"Nuwa, can you predict how good the finished product we imitated after it is? How much thrust can it be? How fast?"

Nuwa just hesitated for a second or two and answered directly: "Your question is a bit difficult to answer, because we can't just build one propeller."

I realized that my problem was really stupid after hearing Nuwa's words. It was like when humans invented the internal combustion engine, they first divided it into two types: diesel engine and gasoline engine. Then, according to different power needs, each engine has different performance characteristics. Some have higher speeds, some have high torque, and of course, some have some super engines that surpass other engines in all aspects. Therefore, it is actually stupid to simply ask how much power the engine has, because there is no model that can't be determined.

"Sorry, I didn't think it through. Then you should have classified our thrusters. I just want to know which one will be installed on the immigration ship and our warship?"

"Your question is still incomplete, but I probably understand what you want to know. The specific thruster model is probably like this. According to the characteristics of the ultra-electromagnetic thruster, I will cross-categorize it.

First, according to the different users, it is divided into two categories: military and civilian types. Civilian types only require stable thrust and economical energy consumption. Military types can relax energy restrictions on the basis of civilian types to obtain explosive power and instantaneous change of direction. Of course, this has special requirements for the overall structure and manufacturing materials. In addition, according to different usage requirements, I will also classify the ultra-electromagnetic thrusters in a horizontal manner, name them type A and β. A type ultra-electromagnetic thrusters are mainly used in large ships, such as immigration ships or large warships. This model requires strong output power and ultra-long endurance. In addition, the β type will be used for attack fighters and traffic boats, which are dedicated to small ships. Compared with the type A, the β type requires a higher thrust-to-weight ratio, and also requires explosive power and instantaneous response capabilities, but the requirements for endurance can be reduced."

I nodded and said, "This classification is really good, so what level of performance can their performance reach?"

"In terms of thrust alone, the strongest one should be the thrust equipped for our escort carrier, which will be reasonably designed according to the optimal performance. I expect that the thrust of a single thrust should reach about 2.8 billion tons. With the volume of the escort carrier, thirty-six to thirty-eight thrusts may be installed. In addition, there may be hundreds of auxiliary thrusts with thrusts of about three to five tons. As for the maximum speed, this does not make any practical sense. If necessary, the speed of the escort carrier and the immigration ship can easily exceed one-fifth of the speed of light, or even reach one-quarter of the speed of light. However, given the detection technology and computer response capabilities we currently have, the most thing we do is to keep the spacecraft at one-tenth of the speed of light, which is the limit. After all, the universe is not flat, and it is too fast, we can't hide at all. However, given the detection technology we currently have, the most thing we have to do is to keep the spacecraft at one-tenth of the speed of light. After all, the universe is not a flat land, and it is too fast to avoid it.

Avoid obstacles in front. Small sizes can also rely on protective covers and armor to resist, but it will be troublesome if we encounter a planet. So after we imitate this thruster, the limit of our speed is not the power of the thruster, but our detection technology. As for small aircraft, there is no question of speed. Fighters need to fight in air, and the speed is too fast, the pilot cannot react at all. Besides, the body cannot withstand that terrifying G-force. Even if we use our dragon clan's physical fitness, the maximum G-force is only more than 10,000. No matter how large we are, we will still be fucked. So the speed of a small aircraft is not about how many pieces it can fly, but how fast you dare to drive. If we use a super electromagnetic thruster to create a missile, we can even accelerate it to infinitely close to the speed of light when the energy and acceleration distance are sufficient, but what's the use?"

What Nuwa said makes sense. The principle of the super electromagnetic thruster is not the same as the rocket thrusters that are well-known to ordinary people now. Under the premise that a rocket thruster is constant, its acceleration ability will gradually decrease with the continuous increase of its own speed. This is also the reason why human aircraft usually cannot fly too fast, because once the speed reaches a certain standard, the rocket thruster will be reduced to an almost negligible level. In this state, how can you say it is possible to accelerate?

