Start sweeping the universe by rubbing the CPU with your hands.

Time passes slowly. Every progress in pterosaur breeding technology is tugging at people's heartstrings.

From the successful breeding of the first experimental farm, to the establishment of the second expanded farm, to the third and fourth...

By the tenth farm, the technology had completely matured.

In the end, the tenth official breeding farm was located on the water demon star in the asteroid belt.

The official number of Asteroid 165 is Asteroid 150. Its size is about kilometers, it is extremely barren, and there are no human settlements around it.

The main reason for choosing the location above it is to eliminate interference and prevent the pterosaur from escaping from the breeding farm.

This breeding farm covers a total area of ​​1 square kilometers. If one square kilometer accommodates 10 pterosaurs, a total of pterosaurs can be cultivated here.

Therefore, the artificially cultivated pterosaur hatchlings, one of which was about the size of an adult elephant, were carefully placed in the breeding area.

Different breeding areas are separated by high-strength alloys to avoid contact between different pterosaurs.

A breeding area covers an area of ​​about 6 square meters and is more than 200 meters high, which can fully accommodate an adult pterosaur.

For the next 100 years, these pterosaurs could only spend their time here.

These are still fragile - of course, in comparison. In fact, even a newly born pterosaur can easily fight against 10 adult tigers. The ability to adapt to harsh environments is far beyond that.

Even if they were thrown into a high-radiation vacuum environment of more than 200 degrees Celsius below zero, these pterosaur larvae would be completely fine.

Today, these pterosaur larvae are roaring ferociously in the breeding box.

But as up to 300 chickens were thrown in, the pterosaur larvae immediately calmed down and began to devour the delicious food.

Pterosaurs have extremely strong digestive abilities and can eat all living things, whether animals, plants, or even microorganisms and algae.

In extreme cases, even some simple organic compounds, such as methane and urea, can be eaten.

These nutrients will structure the body of the pterosaur together with the various minerals swallowed by the pterosaur, and provide an irreplaceable role in maintaining life and fertility.

After finishing eating, these pterosaur larvae immediately became lazy.

The living environment of pterosaurs is harsh. Now they have a stable food supply and have no motivation to hunt prey. Moreover, people have deliberately reduced their mineral intake, making it impossible for them to form hard armor, and they have no conditions to produce nuclear fusion and nuclear fission in their bodies. device, the combat effectiveness is reduced to a minimum.

This group of pterosaurs survived in the breeding farm.

As time went by, the weight of these pterosaurs gradually increased, and their food intake became larger and larger. On the eve of his release, his weight reached about 450 tons, and his food intake increased to the point where he had to eat 15 tons of food every day.

One hundred thousand pterosaurs means an average of 150 million tons of food per day. Assuming that a chicken weighs 1.5 kilograms, this is equivalent to one billion chickens.

Chicken is the cheapest animal protein that human civilization can produce.

Fortunately, the food of pterosaurs does not need to be entirely animal protein, and some plants can also be used.

As a result, a large number of pastures were born from human society, and large quantities of plants were also transported here, and filled into the bellies of pterosaurs together with chickens.

The huge food demand of pterosaurs has promoted the great development of the planting and breeding industry in human civilization, providing countless jobs and creating a large amount of social wealth.

The small water monster suddenly became the core of the asteroid belt, with a large number of heavy transport ships coming and going every day.

It transports food when it comes and transports pterosaur excrement when it leaves - this thing is also a good thing. Not only does it have industrial value, the residue also has extremely rich nutritional value and can be used as fertilizer and feed.

With sufficient food supply, these strange creatures that are so vicious that they can even destroy a small civilization are now round and round one by one, and they are lazy all day long, either eating or sleeping, and they look even more inexplicable. A bit of cuteness.

A hundred years later, these pterosaurs were all transported to the processing plant also built on the Water Demon Star, where they were all slaughtered and made into various pterosaur biological products including pterosaur capsules, which were supplied to human society. among.

The major capitals that participated in the investment and construction of this pterosaur breeding farm earned huge profits, and the human government also received a large amount of tax revenue.

Every worker in this industry chain received a generous salary and began to consume. As a result, the entertainment industry, catering industry, clothing industry, etc. were also stimulated and began to flourish. During this time, a large number of pterosaur breeding farms began to appear on other asteroids, ranging in size from a few hundred to a hundred thousand. Some zoos have even obtained breeding licenses and began to introduce pterosaurs for people to watch.

"The next thing to start is the pterosaur performance of drilling through the fire ring. We invite our cute little pterosaur - Feifei!"

