Is there a better novel than Doomsday: simplify skills and build the strongest shelter?

There were many levels and elements to consider when building an underground doomsday shelter. From the perspective of a basic Level 1 primitive shelter, one could make use of a natural cave, equip it with basic shelter such as canvas or plastic sheets, store a small amount of canned food, bottled water, simple sleeping bags, blankets, and basic survival tools such as flashlights and matches. There might also be a small number of weapons. A Level 2 basic fallout shelter was to simply reinforce the cave or use wooden structures, add a small rainwater collection system, more food reserves, and basic medical supplies, set up a simple firewood stove for heating and cooking, establish basic sanitary facilities, and a small number of solar panels to provide limited power, and improve defense measures. The Level 3 medium fallout shelter was a semi-underground building reinforced with concrete. It had a small generator and battery system, a basic air filtering system, a medium-sized food and water storage, a small indoor planting area, a basic medical room (equipped with common drugs), simple communication equipment, reinforced metal doors, and surveillance cameras. The Level 4 Advanced Shelter was a well-designed underground complex with a long-term self-sufficient food production system, advanced water circulation and purification systems, stable and regenerative energy systems (such as small hydraulic power generation), a complete medical center (for surgery), educational facilities, entertainment areas, and an advanced defense system. Level 5 top-tier survival cities were large underground cities that could accommodate hundreds of people. They had a completely self-sufficient ecosystem, high-tech water and air circulation purification systems, a diverse energy system (including geothermal and nuclear energy), a comprehensive medical center (equipped with intensive care and research laboratories), large indoor farms and breeding facilities, manufacturing factories, a comprehensive education system, and the most advanced defense and monitoring systems. They also had the ability to conduct external exploration and resource extraction. American developer Larry Hall once transformed the underground launch well of the Atlas F launch vehicle into a luxurious "doomsday shelter" more than 50 meters underground. In short, the scale and level of construction of the underground doomsday shelter needed to be determined according to actual needs, resources, and technology.

I recommend a few novels. " If I Can't Cultivate, I'll Become a Saint Through Merit ", a Xianxia novel written by the Second Yellow River. The male protagonist, Fang Xu, had transmigrated to a world where cultivation civilization flourished, but he was cut off from cultivation. Fortunately, he had the mysterious bronze mirror. He would rely on burning merit and luck to improve himself and finally trample the world under his feet. This author also had the old book," From the Heroes of Martial Arts ". Doomsday Apartment was a science fiction novel written by Miao Zhu. After his grandfather died, he climbed out of his grave. His little friend mutated, and the apocalypse arrived. The style of this book was strange, similar to " Doomsday Paradise ". However, it was just a eunuch novel, but if more people read it, the author might continue to write. 'The Demon Hunter of the Kingdom of Steam', a light novel written by Su Zheng and Bai Xian. It was an oriental style steampunk story. The male protagonist, Mu Jiuge, wanted to retire. There were also special female protagonists, Chi and Yuan Baihua. 'The End of the World: Living with a Family' was written by Stiff Neck Fish. It was about the life of a large family during the apocalypse. There was a mobile invisible house and a "kitchen" that conjured delicious food. It was a sunny family outing. Doomsday Lord, written by Sleepyhead. In the novel of Doomsday Rebirth, the world was gamified. After the rebirth of the protagonist, Cheng Yang, he used the world as a chessboard to play the battle of Doomsday. Although it was flawed, it was not bad.

In some apocalyptic scenarios, there was the concept of doomsday aircraft carrier shelters. For example, in the setting of the game's doomsday, the world was faced with meteorites, zombies, ice ages, Zerg invasions, mutated beasts, and other disasters. It was difficult for humans to survive. Under such a setting, the Doomsday aircraft carrier could become a kind of refuge. It might have some special functions to resist the threat of doomsday, such as defending against attacks and providing living space. There were also some plots about the aircraft carrier traveling to a special period (such as World War II). Although it was not directly mentioned as a doomsday shelter, it reflected the importance of the aircraft carrier in special situations. In addition, similar to other doomsday shelters such as cabin ships and underground fortresses, the doomsday carrier shelter may also need to solve many problems such as resource supply, defense, and personnel survival.

