Chapter 5: Air defense engineering

　　 In fact, Chen Xin’s act of digging the refuge in advance is illegal in terms of procedures, because he has neither civil engineering approval nor project filing.
But in the face of the imminent doomsday natural disasters, the whole country has entered a state of emergency. All the manpower and material resources of the municipal departments have been invested in the transformation of the original civil air defense projects. The state also encourages itself to dig out shelters, so no one will take care of Chen Chen. The new underground bunker dug by myself.
The civil air defense project is a nationwide project that the Yan country has been building since the 1970s. Although there are no mountains and dews on the surface, there are actually a large number of civil air defense projects in major cities, but they usually don’t pay attention. That's it.
For example, the underground parking lot of a shopping mall or a residential area does not seem to be anything special except for the entrance and exit and the interior there are heavy lead gray iron doors, but in fact this is a civil air defense project. These underground parking lots have three defense capabilities. It can be used as air-raid shelter and refuge in wartime or even in the context of nuclear war.
　　 And now, in the face of possible meteorite impacts, the country is not only actively defending, but also vigorously transforming these civil air defense projects into shelters that can accommodate residents for a long time.
Because of the high temperature generated by the meteorite impact and the subsequent dust cloud and toxic haze, the earth's surface will become unsuitable for human survival in the next 100 years, with low temperatures and long periods of tens of degrees below zero. The dark night will be the only sight that humans can see on the surface in the next few decades or even hundreds of years.
　　 Therefore, under such circumstances, the refuge transformed by the underground civil air defense project will become the last home for human beings to survive and live in the next decades or even hundreds of years.
　　 Originally, these civil air defense projects did not consider long-term residential use. They were designed only for short-term shelter.
　　 And now that humans are likely to live underground in the next few decades or even hundreds of years, it becomes necessary to transform these civil air defense projects.
　　Especially after a meteorite impact, it will bring short-term high temperature and extreme cold extreme climate, which has higher requirements for the ventilation facilities of these civil air defense projects.
　　 Therefore, while the country has joined forces with other countries in the world to actively respond to the arrival of meteorites, municipalities and engineering personnel across the country have also been mobilized to upgrade and transform these civil air defense projects, as well as more critically expand them.
　　 Large underground facilities such as subway stations and underground shopping malls are being planned as future underground cities.
　　 After all, a facility that is buried deep underground like a subway station and can be connected to other subway stations at the same time is really an excellent choice for transforming into an underground city.
　　 This is actually one of the functions reserved during the construction and planning of the subway station.
　　 You must know that when the German air attacked London during World War II, Londoners escaped the German bombing by hiding in subway stations.
　　 In addition to the transformation of air defense projects, the reserve of various materials has also become the focus of the country's response to disasters.
Food will not be in short supply for the country in a short period of time. The country’s food reserves are sufficient for the country to eat for three years, but most of the food is concentrated in granaries across the country. Now it needs to be transported to distribute the food from the granary to various In the planned refuge in the city.
All tasks are being carried out in an intense and orderly manner. Although some people want to take advantage of this kind of panic, they want to engage in trouble or supplies, but under the premise that the state has implemented a state of emergency, the police are no longer responsible for maintaining law and order. It is the army, and these people who want to die will naturally be attacked by the army, fulfilling their wishes.
　　 Under the country’s overall planning and strong control, most of the shelters have been completed on schedule, and material reserves have been put in place, which can accommodate people to enter them for refuge.
At the same time, considering that the place where the meteorite might hit the Pacific Ocean, people in coastal areas were evacuated to the inland areas. Although this has caused serious losses to the national economy, at this time, in the face of a possible huge tsunami. It is impossible for the country to put hundreds of millions of people in the southeast coast at risk for a little economic benefit.
Just like Taizu’s famous saying,
Land lost, people and land are lost; people and land are saved, people and land are saved.
As long as people are alive, the city can be rebuilt without people, but if people are gone, who will carry out the post-disaster What about reconstruction?
In just a few months, the country has to prepare a plan to deal with meteorites as well as prepare for disaster prevention across the country. Even in a country like Yan State, where the government has strong control, it must do its best. With one heart and one mind, I can barely finish most of the work in such a short time.
　　 In countries where the government has insufficient control, society has fallen into a state of collapse.
Small countries in Southeast Asia, the Middle East, Africa, and Latin America and other places lack the government's ability to respond to this hierarchical crisis. At this time, the order of the entire country has collapsed, and the society has entered a state of disorder. .
　　 For a package of food, people in these areas may draw guns and fight each other and cause death. A life is not even as valuable as a piece of bread.
　　At this time, in these areas, humans have returned to the most primitive state of the weak and the strong, and humans are no longer much stronger than the beasts. The only thing they think about is how to live.
　　 Although this is the same as the thinking of people in other areas who are still under order, the ways in which the two sides achieve this goal are very different.
If it were before, other countries might still lend a hand to the chaos in these regions and the disasters they are facing, but now all countries are overwhelmed. Even the best Blue Star five can only guarantee that they are facing this situation. In the face of a global catastrophe, they can protect themselves.
In fact, even among the top five Blue Stars, only Yan State, where the government has a high degree of control over the country, is in the best condition. Although Britain and Gaul are not in a state of disorder, the society is still chaotic, with a large number of demonstrations and demonstrations. The riots still made the governments of the two countries struggling to cope.
As for Lucia, the situation is much better than that of Britain and Gaul. Especially as a former superpower, Lucia inherited most of the legacy of the red regime at the time. In response to this global catastrophe, it was entrusted to them. With the blessing of the red heritage, coupled with its own geographical environment and climatic conditions, Lucia did not experience much chaos, and the situation is much better than that of Britain and Gaul.
　　As the only existing superpower on the Blue Star, the situation of the Federation seems a bit strange.
