Tower Defense Strategy - Chapter 308

Since the beginning of the monster crisis, Tuqiu has defeated hundreds of first and second level monsters. If placed in a controllable environment, it would be a huge victory for the entire civilization.

　　 But fighting monsters is slightly different, and the actual situation is getting more and more serious.

　　According to data provided by relevant statistical agencies, as of the end of XX24, there were five second-level monsters in the world in a state of fleeing and committing crimes. There are signs that there may already be more than one monster nest on the ocean floor.

　　Countries in the Mid-Ocean area are trying to assist A and C in their search. Unfortunately, due to the problem of underwater combat capabilities, they have lost at least five submarines so far, and yet no credible conclusions have been drawn.

　　 Underwater combat, don’t talk about soil balls, even in the game, there is a big problem.

　　 As a liquid, water itself restrains high-speed objects almost like concrete.

　　 The underwater strike capabilities that humans master are limited to depth bombs, underwater nuclear explosions, torpedoes, and mines. There is no electromagnetic harpoon in the game.

　　 is not bad, the problem is that these methods are not good for small monsters.

　　 The sinking speed of the depth charge is too slow, and it is not a threat to the relatively petite monster;

　　 It is unrealistic to use nuclear explosions to completely eliminate small monsters. Although underwater nuclear explosions are powerful, their high threat radius is relatively poor.

　　The launch depth of conventional torpedoes is generally no more than 30 meters in water depth, and it can be launched even deeper. Performance and safety cannot be guaranteed. Under the condition of limited water depth, the strike efficiency can be imagined.

In fact, weapons are not the point. The point is that modern military submarines do not have underwater optical observation capabilities. Most of them still use old-fashioned sonar devices. They rely heavily on ears and cannot automatically simulate digital environment graphics. This leads to their combat methods must be similar to turn-based. The response method is not suitable for dealing with little monsters.

　　 The mine is slightly better, but it has no mobility.

　　 The Tuqiu people have also made efforts in this regard, and they have achieved results, but they have no influence.

　　 It is fruitful, because the earthball man has indeed built a submersible that can face the little monster directly under the water.

These submersibles are generally modified with tourist viewing submarines and scientific research submarines. Because of their smaller size, they do not require the high-strength enclosure of military submarines. They retain the possibility of installing optical observation windows and do not emphasize diving depth travel. Most submarines simply use acrylic (plexiglass) shells.

There are already successful models on the **** route. They are all fishing nets and torpedoes. The fishing nets are deliberately made into a structure that is easy to entangle the target. With the addition of underwater automatic inflatable buoys (built-in compressed air cylinders), they can forcibly pull small monsters. To a depth suitable for torpedo strikes.

　　 said that there is no influence, because everyone is still in the groping stage, the models developed in various regions are very different, and there is no mass production, and they are unable to fight in the dark sea.

　　 No light sea area, biologically refers to the area below one kilometer, and two hundred to one kilometer belongs to the biological low-light area. The demand for fighting monsters can be defined as no light below 80 meters, and the lamppost without strong light is basically a food delivery.

　　Lighting can solve the light problem. Visibility is affected by the turbidity of the sea, and some sea areas can meet the requirements of the combat visual range. The problem is that the weapon system will basically become visible at this depth.

　　 Now offshore maritime transport, in addition to the **** fleet, the largest defensive force comes from a large number of deployed mines.

　　Mine mines have little technical content. Like landmines, they are all weapons that will suffer from a single deployment. Some of them may become global hidden dangers after the anchor chain is corroded and drift away with ocean currents. However, in order to ensure the last point of global transportation capacity, they have to be deployed in large numbers.

　　 In this environment, the status of the monster combat submersible is very embarrassing.

　　 Either make it smaller and incorporate it into the **** fleet in the form of a lifeboat, acting as eyes underwater; or it is in the port, only responsible for emergency resistance after the mine net is touched by a monster.

　　 In fact, the **** formation is more willing to use unmanned reconnaissance submersibles and towed detection equipment, so it doesn’t hurt to lose. In terms of ports, most of the water depths a few kilometers outside the port are less than 30 meters, and the high-speed surface torpedo boats can do a better job!

　　 If the deep-water combat capability cannot be broken, the new submersible will not have a suitable battlefield positioning.

　　 However, there are serious contradictions in deep-water operations.

　　 Deep water means that it is impossible to realize real-time data exchange with the surface system. All information needs to be collected and processed by the boat itself. Such a requirement will inevitably lead to the enlargement of the submersible, which will obviously move closer to the existing military submarines.

　　 The most radical in this regard is the new enterprise invested by Lijiaji in Mala Strait, which adopts a dual-machine solution and uses optical fiber to directly connect a data station that moves on the surface of the water to obtain data link support.

　　Using the surface station to receive the information collected and processed by other surface ship towed or dropped sonar can effectively control the number of equipment and manpower requirements of the underwater main body.

But it’s useless. The optical fiber is very fragile. It cannot be fully synchronized with the waves and undercurrents, and the water and underwater movement cannot be fully synchronized. The hub responsible for dragging, dropping and recycling the optical fiber is constantly working. All kinds of toss have caused the team to change more than a dozen types of optical fibers/cables. There is no set of models that can survive the test of one hundred working hours.

After all, optical fibers all over the world belong to fixed facilities. No one has nothing to do to develop a resistant to repeated bending and stretching. Even if an optical fiber enterprise is invested on site, a new type of wire that is not available anywhere else, the final R&D expenses will be all They have to be shared among the subsequent combat submersibles, and the unit price doesn’t want to buy it without opening up.