With all kinds of doomsday prophecies and concerns about extreme disasters, some doomsday shelters appeared around the world. The prairie in Kansas, USA, was building a luxury " doomsday shelter " that was more than 50 meters underground. It was transformed from the underground launch well of the Atlas F-type launch vehicle. It could be used by super-rich people to avoid disasters such as solar flares, volcanic eruptions, terrorist attacks, or viral pandemics. Four buyers had already paid a deposit of 7 million US dollars, and three more were planned to be built after the first one was completed. It was reinforced and divided into 14 floors, some of which would be transformed into apartment-style suites. In addition, there were some places around the world that were not originally built to deal with the apocalypse that were considered potential doomsday shelters, such as scientific laboratories, underground tunnels, or luxurious underwater hotels. When the so-called " end of the world " came, these places might provide places for people to avoid disasters. Click on the link below to read the comic "The System Sent Me a Sanctuary"

The underground shelter was a kind of refuge for dealing with the apocalyptic situation. From a realistic point of view, the former fry had spent a lot of money to build secret underground nuclear shelters to protect its leaders. At the individual level, people like A'gang and A'ke built their own underground shelters in the wild. A'gang built his underground shelters using natural resources such as trees in the wild, while A'ke took into account many factors such as heat preservation, area, and concealment when building his underground shelters. In terms of gaming,"Underground Shelter" simulated the situation of the underground shelter in the apocalyptic scenario. The player played as a survivor to build and manage the underground shelter. He needed to lead the survivor group, manage resources, provide food and water, and carry out exploration activities. He also had to face various challenges and dangers and make decisions. The character relationships, graphics, and sound effects in the game presented the survival state of the underground shelter. In addition, in terms of social events, the basement of a furniture store in New York City became a temporary residence for immigrants (although it was illegal and there were many problems), which reflected that underground space could be used as a special shelter. Although it was different from the traditional doomsday underground shelter, it also reflected the shelter attribute of underground space.

The Doomsday Underground Shelter was an underground refuge facility built to deal with doomsday scenarios such as solar flares, volcanic eruptions, terrorist attacks, virus pandemics, wars, nuclear disasters, and so on. In terms of luxury and functionality, there were many different types. For example, American developer Larry. Hall built a luxurious " doomsday shelter " more than 50 meters underground in the prairie of Kansas. It was transformed from the underground launch well of the Atlas F launch vehicle in the United States, attracting super-rich people to buy it. There was also the transformation of an abandoned military base in South Dakota into " 575 military-built comprehensive risk bomb shelters made of concrete and steel." The area was almost the size of Manhattan, with facilities such as gyms, gardens, and cinemas. It was a large survival community. The luxury underground shelter at Lake Triton in Texas had 600 apartments, a golf course, and 12 helipads. The luxurious " underground residence " in Las Vegas covered more than 15,000 square feet and was designed to resemble an outdoor environment, including a " fake " sunset and barbecue grill. In terms of functionality, fallout shelters of different levels had different functions. It could be roughly divided into five levels: Level 1 was a primitive shelter, like a natural cave or a simple cave, with only basic shelter, a small amount of food and water, simple sleeping bags, and other basic survival tools. Level 2 was a simple reinforced cave or wooden structure with a small rainwater collection system, more food storage, simple heating and cooking facilities, etc. The Level-3 medium fallout shelter was a semi-underground building reinforced with concrete, equipped with a small generator, basic air filtering system, medium-sized food and water storage, and the Level-4 advanced fallout shelter was a well-designed underground comprehensive facility with a long-term self-sufficient food production system, advanced water circulation and purification system. A Level 5 top-tier survival city was a large underground city that could accommodate hundreds of people. It had a completely self-sufficient ecosystem, high-tech water and air circulation purification system, and other very complete facilities. In addition, there were shelter complex buildings like Survival Condo, which focused more on the concept of community. There were 14 apartments for sale, covering an area of 20,000 square feet. They were equipped with saltwater swimming pools, cinemas, grocery stores, and other facilities. There were also air and water filtering systems needed to ensure survival, as well as aquatic food systems. The 10-foot-thick concrete walls could withstand a 20-kiloton nuclear head impact. In addition to these fixed underground shelters, there were also some special forms of doomsday shelters, such as doomsday shelter cabin boats. The defensive cabin boats could withstand external attacks and bad weather. The luxury cabin boats were very luxurious. The self-sufficient cabin boats could provide food and energy. The wilderness survival cabin boats could adapt to the wilderness environment. The solar cabin boats were powered by solar energy. These different types of underground shelters reflected the different degrees and directions of preparation people made for survival in the face of the apocalypse.
