year you froze, and then several letters were received from time to time, and the longest time between the two letters was twenty years, and the closest to the two letters was only two days." The observer looked at the computer records and explained to the two men.

"Even though I couldn't tell what they were writing, I could feel their urgency. They seem to need something from us, but we don't understand what they mean. Liu Xuan sighed lightly, he could feel the impatience, confusion and even despair between the lines.

"It's been almost five years since the last message, and five years ago, within a month, we received three messages, the last two being the penultimate and the third-to-last." The observer pointed to the two messages he had said, with an old finger.

The penultimate and penultimate letters are both very short, and it seems that the person sending the message is very urgent. Still couldn't understand the meaning, Liu Xuan had to move his eyes to the last message.

The message was very long, even longer than the content of the first agreement, and the font had changed, the text was still the same, only the font had changed, like the difference between regular script and line script. You can even see the smeared part of the message.

The part that smeared?! Liu Xuan was shocked.

"Is this last letter a special format?" Liu Xuan asked the observer.

The observer glanced at Liu Xuan suspiciously, entered a simple command on the keyboard, and the format of each message was displayed, and sure enough, the format of the last letter was different, and it turned out to be a picture format. This is enough to show that the final message was handwritten by a person, and then forcibly launched regardless of the consumption of energy.

As we all know, the space occupied by pictures is far larger than that of plain text documents, and even if there is a wormhole between the stars, in order to maintain the integrity of the information, it is necessary to consume a lot of energy. In order to send back the news of the agreement, the Earth Federation requisitioned ten large hydroelectric power stations, and I heard that in the end, because the load was too large, the antennas were destroyed, so this time the news was sent.

What does this civilization want to illustrate by spending a lot of energy to send this picture message to the universe? Liu Xuan faintly felt that it was probably inseparable from the advanced civilization in the universe.

"We have actually studied these things for a hundred years, but without the other party's reminder, we don't know what each character represents, and looking at this distorted character, we don't even know if it's hieroglyphs." The observer reluctantly said that although the earth technology has developed well, there is no place to start in such an analytical language.

Liu Xuan also understands that the languages of the world are roughly divided into three categories, namely epigraphs, ideograms, and phonetic characters. In today's Asia, most of the characters are written in epigraphs, or hieroglyphs. Most of Europe and North America use phonetic scripts, and without long-term communication, it is difficult to translate the specific meaning of phonetic scripts.

Liu Xuan rubbed his head and tugged at his hair from time to time, there was no way to study these things. They all know the importance of this information, but they can't crack it. It's like a chest full of treasures, but you don't have the keys to the chest.

Thinking to no avail, Liu Xuan gave up starting from this aspect, and after saying goodbye to everyone, Liu Xuan and Li Ping walked out of the research room. Liu Xuan didn't say where he was going, he just walked with his brows on his brows, thinking about something. Seeing Liu Xuan's appearance, Li Ping didn't ask any questions, and the two of them wandered the streets of this dungeon like this.

"Do you know where the other lab is? It is a laboratory that studies the fission and fusion of all things. Liu Xuan stopped and asked Li Ping beside him abruptly.

Li Ping nodded and said that she knew that before Liu Xuan woke up, she had already investigated these things. She knew that Liu Xuan was very interested in these things.

Without delay, Liu Xuan followed Li Ping to the magical elevator again, but this time the number entered changed, and it didn't take long for the elevator to stop running and the door opened.

Except for the different personnel, the layout of this research room is the same as that of my original research room. All the researchers just glanced at the two newcomers, and they didn't stop their busyness.

No one paid attention, Liu Xuancai had more time to observe this research room carefully, compared with his own research room, the number of people here was significantly larger, and all the people in this research room were studying this problem, which was essentially different from Liu Xuan's research room. Liu Xuan's original laboratory also had the task of observing the universe.

Bypassing all kinds of research tools, Liu Xuan and Li Ping walked straight to the office in the depths of the research room, they both knew that the person in charge of the research room was generally in the office, just like Li Ping back then.

There was indeed a man in the office, not young or old, who looked to be about fifty years old, wearing a simple gray shabby leather jacket, with his hair and beard tousled, sitting in front of a high-performance computer and doing a simulation experiment. Liu Xuan is not surprised by this, many researchers are addicted to research all day long and cannot protect themselves, and they don't care about their appearance at all.

There was no door in this office, so Liu Xuan had to knock on the wall and make a knocking sound, indicating that someone was coming.

Fortunately, the person in charge was not obsessed with his own research and couldn't extricate himself, and after hearing the voice, he invited Liu Xuan and the others to the office as soon as possible.

reacted the same as everyone else, after hearing that Liu Xuan was the chief designer of the nuclear fission engine, he stretched out two old hands that did not match his age and hugged Liu Xuan, as if he was afraid that Liu Xuan would run away. It seems that every research room has received the news of Liu Xuan's awakening.

"I've actually decided to help you study this problem this time, I've already seen the speed of light laboratory, and I feel that it's more practical to study the energy problem first, and the speed of light is still difficult for us to achieve now." Liu Xuan went straight to the point and directly stated his attitude and purpose.
