Yu Hongxing's idea is bold and highly feasible, at least more realistic than building billions of fugitive spaceships in a short period of time, but it is also very difficult to implement. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info is not only a technical problem, but also a non-technical problem that cannot be solved by technology.

Transforming a planetary-level celestial body into an escape ship is a completely closed world to be precise, and although there are no insurmountable obstacles at the technical level, it takes enough time, a huge amount of work, and enough labor.

Obviously, the renovation project will certainly not be completed before the escape begins.

To put it simply, the transformed planet is actually a super escape spaceship, which can carry tens of thousands of passengers than the escape spaceship. If a planet with a diameter of 5,000 kilometers is used as a dwelling, the interior is completely hollowed out, and the surface area of the inner side of the shell is equivalent to the surface area of the planet, which can accommodate up to 10 billion inhabitants under the premise of satisfying the basic living environment.

It's just that just one planet is obviously not enough.

If it were just the Federation of Humans, a thousand of these planets would probably be needed. If you count the Polar Realm, you will need about 5,000 of these planets. If all the other civilizations in the Southern Alpha system were taken into account, at least 100,000 of these planets would be needed. Even if some civilizations don't have very high requirements for the survival environment, or can lower the survival requirements during the escape, they will need at least 50,000 of these planets.

Of course, 50,000 planets is not much.

In the Southern Alpha System, there are more than 10 billion planets with a diameter of about 5,000 kilometers and sufficient resources, and more than ninety percent of them have no permanent residents.

The problem is that transforming 50,000 planets is not much less than building a billion fugitive ships.

In other words, if you can transform 50,000 planets within a hundred years, you can also build a billion escape ships, and in terms of the probability of success, one billion escape ships must be much higher than 50,000 planets. If only to preserve the seeds of civilization, then escape ships should be built.

In fact, this is one of the main reasons why human scientists decided to build escape ships at the end of the Second Age.

Yu Hongxing proposed this plan only because the current situation was different from the end of the Second Age, at least there was no problem between the two camps.

Let's not forget that at the end of the Second Age, only a handful of human scientists advocated fleeing, and most of them placed their hopes on transstellar spacecraft based on central black holes. While the fugitive scientists were given opportunities, the resources available were extremely limited. What's more, no one at that time expected to be able to save everyone, only to preserve the seeds of civilization.

Obviously, the opposite is now true.

Although the war is not over yet, the war that has lasted for hundreds of years will soon be over after the Polar Realm entered the war as an ally of the Human Federation. Yang Yi's purpose is to save everyone, at least with this as the fundamental goal, and there is no other feasible means. As for the other method that Yang Yi personally searched, because it did not take up too many resources, it had an extremely limited impact on the escape operation.

It is precisely in this way that Yu Hongxing proposed this plan.

It's just that the problem is just as prominent.

Because it is impossible to complete the transformation work before the escape begins, Yu Hongxing proposed that the transformation of the planet be arranged after the start of the escape, and only the preliminary preparations need to be completed before that, such as setting up an industrial system for transformation services on the planet, and building an ecosystem based on the original energy that can provide a suitable living environment and working environment for all the inhabitants of the planet before the transformation is completed.

In addition, it is necessary to hoard resources that are indispensable for transformation on some planets and are not available on this planet.

Although this is also a huge project that requires a lot of resources, it is not worth mentioning the initial investment compared to the transformation of the planet. Not to mention the Extreme Realm, even the Human Federation can complete the preparation work before the transformation on the five thousand planets that meet its needs in about ten years. If it is the Polar Realm, it will only take twenty years at most to complete the preparation work on 50,000 planets.

Obviously, the preparation for transforming a planet is much less than building an escape ship.

Although this is only a preliminary preparation, not equal to the later transformation, and the amount of renovation is still very amazing, but according to Yu Hongxing's plan, the transformation will be carried out after the start of the escape, and at that time, I am afraid that no one will question the huge renovation project. Whether it is for themselves, their own nation, or other civilizations, everyone will go all out to participate in the transformation work.

Actually, there is a question at stake here, that is, the attitude of civilizations and the many individuals of each civilization towards flight.

This is undoubtedly the most serious problem.

In a sense, the Yu family's rejection of the plan to build an escape ship is directly related to this.

Even if the top and bottom of the Yu family, as well as Queen Kangsheng and other people in power of the Extreme Realm Clan, firmly believed in Yang Yi, they might not be able to convince others to believe Yang Yi's prophecy. As for the signs found by Yu Hongxing and other scientists, they are at most just signs, and they cannot be used to prove that a disaster is about to occur.

