Tower Defense Strategy

According to the brief record of the battle log obtained from the alien octopus, the Level 3 monster will face the Green Mist monster not long after it comes out.

　　 Combat log brief record Country C got all together a year ago, but the third-level monster came out to confirm that the in-game base corresponding to the octopus is the singularity. The already destroyed Xinxin-3 satellite is just a scapegoat.

　　 It was a bit late to find out at this time, but even if it was discovered earlier, it just made everyone more pessimistic.

　　 It can be basically confirmed that if the monster crisis is not interrupted abnormally, the green mist monster will only appear sooner or later.

　　 The frequent appearance of the Green Mist Monster is the real end of the world for the earth ball. Although some high-energy weapons have been developed, they are limited by global energy supply and cannot form an effective defense at all. Even nuclear bombs are not that effective.

　　...In fact, there is no need to wait for the Green Mist Monster. If the third-level phantom successfully escapes several times, the earthball industry chain will basically be over.

　　 In the face of monsters like the Dimension Worm, two-thirds of the world is completely undefended and lacks effective guidance by air units. The strike methods of intercontinental missiles and space-based weapons are almost impossible to kill directly.

　　 The remaining one-third of the area has to take a desperate posture to pull some people to die with it.

　　 The possibility of getting through the monster crisis is very slim.

　　 Out of this judgment, at the same time that the three-level phantom was on the scene, the industrial chain of country C began to fine-tune.

　　 In early April, a new weapon production line was secretly launched.

　　 This is a workshop that produces electromagnetic rifles. It is not planned to equip the front line. The products will be supplied to some qualified refuge bases under construction.

　　Electromagnetic weapons have been attacking and off-loading models earlier. They are used underground because they do not need to consider the increase in temperature and temperature loss caused by flying speed, and the technical difficulty is lower.

　　 made a round of comprehensive trade-offs, and finally adopted a semi-electromagnetic circuit.

The advantage of 　　 semi-electromagnetic is that it can use the initial kinetic energy endowed by gunpowder to achieve the actual combat speed with lower power loss and shorter coils. Disadvantages, of course, are gun smoke and temperature issues.

　　 Limited by technical strength, the first batch of finalized electromagnetic rifles, MEK25, had a firing speed of 2400 meters per second, and the gun weighed 15 kilograms, making it almost impossible to shoot in a standing position.

The caliber of the electromagnetic rifle is 8 mm, and the average density of small electromagnetic warheads is slightly lower. Even if the projectile is longer, it has no advantage. The kinetic energy within 200 meters is about five times that of the 7.62mm standard assault rifle. The armor-piercing warhead has the ability to penetrate armor Is 1.8 times.

　　 After being tested by foreign volunteer forces to deal with small monsters, when the density is not high, a squad equipped with electromagnetic rifles can strike a firepower similar to a regular firepower platoon, and it must be comparable to a platoon with heavy weapons.

　　Because it is a burst weapon, it will not work when facing a group of small monsters.

When MEK25 was developed, it was considered to provide equipment for the base and the final city circle. The battery pack in its power module can be removed and replaced with a specially designed gun cable directly. When the power is sufficient, the single-shot strike effect and the 12.7mm heavy machine gun almost.

　　 is not very powerful, weighing 15 kilograms, and it has no advantage over light machine guns. The reason why it was still made is still considering the issue of resources after the disaster.

　　 As we all know, the gunpowder used during the World War is mainly nitrocellulose, while modern gunpowder is part of the ammonia synthesis industry.

　　 Whether it is nitroglycerin plus cotton or ammonia synthesis, it is obviously difficult to maintain after the disaster.

12.7mm machine gun bullets, different types and weights between 120 and 140 grams, to knock out one bullet box (200 rounds) per minute, it will consume more than 20 kilograms of materials, of which 70% of the weight is gunpowder, primer, etc. Recycled content.

　　 Such a consumption, to meet the occasional defense and material search needs of a base, it will not take too long to store thousands of tons of ammunition.

The MEK25 is equipped with a completely different situation. The R&D department has even prepared the transformation plan. If the gunpowder reserve is exhausted, it will be directly changed to an all-electromagnetic gun. The initial speed will be reduced to 1400 meters per second, and the power will still be larger than that of the equal-caliber gunpowder rifle. The difficulty of recasting is much smaller.

　　 began production earlier than it, and there is also an electromagnetic gun for underground bases, BEK-B.

　　 In order to facilitate entry and exit in the underground base, it is made into a wheeled armed jeep, which has a smaller caliber than a tank electromagnetic gun, only 20 mm, and is designed to only deal with small monsters of the first level.

　　 Good luck and suitable terrain. About ten to twelve vehicles can solve one. The configuration is also based on twelve vehicles. Try to allocate two bases to some bases. If there is still production capacity by then, expand the reserve.

　　 As for the second-level monsters, you can't expect an enemy that the global armed forces can only barely die, can be killed by hundreds of people with conventional electromagnetic weapons, anyway, they will either wait to die or detonate nuclear weapons on the spot.

