Looking at Planet No. 1 gradually moving away, and looking at Sky Eagle III that was gradually fading, Xiao Yu felt inexplicably sad in his heart.

This is another long journey, Sky Aquila 4 is 2.5 light years away from Sky Aquila 3, and at Xiao Yu's current speed, it will take about ten years to reach it.

Xiao Yu's current maximum sailing speed can reach 70,000 kilometers per second. In fact, in astronautics, before being limited by the theory of relativity, as long as the fuel is sufficient, the spacecraft can accelerate without limitation. Xiao Yu's sailing speed has always been low before, because of the limitation of fuel he can carry.

But this problem was largely solved after the construction of the Hebei spacecraft. The total mass of the Hebei is now nearly 100 million tons, half of which is fusion fuel. In addition, Xiao Yu also built dozens of material transport ships equivalent to the size of provincial spaceships, which were full of nuclear fusion fuel in addition to the fingers of alien beasts and Zerg materials, as well as some construction materials in reserve. Due to the simplicity of these ships, it was not too laborious to build them.

Building a large spaceship isn't as simple as stacking steel plates. It will involve material technology, engine technology, large shield technology, and many other sub-technologies such as weapon technology, power technology, and so on. Xiao Yu has estimated that based on the development speed of human science and technology in the earth era, it will take more than 200 years to develop from a municipal-level spaceship to a provincial-level spaceship.

In other words, if a provincial-level spaceship can be created, then this civilization is already in the middle and upper reaches of the third-level civilization, and it already has enough knowledge reserves, and it is no longer far away from the fourth-level civilization.

That's why Xiao Yu is so eager to go to the Aquila Four Galaxy. Because there. There may be a mystery hidden about the theory of great unification.

Previously, the Lukka civilization, which was still at the beginning of the third-level civilization, also owned a provincial-level spaceship, which was later destroyed by the attack of the Ghost Clan, and that spaceship was actually exchanged for the Guardian Alliance's contribution.

In the vast space, Xiao Yu's fleet was slowly accelerating.

Because of the existence of large transport ships, Xiao Yu's fleet acceleration is only about thirty meters per second. Xiao Yu will continue to accelerate at this acceleration for a month, and then rely on inertia to sail for about ten years. Then slow down for another month, and you can reach the Aquila four system.

Xiao Yu's fleet is composed of more than 100,000 large spaceships and dozens of material transport ships, and all the ultra-miniature spaceships are not part of the materials that Xiao Yu has recycled. The rest were abandoned by Xiao Yu. Carry these things with you on a long journey. It's not necessary.

In this long journey that lasted for more than ten years. Xiao Yu plans to build a few more city-level spaceships with the flesh and blood of alien beasts as the main body, and at the same time, small and medium-sized spaceships at the county, township, and village levels will also complete part of the upgrading and transformation, changing from ordinary materials to Zerg materials.

At that time, Xiao Yu's overall combat effectiveness. It will be increased several times.

At this moment, Xiao Yu has not yet left the three-star system of the Sky Eagle, and through the telescope, he can still clearly see the mountains and mountains on the home star of the beast. Reminiscing about the years when I lived with the beasts. Xiao Yu was overwhelmed with emotion in his heart.

In space, traces of the war with the Zerg can be seen everywhere. There are Zerg stumps, there are spaceship wrecks. At this moment, they have been mixed together, either orbiting around the planet, or orbiting around the three Aquila, and their total number is as high as tens of billions.

Due to the instability of their orbits, it can be said that in the next millions of years, the Aquila three-star system will become a high incidence of meteorite impacts. On the home planet of the beast, meteor showers also occur frequently.

"In the bright night sky, surrounded by stars, countless meteors pierce the sky, that kind of scene must be very beautiful." Xiao Yu thought about it, and after looking back at the beast mother star again, he resolutely turned his head and refused to go back to take a look.

Xiao Yu has already crossed the orbit of Planet Three. After passing here, with the accuracy of the naked eye, there is no trace of the mother star of the beast. At this distance, Aquila III is still bright. Xiao Yu could effortlessly feel its liliang and majesty.

At this moment, Xiao Yu was still blown by its stellar wind. It would take more than a month of sailing for Xiao Yu to reach its stellar wind boundary and enter interstellar space again.

The day is coming soon. Xiao Yu's fleet officially announced that it had left the Sky Eagle three-star system and began to gallop towards the Sky Eagle Four.

