Silence, still silence, even if Liu Xuan has already explained his thoughts, the three people around him still don't have any response, they don't know what they are thinking, even if it is Liu Xuan, they can't figure out their respective thoughts, for the first time, Liu Xuan felt the estrangement between himself and them for the first time.

You must know that the time when the four of them have known each other, plus the time of hibernation, is still half a century long, if this is put on ordinary humans, it has been a matter of most of their lives, and the four of them have been discussing this plan, even in the invasion of the Starfall civilization, even when the mysterious civilization is about to conquer the earth, they still have not given up their dreams, Liu Xuan can always guess their hearts, as technicians, their hearts are not so difficult to understand.

But now, Liu Xuan, who didn't speak earlier, made Liu Xuan, feel their indifference, is this a sacrifice for his life? Liu Xuan can't say for sure, he has always had his own fighting spirit, even in the most difficult times, when he thinks of his father and those mysterious messages, Liu Xuan will be full of fighting spirit.

It's the same at this time, he doesn't die here, he also has a lot of things that have not been solved, you know, in life, his two biggest secrets are unsolved, even if Liu Xuan dies now, Liu Xuan is absolutely dead, his past has determined his future is very difficult.

In this way, the four of them still have a lot of secrets, each of them has a past experience, in fact, they didn't tell the other person, maybe when they passed through the wormhole, each of them reminisced about their past again, and it was they who would become like this.

Everyone has their own past, they may have used their own research, their dreams have numbed themselves all the time, but the best anesthetics in the world have a time limit, and they are no exception.

Once again, they had to confront their past. Although Liu Xuan didn't know what their respective pasts were, in their state, Liu Xuan could guess that it was definitely not good, even worse than Liu Xuan's past, and the most difficult thing was that there was no way to make up for those unhappiness, they were all old regrets.

There is still time, and now their exploration is basically maintaining its own inertia to move forward, if you want to turn back, you just need to restart the thrusters, for them who have been sailing for half a month, there is still enough time to change their course, a day or two, they are still acceptable.

Liu Xuan was also thinking about how to rekindle their hope of survival again, Liu Xuan really couldn't think of it, maybe he could still rely on the idea of saving the earth's civilization to paralyze himself, but now, after really recognizing the status quo, they finally collapsed.

That's their unique way of collapsing, no yelling, no

also crying and making trouble, only silent, no matter how they communicate, they come back silently, this situation is the most difficult for them, Liu Xuan has no way to let them hear his words in their heads.

Whether the earth civilization exists or not, they are not sure, if judged according to the worst situation, the four of them may be the last remnants of the earth civilization, after all, the wormhole distorts time, in the wormhole, they have spent too long, although they do not have any changes or even feelings, but in space, time has indeed passed.

"Everyone, I know that you have no fighting spirit now, but we still can't die, have you forgotten, the first time we met, we saw those farmers outside the suburbs, they are self-sufficient, like the so-called peach blossom paradise, but this is only temporary, once the last crisis on the earth occurs, and there is no way to solve it, do you think the government will help them to evacuate?"

"I know that each of you has a bad past, but even the worst things happen on the earth, and in the same way, the best things happen on the earth, the earth is our memory, our eternal home, don't we have the responsibility and obligation to save him?"

"Take 10,000 steps back, you have no fighting spirit for the next step, and you all want to die, but is the last sight you see at ease in the vast darkness? Look outside, do you really want to sleep in such an environment for a long time? Even if we are going to die, we will be on the earth! ”

Liu Xuan breathed a sigh, Liu Xuan, who had not made any drafts, and had not even said a lot in front of the crowd, was now speaking like this with fighting spirit, this was definitely the first time Liu Xuan had spoken like this, since he was a child, Liu Xuan stood in front of many people and spoke passionately, never before.

Even back then, Liu Xuan discovered a lot of things, when he stood in front of many people in the Federal Assembly to speak, he didn't look like this, and when he talked to his friends, Liu Xuan was also like this for the first time, but the effect was still quite good, after Liu Xuan finished speaking, he habitually patted the table, and the other three people finally turned their eyes over.

