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

At this moment, as a huge amount of hydrogen and helium, which make up this gaseous planet, rotate and fall into the white dwarf star, the brightness of the entire white dwarf star has increased thousands of times compared to before.

The endless gas even formed a cloud around it. This cloud revolved around it crazily, violently rubbing against each other, and the energy rose rapidly, even forming obvious jets at the poles of the white dwarf.

Overall, the clouds surrounding the white dwarf star are like swaddling clothes.

Human swaddling clothes are used to raise newborn babies. At this moment, the infancy of the white dwarf star is also gestating some extremely terrifying changes.

Although the radiation from this white dwarf star is violent at this moment, it is enough to sweep across the entire star system. If it is placed in the solar system, even human civilization that has entered space and can even conduct interstellar navigation will not be able to withstand it.

But compared to a blue supergiant star that is extremely violent and often throws out several or more than a dozen Earth-mass stars, it is completely insignificant, and it is even less likely to cause significant damage to clusters of strange life forms.

At this moment, it is nothing more than making the environment in the galaxy even worse.

However, as time goes by, as the gaseous planet approaches its disappearance, and as most of the 900 trillion tons of hydrogen and helium that make up it fall into the white dwarf, a critical point is finally reached.

The gravity on the surface of a white dwarf is extremely strong, even hundreds of thousands of times that of the Earth. Under the compression of such a strong gravity, all the hydrogen and helium that reach the surface of the white dwarf star will be extremely compressed.

Compression means an increase in temperature, and the temperature of these hydrogen and helium quickly increased to tens or even hundreds of millions of degrees Celsius.

This environment is similar to the core environment of a star.

In the core of a star, due to high enough temperature and pressure, hydrogen and helium will undergo nuclear fusion, converting mass into energy, allowing the entire star to glow and heat.

So, what will happen if the surface of a white dwarf has an environment similar to that in the core of a star?

Obviously, the hydrogen and helium here will also undergo nuclear fusion.

Nuclear fusion will release energy, which will cause the temperature and pressure on the surface of the white dwarf to further increase.

If it is in the core of a normal star, the increase in temperature and pressure caused by energy will cause the star to expand due to the excessive internal pressure.

As the star expands, the internal pressure will naturally decrease, the temperature will also decrease, and the nuclear fusion rate will naturally slow down.

In this way, stars can form a dynamic balance between internal pressure-nuclear fusion-volume, and maintain a roughly stable nuclear fusion rate, that is, neither too fast nor too slow.

But on the surface of a white dwarf, this dynamic balance adjustment mechanism will fail.

Hydrogen and helium undergo nuclear fusion, further increasing the temperature and pressure. The increase in temperature and pressure will lead to greater pressure and faster fusion rate.

But the gravity of a white dwarf star is stable and will not decrease as the pressure increases. Therefore, the more nuclear fusion occurs, the higher the pressure and temperature. The higher the pressure and temperature, the faster the rate of nuclear fusion.

What are the consequences of this?
Quite simply, this will inevitably lead to a catastrophic and uncontrolled chain fusion of all the fuel available for fusion in a short period of time, and all the fuel will be fused away in a very short period of time.

This mechanism is somewhat similar to a hydrogen bomb. The difference is that the TNT equivalent of the largest hydrogen bomb created by mankind is only about 1.3 million tons. When converted into mass, coupled with the reaction ratio of nuclear fusion, such a bomb is so powerful that it can even change the earth's crust. For a hydrogen bomb, the total mass of hydrogen elements participating in the reaction is only about 10 tons, of which less than kilograms of hydrogen elements are converted into energy.

At this moment, the runaway and catastrophic interlock reaction nuclear fusion is taking place on the surface of this white dwarf star. How many hydrogen and helium elements are involved in the reaction?

Almost as high as 900 trillion tons!

Such a large amount of mass, due to the super strong gravity of this white dwarf star, reacted in almost an instant, and the energy released was so powerful that it was almost unimaginable.

In comparison, the energy released in the early stage due to the impact of gaseous planetary gas on the white dwarf was just a drizzle and not worth mentioning at all.

