Dong Chen's residence and laboratory are the most advanced rooms in this space station, there is no doubt about it.

After he decided to come to the space station for permanent residence, he quickly made enough equipment from the underground base, and then transported it to the Xintiangong space station by the aerospace transport plane for assembly.

Moreover, no workers were used in the installation process, all of them were installed and decorated by engineering robots, and the decoration of the place where Dong Chen was going to live and the place where he was going to do the experiment was completed in the shortest possible time.

Dong Chen will have two residences in the entire space station, one is in the main axis construction area, which is located in the Arc Light Group's own land, where there is no gravity, but it occupies a large space volume.

The other place is in the simulated gravity zone under construction, which has almost the same simulated gravity as the Earth's gravity, but a little smaller than the place here in the main axis area, after all, the simulated gravity area is not very large.

Both of his residences are very well located, just like here in the main axis area, not only do they occupy a lot of volume, but the interior decoration is also very good, and there is a large picture window.

This viewing window is not as exaggerated as the observation deck, but in the private cabin, it is definitely the largest, and the window is facing the earth, which is very relaxing.

The unpredictable clouds are not the same for a moment. Magnificent space sunrises as many as a dozen times a day, and a mysterious atmosphere that illuminates before the sun rises. And when passing by the night of the earth, the civilization of the lights of the ten thousand lights also looks very pleasing to the eye.

As for Dong Chen's personal safety, there is no need to worry, if he is still likely to be attacked on Earth, then no one on the space station can really hurt him.

There are so many means of attack on Earth that even if you take precautions, you may be overlooked.

And Dong Chen must have many people on the earth who want to attack him, some have already carried it out, and some people are still planning, but there are no successful examples for the time being.

It will be safe in space, there are few means on the earth that can attack space now, and now with the blocking of space junk patches, those already scarce attack methods are even less threatening to Dong Chen.

Even if their missiles really hit, then Dong Chen's safety is not any problem, those engineering robots that are busy outside are not decorations, and their multi-functional laser welding machines are not only used to weld steel plates.

Following the staff to his own turf, looking at the fully renovated residence, Dong Chen said to the staff who brought him, "Okay, I'm fine here, you can go and get busy." ”

"Okay, chairman, you can rest. If you have any questions, please tell me, and we will come over shortly. ”

After the staff who led the way left, the door of the residence closed automatically, and Dong Chen walked to the window and looked at the earth and asked, "No. 1, are you there?" ”

As soon as Dong Chen finished asking, No. 1's voice sounded in the room, "It's always there, sir." ”

"Very well, how's the latest exploration going? Have you found the source? Dong Chen asked.

"The energy concentration continues to rise, and it has been in a state of slight acceleration, and the specific source is still being found, but we have detected areas rich in energy." No. 1 said to Dong Chen.

Dong Chen became interested as soon as he heard this, he hadn't found this kind of change before he took off from the earth, and now it's only been half a day, and there has already been this kind of change.

He took two steps back, sat down on the couch in front of the floor-to-ceiling window, and said, "Give me the specific data image and I'll show it." ”

"Yes, sir, it has been sent to your glasses monitor."

With the reply of No. 1, Dong Chen saw the specific information and data map sent by it, among which there was a chromatogram of energy concentration around the earth, which could very intuitively see the energy enrichment situation around the earth.

And this map and those specific data all point to a general direction, and the farther away from the Earth in this direction, the more concentrated the energy concentration becomes, but now the detection range of satellite detection equipment is limited, and there is no data after detecting half the distance between the Earth and Mars.

After reading it, Dong Chen said, "Are you implementing any follow-up plans?" ”

"Yes, sir, due to the lack of materials and manufacturing equipment in the space station, and the fact that the miniature orbit change engines on the satellite are not enough for long-distance travel, the underground base is already manufacturing propulsion."

While explaining the plan to Dong Chen, No. 1 sent the information to Dong Chen and said, "There are a total of four sets of propulsion devices, and after the manufacturing is completed, I will launch them and combine them with the four exploration satellites, and then they will become unmanned exploration spacecraft to carry out close reconnaissance missions." ”

Dong Chen looked at the design drawings given by No. 1, which was called a sweat.

Although No. 1 doesn't have the kind of artistic design and can't make the design full of spirituality, it's still easy to design according to practicality.

Although it is not very good-looking, there is really nothing to say about the practicality, and after Dong Chen prioritized this task, the design materials of No. 1 are also unambiguous.

The energy core of the propulsion device uses a micro nuclear fusion core made in the underground base, and it uses a new technology that Dong Chen and No. 1 have upgraded together, which is a new model that is more suitable for real-world use habits.

The raw materials used are some nuclear materials that Dong Chen got from the radiation world, because Dong Chen has no source of nuclear materials here in the real world, and the moon base is still under construction, and the mining of helium-3 has not yet been settled, so he can only use the inventory that Dong Chen brought back first.

The engine of the propulsion unit is also a small ion engine that they have newly upgraded and researched, and the speed is also quite good, although the speed is not as fast as the "Black Hawk" after many upgrades, but it is much faster than the current series of aerospace aircraft.

With these two main parts, the other linkage parts can be put together by finding some ready-made modules from the material library, and this has led to a space propulsion device with "decent" performance.

Well, the performance is indeed decent, with these technologies, if you want Dong Chen to participate in the redesign, give him some time, there will definitely be better results.

But now that time is pressing, let's waste some performance and waste some performance.

After all...... The "decent" mentioned here is only relative to these technologies, and for the earth, it is also crushing level.

In the following time, Dong Chen found that his original calculation was not very correct, and it was not that he could increase by 0.2% or more in one day in space.

The reason why he went into space and rose by 0.2% directly was also because there was accumulation before, and after the absorption was completed, it would accumulate again, and it would not be absorbed until it reached that concentration.

In this case, his previous calculation time was incorrect, and at the current rate of energy growth, if he had simply stayed in the space station to absorb energy, it was estimated that it would not be until several months before he reached 100%.

But in addition to this, there is also good news, the growth rate of energy is not regular, sometimes fast and sometimes slow, but overall it is getting faster and faster.

And there are also some eyebrows for the news of the energy source.
