Building a fully enclosed ecosystem is actually nothing at all, and it has long been proven in practice.

This is, the space debris that Xiao Wentian personally built, which has served as the base of the Yu family for more than 1000 years.

In order to gain the trust of Queen Kang Sheng, Yu Hongxing introduced the inner workings of this space debris in detail.

Of course, it doesn't mean that the technology used in this space debris can be used to transform the fugitive planet, at least the core technology can't be used.

In Yujia's space debris, all the energy comes from the original energy, and the space debris itself also relies on the original energy to maintain stability.Because this space debris can obtain enough original energy from the outside world in the southern Alpha galaxy, so it can exist stably for a long time.

Obviously, that's where the problem lies.

According to Yu Hongxing, now we can only be sure that if there is enough original energy in the star system, it will be able to obtain enough original energy.But outside the star system, there may not be enough original energy.At least according to the theory of original energy, in the vast universe outside the star system, the density of original energy is so low that it cannot be collected, so as long as it leaves the star system, the power equipment related to original energy will lose its value.Devices like the Primal Energy Converter don't work well outside star systems, at least in theory.In this regard, human scientists have confirmed it at the end of the second era, that is, the fleeing spaceships that sent humans and other civilizations to the Southern Alpha galaxy at that time carried the energy necessary for a deceleration, that is, the original crystal, and maintained the ecosystem of the escaped spaceships What is ordinary nuclear energy.This is also the case, the escaped spacecraft lost its use value after reaching the Southern Alpha galaxy and completing the deceleration.

Obviously, the energy required to slow down the fugitive planet must be much greater than the fugitive spaceship.

More importantly, it is impossible for the fleeing planet to be completely sealed, and a lot of energy will definitely leak during the tens of thousands of years of fleeing.

As for creating a suitable ecological environment inside the fugitive planet, as long as there is enough energy, it is not a problem.

You must know that the space debris in the Yu family has existed stably for thousands of years, and it can continue to exist stably if there is no external influence.In theory, the lifespan of this space debris is equivalent to that of the Southern Alpha galaxy, and it will exist until the Southern Alpha galaxy is destroyed.

That is to say, the Yu family has already mastered, or is able to obtain the technology needed to create a long-term stable ecosystem through research on space debris.

The prerequisite is that the energy supply must be guaranteed.

Because the original energy is unreliable, the only thing left is nuclear energy, and it is fusion nuclear energy.

Obviously, coming full circle, the problem comes back to energy.

Although the fusion nuclear raw material, i.e. hydrogen, is the most widespread existence in the universe, and the proportion of hydrogen in any star system exceeds 90.00%, but most of the hydrogen exists in the main sequence stars of the star system. The reserves on other celestial bodies are not sufficient.Even some huge giant planets contain no more than one percent of the hydrogen element in their star system.

Obviously, if you want to get enough light elements, you have to use the main sequence star.

As for the storage of hydrogen, the problem is not very big, a large enough space debris will do.If proper pre-processing is carried out, such as using a large enough pressure to allow the hydrogen element to exist in a solid state, enough hydrogen elements can be stored in the space storage device.

The real problem is that there is simply too much hydrogen required.

According to Yu Hongxing's calculation, if the destination of escape is a nearby star system, such as the Beta galaxy about 3 light-years away, then it will take [-] years for an escaped planet to accelerate, decelerate, and stabilize the ecosystem. The energy required is equivalent to the energy consumed by a yellow dwarf-level main-sequence star burning steadily for one billion years.Even if the acceleration is not considered, that is to use the original to accelerate the fugitive planet to the speed of light, it only reduces the energy consumption by about half, that is, the energy consumed by a yellow dwarf star that burns stably for [-] million years.What concept is this?This is equivalent to one percent of the total mass of an ordinary yellow dwarf star, and about millions of times the total mass of the escaped planet.If so much hydrogen is obtained from the main-sequence star in a relatively short period of time, the main-sequence star must collapse and be destroyed.

In fact, this is still the most ideal situation.

The conditions of the Beta galaxy are very bad. The central black hole accounts for 90.00% of the total mass of the entire star system. There are less than [-] million star systems that have been detected, and only less than one ten thousandth of the main sequence star has enough mass. , which can provide enough light and heat for the surrounding planets.In other words, even if they successfully reached the Beta galaxy, civilizations such as humans and the extreme race would not be able to settle here.

From the perspective of total resources, the ideal star system is the Sigma galaxy about 15 light-years away.

It's a star system similar to the Milky Way, with a central black hole, and about a billion other galaxies, many of which have main-sequence stars of reasonable mass.If they can reach the Sigma galaxy smoothly, humans and the extreme race may be able to find a suitable home here.

