Time is the most meaningless existence in the universe, and often a trip between galaxies can take hundreds, thousands, or even tens of thousands of years.

Along with a long period of time, there is loneliness, deep loneliness, loneliness, boundless loneliness. For more than 10,000 years, there was no one to communicate with, no majestic and magnificent mountains and rivers to play, only the endless dark sky.

But this situation did not appear in Jin Ye and Xiao Yu, it was rare to have such a long and comfortable time, Jin Ye naturally chose to retreat and cultivate, or do some small experiments to design and manufacture some competent equipment.

Xiao Yu was also not idle, at the beginning when he looked at Jin Ye, sometimes he would have the idea of letting Jin Ye find a woman and reproduce the entire human race, but because the earth exploded, there was no woman, so Xiao Yu had to dispel this idea, and Jin Ye escaped.

After that, Xiao Yu recovered from the slump of leaving the solar system, regained his spirit, and had the desire to explore.

Xiao Yu began a star mapping program called Qunying Canglu, by locating stars and pulsars in the universe to determine his position in the universe relative to the solar system.

At the same time, research on projects such as over-distance communications, anti-gravity technology, and new-generation spacecraft engines has also been put on the agenda. The study of physical theory is also in full swing, and even the huge amount of computing has scheduled the calculation schedule of the main computer to three hundred years later.

Jin Ye and Xiao Yu were in this full state, and time slowly slipped away. Since leaving the solar system, Xiao Yu has not encountered any stars or matter.

This situation has been maintained for 600 years.

Six hundred years later, Xiao Yu's Water Blue Star fleet arrived at a place.

Here, there is the Oort cloud, a light-year distance from the Sun. Looking at the Sun from here is better than looking at Sirius from Earth. The sun, at this time, has truly become an ordinary member of countless stars.

It was also in the Oort Cloud that the Blue Star fleet finally had the opportunity to contact and capture meteorites to replenish the supplies and energy in the fleet.

After a short pause and replenishment of resources, the entire fleet once again set out on a long voyage.

As for Xiao Yu, after seeing that Jin Ye did not age with time, he no longer worried about Jin Ye's lifespan for the time being.

Countless times have passed in a hurry, and more than two thousand years have passed since Xiao Yu left Ooryun.

Sixteen hundred years later, Xiao Yu fell into a state of energy shortage, and if the spacecraft was not necessary, it completely relied on inertia to sail, turning off all unnecessary energy consumption, and at the same time, all the replacement parts in the fleet's reserves were used up.

As a result, over the next 400 years, 50 village-level spacecraft were abandoned one after another. The parts on them were removed and installed on top of the rest of the ship, replacing their damaged parts. These fifty village-level spaceships are only an empty shell, and without their power system, they will not have the ability to continue to follow the large army, and Xiao Yu will not have the ability to carry them extra. There is no choice but to abandon them, although the shells of these ships are all new type of Edelman-like alloys, and it is a pity to abandon them, but there is no choice at this time.

And these abandoned ships can only follow a fixed trajectory, floating in the endless universe forever.

The entire voyage has covered 40 percent, a distance of four light years. During this period of sailing, Jin Ye's photonic computer, anti-gravity technology, and over-distance communication technology have all made breakthroughs, but there are not many breakthroughs in the energy weapon technology and basic physics that the third-level civilization can master.

Not to mention the grand unification theory that only a fourth-level civilization can master.

However, Xiao Yu believes that it is only a matter of time before he reaches the Tianyuan 4 galaxy and obtains enough material to replenish and build a large particle collider around Tianyuan 4.

The endless voyage continues. In the fleet, the village-level spaceship that played the vanguard suddenly detected a little unusual fluctuation, which immediately attracted Xiao Yu's attention.

It was a radio wave with some kind of pattern. Xiao Yu can confirm that this radio wave was not sent by his own fleet.

But because the duration of this radio wave is too short, Xiao Yu has no way to locate its emission source. After thinking about it for a while, Xiao Yu made a decision.

This burst of radio waves has obvious traces of wisdom and civilization. Specifically, it has three cubic repeat bands and five double repeat bands, and there seems to be some logical connection between the repeating bands.

Although there is no way to locate the emission source of this radio wave, with the current information, Xiao Yu can be sure that it is not far away from him.

Xiao Yu's mood became tense, this was probably the first time that human beings had contact with an extraterrestrial intelligent civilization. And if radio waves are received in such a void, it can prove that this alien civilization has at least gained the ability of interstellar voyages.

Soon, Xiao Yu informed Jin Ye of the news in retreat, and at the same time, all the weapons had been warmed up and were ready for battle.

"What should we do?" Xiao Yu asked Jin Ye when he saw Jin Ye coming.

Unlike Xiao Yu's own hasty space voyage, this unknown alien civilization is likely to have reached a speed of five percent of the speed of light before starting the space voyage.

This represents an insurmountable technological gap, and Xiao Yu will be a lamb to the slaughter who has no ability to resist in the face of this technology.

"Don't move, don't emit any radio signals, we'll wait and see. Jin Ye thought for a moment and said.

Although in the original world trajectory, Xiao Yu also encountered an alien civilization and defeated them, but at this time, with such a variable as Jin Ye, how will the butterfly's wings affect the whole world?

All this is still unknown, so it is impossible for Jin Ye to be uncautious.
