Above the earth, in low earth orbit, and at the Guardian space station, Liu Xuan and the three of them are leading a group of researchers to work hard, and there is less than an hour before the deadline, and all of them have not eaten or slept, and they have been working for a full twenty-three hours.

Liu Xuan was already tired and couldn't stand steadily, at this time he was lying on a chair, panting heavily, he hadn't stopped for twenty-three hours, just now he finally finished guiding the last step, and now he finally had time to rest.

There is still an hour to go, according to Liu Xuan's plan, the time is just right, Xuan Mu and Qin Ming are still working hard, Wang Meng also doesn't know where to run, after entering this place, the three of them just lost contact with Wang Meng.

Time passed little by little, and finally, with three minutes left before the twenty-four hours, they had finally completed everything, including the final inspection part.

When Liu Xuan and the three of them returned to the room assigned to them, they directly lay on the bed and fell asleep, fortunately, Wang Meng was still in this room, so he became a temporary nanny for the three of them, adjusted the sleeping position of the three people, and then put the special food in the space next to them, and then he also fell asleep.

Almost four hours later, the notice came, informing all the scientists to go to the command room, Liu Xuan and the four of them also hurriedly got up, ate a few mouthfuls of food, and hurriedly walked towards the command room.

When they arrived at the command room, there were already a lot of people arriving, after all, they had "eaten".

"Hello experts, I am the supreme commander of the Guardian, Ringer, with the efforts of Liu Xuan's team, the interstellar missile has been installed, and it will be launched in five minutes." Commander Ringer appeared at the top for the first time and said to them condescendingly.

At this time, Ringer would not invite Liu Xuan to the highest command platform alone, they were all on the first layer, that is, the lowest layer, along with a group of scientists.

Everyone's faces also revealed joy, and they all threw expressions of admiration at Liu Xuan and the four of them, and the efforts of Liu Xuan and the four of them were also recognized by many scientists.

Five minutes quickly, in front of many scientists, Ringer pressed the launch button, and after the entire Guardian trembled slightly, a missile dragged a dark blue tail flame and flew towards the deep space, carrying the hopes of these people, running towards the dark deep space.

Many scientists still did not leave, and after Ringer's application and the consent of the Federation, Liu Xuan and the four of them were allowed to return to Earth to help the Star Ring Company in the research and development of stellar-class warships. The four of them were also given permission to return to the Guardian at any time. Even the four of them were specially allowed to enter the lunar base.

Liu Xuan listened to his partner's advice and decided to return to Earth first, and wait until he had time to enter the moon base. The most important thing now is to increase the combat power of the planet.

Liu Xuan and the three of them were ready to set off immediately, and Zhang Tianze was still in charge of flying the aircraft, and they would have to rely on their own flying machines the next time they came. Of course, Transwarp still has its own flying machine.

"Professor Liu, the commander asked me to inform you that if there is any news that can come directly to the Guardian, we have already given you the permission to open the hatch, of course, you can only come in a specific aircraft every time, and we will receive the signal if you put this thing on your aircraft. It's worth noting that this thing can only be tied to a flying machine. After Zhang Tianxue emphasized, he came to the cab.

The four men understood, then boarded the craft and flew directly towards Earth.

After a short time, the four of them returned to their own research room, although it was only a few days, but everyone was very tired, and when they returned to their rooms, they just went to sleep upside down, and they would talk about these things later.

When they woke up, it was already night, Wang Meng had already cooked the meal, Wang Meng was not in vain this time, when the three of them worked hard to transform, he went to learn the piloting of this flying machine by himself, fortunately, Zhang Tianxue had nothing else to do at that time, and taught him personally.

Wang Meng's talent itself is very high, plus he has studied before, this time it is just a real attempt. Compared with Liu Xuan, he is the most relaxed and there is nothing wrong with him.

"What should we do next, we won't just wait stupidly for the result." Qin Ming asked Liu Xuan while stuffing food into his mouth.

"We needed to control the detector remotely, and luckily I had a camera on it last time." Liu Xuan tried hard to swallow the food in his mouth, and then said to the three of them.

"Probe? That Neptune probe? Is it any use? Qin Ming was also stunned, he was about to forget that they also had a Neptune probe, according to the time estimate, the current probe should have entered the orbit of Neptune and started to operate normally.

"Have you forgotten what I said? The final collision is to take place near Uranus and Neptune. Got it? Liu Xuan smiled mysteriously and reminded them.

"Can we see the moment of collision directly?" Wang Meng was taken aback, and then blurted out directly.

"Well, it is estimated that the time it will take us and the Federation to receive the news should be about the same, but because we are on Earth and the Guardian is in space, it will be a few seconds apart." Liu Xuan had already finished eating his own food, wiped his mouth and said.

"So what are you waiting for? Pan him! Qin Ming was also very excited, originally he thought that this matter still needed to be notified, but he didn't expect that they already had the means to watch it directly, which was undoubtedly good news for them, they could prepare in advance, so as not to be too passive.

At this time, it was already late at night, but the four of them had completely reversed their biological clocks, and without saying a word, they began to adjust, of course, with Liu Xuan as the main personnel, they were just Liu Xuan's assistants.

It doesn't take much work, just calculate the location of the collision and aim the detector's lens at that place in advance. For the four of them, calculating the place of collision is the most difficult, and they did not get the results of the calculations of the Guardian scientists, so they had to start the calculation again.

However, they have time, ten days, to calculate, it is not a very difficult thing for them.
