The model of the arc star has actually been done very accurately, after all, the unmanned exploration spacecraft has circled around it for I don't know how many times, and basically all the surfaces have been seen clearly.

The reason why "basic" is used here is because there are secrets on this arc star, or there are prehistoric ruins, some of which are clear at a glance and can be seen directly in space, but some places are covered by clouds and fog all year round, and some places have strong signal interference, resulting in many detection behaviors that cannot be carried out normally.

There are even places where the holographic projection is directly overlayed, and the outside looks the same, but the inside is another.

If it weren't for the fact that it had been too long, the surroundings of those places had changed, and they didn't fit well with the holographic projection, and the unmanned exploration spacecraft wouldn't have noticed it.

Therefore, the model of the holographic arc star in front of Dong Chen is not only the natural scenery and the humanistic buildings of this generation of arc people, but also many ancient ruins are marked in red.

Looking at Dong Chen's puzzled expression, No. 1 clicked on the mountain again, and then a red model appeared under the mountain.

This model located in the mountains and underground has only a general shape, and it does look like an underground structure, not a cave or something.

"Although it is not clear what exactly is inside, after comparing the layout of the building, it is very likely that it is something similar to a civil air defense project or a secret research institute built by an earth country."

"I think we can explore it when we get there, and that's a bonus."

"Originally, I was going to explore those known ruins alone, but I didn't expect to find a new one just now, just near the chosen landing place this time, maybe there will be something to gain at that time."

Dong Chen had no opinion on this, and also clicked on the location and said, "Okay, then it's set here, let's start the landing procedure." ”

"Okay, sir, let's start the landing procedure now." No. 1 saluted Dong Chen seriously.

Seeing No. 1 saluting himself in a one-of-a-kind arc military uniform, Dong Chen also shook his head helplessly, feeling that No. 1 was getting better and better at playing, and it was quite like that.

But he went with No. 1, as long as she was happy.

And after the words of No. 1 were finished, the "cigar" that was no longer on fire in the orbit of the arc star broke apart from it, one of the sections remained in place, and the other section flew towards the arc star, and the one that flew out was the landing spacecraft that Dong Chen was riding.

Well, it's still a cylindrical type, but it's relatively short.

Due to the new technology, the landing spacecraft will not fall towards the target in a hurry, but will maintain a relatively low and stable speed and fly towards the destination, and also turn on the optical stealth system, completely hiding the spacecraft's figure.

This spaceship is equipped with an anti-gravity device that has been obtained in Area 18, but the anti-gravity technology among the ship-selling citizens is not very perfect, so there are spaceships like the Constellation class, and when they land in the planet's atmosphere, they also need to turn on auxiliary turbofans to provide a certain amount of lift and power.

The landing spacecraft is also similar in configuration, with anti-gravity devices to cancel out some of the gravity, and a relatively small ion engine to provide lift and power, compared to the turbofan can only work on planets with atmosphere, but the ion engine can cope with various situations.

During the flight, Dong Chen is still receiving all kinds of information, especially now that he has flown into the atmosphere, there is less influence of atmospheric refraction and cloud occlusion, and it is also closer to the ground, and the reconnaissance equipment on the spacecraft can obtain images and information more clearly.

When flying over the coastline, Dong Chen pointed to the latest virtual map and said, "No. 1, you see that there are basically no cities or tribes on their coastline, and even if there are, they are in relatively high places, or directly on high cliffs, it seems that the impact of these two satellite systems on them is not small." ”

"That's right, sir, after all, when the two moons coincide or are close together, the tidal movement becomes relatively violent, and then when the tide rises again, those places close to the shoreline are still dangerous." No. 1 stood next to Dong Chen and said.

"Well, and this dual-satellite system affects more than that, it seems that their religion has something to do with this, you seem to have told me that they often fight each other because of the worship of different moons?"

Looking at the orbiting system of the small planets and moons next to the big map, Dong Chen thought back and asked No. 1.

After listening to Dong Chen's question, No. 1 found a few videos and pictures and said to Dong Chen, "Sir, you may be mistaken, I definitely didn't say such an accurate conclusion." ”

"We have similar video recordings, and after analysis, we believe that this is the reason, but there is no confirmation about this matter at present."

"After all, our observation method is to conduct reconnaissance from space orbit, and it is okay to observe the general direction and big data, but if we want to make specific observations and learn their culture and language, we can't do it at present, after all, the exploration spacecraft is too far from the ground."

When Dong Chen heard it, he felt that the unmanned exploration spacecraft was actually not much different from an artificial exploration satellite, that is, it was swaying back and forth in orbit, and then checking the situation on the ground.

They were given the task of searching for travel energy in space, and they were not designed to enter the atmosphere, so they did not install equipment in this area.

Even if the manufacturing of these things has no cost for Dong Chen, theoretically it can be perfect if there is enough time, but it is really not enough time.

I didn't think of this kind of thing at the time, and finding the wormhole was an accident.

At that time, they just wanted to find the "energy source" as quickly as possible and let Dong Chen open the third game world, so after installing the necessary equipment that they needed, they were allowed to set off, so they could only wander in the low-earth orbit of the arc star.

This situation has led to a lot of problems, they can know that there is life on the arc star, and it is intelligent life, and they can also basically know the development stage of society and science and technology on the arc star, and they can't go into details.

The most important thing this time is to find a lot of prehistoric relics, those are all treasures that the Arc Star has been accumulating, for Dong Chen personally, it is more important than finding the Arc Star, a relatively perfect life planet for human beings.

Now for Dong Chen, he is here to travel, by the way to carry out some exploration activities, or directly archaeology, or interstellar archaeology.

It's just that he...... No certificate.

Just as he was thinking about whether this was an "interstellar tomb robbery" or "interstellar archaeology", the number one next to him reminded him, "Sir, we're going to land." ”

Hearing this, Dong Chen looked out, and sure enough, he saw that the spaceship was very close to its destination, and below it was a dense forest, and a small river zigzagged through the entire forest.

The hill I saw before was right in front of you, and as soon as you crossed it, you would be able to land.

Looking up again, there was that big city in the distance, and it was also one of Dong Chen's destinations.
