The probe moved forward more than a hundred meters, and the crack that had been spreading forward finally changed. Pen ~ fun ~ pavilion www.biquge.info

In the detector's lens, the original crack suddenly stopped here, and at the point where the crack stopped, a new crack was cut across at 90 degrees from the original crack. The width of this new crack is almost the width of a palm, and following the direction of the camera, the new crack extends to the left and right, until it extends beyond the frame, and at first glance, it seems that this crack is not natural at all.

Choosing a side at random, the probe continued along the crack, and this time it was about eighty or ninety meters away before it saw the end of the crack. The unnatural feeling is even more pronounced when you look at it here, as the crack turns at a right angle as it extends here, and then continues in a straight line into the distance.

Looking at the picture on the camera, Zhou Xin couldn't help but speak: "Such an unnatural crack, they actually didn't cover it up and just exposed it directly on the ground." After thinking about it, he understood, "The crack itself is not very obvious, and if we hadn't seen with our own eyes how the entrance opened, it would not have been easy to spot." ”

Next, the probe spent about half an hour inspecting every crack, or the crack of the entrance door, but found nothing. All the cracks were almost the same palm's width, and nothing could be seen except for the light shining from the probe, not even the ship that had flown in not long ago, and all that could be seen was darkness.

However, after the calculation of the probe along the way, Zhou Xin and they also knew the size of this gate, which is a slightly rectangular gate, the gate is about two hundred meters long and about one hundred and eighty meters wide, which can accommodate two or three spacecraft to pass through side by side. The gate is more than a meter thick and is made of the most common rock found on this satellite. During the inspection of the gate, the detector did not find any opening device, not even the mechanism that moved the gate, and it appeared to be hidden behind the door.

After some investigation of the gate, the work of this probe has come to an end for the time being, and the next step of exploration can only be resumed after the arrival of the next small probe.

After another two hours, several ordinary probes arrived at the entrance with some small probes. Next, they began to investigate the base underground.

In the process of the probe going to the entrance location, Zhou Xin discussed the investigation route with others. At the same time as the probe landed, they dispersed in different directions, lining up along the edge of the entrance that had just been detected. Then, one by one, the small probes were released, and from the cracks, they began to try to enter the base.

Without incident, the small detector was able to slip through the crack and reach the other side of the gate in a short time. However, as in the previous case when seen through the crack, nothing could be seen inside, only a small area within the range of the detector's light.

Sticking to the door, the detector first probed the back of the door, and from this direction, the man-made traces were very obvious. In the picture, everyone can see that a large number of very obvious large metal structures are fixed behind the rock gate, and in one of the shots, Zhou Xin even sees a very long and wide structure similar to a guide rail being installed on the edge of the gate. It is worth noting that all of the structures have severe rust on the surface, and some even have defects, and it seems that these structures are some years old.

Seeing this situation, Zhou Xin couldn't help but wonder: "How long has this base existed, and why does the gate look so badly damaged." ”

"From the analysis of the degree of corrosion, the life of these metal components is more than 100 years." Seconds later, Voyager came up with the results.

"More than a hundred years?" Looking at the picture on the screen, Zhou Cheng thought with his chin in mind, "Could it be that this base has been around for so long?" As he pondered, he motioned for the probe to continue investigating.

In less than twenty minutes, the probe had already examined the back of the gate, and in addition to various metal components, the probe found a large device on both sides of the gate that appeared to be used to open the gate. These devices, like those metal components, were all badly corroded, and if he hadn't seen the door open before, Zhou Xin would have even thought that these devices would have been useless for a long time.

After investigating the back of the gate, the detector changed direction and began to investigate inward along the cave wall, and when he saw the cave wall for the first time, Zhou Xin felt a little surprised.

On the walls of the passage, you will see ordinary rocks, which is not the most surprising. The most surprising thing is that the entire wall looks untrimmed and completely uneven. Also, this is not the footage of a single detector, all the walls that can be seen in the frame are like this. It is also worth noting that although it can be inferred from the gate that this passage must have existed for a long time, there are still obvious traces of mechanical excavation on the entire wall, so it is clear that this passage was not naturally formed.

"This passage-" Seeing the picture on the screen, Zhou Xin's brows furrowed, "It looks a little shabby-"

"Maybe it's just the periphery of the base, so they've just dug a little bit of a passage to get out?" Spred guessed.

"Hmm." Zhou Xin nodded casually, but looking at the expression on his face, he obviously didn't agree with Spred's opinion.

Since there was no way to know why the channel wall was like this, Zhou Xin had no choice but to let the probe continue to explore. Along the wall of the passage, all the probes advanced towards the depths of the passage almost simultaneously, and after advancing a distance of about 100 meters, Zhou Xin suddenly discovered another place that made him wonder.

"Why don't you see any lighting in this passage?" He asked.

That's right, as the probe progressed, Zhou Xin kept staring at the images sent back by the probe on the screen, but he didn't see any objects similar to lighting devices on the wall at all. Along the way, he didn't even see any man-made objects. From beginning to end, the rock walls are shown in more than a dozen shots. Aside from the traces of artificial excavation, there are no other clues here that would alert everyone to the presence of aliens further down in the passage.