This assumes, of course, that conditions in the Sigma galaxy are exactly as observed.

Don't forget, the distance of 10 light years means that what is observed now is the scene of the Sigma galaxy [-] years ago.

Obviously, 10 years is too long.

This problem does not only exist in the Sigma galaxy, but also exists in all star systems.Simply put, no one can make an accurate judgment on the situation of the target star system based on the results observed now, even the nearest Beta galaxy.If the civilization in the target star system has developed and grown, has mastered the original energy, and even triggered an all-out war that can lead to the complete destruction of the star system, then after reaching the target star system, civilizations such as humans and extreme races will have to continue to flee .In this way, no one knows where the escape destination is, and it is impossible to know where to be, or when to end the escape journey.

Whether it is 3 years or 10 years, it is an optimistic and conservative estimate.

In addition, after reaching the target star system, the fleeing planet must be slowed down, at least part of the fleeing planet must be slowed down, so as to confirm whether the target star system is suitable for humans and the extreme race to stay and settle.In this way, the fugitive planet has to bring enough energy when it sets off.

In fact, when the destination of the escape cannot be determined, it is also impossible to determine how long the escape will last.

Although Yu Hongxing has made a guarantee that the fully enclosed ecosystem based on space debris can survive stably, as long as it is properly maintained, there will be no problem even if it is a billion years, let alone 10 years, but the longer it lasts , the more energy required.

Simply put, you must prepare for the worst.

The most ideal situation is naturally to bring a main-sequence star that can exist stably for billions of years, and use the original to accelerate the fugitive planet when setting off.

Obviously, the problem comes back again, that is, the main-sequence star of the star system where the escaped planet is located must be destroyed at the beginning of the escape.

This was not an easy decision, as it would mean the complete destruction of all celestial bodies in the star system except for the fugitive planets.

Destroy an entire star system for a planet?

Obviously, how to get people to accept it is a huge problem that cannot be solved by technology.

"Actually, this is also the main purpose of my coming here." Yu Minghui took over the topic and said, "It is impossible for us to wait until the disaster occurs before fleeing. A lot of work must be done in advance. Starting from the worst situation, we must at least It will take 30 years to transfer people and reserve energy for the escape during this period. In any case, it takes too much energy to accelerate the escape planet to the speed of light. Even if we have the sacred artifact provided by Yang Yi, we need to start it in advance. It may be possible in a short period of time, for example, to allow the fugitive planet to reach the speed of light before it flies out of the star system where it is located. In this way, we will inevitably destroy the main sequence star of the star system where the fugitive planet is located before that.”

Queen Kang Sheng nodded, expressing that she understood what Yu Minghui meant.

"My opinion is that the Human Federation and the Extreme Realm Clan can't get too close." Yu Minghui didn't make any more detours. "Although we are allies now, and this relationship will be maintained until the end of the war. Although under the command of Yang Yi, all civilizations in the Southern Alpha Galaxy, including the Human Federation and the Extreme Race, will be unified, but with Judging from the current situation, it is not necessary for the time being.”

"You mean..."

"Simply put, many problems can be solved by maintaining a state of war through confrontation. For example, the centralization of power can be strengthened through the war mechanism to ensure that various projects around escape can be carried out smoothly. Of course, I can use the need for war as an excuse to explain those that cannot be explained. things."

Queen Kang Sheng was slightly taken aback, her brows were locked together.

"Of course, this is only a state of war on the surface. In private, we will maintain exchanges in the field of science and technology and share all the scientific research results we have obtained. It is just that exchanges in other areas must be restricted, at least not to make the public think that those in power are doing it for their own interests. In order to ensure that the distribution of resources is as fair as possible, that is, to ensure that we all have enough resources to allow us and those civilizations attached to us to complete the preparations for escape, we need to redefine our sphere of influence before the end of the war .As for the specific division method, we can negotiate with the personnel we arrange, and generally ensure that the civilization and resources in their respective spheres of influence are proportional."

"The problem is, it's not going to last."

"We don't plan to keep it for long, after all, we only have 100 years."

Queen Kang Sheng let out a long breath and said, "In other words, we only need to maintain the confrontation for the next 100 years. After the escape begins..."

"Actually, choosing to escape is only the worst outcome." Yu Minghui paused for a moment before saying, "If Yang Yi succeeds, we don't need to take this step. The things we are discussing now are actually temporary. It is determined. What should be done will not be confirmed until Yang Yi returns. In any case, our purpose is to escape the coming disaster and fight for our common future."
