What awaits Xiao Yu in front of him will be a long voyage of more than 6,000 light years, because of the influence of several large gas clouds and neighboring star clusters, Xiao Yu cannot see the sun from this place, no matter what band of detection means, the sun cannot be seen. But Xiao Yu knew that the sun was there, quietly orbiting around the silver heart behind this darkness.

That was Xiao Yu's hometown. All Xiao Yu has to do now is go home.

The vast universe is like an endless sea, and the Hope spaceship is the Ye Bian boat that carried Xiao Yu home.

"My people, I'll take you home." Looking at Zhang Shengya's calm face, Xiao Yu muttered to himself.

The Hope spacecraft is speeding forward at nearly one hundred and fifty times the speed of light. Xiao Yu never cherishes any scenery on the road, no matter how spectacular and beautiful the natural phenomenon is, Xiao Yu can't stop. After seeing enough of the prosperity of big cities and experiencing the ups and downs of life, the small mountain village that is partial to a corner and gives birth to itself may be the best place.

The solar system is very inconspicuous, but it is Xiao Yu's hometown.

The death of the associated ghost clan was a big blow to Xiao Yu, and it was not an exaggeration to say that it made Xiao Yu a little depressed. It was during this period that Xiao Yu first doubted his persistence.

"Can I really defeat the Sweeper civilization? Can I really beat Neutron Battlestar? Xiao Yu pondered silently, "Tens of billions of warships have perished under the neutron battle star in this way, and even the ghosts have died. ”

There has never been such a moment when Xiao Yu's situation was so dangerous, not even the time when he had just left the earth. At that time, after all, there was Taihao civilization secretly taking care of himself, and under the care of the so-called luck, he was not as unlucky as he is now. And now, the Taihao Alliance is all dead. The companion Ghost Clan died. The death of the companion ghost clan not only deprived him of an absolutely loyal and powerful comrade-in-arms, but also pulled his luck to the lowest level.

The inexplicable encounter with the neutron battle star led to the destruction of the Sun spacecraft, the curvature navigation engine inexplicably malfunctioned, and in the battle with the third-level beast, the conventional drive engine also inexplicably malfunctioned, resulting in more serious damage to the hull, this series of facts are telling Xiao Yu that you don't have much time left.

"Even if I die, I will die in my hometown, in the solar system." Xiao Yu thought silently.

Time slipped away slowly, and twenty years passed. Xiao Yu has sailed a distance of about three thousand light years. Half of the distance has been crossed by Xiao Yu. Luckily, during this time, the Hope spacecraft did not encounter any accidents.

At this moment, the Hope spacecraft has broken away from the curvature space and is approaching a planet in a conventional way. The long journey of 3,000 light-years has almost depleted the energy reserves of the Hope spacecraft. Xiao Yu must take a break here.

It's a lonely, rocky planet that orbits around a red dwarf. Red dwarfs are already very dim. The distance between the rocky planet and the star keeps it in darkness all year round. It's cold and lonely. There were no signs of life, just craters of large and small craters. Under the illumination of Xiao Yu's optical equipment, there are many bright reflection areas on the surface of the planet. Xiao Yu knew that it was solid hydrogen or solid nitrogen, and solid methane and the like. Because the temperature was so low, these things had to come in solid form.

Xiao Yu descended on the daytime side of this planet. As long as there are planets orbiting stars, there will be day and night. It's just that this kind of day-night alternation is not the same as the traditional day-night cycle. It's daytime, but the sky is still full of stars, and the planet's surface still needs lighting to see things.

Here, there is basically no difference between day and night.

Here is an insignificant corner of the Milky Way. For billions of years, perhaps no life has ever set foot here. There are many such places in the Milky Way. The Milky Way is so big that even with Xiao Yu's ability in his heyday, it is impossible to fully explore.

On this distant, cold, lonely, and dark planet, Xiao Yu completed his material replenishment. The conventional propulsion engine and the anti-gravity engine turned on at the same time, and the Hope spacecraft slowly left the planet. The thruster's tail flame left the planet with the only trace of a sapient being, which could last billions of years if nothing else.

Xiao Yu once again entered the curvature space. If all goes well, Xiao Yu's fuel will be just enough to support Xiao Yu to reach the solar system. Twenty years only.

