Lu Yu's support played a decisive role in this proposal.

Human civilization has developed to the present day, and the promotion role of the Silver Star is self-evident.

What's more, with Lu Yu as a window, human beings have seen the vastness of the universe and seen so many civilizations.

If you rely on human beings to get to this point, you don't know how many twists and turns you have to go through to get to this point?

Just looking at the database of cosmic sociology, there are a large number of social data of civilizations, including more than 33,000 planetary-level civilizations and more than 300 stellar-level civilizations.

It's not something you just picked up.

If you really want to build up to the current scale of the database, without millions of years of civilization observation and exchange, it is simply impossible to obtain so many civilization observation samples.

And now, relying on Lu Yu's window, human beings can easily get them, and even know more about the civilizations in the universe than some stellar civilizations that have stepped into the starry sky for hundreds of thousands of years.

This is also reflected in a discipline.

If it is in basic science and cutting-edge technology, the dependence on Lu Yu is even more serious.

Whether it is the sample observation of space technology or the research of various technologies of the Zerg spacecraft, these major projects can only be realized by relying on the Silver Star.

From the perspective of cutting-edge scientific research, once Lu Yu is not used as a bridge, human scientific and technological research will almost instantly rewind by hundreds of years.

Therefore, it is not unreasonable for the system to judge that the Blue Star Human is a vassal of Lu Yu.

At this time, Lu Yu was the first to stand up and support the proposal, and it was impossible for anyone to ignore his decision just because he was still in deep space.

Instead, because he was in deep space, the Blue Star Humans had to pay more attention to any of his opinions.

So when Lu Yu stood up, this strategy seminar unanimously chose the proposal to pause.

But it does not mean that the deep space industry in full swing will be stopped, the current Great Wall of Space program has reached a critical period, and no one can stop the first stellar project bred by human science and technology.

........

"You said that if the humans of Blue Star were not threatened by the unknown fleet, would they be faster than they are now in the solar system?"

The Q version of the seventh version of the avatar popped up a dialog box: "If there is no pressure to survive, then human beings are probably still immersed in the construction of the Earth-Moon system, and many technologies will be slowly released due to various factors." ”

"The Lagrange Point Space City will be delayed by the overreaction of the entire human race, and the first spaceship will only arrive on Mars and return to the base ......"

Seven's analysis is not a fiction out of thin air, combined with the logical analysis of human thinking and terrifying computing power to construct a prediction of human behavior, it can only be said that big data may know itself better than itself.

But after the meeting was suspended, Lu Yu stayed in the virtual reality personal space, and instead of relaxing himself in various ways, he let Seven access the signal, and he looked back at the single-celled creatures found in the acid sea before.

In the virtual reality scene, Lu Yu seems to be standing on the dim and turbid sea of acid, and below him is a relatively clear sea, which is the sea where those tenacious single-celled life survive.

It's just that now this seemingly clear area is beginning to be eroded little by little by the surrounding turbid sea, because of the drastic changes in the environment, the pH value is rapidly decreasing, and these single-celled organisms in the acidic environment are dying in large numbers.

Only a small number of single-celled beings hid in the layers of corpses of their own family, barely dormant by thickened cells, and survived.

This scene reminded Lu Yu of his analysis of the ancient period of the Blue Star, the former environment of the Blue Star was not suitable for the survival of today's creatures.

Taking oxygen as an example, in today's nature, oxygen is not only widely distributed in the atmosphere, but also has the highest content of oxygen in the earth's crust, accounting for 48.6% of the earth's crust mass.

Nowadays, animals need oxygen for respiration, life reactions and all oxidation reactions, although a large amount of oxygen is consumed every day, the oxygen in the atmosphere will still remain at a relatively constant value, because the photosynthesis of plants is constantly adding oxygen to the atmosphere.

Therefore, the first impression of many human beings on oxygen must be that "life is inseparable from oxygen", because the breathing of life is to obtain oxygen in the air, and if there is a lack of oxygen, life will die from lack of oxygen.

