The so-called operator is three spheres, three metal spheres stacked together, a total of nine, each three stacked into a group, the bottom sphere is about fifty centimeters in diameter, the upper one is about one meter in diameter, the top one is more than two meters in diameter, one is larger than the other.

After turning the stool around, the operator revealed his true face.

Each sphere is transparent, so it can be seen that inside each sphere there is a brain, nine brains, and every three brains make up an "operator".

The nine brains were soaked in a nutrient solution, and the spheres were covered with metal wires less than ten centimeters long, like antennas.

Chu Ci shuddered: "This is the biological brain?"

"Yes, three operators, nine biological brains, three small heads at the bottom, responsible for weapon systems, energy output, artillery systems, delivery transfer compartments and beast mechas, the three heads in the middle, responsible for energy conversion, starship flight trajectory, space jump calculation, etc., the top three heads, responsible for the internal operation of the starship, energy distribution and remote contact, according to the needs of the mission, you can also coordinate or change positions. ”

Qin Lele took out his mobile phone, shouted eggplant, and took a family photo of the nine heads soaked in the nutrient solution.

Chu Ci was speechless.

He found that even Qin Lele was a little out of tune now.

But this Western scenery is really weird, Hollywood doesn't have such a shot, at most it's just a brain.

"Just these three operators, relying on nine heads, control such a large starship?" Chu Ci still couldn't believe it, you must know that this starship is much bigger than a star beast, and it turns out that it relies on nine heads to operate, which is too... Save manpower.

Compared to the spaceships in Hollywood movies that can't be operated by thousands of people, this has to be a lot less work, and even if you don't pay your salary, you can't even go on strike with nine broken heads.

"The brain waves of these nine heads are connected to the starship's central system, which can receive and transmit three hundred and twelve instructions in one second, they themselves are part of the starship, although they have their own thoughts and free will, but they have no body, and their brains have been taken out from the moment they are born and installed on the starship to become a part of the starship. ”

Chu Ci discovered that everything that has anything to do with the Devonian has nothing to do with human rights, but everything that has anything to do with people has never been done in the Devonian.

He didn't know if the Devonian nobles had dogs, he just knew that these nobles were real dogs.

Having your brain taken out and thrown into a nutrient solution at birth, and then being an operator in a starship forever is a terrible thing to do.

Qin Lelexiu frowned slightly, and asked, "All starships are like this?"

"Of course not, this Blue Scorpion starship is not the first echelon of the battle sequence, the volume is not the largest, and the functions are not the most complete, it is completely enough to rely on three operators, most of the time it only needs to rely on the brains of the top three control centers. ”

"What was the Devonian population base?"

"Less than 100 million. ”

Qin Lele was stunned: "So little?"

"Less?"

Chu Ci finally found a sense of superiority, and said happily: "It's less than one-sixtieth of our earth." ”

"The number of people is not less or more is better, but it is most appropriate to meet the needs of sustainable development at different times, and the Devonian population is carefully calculated, and this number is the most appropriate for the whole civilization. ”

"How do you know that 100 million is just right?" Chu asked puzzledly: "There are more habitable planets in the entire universe, and the land is vast and sparsely populated, isn't that a waste of resources?" ”

Chu Ci still understands this.

The earth's population has ushered in explosive growth in recent decades, and as of now, the total population has exceeded 7.5 billion, and it is estimated that it will definitely exceed 8 billion in about ten years.

The total population continues to rise, resulting in the deterioration of the ecological environment and the shortage of resources, so to speak, the earth is already overcrowded, various energy crises and food crises are not uncommon, to control the rapid growth of the population, to maintain a certain population size, is also a consensus of people today.

But it's still a matter of technology, agriculture, industry, and the environment.

To feed so many people, it is necessary to ensure an adequate food supply.

But there are more people, there is more food, and the industrial ecological chain that supports human development also needs a large number of grassroots industrial workers, without them, the entire industrial system is bound to be paralyzed, unless human beings can achieve fully automated production, but the shortage of human resources will still restrict the development of artificial intelligence.

Agriculture needs people, industry needs people, and the environment.

The environment, which can also be said to be the sphere of human activity.

