After the Spring Festival in 2020, it began to rain all over the world, and the rainy days continued, ten days, half a month, one month, two months...... After three months, everyone panicked, and everyone felt that the weather was abnormal, and they couldn't feel at ease. What worries them even more is whether it is sea water, river water, lake water, river water...... All of them are rising horizontally, and there is no downward trend. The water has flooded many streets, some low-lying places, and even to the height of a person.

People all over the world are clamoring for scientists and countries in the field to come out and say what is going on now. When will the world-wide floods recede?

The leaders of every country in the world appeared on the national television stations of each country together, and announced to the people a desperate news for everyone: this global flood is just the beginning, the earth is about to enter the end of the world, the sea water will be accompanied by a tsunami to flood the whole earth, and there is no room for human beings on the earth.

Everyone is stupid? Is today April Fool's Day? Why are all the leaders telling the same joke? But seeing the leader's pained expression on TV, everyone's hearts sank. It's not a joke, the earth is really going to end, and the earth is going to be swallowed up by the sea. The living space of human beings was eventually occupied by marine life. So what are they going to do? Waiting to die?

Everyone was at a loss. However, some people have confidence in the government and the leaders, and they feel that it is impossible for the leaders not to make arrangements after learning the news of the end of the world, they must not want to die, and it is impossible for them to watch the death of mankind.

These smart people quickly figured out that they didn't scream hysterically like everyone else, they didn't think about killing themselves like some people with poor psychological tolerance, they sat quietly in front of the television, waiting for the leaders to say what they wanted to say, to see how they arranged the people.

Without disappointing them, the leaders spoke out the arrangement.

First, after many years of painstaking research, scientists from various countries have built a space fortress and 10 spaceships. The nations will select the best two million people from all walks of life in the world to enter the spacestar and spaceship, and leave the earth to immigrate to Mars with the seed and pups of all the plants and animals on the planet, as well as the sperm and egg banks of every race on the planet.

Although it has been proven that the colonization plan to Mars is stupid, whether it is the temperature difference between day and night, excessive oxygen and various radiations on Mars, it is very harmful to humans. But now there is no way, Mars is the closest planet to the earth, and it is considered a planet with less harm to mankind than other planets, and with the current technology of human beings, the spacestars and spaceships made can only reach Mars at the farthest.

In order for humanity to have a glimmer of hope, these people had to be sent to Mars. Fortunately, scientists have taken into account the actual situation on Mars and have given corresponding countermeasures, so that those who live on Mars can survive on Mars. Although survival will be very difficult, they are all the best and brightest people on Earth, and they believe that with their abilities, they can gradually change Mars and build a living circle suitable for human life there. If they can't say that the time comes, they can send spaceships and Battlestar back to Earth and bring people who are still alive to Mars.

In the second arrangement, countries will establish air bases in the world's highest mountain ranges, such as the Himalayas, but because of the climate of these mountain ranges, it is very difficult to build, and the air bases are very small enough to accommodate less than a million people.

The third arrangement, the construction of security bases on the ground, after the sea covers the world, these bases are in the sea, which is equivalent to the sea base. The problems to be solved in these bases are no less than those in the air bases, such as the solution of seabed pressure, the problem of air conversion, etc., all of which are one problem after another. Although scientists have overcome these obstacles, due to various restrictions, these submarine bases are also small and not very numerous.

With the current science and technology, the largest area built by the submarine base is only equivalent to the size of a fourth- or fifth-tier city in a flower-growing country, and the capacity is only two or three million in the sky - this is still under the condition of crowding - there are a total of 200 undersea cities built in the world, and the total number of people can be up to 600 million, and then squeezed out, the maximum number of people is 700 million.

Today, the world's population is more than seven billion, and less than a tenth of the total number of people survive under government-provided security measures, and the other nine out of ten lives are abandoned.

The whole world was in an uproar, everyone panicked, and the people who reacted quickly immediately began to act for the one-tenth place, fighting for this chance to live.

Xiao Anan stared at the TV, unable to close his mouth for a long time. , no wonder her heart has been unstable, and she has been constantly trying to improve her strength, it turns out that the end of the world is really coming! But the end of the world is not a zombie siege or something, but a flood of the world, even if her personal force value is superb, it is useless in this situation. Will her strength be enough to keep her alive in the water? No kidding, she's not an amphibian.

What to do? Do you want to go for that one tenth chance? Xiao Anan felt that she might be able to win a place, after all, she had been a technician who had received the attention of the National Academy of Sciences, and the submarine base should need such talents, right? But it's hard to say that I'm just an orphan, with no power or power, and I can't say that I finally won a place and was taken away by those powerful people.

Speaking of the National Academy of Sciences, I think they have thought about whether they have thought about including themselves in the construction project of the submarine base, right? Why didn't you absorb yourself later? She didn't know why.

Looking at it now, it turns out that the scientific and technological knowledge of this world is not as backward as I imagined, in fact, the secret scientific and technological level has been ahead of the current announced scientific and technological level for many years, otherwise it would not be possible to make a science fiction product such as a space fortress, an air base and an undersea base. The scientists who developed these technologies seized the time and raced against time to work for the continuation of human beings on the earth, so they did not publish the results of their research to the public, right?

Xiao Anan is very excited about these successes, with these achievements and knowledge, it will be easier for him to comprehend spatial knowledge, right?

Itching, Xiao Anan turned on his computer and wanted to use his hacking knowledge to get these results.
