A gate appears in front of the camera. Pen ~ fun ~ pavilion www.biquge.info

"Do you want to open this door?" Chang'e asked.

Zhou Xin hesitated for a moment, "Open it slowly and try it, if there is an air flow, close it immediately, and pay attention to protect the safety of the objects inside." ”

The camera is in front of the gate, Chang'e tried to pull the door, the door shook slightly and stopped, Chang'e tried to push the door again, this time the door did not shake, but opened a crack. Looking into the crack, it was pitch black inside, and I couldn't see the inside at all.

"No airflow was detected." Chang'e reported.

"Then open the door." Zhou Xin sighed slightly.

Chang'e gently stretched out her hand and pushed, and the door was completely opened, and under the light of the searchlight, the scene inside appeared in front of the camera.

It is a huge rectangular hall about 40 meters long and 15 meters wide, with several supporting columns arranged in order. On the walls on both sides of the hall are neatly arranged two rows of small doors, about 1 meter wide and 1.5 meters high. Directly opposite the hall there are three large and small gates, the largest in the middle of which is about 5 meters wide and 2 meters high, and a slightly smaller door on each side, 4 meters wide and 2 meters high. Most of the doors in the hall were tightly closed, only one or two doors were ajar, but due to the angle, Zhou Xin couldn't see what was in the room.

In the center of the hall are two rows of long tables, about 5 meters long and 1 meter wide, with rows of chairs on either side of the table. Between the two rows of tables there was a three-metre aisle, one end of which connected to the door they had just entered, and the other end to the largest door. In addition to tables and chairs, there are also some dishes and spoons scattered on the floor. Like the passage you just walked through, there was no light in this room, and relying on the searchlights of several robots, it gave the impression that no one had used it in a long time.

Chang'e walked over to a table and reached out to touch the table, and an obvious handprint appeared on the table, "According to the analysis of the thickness of the dust, this hall has not been used for at least three months. Chang'e said.

"Could it be ......" Zhou was confident and didn't dare to imagine it anymore.

"The scan has revealed a huge amount of underground space, and it is recommended that more robots be sent to assist in the investigation." Chang'e was silent for a while and reported.

"Agreed, pay attention to finding the surviving life forms of the civilization during the search, and rescue them under the condition of ensuring the safety of extraterrestrial life." Zhou Xin ordered.

……

After three days of detailed searching, the robot turned this floor of the underground facility upside down, and finally completed the search. Now, Chang'e is standing in this hall and reporting the search to Zhou Xin.

"After three days of searching, we have completed the investigation of this level, and now I will report back to you on the specifics of this level." Chang'e said.

"This floor?" Zhou Xin asked, "So, this underground facility has several floors. ”

"This will be mentioned in the next report."

"Okay, you go on."

"The hall I'm in right now is presumably a cafeteria." Chang'e continued, and then the camera turned to the small doors on both sides, "There are rows of small rooms on each side of the cafeteria, and from the furnishings of these rooms, it can be inferred that some of these small rooms were once kitchens, another part was a storage room, and a few things were places to put miscellaneous items, which can also indirectly prove that this hall was once a canteen or something." ”

The camera continues to move, and Chang'e comes to the gate opposite the entrance gate. Stretching out her hand to push open the door, Chang'e said, "This door is connected to another passage, and on both sides of this passage is a series of small rooms lined up, which, through investigation, were once the residence of these beings. Casually pushed open one of the doors, Zhou Xin saw at a glance that there was a bed in the small room, this bed was a little small, about enough to accommodate a person about 1 meter to lie on it, there was a set of tables and chairs next to the bed, and a small flowerpot-like container was placed on the table, and there was a monitor, and the monitor had fallen on the table. Chang'e walked to the table and picked up the flower pot, which Zhou Xin saw had some dry plant remains inside.

"It used to be planted with plants from this planet, but due to the lack of air here, these plants are dying of dehydration." "In the other rooms, we found some small animals, even the corpses of extraterrestrial beings like in the video, without exception, these things that were once living things have been dehydrated and turned into dried corpses." Examination of the dried corpses revealed that they had died of lack of oxygen, including the critters, suggesting that there had been a terrible air leak in this level of space after the planetary apocalypse. Placing the flower pot on the table, Chang'e turned her head and walked out of the small room.

"That being said, the people of this vault were not spared in the end." Zhou Xin sighed.

"It can only be said that the people of this layer have not been spared." Chang'e continued to walk along the passage, walked about 100 meters before coming to the end of the passage, there is also a gate at the end of the passage, Chang'e stretched out her hand to push open the door, and another hall appeared in front of her, this hall is slightly smaller than the hall that entered the door at the beginning, but this hall is empty, and even the supporting columns are sparser than the first hall. There was something on the wall around the hall, and because the light was too dim, Zhou Xin didn't see what it was.

"There is also a hall next door to this hall, and the function of these two halls should be similar to the recreation room and sports room." Chang'e walked to the wall, picked up a ball and put it in front of the camera for Zhou Xin to observe. The ball is about the size of a football ball, slightly concave where Chang'e's fingers touch, and it should be elastic. Putting down the ball, Chang'e walked to a large door on the side of this room, opened the door, and another hall appeared in front of Zhou Xin's eyes.

This hall is more furnished than the next door, with rectangular tables at intervals, some with nets on them, and others with chessboard-like patterns on them, although they do not have anything on them.

"According to the database information obtained, the contents of these tables are some of the table games of this civilization." Chang'e explained.

Back in the sports room next door, Chang'e walked to another door opposite the entertainment room next door, opened the door, and another passage appeared in front of the camera. Unlike the passage, which was full of small doors, there were only four doors on the walls.

