Although Xuan Mu is not an expert in this area, he is not stupid, and naturally understands what Liu Xuan said, this is just a means of observation, and it is obvious and certain to see the objects that enter the solar system.

"But what if an asteroid from the outside world also passes through the Oort Nebula, we shouldn't be able to tell the difference, right?" Xuan Mu also put forward his own views.

"Do you think that aliens have come to our solar system with only one space battleship?" Liu Xuan didn't answer directly, but asked Xuanmu instead.

Xuan Mu also understands that an asteroid can only bring up one track, and if a real alien enters the scope of the solar system, it will definitely bring a lot of tracks. Through this inference, it can be concluded whether the solar system has entered by other civilizations.

"All this is just speculation, to really make sure that we still need to launch a probe, according to the accuracy of the current probe, we need to launch a probe at least to reach the orbit of Neptune in order to better detect the changes in the Oort Nebula, these will take time, however, according to the current actions of the Federation, we still have a lot of time." Liu Xuan finally solved his breakfast and finally summed it up.

"In fact, the most important thing is that even if we are sure that there is a living form that has crossed the Oort Nebula and entered the solar system, we still don't know the civilization level of the other party, and whether we can defeat it. According to Mr. Shen last night, the Federation has spent the past ten years building the Earth Defense System, but there are not many starships for attack. Qin Ming also shook his head and sighed. It can be seen that he does not have high expectations for this incident.

"I started to design and improve the propulsion system to minimize the probe's close to Neptune's orbit, and at the current rate, it would take about seven years for the event to reach Neptune's orbit, and my improved design should be able to reduce that time by another two years, and five years should be about the same." Liu Xuan stood up and wanted to leave.

"Are you really sure you want to change our plans? You know, at the moment, our plans don't conflict with this matter. Qin Ming was actually struggling in his heart, they still had to spend an extra five years to determine the news of a guess, which was definitely more than worth the loss for him.

If they were just worried about the sky and didn't have the things they thought about, then the loss must be huge, and the five years of time were wasted. Even if they take 10,000 steps back, they have really explored this matter, what can they do? Since the Federation has blocked this news, it is useless for them to explore it, and the only use may be to confirm their inner guesses.

"We can't live without Earth!" Liu Xuan turned his head, his face was very serious, his two eyes stared at Qin Ming tightly, and then said in a low tone. After that, he took the elevator straight to the rocket launch site, where he would spend the next few months.

"Actually, I agree with Liu Xuan's opinion, we enter the wormhole not only for a reputation, but also to promote the development of human civilization, if even the earth is gone, there is no point for us to enter the wormhole, the current priority is to ensure the safety of the earth itself. To be honest, such a federal blockade of news is very unkind. Seeing that Qin Ming didn't understand Liu Xuan, Xuan Mu was also enlightened by the side.

"I understand what you say, but I just don't like the way the Federation does things, why do you want to block the news? It would be unfair to us to know that it would take us five years to get the secrets of the Federation. Especially for Liu Xuan, he is just a scientist, why do we attach so much importance to these, so to speak, even if we know this news, what can we scientists do? The Federation doesn't allow it, we can't do anything. Qin Ming wrapped his arms around him, buried his head in his chest, and said bitterly.

"We're just doing our part as an earthling. The Federation is the Federation, the Earth is the Earth, we can give up the Federation, but we can't give up the Earth. It's not for the Federation, it's just for the sake of the Earth, for the Land, for the sake of our homeland. A pinch of loess and a piece of blue sky are all worth protecting, aren't they? This is true for ordinary people, let alone us scientists! "Xuan Mu obviously understands the essence of things better than Qin Ming, they are no longer working for the Federation, but for the earth they love.

Qin Ming also understood, and didn't say anything, but immediately devoted himself directly to his own research in Xuanmu's helpless gaze.

Qin Ming understands the significance of his research, antimatter can not only be used to pass through wormholes, but also can be used as a new type of fuel, his research is very useful, what he needs to do is to make new breakthroughs.

On the other hand, Liu Xuan also went to the rocket launch site and directly called many rocket engineers and detector experts with a phone call to start discussing the new detection system.

Through the exchange, Liu Xuan gradually became excited, because he got a very important news, that is, the Transwarp company has a reserve of detectors, in other words, the most difficult part of the detector has been completed for the most part, as long as a certain modification is carried out, it can be directly loaded on the rocket.

It seems that these engineers have also been specially explained, and Liu Xuan's words must be implemented effectively. After Liu Xuan explained the goal of the transformation to the detector experts, he led many rocket propulsion experts to start building a new rocket thruster.

This time, Liu Xuan did not use his latest technology, after all, he was used for long-term manned flights, and it was not very useful for this unmanned probe. He wanted to use these only to be very in his own is to discover the propulsion system utility improvement. In other words, after consuming the same amount of nuclear fuel, it can travel a longer distance, and most importantly, the speed is further accelerated, which is the basis of what Liu Xuan said to Qin Ming just now to produce detection results in five years.

Originally, the original thruster experts of the Star Ring Company looked down on this new face very much, but when Liu Xuan's new type of drawings projected a three-dimensional image holographically in the air, they also understood Liu Xuan's strength, and immediately no one looked down on Liu Xuan, and they were obedient to Liu Xuan's requirements, which was the respect for the knowledgeable.

The four of them began to work like tea, and the hardest of them were Liu Xuan and Qin Ming. Their invention is not only used in the current era, but also plays an extremely important role in the future, in fact, fundamentally speaking, Qin Ming's research direction is in line with the future trend, that is, antimatter is used for spacecraft propulsion.

Liu Xuan discussed the construction with many engineers almost day and night, and new parts were continuously sent to the rocket launch site, they needed to do too many things, after all, time waits for no one. However, the good news is that the detector has been modified according to Liu Xuan's requirements, and the commissioning work has also ended, and the rest is to install and launch it. It is worth mentioning that this probe has a lot of castration functions, and it does focus on strengthening the strength of the radio telescope, in order to detect the trajectory changes of the Oort Nebula better, more carefully and faster.

As for the direction of observation, they also know, in fact, this is what the Federation told them. The direction of the last Kuiper probe should be the direction that the Federation wants to watch out for, and they only need to focus on that direction.

Correspondingly, Xuan Mu is relatively easy, his invention is actually difficult is the idea, this idea he put forward decades ago, and now his invention has been transformed by others is also very good, his main research direction is lighter, more efficient. Now there is no need to fly manned for a long time now, and his research speed does not need to be too fast.

As for Wang Meng, not to mention, his talent is still very strong, it took less than a month to master the piloting method of the new spacecraft, and now he has become a teacher, teaching the starring company's own astronauts.

Everyone is working hard for their goals.
