Ringer also knew early that they were going to come to this place, and when they came out of the flying machine, Ringer was already waiting for them outside the flying machine, which flattered Liu Xuan and the four of them, and Liu Xuan also hurriedly stepped forward and stretched out his right hand.

Ringer shook Liu Xuan's hand with a smile, and then said to him: "Professor Liu, we know the purpose of your visit this time, and we have also received the order of the Federation, and now I have summoned all the researchers to the laboratory, just waiting for your order." Now it's all about you. ”

"Commander Ringer is polite, our primary purpose now is to conduct an experiment, and I don't know if my inference is correct for the time being. All of them can be ordered to do their own thing, and when my research succeeds, it will be manufactured on a large scale. ”

Ringer didn't say anything, nodded, the duty of a soldier was vividly displayed in his body, since it was already an order from the Federation, what he had to do was to try to meet all of Liu Xuan's requirements.

Liu Xuan was brought to the experimental site by someone, he just asked for a few researchers, as he said, he needed a prop for the experiment. Commander Ringer also came over, and he wanted to see what Liu Xuan was doing. Obviously, even the Federation cannot trust Liu Xuan 100%.

Liu Xuan also knew this, so he didn't ask any questions when he saw that Lin Ge also came over. Liu Xuan found a floating screen, connected his bracelet, and began to tell his conjecture.

"Next, you will see another video, which is also the scene of the collision between our interstellar missile and Starfall, but from a different angle, please see what is worth noting." After Liu Xuan finished speaking, he directly clicked on the screen to start playing.

The picture began to change, this is the picture that Liu Xuan and the four of them watched at that time, that is, the picture of the collision of the starfall and the interstellar missile taken from the perspective of Neptune.

Just glanced at it, Ringer was full of shock, he didn't know that there was such a video in Liu Xuan's hands. But he was just shocked, this matter is not a violation of federal law, and he can't say anything, but he has some doubts about the source of this video.

Soon, the video was over, and the final result was completely consistent with the public video of the Federation, just like Liu Xuan said, this is just a different angle.

"This video was accidentally captured by the Neptune probe of Star Ring, but compared to the video of the Federation, there is an obvious breakthrough here." Liu Xuan first introduced the source of this video, so that they should not doubt the authenticity of this video.

But Ringer is not stupid, what does it mean to "shoot unintentionally"? This angle, coupled with the clarity, is deliberately shot at first glance. However, he also confirmed the authenticity of this video, and he also knew that the Star Ring Company had a Neptune probe.

"Everyone, please look at a picture carefully, this is Starfall's tail thruster, in fact, it is not much different from our thruster, except that its thruster uses special fuel, so that it can run at high speed for a long time. But what caught my eye the most was the pothole, and if you look closely, you can even see the structure inside. Liu Xuan stopped the image in one frame and pointed to the place that seemed to be corroded.

Many of the researchers also craned their necks and looked closely, and they could clearly see the corroded depression.

"We also know that there are some failures in the tail propulsion system of this starfall, which is presumed to have been caused by hitting an asteroid in the Kuiper Belt, and we can boldly assume that the place where the asteroid hit is this position, and it is also because of this failure that the thruster was severely damaged, reducing to a speed of one astronomical unit a day." Liu Xuan continued to say reasonably, and many researchers nodded in agreement.

"But we can all imagine that if it hits this place, it can't be corrosive, it should be just a simple depression." Liu Xuan continued to say his conjecture.

"Then we can make a bold assumption that there is nothing special about the external material of this starfall, after all, we don't know about extraterrestrial metals, and now we can only make bold assumptions."

"So in the end, I came to the conclusion that the shell of this starfall did not react with the asteroid rocks to cause this to happen." Liu Xuan explained his assumptions in one breath.

"Professor Liu, what element asteroid are you referring to? There are many kinds of asteroids. One of the researchers also asked questions.

"I don't know, I can only rely on probability. The largest number of asteroid species in the Kuiper Belt are mainly iron-nickel, and we can directly assume that this shell has a chemical reaction with the iron-nickel asteroid. Liu Xuan could only guess that this matter was a matter of luck from the beginning.