It doesn't work if there are too many people, and it doesn't work if there are fewer people.

If there are too many human beings, destroy the environment, if there are too few human beings, most of the land will become uninhabited, and the ecological environment will gradually restore to ancient times, when wild animals will regain a lot of living space, and human beings can only occupy a few prime locations because of limited manpower, huddle together for warmth, and jointly fight against the threat of other species on the earth.

From the beginning of the early Homo sapiens to the present, human beings are only more than 200,000 years old, until the seventh millennium BC, the world's population for the first time exceeded 10 million, in most of the following time the number of human population stayed at hundreds of millions of people, until the beginning of the industrial revolution, the population ushered in explosive growth, this growth on the one hand is to meet the needs of industrial development, on the other hand, it is also the result of human uncontrolled consumption of the earth's resources.

Therefore, the most appropriate population base of the earth depends entirely on the level of science and technology.

And the Devonian does not have this problem, no matter how the population explodes, there are too many places to go, since this is the case, why is it said that 100 million people is the best population base?

"Because the Devonian is only a second-level civilization, it has not yet created the ability to create energy celestial bodies out of thin air. ”

"What do you mean?"

Yan Entropy asked, "Do you know the Dyson sphere theory of your earth?"

Chu Ci, who didn't learn and didn't know how to do it, shook his head, but Qin Lele asked puzzledly: "What does it have to do with the Dyson sphere theory?"

The so-called Dyson sphere is a theory proposed by Freeman Dyson one of the earliest times, which roughly means that artificial celestial bodies are used to wrap around stars and exploit their energy.

In layman's terms, it is a natural nuclear fusion reactor that uses a star as a power source, such a "sphere" is composed of moons orbiting the sun, completely surrounding the star and obtaining most or all of its energy output.

"Everything on your earth, almost all related to the sun, the sun continues to radiate heat to the cosmic space every day, of which only one part of the energy of 2.2 billion radiates to the earth, becoming the main source of light and heat on your earth, the sun brings light and warmth to your earth human beings, and at the same time makes the earth produce day and night and seasonal alternation, balance the earth's climate, and provide various forms of energy for life on the earth, because of chlorophyll, most of the leaves of the earth's plants are green, and chlorophyll can only synthesize various substances by using the energy of sunlight, and all green plants on the earth can produce about 400 million tons of energy substances every day, such as proteinAt the same time, it can release nearly 500 million tons of oxygen into the air, providing sufficient conditions for the survival of humans and animals. ”

Qin Lele nodded thoughtfully, and Chu Ci asked, "Then what does this have to do with your population base and what Dyson sphere theory is?"

"One in two two billion, the solar radiation energy you passively obtain is only one in two two billion, every galaxy has stars like the sun, unlike your earth, our Devonian civilization has the technology to accelerate the acquisition of star energy, but it is only accelerated, understand?"

"I don't understand. ”

"It's like the oil of your earth, let me make an analogy, your earth should have ten tons of oil, and the normal mining rate is one, one ton a year, and it can be mined for ten years, but you have a scientific and technological device that can mine eight tons a year, and the price is a waste of two tons, now you understand?"

Chu Ci shook his head: "I still don't understand." ”

Qin Lele understood, and explained to Chu Ci: "Speaking of which, it is still a problem of waste of resources, the scientific and technological level of civilization in the Devonian has reached a bottleneck, the growth of the population base cannot improve the level of science and technology, and more people need to waste more resources, even if the universe is expanding, there are many stars in the cosmic wall, but after all, it is not infinite, the more people there are, the faster the resources in the cosmic wall will be used, and the more they will be wasted." ”

"Now I understand. Chu Ci nodded: "High-level civilization does not need oil, but energy, most of the energy comes from stars, and although the Devonian is a second-level civilization, it does not have the technology to create stars, that is, energy sources, so I don't want to increase the population and cause a waste of resources." ”

"That's right, that's what it means. Yan Entropy snapped his fingers: "The population I'm talking about has a body and a brain, not a freak like this who only has a biological brain and no body." ”

After finishing speaking, Yan Entropy pulled out the high-frequency knife on his shoulder and walked to the console with an expressionless face.