However, for some life, oxygen is "poison", and these strange anaerobic creatures are an important reason why Blue Star can now develop a human civilization!

Long before Lu Yu stepped into the starry sky, anthropologists already had ample evidence that the oxygen content in the atmosphere of Blue Star was not high in ancient times.

And all this change starts with the birth of the first lives of Blue Star!

The earliest life on the blue star appeared about 4 billion years ago, and the current blue star is about 4.6 billion years old, and the oxygen content of the blue star's atmosphere began to gradually increase 2.6 billion years ago, which means that the early life on the blue star did not need oxygen!

The original life of the blue star was born in the depths of the ocean, they did not need oxygen, nor the heat of the sun, but relied on the "hot springs" in the depths of the ocean, the heat of these hot springs came from the lava seeping out of the blue star, and there were a large number of chemicals near these submarine hot springs, which created the first life of the blue star in such an environment.

The first life on the blue star were all prokaryotes with relatively simple structures, and they were all "anaerobic organisms" that did not need oxygen, for which oxygen was really "poison".

Archaea, probably the oldest form of life, can survive in a variety of extreme natural environments, from highly salty lake water to extremely hot, acidic and absolutely anaerobic environments, and even in extreme cold.

The preference for extreme environments by archaea, and the extreme anaerobic characteristics of some archaea, suggest that the humans who excavated this period of history later, these oldest lifeforms, went through a very difficult period to evolve these characteristics, which happens to be the same answer that anthropologists have obtained from the strata: the early blue star environment was harsh and extremely hypoxic.

Since there was no oxygen in the atmosphere of the early Blue Star, life at that time was anaerobic, for these creatures, oxygen was really "poison", but for the vast majority of life on the Blue Star now, oxygen is an indispensable necessity, and the statement that oxygen is a "chronic poison" is just grandstanding.

If there is no oxygen, the life on the blue star is still a simple archaea, how can it be possible to build a complex and diverse life system, and then in order to adapt to the environment and give birth to wisdom, and without wisdom, then the foundation of scientific and technological civilization no longer exists.

So, what happened to cause oxygen to start appearing in the atmosphere of the blue star?

The simplest and most direct reason is that there is a creature that has evolved a unique skill "photosynthesis", cyanobacteria are a primitive single-celled life, but this organism can photosynthesize, cyanobacteria do not have chlorophyll, but they can still carry out oxygen photosynthesis.

The emergence of cyanobacteria has allowed the blue star to develop from anaerobic and hypoxic to modern blue star with sufficient oxygen content, and the emergence of oxygen is one of the basic factors in the complication of life, as evidenced by the fact that eukaryotic life is generally larger than prokaryotic life.

In addition to cyanobacteria, there were also some environmental changes in the blue star at that time, there were a large number of "methane bacteria" in the ocean at that time, these bacteria would release methane in the process of metabolism, and the appearance of methane would inhibit the increase in reduced oxygen, and at the time of atmospheric oxidation events, these methane bacteria died on a large scale for unknown reasons, so not only cyanobacteria were releasing oxygen, but greenhouse gases were also relatively reduced, providing a more suitable basis for the increase of oxygen.

Without the emergence of life like cyanobacteria, and the coincidence of environmental changes, the Earth could become a second Venus, and the severe greenhouse effect has made the planet's environment extremely harsh, thus rejecting civilization before the first filter.

And the single-celled life in front of us, born in the sea of acid, could it be the life form that can change the fate of the entire planet?

Just like the blue-green algae of Blue Star, it took hundreds of millions of years and countless generations of life to change the entire planet.

Perhaps on this nameless planet, these single-celled lifeforms had worked hard for hundreds of millions of years before Lu Yu arrived, but it was clear that they were still far, far from succeeding.

It may take hundreds of millions of years, or it may not be enough for this planet to become a planet suitable for intelligent life until the star turns into a red giant.