However, the ultra-electromagnetic thruster is different from the rocket propeller. Its working principle determines that as long as there is space nearby, it can obtain stable thrust. Although this thrust will decrease with the increase of speed like a rocket propeller, it can theoretically accelerate itself to the speed of light. In fact, considering various losses and some physical variables, it can actually only approach the speed of light infinitely, but can never reach the speed of light. However, even so, the speed of the ultra-electromagnetic thruster is much faster than that of the rocket. Considering our current poor long-range detection ability, what limits our flight speed will no longer be the performance of the thruster, but the performance of the detector. After all, in the universe, it is impossible to confirm in advance whether there are obstacles in the hand-playing team in front, it is equivalent to a dog flying blindly with his eyes closed, and he knows whether he will suddenly bump into something.

"Nuwa, if we can increase the spacecraft to one-fifth of the speed of light, how much time can we save?"

"About six months." Nuwa replied with certainty: "If we cannot achieve other breakthroughs during this period, relying solely on the performance of the thruster, we can stay on the earth for another six months before setting off. This period should be enough for us to build a few more spacecraft and should be able to save 120 million more people."

"One hundred and twenty million people in six months, and twenty million people in a month!" Wina sighed, "It would be great if we could buy more time. It would be better to give us a few more years. Then we can take everyone in the country."

"Actually, we have a way to take everyone in the whole country away. It's a pity... forget it. It's better not to mention it." Nuwa suddenly sighed and wiped out the good mood we had just had just saved 120 million people.

In fact, we all know the method Nuwa said, that is, the whole world unites and then announces the secret of the world's last days.

The theoretical plan for this ideal plan is like this. First, countries around the world join forces to form a unified government government and concentrate global resources and strength. First, they save internal friction caused by stuttering each other, and second, they can also avoid unnecessary losses caused by repeated research and repeated reserves. For example, the project of preserving Earth species. Because now, except for the EU agreeing to the plan to share spacecraft, all countries are doing their own things, so every country capable of immigration must preserve animal standards themselves like the story of Noah's boat. It must preserve various animal world plant samples from the world and bring them to the alien planet. This project is not every kind of action that everyone thinks

It is enough to keep a species with one male and one female. Even if you use artificial means to help them expand their ethnic groups, it is not enough to keep two people. Besides, the time we have been delayed on the road is not a day or two, not a year or two, but hundreds of years. How should those animals be preserved during this process? Let them reproduce? Or cool down? So, these species preservation plans actually occupy more space than immigration itself. If you don’t need to take all these species away, just use spaceships to rush you personally, even if we can’t take everyone away before the disaster breaks out, we can at least send 80% of the Chinese people out. What is the case with this?

Because everyone is in charge of their own affairs, China needs to implement the species preservation plan, the United States has to do the same thing, Japan needs one, and the European Union has to do it, of course Russia is indispensable, and then there are second- and third-tier countries like Australia and Brazil, they have to do it. Even if they only retain some five types of them, this project will definitely make them bald.

But if everyone joins the government and then emigrates together, it will be much easier. As long as the whole world works together to create a set of biological samples, it will be OK. Well, how many places can you leave to hit people?

In fact, the species preservation plan is only one of the factors. There are many things that can affect the number of immigrants, but one thing is certain. As long as everyone joins together, there are many benefits. The question is - is it possible?

You asked the Chinese president to say to the US president: "You America start listening to us today, we can only know." What do you think Americans will do? The situation is the same. Even if you form a coalition government and everyone will have a joint meeting for a while, the situation will not be much better. The United Nations is the best proof. There are countless meetings held every day, and it is normal for a few months to quarrel on a topic. This is only half the time. When encountering major events such as the future of the country and the survival of the people, who do you think will make anyone? Therefore, uniting governments of various countries can only be empty talk.