Obviously, this problem still exists in the preliminary preparations for the transformation of the planet.

To put it bluntly, it is not a trivial matter to build a complete industrial system on at least 50,000 planets and reserve enough supplies in advance. If there is enough time in peacetime, the problem is not very big, after all, both the Extreme Realm and the Human Federation have strong industrial productivity, can provide enough industrial products, and the resources are not too small. The problem is that the war is not over yet, and even after the war is over, it is necessary to carry out post-war reconstruction, and at this time, it is difficult to get the support of the people by allocating limited resources and industrial productivity to do things that have nothing to do with post-war reconstruction, and even cause the people to question and disagree with the authorities.

In fact, this is also the key to Yu Hongxing's belief that the transformation should be carried out after the escape begins.

To this end, Yu Hongxing proposed a more detailed plan, to be precise, a plan that clarifies the time node, but does not have specific content. To put it simply, it is best to be able to complete the preliminary preparation work within 50 years, and not more than 70 years at most, and the first 20 years should be dominated by technical preparation. After the completion of the post-war reconstruction of each civilization, the focus will be on the construction of the industrial system and the reserve of resources. The main purpose of this is to reduce the impact on the people in the early stage, so as to gain the recognition and support of the people. In addition, the technical research and subsequent infrastructure construction that followed partially overlapped with post-war reconstruction, which allowed post-war reconstruction to maintain secrecy, avoid premature knowledge of disasters to the public, and ensure the stability of civilizations.

It's just that if it is strictly carried out in accordance with the time node proposed by Yu Hongxing, it is indeed very difficult. Even if the time is relaxed to 70 years, it may not be possible to complete the preliminary preparations in time. As for the continued relaxation of the time limit, it is also unlikely, after all, there will be enough time to transfer the people of various civilizations to the fugitive planet. Thirty years is not enough time for the number of people to be transferred.

Of course, this is only difficult, and it is difficult to overcome.

In Yu Hongxing's words, as long as we make full use of post-war reconstruction, that is, take advantage of the special circumstances of post-war reconstruction to mobilize more resources and manpower, the problem of completing the preliminary preparations is not very large. For example, a comprehensive survey of the fugitive planets could be carried out in the name of post-war reconstruction. Since post-war reconstruction is the responsibility of the authorities, the duration of post-war reconstruction and the resources used are also determined by the authorities. Even if the public has doubts about this, it can be explained by post-war reconstruction, at least in the short term, without arousing popular disgust. Obviously, a few decades is not a long time compared to a war that has been going on for hundreds of years and has affected the entire Southern Alpha system.

Only, there is a problem that cannot be covered up with post-war reconstruction.

That is, at the beginning of the escape, the main sequence star of the star system where the fleeing planet is located must be destroyed, so that the fleeing planet can be freed from the gravitational constraints of the main sequence star. While it is theoretically possible to take this step only when the signs are sufficiently apparent or when it is already possible to prove that a catastrophe is imminent, it certainly precedes the catastrophe and certainly cannot be immediately justified by a reasonable explanation to the population. There is an interval of at least a few years, if not decades, between the beginning of the flight and the time of the disaster, during which the attitude of the population towards the flight, or the trust in those in power, can be decisive, and the situation can get out of control.

In addition, even if this interval is shortened as much as possible, it is impossible to avoid another problem, that is, the need to obtain enough fusion elements from the main sequence star before escaping will inevitably have an impact on the main sequence star, and may even lead to the complete destruction of the main sequence star.

Obviously, even Queen Kangsheng couldn't give a reasonable explanation to the people of the Extreme Realm.

Don't forget, back in the Second Age, all civilizations abandoned nuclear energy in favor of using it. Since then, all civilizations have built their scientific systems on primal energy. Although the war has caused great damage, no civilization has a reason to go back, let alone destroy the main-sequence star of a star system in order to obtain fusion raw materials that are widespread in the universe and are not of great value.

It can be said that this kind of retrogressive approach will inevitably arouse doubts among the public, and it may have unintended effects.

To put it simply, the period after the start of the exodus was the most dangerous.

As for how to get through this dangerous period, Yu Hongxing did not propose any way, after all, he is a scientist and is not responsible for solving troubles outside of science.

Of course, in the words of Yu Hongxing, after the escape began, especially after the disaster had been confirmed, all the problems were no longer a problem. All that needs to be faced is how to get as many people as possible alive to reach their destination alive during the long journey of escape.

For this reason, the Yu family gave a piece of evidence that was enough to convince Queen Kangsheng.
