The mysterious tunnel is still extending. After knowing that there is no way out, the rescue team is a little depressed, but the team leader still encourages them to restore their fighting spirit a little. Now the lights are not installed at the original frequency, but are placed very far away. The communication instrument is also able to ensure the call, and it is no longer placed at close range. Fortunately, these things take up very little space and can get a lot.

Following the team leader, there are two electric vehicles, one with lights and other supplies, and the other with food and communication instruments. Now there are a lot of lights left, but not many communication instruments left. This is the last inventory of the moon base.

After another three hours of travel, the oxygen supply was not much, and the team leader's heart slowly sinks. Everyone knows that there is not much oxygen left, so they begin to consciously control the frequency of their breathing so that the limited oxygen can play its greatest role.

As time goes by, the communication instruments have been used up. Now everyone can only rely on close-range communication provided by the power armor. But everyone is keeping breathing now. Who has time to speak, so everyone is just walking quietly. But what they didn't expect was that a few minutes later, a golden gate appeared in front of everyone, and everyone looked at it in surprise. How could this be possible? How could there be a gate in this place? What would be there? The team leader asked everyone to stop. He was about to ask Lao Hong, but suddenly he remembered that Lao Hong could no longer contact him. The team leader glanced at the communication status of which group of people who were carrying Lao Hong on the projection. He originally thought that it would definitely not be able to communicate, but what the team leader didn't expect was that their group of states could actually be connected. What was going on?

The team leader did not think much, but opened the communication and asked, "Lao Hong, how are you doing there?" Lao Hong replied subconsciously, "Fortunately, there is a shortage of supplies. Alas? Can you make a call?" The team leader replied, and then turned on the positioning projection to find Lao Hong's direction. The projection showed that Lao Hong was standing at his feet, and the height distance between the two was three meters. The team leader asked, "Did you find anything there?"

"I discovered a gate, golden, the door was hidden. We are discussing whether we should go in?" The team leader thought to himself. Sure enough, the team leader said to him, "Get in, but you have to be prepared for defense. No one knows what will happen inside." Lao Hong responded and didn't say anything. He wanted to start walking inward. The team leader looked at the door in front of him. It was indeed the same as Lao Hong's. The gate was also hidden. The team leader didn't know why, but it did not prevent him from walking in with the team members. The golden door looked very moderate. The team leader pushed it with a try attitude, but unexpectedly, the door was opened! And it didn't use much force. Everyone looked in curiously. This was a hall, surrounded by this golden material, which looked golden. They entered one after another, but there was nothing inside and empty, but there was still a gate in the depths. The door was open, and it was pitch black inside and nothing was left.

Everyone had to walk inward and turned on the light. The dark gate was still golden material, but it was not shining. Some team members said, "Strange, why was there a bright hall just now?" When the team leader heard this, his heart moved and looked around. He found that there was something like a switch in a very high place behind the gate. The team leader used his power armor to jump and pressed the button. The passage really lit up! Everyone was startled, but seeing that there was no danger, he began to observe the surroundings. There was nothing around that deserved everyone's vigilance, but these golden substances seemed to be glowing by themselves, which was very magical.

The team leader looked around and suddenly found a black thing. The team leader built it and said, "This is a harmful gas detection instrument. It should be adjusted by the survey team. They have passed by here! But how is this possible?" Everyone was surprised when they heard it. You know, their supplies had long disappeared when they came here, and they would definitely suffocate to death halfway through the way. But now, everyone found that they were not only fine, but also came here lively, which was very magical!

The team leader thought about it and said, "Don't think too much, everyone be careful, let's continue to move forward." Everyone nodded and went forward. The team leader handed the instrument to the team members behind and put it on the electric car. After turning a few turns, he came to a gate again. The gate was also open. Everyone walked in and found that it was a large space with many golden chairs inside. The team leader looked for it. Sure enough, there was a pressed button next to the door. The team leader nodded and did not need to look. One of the teams had been here. After taking pictures of the surrounding scenes, they continued to walk forward.

