I! Pretending to Be Reborn, Director of Doomsday Hoax

And no one has experience in actually building a house built underground.

What's more, most of these underground streets and commercial streets are only distributed at a depth of ten meters to 30 meters underground.

The construction of the underground city in the Dragon Kingdom is planned to be between 50 meters and 100 meters underground.

Everyone feels suffocated when they think about this scene...

Most of the tall buildings in the city are between ten meters and 30 meters.

If the building is controlled within ten floors, virtual simulation technology will be installed on the top of the dungeon to simulate the original sky and provide light sources at the same time.

Then, when people walk on the streets of the underground city and look up to the sky, the bright sky will look exactly the same as the surface of the earth before the sun went out! !This is an extremely exciting scene.

The second difficulty of the dungeon lies in the design drawings.

To build a city on the surface will exhaust the energy of all the top engineers in the country, arranging all kinds of roads, drainage pipes, power lines, natural gas lines, water conservancy pipelines, etc... And the underground city, except for everything that the city above the ground needs, A system for constantly supplying oxygen and a system for absorbing carbon dioxide are also required.

The underground city needs a complete air system to replace the original atmospheric circulation on the blue star.

The most terrible thing is that the dungeon is built artificially. Although there is artificial light that can maintain the photosynthesis of plants and continue to produce oxygen, the amount of oxygen is really negligible.

Blue Star's original oxygen came more from the vast forest, the rich algae plants on the sea surface, and various microorganisms.

And as humans turn to live in dungeons, all of these will disappear, and humans have to rely on their own technological strength to produce oxygen.

Coupled with the fact that the surface temperature has reached minus two hundred degrees, even if there is a more than 50-meter thermal insulation layer above, there will probably be terrifyingly low temperatures penetrating into the air in the dungeon.Therefore, the underground city has to be additionally equipped with a heating system that surrounds the entire city.

How to repair and replace, how to ensure that it will not be damaged by severe cold, these are big problems!

Compared with these problems, it is not so important to be unable to gather the power of the people, and to be unable to build a dungeon with the power of the whole country.

This is also a major reason why countries such as Berry Country and Cherry Blossom Country do not choose dungeons and instead adopt other methods to fight against the extremely cold era!

Their "sunset meeting" has lasted for more than three hours. With people's discussions, the despair in the hearts of the Prime Minister and others has deepened.

"I really want the universe to be destroyed." Kamo, the founder of physics in Eagle Country, stood up and sighed.

"Actually, compared to the destruction of the universe, the blue star after the sun goes out is more terrifying to humans!"

This sentence caused many people to raise their heads in surprise.

The prime minister didn't understand either, and asked, "What do you mean, the destruction of the universe, what kind of scene is it?"

Kamo took the initiative to walk to the podium and said to the crowd below:

"Actually, there are many theories about the final outcome of the universe. Some physicists believe that the universe will be torn into subatomic fragments by the ever-increasing dark energy, and some scholars believe that the universe will be destroyed when burnt growth reaches its highest point and then fall into heat death. The big freeze, some people think it will be a big rebound that shrinks to the extreme again..."

"However, my teacher, Laughlin, used a lifetime of theory and knowledge to draw a more authoritative and reasonable conclusion. He believes that if the sun does not go out, our universe will go through five epochs!"

"The first is the original era."

"The origin of the universe, we in the physics community, generally believe that it came from a big bang. Until [-] million years after the big bang, the first star was born, so the era belonging to the original era passed. This era lasted [-] million years, until a planet is born."

"The next is the Stellar Era."

"In this era, the stars dominate the entire universe, and the sky is full of stars, and we are fortunate to live in such an era."

"If the sun does not go out, we will continue to survive. According to the calculation of the model, the sun will not go out for about 5 billion years."

"In astronomy, there is a law that goes against common sense. The smaller the mass of a star, the longer its lifespan and the slower it goes out!"

"Because they convert hydrogen to nitrogen very slowly during nuclear fusion. And the smallest red dwarfs can last a trillion years. Red dwarfs formed when the universe was young take billions of years to burn up

About one percent of the hydrogen in the interior is removed. "

"According to the calculation method of human life span, it has just completed the sperm-egg combination, and there are still infinite years before natural old age and death."

"During our stellar epoch, galaxies stirred up nebulae, using the nebula's gas to create new stars."

"However, when the gas is exhausted, no new stars will be formed, and the stellar era will begin to decline."

"We predict that after about one billion years, the supply of nebula gas will continue to weaken, and fewer and fewer new stars will be born, while the stars that have already been born will continue to undergo nuclear fusion, exhausting hydrogen and extinguishing one by one."

"Occasionally there will be events like galaxy collisions, creating some new stars, extending the time of the stellar epoch, but it has little effect."

"When a large number of stars die out, that is, at the end of the stellar epoch, galaxies will change color, and most galaxies will appear dazzling blue-white. By the end of the epoch, most of the surviving stars are low-mass dim stars. Tint entire galaxies dark red."

"And when the last star is destroyed, the stellar epoch of the universe is completely over, and a new epoch comes, which I call the degeneracy epoch!"

"Compared to the stellar epoch, this epoch is particularly monotonous. There are only star corpses left in the universe, and white dwarfs, neutron stars, and black holes are everywhere."

"In addition, there are some brown dwarfs distributed throughout the universe, which are between stars and planets."

"The reason why it is called the degeneracy era is that in addition to black holes, in this era, white dwarfs and neutron stars are supported by various degeneracy pressures."

"During the degenerate epoch, the universe returned to cold and dark."

"And the neutron stars and white dwarfs that used to have high temperatures that we fear, and the stars that used to reach tens of thousands of degrees or millions of degrees, as the years passed, their temperatures dropped to room temperature in the degenerate epoch."

