"Let's see what secrets this anomalous place hides. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ”

At this moment, several engineering robots appeared on the screen, and the Voyager had switched its perspective to the surface. Zhou Xin saw that the engineering robot on the screen had already begun to work, and after some inspection, the robot decided to open a gap directly above the cave.

Since the entrance to this cave is hidden nearly 100 meters underground, it still takes a long time for the engineering robot to dig to the entrance. The Voyager estimated that it would take four or five hours to dig up its intended position, and just as Zhou Xin was about to go back to sleep, Spred came in with Ralph.

"How's it going, has the investigation been completed, have you found anything abnormal?" As soon as Spred entered, he asked, "If you don't find anything out of the ordinary, forget it, it means that something may be wrong with the direction of our thinking." He then comforted.

"The probe found an anomalous cave." Zhou Xin replied.

"Oh? Did you find an anomaly at the end? Ralph said excitedly, "I'll just say there's nothing wrong with our speculation." Originally, I wanted to comfort Uncle Captain, but it seems that I don't need it. ”

Hearing Ralph call Uncle Captain again, Zhou Xin, with a black line on his face, said, "As for whether it is abnormal or not, we haven't been sure yet, but the shape of this cave makes us think that it can't be naturally formed." Then, Zhou Xin called up the previous profile and explained to them what he had just discovered.

"Straight down the cave?" Looking at the cross-section, Spred said to himself, "I really don't want it to be natural, this shape feels like a passage." ”

"Is there such a long passage?" Zhou Xin said suspiciously, "Actually, when I first saw this picture, I also suspected that this was a passage, but is there such a long passage?" You must know that although the detector in this place says that the detection range is a bit small, but at least it can detect the situation within five kilometers underground, you look at this cave on the map, this has extended to the range that the detector cannot detect, which means that the length of this 'passage' is at least four or five kilometers, what is the use of such a long 'passage'? ”

"How do I know, I always feel that the civilization that has transformed these special creatures is a bit strange, they only leave some secret information, and the civilization itself has not yet appeared, it feels like it is hiding something. So how could I possibly know what they thought, and maybe, the end of the 'passage' will give us the answer. Spred guessed.

"Hiding from something?" Zhou Xin repeated, "Indeed, even the information is so hidden, as if it doesn't want others to find out. But since they don't want to be discovered, what else do they want to leave this information for? ”

"Hell knows." Spred spread his hands, "We just have a few clues, and we can guess something." ”

"That's right." Zhou Xin said helplessly, "So far, we don't even know what this civilization looks like, what they are hiding is too secretive. It's so strange to feel that now we're just going one step at a time along the path that this civilization has given us. ”

"Forget it, it's useless to think so much now." Spred shook his head, "We'll have to follow the clues they gave us now." I think that since this civilization will leave clues, they must be pointing us to something. Well, the answer to everything may be hidden in the last thing we found. ”

Zhou Xin nodded, "Well, let's see if the clues they left behind are this passage, and if so, what will be hidden in the passage?" ”

After speaking, Zhou Xin yawned, he stretched and said, "No, I'm going to sleep first, and then call me when the passage opens." With that, he left the command module......

Five hours later, under the reminder of the Voyager, Zhou Xin woke up from his deep sleep, and after waking up, Zhou Xin wiped his face with cold water to sober himself up, and then returned to the command cabin.

It was close to noon on the ship, and in the command cabin, Spred and a group of researchers were busy, and although the exploration of the entire planet had been completed, they still had a lot of follow-up work to do.

After greeting Spred and the others, Zhou Xin focused his attention on digging the passage.

"Voyager, has the passage to the cave entrance been dug up?" Zhou Xin asked.

"Not yet, it is expected to be completed in 10 minutes." Voyager replied.

"Okay." Zhou Xin said, "Then let me see the situation first." ”

"Understood."

The screen in front of Zhou Xin lit up, and what appeared in front of him was a hole about one meter in diameter. Now the entrance to the cave was pitch black, and nothing was in sight. And near the entrance of the cave, a group of engineering robots are busy.

After a few moments, two engineering robots emerged from the hole, and the Voyager received a report that the road to the hole had been dug.

"What's going on inside?" Zhou Xin asked.

One of the engineering robots replied, "It's a straight passage, and nothing else has been found." ”

"Straight passage?" Zhou Xin was slightly happy, "Is it naturally formed?" ”

"Judging by the smoothness of the passage walls, it doesn't want to be natural." The bot answers.

"So what are you waiting for, hurry up and go in and have a look." Hearing the robot's words, Ralph next to him hurriedly urged.

Zhou Xin nodded, "Voyager, send a probe to go in and take a look." ”

"There's a problem here." "Due to the geological environment of this area, communication problems can arise more than a kilometer underground. The ship did not find a good solution for the time being. ”

"Isn't it okay to increase the power of communications?" Zhou Xin asked.

"It only adds a small amount of communication distance, which is not worth the cost, and increasing the power will cause a lot of burden on the detector." Voyager replied.

"What about the relay?" Zhou Xin asked, "Use several detectors as relays, and put one every kilometer to amplify the signal. ”

"Theoretically, yes, but using a detector for relay would result in a high signal delay."

"If the latency is high, let's be high, we have to meet the problem of being able to communicate first." Zhou Xin thought about it and answered.

"Understood, the probe is leaving."

