After several hours of investigation, the probes sent back a lot of information, which naturally included a lot of images.

Through the images, it was clear to everyone that thousands of kilometers away from the ruins of Space City, there was something that looked like a half-cut round tube.

Many people exclaimed: "Isn't this a space city?" In the early days, there were many space cities in the shape of this kind of big cylinder! ”

Liu Yi and Mei Yuqi were also surprised, especially Mei Yuqi, she didn't expect that there were actually two space cities here, and in any information she consulted, there was no mention of such a cylindrical place.

This unexpected discovery rekindled everyone's emotions, and some suggested that it would be better to take a closer look at the battleship, and perhaps there would be a major discovery.

"Since this place doesn't even know about the people of Tuoyuanxing, it is likely that it has not been damaged, and it will probably be relatively well preserved, and it is of great value for investigation!" Everyone was excitedly discussing.

Liu Yi also felt that it made sense after listening to everyone's words, but he was not good at making decisions alone in this matter, so he had to ask Mei Yuqi's opinion.

"What do you think? Shall we continue to investigate the current space city, or will we go and see the accidental discovery first? Liu Yi asked.

Mei Yuqi couldn't make up her mind for a while, but fortunately Che Kuang came up with an idea and said: "I think it's okay to do this, first leave the probe to continue to explore this space city, and the battleship will go to the newly discovered ruins to have a look, so that there is no need to delay on both sides." ”

"That's a good idea, so let's do it!" Liu Yi said happily, and Mei Yuqi on the side also nodded in agreement.

Therefore, Che Kuang immediately notified the people below and asked the probe to continue the investigation mission, and the battleship immediately set sail and flew towards the newly discovered ruins.

The distance of thousands of kilometers is simply a lift of legs for a large battleship, and it will soon be near that cylindrical object.

From a distance, this thing didn't seem to be big, but when I got closer, I found that it was actually much larger than a battleship, and the battleship that everyone was riding on looked like a small point in front of this object.

"It's so big! It's really underestimated, this must be a space city! Everyone exclaimed.

Liu Yi sent the battleship around the behemoth so that it could be better observed.

Che Kuang immediately gave the order to go down, so the battleship took this large cylinder-like thing as the center of the circle and flew slowly around it.

As everyone observed, they found that there was not just one big cylinder, but four or five connected side by side, each of which was very large.

The two ends of these giant cylinders are sealed so that the inside of the cylinders cannot be observed, but most people believe that the interior must be a space city, as this shape was very popular in the days when humans first started building space cities.

"There is very little space junk here, and this thing does not seem to have been clearly damaged, indicating that it has not been damaged by war, I believe that the interior should be well preserved, it seems that it is the target we are looking for!" Liu Yi said with some excitement.

Mei Yuqi agrees with Liu Yi's opinion, but the origin of this thing is quite mysterious, which makes people a little uneasy.

"I think it's better to take a safe approach, probe it first, and then send someone up." Mei Yuqi proposed.

"Okay, now that we're here, we don't have to be in a hurry." Liu Yi nodded.

After that, the process was the same as before, first using the detector to carry out various surveys and measurements, and when everyone agreed that it was safe, the operation ship was sent to board the behemoth to find out.

The space team had not obtained anything too valuable in the previous missions, so everyone was holding back their energy to show off their skills in this place and find something truly valuable.

The operation ship slowly flew out of the battleship and headed towards the huge cylinder, and because there was no interference from space junk and various debris, the operation ship drove very close to the target in one breath before stopping.

Jiang Ping, as the team leader, took the lead out of the cabin, manipulating the work clothes and slowly leaning towards the huge cylinder. For the sake of safety, the team members deliberately tied Jiang Ping with a very long rope, so that in case of an accident, they could quickly pull him back.

Jiang Ping leaned towards this behemoth little by little, and the closer he got to this thing, the more he could feel its enormity, and in front of it, human beings had completely become a small ant.

"Three meters, two meters, one meter ......" Jiang Ping silently counted the distance in his heart, and finally his hand touched the surface of the behemoth.

"I'm here!" Jiang Ping said in an excited voice.

Jiang Ping's voice was heard by the people on both the work ship and the battleship, and everyone cheered in unison.

