Deep in the vast space, a red dwarf star floats quietly.

Its mass is only 0.25 times that of the sun, and its radius is only 0.3 times that of the sun.

Red dwarfs of this mass can be found everywhere in the Milky Way. According to Han Yang's statistics, among the approximately 3000 billion stars in the Milky Way, red dwarfs account for about 80%.

There are only two planets surrounding this red dwarf star. A massive gas giant with a mass about seven times that of Jupiter orbits it only 7 million kilometers away.

Because the distance is too close, the gas giant planet has been locked by the gravity of the red dwarf star, and can only face it with one side forever, forever enduring the heat of the star.

Its backside can only remain cold and dark forever.

One side is cold and the other side is hot, creating strong atmospheric convection. On it, supersonic winds can be seen everywhere. Powerful thunderstorms and acid rain occur year-round.

About 1.6 million kilometers away from the red dwarf, a rocky planet with a mass of about 1.1 times that of Mars revolves around it in an extremely elliptical orbit.

Judging from the orbital composition data and elemental composition data, this planet does not look like it was formed in this star system, but more like a rogue planet that accidentally broke into its territory and was captured by its gravity.

At the same time, the aphelion of the rocky planet is gradually increasing due to the existence of the gas giant planet. It is calculated that in about 200 million years, the planet will finally break away from the gravitational pull of the red dwarf star and enter the vast starry sky again, embarking on a heroic journey of interstellar wandering.

This situation is actually quite common in the Milky Way. In binary stars or multi-star systems, there are often unlucky planets that are thrown out during the gravitational battle. After wandering for tens of millions of hundreds of millions of years, they are captured by another star. After a few more years, he will leave again.

On such a wandering planet, where no life exists, a huge construction operation is going on quietly.

Factories are roaring underground, with hundreds of millions of robots and more intelligent machines busy all day long. The anti-gravity speed car shuttles non-stop on the underground orbit all day long. Huge energy that is comparable to the radiation power of low-mass stars is emitted through numerous quark fission power stations and extends to every corner of the planet along the extensive energy transmission network, supporting this huge base operation.

Millions of factories produced all kinds of supplies.

Wheat, barley, rice, rye, corn, sugar cane, starch, sugar, leather, rubber, as well as various energy blocks, metal products, lubricants, parts, cables, electronic devices...

Its categories total tens of millions.

These tens of millions of supplies passed through different channels and finally converged into various distribution centers.

There are thousands of specially built large supply box production centers that continuously produce countless metal boxes and supply them to the distribution center.

When the boxes and various supplies arrive, the robots in the distribution center will be busy packing the supplies into boxes according to different types, volumes, qualities, uses, etc.

After being packed, they will be transported to a large transport ship moored nearby.

One transport ship can carry 100,000 of these metal boxes, with a total transportation mass of millions of tons.

Afterwards, with the help of anti-gravity technology, these heavy transport ships will take off directly from the surface of the planet, enter the vast space, and transport them to a place about two trillion kilometers away from the star, and then give them the appropriate course and speed, allowing them to slowly drift into the deeper depths of the universe.

There are more than 20,000 such heavy transport ships in this galaxy.

On average, it only takes about a year for a heavy transport ship to complete a round trip. This means that on average, about 58 spacecrafts come to the drop point every day, and an average of about 2.4 spacecrafts per hour.

The drop point is fixed, and each heavy transport ship will come to the drop point to unload the boxes it transports. At the same time, the direction and speed of the dropped box are also fixed.

This created such a magical scene: these cargo spacecraft were like waterwheels, and the unloaded boxes were water.

Starting from the drop point, a river of metal boxes was created in the vast icy starry sky.

This river flows slowly, advancing at a speed of about 50 kilometers per second. The total length has now reached 160 billion kilometers, of which the number of boxes has reached more than 200 billion, and it is still getting longer.

Time passed slowly, and more than ten years passed in the blink of an eye. By this time, the length of the river composed of metal boxes had reached 350 billion kilometers, and the total number of boxes was close to 500 billion.

At this moment, dozens of light-years away from this galaxy, a certain star flickered very quickly, and then everything went as usual.

At the same time, all construction on the planet inside the galaxy stopped at the same time. Several large-yield quark fission bombs detonated, and the blazing fire and huge energy destroyed everything instantly.

More than 20,000 heavy transport ships and many other interstellar vehicles simultaneously changed their course like moths flying into a flame, heading straight towards the red dwarf star, burying themselves in the star's light without leaving any trace. .

Except for the remnants of the explosion and the tens of billions of metal boxes still drifting in space, there is no sign of anyone's arrival in this galaxy.

Those tens of billions of metal boxes were simply abandoned, and no one cared about them anymore.

for the fleet which was supposed to receive them did not come.

To meet their fate, they will drift in the vast space at a speed of about 50 kilometers per second for endless time in the future.

In the future, it may break into a certain star system and be captured by the star's gravity, or it may directly hit a planet and turn into dust.

But the greater possibility is that in the long time of hundreds of millions and billions of years, not even a planet will be encountered, and eventually under the influence of interstellar dust clouds and interstellar radiation, it will slowly disintegrate and eventually merge into Go into the universe and become a part of the interstellar dust cloud.

There is no way, the universe is too empty. For such an aimless flight, the probability of getting close to a certain planet, not to mention collision, is too low.

Scenes similar to this star system are repeated in a total of nine star systems with a radius of 1000 light years with it as the core. The hundreds of billions of metal boxes that Han Yang produced using his computing power were directly discarded.

Only one system produces supplies that are not wasted.

At the beginning, in addition to the supply star systems prepared for Luotu civilization, Han Yang prepared not one, but ten supply star systems for the human fleet.