In a venue with a height of several square kilometers, the audience watched the distant scenes through telescopes.

The steel gate opened, and a human held a rope in his hand. At the other end of the rope was a huge pterosaur that was ten meters tall and weighed up to a hundred tons.

The pterosaur was like a duck, obediently being led by humans to waddle out. It was full of comedy effect, and the people watching cheered and applauded. Many children even had little stars in their eyes: "Mom, look, what a cute big bird."

The little pterosaur named Fei Fei obediently lowered his head and let the keeper sit on his neck, then flapped his wings and flew up, nimbly shuttled between dozens of fire rings in the field, with his body either rotating, or The rapid turns and various special effects movements aroused cheers from the audience.

After the performance, the pterosaur was led by the keeper to the edge of the field. It began to imitate humans, put its wings on its chest and bowed, and began to bow. It kept acting cute, and people took the slaughtered chickens, ducks and fish in their hands. , mutton, beef, etc. were thrown in.

Seeing the food falling like raindrops, this chubby pterosaur was so happy that it rolled on the ground and couldn't wait to devour the food, which caused laughter in the audience.

At this moment, in people's minds, the image of pterosaurs has become the same as the chubby big birds in the zoo that only know how to be cute and begging for food, as well as the dazzling array of pterosaur biological products on the shelves, such as pterosaur capsules, pterosaurs Leather bags, leather shoes, etc. are linked together.

As for the terrible life that comes overwhelmingly and can even destroy a civilization and wipe out an entire planet's biosphere, it has completely disappeared from people's minds.

Human civilization is developing rapidly in peace and stability. At this stage, Han Yang takes an overview of the overall scientific progress and finally feels that the time has come for human civilization to launch an impact on the third-level civilization stage.

Just like before breaking through to the second-level civilization stage, people realized that technologies such as controllable nuclear fusion and ion propulsion are the keys to breaking through to the second-level civilization level. At this moment, they are about to launch an impact on the third-level civilization stage. Han Yang also noticed that What is the key to becoming a level three civilization?

Grand unified theory.

It is currently believed that there are four basic forces in the universe, gravity, electromagnetic force, strong interaction force, and weak interaction force.

These four forces are "fundamental". All other forces can be summarized under these four basic forces.

For example, the root of various chemical changes lies in the breakage and reorganization of chemical bonds, which occurs at the atomic and molecular levels. The fundamental factor that dominates changes at the atomic level is electromagnetic force.

Basically, all changes encountered in daily life, except gravity, are all dominated by electromagnetic force.

Even when humans eat and digest food, this process is dominated by electromagnetic forces. Because the essence of digestion is to react with food through stomach acid, which is a chemical process. The foundation of chemistry is electromagnetic force.

The weak force determines the decay of matter, and the strong force determines the violent nuclear change process, such as the explosion of atomic bombs and hydrogen bombs.

Of course, there is no need to mention gravity. It determines that people will not fall when standing on the earth, and determines that planets revolve around stars. Even on a cosmic scale, gravity shapes the face of the universe today.

The understanding, mastery and utilization of the four basic forces determine the scientific and technological level of a scientific and technological civilization.

But it is believed that these four basic forces can be unified under certain conditions. That is to say, these four basic forces are also different external manifestations of the same force.

Just like electricity and magnetism, people thought they were two different forces at first, but they were eventually unified into electromagnetic force.

Based on this idea, countless scientists have carried out research, and finally, they have unified the weak interaction force and the electromagnetic force into the electroweak interaction force.

At extremely high energy levels, about 100 GeV, the electromagnetic force and the weak interaction force have exactly the same properties, and there is no single electromagnetic force or weak interaction force.

In the early days of the universe, just after its birth from the Big Bang, when the temperature of the universe exceeded one quadrillion degrees Celsius, these two forces in the universe were unified. But later the temperature dropped, and because of the spontaneous symmetry breaking, the two forces separated into two types.

After unifying the electromagnetic force and the weak interaction force, although there has been progress in the research on the four fundamental forces, there has been no decisive breakthrough to unify the electroweak interaction with the strong interaction force.

The so-called grand unified theory is a theory that describes the unification of these three forces into one force.

If the most difficult to unify is gravity, and the four forces are unified together, it will be the legendary theory of everything. At least at this stage, Han Yang has no hope of realizing it.

But Han Yang has already seen hope in the grand unified theory, and has confirmed that this is the key to advancing human civilization to the third level of civilization.

As long as he can master the grand unified theory, then Han Yang can truly realize the unique technologies of the third-level civilization, such as non-propulsive propulsion, energy weapons, energy shields, etc. (End of chapter)
