I! Pretending to Be Reborn, Director of Doomsday Hoax

Therefore, in the following time, as the environment was closed again, the oxygen content continued to decrease as before, and carbon dioxide and nitrous oxide exceeded the standard again.

Back and forth, the gates of Bio37 were opened [-] times to keep the system from collapsing.

Later, this Biosphere [-] collapsed completely. The high concentration of carbon dioxide caused the acidity of the artificial ocean inside to rise continuously, and a large number of fish and corals died.

Of the more than 4000 species of animals and plants in Biosphere [-], only six species of invertebrates, dozens of species of insects, and a few plants survived.

But the animals that survived by chance are also dying, and obviously can't last long.

Plants, on the other hand, cannot reproduce and are permanently extinct after death.

In the end, the rainfall in Biosphere [-] was also out of control. Due to the intensive rainfall, the man-made desert turned into jungle and grassland, and many plants grew in the swamp, and the stench was unbearable.

After two years of hard work, after completing the experiment, the eight volunteers were already skinny and looked like they were going to die at any moment.

Biosphere [-] also failed completely.

After that, Berry Country held a conference of scientists. After many discussions and consultations with experts in various fields, it was finally discovered that the problem was their clever concrete.

The two-meter-thick concrete poured under the ground was originally planned to create an airtight environment, completely isolating the ecological circle from the Blue Star.

However, this two-meter-thick concrete layer with an area of ​​more than 10,000 square meters has a wonderful chemical reaction with the carbon dioxide in Biosphere [-].

The carbon dioxide produced by the respiration of plants, animals, humans, and bacteria reacts with the calcium hydroxide in the concrete to form calcium sulfate, which leads to the loss of a large amount of oxygen.

Later, Berryland improved the facilities of Biosphere [-], which cost [-] million Berry dollars. Large-scale improvement projects and research were carried out to address the above-mentioned problems, and all concrete surfaces were sealed with paint to prevent them from absorbing carbon dioxide.

This time they invited an agronomist in. Although they solved the food problem, they still couldn't control the balance of the atmosphere, and they failed again.

Mei Shufang said solemnly: "It took Blue Star 46 billion years to evolve into what it is today. It is too difficult for human beings to create an artificial ecosystem."

"It can be stable for a day, and it can be stable for a month. However, with the current scientific and technological capabilities of human beings, it is difficult to stabilize for ten years.°

"To put it simply, it's too small, Director Xu! Even our super dungeon, with an area of ​​[-] hectares, is too small. Once any problem occurs with this size, it will not be able to buffer the destructive force by itself. !"

Huang He nodded and said, "Yes, no matter how precise this ecological circle is, it cannot stand the test of time if its area cannot reach a certain size."

Ouyang Tao said: "Even if the underground city is built into a city with such a large area as the Tiandu and the Demon City, this ecosystem is still too small compared to Blue Star!"

In the back row, Liu Mingying also stood up and said, "Director Xu, with the current human strength, I'm afraid it's not enough to accomplish this grand goal."

She hesitated and said: "Unless we can develop a super energy source, so that the output power of the entire human civilization can reach an astonishing level."

"For example, Dyson seeks, the vacuum energy level, or the antimatter energy."

"You know, if you want to do all this, even with controlled nuclear fusion, the energy may not be enough!"

Everyone was caught in a dilemma.

The man-made ecological circle has always been a difficult problem for biologists and the ecological circle. At present, it is not feasible to build a closed ecological circle only relying on the existing technology and manpower.

The professors of atmospheric science, biology, geothermal science, and physics in Longguo are all working in this direction, but so far, there has been no major breakthrough.

The Great Hall of Thousands of People has a heavy atmosphere.

Xu Qiu's face remained unchanged.

His super dungeon construction diagram actually included a part of the self-circulation system design.

Although it is not perfect, it can ensure that the subterranean atmospheric environment where human beings live can survive in a short period of time. This short period of time is about five years.

This is also the most important reason why he convened national ecological professionals to hold a dungeon ecological construction conference.

Five years later, the underground atmospheric environment may also be like Biosphere [-], gradually becoming chaotic, and then on the verge of collapse.

They can escape from Biosphere [-] and return to the atmospheric environment of Blue Star, but not in the dungeon of Dragon Kingdom! !

Leaving the dungeon, the outside is [-] degrees below zero in severe cold, human beings can't survive at all!

And other 3.5 countries, when they realize this problem, I am afraid they will panic even more.

Sakura Country is a train that goes around the country, with such a large area of ​​steel structure, and driving in the extreme environment of wind and snow...how do they achieve the balance of the ecosystem?

Longguo's nuclear-powered dragon is used to transport materials, and of course it also has its own melting ice and snow water collection system, which can store oxygen, and when it stays in the dungeon, it can take off the solid oxygen and melt it for use.

Moreover, the dungeon can also use its own surface ice and snow collection system to collect ice and snow.

The round-the-country train is facing an even greater crisis.

There are also the fortress of the Berry Country, the giant wall of wind and snow, and the giant ship of the Eagle Country, which will also face the same problem.

Xu Qiu remained silent. This is a question that all human beings in the world must think about.

"The extinction of the sun has made Blue Star's ecology extremely harsh and the environment is unlivable. Any country has to forcibly leave the Blue Star's ecosystem in order to survive."

"In the past, the artificial ecosystem was just a huge research result, and it was an important step to open up a space base and gain a firm position in the interstellar world."

