In a minimalist cosmic void, Hua Kejing floats like a ghost.

Of course he didn't hang,

There is no ascension,

Didn't dream anymore.

In fact, this is just a model of the solar system simulated by Xiaole.

Due to the limited computing power, the details of the entire star system cannot be fully realized, so there is only a powerful light source and gravitational source in the infinite distance behind the Hua Ke mirror.

That's a sun.

and the blue earth under our feet, which is only in vain and lacks brilliance.

But if it's just for space experiments, it's enough to have all this.

……

"Little music."

"I'm here."

"It's time to start showing."

As soon as the voice of Hua Kejing fell, a bright spot suddenly appeared on the outer orbit of the earth.

As the field of view quickly closes, the bright spots quickly grow larger at a terrifying rate.

What is that?

It is a space city with a multi-ring structure!

Suddenly, the space fortress had been pulled by the earth's gravity and flew in front of Hua Kejing.

The behemoth was on the side, and Hua Kejing looked away from afar.

This space city with multiple rings is indeed huge, but compared with the space fortress that appeared in Jupiter's orbit in Xiaole's computational model a long time ago, it is far from the actual scale and visual impact.

Hua Kejing still remembers that the name of the space city in Jupiter's orbit is Himalayas, which is a giant artificial sphere composed of six huge and spectacular metal rings with a diameter of more than tens of kilometers.

But the structure that now surrounds Earth's orbit is much simpler.

Although it is also a man-made gravity structure in the shape of a partial ring, it is two coaxial rings.

This is a great degree less technological than the Himalayan Space City, and it looks more like a giant roller from a distance.

Brush - Brush - Brush -

The gaze gradually narrowed, and this space city was already approaching.

Hua Kejing's body seems to be pulled by a smart force to fly and shuttle through the space city.

The central axis of the space city is an independent space passage that runs through it, which is also the spaceport of the entire city.

Small spacecraft, or shuttles, can dock and connect through the central axis section, and then transfer to other vehicles to enter the space city.

Next, Hua Kejing looked at the interior of the space city, and browsed the unique lighting system, ecological circulation system, including the nuclear power supply and nuclear power propulsion system that occupy one-fifth of the space at the end of the city.

……

Leaving the space city, I returned to the exquisite two-storey cabin in the virtual world.

Hua Kejing asked the artificial intelligence Xiaole: "Does this city have a name?" ”

"You can pick up one for yourself."

"Hmmm......"

After thinking about it for a long time, Hua Kejing decided on a rather reflective name - the capital of the galaxy.

"How about it, is the name Galaxy Capital okay?" Hua Kejing asked.

"Yes."

Hua Kejing also asked casually, every time it comes to such a time, Xiaole is an emotionless "can" robot.

"What is the orbital altitude of the Galaxy Capital?"

"You can make arguments and adjustments according to the actual situation."

Hua Kejing: "......"

Hua Kejing has a headache, and this question is really critical.

Because the height of the orbit around the space city is closely related to many important issues during construction.

For example, the Loch limit (the shortest distance for two celestial bodies to maintain a smooth motion - calculated by Edward Loch).

When a large celestial body is close to a certain limit from its satellites (not artificial satellites, but moons like the Moon), the pulling force and tidal force generated by the gravitational pull of the celestial body will break the satellite, the satellite will disintegrate, and the debris will rush towards the large celestial body, fall on the surface of the celestial body, or become the ring of the celestial body, just like the rings of Jupiter and Saturn.

PS: Jupiter's rings and Saturn's rings are made up of countless small pieces of ice, small rocks, dust, and so on.

In conventional understanding, artificial celestial bodies such as artificial satellites, small spacecraft or space station bodies, because of their small volume, small mass, dense structure, gravitational force cannot reach the effect of the Loch limit, so it is impossible for the earth's gravity to tear these artificial celestial bodies.

Normally, only large, low-density objects with a distance of less than the Loch limit will be torn apart.