The energy that burst out at this moment was what Han Yang really expected.

In this moment, the brightness of the white dwarf star even increased to tens of thousands of times. At its peak, it even grew to a level comparable to that of a blue giant star.

Really violent energy began to sweep across the entire star system.

At this moment, it was not the strange life forms that bore the brunt, but Han Yang's battleship.

A fleet led by dwarf planet-class battleships with more than 5000 small and medium-sized battleships.

Facing this huge energy impact like a roaring mountain and a tsunami, the multi-layered dark energy shield that Han Yang was proud of was like a fragile egg shell, not even able to hold on for a microsecond before it shattered.

The super alloy that made up the battleship was vaporized in an instant and completely turned into cosmic dust.

After that, it was the strange life that caused Han Yang a lot of trouble in the early stage, similar to the pterosaur he encountered before.

This strange life has a huge body, extremely maneuverable, and extremely strong defense. Often Han Yang's several warships bombarded them head-on, but they were unable to break through their defenses.

There are currently more than 10,000 of these monsters here.

After Han Yang's fleet was destroyed, a violent energy impact came to them.

So the next moment, the powerful monster that gave Han Yang a headache was also like a chicken, its defense was broken instantly, and it was vaporized and disappeared without even having time to let out a mournful scream.

After that, there is a large group of combined strange life forms tens of millions of kilometers away from the white dwarf star.

This kind of strange life can combine with each other to form a larger combination and obtain more powerful combat effectiveness. In previous wars, they also caused huge trouble to Han Yang.

But at this moment, this combination of hundreds of thousands of head bodies was also vaporized and disappeared in an instant.

After that, there are Han Yang’s hundreds of billions of interstellar mines, hundreds of thousands of spy satellites, hundreds of thousands of small unmanned warships, a large number of interstellar forts, as well as a huge number of Zerg worms, hundreds of billions of strange life forms... …

No matter what it is, whether it is a strange life, or a technological creation, whether it is a small interstellar mine, or a huge satellite-class battleship, facing this huge energy that can almost destroy the world, there is no way to resist it. They were all vaporized in an instant and disappeared.

The violent energy from the white dwarf really swept across the entire galaxy.

It is like a powerful disinfectant, and all technological creations and strange life forms living in this galaxy are like fragile bacteria.

Wherever the disinfectant reaches, all the bacteria there will be destroyed.

The galaxy that was originally filled with energy became completely silent under the energy impact of this white dwarf star.

It was so quiet in space that not even a broken arm could be seen.

Han Yang's powerful fleet was nearly wiped out. The cluster of strange life forms is also on the verge of total extinction.

The reason why there was no real total annihilation is because there are still some beings in this star system that can withstand such a violent energy impact. That is the macroscopic star.

Dwarf planets or large planets.

Although the atmosphere of planets with atmospheres is directly stripped off, and the surfaces of planets without atmospheres are directly scorched, and gaseous planets set off violent storms, they can still be regarded as shields because of their large enough mass and thickness. .

During the explosion, those who happen to be hiding on the back of the planet will be able to escape.

But the same cannot be said for those that exist in space. No matter how powerful they are, they will all be destroyed.

Han Yang controlled the few surviving detectors to leave the back of the planet and began to observe the current situation in the galaxy.

At this moment, Han Yang, who saw these scenes, couldn't help but be shocked.

Although these changes are all caused by my own hands. But theoretical calculations are different from actual seeing.

"This is the new star..."

Han Yang sighed silently in his heart.

That's right, the violent energy explosion happening on the white dwarf star at this moment is actually not uncommon in the universe. Including human scientists, all intelligent civilizations that have reached a certain level have studied this and have given it a special term, nova.

A nova generally refers to a type of star whose luminosity suddenly increases dramatically. Because the luminosity suddenly increased, they could be seen with the naked eye, which were originally invisible to the naked eye. They looked like new stars appearing in the sky, hence the name nova.

With the development of science and technology, people have learned more about novae, and have gradually classified more types, such as supernovae, hypernovae and so on.

The word "nova" also specifically refers to the physical process in which a white dwarf star explodes due to accretion of matter.

