Now there are still three hours left before the time given by Ringer, Liu Xuan has not much time left, if he really talks about it, his remaining time is less than two hours, after all, the place of departure is in the earth fortress, and Liu Xuan also has to rush to the earth fortress before the specified time.

"We don't have much time, this matter can't be solved, and there is no way to talk about other things, the thrusters used for our experiments should have been destroyed, this thing is like other fixed-orbit satellite probes, once it loses our control, it is still in the interior of the asteroid belt, I can't think of other results." Liu Xuan also smiled bitterly and said to them. In order to save time, the propulsion system used in the experiment was not installed at all, which is also an important basis for Liu Xuan to assert the consequences of their thrusters.

The three of them were silent, they also knew that Liu Xuan should not deceive them, and after knowing the three of them for so long, Liu Xuan really didn't deceive them, which is why the three of them trusted Liu Xuan so much.

But after all, time waits for no one, there is no time to discuss their plans, they also need to arrive at the earth fortress as soon as possible to wait for the Federation's dispatch, Fang Beihai is estimated to be already waiting for their arrival, this is not a small matter, Fang Beihai personally came forward is still very necessary.

What Liu Xuan needs to do now is to find a partner, although this journey is still very dangerous, but Liu Xuan also hopes that his partner is a person he is familiar with, not a new person, and this kind of thing does not appear at the beginning, so the candidate for this partner must appear among the three of them.

"Since it's already come to this point, then let me be the last candidate." Just when Liu Xuan was thinking about how to tell them about the situation, Qin Ming suddenly said that this was the so-called tacit understanding.

When talking about this incident just now, Liu Xuan also raised this question, although he didn't deliberately emphasize anything, but Qin Ming noticed it, this is the tacit understanding that Liu Xuan thought. Qin Ming was indeed very suitable to go with him. Among the four of them, only Liu Xuan and Qin Ming have space knowledge.

At this time, Wang Meng and Xuan Mu also understood that the most suitable of the three of them was Qin Ming, the two of them belonged to other fields, if they went with Liu Xuan, they would not be able to help Liu Xuan at all, and they might even cause unnecessary trouble to Liu Xuan, which was a bit more than worth the loss.

They all understand that they have a few catties and taels, and the relationship between the four of them does not need to show loyalty, and the most important thing now is to ensure their ability to return safely, neither of them can do this, in their eyes, Qin Ming is indeed the most suitable candidate.

"Well, we'll be back safe!" Liu Xuan also faced Qin Ming and said, now it is hypocritical to shirk or something, since all the people can see that Qin Ming is the most suitable candidate, Qin Ming can't fail to see it, in order to ensure the success rate of this operation, the two of them must work together.

Now that the candidate has been decided, all that remains is to act with the Federation, at this time it has begun to rain outside, which is a symbol of autumn, and the coming of autumn rain also means that the weather will become colder and colder, and in this season, Liu Xuan and his companions are about to embark on another completely different journey.

After discussing, each of them sorted out their own things, Liu Xuan had already applied to the Federal Assembly, and the Federal Assembly also agreed that the four of them could go to the Earth Fortress to prepare. There are still two hours left until the actual departure time.

Even if Liu Xuan is a lonely person, there is nothing worth bringing, two photos can be said to be the only things he attaches importance to, but these two things are the things he carries with him, they have always been stored by him, just in a special mezzanine of the clothes, usually, Liu Xuan basically lifted his shirt, that is, you can see these two things, in his opinion, this is all his property.

The first photo is a photo of him and his father and mother a hundred years ago, Liu Xuan at that time was really just a child, smiling very happily, Liu Xuan at that time didn't have so many worries now.

The second is his own family, Li Ping and his one-year-old child, Liu Xuan at that time was like a walking corpse, just thinking about how to make money to support the family, but also completely gave up the idea of his own research, Liu Xuan at that time was affected by his own family, and he was already focusing his attention on other places.

However, Liu Xuan at that time was the happiest moment in his life, and the warmth of his family also made Liu Xuan deeply feel the beauty of life, it can be said that it was Liu Xuan's happiest moment, and it was also Liu Xuan's most negative moment, he basically forgot to conduct his own research.