Lu Yu looked at the layers of dead single-celled life, and when the turbid sea of acid eroded them, there was a surprising scene, and the turbid sea of acid became clear again.

"It's acid-base neutralization?"

"Can the corpses of those single-celled organisms secrete alkaline substances when exposed to strong acids?"

Data analysis in virtual reality made Lu Yu understand what was happening. But the more this happened, the more he couldn't help but ponder.

If we look at the universe, the environment of the universe is not suitable for civilization, but isn't civilization like cyanobacteria and these single-celled life forms struggling to survive in the universe?

So....... will one day, through the efforts of generations of civilizations, be able to transform the universe into an environment suitable for civilization to survive?

Like spirulina, like these single-celled life?

This answer, with the current Lu Yu, he can't get it, but if he can survive that long time, maybe he will have the opportunity to witness that moment, right?

"Civilization, civilization."

Lu Yu repeated it in a low voice for a few rounds, and finally withdrew from virtual reality.

Opening his eyes in reality, he lies on the soft grass with his head resting on Seven's lap.

Today's virtual reality headsets have been replaced for generations, and they can be connected to virtual reality by attaching thin-film electrodes to a few key points in the head.

Such a technology, before Lu Yu left Blue Star, he couldn't believe that there would be a day when it could be implemented.

Now, virtual reality technology has penetrated into all corners of human civilization, and new ideas are sprouting from it.

If it were placed in other civilizations, such new ideas would affect civilization for hundreds of years to come.

It's just a pity that such a new idea will soon be left behind because of the new round of productivity explosion.

Could it be that in the great universe, that is, the human civilization of the Blue Star, has enjoyed this kind of magical treatment, right?

As long as there is enough time, you can step into a stellar-level civilization without any obstacles, and even the big filter that a third-level civilization has to work hard to break through can be directly ignored.

"Is there any movement on the triangular spacecraft these days?"

Lu Yu still enjoyed the soft and smooth special pillow, and the skin of No. 7 was no different from that of a real person.

This kind of humanoid technology has been quite mature on Blue Star, Lu Yu once used virtual reality to see the street scenes of several emerging cities, and once thought that he had come to the set of a certain game.

And with the number seven here, human beings don't have to worry about the intellectual crisis that the third-level civilization is deeply afraid of.

"Again, it seems that the Rings are not going to use gravitational lensing, but to use more covert and efficient methods of space-related observations."

"Our understanding of space technology is really still blank, so we can only keep it as it is."

The original state is not to speak, pretending to be a master.

A pleasant voice sounded in his ears, and Lu Yu just shook his head helplessly.

As for the question of the concept of time, he had been prepared before.

Spending a month motionless here is probably just a short moment in life for the members of the Ring Clan, which is worse than a second in human feelings.

But for human beings, a month is equivalent to one thousandth of a life.

In the past, before Lu Yu left Blue Star, a person's lifespan was only a thousand months.

One in a thousand, compared to one second in other civilizations.

Time has a very different attitude towards creatures of different civilizations.

"Do you want to go back to the folding space?"

"At least you don't have to watch single-celled organisms multiply all the time, and you can earn some points by giving lessons to those super lifeforms!"

"I don't know how long it will take for this triangular spacecraft to end its observation, if it is the same as that lucky stellar civilization, come for a hundred years first........ then this mission is basically sent."

"Why don't you settle the [Exploration of the Starry Sky] first, collect enough points, repair the Silver Star, and find a way to return to the solar system before considering the task of the Ring Clan civilization?"

Lu Yu was thinking about whether to throw the triangular spaceship in his heart for a while, when he felt Seven's little hand soften in his solar system.

"What's wrong?"

Lu Yu opened his eyes again and asked, he knew that there was nothing wrong, and Number Seven would not bother him when he closed his eyes and recuperated, she just waited silently for him to wake up.

This is the tacit understanding that the two have gotten along with for many years.

"There's a message from the triangular spacecraft."

Seeing Lu Yu open her eyes, she continued: "Observe the target galaxy, the results are out!" ”
