This time the deep sleep gave Liu Xuan a completely different feeling, no longer as relaxed as the first time, but felt a huge pressure, Liu Xuan This is the second hibernation, but also has experience, he also knows that there will be no feeling when the real hibernation is made, let alone any dreams, this situation will only appear when he is awakened.

Liu Xuan struggled to open his eyes, and a person appeared in front of him, this person was very familiar to him. Liu Xuan now has to sigh, sure enough, his inventor knows his invention very well, and Xuanmu is the first to wake up, what appeared in front of him is not Xuanmu.

Struggling to sit up, looking around, it was no different from when he hibernated, and in the other two hibernation warehouses, Wang Meng and Qin Ming had just woken up.

"How many years have passed?" Liu Xuan rubbed his temples, trying to make himself sober as much as possible, and then asked Xuanmu in front of him.

"It's been three years, and this time we've been hibernating for three years." Unlike other people, Xuan Mu's expression was a little serious, which was really noticeable for Xuan Mu, who usually behaved very indifferently.

"What's wrong? Did the probe enter Neptune's orbit? Is there a message coming in? Liu Xuan slowly came out of the hibernation warehouse, gradually adapted to his body, and patted his head from time to time to make himself more sober. However, Liu Xuan obviously felt that the effect of the medicine he took before hibernation was too strong, and Liu Xuan, who was awakened in advance, couldn't wake up, unlike the spirit of Xuanmu at this time.

"Well, the news has already arrived. However, at this time, the probe still did not reach the orbit of Neptune, and it was still on its way, but in the process of flight, the probe had already scanned what we needed, and the data had just been sent and I was awakened, and the data was being converted into an image format by a high-performance computer. However, there are some things that you should know better than I do. Xuan Mu's face was still very serious.

Although Liu Xuan was not very sober at this time, he also understood the meaning of Xuanmu, what does it mean to have not reached the orbit of Neptune is to detect something, which means that the changes in the Oort Nebula are too great, even if it is far away near Uranus, it has been observed, Liu Xuan's heart thumped violently, and the bad premonition became more and more obvious. At this time, the unclear mind also became much clearer in an instant.

For them, the final moment of judgment has come. What happened beyond the Oort Nebula, they soon knew.

Two light-years away, what happened to them, their feelings were still very complicated. For the entire history of human civilization, challenges and opportunities are accompanied by the development of human civilization as a whole. They also don't know whether this time is an opportunity or a challenge. But in any case, they also understand that the newborn child of the earth is finally known to the entire galactic society. Their generation will have one of the most intimate encounters with extraterrestrial life.

"Dididi!" Just when Liu Xuan and the others were in a very complicated mood, the computer in the laboratory rang, and they all understood that the final news was coming.

Liu Xuan trembled his hands, swiped slightly in the air, and gave an order. At the same time, a black-and-white image appeared in mid-air, very blurry, but it was basically enough for Liu Xuan. Just glanced at it, Liu Xuan staggered back dozens of steps, he saw it, saw what he guessed, and there was more than one.

Seeing Liu Xuan's appearance, the other three people also had their own conjectures to some extent, it seems that a few years ago, Liu Xuan's conjecture was correct, but it didn't behave like this.

Xuan Mu also hurriedly crossed Liu Xuan and looked at the black and white picture. The picture was as simple as a child's drawing, almost a jumble of dots. However, there are also a lot of sparse places in the interior of these dense and cluttered points, and there are quite a few of them. The sparse points and the surrounding dense points formed an obvious dividing line, and those black spots were sparse like an eye, staring closely at the four people in front of him, Xuan Mu's face turned white instantly, and he sighed heavily. Although he is not very proficient in these things, he has dabbled in them, and now that he looks at them, he can also see some clues.

Seeing the reaction of the two of them, Wang Meng finally couldn't help it, and asked blankly, "What happened?" What do you see on this diagram? ”

"See these sparse spots? These are all tracks, that is, there have been so many spaceships crossing here, you know, you think that our technological level is still not up to the Oort Nebula. In other words, we were also wrong in our estimation back then, and the solar system almost had an alien fleet! Liu Xuan explained carefully to Wang Meng.

"No, it seems that there is something wrong." Qin Ming had been looking at this picture carefully just now, and after hearing Liu Xuan's explanation, he also put forward his own opinions. Liu Xuan and Xuan Mu moved their eyes to Qin Ming almost instantly, wanting to hear his different opinions.

Qin Ming took a step forward, pointed to the image in mid-air and said, "These tracks still look very clean, that is to say, the other nebula gases have not completely filled the past.......

"What do you mean!" Liu Xuan didn't wait for Qin Ming to finish speaking, he just walked forward quickly, carefully examining this image, indeed, Qin Ming's conjecture was very correct, these tracks were all new and not at all like they just appeared ten years ago, in other words, outside the Oort Nebula, there were new objects that had just entered the scope of the solar system.

"In addition, you are looking at this place, the immortal has a relatively faint track!" Qin Ming pointed to the lower right corner of this image, where Liu Xuan hadn't noticed it seriously.

Just after a glance, Liu Xuan was sure that there was indeed a track here, and this track was already very faint, and the nebula gas had almost completely filled this place.

"Where it was detected ten years ago by the Federation!" Liu Xuan took a breath of cool air, but he didn't expect that this time the enemy would be divided into two groups to enter the solar system.

"There is only one track here, which means that only one thing entered here ten years ago, we can boldly guess that this is the other party's detector, as for whether the other party is friend or foe, we don't dare to draw conclusions early." Qin Ming is still very calm, and he is also the head of the way when he analyzes it.

"Let's start with this track below, and guess the possible destination of this thing!" Liu Xuan gave the analysis instructions to the supercomputer.

A three-dimensional map of the solar system appeared in mid-air, and the red extension line began to appear, and as the supercomputer calculations began to extend, it finally settled on a point, which was a planet, exactly one astronomical unit from the sun, and its name was Earth.

The four of them were completely stunned after seeing the result, what does this mean, coming directly to the earth?

"Take the remaining tracks as a whole and analyze their final destination!" Liu Xuan continued to give orders.

A green extension line appeared, extending in the direction of the sun, and finally froze on an orbit, which was calculated by the supercomputer. There is also a celestial body in this orbit, which is a satellite, and its name is the Moon.

Liu Xuan took a deep breath, his brain was already blank, and this simple calculation could clearly show that this civilization outside the solar system was coming for them! Moreover, they are also very aware of the situation around the Earth, and they also know that there is a satellite that can be their temporary base.

Liu Xuan still has some things he doesn't understand. Based on their tracks, we can roughly judge the speed of their engines, and from this, we can roughly calculate the degree of development of their civilization, Liu Xuanke probably knows that this civilization is slightly higher than the earth civilization, how can it detect such a small planet as the moon?

Of course, at present, these doubts are no longer important, no matter what means they have, anyway, they have already discovered the civilization of the earth. The solitary development of the earth is a thing of the past.