"Now, however, this is our hope of survival... Without the artificial ecosystem, the dungeon will lose the balance of the underground atmosphere within five years, and will not be able to survive within ten years!"

"Other countries are even worse, and some countries may even die within a year due to the collapse of their respective ecosystems!!"

Mei Shufang and the others lowered their heads in deep thought.

This is a major problem related to the Dragon Kingdom and the survival of all human beings.

Behind the forest transplanting plan, it is not just a forest that is being protected.

What Xu Qiu wants is to use this forest to create an artificial ecological circle, so that these tenacious plants can help humans continue to experiment with a suitable ecological circle!

After a long time.

Xu Qiu's voice sounded again, and this voice made everyone feel at ease.

"Seniors, don't get too far ahead, start from the most basic, the biosphere, what are the most basic elements."

Everyone present knew the answer to this question.

An ecologist said: "Director Xu, we must consider its most basic elements, including animals, plants, microorganisms, air, temperature, moisture, and sunlight. Secondly, we also need to consider additional factors. To complete these, we Only then will it be possible to create a closed ecosystem."

Xu Qiu asked: "Sunshine, air, and temperature can all be controlled by humans. What is our difficulty?"

Ouyang Tao frowned and said, "Humans still have many uncontrollable factors, such as viruses... Although this thing is not very beneficial to us humans, it is indeed an indispensable part of the ecosystem.

O

Having said that, many people turned pale.

If the virus really disappears from the Blue Star ecology, mankind may face a catastrophe...

Although from the perspective of human history, the existence of viruses will only bring disaster and pain to humans. In the past thousands of years, viruses have claimed countless lives.

The influenza pandemic in the early 50th century killed [-] million to [-] million people.

Later, smallpox claimed the lives of [-] million people.

Temple..

However, the importance of viruses in this world far exceeds these disasters.

Contrary to common sense, the vast majority of viruses are not pathogenic to humans, and many play an integral role in supporting ecosystems.

In addition, there are viruses that maintain the health of an organism.

For example, viruses can increase photosynthesis in the ocean, thereby reducing carbon dioxide. It can quickly destroy harmful algal blooms caused by blue-green algae, and kill other marine organisms to maintain balance.And the most fascinating of them all is,

Viruses are organisms that walk on the boundary between life and chemical substances!

Without viruses, life cannot evolve, or even become life!

Human beings live in a great balance, which is so perfect that there is nothing wrong with it.

Is it really possible to reproduce all of this and create a perfect artificial ecosystem underground that can support human survival? .

Chapter 5000 [-] years of civilization, annihilated at that moment!

Zou Botao finally couldn't hold back anymore. He is a physicist who studies parity violation in weak interactions, and he is also trying to reveal the mysteries of the current universe.

This world is really too precise, so precise that even the slightest difference can usher in the destruction of all life.

However, it has found the almost impossible balance from it, and the billions of years of supernova explosions and expansions have always been maintained within the dynamic balance.

Zou Botao said in a deep voice, "Not only viruses, but also photons."

"We physicists are still exploring the generation of photons. The "Wukong" satellite of Longguo has two purposes. The first is to explore dark matter, and the second is to find the generation of light and the annihilation of photons."

Zou Botao looked blankly and asked: "Ordinary mass annihilation produces photons, so what will be produced by photon annihilation?"

"Just like the traditional myth of the Dragon Kingdom, when people die, they will go to the Hall of Yama, so where will the people in the Hall of Yama go when they die?"

Mei Shufang was shocked at the moment.

She didn't know the purpose of this dungeon ecological construction conference before,

But at this moment, when she knew that Xu Qiu was going to create an ecosystem that was independent of Blue Star and belonged to the dungeon, she was left dumbfounded!

Xu Qiu told a cruel reality, saying:

"Everyone, if in the past, the artificial ecological circle could not be established, we can find comfort in saying that Blue Star is the only home of mankind."

"But it's different now. After the sun goes out, Blue Star will turn into a frozen snowball, cold, frozen, and lifeless."

"We must save ourselves!"

"In the past, our studies were more in the sky, on Mars with its desert storms, Jupiter with its frozen oceans, and Venus with its corrosive gases."

"But now, we are just... building an underground ecological self-circulation system in a stable and safe underground city!"

Hearing Xu Qiu's words, everyone subconsciously clenched their fists.

Blue Star is the only home that shelters them, even in the era of extreme cold, it is still the same.

However, if they want to survive, they must isolate the ecology of the dungeon from the surface of the blue star and the atmosphere.

Compared with those chaotic and cruel planets, the establishment of an artificial ecosystem in a dungeon is of course simple.

However, it is still too difficult for human beings to create an artificial ecosystem with the current technology!

"Are you afraid?" Xu Qiu asked suddenly, his eyes swept across the crowd, calm and calm.

Mei Shufang stood up first, clenched her fists and said, "Don't be afraid! People from the Dragon Kingdom dare to build dungeons. People in the ecological field can't even create an artificial ecological circle?!"

Huang He got up and shouted: "Back then, they came here to dig grass roots and gnaw tree bark. They carried shovels and went to the swamp to dig soil samples. They almost died several times. Now that the Dragon Kingdom has advanced technology and everyone is like a dragon, why? Can't make it?"

Ouyang Tao doesn't like to say provocative words, he has already entered the state, and said: "At present, the biggest problem of the artificial ecosystem is that it is too small and lacks a buffer, so it is extremely sensitive!"