Next, Jiang Ping began to walk on the surface of this huge object, because it is very large, and when people walk on it, it is actually difficult to feel that it is actually cylindrical.

Jiang Ping walked along the surface of the large cylinder while observing, after analysis along the way, the surface of this thing is very smooth and flat, the process technology is very good, when it was built, it should be completed according to a very high standard.

Now that the surface was confirmed to be safe, several members of the work team climbed onto the surface of the cylinder and began to analyze the surface material using various instruments.

Liu Yi and the others kept listening to the report from the front in the bridge, and everyone's emotions became very excited, this accidentally discovered big guy is the best preserved space building so far.

At this time, the probe also sent back observations, and from the analysis results of the computer, this huge space structure is composed of five giant cylinders, each of which is about 5 kilometers long and 1.5 kilometers in diameter, which can fit even the largest ships in the world.

Mei Yuqi said: "It seems that this thing is likely to be a giant factory that builds ships, but I don't know who built it." ”

Liu Yi also agreed with this point of view and said: "Such a huge space factory, and it is so well preserved, it seems that it should not have been put into use yet." ”

Tang Jie was not very interested in this expedition, but now he was also very excited, and said in a loud voice: "If this big guy can be transported back, it can be turned into a very good factory, and now I want to know what is like inside!" ”

Liu Yi said with a smile: "Don't worry, you have to eat the meal one bite at a time, finish all kinds of exploration work first, and then find a way to get in." ”

Due to the discovery of this large cylinder, the previous investigation of the space city has been abandoned, and all manpower and material resources have been used to investigate the large cylinder.

In the following days, as the investigation progressed, the various materials about the cylinder became more and more abundant. An analysis of the exterior yielded an exciting result that the massive structure was probably designed with movement in mind.

So at one end of the cylinder, there was probably a power propulsion device that would allow the behemoth to fly.

If this analysis is true, this giant creature is actually a large space factory that can be moved at any time.

Although many mobile space factories have been built in the past, this is the first time that we have seen such a large scale.

Therefore, everyone is becoming more and more curious about the builder of this thing, and they want to go inside immediately to investigate, hoping to find the answer that everyone is looking forward to.

A few days later, the external investigation was finally completed, and the investigation began to enter the stage of internal investigation.

After previous investigation, several places that looked like entrances had been discovered, but almost everyone believed that the other end of the cylinder was the real gate.

If this place is really a factory for the construction of ships, then only the top part of the cylinder can be used for large ships to enter and exit.

It's just that we haven't found a way to open the door yet, and maybe we can only find the answers we need from within.

Jiang Ping's team found an entrance somewhere that looked like a maintenance passage, and they planned to enter from this place first, and then try to find a way to open the door.

Tang Jie volunteered to go in with the operation team, Liu Yi naturally refused to agree, the situation inside was not clear, how could he be willing to let Tang Jie take the risk.

However, Tang Jie's reason is also very good: "Who is familiar with the factory here, and who knows more about these complex mechanical structures than me, so letting me go with me can play a big role!" ”

After listening to this, everyone couldn't find a reason to object, and the people here really didn't know more about these than Tang Jie.

Liu Yi thought for a while and said: "In this case, then I will also go, on the one hand, I am learning about space architecture, and I also know more about various computer systems, and I may be able to restore the system here to normal." ”

Tang Jie saw that Liu Yi was going with him, and said happily: "Okay, you go with me!" ”

Che Kuang and Mei Yuqi on the side were very worried, and said in unison: "This is too dangerous!" It's better to let others in and have a look first, and you don't have to rush to take the lead if you want to go! ”

"Don't worry, this thing has been here for I don't know how many years, what danger can it be. Besides, we are not engaged in sabotage, so you can rest assured. Liu Yi comforted.

Mei Yuqi thought for a while and said: "If you must go, I will send a few people to follow you, they know more about the situation of Tuoyuan Star than you, and you can discuss it if you encounter problems." ”

Liu Yi nodded and said, "That's fine, it's indeed safer to have someone who is familiar with the situation." ”

So, Liu Yi and the others determined the list of people who entered the interior for the first time, and after some preparations, the operation boat flew towards the big cylinder with everyone on board.

After previous attempts, the work boat can now be docked on the surface, and everyone can walk directly on the surface of the large cylinder by simply stepping out of the work boat.