"These rooms are functional rooms such as conference rooms, and after careful investigation, there is basically nothing left in these rooms, and the remaining things are discarded in a messy manner, as if they have hastily retreated after learning something." Chang'e said, at this time, the screen turned, and a messy room appeared, with some paper items and other gadgets scattered on the floor, and even a few chairs were upside down, Chang'e explained: "This is the scene when we first opened this room, and now it has been sorted out, and the other rooms are basically like this." ”

Directly through these gates, Chang'e walked about 30 meters, and Zhou Xin saw the end of this passage, and at this end, a metal gate was standing there quietly. Walking to the door, Zhou Xin saw that there was a button-like circular object on the right side of the gate, and there was a display screen on the button.

"This is...... Lift? Zhou Xin asked suspiciously.

"The probe shows that there is a vertical passage behind this door, which should be the elevator system of this civilization." Chang'e replied.

"No wonder you were talking about this layer when you reported it." Zhou Xin suddenly realized, "Do you know how many floors this underground facility has?" ”

"We tried to start the elevator, but if the energy system was damaged or if they had blocked the commands from this level, the elevator couldn't work, not even the panels. Therefore, it is not possible to know the exact number of floors of this underground facility. ”

"Why don't you just open the elevator and go down."

"Because we didn't know what was going on, we didn't dare to open the elevator directly."

"Well, well done, let's finish introducing this layer first."

"At this point, the exploration of this level has ended, and according to the analysis of the traces left on this level, this level was once inhabited by between 120 and 150 people, and there were signs of living people living here at least three months ago. However, for some unknown reason, there was a serious air leak here, and all the lives on this level were hastily evacuated, leaving only less than 20 corpses of life that had not had time to retreat, and these corpses had been transported back to the scientific research laboratory for analysis. ”

"Well, I understand, then the next thing is to find a way to go to the second layer, is there any way?"

"The old way, the temporary air-lock, the engineering robot is already underway, but it is expected to take a long time to complete." Chang'e replied.

After another day, the robots finally opened the opening to the second floor, however, disappointingly, they found that even the second floor had an air leak, and the situation on the second floor was even more miserable than the first floor, people didn't even have time to pack up their things, the ground was messily placed with various daily necessities and other things, and there were some corpses lying on the ground, these corpses were all in the direction of the elevator, and when they arrived at the elevator door, there were more than a dozen corpses lying here. Metal tools were scattered next to the corpses, the elevator doors were ajar, and it seemed that desperate people had even destroyed the elevators on this floor. According to Chang'e's analysis, the second layer and the first layer should have had a disaster at the same time, and the source of the disaster should be the first layer, so the people on the first layer retreated first, but when the retreat was almost completed, the disaster expanded, so the people on the second layer hurriedly began to retreat, but it was too late, at least half of the people were left in this layer and died miserably.

Since the elevator on the second floor has been destroyed, the robots followed the elevator door to the third floor, and when they saw the elevator door on the third floor, Zhou Xin felt cold. The elevator door on the third floor has also been damaged, and there are more bodies lying in the door than on the second floor, and after investigation, there are more than 100 bodies lying on the third floor, and the time of the disaster was also three months ago.

Zhou Xin was completely disappointed, "Could it be that the disaster three months ago completely destroyed this underground facility, and in the end it was a trip in vain." Zhou Nobunaga sighed.

"Please don't give up hope." Chang'e comforted, "After investigation, it was found that the elevator shaft between the third and fourth floors was completely closed, indicating that after the disaster, the people on the fourth floor successfully prevented the disaster from continuing to deteriorate." ”

"Let's hope so." Zhou Xin's words were a little weak, "Have you completed the investigation on the second and third floors?" ”

"After five days of searching, the second and third floors have been inspected, and a total of 170 humanoid corpses, several small animal corpses, and some scattered materials and daily necessities have been found."

"Is there any valuable information? For example, the causes of the first three layers of disasters? ”

"No, the most of them are some trivial materials in life, and there are still a small amount of scientific research materials, but we have already obtained these materials, and there is no value in using them."

"Well, since I didn't find anything, it looks like I'll have to go to the fourth floor." Zhou Xin said helplessly.

"Yes, Your Excellency, Captain."

After another day of preparation, the preparation for opening the fourth floor was completed. Early the next morning, Zhou Xin got up early and sat in front of the command platform, and Zhou Xin silently prayed for the existence of a living person on the fourth floor.

The roar of the machine rang out, and in a few moments the passage to the fourth floor opened.

"Strong drafts detected." Chang'e standing at the entrance of the cave reported.

"There's air?" Zhou Xin was a little excited, "Come in and have a look." ”

Jumping down the hole, Chang'e opened a door, and the scene of the canteen appeared in the camera, unlike the canteen on the previous floors, this canteen was placed very neatly, giving people a feeling that it had just been cleaned up.

"There seems to be hope." Zhou Xin muttered to himself.

The camera moved to the table, and seeing the thick dust on the table in front of the camera, Zhou Xin's expression was stunned.

"What's going on?!" Zhou Xin, who had been there for a while, asked in surprise.

"No one is expected to have been active here for two and a half months." Chang'e touched the dust and said.

"What's going on on this floor?! Isn't there still air when it's opened? Zhou Xin hurriedly asked.

"In the analysis of air composition, the oxygen content in the air is only 5%, which is far lower than the living conditions of life in this civilization." A detection robot next to Chang'e reported the results of the analysis.

"How can it be only 5%!" Zhou Xin became more and more surprised, "Is there something wrong with their ecosystem?" If that happens, life in this shelter will be over! ”

"The conditions are insufficient to analyze." Voyager replied.

"Is further investigation needed?" Chang'e asked.

"Of course, we have to continue to investigate, at least to know what is going on."

"Understand ......"