"The entire universe will be plunged into extreme cold."

"Of course, it's not without light."

"When the two white dwarfs finally approach, their orbits decay due to gravitational wave energy radiation, and the binary stars successfully merge. At that moment, the entire universe will burst into dazzling light, and the two white dwarfs will also merge into one and become a supernova!"

"Similarly, two neutron stars also have a chance to merge and explode, and that is a gamma-ray burst!"

"And the brightness of their light when they erupt will exceed the total brightness of a thousand galaxies!"

"And when the white dwarf cooled to become a black dwarf, the neutron star also cooled completely, disintegrated and melted into the universe, and the degeneracy era ended."

"The era of black holes is coming!"

"In this era, there are only endless black holes left in the universe."

"And in the end, the black hole also disappears, everything disappears, and the age of the dark era has arrived. At this time, only subatomic particles and photons with extremely low energy are left in the universe. At this point, the universe is also extinguished."

"Belongs to the last epoch of the universe, and the dark epoch is also over."

At this moment, the prime minister and others suddenly felt that they were so small.

For stars, the lifespan is calculated in billions, billions, and trillions. Such a time span is equivalent to eternal life for human beings with a lifespan of 100 years in just a few decades.

Kamo sighed, his eyes filled with melancholy, and said: "If we develop according to these five epochs, we human beings will not feel pain, and will be destroyed in an instant supernova explosion or galaxy collision." "The entire Blue Star It will all be gone!"

"But now, after the stellar era, there is another extremely cold era belonging to humans!"

"If we don't fight, this era of extreme cold will slowly take our lives and become beautiful ice sculptures."

"Dragon Kingdom is in the dungeon, enjoying fine wine and cigars, while we are struggling and fleeing for our lives in the extreme cold. This is the cruelest thing!"

Everyone's face was icy cold.

Thinking of this picture, they felt unfair.

Why can Dragon Kingdom do this.

How can the people of Dragon Kingdom be so carefree.

Why can Dragon Kingdom own Xu Qiu! !

"Our country lacks Xu Qiu."

"Is there a way to ask Xu Qiu to help us design the dungeon?"

"Impossible. Didn't you read his speech at the press conference? Such a person cannot be moved by any interests."

"Even if we take the position of Prime Minister as a promise, or even exchange the wealth of the entire Eagle Kingdom, Xu Qiu probably doesn't care. In the extremely cold era, the most indispensable thing is land and money. Only steel, machinery and various Kinds of building materials are the hard currency!"

"As for money...it's just a toy that was born after the initial stage of the disaster and the stability of the order!"

The Prime Minister was originally in an irritable mood, but he was even angrier when he heard that his subordinates were so frustrated.

"Shut up for me."

The chamber fell silent.

The prime minister looked at Kamo and asked: "Mr. Kamo, do you have any method to allow us to survive this doomsday. Or, in the face of the Little Ice Age two months later, how should we fight against it? " Kamo thought for a while, and said: "Your Excellency, I do have a few methods."

"you say!"

"The first method is the most cowardly."

"Since we are not strong enough as a single country, why not join forces with Bear Country, Maple Leaf Country, Nordic countries and other countries that are located in high latitudes and struggle with ice and snow all the year round to fight against this doomsday?"

The Prime Minister shook his head, "This method involves too many things. Besides, we had a serious dispute with Ouzhou some time ago. Wouldn't it be a joke to join forces at this time?"

"Tell me about your second method."

Kamo's emotions suddenly rose, and there were memories of the past and infinite honor in his eyes.

"I still remember that our Eagle Kingdom was once known as the empire on which the sun never sets. The great ships and footprints of conquest have traveled to every place in the world..."

"Relying on gunpowder and advanced warships, we conquered a large amount of territory, so that in the end, our land spread all over the world. When the sun set on the eagle land in the west, the sun rose again on the land in the east!" the Prime Minister interrupted He said: "Mr. Kamo, the glory of the empire on which the sun never sets has passed for a hundred years, and now we need to survive the Little Ice Age and the end of the world!"

Kamo smiled and said, "Your Excellency, this is exactly my plan!"

"We have the world's top shipbuilding technology and technology, advanced shipbuilding drawings and skills, and our designers, engineers and workers also have a lot of experience..." Everyone heard this, already I think it's outrageous.

The Prime Minister couldn't bear it anymore and asked: "Under the severe cold on the surface, the sea water has already condensed. You built a boat to drive on the ice?"

"Yeah, not only that! We're going to drive through the ice!"

Kamo looked fascinated, with a look of madness in his eyes, and said:

"You know what is scarcest after the sun goes out?"

"If you want to build a dungeon, what is the most missing thing?"

"Two things, oxygen and water!"

"Under the ultra-low temperature of minus two hundred degrees, even oxygen will condense into a light blue solid!"

"Fresh water resources will also be very scarce, groundwater may be frozen, and freshwater lakes and rivers on the surface, without exception, will all become part of the ice layer!"

"And if we can design a giant ship..."

"This ship has a thick, sharp edge, it can split the ice, and then collect the ice. Send it to the bottom boiler power room."

"These ice cubes melt under the high temperature of the boiler power room and enter the recovery system to be converted into oxygen and fresh water. At the same time, its temperature can also keep the blast furnace power room continuously cooled, improving the performance of the giant ship!"

"This giant ship will be very large and can accommodate millions of people, or even more. It will be wrapped in a thick outer wall to isolate it from the severe cold of the surface."

"On top of the giant ship, there are tens of thousands of huge high-heat iron furnaces, which can continuously heat the sealed giant ship."

Hearing this, the suspicion in everyone's eyes was gradually diluted, and more and more people showed a look of sudden realization.

A mechanic stood up and said, "The giant ship plan is completely feasible!"