Another passage, but the passage was lighted on. Everyone continued to walk forward. After walking for a few minutes, they arrived at a huge cave. When everyone looked in, they were shocked in an instant. They saw a spaceship as big as the size of the Divine Jade, which was parked there. Under the dark background of the cave, a faint fluorescent light flashed on his body. In front of him, dozens of people were also looking up at the spaceship.

This is a very beautiful spacecraft. The silver-white shell contains some pictographic words. It has an oval structure that challenges people's imagination. It stops there like an egg. Everyone can't help but walk forward. At this time, a few more people walked out of a passage below, which was Lao Hong and others.

The team leader was overjoyed and greeted everyone to gather, and then walked towards the people in front of the spacecraft. Not long after, the other party discovered the rescue team, but it was obvious that they were their own people, because everyone was wearing only the power armor, but the masks of the survey team were taken off.

The team leader asked in surprise if there is air here? There is really air here. After testing, the oxygen content is high, and other harmless gases also exist, which is not much different from the gases on the earth. After hearing this, the team leader took off his cover. Sure enough, there was no problem.

"What is this?" The team leader looked at the huge creature in front of him. The survey team leader looked at it and said, "It should be a spaceship. After testing, we found that this person may have been here for hundreds of millions of years, and humans did not appear at that time." More than millions of years. What a long history is this?

Although the team leader was curious about this, what was even more curious about was asking about oxygen here. The team leader of the survey team smiled and said, "In fact, there was oxygen not long after he came in, but everyone didn't pay attention. Did you see the fluorescence on this spacecraft?" The team leader nodded and said, "If you read it wrong, it's an energy shield!" Hearing this word, the team leader of the rescue team felt like traveling through time, and the energy shield. Although the earth has been researching so far,

But there was no result. However, what does this have to do with oxygen? The leader of the survey team knew his doubts and said to him: "In fact, it is very simple. Some channels here are protected by energy shields. Why is there oxygen here? Come with me." He said that, after he brought him to another gate, and after opening it, the team leader was surprised that there was a lot of water here. Not bad, a lot of water, and the blue waves were rippling. On the water, a huge instrument was still working.

"This is all the power source and treatment center of this base. He is responsible for decomposing water resources and decomposing oxygen to provide consumption. Of course, you see." He pointed to the two pipelines and said, "One is the output of oxygen, and the other is to generate gas, eliminate carbon dioxide, and restore it to water. I can't understand the technology among them. It is not a chemical method, nor does it seem to be physical. These pipelines are all over the base, and of course some are hidden. And in addition to this function, have you seen those pipelines?" The rescue team leader followed the direction of his finger and saw golden pipelines leading to all directions.

"This is a direct use of energy, but I don't know what energy is inside. However, this energy supplies the operation of the entire base. Through my observation, the entire base is now in a low-maintenance state, that is, the base is dormant, but we cannot wake up the base because we don't know what to do, and what I worry about is that there will be armed robots here!" The rescue team leader was shocked. This is a very possible thing. You must know that a base like this looks very important and there must be a security device. Even it is a luck that they can come in. I don't know if these devices fail, otherwise everyone may be attacked.

But even though I discovered this, what should I do in the future? I can’t wait here all the time, right? How do I get out? Both of them understand what each other means, and there is another question, why can the passage that comes only enter but not exit? So is there a passage that can only exit but not enter? Or can that passage be closed directly?

The problem now is the problem of going out. No matter how big the discovery here is, it is equal to zero if it cannot be taken out. The survey team has seen what strange roads will still be there when they go back. They dare not take the risk of moving forward and have to come back. The problem now is that they are trapped here.

"Now there is no way, so I can only look for it separately. I hope there is a way to go out. I hope there is a place to go out." After the rescue team leader said that, he turned to organize his own team members. After all, they have to be much more professional in this regard. Leaving professional issues to professionals is common sense. The survey team did not propose to look for them together because they are likely to cause trouble.

The biggest possibility now is in the hall with many chairs that I passed by. Is that place the command hall of the entire base? Of course, there are many questions, and the place is obviously abandoned. Why? This base looks very good, why is it abandoned? With such a civilization here, will the history of the moon be rewritten? What is going on with all this?
