After teleporting Xiao Yu to this unknown star field, the ghost clan transformed by human souls disappeared, and I don't know where it went.

Xiao Yu sighed and began to plan for his future.

At present, the first thing to determine is where this is, whether it is still in the galaxy, and second, to determine how much time has passed in the outside world during this day's journey.

This is a large nebula with a length and width of more than ten light years, and this nebula belongs to the luminous nebula.

There are three types of nebulae, which are luminous nebulae, reflective nebulae, and dark nebulae. Luminous nebulae, as the name suggests, emit visible light on their own. A reflected nebula is one that can reflect light from other stars, while a dark nebula is one in which there are no stars nearby and no stars inside it, so it is not visible in the visible light band, but it can be found by looking for black areas in a bright background.

Before Xiao Yu met the Moluton civilization, the nebula he had passed through belonged to the Dark Nebula. The nebula where Xiao Yu is now is a luminous nebula.

This nebula is an extremely efficient and huge star factory. Countless interstellar dust gathers into stars, and the ultraviolet rays emitted by young stars ionize the interstellar dust, so in the visible light band, they appear reddish slightly.

So the starry sky here is not dark, but red. Here, you can see a magical phenomenon, bright young stars inlaid in the reddish sky, like bright gems, very beautiful.

But after beauty, there is danger. Because of the large concentration of young stars, the radiation levels here are dozens of times higher than in the rest of the universe. Moreover, the larger the star, the shorter its age, and the shortest-lived giant star has a lifespan of less than 10 million years.

When a star dies, it has a different fate depending on its mass, and a star similar to the mass of the Sun will turn into a white dwarf after death. After a supernova explodes, the remaining core mass exceeds the Chandrasekhar limit, which is about 1.44 times the mass of the Sun, and its core will form a neutron star.

If the core mass of a supernova still exceeds the Oppenheimer limit, which is about 3.22 times the mass of the Sun, after the supernova explodes, it will collapse into a black hole.

So it is certain that behind this unusually beautiful reddish canopy, there must be more than one neutron star, a white dwarf and the like, and even, the most dangerous star in the universe, the black hole.

At this stage, these dangerous stars are fatal to Xiao Yu. Xiao Yu decided that here, his actions must be careful and careful.

"It's so beautiful here...... But where is this? Xiao Yu sighed.

Perhaps because these stars are covered by a dense band of dust, there are no stars here that have been included in the Heroes Firmament. In order to find the initial coordinate point, you must search outward.

Xiao Yu's gaze extended beyond the nebula. Because of the obscuration of the nebula, the stars beyond the nebula appear unusually faint and even imperceptible. To this end, Xiao Yu used a variety of observation methods, such as visible light band, X-ray band, infrared, ultraviolet band and other observation methods.

"It's an aging red giant, so small in mass that it's not even qualified for a supernova explosion, and it's ...... distance It's about 3,000 light years, and it's not included in the Heroes of the Sky Record. ”

Xiao Yu shook his head, and after including it in the Heroes Sky Record, he gave up this goal.

"This is a red dwarf, only ninety-three times the mass of Jupiter, and as a star, it is really too small, and it is not included in the Heroes Sky Record." After also including it, Xiao Yu gave up this goal.

"Huh? It's a ...... Pulsar? How is it that its rotation speed, and the intensity of its pulses, as well as the nebula, are so familiar? ”

Pulsars are a type of neutron star, and if a neutron star can emit high-frequency pulses, it is called a pulsar.

When searching for the thirty-fifth star, Xiao Yu found a familiar pulsar, and immediately, Xiao Yu launched a search in the Heroes Sky Record, and after a tenth of a second, Xiao Yu found a star that matched all the data of this pulsar.

Xiao Yu's spirit was shocked, and he immediately launched a more detailed observation.

In the next five hours, Xiao Yu observed the pulsar from radio waves to gamma rays, collected a lot of data, and finally, Xiao Yu determined that this pulsar was the one he included in the Heroes Sky Directory.

"It's ...... That pulsar in the Crab Nebula. Xiao Yu came to a conclusion.

This result made Xiao Yu breathe a sigh of relief. Because this proves that he is still in the Milky Way, and he is not lost in the vast starry sky of the universe.

It was about 1,200 light-years away from itself. The distance between the Crab Nebula and the Sun is about 6,500 light-years.

