This is the end of the third volume of "Under Deep Sky".

The "Centennial Plan" in the middle will be skipped directly and will not be written more, after all, no one likes to look at the stinky and long development time of several hundred years......

Anyway, no matter what core technology the alien life form "Black" gives and what kind of inspiration it will bring to mankind, there must still be a lot of engineering, and no point is missing.

So the whole project will definitely last a long time.

Well...... According to the current industrial capacity of the new human civilization, it will be developed for at least one or two hundred years.

Of course, there are still many things to write about, such as Yu Yifeng's specific negotiations with "Black", how to cultivate lizard natives, how to build spaceships, discuss the nature of the big filter, and some technological leaps, etc.

After all, the gap between low-level civilizations and interstellar civilizations is too big, too big to be incredible.

However, how to develop, the foreshadowing has been done, there is a lot of room for imagination, and it should not be too empty.

When the author writes here, he feels a little overused and can't breathe down.

In fact, my original intention for writing this book is, of course, these core ideas in the third volume.

I really hope that the "controlled nuclear fusion project" can be realized in my lifetime, and that my cranky ideas will not become a reality.

I also hope that these views can bring some inspiration and some food for thought. It's not like ordinary online articles, even if you've seen it and it's cool, you can't leave anything......

Of course, this book still can't get out of the category of online articles, and it is impossible to take the tragic route and abuse a few times like a physical book like Da Liu's "The Three-Body Problem", otherwise the subscription results of this book will definitely be even more spicy.

I don't like tragedy, and I don't like to write tragic stories, so I can only add some golden fingers to human beings, and write a lot of messy social system changes, etc., in an attempt to make this civilization break through the "big filter".

Although these contents are very serious and unpleasant, there is no way, they must be written, otherwise the story will only get stuck under the big filter.

Thinking about it later, even so, Goldfinger still doesn't seem to be strong enough, and it would be too boring if only the protagonist was left alone after breaking through to the interstellar civilization.

After thinking about it, I could only add an alien life form "Black", which was said to be a poisonous point; The Knicks civilization is added, and a bit of longevity technology is attached.

At that time, I thought that if the grades were too bad, it would be nice to end the third volume like this...... At least at this moment, people are still confident, anyway, whether they can break through or not is still two different things, and there are still a lot of variables.

I can't help it...... To be honest, humans are too weak. If you don't add a gold finger, you can't write it.

This big filter is my answer to Fermi's law, I don't know if you are satisfied?

No matter what, in the end, we still have to return to reality, life is indeed not beautiful, but it is not beautiful, we also have to face it.

The Earth is a speck of dust in the solar system, and the solar system is a speck of dust in the Milky Way. Our civilization is too weak, just a bacterium living on the dust.

Luckily, we have the sun, with an almost eternal solar energy, and we don't have to carry the miserable fate of the Knicks civilization.

Even if we are eternally low-level civilizations, at least because of the existence of the sun, we should ...... It's our good fortune to be able to live.

Probably so...... Actually, I don't know......

Scientist Stephen Hawking said: "Without escaping this fragile planet, I think humanity has less than 1,000 years left to live." ”

Everyone treats it as a joke, and even reprints it in the media, mostly to attract attention. Some people also fabricate rumors in the name of Hawking.

Anyway, it attracts eyeballs and always makes money.

But, who knows?

Maybe 1,000 years from now, people will take this sentence as the final prophecy?

Gamma rays in the universe may kill everyone in the next second?

Well, let's not talk about the heavy stuff.

Then there will be a side story, over the past few hundred years, about seven or eight chapters, and then the fourth volume will begin.

During the period, it may be the New Year, and the update speed may slow down, and I also have to sort out the outline later, after all, I decided to continue writing on the other hand, and it is easy to collapse without an outline in the back......

In the fourth volume, we will go straight to the interstellar journey and begin the journey to find the next "Earth".

The protagonists will also be looking for their next home.

Throughout the process, we will meet more civilizations, whether they are low-level civilizations or interstellar civilizations......

For various reasons, low-level civilizations are also abnormally strong, and interstellar civilizations are also abnormally weak.

Even...... There are also strange civilizations above the interstellar civilization that are difficult for humans to understand, and they just run away after making a joke with humans.

Playing tricks on interstellar civilizations became the fastest thing they could do.

Perhaps, we will also see a species that looks exactly like a human being, and even has almost no genetic material, living on another "earth", haunted by a large filter.

What will happen then?

Is it direct colonial occupation, or assimilation?

We will answer these questions in Volume 4......