However, under natural circumstances, the process of nova is usually caused by the white dwarf accreting material from the companion star and accumulating enough fusion fuel before it explodes.

But here, the white dwarf is too far away from the blue giant, and it is obviously impossible to accretion the material of the companion star, so Han Yang needs to manually feed a gaseous planet in the past to trigger it.

Anyway, the material composition of gaseous planets and stars is similar, both hydrogen and helium. Accreting stellar matter can explode, and accreting gaseous planets can also explode, as long as the total amount of matter is sufficient.

It should be noted that although they are both caused by white dwarfs, Type Ia supernovae are two completely different types from the nova explosion occurring now.

The so-called supernova, if you understand it literally, you can know that a supernova is a super violent nova explosion process.

Its energy release is even greater than the current nova explosion.

Type Ia supernova is a type of supernova. Its original star is also a white dwarf star, and the process is also due to the accretion of matter from the outside world.

But it accreted too much material, which not only provided the surface layer of the white dwarf with enough conditions to trigger chain nuclear fusion, but also caused a huge increase in core temperature due to the increase in gravity, even to the point where the carbon element in the core of the white dwarf The point where fusion occurs with both elements and oxygen.

As a result, huge energy was released both inside and outside, and the entire white dwarf star was completely blown to pieces with a bang. All the matter in the entire star will turn into high-energy radiation and impact the universe.

A white dwarf star can only undergo a Type Ia supernova explosion once in its lifetime, because once it occurs, it will be completely blown to pieces.

But the nova explosion at this moment can happen repeatedly.

As long as there is enough material, it can explode repeatedly. Of course, the energy intensity of a single explosion is naturally far inferior to that of a supernova explosion.

But for this moment, the explosion of new stars alone is enough to wipe out most of the strange life forms that exist in this star system.

Although most of his fleet was also wiped out, Han Yang didn't care.

Because at this moment, a huge fleet mobilized from nearby star systems is already in place.

After the nova explosion, although it has improved a lot compared to its peak, the interstellar environment is still extremely harsh. Up to a million battleships, numerous automated combat facilities, and countless detection equipment are once again scattered across the interstellar space. middle.

Han Yang began to search for the existence of each strange life entity and killed them all in an orderly manner.

During this process, a large number of strange life forms began to choose to flee. But how could they be Han Yang's opponents without a collective? They were often killed by Han Yang within a short time of escaping.

What was somewhat beyond Han Yang's expectation was that the fifth-level Zerg mother worm, which had assumed almost all logistical transportation tasks in the previous war, did not die completely under the violent energy impact of the nova explosion.

Although most of the body was damaged, with some areas even missing tens of thousands of square kilometers, a few parts of it were still spraying out worms in twos and threes.

Han Yang sneered in his heart, and then dropped thousands of large-yield quark fusion bombs without mercy, killing it directly.

After annihilating some of the strange life forms that were finally found, the entire galaxy, except for the blue giant star that was still showing off its enthusiasm, finally became truly quiet.

At this moment, Han Yang suddenly felt a surge of pride in his heart.

He checked the long-distance communication network of the Canis Major Dwarf Galaxy and found that it was still silent.

He looked deep into the starry sky, where it was still as peaceful and dead as ever.

In the past, Han Yang always felt that there seemed to be countless eyes in the vast starry sky, looking at him greedily and ferociously, ready to move in the dark, and might jump out at any time.

But now, with more than a dozen level five strange life clusters being wiped out by him, that feeling of being spied on has completely disappeared.

The tranquility at this moment is the real tranquility.

"Who else?!"

Han Yang took the initiative to send a message to the over-distance communication network of the Canis Major Dwarf Galaxy, and then repeated these three words tens of thousands of times.

The long-distance communication network is still quiet, without any fluctuations.

"No more? Very good."

Han Yang stopped the information broadcast and focused his attention on the blue supergiant star in front of him.

Due to the impact of the nova explosion, its expected explosion time has been advanced again. It is probably less than 500 years before it actually explodes.

It's time to go all out and start observing. (End of chapter)