Under Zhou Xin's reminder, everyone also discovered this, and suddenly, everyone felt a little puzzled.

"yes, how could the passage itself be unlit?" Spred muttered to himself, "How did those ships get through this passage just now?" Is it just the lights on the spaceship? That's weird, isn't it? ”

"Could it be that the detector missed something?" Zhou Xin was also muttering to himself, "Or do you mean that all the detectors are not illuminated?" But then he shook his head, "No way, the probability of this happening is too low." Still, in his heart, he decided to let the probe search the route it had taken for a while.

"Or is the lighting hidden behind the wall? It only shows up when it's in use? Dart was also speculating.

"It's possible." Zhou Xin nodded, "Let the detector look for it on the wall in a while, it can't even be that there is no such thing." As he spoke, the probe continued to move forward, but the walls were still bare, and nothing was found.

After a while, the probes had penetrated about 500 meters from the surface, but they still found nothing, and in front of them, there was still a dark unknown space.

This time, Zhou Xin was not only puzzled, but also began to have some doubts in his heart. He began to wonder if the previous ships had entered this passage, otherwise he wouldn't even be able to see the traces of entry, but he didn't express his suspicions, but continued to look at the screen screen. And next to him, Spred's brow furrowed, and he showed an expression that wanted to say nothing.

After advancing some distance, many people in the command cabin began to see that something was wrong, and they began to talk in low voices. At this time, Dart asked suspiciously, "Strange, why can't you even see those spaceships, where are they gone?" ”

As soon as his words fell, the image on the screen began to change slightly. In several shots, a faint light began to appear in the pitch-black passage far ahead. As the probe continued to advance, that faint light appeared in more and more shots. Glancing at the light that appeared in all the images, Zhou Xin found that the shape of the light spot in the pictures sent back by each detector was the same, and it seemed that all the detectors should have captured the same thing.

After advancing nearly two hundred meters, one of the probes finally reached the location of the light. In the footage of the probe, everyone saw that the object that emitted the light was a rectangular sign, and there were several unknown words on the sign, which Atlas recognized, and the text on the sign translated into only one word - home.

"Home?" Zhou Xin repeated suspiciously, "Why is this word hanging here?" ”

The crowd was also surprised, and they couldn't figure out the reason for the discussion for a long time. While they were discussing, the probe came to the sign and began to investigate it. After turning around the sign, Zhou Xin saw that the sign was fixed to the wall by a metal bracket, just like the metal seen behind the rock gate before, the entire metal bracket had been very rusted, and there was a slight twist. At the same time, he also discovered that the sign was just an ordinary glowing sign, and there was nothing else worth investigating on it other than a few alien characters. The whole brand was not connected to anything other than the metal bracket, and Zhou Xin didn't even see how it glowed. However, although this is just a simple brand, when Zhou Xin saw it, he couldn't help but breathe a sigh of relief in his heart, the existence of this sign at least shows that the direction they are exploring is not wrong, and the place where this passage leads should be someone else.

While the probe surveyed the sign, the other probes continued on their way, but it wasn't long before all of them were stopped by a wall that appeared in front of them.

By the time Zhou Xin's attention turned back from the sign, the other probes had already begun to investigate the wall. Seeing that the detector was stopped, Zhou Xin was not particularly surprised, and he began to observe the objects that had just appeared in the passage on the screen.

This time, standing in the way of the probes was a metal wall, visible from the vantage point of view of each probe, which was deeply embedded in the tunnel wall without a single gap. This is not the most concerning, what makes Zhou Xin feel most concerned is that the surface of the metal wall can still see obvious traces of rust, and at the same time, it can be seen that the wall surface is also not very smooth, with a slight twist.

"Huh?" Just as Zhou Xin scanned the screen on the screen, Atlas said suspiciously, "This wall-?" ”

"What's wrong with this wall?" Zhou Xin asked as he observed.

"It seems—" the little girl's tone hesitated, "wait a minute, and they'll let the probe take a closer look." After a while, she said in a more certain tone, "Sure enough, Brother Captain, this wall is not made of a single material. ”

"Isn't it made of alloy? What's so strange about that. Zhou Xin's tone seemed a little disapproving.

"No, that's not what people mean." Atlas shook his head repeatedly, and then explained in detail, "What they mean is that the whole wall is divided into different parts, and each part is made of different alloys, and these parts of different materials are forcibly put together to form this wall. ”

"No, how could it be like this." After listening to Atlas's explanation, Zhou Xin was still a little unconvinced.

"That's really the case." The little girl affirmed, reversing the order of the images sent back by the detectors on the screen, and stitching together several of them. After the pictures on the screen were reassembled, Zhou Xin noticed something unusual.

In the picture where Atlas is put together, some differences can be seen between the adjacent walls. However, due to the slight differences and the fact that the light of the small detectors is not so bright, this difference can easily be overlooked if it is not compared side by side.

After seeing this picture, everyone felt a little strange......
