Yuriko thought for a long time this time before she spoke: "This report is all conceptual things, and the content is relatively novel, but the important points are missing, and it can only be seen as fresh." For us, there is nothing particularly worth referring to. ”

"We're unlikely to encounter more low-level civilizations until we gain interstellar navigation capabilities, so ......"

Yu Yifeng nodded in agreement. What kind of "spirit level" Yunyun, it sounds very mysterious, it's not bad to fool a child like Zhang Peng, but it's not enough to fool Yu Yifeng and others.

Actually, the "Spirit Level" is not much different from the "Race Value" in some games.

It is not of great use to the development of human society, can it still give people a three, six, nine and so on? Moreover, there is no numerical calculation in the report, and it is not clear what will be the case for a high score and what will be deducted......

"But if we can think beyond the content of this report, we will draw more conclusions."

"Let's assume that the scoring system is exact and that the content is real, then ...... Why do more intelligent alien civilizations come up with such a whole system to judge low-level civilizations? Yuriko asked.

Why a grading system?

Faced with this problem, Yu Yifeng felt a little inexplicable.

Alien things please, who knows they think so. Maybe it's just that they eat too much, and can humans still guess what they think?

Still, he listened patiently.

There must be a reason why Yuriko says this.

"I'm wondering, are there many low-level civilizations...... If civilizations are very rare, it seems that there is no need to go to great lengths to design a whole set of ratings, right? Obviously, the thinking contained in this scoring system is still very rigorous, and it should have taken a lot of effort. ”

She said this, and her tone was a little low: "I mean: since the universal laws of life are likely to be true in this universe, then ...... Is wisdom and civilization also universal? ”

"As long as it is a planetary environment that can evolve large creatures, is there a high probability that intelligent civilizations will appear?"

"If intelligent civilization is also universal, the value of this scoring system will be even higher. Because it can judge the potential of low-level civilizations more quickly......"

"What if...... Intelligent civilization is a rare existence, and this scoring system doesn't seem to be useful, right? It is rare, and it represents high value in itself! ”

This was something that Yu Yifeng didn't expect. When he heard this, his brow furrowed, and he fell into deep thought.

What Yuriko said was all hypothetical, without any basis, and it was completely divergent thinking. But overall, this analysis is quite interesting.

From this scoring system, I think of ...... In this universe, is intelligent civilization universal?

If civilization is universal, a scoring system is certainly of greater value. If civilization is rare, what's the point of doing this kind of scoring?

Not really...... Although diamonds on the earth are rare, there are also three, six, nine and so on. Although jadeite agate is rare, there are also various types of seeds.

Neither is it right...... The rarity of diamonds and jadeite and the "rarity" of the universe are two different concepts......

The cosmic-level "rare" must be at least one in 100 million!

One billionth of a billion here is measured in stars, that is, 100 million stars including their planets, before an intelligent civilization emerges, whether it is low or high.

That's what it's called a real rarity! It is completely incomparable to the diamonds of the rotten street.

And the "universal" in the universe does not mean that a planetary system has the density of a civilization.

There are hundreds of billions of stars in the Milky Way! The whole number is like a carp crossing a river, even if there is a civilization among the 10,000 planetary systems, it is too much...... It's also universal!

Thinking about it this way, Yuriko makes sense!

If a low-level civilization is very rare, and the interstellar civilization is very lucky to encounter it, it is completely possible to study and observe it slowly, rather than engaging in a set of programmed things to judge...... It can be seen that low-level civilization should not be a very rare thing......

At least not rare!

Yu Yifeng was deeply entangled, he wasn't sure if this idea was correct...... In fact, it's just a guess without evidence.

He had thought about this kind of thing, but he didn't want to think about it.

Seems...... Face the biggest fear in the world!

This kind of fear is not the fear of personal life and death, nor the fear of danger, but the fear of the quiet universe and the brilliant galaxy, and the fear of Fermi's law that makes everyone puzzled and difficult to break!

It comes from a deep concern for the future of the entire new human civilization!

If civilization is universal, it really is the worst and worst result for humanity, and there is nothing worse than it!

If civilization is universal, why are interstellar civilizations scarce?

Now, people have come into contact with the green light civilization, which is a real interstellar civilization, but the two sides have not fought, indicating that the universe is not a complete dark forest.

Since it's not because of the Dark Forest, it's not because of anything else...... What would that be?

The answer is on the verge of saying: the Great Filter of Life!

Is there an insurmountable life filter that stands in front of countless low-level civilizations, filtering out almost all civilizations?

Because of this great filter of life, almost all low-level civilizations are trapped on their own planets, and they don't get along with each other?

Is it still waiting for humanity in front of it, quietly waiting for people to approach?

After people approached, they were directly hit with a stick, completely shattering the backbone of human beings, so that human beings could never get up again?!

The bleak starry sky, how silent, there is no **silky fantasy, only bloody facts.

If that's the case, what should people do?

This is a question that Yu Yifeng and others don't want to think about, but have to think deeply.

Human beings, who claim to be the "spirits of all things", are just the spirits of all things on the earth, and what are they on the scale of the universe? Even the most conceited people dare not say that human beings are the most intelligent species in the universe.

So...... How can human beings want to cross the insurmountable life filter of countless races and challenge the inhumane probability of one in a billion?

Could it be that humanity is smarter, braver, and more united than any other race?

This is a question from the entire universe, and it is also Yu Yifeng's own question.

What is the Life Filter? I don't know!

What will humanity face? I don't know!

Yu Yifeng looked straight at Yuriko and found that she was also staring at him, looking flustered. It was rare for this girl to show such a dazed and overwhelmed expression.

This kind of looking at each other is completely the subconscious huddle of human beings to keep warm......

It's an endless chill from the universe......

It's not just the chill of falling into an ice hole, but another kind of confusion, confusion about the future......

He moved his throat, his Adam's apple stirred, and he wanted to say "All this is just a hypothesis, not necessarily true." ”

But suddenly he can't speak, it's like running away.

"We will become the ...... of interstellar civilizations," he said with difficulty to his feet, and said in a hoarse voice, "It will be!" ”

When I said this, it was as if I had used up all my strength. This is not empty words, he secretly vowed in his heart that he will work harder to shape the new human civilization into a stronger place.
