Looking at these objects in front of him, Li Huihui knew that his life was temporarily saved. But it was still difficult and difficult.

After chatting with the system for a while, Li Huihui got down to business. The first thing was to stabilize the oxygen.

Li Huihui put on his spacesuit and struggled to drag the large range hood outside.

Although this long one looks like a range hood, the difference is that this machine is installed on the outside and the pipes are connected on the inside.

Looking at the instruction manual in his mind, Li Huihui studied the oxygen concentrator:

"The principle is the same as what I learned in junior high school. It is to extract a large amount of air into the compressor, and separate and prepare oxygen under high pressure and low temperature..."

"But this is indeed a black technology. The speed of oxygen production is too fast. This kind of speed and efficiency cannot be achieved by earth's technology."

Li Huihui installed the oxygen concentrator and felt a little more at ease. At least, he would no longer have to worry about oxygen in his survival cabin in the future.

The energy of this oxygen generator is solar energy. Compared with other solar energy, its ability to collect solar energy is too powerful. It is so powerful that a machine the size of a range hood can extract oxygen from the atmosphere.

A considerable concentration of oxygen is supplied to such a large survival chamber.

Awesome!

As the start button was pressed, the oxygen concentrator immediately made a roaring sound. That was the compressor in it starting to work. Just listening to this rich sound, you can tell that the power of this compressor is beyond

Unexpectedly powerful.

And at the moment when the oxygen concentrator started working, the display in the survival chamber turned green. Then I saw the reserve oxygen concentration in the survival chamber, which began to rise steadily according to the percentage.

After finishing the oxygen generator.

Li Huihui carried the water collector out again and placed it at the gate. This is the lifeline!

Absolute lifeblood!

Li Huihui spent two hours digging a hole and building a base for the moisture collector to prevent it from being blown away by the wind. The wind on Mars is very strong.

And the most important point is.

The base of the moisture collector is a vacuum kettle. The average temperature on Mars is minus 63 degrees Celsius, which is colder than the Antarctic.

If you carelessly put the water collector on the ground, you can also collect wool. A drop of water will have already frozen before it falls into the pot. What you want is water, not ice.

Dig a hole as a base. First, it can prevent the wind from blowing away the collector. Second, it can effectively insulate the kettle so that it will not be directly exposed to the surface...

After completing all this work, Mars' rotation has reached the opposite side. The sky is starting to get dark.

Li Guilai looked at the darkness around him, he couldn't see his fingers, there was no light at all.

Not daring to waste any time, he jumped back to his survival cabin quickly. In fact, it was not as dangerous as imagined, but Li was afraid of returning.

Don't talk about spending the night alone on Mars.

Before he was eighteen years old in his previous life, he would wake up his father every night...

After watching a ghost movie once, I would not dare to put my feet outside the quilt when I went to bed at night for a month.

He himself thinks that this is because he is cautious and has a good character. He can avoid most dangers.

But in theory, this is actually cowardly...

At night, Li Huihui turned on all the lights in the survival warehouse. He sat on the ground alone, staring at the darkness outside the window and a blue planet in the distance.

"In this night scene, only Mars can be seen, right?"

Li Huihui muttered to himself, now is the time when the Earth is closest to Mars, only 50 million kilometers away. It is precisely because of the proximity that the astronauts chose to return today. And seeing the Earth from this distance is simply shocking.

The blue earth is hovering and rotating in the night sky outside the window.

You can also see a small satellite rotating around the earth, that is the moon!

Inexplicably, he felt that this scene looked familiar...

After thinking about it carefully, isn’t this the same interface when logging into WeChat?

"well……"

Li Huihui let out a long sigh. His heart was extremely complicated. He was scared and nervous. He was full of confusion and unknown about the future. At the same time, he felt deeply lonely.

"System, do you think I have a chance to go back?"

"have!"

Li Huihui took a look before his eyes:

"They're going to save me, right?"

"dream."

The system complained ruthlessly, perhaps because the host was under too much pressure, and the intelligent system did not mind chatting with him more:

"Host, think about it carefully, are you worthy?"

Li Huihui was stunned: "What the hell do you call me worthy? Am I not worthy?"

"Speaking of which, I have to give you some popular astronomy knowledge. First of all, Mars and the Earth are both moving, and they are both moving around the sun. Does the host understand this?"

"I understand, I understand."

"When Mars is closest to the earth, the distance is only 50 million kilometers. But when Mars is the farthest from the earth, the distance is 400 million kilometers. This is because the earth is revolving and Mars is also revolving, and there is a time difference between them. And you

You know, if the Earth wants to land on Mars, based on Earth's technology, it must wait until Mars is closest to the Earth before launching a rocket and landing."

Li Huihui's heart beat faster: "So, Mars is the closest to the earth now!"

System: "However, no country has the ability to 'store' large-scale transportation rockets to and from it at any time. In other words, if you plan to land on Mars, the rocket needs to be 'made now'."

‘Gulu——’

Li Huihui swallowed his saliva: "Now, how long will it take to build a rocket?"

"From the early design, to the manufacturing of each component, to the assembly of the rocket, to the gunpowder engraving of the base, to the inspection of each component, to the launch, according to the technology of the earth, this cycle can take up to one year at the fastest! Now it is indeed

This is when the two stars are closest, but a year later, the distance will be very far. At that time, the earth will not have the technology to land on Mars."

Li Huihui said hurriedly: "Then we can wait until the next time the double stars are closest. By the way, how long will it be before the next time the double stars are closest?"

System: "Fifteen years."

Li returns: "..."

silence.

There was silence for a long time.

"Ahhhhh!"

Li Huihui let out a desperate cry and roared to his heart's content in the survival barn.

Fifteen years!

Fifteen years!

Fifteen years later, I will no longer be an eight-year-old child...

The system added: "Of course, judging from the technology of the five countries united, it is actually possible to build a large space rocket within five years to reach Mars. They can launch it from the earth and then fly around the earth for three weeks to store energy.

, hit Mars with a gravitational slingshot. After receiving you, it will circle Mars for a few weeks to accumulate power, and then hit back to the earth with the effect of a gravitational slingshot."

urgent!

Li Huihui asked: "Can I still be saved?"

system:

"But, back to the beginning of the topic. Do you think you deserve it? The five-nation alliance, within three years, this rescue rocket, the plan, and the total cost within three years must reach at least 10 trillion US dollars. Do you think

, are you worth ten trillion dollars?”

Li returns: "..."

Isn’t it worth it?

Woohoo...I'm so worthless!

"After all, is it really impossible for me to return to Earth? I won't really be a Martian in the future, right?"

System: "No, you have a great chance, but you need to create it yourself."

“How to create?:”

"If you can win a high-tech spaceship in the lottery, you can build a spaceship on Mars and drive it back by yourself."

Li returns: "..."

Pure nonsense.

Unless you give me tens of thousands of workers and then provide me with equipment, then it is still possible for me to install it according to the drawings.

There are no hairs on the rocks all over the place. How can you rub them with your hands?

Seemingly sensing Li Hui's depression, the system added:

"The spaceship is nothing more than shell material and fuel. There is no shortage of resources on Mars... What if you won a mineral training assembly line in a lottery? What CNC machine tool system you won, and what assembly line you won... Then the parts will come.

Is it done?"
To be continued...
