"Yes, there is a star that moves in an instant, and this is it." Liu Xuan pointed to the stars in a place, indeed, after adding the grid lines, they could clearly see the difference between the two videos, a star that should have not changed was actually moving, which made them very shocked, they couldn't imagine what kind of technology could make the planet tens of thousands of light years away suddenly move.

"Could it be that the technology of this alien civilization can already blind our perception and cause problems for all our probes?" One parliamentarian also put forward his own point of view.

Liu Xuan did not ask any questions about the councilor's point of view, but continued to say to himself: "I have already studied the star, it is a star five thousand light years away, after research, I have not found any recent changes in this star, which means that the star itself has not changed, and we have changed." ”

"So you mean that this civilization does have a level of science and technology that is much higher than ours?" It was also at this time that the Speaker of the Parliament raised his own questions, which was a difficult outcome to accept.

"I can't say that, because his thruster type and speed are already at the level of civilization, basically the same as us, in other words, we may have been blinded by our own detectors. Please note that I can guarantee here that our Transwarp exploration satellites are not damaged in any way, I wonder if you have seen the story of the Stealth Cloak? ”

Liu Xuan didn't plan to announce his discovery from the beginning, he wanted to guide these people to discover the means of this alien civilization little by little. Liu Xuan also has his own ideas, after all, he can't serve the Federation for a lifetime, what he has to do is to pass on his manual observation method regardless of hard work.

"What do you mean?" A councilor seemed to have remembered something, and his eyes burst with brilliance, and the gaze that looked at Liu Xuan changed instantly, this was a look of worship.

"Say what you think, you shouldn't be wrong." Liu Xuan also smiled slightly when he saw such a performance, it seems that his guidance has already had an effect, and this person is obviously aware of what he means.

"You mean to say that the alien fleet used a strange stealth method to evade detection by all of our probes, and they used the same stealth cloak method from our original story to treat this camera."

"Yes, then please explain this phenomenon to everyone." Liu Xuan bowed slightly, indicating that what this person thought was correct.

With Liu Xuan's confirmation, this councilor also had confidence and began to explain.

"The stealth cloak, the principle of this thing is actually very simple, that is, the part of the cloak is covered by the collection of information, and then perfectly restored to the front of the cloak, so it seems that there is nothing in this place, but the back of the cloak is indeed Tibetan, this is the stealth cloak. But this thing also has certain drawbacks, the key is that in his edge part, even if the image in the middle of the cloak is offset, it is not easy to find, but a comparison between the edge position and the surrounding environment may find that this scene is actually fake. ”

"For example, if the invisibility cloak simulates a table, and the person hides under the table, and the invisibility cloak is placed on top of the table, the invisibility cloak can completely hide the person hiding under the table. However, when the edge of the cloak is compared to the table, it is likely that the side of the table, which was originally a straight line, has broken in the middle. ”

"In fact, with the development of science and technology, the invisibility cloak can also simulate 100% of the things it covers, but once it moves, it is easy to leak the invisibility cloak."

What this councillor said is actually a little vague, but everyone understands a little bit, in other words, this thing is like having camouflage on the surface, integrating itself into its surroundings, so as to achieve the role of stealth, which actually has the same principle as chameleons.

The only disadvantage of this thing is that if the movement speed is very fast, the color change of itself is too late, and it is easy to teleport the object. It's like the sudden change of stars in this video.

"You mean, in fact, they have already arrived in our solar system with stealth technology, but they have deceived all our probes, and we have not found out?" The Chief's trembling voice sounded, and then he also noticed the discord in his voice, and coughed to hide his embarrassment a little.

"Yes, that's why I said last time why I didn't need to be in a hurry, they had actually arrived in the solar system a long time ago, but I guess they also wanted to know themselves and their opponents, and win all battles, so they didn't attack at the first time, they have actually been lurking, like a poisonous snake, waiting for a certain moment to come, and catch us off guard." Liu Xuan exhaled deeply and said his final judgment.

"Have all our preparations, all our armaments been clearly detected?" The council chief was a little distracted, lowered his head, and muttered to himself.

What does this mean, this means that Liu Xuan's remarks have completely proved that the efforts of human beings in the past eight years have become useless! All their enemies know how to fight this war?

It was already completely quiet in the conference room, which was originally very noisy, and everyone was silently contemplating, they didn't know, they didn't know what to do next?

"Is it too late for us to move all sorts of defensive weapons?" A councillor muttered to himself that most of their defensive weapons were deployed near Neptune, in order to completely stop the alien fleet near Neptune, but they miscalculated, compared to the defense near Neptune, the defense of the earth is still a little lacking. Because they thought at the beginning that the Earth's defenses still had time to continue to build, but they had completely miscalculated.

"You've got the answer." Another parliamentarian who looked like he was a senior member said.

Yes, in fact, they all have the answer, if everything Liu Xuan said is correct, if they move the defense system and transfer back the defense system that was supposed to be against the outside, the alien civilization will also know that they have discovered their whereabouts, and it is estimated that they will attack at the first time.

At this time, if the human civilization still does not show that it has discovered anything unusual, then the human civilization actually still has more time to prepare, but once the defense is mobilized first, they will not have any time to prepare.

"Of course, everything just now is speculation, and our conclusions are actually based on this video." Liu Xuan looked at everyone's decadent appearance and added.

"Professor Liu, we all know your personality well, if you are not more than 50% sure, you should not bring it up, right?" The chairman of the council obviously knew Liu Xuan, and he didn't have much doubt about his words.

"I just want to know, Professor Liu, do you have a way to guess where they are after entering the solar system?" The Speaker then asked. Since they can't act rashly now, they also have to find out the enemy's position before they can move on to the next step.

"I have a solution, and this method can further prove whether my conjecture is correct or not." Liu Xuan nodded and said affirmatively.

When the council leader heard that Liu Xuan still had a way, he immediately breathed a sigh of relief and continued to ask: "What is the method, and do we need to do something?" ”

"I need all the satellite video for the past three days, or do I just borrow the strongest supercomputer from the Federation." Liu Xuan said his request.

"These are all no problems, we would like to know more about your methods?" The head of the council nodded, indicating that Liu Xuan's requirements could be met.

"Well, you've seen it too. When this starship moves, the stealth system also changes its color at all times, and maintains assimilation with the surrounding environment all the time, which makes it impossible for our eyes to observe, but in front of the detector's camera, in fact, changes can still be detected with a certain accuracy, and these changes are the changes in image pixels! The color of the pixel is very right, and the camera can also distinguish subtle color changes that the human eye cannot distinguish, just like everyone looks at the color number of lipstick, some lipsticks look basically the same color, but when it is turned into three primary color data, there is still a big difference. My idea is to use a supercomputer to analyze these images, and if there is a change in pixels, it means that the alien warship has passed here, and we can plot the trajectory of the alien fleet after reaching the earth little by little. It's just that the amount of information in these videos is so large that it can only be calculated by the most advanced quantum supercomputers available today. ”

Liu Xuan said very carefully, and it was also very simple and easy to understand, and they also understood that Liu Xuan's method was very feasible.

The speaker of the parliament immediately made a decision, saying that the federal parliament would cooperate with Liu Xuan's work.

"Besides, those defenses are better off not moving now, we actually have some use, albeit at a high cost." Liu Xuan finally reminded many parliamentarians.

"Huh? Professor Liu, what do you mean that there are other uses for these external defense systems? What is it used for? A councillor who was obviously in charge of defense couldn't help but ask, in his opinion, the defense system that could not be transferred back could actually be discarded.

"Bait!" Liu Xuan smiled slightly and said to this councilor.
