Xiao Yu remembers very well that the home of all mankind, the earth, exploded.

The explosion of the earth led to the destruction of all mankind, and only Xiao Yu, the lucky one, escaped in advance.

Xiao Yu had always had a suspicion before, that is, whether the explosion of the earth was deliberately manipulated by some mysterious and unknowable being. But this suspicion has not been proved by evidence, so Xiao Yu can only bury this doubt in his heart and wait for his technology to be developed enough before exploring.

Xiao Yu's known information is that the earth's iron-nickel core, under the influence of some unknowable force, underwent proton-neutron fission, and the heavy elements quickly decayed into light elements, and the rest of the mass turned into energy, which led to the explosion of the earth.

The release of this energy is extremely intense, far exceeding that of nuclear fusion. The mass-to-energy conversion rate of nuclear fusion is about 5 percent, that is, in nuclear fusion, about 5 percent of the mass is converted into energy. And this unknown change, its energy conversion rate is almost as high as fifty percent.

Such a huge energy instantly blew the earth apart, and also led to the destruction of the earth.

The release of energy is divided into several levels, which are closely related to the microscopic shijie. Among them, chemical energy, such as conventional explosives, such as hydrogen and oxygen combustion, belongs to chemical energy, and the microstructure involved is at the molecular level, that is, the atoms are recombined into molecules to release energy. Nuclear fission and nuclear fusion, on the other hand, are at the atomic level, that is, protons and neutrons recombine and change into new atoms, releasing a large amount of energy in the process.

The source energy of the earth's explosion observed by Xiao Yu is the energy released in the process of recombining the quarks, antiquarks, gluons and other elementary particles that make up protons and neutrons.

It's a completely new source of energy that humans have never had access to.

Xiao Yu didn't know before that this unknown and mysterious force was man-made or naturally formed in the universe. After escaping from Earth, Xiao Yu has conducted a lot of research on this aspect, but due to the limitations of basic physical theories, Xiao Yu has not been able to produce results.

Now, Xiao Yu's suspicion of the source of this power has deepened again.

Because...... These aliens, their planets, are also the end of the explosion. How similar is this to Earth?

Xiao Yu was itchy and eager to know the next record, but the current data decipherment work only cracked this sentence, and the rest of the work could only be known after a protracted cracking work.

With no choice, Xiao Yu could only speed up the speed of decipherment while waiting anxiously.

The construction of the base, the collection of raw materials, and the construction of spaceships have been going on, and during this time, Xiao Yu has built forty new village-level spaceships.

These newly built ships have greater mobility, defense, and firepower. Because some preliminary scientific and technological analysis work has been completed, Xiao Yu has mastered the science and technology of the lizardman civilization in this regard.

Xiao Yu was surprised to find that the principles of these lizardmen's technology on material enhancement were not much different from his own. When Xiao Yu strengthened the material, it was achieved through the radiation influence of the wood spirit and the addition of the corpse of the black worm, and the specific principle was to change the molecular arrangement structure of the material through the two creatures of the wood spirit and the black worm to make it more compact, so the various properties of the material would be further improved.

Xiao Yu had already done research on this before, but it had been imperfect, and he had not been able to create such a tough material by artificial means. Now, with the scientific and technological supplement of the lizardman civilization, Xiao Yu immediately made a breakthrough in this aspect of science and technology.

In terms of mobility, the breakthrough is achieved through more efficient nuclear fusion engines. In terms of firepower, it is a more reasonable electromagnetic coil acceleration technology.

Science and technology are divided into two parts: science and jishu. Compared with Xiao Yu, the lizardman civilization is more advanced than Jishu, and its scientific theory is the same. Therefore, Xiao Yu can make a breakthrough immediately after obtaining jishu in this regard. If at this time, if Xiao Yu is given a machine with anti-gravity technology or over-distance communication technology, Xiao Yu will have to take a lot of trouble to master its construction principle, this is the difference between science and jishu.

Specifically, the difference between the machine guns used by the human armies during World War I and the machine guns used by humans in the 21st century is jishu, not science.

The appearance of the forty newly built village-level ships is no longer a spherical structure. Because the material is strong enough to withstand such a powerful overload, it is no longer necessary to compensate for it in terms of appearance.

Xiao Yu built these forty village-level spaceships into extremely stylish warships, just like alien spaceships in human science fiction movies.