Therefore, when the space city reaches a certain scale, its large volume and low density will become the focus of the Loch limit.

This means that the final orbit of the Galactic Capital must be set outside the corresponding Loch limit.

But then comes the problem of resource supply and construction radius.

It is conceivable that if the galactic capital is only built on the earth like a gourd, its cost must be the lowest, but this is obviously just a delusion and cannot be realized.

Then, with the increase of the orbital distance and the increase of the construction radius, the cost of each construction material and the delivery and launch of each component will also show a geometric progression.

In the end, Hua Kejing also has to take into account the acceleration problem of [Galaxy Capital].

Don't forget, in the entire space city construction plan, the Galaxy Capital will finally accelerate to the orbit of Jupiter.

This isn't like a normal spaceship.

No matter how unlicensed the Galaxy City is, it is also a metal city of astonishing size.

At what height the orbit accelerates, under what circumstances, and fuel consumption will be a matter of concern to the whole body.

To sum up the above, just like Xiaole said, Hua Kejing must make arguments and adjustments according to the actual situation.

……

Hua Kejing, who was thinking wildly, suddenly found that the text displayed on the mission interface had jumped.

He had just applied for the debut of Mission C016: the Lunar Resource Automated Acquisition Robot.

Now this situation should be a new phase of the task again.

Sure enough, Hua Kejing turned his head to look, only to see the screen displaying:

[Mission No. D001: Complete the construction plan of the space city Galaxy Capital.] 】

Achievement Progress: 0%.

Time limit: 2 months.

Rewards for completing missions:

Earn 3000 technical credits.

……

Well, the mission numbers all start with D.

This shows that after the tasks of the infrastructure era starting with A, the rocket and spacecraft development era tasks starting with B, and the lunar base construction era tasks starting with C, the new tasks of the D era have begun.

What kind of D era it will be, Hua Kejing still can't figure it out.

But he is well aware that the chicken thief's alien artificial intelligence requires him to complete the construction of the galaxy capital within five years.

It's a mission!

Even mission number D001: Completing the planning of the space city of Galaxy in 2 months is a huge challenge.

Not to mention the technical difficulties, I think that in order to smoothly implement the project of the construction of the lunar base, in order to deal with a lot of policy issues and international political issues, Hua Kejing was simply tortured to the core.

Hua Kejing complained as early as when it launched the three-step grand strategy.

Will this pace of construction be a little too fast?

Is building a space city in five years going to kill me?

What's more, with such a huge consumption of financial resources, if you are not careful, you will drag down all the industries that you have worked hard to build up under your jurisdiction, such as construction, aerospace, and health.

So, there must be some reason behind this!

In the past few years, Hua Kejing's doubts have always been with Xiaole's cautiousness.

Hua Kejing's puzzlement mainly focused on why Xiaole was almost crazy and demanding himself to speed up the pace towards the stars, and the reason behind this was really just to save Lu Ban?

Xiaole's cautiousness is reflected in the sharing of scientific and technological and basic theoretical knowledge, which is always intriguing.

It's like why do you want to use Hua Kejing's personal hand to influence the scientific and technological process of the whole world?

Why is it that they are going to build space cities, but they are unwilling to help mankind deconstruct the mystery of gravity and achieve a breakthrough in the theory of great unification.

PS: The unity of gravitational force, electromagnetic force, strong interaction force, weak interaction force

Think about it, if Hua Kejing wants to go to the core of the galaxy with a big roller, that is not a way.

If you want to rescue Luban as soon as possible, shouldn't you improve the scientific and technological level of human beings as soon as possible?

If you go step by step like this, even if Luban is not cold, Hua Kejing will be cold.

But that's what happened,

A man with a stomach full of problems,

A person who knows that you have a full stomach and doesn't say anything.

……

I salute every friend who has been with me all the way, thank you for your support!

[Hua Kejing's puzzlement, Xiaole's cautiousness] why the unification in 2030,
