A new image began to appear on the screen. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

In the new picture, everyone saw the entire space city building complex not far away, and at the same time as the picture appeared, Atlas explained, "From the previous attack on the fleet from the space city to the present, people have observed that there are still a lot of things happening in this space city. ”

"Oh? What happened? Zhou Xin asked curiously, "You actually still observe that space city?" ”

"Just look at it when you're bored." The little girl replied, and then she began to tell what happened in the space city, "At first, people first saw the escaped spaceships return to the space city, and then the space city was quiet for two days, and during this time, no one noticed anything, and it looked as if there was no one in the whole space city. But—" After a pause, Atlas continued, "two days later, the whole space city was bustling again, and people saw that from almost every building in the space city there were ships flying out of the space, but the number of ships was not very large, and the total number of ships did not exceed a hundred, which was much less than the fleet that had been destroyed before. When they first saw these ships appear, they thought they wanted to organize and return to the planet. But then, the less than 100 ships gathered a little and docked in the largest buildings in Space City. As he spoke, Atlas focused the probe's camera on several buildings in the center of Space City, "These are the buildings." Over the next few days, more than a dozen ships flew out of other buildings, and these ships were later docked in those buildings as well. Then, on the screen next to her, she showed the image she had recorded earlier.

In the video, the entire space city seemed to be very quiet at first, and there was no movement at all, but suddenly, as if it had received some order, some spaceships began to fly out of the outer buildings one after another, and these spaceships did not make any stops after appearing, and flew straight to the center of the space city.

Staring at the picture on the screen, Zhou Xin felt a little puzzled, "Is there anything special about these buildings?" Why are so many ships concentrated. ”

The little girl shook her head, "Aside from the fact that they look a little larger than the other outer buildings, they don't see any other differences, maybe something will be discovered after the probe investigates." ”

"Well, what about next? What happened again? Zhou Xin nodded, and then continued to ask.

"There's nothing else going on from there." Atlas replied, "But in the past two days, we can still see one or two ships from the outer buildings continuing to concentrate on those buildings, so people are a little curious, so they sent a few probes to go over and investigate." ”

"I see." Zhou Xin suddenly understood.

As he spoke, the probe was gradually approaching the confines of Space City. At this time, everyone saw that the speed of the probe had dropped significantly. At this distance, the space city, which originally looked a little small from a distance, began to grow larger. It is hard to imagine how the 100-meter-long individual buildings are closely arranged together, and the distance between the buildings is not more than 100 meters, and it is difficult to imagine how they can maintain such a distance without colliding. In the middle of these large buildings, there are some buildings that are only a few tens of meters long, or even more than ten meters in length, about the size of a space station, and I don't know what they are used for. At this distance, it was also discovered that each building was spinning at different speeds, looking like a spinning top.

"It's used to simulate gravity inside a building." Looking at the rotating space buildings, Zhou Xin guessed, and then he added, "Sure enough, in space, the circle is still a universal shape, even if the spaceship of this civilization is in the shape of a triangular prism, their space building is not to be cylindrical." ”

"Hmm." Atlas nodded, "If civil buildings were to take other shapes, there would be no way to simulate normal gravity, unless their technology could reach a higher level and simulate gravity without centrifugal force." ”

"Have you looked into any other ways to simulate gravity?" Speaking of this question, Zhou Xin asked Atlas curiously.

"I guess there was a theoretical study, but I didn't make a real thing." The little girl replied.

At this time, the probe had approached the nearest large building, and in the probe's footage, the surface of the space building was moving at high speed. At the same time, at this distance, everyone realized that the surface of this space structure was not a smooth curved surface as seen from a distance, but was made up of triangular planes of the same size reflecting faint blue light. Because the surface rotates at a relatively fast rate, they can't see more detail.

Zhou Xin couldn't help patting his head and teasing: "As a result, you still can't avoid the triangle when you get here?" ”

"There's no way, triangles are the characteristics of this civilization after all." Hearing Zhou Xin's words, Spred couldn't help laughing.

"Well, that's right." Zhou Xin's tone was a little helpless, and then he asked, "Atlas, where is the entrance to this space building?" How do I get in? ”

"We're not going in." The little girl's answer surprised Zhou Xin a little, and then she explained, "People want to investigate the buildings in the center first, and if these buildings are on the periphery, they will investigate later." However, if you want to enter, the entrances to these buildings are the same, at both ends of the cylinder. ”

As he spoke, the probe had already left the building in front of him and continued to move towards the center of Space City. Next, the probes passed several space buildings lined up one after another, watching the probes pass through the space buildings, Zhou Xin couldn't help but feel a strange feeling, feeling as if he was walking in a high-rise building.

Nearly half an hour passed, and new space buildings kept appearing in the rover's footage, which gradually approached and grew larger in the frame, until they disappeared to the edge of the screen, as if there was no end in sight.

After a few more moments, the probe adjusted slightly and moved on. After advancing some distance, on the left side of the frame, a corner of a space building is revealed behind a space building in the distance. Originally, Zhou Xin had seen this picture many times in half an hour, so he didn't think it was very strange, but when this building was exposed for a small time, not only Zhou Xin, but also other people's attention was focused on it.

