After the launch of Dark Space's "Lunar Star Mineral Mining" program.

Since it accepts investment from the private sector, government or any source of capital, there is no upper limit on the amount of investment, and the amount of money invested in the investment is as much as it is likely.

As long as the relevant transport ships and mining vehicles are put into actual use, the corresponding investment can start to get returns.

As of August 2025.

A total of 18,620 transport ships and 1,390 mining vehicles were put into use by Dark Space.

It has absorbed nearly 300 billion yuan of investment.

However, the actual amount of funds activated is only a tiny fraction.

According to the "first come, first served" principle, there are still more than 10 trillion funds still waiting in line...... These funds, with the consent of investors, can be misappropriated in advance and pay one-ten-thousandth of a daily interest.

In addition, I found the central bank of Xia Guo and borrowed a full 10 trillion yuan in cash at an annual interest rate of 5%.

In this way, the hands of Dark Space Company have a sufficient cash flow of more than 20 trillion.

In addition, there are millions of tons of minerals mined from the moon star every day, and as long as the space factory is built, at least 60% of the materials will no longer need to be imported from Blue Mercury.

Once a relatively complete space industry system is established, after five years, it is even possible to completely get rid of dependence on Blue Mercury and basically achieve self-sufficiency.

And so for the rest of the day.

The "Space City" project has been significantly accelerated.

And it's accelerating!

As far as the electromagnetic catapult orbit at the foot of the Kunlun Mountain in Xia Guo is concerned, the frequency of the ejection of the 'scimitar-type' space shuttle in this sky orbit was about 50 sorties per day on average.

But in September it increased to 200 sorties per day.

In October, the frequency of use of the electromagnetic catapult track reached the upper limit of 300 sorties per day, which could not be increased.

Fortunately, the second space orbit with greater ejection power, more mature technology, and higher efficiency has been basically completed and will be put into use within two months, and the number of space shuttle sorties ejected every day can break through to more than 1,000 sorties and transport more materials into space.

Of course, compared with the ejection capacity of the electromagnetic track, it is actually a transportation boat equipped with power furnace energy that plays the role of the main transportation.

The upper limit of the high-orbit carrying capacity of the scimitar space shuttle is about 10 tons, and the 1,000 sorties launched per day are only about 10,000 tons of supplies.

And the maximum carrying capacity of the transport boat can reach 150 tons.

In the past few years, Liwei has taken out 100 high-power power furnaces, and let the relevant factories produce 100 low-profile version of the "traffic boats", plus the original five long-term space-to-earth round-trip transportation tasks, a total of 105 high-power traffic boats.

A single boat can perform up to two round-trip trips per day.

It is also possible to cooperate with dozens of traffic boats at the same time, using carbon fiber ropes to tie up large-scale factory components weighing thousands of tons and pull them into space.

It can transport up to 30,000 tons of equipment or materials to outer space in a single day, constantly contributing to "Space City".

A few months later.

December 2025.

Quantitative change leads to qualitative change, and 20,000 kilometers away in space, there is finally a behemoth that can be seen by human eyes even if it stands on the surface of Blue Mercury.

It consists of multiple parts.

The outermost part is 12 petal-like iron pot-shaped solar power plants facing the stars, like the twelve scales of a clock, evenly and equidistantly distributed, and at the same time, due to the existence of light pressure and solar wind, these twelve petal-like power generation factories can produce a pushback force, but this force is like a wind mill, which is cleverly used, and actually makes the space city rotate slowly through the connection structure of the outer ring.

Although the circular structure of the space city rotates very slowly, because its diameter is 50 kilometers long, even if the angular velocity is very slow, it can generate 0.5G centrifugal gravity in the "settlement zone" that looks like a straight lane with a width of 500 meters and a circumference of more than 157 kilometers.

Of course, on the longitudinal connecting axis in the center (like the axis of the center of a cylinder), there will certainly not be only one "settlement belt", and the first ring "settlement belt" is basically completed, and a full twelve parallel ring "settlement belts" will be built in the future.

Assuming that the settlement zone of each ring can accommodate 300,000 people.

Multiplied by twelve, it means that this space city can accommodate up to 3.6 million people to settle and settle.

And these are just purely civilian facilities.

Facilities such as the "vegetable factory" for growing vegetables will occupy two new loops on the central axis that extends outwards and will be used for agricultural production.

In addition, four ring roads with different angular velocities will be set aside to arrange light industrial production activities.

and a loop dedicated to storing water and purifying air.

The medical system and the urban management and control system should also occupy a ring road.

The outermost ring and the innermost ring of the space city should be equipped with a military defense system, occupying two ring roads at the head and tail.

A total of 24 loops have been properly arranged and utilized.

But the heavy industry system, as well as the future spaceyard, is not included.

Levi plans to build a space dock first (even if it is very simple), and then let intelligent industrial robots build multi-functional special heavy industry spaceships in the space dock, and put all the production tasks of heavy industry in the highly mobile industrial spaceship.

At present, a rudimentary space dock has been erected, and an industrial spaceship is under construction.

After the construction of the 10-million-ton industrial spacecraft equipped with nuclear fusion power is completed, and the most advanced 3D manufacturing technology is applied, it is estimated that more than 1 million industrial products can be produced, and the industrial dependence on Blue Mercury will be reduced to 50%.

About another ten years later.

The second generation of more advanced 100-million-ton industrial spacecraft has been manufactured, which can produce tens of millions of industrial products, including chips, display screens, and ion engines...... Even if the performance will be significantly worse, the industrial dependence on Blue Mercury will be further reduced to more than 20%.

And a few more decades later.

The third-generation advanced industrial spacecraft has been manufactured, and all the commodity needs of the space city are basically nothing on the ground, and they are completely self-sufficient.

So after some accelerated construction.

December 2025.

On this day,

Holding a telescope in his hand, he looked at the sky above him, and the giant white object that was slowly turning like a Ferris wheel had roughly taken shape.

In his heart, Levi engraved a countdown number of 300.

He muttered with a little excitement in his mouth:

"Let people decorate the 'first settlement belt' and build a few beautiful and comfortable houses, and within 300 days at most, I will live in that high sky, and be looked up to by countless people every day."
