This is the closest star system to the blue giant. Han Yang also carried out a huge construction in this star system. At this moment, this place has become the forward base for Han Yang to continue observing the supernova after all the detectors were destroyed.

Here, it is about 3.2 light years away from the blue giant.

Originally, the blue giant looked like just an ordinary star that was brighter and shining from here, and its brightness was about the same as that of Venus seen from the earth.

But at this moment, its brightness has surged to the brightness equivalent to more than 400 full moons at their brightest, and can even completely illuminate the earth of the planet where Han Yang is.

You know, if you look at the sun at such a distance, the sun's light will be so dim that it can only be barely seen.

And this is just the result of it passing the peak, the brightest moment, and the brightness has begun to weaken. At the same time, this is just the energy it radiates in the visible light band.

In the neutrino, gravitational wave, space dark energy, high-energy gamma ray, X-ray, ultraviolet and infrared bands, the energy it radiates and the kinetic energy applied to stellar matter far exceed the visible light band.

Because of this, the bases and various creations built by Han Yang in this star system also suffered a wave of baptism.

Except for those hiding on the back of the stars, those creations facing the direction of the supernova were directly destroyed even if they had made perfect protection preparations in advance.

If there are relatively low-level intelligent life in this star system, then there is no doubt that all intelligent life will be killed by the huge radiation of the supernova in an instant.

In fact, Han Yang believes that within a range of 500 light years from this supernova, all civilizations with a technological level below level 2 will be destroyed.

Even if they are not destroyed for a while, they will definitely be completely destroyed under the influence of various secondary disasters caused by the supernova explosion.

A sphere with a radius of 500 light years has a volume of about 520 million cubic light years. Such a vast space, just because of the explosion of a small star, was all killed like insects sprayed with insecticide.

Secretly sighing at the power of the supernova explosion, Han Yang continued to observe it.

Han Yang saw that a huge diffuse nebula had been formed at the site of the supernova explosion.

The stardust that made up the nebula used to be all the materials that made up the stars.

They were thrown out in the supernova explosion and are now rapidly spreading to the surrounding space at a speed of tens of thousands of kilometers per second.

In the core of the nebula, a black hole with a mass of 6.5 times that of the sun has been formed.

The event horizon of a black hole, or its size, is determined by its mass. Through some simple calculations, Han Yang immediately concluded that the radius of a black hole with a mass of 6.5 times that of the sun is only about 20 kilometers.

However, such a small star has now become the master of the entire vast nebula with a radius of about 1.1 trillion kilometers.

Because of the supernova explosion, all the outer materials that originally made up the star have gained enough speed to break free from the star's gravity. But with the formation of the black hole, the external matter continued to spread outward, and those materials closer to the black hole were pulled back without having time to escape.

At this moment, they were spinning around the black hole madly and falling into it madly, continuing to increase its mass.

In this process, violent jets were ejected from the two poles of the black hole, and the powerful radiation directly illuminated the entire nebula.

Even though it had been three years since the explosion, Han Yang still did not dare to send a fleet or detection force to the vicinity of the black hole. Because he knew that the environment there was still so bad that he could not imagine it.

No matter what he sent there, it was just to die.

Fortunately, with the destruction of up to 700 billion detectors, Han Yang had collected a lot of data, and there was no need to observe it closely.

Carefully storing these data and placing them under heavy protection, Han Yang left some observation forces in this star system and continued to conduct follow-up observations at a distance of three light years, and his main focus was transferred to the second observation point.

In about 1,000 years, this star will also explode. Moreover, under normal circumstances, the explosion of this star will be more violent than the previous explosion.

Because the mass of this star is larger.

In this star system, Han Yang repeated the previous observation plan. The difference is that Han Yang used more detectors to observe this star, reaching about one trillion.

Fortunately, Han Yang had more preparation time this time, so Han Yang had enough time to allocate enough resources and computing power to finally build these detectors.

After a long thousand years, accompanied by another neutrino explosion, Han Yang once again began to deploy large-scale detectors close to the star.

A few hours later, another violent explosion occurred, which was brighter than all the stars in the entire Milky Way. The trillions of detectors that Han Yang had worked so hard to build were once again clean and clean, without a single one left, and all were destroyed.

And Han Yang also obtained a lot of data again.

After that, Han Yang further determined the time of their explosions through continuous observation of the remaining three stars.

The most recent one will explode between 1500 and 1800 years from now.

The next one will explode between 3900 and 4500 years from now.

The next star will explode even further, 8000 years later.

Among them, Han Yang also made some unexpected discoveries.

Through further observation of the Canis Major dwarf galaxy, Han Yang also found two neutron stars orbiting each other and spinning madly.

The smaller of these two neutron stars has a mass of 1.9 times that of the sun, and the larger one has a mass of 2.3 times that of the sun.

They are spinning madly, their speed is getting faster and faster, and their distance is getting closer and closer. It is expected that within the next 10,000 years, they will collide with each other, and a black hole with a mass of 3.6 times that of the sun will be formed.

Most of the remaining mass of about 0.6 times that of the sun will be radiated into the universe in the form of gravitational waves. A small part of the mass will be thrown into the universe in the form of stardust.

These stardusts will contain all elements heavier than iron and nickel that cannot be formed by normal stellar fusion, such as gold and silver.

This is undoubtedly the formation process of a macroscopic black hole, and based on the different formation mode from stellar black holes, maybe we can observe something different from it.

But it took too long.

Although on an astronomical scale, 10,000 years, or even a million years, is just a fleeting moment, for Han Yang, this period of time is still too long.