In the screen screen, between the intact building and the half-exposed building, another corner is revealed, and it looks like there is another space building between the two buildings that have already appeared.

Seeing this somewhat unreasonable scene, Zhou Xin felt a little strange at first, but it didn't take him a few seconds for him to react, and the building that appeared first should be larger than the one in the middle. Sure enough, Atlas's next words confirmed what he was thinking.

"Brother Captain, the probe is approaching the center of Space City. If you see that space building, it's one of the central buildings in Space City. Atlas said, pointing to the building that was already half visible on the screen.

A few minutes later, the probe flew past the two space buildings in front of it, and the larger space building appeared in full in front of everyone.

Zhou Xin saw that this slightly larger space building looked slightly different from the previous one. Roughly speaking, it is still cylindrical in shape, but it bulges slightly in the middle and becomes thinner at the ends, looking a bit like an elongated wine barrel. Compared to the smaller space structures, it is almost twice as long, estimated to be more than 200 meters, and the diameter is much larger than those space buildings, especially in the middle, which looks much "fatter" than the slender cylinders. At the same time, behind this building, another space building similar in shape has also revealed a small half.

After adjusting its direction, the probe began to fly towards one of the ends of the space building in front of it, and after a while, the end of the space building appeared on the screen.

To Zhou Xin's surprise, one end of the cylinder that appeared on the screen did not look like a flat surface. Its edges are slightly curved and slightly raised, and in the middle there is a recessed square door with a few words clearly written on the door. At the same time, to Zhou Xin's surprise, this door is not open now, but closed tightly.

"What do those words mean?" Zhou Xin's first question was the obvious words on the door.

"That's a few numbers." Atlas replied, "I guess it translates to 003." ”

“003？” Zhou Xin said thoughtfully, "What kind of serial number is this, 003?" Is it the third? So there are one and two? After thinking about it for a while, he realized that he didn't understand, so he changed the question, "Has the probe found the entrance?" At the same time as he asked the question, the probe had flown up to the door and began to investigate the gate of the space building.

Flying to the side of the door, Zhou Xin saw how huge the door was, although it was much smaller than the gate on the satellite base, but its length and width were still more than ten meters, and the whole gate looked relatively new, far from being comparable to the rusty gate in the base. The camera's camera swept the door back and forth several times, and then it began to try to touch the door to inspect it, and after a while, the probe sent back an analysis report.

"Brother Captain." Atlas's voice rang out, "This gate is made of alloys commonly used in space, and there is nothing special about it. At the same time, the probe found no obvious entrance on this side, nor did it find any switches or other devices that could open the door. ”

Zhou Xin's brows furrowed, and he couldn't help but say to himself, "Can't you find a way to get in?" Now it's a bit harder. After thinking about it, he commanded, "Let the probe examine the entire surface and see if it will find anything." "Unfortunately, after the inspection, the probe still did not find an entrance to the interior of the space building.

"What's next?" Dart asked.

"Maybe we can wait a little bit, and when the other ships go in, our probes are sneaking in." Remembering Atlas's previous introduction, Spred opened his mouth to suggest.

"It's a pity." Atlas shook his head, "The activity cycle of the spaceships in Space City has long passed, and people haven't seen a few spaceships in the past two days. Moreover, not a single spaceship has been seen in the past twenty-four hours, and it is estimated that it will be difficult to wait for another spaceship to enter this space building. ”

"Is that so?" Zhou Xin's brows furrowed even deeper, and then he asked reluctantly, "Didn't the probe find a smaller opening?" If you can accommodate a small detector in the past, you can do it. ”

"Not yet." After the probe received Zhou's question, it still sent back a somewhat disappointing result.

"Don't you even have a small opening?" Zhou Xin was slightly disappointed.

"Is the only way to do it is to use violence?" Dart asked.

"That's definitely not going to work." Zhou Xin shook his head, "It has been determined that there are people in this space building, and it is too easy to have an accident if you go in directly and violently." Moreover, this place is still located in space, and if the violence is turned on, it may cause some unforeseen damage to the space building, and if it causes an accident to the aliens inside, it will be more than worth the loss. Then he thought for a while, and finally reluctantly ordered, "Let the probe search the larger area on the surface of this space building, and see if it can find any entrances or notches." ”

Not long after Zhou Xin's words fell, the screen moved again, and the detector began to carry out his commands. Then, more than ten minutes passed, and just as this side of the space building was about to be searched, the probe finally found a suspected entrance near the junction between this side and the side.

Looking at the triangular entrance that appeared on the screen, about the size of a wallet, Zhou Xin asked suspiciously, "What is this hole for?" Are you sure this hole can actually enter the building? ”

"I guess it's a vent used to adjust the posture of the building." Atlas guessed, "I don't know exactly where this hole leads, but I can try it." ”

"Okay." Seeing that there was no other entrance for the time being, Zhou Xin agreed to Atlas's suggestion......
