"You're hibernating, too?" Although Chu Tianjiang knew that the figure was not Zhang Xiaogang, he had already adapted to this way of dialogue.

The program is quite intelligent and has a strong autonomy. If you don't consider other factors, you can indeed think of this program as Zhang Xiaogang's doppelganger. In a sense, it has all of Zhang Xiaogang's memories and some of Zhang Xiaogang's emotions.

"After you hibernate, I hibernate first." After Chu Tianjiang changed his name, the program also took the initiative to change his identity.

"For what?"

"I'm not a scientist, just an intelligence officer. Because the Anthropocene realm has achieved great unification, people like me have no value in existence. Of course, it's also about you. Although I don't know where I'm hiding you after being erased by Melanie, the Earth Federation thinks that one day in the future, what I know about Ludao will come in handy, and maybe it will be able to restore my memory. ”

"So hibernate you?"

The figure nodded and said, "The next year, on the second day of the establishment of the Earth Federation, I entered a state of hibernation. ”

"What about the professor and Melanie?"

"On July 7, 2021, Dr. Melanie went into hibernation after completing all her research projects. Five years later, on August 9, 2026, Professor Law went into hibernation. ”

"They woke up with you?"

"I woke up first, about a week earlier than they did."

"See them?"

"Nope."

"For what?"

"There's no need for that." The figure smiled faintly, and his demeanor was very similar to Zhang Xiaogang. "Professors and PhDs are researchers and are under the care of the federal government. In addition, they have launched several scientific research projects in front of the East, so they will have relevant arrangements after they wake up. I'm just an outdated intelligence officer, and no one thinks that an intelligence officer like me will be useful in the coming war. ”

"That is, you are idle?" Chu Tianjiang laughed, a little bitter.

"Almost, oblivion, to be exact."

"And then?"

"The news you brought back from the Great Civilization is completely accurate, the invasion has arrived, but it is beyond everyone's imagination, completely unexpected."

Chu Tianjiang's brows jumped a few times, he had already seen the video materials, so he probably guessed it.

The invasion came suddenly and without warning.

On October 10, 2116 C.E., when the vast majority of people were going on with their usual lives, disaster befell everyone.

At that time, the civilian population almost forgot about the impending invasion.

According to the propaganda of the Earth Federation, the invasion will come between 2114 and 2116, and a powerful advanced civilization will take over the Earth and wipe out all humanity, so everyone will have to fight for survival and contribute to the common future of humanity.

These propaganda united everyone, but it also paralyzed everyone.

The point is that the invasion did not come in 2114, not in 2115, and not in the first ten months of 2116.

After more than two years of intense spending, the vast majority of people let their guard down.

It's just that the invaders have not forgotten about humanity.

Almost instantly, the Moon's gravitational field collapsed, and over the next month, the Moon became a huge stony comet orbiting the Earth, two-thirds of its mass breaking down into powder and spreading evenly across the Moon's orbit, forming a bright halo.

It's a beautiful aura, but it's also a deadly aura.

A month later, the remnants of the moon stabilized, and the imaginary invasion did not come.

No space fleets, no invasion armies, no aliens. It seems to be just a natural disaster, and humanity has not suffered a catastrophe.

Did the disaster just come and pass?

Of course, disaster has already arrived, and it is far from over.

The year 2117 became the first year of the disaster calendar, and mankind entered a period of disaster.

Scientists first recognized that the disappearance of the moon's gravitational field would trigger severe natural disasters that would lead to the extinction of many species, especially those that depend on the natural environment created by the tides, and would have a huge impact on almost all species, including humans.

The moon has existed for billions of years, and all life on Earth has been affected by the moon to a greater or lesser extent in the process of evolution. For example, the reproduction of some insects is affected by the gravitational pull of the moon. The moon's gravitational field suddenly disappears, and there is a good chance that these insects will no longer reproduce.

In response to this problem, the Earth Federation took immediate action.

Although human beings have mastered an inexhaustible source of energy, human beings are living beings and need a wide variety of organisms to suit any life cycle. If there is a mass extinction of life on Earth, even if humans survive, human civilization will not be able to continue.

To this end, the federal government of the Earth has established a biological gene bank.

Over the next year, the Earth Federation collected genetic samples from millions of organisms and built eighteen gene banks in various parts of the world and in space cities, preserving the genes of organisms in order to resurrect extinct species after the catastrophe had passed.

