Chapter 3 Asteroid Factory, 7 years later

Yan Xia hid in a hurry.

Fortunately, the spacesuit has a multi-layer structure and was not completely penetrated.

He returned to the cabin and immediately gave instructions to Ella.

"Photographing the direction in which the laser beam is coming may be the surviving people."

He was a little panicked just now, and now he's a little excited.

Ella turned the camera around while analyzing the previous scene where Yan Xia was hit by a laser beam.

"Yan Xia, the direction of the laser beam has been analyzed."

"Coming from the direction of Sagittarius from the outer solar system, the laser beam energy is extremely dense and is not a technology that the earth can control."

"The speculative data shows that there is a 100% possibility that it comes from an alien civilization, and a 97.28% possibility that the distance of the laser beam is less than 5 light years."

This is undoubtedly a bucket of cold water in the harsh summer.

Alien civilization.

There is a high probability that it is due to gamma rays. Some alien civilizations have observed that the direction of gamma rays reaches directly into the solar system.

So 100 days later, the alien civilization fired a laser as a detection. 100 days after the gamma rays reached the earth, the laser also arrived.

"That is to say, the laser itself is used for detection. Can the alien civilization analyze the spacecraft and me through the reflection of the laser beam?"

Ella didn't even calculate this time.

"yes!"

"The civilization level of this alien civilization significantly exceeds that of human civilization. The question you asked Yan Xia is very likely."

Yan Xia had a sense of crisis.

If this is the case, then alien civilization will definitely enter the inner solar system to explore.

By then, he will directly meet this alien civilization.

"It's surprising that after such a short period of time, we encountered an alien civilization."

"Perhaps, life is really widespread in the universe, and it is just a coincidence that humans can develop without being discovered by aliens."

There's no use thinking about it now.

You have to develop yourself to be able to face aliens.

Yan Xia powered on the robot and it lit up.

It moved around a bit, used its claws and drill, and it seemed to go well.

Then it jumped out of the cabin, used the toothpick-sized holes in its body to correct its position, and landed steadily on the surface of the asteroid.

The robot has no camera and everything is directly controlled by Ella.

It inserts the drill bit directly into the soil and starts working.

Most of these asteroids were separated from the destruction of planets, or have experienced countless violent collisions. Their surfaces have been baked by extremely high temperatures, and there are almost no impurities inside.

The 3D printer can print metal and comes with a very high melting device, which can further purify the iron.

For Yan Xia, everything is on track.

…

One month later.

The number of robots increased by 4 more.

Yan Xia decided to expand the number of 3D printers. After all, the printing speed of one machine was too slow. It would be much faster to print parts using multiple lines.

"Ella, calculate how many 3D printers our plan requires, so as not to waste resources and time."

Ella entered into the calculation and got the result quickly.

"In severe summer, we need a total of 4,349 3D printers, not only for mining robot manufacturing, but also for printing other mechanical equipment."

"The first thing we need to make is photovoltaic panels so we can have a large supply of energy."

“And then you have to produce the furnaces to smelt the metal and make the alloys.”

"High-precision machine tools will be needed later. The accuracy requirements of 3D printers are not enough for the controllable nuclear fusion equipment we want to realize in the future."

"besides……"

"Stop, stop, stop!"

Yan Xia originally thought this was a very simple matter, but once she explained it, she found that it was not the case at all.

He quickly stopped Ella.

"As a mature AI, you can save these plans and do it later. There is no need to explain it to me."

"On this basis, the manufacturing of resuscitable cryogenic chambers must be added in the early stage. This must be manufactured first."

Follow these plans from Ella.

It is estimated that it will not be completed within a few decades.

If he keeps waiting, he will either go crazy or die.

As the last human being, he couldn't just give up without achieving his first goal.

"No problem, Yan Xia!"

Ella's automatically generated plans are implemented as quickly as possible.

It's just that this is the fastest.

It also took half a year.

The number of robots exceeded 100, and the number of 3D printers expanded to 20. After that, they were all invested in manufacturing photovoltaic panels.

After the completion of a 5,000 square meter photovoltaic panel array, the first asteroid factory was also completed.

Due to the use of improved new photovoltaic panels, the power of 5,000 square photovoltaic panels can reach 1,300 kilowatts, and because it is in the universe, the energy loss is lower and the power generation efficiency is higher than on the ground.

Including losses, the daily power generation capacity of the completed photovoltaic panels reached 28,800 kilowatt hours.

After all, it is space, there is no need to consider weather factors, and power generation continues 24 hours a day.

This is enough for the factory to use.

As Yan Xia himself expected, nothing can be achieved overnight, but requires a lot of time.

Fortunately, once everything is on track, development will be fast.

100 robots turned into 1,000 robots, and 20 3D printers turned into 300. It only took four months.

The factory began to smelt a large amount of metal and began to make manual lathes.

Then robots were used to operate manual lathes to produce parts with high enough precision and complete the manufacture of high-precision machine tools.

…

Until another year and a half passed.

After the number of high-precision machine tools exceeded 10, other machines were really started.

Ella first made a dormant cryostat according to Yan Xia's requirements.

This technology is extremely difficult. First, ultra-low temperature must be achieved, and then liquid nitrogen must be used for freezing.

Before dormancy, a special anti-coagulant must be injected into the human body to prevent the blood from freezing and the water in the body from condensing into ice crystals.

Only with these series of technologies can the dormant cryostat be initially realized.

This technology has not yet been realized on Earth. Yan Xia has to use the technology calculated by Ella alone.

He has no choice. He can't be a computer engineer who has to rub the technology tree by hand, right?

…

Another two and a half years have passed.

The factory on the planet has become an industrial park.

This is already very fast.

Even with the support of the mature industrial system on Earth, it is quite explosive to build an industrial park from scratch on the ground in just four years.

But for Yan Xia, it is too long and a little scary.

Fortunately.

Everything finally came to an end.

In 2044 AD, nearly 7 years after the destruction of the Earth.

Ella reminded him.

"Yan Xia, the hibernation cryochamber you need has been made..."