"We all understand what you said, but we are fed up with this environment, we are indeed paralyzing ourselves, the original expectation of deep space, now it has become the deepest fear in our hearts, that emptiness, that feeling of loneliness almost makes me crazy. I don't dare look at the starry sky behind you, it's no different from a dark hell to me. Xuan Mu just glanced at Liu Xuan, then quickly retracted his gaze, looked at his teacup, and said.

Liu Xuan realized that the position of his seat was actually quite wonderful, he happened to be facing away from the largest window above the "Discovery", and there was endless darkness outside, he couldn't see these things, but when the other three people looked at him, they would definitely see it.

It's like what Liu Xuan thought

In that way, the three of them, among which Xuan Mu and Wang Meng were the most serious, Qin Ming was still a little better, after all, Qin Ming and Liu Xuan had seen too many such scenes on the earth fortress at that time, they both had a unique deep space phobia, which looked so beautiful on the earth, and the starry sky that made them fascinated was now the source of their fear.

It is actually normal for Qin Ming to have such a situation, although he and Liu Xuan have been in space for a long time, but what is different from now is that the real situation at that time, they all spent time on the earth fortress, although there is such a starry sky all around, but behind them, it is a huge earth, and the blue earth glows with a bright blue light, which is the reason why they did not show such a situation on the earth fortress.

Everything is different now, no matter which side they look at, there is actually nothing there, not to mention the planet that emits blue fluorescence like the earth, and even a huge planet, there is no planet where they can stay, which is what makes the other three people so afraid.

Liu Xuan has seen many photos of the starry sky brought by his father since he was a child, and he has had such an awareness since he was a child. In fact, even he has a dullness in his heart, but the other three people feel even stronger.

If Liu Xuan really describes it, this is actually a feeling of missing, missing is related to time, but it is also related to space, under the long-distance separation, the long-distance separation, the long-term separation will also double the growth, they don't know how far away from the earth, this is the main reason why their thoughts are multiplied.

Liu Xuan deeply understands the feeling of longing, his heart is like a knife, a very painful look, but there is no way to relieve it, he makes his whole body uncomfortable all the time, when he was young, Liu Xuan often had such a feeling, Liu Xuan at that time, he was still young, and he lived in school to study, and he actually felt very deeply about such a feeling.

Liu Xuan's initial thoughts were still not wrong, the three of them actually really lacked hope, Liu Xuan lived in school when he was a child, and had a fixed holiday time, as long as it was that time, Liu Xuan could go home, and the thoughts would naturally disappear. But now they don't have a fixed time to return, which is why they are so miserable.

Liu Xuan couldn't think of a solution to this matter, their voyage couldn't go on, they weren't children anymore, and they couldn't be confused with simple lies, Liu Xuan himself was not a psychological expert, and he didn't know much about this aspect. He's really helpless.

Then there is only one last way, that is the method that Liu Xuan just proposed, return! As long as they are sure to return, they still have their own destination, and in half a month of returning, they can also repair the antimatter shield outside, return home, and go back, this is their new hope.

"Let's go back and sail like this

Go, there is no goal, it is indeed quite painful, endless darkness, oppressing us, although we did not get any other technology through the wormhole this time, but it also proves the feasibility of our technology, maybe waiting for more people can pass through the wormhole, and more things will be discovered! After Liu Xuan finished speaking, he didn't wait for other people's opinions, and directly called up the operation interface and began to confirm the return.

The other three people didn't say they agreed, nor did they say they disagreed, they just watched Liu Xuan skillfully call up the operation interface, modify various settings, and start to prepare for the return flight. Liu Xuan did it very carefully and slowly, so that even if someone objected, Liu Xuan could stop quickly, although this is unlikely.

Liu Xuan actually understands very well that these three people are all people who want to save face, after the conversation just now, Liu Xuan has already figured out their minds at one time, although they are still holding on, but the opinions on returning to the voyage have been written on their faces, and they have revealed it in their eyes.

It's like having some feelings, even if you close your mouth, that feeling, that feeling, that kind of decision will be like tears, appearing in your eyes, flowing out, so that other people can understand that he has such feelings, although he is absolutely unspeakable, and his eyes are the most difficult to imitate and the most difficult to hide.

Liu Xuan carried out step by step quite carefully, they have been sailing for a month, and the distance traveled is definitely quite far, in such a short time, they have sailed so far, which also shows the excellence of the new propulsion system built by Liu Xuan. If nothing else, the earth is already starting to use such things in large quantities.