The screen began to move, and the probe began to move towards the hole, and for a moment, the screen began to fade. Under the dim light of the detector, Zhou Xin saw that there were some potholes on the inner wall of the temporarily dug passage, and there was a unique texture of marble, which was obviously the result of the engineering robot's rush. At each distance the probe has advanced, metal supports can be seen to prevent the rock wall from collapsing. The probe walked about 100 meters or so, and Zhou Xin saw that the front suddenly opened up, and the passage suddenly became wider, and the inner wall of the passage became smoother. The probe had passed through the makeshift passage dug by the engineering robot and reached the passage that had already existed. Zhou Xin asked the probe to stop first, and then he began to carefully observe the passage.

It is a rather wide passage, about four meters wide and about three meters high, and the inner walls are polished so smooth that they can even reflect the light of the detector. In addition to the smooth inner wall, this civilization did not make too many decorations to this passage, what you see on the cave wall is still the texture of marble, the only difference is that every 10 meters or so, there is a small groove about 10 centimeters long on both sides of the cave wall, looking into the groove, Zhou Xin did not find anything in the centimeter.

Seeing the general appearance of this passage, Zhou Xin and Spred also communicated a little, and finally they agreed that this could not be a natural formation, that is, the location indicated on the DNA topographic map has a high probability of being this place. So they decided to follow the passage and continue their exploration.

The probe walked along this original passage for about ten minutes, and sporadic mosaics began to appear on the screen, and the probe took a few steps forward, and this mosaic became even more obvious, and it seemed that the probe's communication ceiling had been reached. At this time, the probe stopped, and after a while, the mosaic on the screen disappeared, and the probe as a relay had already departed. So, the first probe continued to move forward.

In this way, every 10 minutes, the first probe stopped a little to wait for the launch of the relay probe, a tedious process that lasted for about an hour, and just when Ralph was bored enough to start playing with his fingers, a stone wall appeared in front of the probe, which completely blocked the entire passage. Zhou Xin and the others searched for a long time on the stone wall, but they did not find a crack in it.

"Is that the end of our investigation?" Ralph was slightly excited, "After spending so much time, and finally finding a dead end?" ”

"Don't rush just yet." Zhou Xin comforted, and then he asked the probe, "Can you detect anything behind the stone wall?" ”

"The surrounding interference is too strong for the machine to probe the stone wall." The sound of the detector was tinged with a hint of interference.

Spred thought for a moment and said, "Try it close to the stone wall, maybe there will be something on the stone wall." ”

"What message do you mean there will be hidden on the stone wall?" Zhou Xin glanced at Spred.

"It's always right to go and see." Spred was noncommittal.

So the detector came to the stone wall, and the entire screen in front of Zhou Xinming was occupied by this stone wall.

Zhou Xin and the others saw that this was a very ordinary marble wall, and like the inner wall of the surrounding passage, the surface of this stone wall was very smooth, revealing obvious marble veins. Zhou Xin and they observed inch by inch along the stone wall, and after a long time, they found nothing, and finally they found that this stone wall was indeed a whole, and there was not a single gap on it.

Zhou Xin thought for a moment, and then commanded the probe: "Go to the edge of the stone wall and take a look." ”

The detector moved a few steps to the side, and the part of the junction between the stone wall and the inner wall of the passage appeared on the lens, and Zhou Xin took a closer look.

"Do you see a gap between the stone wall and the place where it meets the wall?" Zhou Xin asked suspiciously.

Spred and Ralph also looked at the place pointed by Zhou Xin, and after looking at it for a while, Spred replied with some hesitation, "There seems to be a gap, but it doesn't seem to be obvious, and it's a little difficult to see." ”

Zhou Xin commanded the probe: "Enlarge the junction between the stone wall and the wall. ”

The probes moved the camera closer to the junction, and they finally saw that there was indeed a gap between the stone wall and the inner wall of the passage, and this gap was so small that not even an ant could climb through it. Zhou Xin asked the probe to continue to explore along the junction and found that the gap ran through the entire junction between the stone wall and the wall.

Zhou Xin breathed a sigh of relief, "According to this view, this stone wall and the wall of the passage are not one, it seems that this stone wall should play the role of a door, and there should be something hidden behind the stone wall." ”

Spred nodded in agreement with Zhou Xin's opinion, "But how should we get through this stone wall?" ”

"Detector, scour the nearby walls carefully and see if there are any switches or something." Zhou Xin said.

The probe walked around the surrounding walls again, which were flat and smooth, and found nothing resembling a switch, not even a single groove that it had seen along the way.

Looking at this smooth stone wall, Zhou Xin had no choice but to say helplessly: "It looks like we can't find the switch, so we have to use some violent means." Call the engineering robots in. ”

After almost an hour, the engineering robots finally passed through the 5-kilometer passage to the stone wall, and then they began to open the stone wall.

The stone wall is about half a meter thick and made of marble, and the robot worked for about half an hour to open a hole in the stone wall with a diameter of one meter. After opening the hole, Zhou Xin let the probe pass through the newly dug hole and come to the other side of the stone wall.

On the other side of the stone wall, Zhou Xin found that there was no difference between the back of the stone wall and the front, it was still exactly the same passage, Zhou Xin asked the probe to look back at the other side of the stone wall, and found that the stone wall on this side was no different from the one he saw at the beginning. This made Zhou Xin very puzzled.

"Strange, why put up a stone wall in the middle of the passage if it's okay? And there's not even a switch. He muttered to himself.

"I guess it plays a sealing role." Spred guessed. "Maybe the switch of this civilization is completely different from what we know, or maybe the control switch is not next to the door."

After thinking for a while, Zhou Xin still couldn't think of any results, he shook his head and motioned for the probe to move on.

The probe began to move forward, and just about ten meters ahead of the probe, an accident happened.

A bright light suddenly appeared on the screen, and after the bright light flashed, the screen went dark and pitch black......