A total of ten galaxies launched ultra-large-scale industrial production at the same time. Each galaxy has a complete range of industries and can produce all types of tens of millions of supplies needed by the human fleet, and in sufficient quantities. Each supply system has the ability to supply the human fleet on its own.

When setting off, even Han Yang himself didn't know which star system he would ultimately choose to produce supplies. Only when he is really close will Han Yang make a temporary decision.

Even if there are outside snooping forces, they will only find one or two supply galaxies at most. Amazing discovery of three or four.

Even if you find five and add tracking devices to the supplies in these five galaxies to try to track them, then if I randomly select one of the supplies in ten galaxies in total, there is a probability of up to half that it will not work. You will be tracked.

In this way, the possibility of exposure is minimized.

At this moment, the human fleet has sailed to the edge of the selected star system and arrived next to the long metal river composed of metal boxes.

Thousands of large space carriers have all broken away from super-light navigation and are floating quietly in space. High-performance detection equipment extends to trillions of kilometers away.

Once anything happens, these aerospace carriers will immediately enter a state of super-light navigation and start escaping again.

A large number of engineering transport ships have begun salvage. As a result, countless metal boxes and the supplies stored inside them fell like drizzle into every space carrier.

The already empty fuel tank was once again filled with various fuel elements;
Old and barely functioning parts were all replaced;
The mottled armor was removed and directly refurbished, and replaced with smooth new armor;
Due to the lack of energy and materials, the planting, breeding and aquatic product bases that had been idle for hundreds of years have also started to operate again. A large amount of fruits, vegetables, rice, flour, grains and oils, meat, fish, fungi, etc. have once again filled the food warehouse. Ready for those who must stay awake to keep the fleet running.

Just like a tired and dusty long-distance traveler who finally came to a well-equipped hotel, took a good bath, ate, slept, and changed into new clothes, his spirit was renewed and his fighting spirit was renewed. High-spirited.

The necessity of building a supply system in advance and preparing supplies was clearly revealed at this moment.

After the human fleet has gone through such a long journey, and the journey was so hurried at first, and it did not carry much supplies at all, and was traveling completely lightly, even with the presence of Han Yang, the human fleet could not wait for Han Yang to slowly build a base. , slowly producing supplies.

Once supplies are insufficient, catastrophic consequences will immediately occur. At least several billion people died in hibernation, and as many as hundreds of billions of people died.

If it were other civilizations that had to wake up the population one by one and rely on intelligent life to slowly build bases and slowly produce materials, it would be even more impossible to succeed.

They don’t even have basic supplies, and intelligent life can’t even survive. How can they build a base?

Once we fall into this situation, civilization will immediately die.

This is the risk of embarking on a large-scale interstellar voyage while traveling light and simple.

It can be said that if humans had not built a supply galaxy in advance, it would have been impossible for the Luotu civilization to complete the feat of escaping from the Silver Alliance.

At this moment, the supply galaxy for Luotu civilization has completed its mission.

All bases in the supply system have self-destructed, completely destroyed.

The supplies placed at the edge of the galaxy in advance have been taken away, and the Rotu fleet has embarked on a voyage again, going to places unknown to humans, just like the Rotu civilization does not know the course of the human fleet at this moment.

That's fine, keeping distance is the best choice for both parties. If anything happens, just communicate directly through long-distance communication.

After completing supplies in this galaxy, Han Yang once again destroyed the corpses and traces, and then controlled the huge human fleet to enter the super-light navigation state again, heading towards the edge of the Milky Way at eight times the speed of light, which is also the direction of the Canis Major dwarf galaxy. , embarked on a long voyage again.

This time, due to sufficient supplies, the human fleet sailed for another five hundred years and sailed a distance of 4000 light-years, but there was still a lot of supplies left.

On this day, the human fleet once again broke away from the super-light speed of navigation and hid in a place 3 light-years away from the nearest star.

After that, an engineering fleet set off and continued to sail towards the star system at super-light speed. When it was about 1.6 trillion kilometers away from the star, it switched to regular sailing and continued to approach.

This is a binary star system. A blue giant star and a white subgiant rotate around each other, and violent radiation sweeps across the entire star system, scorching the three poor planets in the galaxy.

In this desolate and harsh place, huge construction was once again launched under the direct control of Han Yang.

Because the fifth-level civilization-level space carrier has been abandoned by Han Yang, the construction cannot be carried out in advance this time. The construction can only be carried out when the human fleet arrives at this moment and the engineering force arrives.

Han Yang has been waiting here for three hundred years.

Over the past three hundred years, the surfaces of the three planets and some satellites have remained the same as before, but their interiors have changed drastically. A total of millions of large factories roared day and night, not only producing supplies for subsequent voyages, but also producing up to a million brand-new spaceships that had never been produced before.

Large residential spacecraft.

It is a residential spaceship, not a passenger ship in the conventional sense.

Passenger ships are only for passengers to ride on for a short period of time, and they will not live on them for a long time. Large residential spacecraft are of course different.

They are real places for people to live. They must not only have the life-support systems and living spaces found on passenger ships, but also must have municipal facilities such as parks, roads, grasslands, and playgrounds, as well as schools, hospitals, shopping malls, and other places, and they must also have their own Planting, breeding, aquatic products base, etc.

A large residential spaceship is a human city with a complete ecology.

Such a large residential spacecraft is 20 kilometers in length, about 6 kilometers in width, and 4 kilometers in height. The overall internal plan is divided into 40 floors, with the height of one floor being 100 meters.

In this way, a large residential spacecraft has a total internal area of ​​approximately 4800 square kilometers. In addition to the space occupied by the spacecraft facilities, there are still about 3000 square kilometers left, which can support about 100 million people to live and work comfortably and comfortably.

As for such huge spaceships, Han Yang built a total of one million. (End of chapter)
