Darkness is Coming

   Zeng Bo never expected that he would actually take a brief military theory class in this chat room.

   But after thinking about it carefully, what Instructor Cheng said really makes sense. Although Zeng Bo knew nothing about military theory, there is one thing that military blinds can think of: those monsters that emerge from the gray cracks will not stay in the deserted steel forest, they will definitely be in this area that is very dangerous to them. Explore a whole new world.

In this way, war is unavoidable. Even if the Chinese government gives up Shanghai to preserve the overall situation, the monsters will not stop at the border of Shanghai City. They will inevitably pose a threat to the life and property safety of people in other areas. So they must be intercepted within the line of defense.

   If you use passive defense, you need to arrange multiple lines of defense to block it, which not only increases the difficulty of defense, but also increases the casualty rate while consuming a lot of resources. It is completely a thankless play.

From another perspective, since most of the important assets have been transferred and the residents have evacuated from the urban area, after bearing some industrial losses that cannot be transferred, Shanghai is no longer a big city, but a meat grinder— —In the past few days during the evacuation work, Zeng Bocai learned that Shanghai is not only an economic, financial and trade center, but also the largest comprehensive industrial city in the country, and some industrial facilities such as metallurgy, machinery, shipbuilding, and chemical industry are not as easy to transfer as the population. , can only reluctantly sacrifice.

During the southern capital defense battle, in order to avoid accidental injury to civilians, the troops entering the city did not use large-scale high-power destructive weapons. Only a few suburban locations were covered by artillery fire after the evacuation of the people, and now Shanghai is about to become an empty city. There is no problem of throwing the mouse, no matter what kind of powerful weapon, you can say hello to it.

  If the behemoth of war in the Nandu Military Region goes all out, the fangs it can use to kill not only guns and missiles, but also chemical and biological weapons.

Therefore, perhaps Instructor Cheng is right, the withdrawal of Shanghai is not because the troops have no confidence in winning, so they gave up the struggle and surrendered the country, but because the above believes that ensuring the safety of the people is more important, and closing the door to fight dogs can greatly By improving the efficiency of killing monsters, the actual losses suffered by the country will be reduced, and at the same time, the personal safety of the people will be guaranteed. As for the property of Shanghai citizens, they can only be sacrificed to take care of the overall situation. This choice is indeed cruel, but the personal safety of the general public is always more important than some property. The only thing the country can do is to wait until after the war to try to make up for the unfortunate people in Shanghai.

On the other hand, because the defense line is located on the edge of the city, there is no possibility of accidentally injuring friendly troops. When the monsters of the magic tide appear together and gather in large numbers in the city, they can carry out ground-washing bombing on the city that has been abandoned. It saves time and effort, and the guards on the edge of the city, relying on the blood transfusion capabilities of national roads and expressways, are not difficult to intercept all the fish that slip through the net within the defense line.

   Thinking down this line of thought, maybe those bunkers were really built to protect troops inside and outside the defense line during a nuclear explosion.

The above order is very clear. Except for the defenders and the relevant personnel who have a stay permit, all the others will be withdrawn from Shanghai. This huge city is unmanaged, and various problems will arise soon. plans for the city. This is not impossible. Having witnessed various events in the past year, Zeng Bo has learned a truth: never underestimate the decisiveness and courage of Chinese leaders in critical moments.

Thinking about the battle of Yuanjiang, in order to exterminate the zombies and mutants in the city, the Air Force dropped a large number of sub-munitions in Yuanjiang City, which made Yuanjiang City unable to resume use in the next ten years or even decades. Since there is a precedent, then It is not impossible to drop a nuclear bomb on Shanghai this time to solve the magic tide.

As a science student, Zeng Bo is not easily misled by the exaggerated reports made by unscrupulous media to attract attention. Although he is not clear about the true power of nuclear bombs, Zeng Bo is convinced that nuclear weapons are not as terrifying as popular perception. , so Zeng Bo will not talk about nuclear discoloration like others.

In fact, it is impossible to see the kind of nuclear war wasteland described in third-rate science fiction, such as "the nuclear explosion area still has deadly radiation and becomes a forbidden area for life hundreds of years after the nuclear explosion", "the surrounding area of ​​the nuclear explosion Organisms are affected by radiation and genetically mutated, turning into giant deformed monsters with terrifying destructive power” and other links are just baseless conjectures.

   As far as Zeng Bo knows, the fallout from modern nuclear weapons is not as terrifying as most people think unless it is deliberate. Generally speaking, nuclear explosions will be air explosions. However, in large cities such as Shanghai, where there are many high-rise buildings, air explosions are difficult to form effective radiation fallout killing. Usually, one to two weeks after the nuclear explosion, the radiation dose in the radiation area will drop. To the non-lethal level, if you are healthy enough, you can try to leave the safety bunker for a short time and go out to seek rescue 48 hours after the nuclear explosion.

   As for the statement that "radiation rays can penetrate everything, hiding in bunkers is futile" is even more ridiculous. If the safety bunkers do not work, how can the major bunker manufacturing companies receive orders that float like snowflakes? Could it be that the government and the rich who spend money to make bunkers are all fools?

  Theoretically, some rays can indeed penetrate the protective layers of all shelters and bunkers, but in fact, there are multiple protective layers filtering, and the residual radiation will not cause harm to the refugees hiding in the bunkers.

  For radiation to cause harm to the human body, it must first reach a certain dose. Many people do not know that there is actually a large amount of uranium hidden under the seabed. However, fishermen living by the sea will not suffer health damage due to this slight radiation.

Therefore, the role of the bunkers is basically clear. It is used to allow the defense forces to avoid the radiation fallout damage caused by the large-scale nuclear explosion. When the radiation dose in the urban area gradually decreases, the soldiers hiding in the bunkers have to leave the bunkers to continue fighting, because Huaxia's nuclear weapons have been on the road to miniaturization and precision since they were successfully developed. Especially after the nuclear disarmament in 2009, there are not many large-yield nuclear bombs, and there are no big ones like Tsar bombs.

With the power of nuclear warheads in Huaxia's armament, it is impossible to raze Shanghai to the ground if a few are thrown, and it is not desirable to wash the ground with nuclear bombs. First, it may bring climate disasters such as nuclear winter, and secondly, covering nuclear bombs The cracks in space will be torn apart again, which is the experience gained in the defense of Nandu.
