Tower Defense Strategy

In February, the situation on the ground continued to deteriorate.

　　 Human beings are throwing the last struggling power into space.

　　 Country C has sent more than 4,000 tons of effective materials and data into space in just over two months.

　　 4,000 tons is not too much, and it is not enough to build a bridge, but in the system of the launch vehicle in the atmosphere, this number is very terrible.

And half of the four thousand tons is used to supply the Moon Palace base, because the Moon Palace also needs the Moon Palace spacecraft and the Drought Transport System to change hands, which also incurs consumption. To complete this work, all electromagnetic silos have launch tasks every day to assemble the electromagnetic in the workshop. The launch vehicles lined up to be inspected.

　　 Due to fear that the time is not enough to complete the preliminary work on the ground, most of the materials arriving at the Moon Palace are parts and components, which require the Moon Palace crew to gradually complete the work with their own production capacity in the later period.

　　The most important part is the production device for lunar rover and earth-moon orbit transfer rocket.

　　 The technology of the rover is relatively simple and not important.

　　 Earth-moon transfer rocket has two models.

　　 One is the drought type C based on the improvement of the drought type B.

It is difficult to achieve explosive breakthroughs in technology in the short term. In order to achieve a higher level of application under the same technical basis, the dry ray C was not considered to be produced on the surface of the earth ball at the beginning of the design, which means that it does not have a reliable aerodynamic shape. The orbital speed can burn itself directly after being thrown into the atmosphere.

The weight of the 　　 Drought-C type surged from 30 tons to 45 tons, and the increase in thrust was very small, only increasing from 260 kN to 350 kN.

　　 The sacrifice is great, and the increase in specific impulse is obvious. According to the results of supercomputing simulation, its highest characteristic specific impulse can reach as much as 1500. By comparison, the theoretical maximum specific impulse of the hydrogen-oxygen dual-component engine is only 520.

　　 In addition, the relatively huge structure of the Drought-C type, fully considers heat dissipation, heat conduction and other issues. A manned cabin can be added to the front of the fuel section specially designed for it.

　　 But these things are still theoretical now, although I ran several times with several sets of super-computing physics simulation systems, the specifics would not be counted until the Moon Palace was actually built.

The 　　Hydrogen series does not have the ability to land on the moon. It can only be used for orbital transfer cargo between two satellites.

The other system used in conjunction is the lunar surface electromagnetic orbital projection device. With the projection device, the manned and cargo spacecraft no longer need the hydrogen-oxygen engine. The electric propulsion plasma engine is sufficient to achieve the task and can effectively serve the moon. Table saves water resources.

　　 Two sets of production chains, including the materials needed for the production of the monthly watch, are expected to take at least six to eight years to complete without affecting the main tasks of the monthly watch.

　　Considering that after the completion of the production chain, product quality is difficult to achieve in one step, country C has also paid a lot of money to directly invest two sets of dry and horrible B freight units on the orbit around the moon.

　　 The biggest problem with fission-based nuclear energy devices is that they cannot be completely stopped after starting.

　　 This statement is not very accurate. For the size of the nuclear power unit for aerospace, it is possible to completely stop the nuclear reaction halfway. The problem is that once it stops, the density of nuclear fission elements will decrease, which will cause the fuel rods to fail to restart. Therefore, as a backup system for Earth-to-Moon transfer, it is best that it has never been activated.

　　 Except for the part of country C, some of the things that can be produced on the surface, but the moon has nothing to do, such as rubber, plastic particles, etc., are delivered to the launchers of country R and ARE for delivery.

　　 Although the West Nakasu silo can be used, the efficiency of these guys is hard to count on, so they are mainly responsible for delivering cutting-edge products. Among them, the Moon Palace chip reserve planned earlier is also partly handed over to them.

Outside the Moon Palace, there is a set of important equipment, which is the supercomputer of the Kunpeng Space Station.

　　 Compared with the Moon Palace, the Kunpeng Space Station itself does not need to bear the burden of industrial production. At most, it has some internal crop cultivation and food processing businesses. The largest electricity expenditure is agriculture and daily lighting.

　　From the perspective of electricity, it is more suitable as a supercomputing platform, and it can also be regarded as a means of checks and balances.

　　 As for the future space station, because of the altitude of the orbit, I am afraid that it will not survive for long, but it has also prepared a bargaining chip for it, the atmospheric reentry device production capacity.

　　 This bargaining chip is not good. Once the moon watch is developed based on the resources of the moon, the small reentry device has no negotiating value.

　　 However, it takes time to build production capacity. The Moon Palace still has the launch problem of getting rid of weak gravity. With this bargaining chip, at least the personnel and data on the space station in the future will be rescued before the space station falls into the atmosphere.

　　 In early February, country C completed the launch mission of this phase ahead of schedule, and the space program entered a new phase.

　　 The third phase of the launch is mainly about various material reserves and personnel.

　　 There are no serious equipment in this part. They are all food, emergency tools, various metal ingots, high-purity rare earth element oxide powder, and animals with certain experimental properties.

　　 Needless to say, the purpose of the materials is, although the Moon Palace already has certain exploration and mining capabilities, it is far from full self-sufficiency.