Shenzhou Civilization, Sweeper Civilization, Guardian Civilization, Taihao Alliance, Three Strange Beasts, these terms have a dreamy sense of being separated from another world in Xiao Yu's view, as if those things happened in the previous life. For Xiao Yu now, it is difficult for him to be stirred by these nouns and the stories that happen between them. Now Xiao Yu just wants to go home and return to the place where he was born.

About nineteen years later, Xiao Yu arrived at the location of the original Tianyuan four star systems. The Hope spacecraft broke away from the curvature space and slowly moved forward here in a conventional way, carefully observing this place that Xiao Yu could call his second home.

Xiao Yu will never forget the stories that happened here, but the real scene always matches the memory. The vibrant, passionate star is gone, replaced by a nebula about half a light-year in diameter that is still spreading. Only the little radiation that still remains here can be deduced backwards from the distant past.

Tianyuan Si has disappeared, this is something Xiao Yu has known for a long time, but now that he sees the remains left by the shattered Tianyuan Si, Xiao Yu is still a little sad in his heart. The three planets Tianyuan A, Tianyuan B, and Tianyuan C have also disappeared long ago. Xiao Yu knew their end, after Tianyuan Four was detonated by the Guardian Civilization, the disappearance of gravity would cause the three planets to fly out directly along the tangent of their orbits, as for where the target of the flight was located, Xiao Yu did not know. But Xiao Yu knew that they must have entered the vast universe and become wandering planets that have lost their main star and can only wander in the galaxy.

It's a sad ending, but they're still lucky compared to Earth's ending.

After staying in the original site of Tianyuan Four for a while, Xiao Yu once again embarked on the journey. At this moment, it is only about ten light-years away from the solar system, and my hometown is right in front of me. The sun had turned into a bright star in the sky, where it emitted a faint yellow light.

Xiao Yu sighed slightly and entered the curvature voyage. Xiao Yu still remembers that when he first left the solar system, it took him more than 6,000 years to complete the first interstellar voyage, and now, it only took Xiao Yu less than a month to re-walk this journey.

Coming and going, these two journeys, Xiao Yu has a completely different state of mind. When he left for the first time, although Xiao Yu was confused about the future and fearful of the deep universe, he was more excited about exploring the unknown. This time I returned, but there was no pride in my heart, and there was a sense of death in my heart.

Xiao Yu feels like a teenager who left his hometown to go outside to wander in the world of flowers, experienced all kinds of thrilling or difficult things, and finally succeeded in his career, and then a major setback directly knocked him back to the starting point.

This trip, not only did not return to the hometown, but there was a sense of looking for psychological comfort and escaping danger.

Eighteen days later, Xiao Yu arrived at the Oort Cloud region of the solar system. This is the outermost boundary of the solar system, which is a light-year away from the sun.

The Sun has become the brightest star in the sky, brighter than Venus from Earth. But above the ecliptic plane, when you look at the sun, it is much darker. Xiao Yu knew that this was because of the obscuration of the Earth's asteroid belt, which had been reduced to fragments.

It has been almost 100,000 years since he left the solar system, and after 100,000 years, Xiao Yu finally returned to the solar system again. 100,000 years has passed in a hurry, which is enough time for many vicissitudes of life to occur, but on an astronomical scale, 100,000 years is only a moment.

Xiao Yu didn't stay here for too long, only stayed for less than a day before entering the curvature voyage again. A day and a half later, Xiao Yu sailed out of curvature again and stopped next to a planet.

This is the Lost Star. The name Lost Star was given by Xiao Yu. It is the outermost planet of the solar system, and it has never been explored and seen by humans for a long period of time. But Xiao Yu found it.

The Lost Star remained its original form, with no changes other than a little more crater on it. It's just that it seems to have suffered a little more impact recently, and Xiao Yu has seen a large number of new craters on it. Xiao Yu knew that a large part of the culprits responsible for these craters were fragments of the original earth.

After staying for a day, Xiao Yu embarked on the journey again. Xiao Yu did not adopt the curvature navigation method, but used the conventional navigation mode to move forward. Ahead is the range of the heliopause, beyond the heliopause, Xiao Yu really entered the scope of the solar system. (To be continued......)