This is just the beginning, and the scope of the catastrophe has far exceeded all expectations.

The first to suffer is marine life, as well as life in coastal wetlands. The main reason is that the disappearance of the moon's gravitational field has led to a significant weakening of ocean tides, which has changed the marine ecological environment, making it difficult for the species that depend on these environments to survive, and extinction has become inevitable.

Immediately after that, global warming became a new disaster.

Although the impact on surface vegetation is not very noticeable, or not yet apparent, the amount of carbon dioxide in the atmosphere has increased with the extinction of the ocean's greenery and the many phytoplankton that have chlorophyll and absorb carbon dioxide through photosynthesis.

Sixty percent of the carbon dioxide emitted into the atmosphere is absorbed by phytoplankton in the ocean.

In response to this problem, the Earth Federation has built "oxygen factories" in various parts of the world, using the energy provided by controlled fusion nuclear power plants to absorb and decompose carbon dioxide.

Of course, compared with the disasters encountered, the self-help work of human civilization is a drop in the bucket.

For a whole century, human civilization has done everything possible to improve the ecological environment of the earth, and even developed some microorganisms that can adapt to the new environment, including phytoplankton, through genetic modification technology, and enhanced the survival ability of surviving species by human interference.

Unfortunately, in the past 100 years, more than eighty percent of the earth's species have gone extinct, and even higher plants have not been spared.

Self-help, which lasted for a hundred years, also crushed everyone's nerves.

Although the population has not decreased dramatically, the vast majority of people in the man-made ecosystem have survived this century, and the measures taken by the Earth Federal Government to control population growth have ensured that the vast majority of people can live a prosperous life while using the resources available. By the end of the first century of the catastrophic calendar, the total human population remained at about 10 billion. But the high-intensity labor that lasted for a hundred years, the natural disasters that never seemed to dissipate, the gradual depletion of various resources, and the various problems caused by the closed living environment caused serious social problems, leading to confrontation between the people and the government, and more and more people wanted to change.

Social contradictions have forced the Earth Federal Government to introduce a series of extreme measures, including an incentive to destroy the fabric of human society.

That is, only those who have made contributions can leave the earth and settle in space cities.

After the disaster, after receiving the advice of some scientists, the Earth Federation began to expand the space city, and decided to use the space city as an over-settlement during the disaster. To put it more bluntly, if a disaster leads to the devastating destruction of the ecological environment on the earth, the vast majority of human beings must settle in space cities, and after hundreds or even thousands of years, wait until the ecological environment of the earth returns to normal, and then return to the ground.

It can be said that this is an ambitious plan, but it has gradually changed in the process of implementation.

The key point is that when a disaster breaks out, the space city can accommodate a maximum of 500 million people, and the total human population exceeds 10 billion, and on average, only one out of 20 people can enter the space city. The question is, who will get the 1 in 20 chance?

Are you rich, are you in power, are you a scientist, are you a soldier?

Don't suffer from poverty, suffer from injustice!

Although the Earth Federation has introduced incentives for people who have made significant contributions to become residents of space cities and be eligible to settle in space cities, how to determine whether they have made significant contributions is a human factor that will be distorted in the implementation process.

One hundred and four years after the tribulation, in the year 2221 A.D., war broke out.

The war lasted for a very short time, less than half a year. Because the Earth Federation has the most powerful space fleet in its hands, the civilians who rebelled were brutally suppressed and forced to surrender after the rebellion failed. Less than a million people have been killed, but nearly 50 million have been exiled and deprived of citizenship and will not be eligible to settle in the space city for the rest of their lives.

It was Zhang Xiaogang who led the resistance and launched the war of resistance.

"Why do you want to resist?"

"Don't you think that immigrating to a spatial city is an inevitable choice?"

"It is indeed an inevitable choice, and it is the only way for humanity to avoid extinction."

"You think so, didn't the intruder think of it?"

"This ......"

The figure smiled and said, "The moon collapsed, the gravitational field disappeared, and a halo of dust appeared in the moon's orbit, which is simply impossible to explain with our scientific knowledge. This is clearly not a natural disaster, but the work of the invaders, whose purpose is to leave us without a choice. ”

"Forcing humans to migrate to space cities?"

The figure nodded, and his expression became grim.