Stepping on the stool, from top to bottom, pierced the three brains on the far left.

After the transparent device shattered, the milky white nutrient solution inside flowed to the ground.

Yan Entropy jumped on the second stool again, and as he did, three more heads were pierced into rock sugar gourds.

Shaking off the viscous liquid on the high-frequency knife, Yan Entropy happily said to the only operator who was struggling: "I'll count to five, turn off the power supply, and call up the galaxy map for Lao Tzu, and call up the exclusive contact signal for the perfect body to wither." ”

The three heads were straight at Yan Entropy, and they didn't move.

Duanshu proposed: "Otherwise, the Natal hacked them, it's just a brain, most of them are still programs, and they are probably not afraid of death, you can't take them out and beat them, they can't survive without the nutrient solution." ”

"It's not the first time I've encountered this kind of cheap bone, look at me. ”

Flame Entropy has a high whip leg, and the force is controlled very high, kicking down the transparent circular device containing the largest brain on the top.

It can be seen that the three transparent circular devices are not connected by some kind of object, but by magnetic force.

Yan Entropy squatted on the ground, smiled, and took out thermite from his back butt pocket.

A portion of the aluminum powder in the thermite bomb was poured out, and after igniting, Entropy placed the metal transparency device on it.

Looking at the ignited aluminum powder, Chu Ci and Qin Lele glanced at each other and found that Yan Entropy was really a beast.

"Charcoal-grilled big heads. Yan Entropy laughed and stepped aside.

I saw that the nutrient solution in the transparent device was like boiling a pot, bubbling, the brain inside was squirming at an accelerated pace, and soon it changed color, and the peristalsis became faster and faster, although it couldn't make a sound, but this scene still made Chu Ci and Qin Lele a little physiologically uncomfortable.

It's a ridiculous feeling, and they don't even know if they should call these biological brains living beings.

If you want to say that it is an object, the brain is alive, and at least some of the emotions can feel part of the perception, but if you want to say that it is a living body, they only have a brain but no body, they are mutilated and incomplete.

Soon, this biggest head became familiar and hung up.

Flame Entropy was another high whip leg, kicking the head in the middle off and throwing it on top of the thermite powder.

It's charcoal grilled heads again.

When the second head was also cooked, the last remaining living mouth moved, and the metal synapses on the transparent device shimmered with a faint and incomprehensible light.

Although the brains can't make sound, they can communicate with each other through radio waves, and they can feel how painful the two roasted brains are before they die.

There were a few faint mechanical stops throughout the starship, the transport rails above which the triangulation was suspended came to a halt, and most of the flakes of black crystals were completely dimmed.

Yan Entropy flicked the metal transparent device with his finger: "Good boy, now, bring up the galaxy map to Lao Tzu." ”

The large black panels began to transform, and the runes vanished, replaced by an irregular image of physical strength filled with celestial bodies of different colors, large and small.

In terms of images, most galaxies have a similar appearance to the Milky Way, in addition to elliptical galaxies, there are lens galaxies, spiral galaxies, barred spiral galaxies, and many irregular galaxies, as well as many clusters of galaxies that are not very evenly clustered, ranging from two or three to hundreds.

Different galaxies are marked with a row of runes, including information such as whether they are absolute vacuums, the density of cosmic dust matter, the foggy spotted nebula, and the noble lord to which they belong.

Yan Entropy frowned and looked at it for a while, then pointed to one of the areas: "Seven hundred times magnification." ”

After the specific area was magnified, Yan Entropy nodded slightly: "This is the latest territory of the wither?"

The only remaining brain zoomed in on the entire area again, and a blue planet was revealed.

"Gray Knight Galaxy!" Yan Entropy showed an inexplicable smile: "What else?"

The galaxy map changed again, and many galaxies and the central planet of the galaxy appeared one after another.

Yan Entropy squinted his eyes and recorded all this important information.

Chu Ci and Qin Lele almost couldn't understand anything, and the two of them just watched the excitement at all, and they didn't rush.

They know that this information is important to Entropy, about faith, and about revenge.

After Yan Entropy understood all the information, he patted the transparency device again.

"Contact the withered blue pool!"
