At present, in front of Xiao Yu, there are two scientific and technological obstacles that need to be broken through urgently. One is elemental decay jishu and the other is faster-than-light sailing jishu.

These two jishu are complementary to each other. Elemental decay jishu, is the cornerstone of faster-than-light travel jishu. Xiao Yu has already done relevant experiments, taking the Hebei as an example, in theory, the 40 million tons of nuclear fusion fuel loaded on the Hebei are only enough to support the Hebei to carry out less than 100 light-years faster-than-light travel.

But this obstacle will be solved after the breakthrough of the elemental decay jishu. Because of volume limitations, the Hebei needs most of the space in the hull to load nuclear fusion fuel, that is, deuterium, but after replacing the same volume of deuterium with heavy elements, such as silicon, the most abundant heavy element on the earth, the Hebei will be able to carry 1.3 billion tons.

This means that if the voyage distance is calculated alone, the endurance of the Hebei will reach 10,000 light years. Of course, in reality it will be much smaller than this number, after all, there are many other places where the Hebei needs energy, such as calculations, such as defense, such as weapons and steering, and so on. According to comprehensive calculations, after the breakthrough of elemental decay, the endurance of the Hebei can reach at least one thousand light years.

At that time, Xiao Yu will fully enter the jishu level measured by light grade.

In an orbit of 2 billion kilometers from the central star, Xiao Yu and Lucca scientists are carrying out intense research work.

The Large Particle Collider has been placed in orbit around the central star. Because of the large size of this star, Xiao Yu had to disassemble hundreds of village-class spacecraft, rebuild some parts, and add them to reluctantly build a large particle collider. There is no way, inside this empty galaxy. Xiao Yu could not get any material supplements.

The central star is losing mass at a rate of nearly a billion tons per second, and this mass is ejected from the surface by the central star in the form of interstellar dust, scattered in the vast expanse of space. But Xiao Yu has no way to collect these qualities. Xiao Yu has made relevant calculations, if he builds a thousand giant collection nets powered by stellar energy and an area of one square kilometer, and constantly wanders in the universe to collect mass, he can collect about ten tons of material per hour.

This was obviously a loss-making business, and Xiao Yu gave up this idea very simply. Instead, dismantle the ship to obtain supplies. Anyway, it only needs to support two hundred years, and after two hundred years, it will either die or escape from this prison, this jihua, there is no need to execute.

In the more than a hundred years that had previously eluded the rest of the civilizations. The population of Lucca society has grown to more than 200,000. Lucca society is much the same as human society, but it lives much longer. Xiao Yu was reluctant to allow the Lucca scientists, who had mastered an extremely rich knowledge of all kinds, to die of premature aging. So Xiao Yu also did some research on biotechnology. At present, the average life expectancy of Lucca people has been raised to about 500 years.

After more than 100 years, the number of Lucca scientists has reached about 2,000. Luca III assumed the position of Supreme Governor of Science without objection, and Luca II still held the position of Highest Governor of Society.

In order to properly organize these studies, try to make the most of them. Xiao Yu dismantled the original provincial transport ship, used some of the materials for other purposes, and built a new municipal spaceship with the remaining materials.

This municipal-level spaceship, Xiao Yu named it "Eternal Country". Eternal Kingdom. It is the kingdom of the true gods in the legends of the Lucca civilization. In this spacecraft, Xiao Yu arranged extremely complete and state-of-the-art research equipment under current technology for the use of Lucca scientists.

The Eternal Realm is located not far from Paradise, and Luca's scientists can easily travel back and forth between the two ships in the small spacecraft assigned to them. In the Eternal Realm, they carry out scientific research, and in the Paradise, they can live and play comfortably.

At this moment, it is already twenty years after Xiao Yu has been imprisoned in this prison. In the midst of the Eternal Realm, Lucca scientists are working intensively on research.

The theoretical cornerstone of elemental decay jishu has been established, and what is needed now is a large number of shiyans to find the most efficient way to achieve it.

In a laboratory, several Lucca scientists in white coats are staring closely at a transparent glass box. In the midst of the glass case, there was a very common thing, a piece of iron weighing about a kilogram, floating there in the air.

Next to this transparent glass case, there are dense lines that extend out, and I don't know where they are connected, on which complex instruments.

Through these lines, some strange rays were emitted and acted on the iron block.