The extension of the sailing distance also brings a big problem, after all, this is in the space of the universe, the space is so large, it is not something they can imagine, so a little deviation on the way may change the direction of their sailing, in short, even if they turn their spacecraft one hundred and eighty degrees, and move forward in the direction they came from, it is quite difficult to return to the original starting position, enough space, and magnify their slightest mistake to the extreme.

At this time, Liu Xuan's navigation beacon left at that time is to be put to use, two points to determine a line, even in space, this theorem is absolutely applicable, as long as the direction of the navigation beacon is determined, they can follow the straight line determined by the two points, determine the direction of progress, accurately determine the distance they sail, 100% guarantee to return to the original position.

From the time they sailed to the present, they had not used a buoy to determine how far they had traveled, and there were other devices on their Discovery to determine the distance they had traveled, which was the most accurate. After all, the two points determine the straight line, the buoy and the spacecraft determine the length of the vector, and their spacecraft follows a curve, which cannot be measured by connecting with the buoy. So the original function of the beacon is to guide them back to their original position.

Another important reason is actually because it is very connected to the buoy

The energy consumed, the radio waves that can be transmitted in the universe, also require a very strong energy supply, and their exploration is okay, in this place full of stones, there is almost infinite energy. However, the energy carried by the navigation beacon is not much, and it is impossible to connect with their ship at all times.

Seeing that no one finally objected, Liu Xuan gradually accelerated his adjustment speed, no matter what, turning the spaceship first was the first thing, and Liu Xuan did the same. The next step is to determine the direction of the buoy, so as to make a connection to determine the direction of his return.

But when he saw the data that came back, Liu Xuan's face instantly became ugly, even more ugly than the wrong face that he found out about the other three people just now. At the same time, on the console, the speed of the ten-finger operation was also accelerated, and in mid-air, a window was opened, but Liu Xuan's face was still rapidly becoming ugly.

Liu Xuan rarely had such an ugly expression, even when he discovered the mysterious planet civilization at that time, Liu Xuan's face was not so ugly, but now, Liu Xuan's face was almost ugly, even the three people who didn't pay attention to Liu Xuan's operation realized that something was wrong.

"What's going on, did we find something else?" Qin Ming is a person who understands Liu Xuan's face better, when he was fighting against the mysterious planet civilization, it was normal for Liu Xuan's face to be ugly, but his face was so ugly, even Qin Ming saw it for the first time, so he was one of the three people who couldn't help it, and asked Liu Xuan.

"It's gone. It's gone. The navigation beacon we set up at that time was gone, no matter what means were used to scan it, it was impossible to find it, and now I have used all the means that can be scanned to the navigation beacon, but I have not found the location of the navigation beacon, as if the navigation beacon has completely disappeared. Qin Ming's question finally broke Liu Xuan's last confidence, he sat down on his chair, staring blankly at the various windows suspended in mid-air, his means had been exhausted, and he still hadn't found it.

Liu Xuan's somewhat desperate words finally made the other two people realize the seriousness of the matter, they are a whole, even if their mood is very low just now, when something goes wrong, they will still face it together.

After all, Wang Meng has been professionally trained, and after hearing that something was wrong, he also stood up, pulled the operation interface opened by Liu Xuan just now in front of him, and at the same time used his own means to search, wanting to find a little clue, but what he did was just repeating Liu Xuan's operation, and still nothing was found, but the suspended window was doubled.

"What the hell is going on?" Wang Meng finally gave up, and like Liu Xuan, he sat down in his seat, his eyes were not dull just now, but a little frightened.

"Obviously, there is only one possibility in such a situation, and that is that there are indeed advanced civilizations, but we can't find where they are. That buoy, you also see in the company, even if there is no energy, even if it is powder

Broken bones can provide rough information about their own position, and the radiation emitted by that special radiation raw material can't allow us to calculate the distance we sail, but it is still possible to provide a rough location. Even if it is a very vague location, it is quite obvious in the universe. But now, there is nothing left, as if the beacon has completely disappeared, or it has been shattered into a molecular state. In either case, it requires the participation of a civilization. ”

Liu Xuan's words were quite heavy, but what he said was the truth, and now, the four of them didn't know whether to be happy or sad.
