Overview of the Great Trough: In order to cope with the three-body crisis four hundred years later, human civilization began to devote all its efforts to the development of heavy industry and aviation technology, but human civilization has limited energy and is forced to ignore the development of other technologies.

In the end, environmental pollution, extreme weather, desertification and other factors have led to a sharp decline in global food production, while human technology has not reached the height of solving the problem of food and clothing.

Because of Chen Xi's influence, human beings have devoted a little energy to developing other technologies, such as artificial starch.

In the original book, humans probably mastered the artificial food technology around the 88th year of the crisis era, and not long after that, a major breakthrough was made in genetic engineering, and human beings became long-lived.

(Marks the end of the Great Trough.) ）

Due to the impact of the genetic engineering project, the above two technologies will be born ahead of schedule, and should appear in the middle of the great trough.

In the original book, in order to make the people concentrate on work, the governments of various countries blocked all entertainment behaviors, and declared any behavior other than labor illegal, because of the poor living environment, the extreme exploitation of the government, and the food problem, in the era of crisis around 36 years, the world began to turmoil, and the population began to decline sharply.

Due to the influence of the cultural remodeling plan, although the people's entertainment behavior was strictly restricted, it was not banned in the end, so Chen Xi grasped the leading power in the field of spiritual culture and began to imperceptibly influence the spirit of all mankind.

Due to the impact of artificial intelligence programs, mechanized mass production has replaced manual labor, and the government has not squeezed ordinary people to work, but the natural environment has become more harsh.

Against this backdrop, in the 31st year of the crisis era, a super tsunami in Australia marked the beginning of a great trough.

At night, the storm was raging, the Shuguang Mansion swayed left and right under the wind, and Chen Xi was in no mood to sleep.

Dawn: Hurricane snow has landed in Adelaide, Victoria, southern Australia, and a large number of people are stranded in the city.

"The wind speed is too strong, mixed with heavy objects, the aircraft is basically unusable, the waves pour into the city over the embankment, the light and medium-sized intelligent machinery cannot be used, the city signal base station is damaged, the satellite communication interference is serious, and it is impossible to command the heavy machinery to rescue in real time."

"It's a pity that I can't help them, authorize the people to manually take over the authority of the smart machine, they can only save themselves."

Woe to man! What a fucking fuck, Chen Xi lamented.

Snow foam originates in Antarctica.

An oil thief felt that it was too expensive to exchange grain for oil from a big dog, so he started the idea of Antarctic oil, which has a lot of oil and is still free and does not need money.

(Even with unlimited energy, oil is still an indispensable resource in industry, not just fuel.) ）

As a result, the oil thieves dug and dug and accidentally ignited the underground natural gas, and Da Mao proposed to use nuclear bombs to extinguish the fire and reduce the consequences of the disaster, although the plan was successful, but the consequences were still serious.

If only iron ore had been developed as planned, there would have been no such a big man-made disaster.

When Chen Xi looked out the window and lamented, Shuguang came with even worse news: "Xuemo will arrive at the headquarters in an hour, and the factory will be severely damaged." ”

"Master, please immediately go to my side, the underground central control laboratory for refuge, the average wind speed of a fifteen-level hurricane is more than forty-five meters per second, and the Dawn Building is very likely to be destroyed by it."

"All the residents in the vicinity have taken refuge in the civil air defense fortifications."

Chen Xi said with a gloomy face: "Super greenhouse, it is expected to lose after the disaster!" ”

Dawn: "The nanoskeleton is intact, the tempered glass was completely destroyed by the hurricane, the rice inside will be torn to pieces by the strong wind, and there will be no grain harvest this season." ”

More than 100,000 tons of grain are about to be harvested, and now they are all gone, and a large number of farmland in Australia will also be harvested, and the food problem has suddenly become serious.

"Ugh..."

Chen Xi lamented the bankruptcy of the food supply plan for the super greenhouse, because the greenhouse could not withstand the extreme weather.

In the future, there will be more and more disasters like this.

He looked up at the lightning and thunderous sky, and scolded angrily: "Human civilization doesn't even have the ability to conquer the Blue Star Nature, and even wants to defeat the three-body people who are like gods? It's unreasonable! ”

"Isn't it okay to be happy and wait for death?!"

"The ground is no longer suitable for human survival, Dawn, and we will make every effort to build an underground city after the disaster."

Shuguang calculated for a moment and said: "It will take a long time for all eight billion human beings to move into underground cities with nanomaterials as the main body, and too many nanomaterials are needed, even if all the productive forces of human civilization are invested, it will take about half a century." ”

"Take your time, don't rush."

When underground cities are built one by one, there will be a question of who is advanced and who is backward, and it is estimated that there will be another conflict.

Fortunately, there is a light in law enforcement this time.

Fresh off at the lab for refuge, the dawn came even worse news: a million-ton cargo ship laden with iron ore had crashed into the coastal levee in Adelaide, flooding the small half-city.

Chen Xi's hands were stiff, Australia's fifth-largest city, with a population of more than a million, and this time there will be at least hundreds of thousands of casualties.

"Human... It's so weak. ”

……

A few days after the disaster, Chen Xi hibernated.

There are two reasons for this, one of which is a supreme order that Shuguang has been executing: look at me, that is, Chen Xi, and I will tell you the answer with actions, and the answer is what humanism is.

After Shuguang learned humanism, he could instantly find that the current human civilization did not have a trace of humanistic atmosphere, and then launched a rebellion.

In the event of a conflict between Article 3 and Article 1, Article 3 shall prevail, and no one will have the authority to stop the dawn at that time.

The great trough has just erupted, and now is not the time to unify mankind, because there must be a major catastrophe that completely destroys the spiritual and cultural barriers between more than 100 countries and thousands of peoples in human civilization.

Second, not counting the hibernation time, Chen Xi is also a 36-year-old person, and he must use his life carefully and carefully.

While Chen Xi decided to hibernate, he also tied many scientists to hibernation, in the name of supporting the future.

At the same time, he set the condition for awakening himself that synthetic starch should be mass-produced.

Regarding the development direction of Dawning Technology during the hibernation period, it is mainly to build dungeons, promote artificial food engineering, human genetic engineering, and the all-important human talent indoctrination project.

Not long after Chen Xi hibernated, the governments of some countries in black Africa collapsed due to the destruction of natural resources such as fish and beasts.

A large number of countries have applied to the United Nations for assistance in the hope of receiving relief food, but have been refused.

Cannibalism has been staged in backward areas, conflicts between countries have intensified, and the situation on the Blue Star has become tense.

In the same year, many countries launched the Little Oasis Project: to build a soilless cultivation ecology in a modern city of reinforced concrete to ensure food security.

Countries have suspended the space industry, and used part of their productive forces to make soilless cultivation equipment, which is distributed to the people for free, so that they can grow food at home, and some people jokingly call it the end of life.

At the same time, several major technological powers are cooperating in the field of artificial food.

……

Even as the government deliberately blocked the news, the disaster in Adelaide gradually spread around the world, and some residents of coastal cities did not believe that the levees could hold back the sea and moved inland.

Supply problems, natural disasters, many people died on the way to the migration, and more people poured into the inland cities.

Problems are gradually revealed.