All the researchers were silent, they knew that there was nothing wrong with Liu Xuan's guess, and ordinary people would speculate like this when they saw this matter, but speculation is speculation, and it still needs to be verified in reality.

"Now there are thirty days before Starfall arrives on Earth, and the last ten days are reserved for antimatter weapons, if we get closer to Earth, the use of antimatter weapons will bring great harm to the Earth, that is, we only have twenty days to conduct an experiment, and if it is successful, the next time is the last strike time left for us. But no matter what, we can't take up the last 10 days, this is our last guarantee. Liu Xuan said to them in a deep voice.

"Also, Commander Ringer, I need a couple of meteorite samples from Earth, and this is our missile head." Liu Xuan's voice changed, looked at Ringer who was pondering on the side, and said to him.

"I understand, I'll explain it directly to the Federation, and I'll deliver it this afternoon at the latest." Ringer smiled and nodded, and walked out of the lab.

Seeing Ringer's reaction, Liu Xuan also smiled slightly, he knew that his conjecture just now had completely moved Ringer, and Ringer was also relieved to hand over this matter to Liu Xuan to do.

After seeing Ringer out, Liu Xuan turned his gaze to the researchers.

"Do you have any other questions?"

"Professor Liu, isn't twenty days too short?" One researcher is also a little unconfident in terms of time.

"You don't have to worry about the thrusters, we can use the latest thrusters of the Transwarp Company directly. It will take us less than a day to turn a real meteorite into the head of a missile, and it is worth noting that the meteorite used this time must be not small, so that we can observe the final result more carefully. ”

Many researchers nodded, if the thruster problem was solved, then an experiment would be completed in a few days.

"But even if our experiment is successful, we will need more meteorites to destroy this starfall. It's hard to calculate the exact amount, and we only have one chance. Another researcher also pointed out the shortcomings of this operation.

"The more meteorites we can have, the better." Liu Xuan said mysteriously.

Many researchers have gathered their eyes, they don't understand, what is bigger, the better, first of all, not to mention whether there are enough meteorites on the earth, even if there are, the transportation of large meteorites to the sky is also very energy-intensive, and the speed will not be very fast, so that the last ten days are difficult to guarantee.

"We don't need meteorites, we have asteroid belts." Liu Xuan smiled slightly.

Just one sentence, so that all the researchers understood, they all died into a misunderstanding, that is, meteorites need to be transported to the sky, but they forgot that there is an asteroid belt between Jupiter and Mars, and the asteroids in it are enough for them. Once the experiment is successful, they can directly select a giant asteroid, install thrusters, and run directly in front of Starfall to stop it.

At this time, all the researchers looked at Liu Xuan with admiration, Liu Xuan's idea was indeed different, but it was very feasible. It's just that a few thrusters need to be specially modified.

"Do you have any other questions?" Liu Xuan asked for the last time.

This time, everyone shook their heads, there was no technical problem in the implementation of this plan, and the most critical question was whether Liu Xuan's conjecture was right or not. This is currently the most critical problem in stopping this starfall.

Liu Xuan announced the adjournment of the meeting, and everyone began to prepare for the upcoming experiment.

At first, Liu Xuan also planned to directly use a huge asteroid to block the starfall, but after careful calculation, he found that the feasibility was not high. If the shell of the starfall does not react chemically with the asteroid, there is no problem in breaking through the asteroid at the speed of the starfall. The only possible gain would be a further reduction in Starfall's movement speed, but that didn't mean much to them.

Therefore, it is at this time that it is very important for the starfall's special shell to react with the asteroid. Once this conclusion is confirmed, it is only a matter of time before the starfall is stopped.

In fact, Liu Xuan probably guessed that the most direct purpose of Starfall, an alien interstellar missile, may be to find rocks on the earth and then react with them and burst out with more powerful destructive power. Otherwise, with the size and mass of the starfall, it is difficult to cause any substantial damage to the earth.

Liu Xuan's four people were also involved in manufacturing, and at this time, they had already brought the propeller of the Star Ring Company, and the transformation could already begin.