And for an hour and a half, the three of them walked towards the flying machine, this time, it was piloted by Wang Meng himself, and Xuan Mu also followed them on the flying machine, they had already discussed with the Federation, even if Xuan Mu and Wang Meng did not participate in this event, but it was also specially approved to wait for their return in the fortress.

Wang Meng's piloting talent has not been affected by his age at all, in manual mode, the aircraft piloted by Wang Meng can also be compared with those ace pilots, Wang Meng's ability has always been very strong, but he has never had the opportunity to show himself, this time the aircraft is his own opportunity, proving that he has the ability to pilot the new spaceship jointly built by Qin Ming and Liu Xuan.

During the whole process, Xuan Mu did not speak, and Liu Xuan was also difficult to speak, unlike the original heated discussion, this time, all of them fell into this strange silence. No one tried to break it, and no one even had the idea of breaking it, and in this atmosphere of silence, they were already close to the fortress of the earth.

"I've already started researching the combination of deep-sea technology and hibernation technology, and if I really talk about it, it's not very difficult to achieve, so as long as you come back safely, we have a good chance of implementing our plan thoroughly." Just when Wang Meng applied for landing, Xuan Mu finally couldn't help it, broke the silence on the spaceship, and said affirmatively to Liu Xuan and Qin Ming.

His meaning is already very clear, the skills needed now are almost all available, but as travelers, they still don't have their own time. Liu Xuan already had the experience of building the first thruster, and it would not take long to re-establish a new propulsion system for testing. Now they are really "everything ready, only the east wind is owed".

Qin Ming and Liu Xuan didn't say anything, but nodded solemnly at Xuanmu, they understood that this was Xuanmu telling them in disguise: You must come back safely, between us and our dreams, only you can return safely.

Wang Meng's application was approved at the first time, and a huge hatch of the Earth Fortress was also opened, and Wang Meng skillfully piloted the aircraft to fly towards the interior of the Earth Fortress.

At this time, it shows the importance of a real person piloting, leaving the protection of the earth's atmosphere, their aircraft are also the same as those detection satellites, losing the ability to automatic, and can only be piloted manually, Wang Meng's skillful operation at this time can also see how much effort he has put into this aspect, you know, the last time the starfall event came to the earth fortress, Wang Meng still didn't know anything about this thing.

The aircraft also stopped safely, opened the hatch, and all the personnel of the Earth Fortress were waiting for them, including Fang Beihai, the commander-in-chief of the Earth Fortress, Liu Xuan had already seen him at the meeting, although it was only a holographic projection, but he still recognized Fang Beihai for the first time.

"Hello Commander-in-Chief, you should have been notified by the Federal Assembly of the content of this operation, so I won't say anything else, is the flying shuttle ready?" Liu Xuan was the kind of person who went straight to the point, and when he saw Fang Beihai, he directly explained his problem.

"Hello, Professor Liu, welcome to the Earth Fortress with your partner, the test work of the flying shuttle is already at the end, but I still want to remind you that this thing is still in the testing stage, and if it weren't for the rush, the Federal Assembly would not have used this thing." Fang Beihai also explained the situation this time.

Now there were still twenty minutes before the final departure time, and after Liu Xuan and Fang Beihai exchanged a few words again, they also followed Fang Beihai towards the command room of the Earth Fortress. Along the way, they met many people who were busy, and as mentioned earlier, the equipment that operated automatically had completely failed, and many things still needed to be manually operated, which was why there were many people in the huge earth fortress who were active.

After a simple exchange and learning of the flying shuttle, the time has come, because the flying shuttle itself is a secret of the Federation, so Wang Meng and Xuan Mu were rejected by the Federal Assembly to see off the idea, at this time, it can only be Liu Xuan and Qin Ming two people walking alone to the inside of the flying shuttle, flying alone, facing deep space, facing the sun.

The interior of the shuttle is like the introduction of the Federal Assembly, in fact, it is not very different from the interior of a normal flying car, this is a beta version, and it must be as simple as possible.

"Flying shuttle, launch!" A muffled electronic voice remembered that the shuttle they were riding on had been thrown out of the Earth fortress like discarded garbage, and the two of them began to drive away in the direction of the sun.
