With the participation of two new advanced artificial intelligence quantum computers, Yingqi and Qiming, the construction speed of planetary engines has been qualitatively improved.

In particular, the twenty engines on the moon were the first to be built.

In the African savannah, the afterglow of the setting sun gilds the wild African land with a layer of gold.

Lin Xu was wearing a power exoskeleton armor that wrapped his whole body, sitting in a group of lions, stretching out his hand to pet a male lion like a cat.

The lion was held down by the palm of Lin Xu's exoskeleton armor, even if it was reluctant, there was no other way.

It's like a wild cat can't resist humans.

The lion could not resist a human who had worn the armor of the powered exoskeleton.

Especially after it tried to bite Lin Xu's arm, but in the end it lost two teeth, and it was immediately as good as it could be.

And Lin Xu, who fulfilled his wish to play a lion, also showed a satisfied smile on his face under the helmet.

In the RV on the maglev traction platform not far away, Miss Qiu walked slowly towards Lin Xu's location.

With silver hair and a shawl, she wears a professional suit, and she looks like an ordinary white-collar beauty, nothing special except for her pretty.

The lions that surrounded Lin Xu and were helpless against Lin Xu immediately became restless again.

One of the lions roared and pounced on Miss Qiu, who seemed to be extremely delicate.

saw that Miss Qiu just waved her hand indifferently, as if driving away a fly, and this palm happened to hit the jaw junction of the lion that pounced.

With a bang, the lion was slapped on the ground entirely, with a whimpering sound coming out of his mouth, and he struggled for a long time and did not get up.

Looking at the chin again, it is a complete dislocation.

Not far away, a robot took the initiative to step forward to help the dislocated lion heal, and the lions were honest and well, and no one dared to provoke Miss Qiu.

"Master, the dormancy chamber is ready, you should be ready to sleep." Miss Qiu reminded.

"Wait, let me last look at the moon." Lin Xu looked up at the sky, and patted the lion's ass with his palm.

In the past, when he and his ex-girlfriend were still together, the two of them had a raccoon cat named Goudan in their small home, and Goudan liked Lin Xu to pat his ass the most.

As long as you pat your buttocks, the dog, which was originally very cold, will immediately collapse into a ball, and make a purring sound in your throat.

Whenever this happens, the ex-girlfriend will jealously catch the dog and ask why it only kisses his father and not his mother.

It's a pity that Lin Xu was diagnosed with terminal cancer, and after his ex-girlfriend cried in front of his hospital bed, he moved out of the two's home with the dog egg and disappeared.

When night falls, the starry sky on the African savannah is bright and magnificent, and the moon is exceptionally bright.

Not surprisingly, this should be visible from Earth, the last normal Full Moon, and soon the Moon will be pushed out of orbit and headed for Mars.

From then on, there will never be such a bright full moon on Earth again, and the moon will get farther and smaller over time until the moon is far enough away that it can no longer be seen.

"Human Lin Xu, are you going to personally order the fire?" Taiyin's voice came.

Compared with Miss Qiu and Yingfu, who also have advanced artificial intelligence, but still perform wooden, Qiming and Taiyin, a higher artificial intelligence that has existed for tens of thousands of years, obviously have the feeling of intelligent creatures.

At least at this time, it could detect Lin Xu's emotional side, and then make an inquiry.

"Are you ready?" Lin Xu asked.

"Ready."

"Ready, master."

Taiyin, Yingfu and Qiming, three voices came at the same time.

Lin Xu, who was wearing a power exoskeleton, took a glass of wine handed over by Miss Qiu, raised a glass to the moon, and then opened a gap in the mask, drank it in one gulp, and then ordered.

"Let's light the fire."

In an instant, Lin Xu, who was located on the African savannah, saw more than a dozen subtle pillars of light light light on the moon in the sky.

The pillar of light seemed faint, but it was eternal.

Everything had already begun, and although the moon didn't seem to have changed much now, Lin Xu knew that in a few days, the moon would get smaller and smaller until it was no longer visible.

At the same time, because of the departure of the moon, the entire ecological circle above the earth will also be wiped out.

The first is that the tides are less frequent, and a large number of marine life that depends on the rise and fall of the tide will become extinct.

Then the Earth's magnetic field will change, and migratory birds will not be able to find their way based on the magnetic field to find food.

The weather can also become unpredictable, with the North and South poles melting and the rainforests drying up.

The main thing is that the rotation of the earth will also increase, and the time of day will be significantly shortened.

All this is naturally nothing to the earth itself, but it is a catastrophe for the life that lives on the surface of the earth.

"Include them in the African Biosphere Project." Lin Xu scratched the lion's chin like a cat and said.

"Yes, master." Ms. Qiu, who is in charge of the ecosphere project, replied.

The so-called ecosphere plan is that Lin Xu is preparing to build several ecospheres that simulate various environments on the earth.

There are African biospheres, Asian biospheres, American biospheres, desert biospheres, rainforest biospheres, marine biospheres, and many more.

Some of these biospheres will be built underground on the planetary engines, and the thermal energy of the planetary engines will be used to keep the biosphere running.

The other part is built on the original location of the ground, with ecological dome technology and a nuclear fusion sun, simulating the normal sky.

Although all the animals and plants on the entire earth already have genetic backups, Lin Xu still feels that it is necessary to preserve some ecosystems.

Even if it is a place to relax and unwind occasionally during future space voyages, it is also good.

After all, in astronautics, mindset is very important.

The existence of these ecosystems that maintain the original appearance of the earth is very beneficial for regulating the body and mind.

After arranging everything, Lin Xu finally let go of the lions and let them leave.

After a mechanical click, the power exoskeleton opened, and Lin Xu walked out of it.

Miss Qiu next to her had already set up a barbecue grill and grilled two large pieces of fresh beef.

Speaking of which, this was still the prey of the lions just now, but now it has returned to Lin Xu.

Of course, Lin Xu couldn't eat the whole bison, so Miss Qiu just cut two pieces of the best meat, and the whole bison was still taken away by the lions.

"Where is the dormant chamber?"

"The Sky Dome space station."

"Twenty years, when I wake up in twenty years, the earth will be a different place." Lin Xu sighed.

"Yes." Miss Qiu replied with a straight look, and the movements of cooking roast beef in her hands did not stop.

It wasn't until an hour later that an airplane rose from the African savannah and sped away toward low-earth orbit.

There, the Sky Dome space station, is already on standby.