Time passes slowly, and every second of time represents a distance of tens of thousands of kilometers being crossed. At such high speeds, Xiao Yu's spacecraft collided with the dense interstellar dust particles of the Aquila Nebula, resulting in a miraculous phenomenon.

Under the high-speed impact of the particles, a large number of X-rays are emitted. X-rays are accompanied by light in the visible range. This kind of light showed a faint pink, and the light of the light blue energy shield on Xiao Yu's spaceship was covered, and from a distance, it seemed as if Xiao Yu's spaceship had turned pink, which was very beautiful.

Looking at this scene, Xiao Yu was a little speechless in his heart.

"Pink spaceship? It's also a little hilarious. If it is seen by the otaku of the Earth era, I don't know how many fantasies will be born in my heart. It's a pity that although the spaceship is pink, there is no Lori in it, and there are just cold killing machines. There are also Lucca people who look at the aesthetics of earthlings in a strange shape. ”

Thinking of the Lucca, Xiao Yu drew a little attention and checked the scene in the two spaceships of the New Home and the Heaven again.

Since the time of the White Dwarf Alien Beast, all the Lukkas have fallen into a deep sleep, even the unmutated Lukka have been asleep. Because Xiao Yu didn't know when he would have a way to treat them, and the unmutated Lucas were generally unwilling to have too much age gap with their relatives, friends, etc., so, under this kind of social factor, they simply fell asleep, and they have not been awake until now.

Time, in the midst of Xiao Yu's busy construction work, slipped away quietly. In addition to several municipal-level spacecraft that have completed the transformation, the Xingtai and Handan are also undergoing busy renovation work. Ten years have passed in a flash. Xiao Yu's fleet once again approached the edge of the star, and after entering the stellar wind range of the Aquila Quad, the color of the spaceship finally changed from pink to normal, which made Xiao Yu a little embarrassed.

The Aquila 4 star system is made up of five stars, which are roughly divided into two groups, one of which is made up of two stars, and at this stage, they exhibit some of the characteristics of a binary star system, with two stars revolving around their common center of mass, and the remaining three stars are mixed together and moving chaotically.

These five stars were named by Xiao Yu in alphabetical order, the first star was called A star by Xiao Yu, the second star was called B star by Xiao Yu, and so on.

The two star groups formed by these five stars are called the first group and the second group by Xiao Yu.

In the Aquila four star system, while the first and second groups orbit separately, they also orbit around the common center of mass of the five stars. The five stars as a whole are orbiting the heart of the silver along with the Aquila Nebula.

The movement of stars is so complicated.

Together, these five stars form a stellar system that makes the brain swell when you look at it, but faintly seems to have some kind of internal law.

This stellar structure is not stable. It is very likely that one day in the future, one of the stars of the first group will be captured by the gravitational pull of the other group and join their group, or it may be thrown out by gravity after a period of operation, and lose this group structure.

In short, the movement of three or more star groups is very chaotic and irregular. Their orbits can only be predicted in a short period of time, and long-term predictions, at least Xiao Yu has no way to do it.

This means that all of a sudden, a star may change its orbit and start rushing towards Xiao Yu's fleet. Overall, the Aquila Four Star System is really not a good place to be nostalgic.

Even Xiao Yu had a little doubt about his trip.

"Such a place would have something to do with the grand unification theory?" Xiao Yu thought about it, slowed down the speed of the fleet again, and slowly drove towards these stars.

As the distance approached, Xiao Yu made an astonishing discovery.

In such a chaotic place, Xiao Yu unexpectedly discovered a planet. It's still a very small rocky planet, about the size of Mars.

"What a poor little fellow." Seeing this poor planet running slowly under the stars, Xiao Yu couldn't help but sigh in his heart.

In this gladiatorial arena of stars, not even stars can have stable orbits, let alone planets that depend on stars to survive. This poor little guy is destined to be kicked around by the stars, without a stable home. If you are unlucky enough, if you get too close to the star during a certain change of hands, you will be torn apart by the gravitational pull of the star.

However, judging from the fact that there is no large-scale asteroid belt in the Aquila four star system, it has most likely not been torn apart. Of course, if the material it was torn out was directly swallowed by the star, that would be a different story.

"Let's use this little guy as a foothold." Xiao Yu thought for a while, made a decision, and began to maneuver the spaceship, flying towards the poor little guy. (To be continued......)