What's more, Han Yang's observation focus is on the formation process of the macroscopic black hole itself. Although its predecessor star has a high observation value, it does not involve the fundamentals. Han Yang also gave up waiting for it.

At this moment, Han Yang has been in the Canis Major dwarf galaxy for thousands of years. It has been almost 30,000 years since he left the Milky Way.

After comprehensively analyzing the quantity and quality of the data he had obtained at this moment, as well as the integrity of the observation data on the birth process of macroscopic black holes, and considering the time factor, Han Yang finally made a decision.

After observing the supernova explosion and the process of macroscopic black hole formation again, Han Yang no longer waited, no longer stayed in the Canis Major dwarf galaxy, and went home directly.

Han Yang's computing power was transferred again, poured into the vicinity of the star that was about to explode recently, and started a larger construction again.

Because Han Yang had more time to prepare this time and it was the last observation, this time Han Yang doubled his observation power again, directly built a number of up to 2 trillion various detectors, and then deployed them layer by layer around the star again.

The long 1,700 years passed in a flash. At this moment, the star exploded again, ending its brilliant life with a magnificent and incomparable feast of light and heat.

Four years later, the energy of the supernova explosion reached four light years away, destroying the last detector laid by Han Yang.

Han Yang took back his computing power.

He knew that it was time to prepare for another intergalactic voyage and return to the Milky Way.

The preparations for the return flight had already been completed, and no additional work was needed at this moment.

However, Han Yang still did some other things.

He selected about 100 node star systems in various parts of the Canis Major dwarf galaxy and built more than 100 automated bases.

These bases have fully automatic industrial systems and self-maintenance systems, and have relatively comprehensive external observation capabilities.

Their brains are artificial intelligence programs developed by Han Yang based on level 5 civilization technology.

Under the guidance of this program, these automated bases will continue to conduct various observations of the surrounding star fields. Every hundred years or so, they will automatically launch an unmanned spacecraft, carrying the information observed during this period, and go to the Milky Way in a regular navigation mode.

After flying for more than 20,000 years, they will reach the Milky Way. If everything goes well, Han Yang will be able to recover these unmanned spacecraft and obtain the latest and most detailed information about the Canis Major dwarf galaxy.

Han Yang knew that this was probably not very useful. Moreover, automated programs are not as good as real wisdom.

Without their own supervision, it is hard to say how long they can run in the end.

However, after traveling thousands of miles to the Canis Major Dwarf Galaxy, it would be a waste if they did not leave something behind.

This did not take Han Yang much time. Han Yang had already completed it while he was sailing at superluminal speed and heading towards the edge of the Canis Major Dwarf Galaxy facing the Milky Way.

Traveling at a speed of 80 times the speed of light, Han Yang came to the edge of the Canis Major Dwarf Galaxy only 20 years later.

There is a lonely old red giant here.

It is the outermost star in the Canis Major Dwarf Galaxy and the closest to the Milky Way, like a protruding bridgehead.

It originally had four planets, but as it gradually expanded, three of them had been swallowed by it. At this moment, there is only a gas giant planet with a mass similar to Saturn orbiting it alone.

Fortunately, there are still several massive satellites around this gas giant planet, which allowed Han Yang to complete the last supply here.

At this moment, after a long voyage of 1,600 light years, Han Yang's fleet, which had consumed most of the supplies, once again recovered to its peak.

So the huge fleet set sail again, flying away from the red giant and also away from the Canis Major dwarf galaxy.

At the moment before entering the superluminal voyage, Han Yang turned back again and took a deep look at this tiny and weak galaxy where he had struggled for thousands of years.

What happened in the past few years, wars again and again, brilliant and heroic explosions again and again, seemed to be still vivid.

Now, I have got what I want.

So, it's time to leave.

"Goodbye, goodbye. I hope I will have another chance to come back here in the future. When that time comes, I wonder what you will become? Will there be a new level 5 strange life?"

Han Yang smiled freely: "It doesn't matter. If a new level 5 strange life appears, I will destroy it again."

The huge fleet entered the superluminal navigation state and traveled towards the Milky Way at a speed of 80 times the speed of light.

More than 30 years later, the fleet left the superluminal navigation and switched to the conventional propulsion mode.

The journey back to the Milky Way is much easier than the journey to the Canis Major dwarf galaxy.

Just like, it is very difficult to launch a missile from the surface to attack an airplane in the sky. It requires very accurate aiming and constant adjustment of the missile trajectory.

But it is very simple to attack the earth from an airplane. Even if you close your eyes and shoot randomly, the attack will definitely fall on the earth.

Although it is not so casual at the moment, it is not much different.

Han Yang no longer needs to adjust the orbit frequently. He only needs to ensure that the ships in the fleet can gather together and maintain a speed of 99% of the speed of light. Apart from that, he just needs to fly forward with his eyes closed.

Anyway, no matter how the orbit deviates, it will eventually fall into the Milky Way.

Because the Milky Way is too big.

Once he reaches the Milky Way and obtains material replenishment, Han Yang can go wherever he wants.

This is also the reason why Han Yang is sure that the automated observation bases left in the Canis Major dwarf galaxy can successfully return to the Milky Way by launching unmanned spacecraft under the control of intelligent programs.

Time slowly passed, and Han Yang saw that the Canis Major dwarf galaxy behind him was getting dimmer and dimmer. In front of him, the Milky Way was getting brighter and brighter.

In the vast void, Han Yang's fleet moved forward. (End of this chapter)
