The interstellar voyage has entered the countdown.

Shortly after collecting the corpses of the space beast, in order to make up for the resources consumed by the mother ship during this period before departure, the first asteroid mining finally began.

An asteroid not far away became the target this time.

This asteroid is quite large, with a widest place about six kilometers and a narrowest place of three kilometers. The surface is covered with ice and snow. Because it is close to the sun, it pulls a tail of hundreds of kilometers long, which looks spectacular.

Fortunately, during the detection, the thickness of ice and snow on its surface is not large, only a few dozen meters thick, and there are a large number of iron meteorites inside, and contain a large number of other elements.

Humans do not consume much water resources, but metals consume the most. This mining mainly collects metals, and a meteorite like this is enough to supplement all inventory.

Hundreds of engineering robots, loaded with a large number of materials and tools, began to land on the asteroids. In the next time, they will clear ice and snow on the asteroids, level the ground, and build simple power plants and lay lines.

In addition, on the side of the asteroid, they will also install three engines so that they do not float too far.

The entire three-way project took less than a week.

Immediately afterwards, the second batch of engineering robots pushed modular factories like giant containers toward space. The flames of plasma gushing from time to time behind the robots kept spewing, gradually landing on meteorites like fireflies.

The modular factory slowly floats down according to the designed position, the concealed buckles arranged on the ground and the bottom of the factory are locked seamlessly, and the factory is gradually unfolding.

These are real unmanned factories, with no extra lights and no well-connected channels. A large number of metal smelting equipment with complex structures, with large metal smelting equipment crowded into a pile, making all the space fully utilized.

Not long after it was spread out, a huge metal pipe with a diameter of nearly thirty meters slowly rose like a giant beast awakening. Its pipe opening was straight at a piece of open space not far away. The next moment, a terrifying magnetic field emanated from the pipeline.

Soon the ground began to soften like a liquid, and it continued to extend downward while absorbing the substance.

The reason why this metal pipe is so large is because it is telescopic and has hundreds of layers of metal pipes nested inside. According to the design, it can fully penetrate five kilometers underground and absorb minerals.

Asteroid mining has become quite mature in the glass star civilization and has a complete set of procedures. Although it is only the first time for humans to inherit and absorb this technology, everything is orderly and familiar with it.

...

It will be April 2020 soon, and humans have been docking in space for four years.

All the preparations for the long-distance voyage have been completed. For safety reasons, even the countless ravines and ravines on the outer armor of the mother ship have been rested, making the entire spaceship brighter and new. Even the parts that are far from scrapped and have been used for a certain period of time have been replaced.

Over the past month, countless spacecraft maintenance engineers holding various detection instruments have repeatedly detected every corner to discover possible hidden dangers.

...

Before we knew it, the originally stable and peaceful social atmosphere became tense and depressed.

Although a large number of news media are repeatedly publicizing and inspiring every day, over time, everyone's face becomes more and more anxious and uneasy.

Even Luo Yuan often feels confused in his heart.

After all, this is an adventure with an unknown future. Maybe it is a long march for humans to create a glorious future, or maybe it is a path of no return for humans, but no matter how he is wandering, the time for departure is still approaching day by day.

The route to Xinglu has been determined long ago.

The Barnard star system, located about 6 light years on Earth, is the target of this time. The reason why I chose this star is that it is because it is relatively close. The first long voyage is too far away, which is too risky for humans and is too risky.

On the other hand, it is because it emits the weakest light. This is a red dwarf, which belongs to the ancient star in his later years. It emits a faint dark red light and is a good hidden place.

In fact, since the distance between two civilizations is completely astronomical, it is not as easy to detect each other as expected. No matter how advanced the detection system or the efficient computer is, they are powerless in the face of the vast starry sky.

Moreover, because the distance between them is far, the light-year calculation is performed.

One light-year distance, that is, the distance when light flies for one year. For example, the glass star is 28 light-years away from the earth. It takes 28 years for the light it emits to transmit to the solar system, which means that the images of glass star obtained by humans are completely historical pictures 28 years ago.

And the same is true in turn.

It is less than five years since the annihilation of the Bosco advance troops, which means that at least in the next 23 years, human actions will be completely invisible unless the other party has developed super-light speed detection capabilities that do not rely on light, or the battleship's flight speed exceeds the speed of light.

No matter how the former hides, the human target has been locked, while the latter is slightly better and at least has some invisibility time.

But this is just the worst case!

Generally speaking, as long as its detection system still relies on light, the weaker the area, the lower the chance of being discovered. For example, the vast black domain between stars, if you want to find a spacecraft, the low probability is completely negligible, but humans cannot hide in the dark domain forever. It is a zone close to an absolute vacuum and almost no material replenishment can be obtained.

Perhaps they can "save money" like a mouse and hide for decades, but they pay at the price of limiting human development.

In the past six months, a total of 240,000 newborns have been born in humans, of which 50,000 are produced by the parent body, and the remaining 190,000 are produced by laboratories. At this growth rate, the number of humans will double in more than ten years, and the spacecraft will become more crowded and cannot accommodate more people.

Therefore, humans must find a new star system to live temporarily.

According to the detection of the mother ship, there are rocky planets and gaseous planets in the Barnard star system. Whether it is a rest and recuperation place that is supplemented by resources or a permanent development, it is quite suitable and is completely an advance or retreat position.

As for the harsh and cruel bad situation there, it is completely worth mentioning for humans who have already entered the interstellar civilization.

As long as you give enough time, with the current technological strength of human beings, you can completely transform a planet, but it is just high and low efficiency.

"Mayor, the good news from the Antimatter Laboratory is here!" At this time, Secretary Chen Xinjie pushed the door open with a happy expression.

"Oh!" Luo Yuan took the document and flirted with a few pages. His originally frown brow suddenly stretched slightly: "The energy conversion rate has reached three million to one!"

In fact, the first antimatter experimental preparation factory has been built for half a year, but since the technology has not yet been fully mature and the safety is not fully guaranteed, it has been in a technical verification state.

Even production is a production within the safe dosage range. After all, this is a spacecraft. Once an accident occurs, it will be enough to cause serious consequences and damage.

"It's a pity that this kind of thing is too dangerous and cannot be produced in the spacecraft, so it can only be used as a technical reserve." Luo Yuan then said to Chen Xinjie: "Send a commendation announcement to let their laboratory continue to work hard!"

"Okay, mayor!"

Chen Xinjie left quickly, Luo Yuan picked up the information again and looked through it, full of joy.

Don’t look at the energy conversion rate of only 3 million to one. In fact, when reaching this ratio, large-scale antimatter production has basically matured. With the energy production efficiency of nuclear fusion furnaces, one ton of antimatter can be produced by basically six million to ten million tons of pure water.