Perhaps some people may say that it is the last day of the world. Can't everyone take a step back and work together? Yes, it's not possible, because the people who determine the destiny of the country are never the people who occupy the subject of the national community, but always the leadership class. No matter what a country is, the only one who determines the direction of the country will always be a few people. It has nothing to do with human morality but the law of physics. Because you can't let humans unify their thinking, so if a country unites and moves forward, it can only be a minority leader. Otherwise, it will be like a group of boatmen pulling boats in different directions. No matter how many people there are, the boats will not leave, because all the forces offset each other. So since the leading country is a minority, as long as this country has the ability to immigrate, the position of these leadership will inevitably be missing. After all, whether from the perspective of human selfishness or the importance of the overall situation, giving priority to the highest leadership of the country is an inevitable result.

So since leaders are destined to leave, why do they have to bring a few more people to sacrifice their leadership? Anyway, these countries are not able to take away a few percent of their population. Now everyone can basically guarantee that nearly half of their country's immigration rate. In this case, sacrificing their other half or bringing them with them is of little significance to the national strength itself. So why do leaders work hard for these people in this case?

Therefore, state integration is simply impossible. It is indeed possible to establish a joint government on Earth, but it must be done through bloody wars or gentle national integration. No matter which method, it will take a long time, and we just don’t have time now.

Among the things that Nuwa sighed, in addition to the beautiful and effective but never possible plan of establishing the Earth United Government, the beautiful and effective plan, there is another way to announce the news of the doomsday.

The core of this idea is that first, the news of the doomsday is announced, and then all entertainment and unnecessary production consumption are stopped. People all over the world concentrate their efforts to prepare immigration projects. If everyone works together, even if they cannot send all the population away, it will be no problem to transport them.

But just like the United Government plan, this plan is actually even more unreliable. You can never imagine how complex human thoughts are. Once the news of the disaster is announced, the social order of various countries will collapse at the first time, and the world will fall into a state of complete paralysis. In this case, let alone sending some people away, it is estimated that even the current shipping volume cannot be guaranteed.

Although there is no possibility of realization at all, theoretically speaking, if all humans on earth can really establish a coalition government and completely stop unnecessary consumption and concentrated their efforts to create immigration spacecraft, then it can ensure that the earthlings are 100% immigrated, what a wonderful result! Unfortunately, it can only be a dream, because human thoughts have never agreed, so now we can only watch helplessly as nearly two-thirds of the people on earth are left on earth waiting for death.

Forget it, I also know that this matter is not reliable, so don’t be sad. Nuwa saw that we were in a bad mood, so she ended the topic.

Next, Nuwa began to introduce to us various items and technical analysis that we brought back this time. Of course, she meant to help us divert our attention, but we didn't actually care too much. We only felt regretful and not painful about being unable to take everyone away. After all, our relatives and friends can participate in immigration, and the dead are people we don't know or are not familiar with. Secondly, we are not humans themselves, and even races are different. It would be great to worry about them. If we are heartbroken, it would be too fake.

In Nuwa's introduction, we finally learned about everything we brought back. In addition to promoting its technology and super killer star destroyer, we actually gained a lot this time. We also found a lot of things in the alien residential area that we thought would not have any value. Many of them were later identified as real civilian technology, which was basically not helpful to immigration, but there were also some useful technologies. For example, an unknown device we brought back at that time was eventually analyzed as an inter-star communicator.

Communicators are usually the most easily damaged equipment because of the existence of transceiver antennas. The non-traumatic communication equipment of aliens is basically done, so we have never figured out how aliens communicate, but we didn’t expect that this time we would find interstellar communicators among residents. You must know that finding such things in residents is basically more rare than finding military satellite phones at someone’s home. You must know that conventional communications have general equipment, so who would have nothing to do with a large satellite phone?

Although we only had this communication machine that no longer had energy, it at least showed us the working principle and general working method of alien communication equipment. That is to say, she has actually pointed out the research direction for us. With this guidance, we can move directly towards our goal, which is much easier than blindly looking for ways to communicate between stars.