These ships have a streamlined appearance, a sci-fi fuselage, and beautiful wings. Anyway, there is no air resistance in space, and as long as the shape of the spaceship is reasonable, it can be built however it wants.

In terms of energy weapons, Xiao Yu also made a breakthrough by analyzing an unfinished energy cannon.

The basic principle of the so-called energy weapon is to synthesize a compound of the element einthony, and after heating it to a high temperature of tens of millions of degrees in a strong magnetic field, the einium will become extremely unstable and have extremely high energy.

Energy weapons require only a few milligrams of einium to inflict great lethality, and due to their extremely small mass, they can be accelerated to extremely high speeds, even up to tens of thousands of kilometers per second. At the moment when it is launched and collides with an enemy target, these milligrams of eintonium will explode instantly, and the lethality per unit area is even no less than that of a hydrogen bomb. However, due to the extremely short half-life of einium in this state, which will decay into other elements in a short time, its strike radius cannot exceed 30,000 kilometers, even with a relativistic effect.

And because it can only exist in the natural environment for a very short time, it must be launched as soon as it is completed. This requires extremely powerful fusion reactors, which means that this weapon can only be equipped on large spacecraft.

Xiao Yu finally understood that Weishenme was only equipped with this kind of energy weapon on that alien flagship, and he also understood that Weishenme would only fire an energy cannonball after a long time.

But despite all its limitations, it is still an ideal weapon for space warfare.

Xiao Yu didn't forget that when he clashed with the lizardmen civilization, the other party's flagship relied on this energy weapon to kill and injure at least eighty of his village-level and township-level spaceships, accounting for almost one-seventh of his total number of lost spaceships.

Eintoinium can be produced by special means in a nuclear fusion reactor, and the heating process can also be done in a fusion reactor. What Xiao Yu has to do is to create a strong magnetic field again, and through many shiyans, this weapon will become more ideal.

After the breakthrough of the energy weapon, Xiao Yu immediately started the manufacture of the county-level spaceship in the space dock. This time, it was a county-level spacecraft of 800,000 tons, almost three times the size of the original Sun. Moreover, with a large amount of raw materials returned from the lizardmen's urban demolition activities, Xiao Yu planned to build two ships at a time.

Xiao Yu inherited the names of the Yuanhang and Tianyuan, which were wiped out by the lizardman civilization, and still named the two spaceships Yuanhang and Tianyuan respectively.

The construction of a new photonic computer was also put on the agenda by Xiao Yu. After observing the technology of the lizardmen to make photonic computers, combined with his own perception, Xiao Yu had a new idea, and after Shiyan was feasible, he immediately applied it to the construction. When the new photonic computer is built, it is expected that it will be ten times faster than the current photonic computer on the Sun.

At that time, this new photonic computer will be equipped with one on each of the New Yuanhang and the New Tianyuan. At that time, Xiao Yu will have two shelters, and he no longer has to worry about losing his computing power in an instant after the flagship is destroyed.

This is the harvest season, after the difficult destruction of the lizardman civilization, Xiao Yu has made great breakthroughs in material technology, weapon technology, power system, computer technology and other aspects.

"It's not in vain that I've lost so many ships." Xiao Yu thought happily.

After recycling all the recyclable materials in the city and smelting all his spaceships to rebuild, Xiao Yu is expected to be able to build 1,000 village-level spaceships, 120 township-level spaceships, and two 800,000-ton and one 400,000-ton county-level spaceships. Xiao Yu does not plan to prospect for mining on this planet, because on this planet, all kinds of minerals are too barren, and this city is estimated to be the accumulation of lizardman civilization for thousands of years, and now, it is all cheap Xiao Yu. Nuclear fusion fuel, Xiao Yu also found a lot in the dozen or so giant planetary engines with a height of 10,000 meters.

The entire construction process is estimated to take more than ten years. Xiao Yu is sitting in the Sun in space, presiding over all this.

Time passed gradually, and in the blink of an eye, three years had passed. Xiao Yu finally cracked the second paragraph of this core information.

"Our interstellar technology is not mature, and during the three-year-long interstellar voyage, our spacecraft suffered serious malfunctions. This has led to the loss of another half of our population. But with the blessing of God, the seeds of our civilization have finally reached the new planet. ”

"After escaping to this planet, we witnessed the destruction of our home planet. Our scientists have engaged in heated discussions analyzing the causes of the explosion on the home planet. But they argued for several years, but none of them came up with a single result. It was at this time that one of the greatest scientists came up with an astonishing theory. ”
