Frozen in the ice and snow, the Great Wall is alongside.

Lin Xu was wearing power armor, lying on a recliner placed on the wall of the Great Wall, looking up at the sky.

Without the plasma blue light jet from the planetary engine pointing straight to the sky, the earth's sky at this time is becoming quieter and quieter.

The dark starry sky is dotted with dense stars, forming a shining Milky Way.

It looks no different from the starry sky of the Earth in the past, except that because the Earth has lost its atmosphere, the light of the stars cannot be refracted, and the stars cannot twinkle.

At the same time, because of the loss of light pollution, the starry sky looks clearer.

At this time, the Earth has long been far away from Proxima Centauri and is traveling in the universe at one-twentieth of the speed of light.

And with more and more planetary engines installed with curvature engines, each curvature engine starts, and this speed is still increasing little by little.

And the direction in which the earth is heading at this time is the direction that the human voyage group has been going since the white star set sail again.

According to the information in the White Star Database, the target of the human voyage group 10,000 years ago was another galaxy 180 light-years away from Proxima Centauri.

Because according to human observations and calculations at the time, it was also a galaxy with terrestrial planets.

So humans used it as their next stop.

So Lin Xu followed in the footsteps of human beings, and naturally he also wanted to take a look.

At the very least, we have to find the human race, the next course.

The curvature engines on the 100,000-seat planetary engines are expected to be fully installed in ten years.

At that time, the speed of the Earth will also be twice the speed of light.

In other words, in about 100 years, Earth will reach the target galaxy.

Discover the next step in humanity's footsteps.

"Master, it's time for you to sleep." Miss Qiu appeared behind Lin Xu and reminded.

That's right, Lin Xu is going to sleep again.

This time it's a 100-year hibernation, and if nothing happens, you'll be able to reach your target system when you wake up.

"Wait a minute, let me see it for a while." Lin Xu looked at the starlight in the sky and sighed, "It's a pity, there is no blue sky!" ”

"If you want to see the blue sky, you can just go under the ecological dome and see it." Miss Qiu came up with an idea.

"That's not really a blue sky, unless the ecological dome covers the whole earth, the sky is fake." Lin Xu sighed.

Immediately, Lin Xu was suddenly stunned.

Since there is no longer a need for planetary engines to carry out plasma injection and accelerate the earth, if we can build a huge enough ecological dome to encompass the entire earth, will it be possible to restore the ecology of the entire earth and restore the earth to its former appearance?

It couldn't be done before because the planetary engine needs to inject plasma to accelerate the earth, so it can't be wrapped at all.

However, the curvature engine accelerates the earth, using the space curvature bubble technology, which directly distorts the space around the earth to achieve the purpose of making the earth move.

So even if the whole earth is wrapped, it will not affect the operation of the curvature engine inside.

Because the power of the curvature engine acts directly on space, it will not affect any object on the earth's surface, even the huge ecological dome that envelops the world.

It seems to be really possible.

It's just that it must be a huge project.

But it doesn't matter, anyway, the autonomous machine is idle, after the completion of the construction of the curvature engine factory and the anti-gravity factory, and the installation of the curvature engine of 100,000 planetary engines.

It is completely possible for them to start building an ecological dome covering the entire earth, and they can build it whenever they want, and they will be idle anyway.

So as soon as he thought of it, Lin Xu immediately summoned seven intelligent quantum computers and began to calculate the feasibility of doing so.

The end result is gratifying, and theoretically feasible.

After the planetary engine does not need to inject plasma to accelerate the earth, the entire earth is wrapped in an ecological dome, which will not affect the normal operation of the curvature engine on the earth's surface at all.

It's just that it takes a little longer to build such an ecological dome that encompasses the entire earth.

It may take hundreds of thousands of years to build, after all, it is necessary to wrap the entire earth, and the amount of work is too huge.

The amount of work to build 100,000 planetary engines at the beginning is simply a younger brother compared to this.

If the earth is analogous to a large watermelon, then building a planetary engine on the earth is, at most, a few sesame seeds on the surface of the watermelon.

But now it's about wrapping the whole watermelon in it.

The amount of work has increased by a hundredfold.

But what Lin Xu has is time.

Again, the self-discipline machine is idle anyway.

I thought that I didn't need to wait for the Earth to return to the solar system to see the blue sky again, with flowers hanging from the branches.

Lin Xu couldn't stop getting excited.

So in order to discuss with the intelligent quantum computers about wrapping the entire earth in the ecological dome, Lin Xu's dormancy time was postponed for a few days.

The entire plan was finalized and was named by the Dome of the Earth project.

The Earth Dome project first aims to build a million pillars to support the entire Earth's sky.

Each pillar needs to be 100,000 meters high, that is, 100 kilometers, and the height is nearly ten times that of a planetary engine, making it much more difficult to build than a planetary engine.

Then, with the celestial pillar as a node, an ecological dome covering the entire earth is built.

You must know that in the 21st century, the altitude of the Tiangong space station from the ground is only 340 kilometers.

It can be said that at that time, the height of the entire earth's dome of 100 kilometers has already enclosed the troposphere, stratosphere, mesosphere, and part of the thermosphere of the earth's atmosphere, and only the fugitive layer is not included.

Once built, the Earth's atmosphere can be restored to its former appearance under artificial adjustment.

At the same time, it is necessary to lay out the orbit of the artificial sun and the orbit of the artificial moon in the sky.

Let the sun and moon also return to the same operation as before.

The whole project is expected to take thousands of years, and possibly even longer.

But just thinking about the scene after the plan was completed, Lin Xu couldn't help but laugh.

Finally, the plan was finalized, and only ten years later, after the autonomic machinery had completed the installation of all 100,000 planetary engines, and had also completed the anti-gravity modification of each other, the Earth Dome project could begin.

So Lin Xu entered the dormant warehouse with a beautiful vision and began a hundred years of dormancy.

By the time his dormancy was over, the Earth Dome project had only been partially completed.

Lin Xu still can't wait to see what the plan will look like when it really starts to be implemented.