According to estimates by professionals, even with the help of hundreds of Homo sapiens robots, it will take more than 40 years to build a full element collection and purification industrial capacity. If the moon palace human reproduction plan goes wrong, the fertility rate is much lower than expected. Pull longer.

　　 Space animal experiments are not new, this time it is a decision made after a lot of preliminary accumulation, space animal husbandry experiments.

Although 　　 is an experiment, it is very likely to become a swan song, so I made several preparations.

　　 In the space program of country C ten years ago, the main source of meat from the circulatory system is insects, especially those that can be used for breeding platycodons, bran and other leftovers, such as bread worms.

　　 The worm is very small, and the blood circulation and digestive system are less affected by gravity. A more obvious example, the blood circulation system of a worm only needs a valve, and there is no need to evolve into a form of separation of arteries and veins. This simple structure is easier to adapt to the space environment.

　　 Kunpeng Space Station is already raising insects.

　　 But in the long run, just a few kinds of bugs are likely to cause the development of civilization to turn in a direction that modern people cannot understand. In order to better simulate the life of the mother planet, the development of animal husbandry is essential.

　　 Of course, this is not a matter of deciding what to do. It must be based on scientific evidence.

　　Like insects, the smaller the animal, the lower the circulatory system is affected by gravity, and it is more likely to thrive smoothly under low gravity. Taking into account nutritional requirements, etc., the scope of screening is much smaller.

　　 There are three key items among the animals that will go to heaven in this round, namely rabbits, quail, and mice.

　　The common point of these three types is that the rabbit breed with short growth cycle, large reproduction number, and the longest growth period can reproduce in only two months.

　　 The three-animal plan will deliver more than a dozen breeds, and other relatively less important items will be placed in a much smaller number and category. For example, there are only three chickens in the plan and all eggs, and there are only two kinds of sheep, a total of eight.

　　The size of the sheep is no longer suitable for low-gravity long-term captive life, and it is very dependent on gravity during production. You can only try it at the Kunpeng Space Station, which has a higher maximum gravity. However, Kunpeng often has to stop and the survival rate is difficult to tell.

　　 At the same time, out of certain considerations, Country C relaxed the control of private refuge projects.

　　 Unlike country A, which did not manage it at the beginning, country C strictly restricts the construction of commercial refuges in order to ensure the deployment of labor and transportation capacity.

　　 A sense of security is the highest priority of human beings after they break away from animality. The formation of tribes and nations is the result of the pursuit of survival rate, and modernity is inevitable.

　　 Ordinary burrows can’t resist monsters, but as long as people feel safer because of this, building a shelter will become a rigid need, and doing things against the vast majority of rigid needs will definitely not last long.

　　 Country C’s approach is to ban it on the spot, while the grassroots make on-site decisions based on the situation.

　　 In the village, if someone digs a hole at their own expense, as long as they don’t use it for commercial purposes, the management will turn one eye and close one eye because there is not enough police force to repeatedly mediate and see-saw with the villagers.

　　Commercial companies also have a way. They don’t allow shelters to be built, and they don’t allow them to dig holes. They start with any project and build them slowly, and wait for the policy to be released before making project changes.

　　 It was not obvious the year before. After a period of deterioration last summer, the conclusion that industrial civilization will eventually be buried in the hands of monsters has been almost public. Competent companies have news channels, confirming that they will definitely release the management of commercial refuges, and various private real estate developers and construction companies have ended up.

After the launch of the third phase of the space system construction in February, a "Notice on Relaxing the Approval Process for Commercial Refuges" went down, and the market exploded instantly. Within a few days, there were overwhelming numbers of online and offline, electricity, and doorsteps. Refuge advertising and sales staff.

For the world, this "notification" from Country C is extremely bad news~www.wuxiaspot.com~ Since it has been blocked for two years, it has formed an effect similar to hunger marketing. When the news goes down, private production capacity will quickly go to refuge. The direction is concentrated, not only building materials, but also heavy equipment, furniture and electrical appliances, dehydrated food, etc. The related industry chain will absorb a lot of manpower and material resources in a short time.

　　 After this, any subjective adjustment of production capacity will become very difficult, and regions that have not yet taken the benefits of Country C will most likely be abandoned.

　　 Therefore, within a few hours after the notice was issued, it was immediately opposed by many countries.

　　 People who speak can only take up "The Art of Language" to deal with it.

　　 Of course, the senior management knows that the announcement at this time is tantamount to telling the world that it can’t stand it. But shouldn't the right of survival of our own people be lost? Do you really have to build a shelter until there are few deaths left in your family?

In fact, the biggest problem is that in the past two years, all actions of country C have not been coordinated except for a few countries. At most 10% of the global power is not dealing with monsters seriously. Most people!

　　 In the past two years, the global industrial chain has shrunk to the point of irreversibility, dozens of more than 500 industrial categories have fallen out of the chain, and the stock of combat troops in many regions has begun to fail to keep up.

　　 It's time to give up, at least leave a little time, and give my family a chance to survive.

　　 The internal cause of the change of direction cannot be stated clearly, the monsters should still be hit, but from the day the notification is sent, the goal is no longer to cross the galaxy civilization through the monster crisis, only time is left.