Finding the Crab Nebula, Xiao Yu began to try to locate the position of the sun. But the sun is just an ordinary yellow dwarf, and this is a place hidden by many nebulae, so it really took Xiao Yu a lot of effort to search for the sun.

Fortunately, in these years, Xiao Yu's science and technology have developed greatly, and correspondingly, astronomical observation methods have also been constantly innovated, applying the latest technology, and finally, half a month later, through the ultra-large radio telescope, Xiao Yu found the trace of the sun.

Here, you can't see the sun in the visible band, but you can find it in the infrared band.

After finding the sun, Xiao Yu began to extend, with the sun as the initial coordinate point, and one after another familiar stars were found by Xiao Yu. In the end, Xiao Yu determined his position.

"Original...... This is the Aquila Nebula. The Aquila Nebula is 6,000 light-years away from the Sun and the four galaxies of the Celestial Garden, and in the course of this day, I have crossed a long distance of more than 6,000 light-years from the Celestial Four Galaxy......

In Xiao Yu's heart, he couldn't tell what it was like.

Moreover, in the process of locating his own position, by measuring the movement of stars such as the Sun and the Crab Nebula relative to some reference neutron stars, Xiao Yu also estimated the time he spent on the journey.

The conclusion is that during the journey, Xiao Yu only felt that one day had passed, and more than six thousand and one hundred years had passed in the outside world. The time ratio has reached a terrifying 1:2.2 million.

Through the time ratio, Xiao Yu also deduced that during the voyage that day, his average speed was about 99.9999 percent of the speed of light.

"Well, since my people sent me here, then I can develop here with peace of mind." Xiao Yu comforted himself.

After determining his location and time, Xiao Yu began to busy packing up.

The Wraiths had brought the remnants of Lucca's fleet here. That's about 20,000 Lucca ships, including even eight city-level ships. Of course, due to the attack of the Ghost Clan, the energy shield engines of these ships were all damaged due to overload. However, judging from the attack method of the Ghost Clan, except for the energy shield engine, these ships should not have any major damage.

Thinking of this, Xiao Yu's heart began to get excited. Xiao Yu did not forget that when Luka's fleet came to capture him, the two weapons of destruction from the fourth-level civilization were carried.

The force field generator was loaded on the provincial spaceship, and the provincial spacecraft had already exploded, so the force field generator didn't need to think about it, but Xiao Yu remembered very well that they also had another level 4 civilization weapon. That is, with just one, you can empty a gravity bomb of matter within a radius of hundreds of kilometers!

They carry tens of thousands of gravity bombs, but in the battlefield, the number of gravity bombs that explode, no more than a thousand. In other words, the gravity bombs that have not yet exploded are all owned by Xiao Yu.

This huge harvest made Xiao Yu very excited. Moreover, in addition, there are more than 20,000 Lukka spaceships, from which Xiao Yu will be able to harvest more technology, which is also very important to Xiao Yu.

Xiao Yu sent countless robots and began to land on these Luka spaceships.

Xiao Yu is very clear about the structure of Luca's spaceship, after all, Xiao Yu has experience in dissecting Luka's spaceship, so Xiao Yu's robot can easily find the power system and control system of the spaceship.

Inside the spaceship, Xiao Yu saw countless Lukka people who had long since died. However, Xiao Yu didn't put too much effort into these things, just collected them and cremated them hastily.

The fuel for these spaceships was still sufficient, so there was no need for Xiao Yu to draw fuel from his own spaceships. Xiao Yu manipulated the robots, made certain modifications to the operating systems of these spaceships, and installed ultra-long-range communication instruments, and these spaceships belonged to Xiao Yu from then on.

The number of spaceships in Xiao Yu's fleet increased to 130,000 in an instant. Among them, there are 16 city-level spaceships, and the number of county-level spacecraft has reached 3,000.

The damage to the Lukka spacecraft is not serious, as long as the energy shield engine is repaired and the energy shield is regained, the performance of these Lukka spaceships will be even better than Xiao Yu's own spaceship.

After modifying the spacecraft's control system and power system, and initially repairing the energy shield system to make it have basic meteorite impact resistance, Xiao Yu controlled the huge fleet and started a new journey.

This time, the target of the voyage is the star closest to him.

This star is only 0.3 light-years away from Xiao Yu, and as long as it takes about 30 years to sail, Xiao Yu can reach his destination.

Thirty years is not a long time for Xiao Yu.

In the pale red cosmic space, Xiao Yu's fleet was driving rapidly.