　　 Laser weapons are also available, which are not considered conventional equipment.

The laser is very severely affected by fog, sand and dust. To ensure that the products produced will be useful in the end, it is specially used to set up close points, such as the laser-triggered strike on the inside of the gate, which uses a small laser of less than one watt for induction. , When you encounter it, you can use a few megawatts or more than ten megawatts of lasers to use as a cutting machine.

　　 Particle flow weapon, there is no special model for the post-disaster era.

　　 The barriers to use and maintenance of this weapon are very high. After the disaster, it has become a small base, education will inevitably go backwards, and more equipment will not be available.

　　 Country C can still maintain a certain production order. Some areas have already escaped again because of the news that Level 3 Vision has opened up the gun battle mode.

　　 Everyone is trying to **** more supplies, and then find a way to hide.

　　 It cannot be said that they were wrong. In order to survive, human beings have done unspeakably cruel things.

　　 It just doesn’t help.

　　 Most of the second-level monsters have the so-called "Life Forbidden Zone." If there is not enough science and deep enough holes, the monsters will kill the living creatures in the bunker as long as they pass through the air.

　　 If you want to find the last chance of survival, you still have to rely on industry.

　　According to the research disclosed long ago, the three defense fortification level concrete layer below 500 meters underground can guarantee a sufficiently high survival rate.

This survival rate is not passing by once or twice without being discovered, but the chance of successfully reproducing offspring in the refuge. After all, once the earth ball is occupied by monsters, you can't expect those high-level monsters to pass by only once or twice, as time rolls forward. , The number will definitely tend to infinity.

　　And fortification grade concrete layer...

　　Concrete has a low threshold and a low ceiling in all industries. Not many regions pay attention to it. Country C once reached 75% of the world's total cement production.

　　 After the monster crisis, in order to deal with monsters and to build new commercial shelters, certain areas have restored concrete production capacity, but the increase in high-quality models is relatively limited and cannot meet the requirements of three defenses.

　　 Of course, even if the supply of high-quality concrete is insufficient, the effect is the same as long as the hole is dug deeper and two more layers are laid.

　　 But in this way, the concrete gaps in various places are even bigger, and a small group of a few people can't get it at all.

　　 So the best result of those who turned on the gun battle mode is to find a deep mountain and old cave to pray, and I don’t know that their gods don’t care about monsters.

　　 The time shifted to mid-April, and the third-level illusion reappeared, so that he could not die, and found the state of country A in the deep middle ocean, the Eve Islands.

　　 The archipelago is the closest point of support to the homeland where Country A rejects the enemy. Therefore, a series of military bases have been built here. It's not much worse than the Central Ocean Command, but it's not much worse.

　　 The focus is on this position. The strategic bombers of the local and mid-ocean headquarters can directly fly over to help.

　　 For the second time against the Dimension Worm, the first step for country A is to fight for time for tactical deployment. As for how to fight for... the pilots and the people of the archipelago are all bait.

　　 After a delay of almost four hours, half of the people on the islands were killed. The strategic bombers on both sides had arrived within the range of the air-launched nuclear missiles, and the operation started.

　　 This time, a five million-ton equivalent hydrogen bomb was used to explode.

If anyone on the earth ball has done a good job with a continuous explosion of nuclear bombs, country A recognizes it as second, and no one dares to recognize it as the first. Nearly two hundred nuclear bombs have been dropped in the nuclear test conducted in Dazhongyang, and there may not have been observed. To and undisclosed deep water experiments.

　　The focus of continuous hydrogen bombs is shock wave and shock wave echo~www.wuxiaspot.com~ followed by photothermal ablation.

　　 Although the destructive power of photothermal ablation is stronger, but for missiles in flight, the shock wave threatens a greater range and affects for a longer time.

　　 The echo is more complicated, so I won’t talk about it.

　　 In short, country A voted ten at a time and successfully detonated five. Considering the destructive power and radius of impact of the five million-ton nuclear bomb, this success rate is already quite high.

　　 The result... I don't know.

　　 After the mushroom cloud passed, the monsters were gone, all covered with thick volcanic ash—the local volcano was exploded together.

Different from the land, most of the volcano on the island is actually in the water. The rupture of the mountain body causes a large amount of lava to leak into the sea. The water vapor generated will also be heated by the remaining lava on the island and the island heated by the nuclear bomb. At one time, the volcanic ash was generally water vapor, but actually still contained a lot of black ash.

　　 There was no visibility, and no water mist moving with the monster. Before the volcano stopped, there was no way to confirm the nuclear explosion.

　　 It takes a process to relieve the pressure of underground lava. It is not clear whether it can stop for half a month. If the dimensional bug disappears since then, it will be dead.

　　 But even if it was really killed, it was not something to be happy about. Half of the military bases in the archipelago were shattered by a nuclear blast. Although there were not many dead people, the monsters would probably not be given a chance to rebuild.

　　 The failure of the bases in the islands meant that the Central Ocean Command was lonely overseas. Once the fight started, the nearest support party that could be found was actually Country C.

　　 would rather die like that!