All in all, after two years of tossing, in addition to the **** formation, it is now possible to **** the fleet to take the deep-sea route. The existing maritime transport is concentrated in the waters less than 60 meters deep. Only a few areas have to maintain greater than six due to poor environment. A mine field with a depth of ten meters.

At first glance, the water depth of 60 meters does not seem to be much different from the fish pond. In fact, in some places on the earth ball, the entire sea area does not reach this depth. The surrounding waters of a certain island country in the Yangtze River, and some areas of the Paradise Sea in Dameizhou, etc., face the coastal area of ​​the ocean from several kilometers to tens of kilometers, so the scope of freight activities is not small.

　　 Compared with two years ago, global shipping has shrunk by about 70%.

　　 has shrunk a lot. In fact, compared to the chaos when the Golden Canal accident just happened, everyone is doing a good job. If it weren’t for the reduced demand caused by more and more occupied areas, there would be more.

　　Compared with shipping, the fall of various places has brought more problems to the world.

　　The so-called fall, not only the government was beaten and collapsed by monsters, but also the inability of normal production caused by the breeding of humanized monsters.

For the former, the international armed rescue forces have been exhausted, and there is no way to quickly return order to more regions. Just because of this change, it is estimated that millions more will die at the hands of various criminals and new warlords this year. The number of new deaths due to hunger in the occupied areas will be exaggerated;

　　The latter has caused military pressure on the border in the surrounding areas. For places with insufficient industrialization, almost all of them have to be exhausted, and from time to time external support is required to withstand the proliferation of humanized monsters on the border.

　　Occupied area not only brought the burden of global rescue, but also affected the surrounding areas not only at the military level.

In order of influence, the country that has fallen into total collapse is ranked highest in Country E, but it still maintains basic official operations with one-third of the “clean” territory, and no matter how far the West Central Community is stretched next to it, It is also the world’s third-largest economy, which has an impact but is not fatal.

　　 is followed by Au, which has the greatest impact on the surrounding area in the occupied area.

　　 In addition to the capacity of the Arctic route for hundreds of days a year, Au and its surrounding island countries are the most important shipping routes around the Central Ocean.

　　 Au was ruined by the second-level monster for a few waves and the population shrank by half. The smaller island countries around it have no security at all, and those with a little economic strength will immigrate at all costs, even if they go to inland countries to wash dishes.

The loss of senior talents caused by this wave of population migration directly caused the transitional island chain from Central Continent to Southern Great Continent to completely collapse. By January XX25, there were only three ports that could refuel large freighters in the entire shipping chain. There is another one that should be included in the scope of Central Continent.

　　 There are many similar situations. A few percentage points in statistics, when converted into area, the occupied areas and the areas with negative impacts can account for nearly 30%.

　　 The rest is not intact, but it takes time for many things to affect the spread.

　　 Then there is the immigration problem caused by fear.

　　Under the premise that industry and agriculture have been greatly affected, the number of new jobs that can be generated is very limited, and the tide of immigration is even more difficult than that of refugees a few years ago.

　　 I mentioned earlier that immigrants from landlocked countries have brought them development opportunities. Actually limited by water resources, transportation conditions, and body mass, the total amount of migration is relatively limited, and a landlocked country can only have thousands to 100,000 people.

　　 More people are squeezing to the inland locations of the coastal countries of Central Continent.

　　Nakasu is known as the World Island. It has concentrated the majority of the world’s population. Influenced by military strength and industrial distribution, it has also become the last hopeful place for the monster crisis.

　　 Starting from strength, country A will not be weaker, but individual cognition will be different.

Country A considers itself to be a model and leader of global civilization, but in fact, the number of people killed by the guns killed every year, everyone can see that it is obviously more suitable for people who are fierce fighting, more “mortals”, and still think that this area of ​​Central Continent is influenced by ancient times. Areas where civilization is more affected should be safer.

　　 Even if further rational thinking is concerned, in terms of strategic depth, the world island is not comparable to a beautiful continent. If it reaches the stage of human survival, country A may not be able to continue the world island.

　　 So the islands all over the world and some places that cannot be kept in front of us~www.mtlnovel.com~Most people turn their eyes to Central Continent, and pose problems for all regions of Central Continent.

　　 It’s better for countries like C who don’t accept direct immigration. Although they will be scolded by foreigners, they won’t lose a piece of meat. However, it is true that illegal immigrants from many places have lost their repatriation conditions, and some arrangements must be made. It looks like a million people.

　　 Xizhongzhou is worse. If you are free, you will burn yourself.

　　According to incomplete statistics, in XX24, the number of new people who settled in Xizhongzhou through legal and illegal channels reached 10 million in a year. Some organizations claim that the actual number will rise by 20%.

The status of Xizhongzhou in modern history is unquestionable. It is the leading place of the industrial age, the birthplace of modern medical care and education, the birthplace of the two development routes, etc. However, no matter how it is blown, the whole Xizhongzhou is only an area. In regions where population, economic volume, and industrial production capacity are not as good as that of country C, a bunch of countries live together, which also causes a waste of additional administrative resources.

The pressure brought by 10 million new immigrants, coupled with the amount of industry lost by the monster attack in country G, directly reduced the quality of life of the people in the entire region, and the crime problem caused by lack of jobs has further intensified. situation.

　　From this perspective, the statistical figures summarized in XX24 before are a bit over-beautified.

　　 To be more serious, even if the monsters do nothing this year, the world will have to spend a lot of energy and countless resources to maintain the current situation without getting worse.

　　 Obviously, it is impossible for the monster to do nothing.