In the midst of the microscopic shijie, a violent reaction that is invisible to the naked eye is taking place.

It's a microstructure that's smaller than molecules, atoms. Within the range of the strong interaction force, the quarks that make up the hadron are suddenly dispersed, they are scattered in the empty space inside the atoms, and the phenomenon of quark exchange between different atoms is also generated. That is, quarks inside one atom sometimes run into the rest of the atoms.

They permeate the entire atomic space, and their distribution takes on the characteristics of "clouds", as if they were electron clouds.

This process, in the opinion of Lucca scientists, is that the volume of this piece of iron suddenly increases. At the same time, it begins to emit a faint infrared light.

"This should be a small-scale collision of quarks during dispersion, and the energy level jump caused the generation of photons." A Lucca scientist said.

After the scientist finished speaking, an assistant immediately recorded this passage and sent it to Xiao Yu through the communication system for Xiao Yu to analyze.

Scenarios like this are happening in dozens of labs at the same time, and data is submitted to Xiao Yu at every moment for Xiao Yu to analyze.

After the assistant had finished submitting, the scientist instructed: "Reverse the two instruments, increase the strong interaction force, and weaken the electromagnetic force." ”

“haode。” Another assistant agreed, pressing a few buttons on the instrument.

In the microscopic shijie, the quarks that permeated the internal space of the atom and showed the characteristics of an "electron cloud" suddenly seemed to go crazy, and each of them crashed into the nearest quark.

In the violent impact, quarks recombine into hadrons, such as protons and neutrons, and in the process, some quarks disappear out of thin air. They become photons, or neutrinos, that escape from the inside of this piece of iron.

In the eyes of Luca's scientists, it was the material in the glass case, which suddenly emitted an extremely dazzling light, which lasted for a full few minutes, and after a few minutes, the light gradually dimmed, and the iron reappeared. It's just that his size has shrunk by half.

Because the glass box has the function of blocking too strong light, the Lucca scientists who observed it outside were not affected by the strong light.

"Neutrinos were detected as well as bursts of photons, which carry very high energies. The results of the analysis showed that in this reaction, the kilogram of iron lost 48 percent of its mass, and its mass remained 520 grams. At the same time, the mass-energy formula shows that the energy carried by the photons and neutrinos emitted by it is exactly 480 grams when converted into mass, which conforms to the law of conservation of mass and energy. ”

"The combined excitation energy, neutrino loss energy calculation, the elemental decay comprehensive energy utilization rate is 40 percent. The remaining 8 percent of the energy is the necessary energy loss. ”

During the decay of an element, energy is emitted mainly in the form of photons, which are accompanied by the birth of photons, as well as some neutrinos. These neutrinos are like energy thieves, they steal the energy, take it for themselves, and then escape in an instant due to the fact that it is extremely difficult to react with the rest of the matter.

The energy stolen by neutrinos, the energy lost in the conversion process, and the energy required to initiate the conversion of electromagnetic forces and strong interaction forces, were comprehensively calculated, and it was concluded that in the decay process of the elements, up to 40% of the mass is converted into energy, which can be used by Xiao Yu.

"This is the highest energy efficiency experiment among tens of thousands of shiyans in recent decades, and in this way, safety and other aspects can be effectively guaranteed. Submit the whole process of this shiyan, as well as our conclusions, to the master. ”

The scientist who presided over this shiyan could not hide the joy on his face, and his voice was a little hurried and commanded his assistant.

"Congratulations, Lord Wells, with this achievement, I think the master will definitely assign you the honorable title of 'Lucca IV'." An assistant next to him said with envy on his face.

The name that Xiao Yu casually mentioned at the beginning has now become the supreme honorary title in Lucca society. You must know that in the entire Lucca society, with a population of more than 200,000 people, there are only two people who have obtained such titles: Lucca No. 2 and Lucca No. 3. These two people, one is the supreme scientific consul and the other is the supreme social consul. It is conceivable that after the second and third, the title of Lucca IV represents what a high honor.

However, Xiao Yu is not ready to give away the title of Luca No. 4 easily. The title of Lucca IV is like a crown of honor, inspiring thousands of Lucca scientists to fight for it.

However, after receiving the latest Shiyan report on elemental decay in the Eternal Kingdom, Xiao Yu had a hunch that he had to give away this hat. (To be continued......)
