A fleet can easily move a star, but it cannot move a black hole formed from the remnants of a star. Compared to a star, a black hole formed from star matter has a much smaller mass, but such a black hole is like a nail firmly nailed into space, and no matter how powerful the fleet is, it is useless.
Moreover, these black holes are among the smallest in the universe, a mere drop in the ocean compared to the black hole at the center of the Milky Way. It seems that using stars to create black holes is not a viable approach.
Ten years have passed in the blink of an eye, and Academician Zeng could only regretfully inform Hu Yu.
"General, I'm sorry, we cannot drag the spatial vortex into the territory of the Xuan Star Civilization."
"Never mind, I already expected this outcome."
"Come back, General."
"Well."
"General, do not be discouraged. Although we cannot climb to the top by standing on the shoulders of the Xuan Star Civilization, our development over the years has been rapid. We believe that surpassing the Xuan Star Civilization is only a matter of time."
"Okay, we're getting ready to head back too. See you on Earth Two."
"Bon Voyage!!!"
A thousand years have passed, and it still ends like this. Hu Yu had no choice but to lead his fleet to set sail. This massive fleet, composed of 80 million Grim Slayer, looked imposing, but compared to the Xuan Star Civilization, it was like comparing a fire poker to a tank or cannon.
Even though everyone felt a great deal of resentment, that was the reality. Under normal circumstances, it was very difficult to challenge someone of a higher level. Even the Wind Star Civilization's success had a large element of luck, plus years of infiltration and cultivation within the Wind Star Civilization's territory.
The fleet had been quite lucky to have come this far; otherwise, it would have been destroyed long ago. Life is always full of regrets, but this time, he figured he had learned something new. He finally understood the difference between a mature, settled civilization and a nomadic civilization like theirs. Hu Yu comforted himself and everyone else with this thought.
More than half of the stars in the Milky Way are binary or multiple star systems. When you look into the deep sky at night, those two dots are often not a single star, but two, three, or even more. Binary systems are the most stable in multiple star systems, but for planets, all multiple star systems are hell and disaster.
For life, multiple star systems are generally a dead end. However, there are always exceptions. About 7,000 light-years away from the JD4 Planetary System, there is a binary star system. The two stars have roughly the same mass, about three times that of the Sun, and are considered relatively bright stars in space.
Two stars orbit each other, and around them are six planets. These six planets are not much different from other planets in the Milky Way. If we had to pick out a difference, it would be that none of these six planets rotate, and all of them have the same angular velocity.
All six planets are tidally locked, forming a perfect isosceles triangle with the two stars, a triangle that has remained unchanged for countless millennia. Like the relationship between the Earth and the Moon, where the Moon has lost its rotation and always presents one side to Earth, these six planets are similar. Tidally locked celestial bodies are common in the universe, but the simultaneous tidally locked nature of multiple planets within a single star system is likely unique in the entire Milky Way.
With this stable structure, life is provided with a relatively stable environment. Life is fragile. Hu Yu has come into contact with so many individuals from various civilized races. Apart from the Insect Race, the individuals from other civilizations are all very fragile. To put it bluntly, a sharp knife could almost easily kill every civilized creature Hu Yu has ever seen.
Even a tree-man race like Ninety-Seven is only relatively strong, far from being as powerful as an ordinary robot. Perhaps the universe is fair, giving civilized beings intelligent brains but fragile bodies. However, intelligent brains can protect fragile bodies through various means.
In this binary star system, the side of a planet facing the star is constantly exposed to the scorching heat of the sun, especially the sunlit sides of Planet Two, where the temperature is always above 600 degrees Celsius. However, the sunlit side of Planet Four drops sharply to a few tens of degrees Celsius because the first three planets block most of the intense sunlight.
Life emerged on the dark side of Planet Two and the light-facing side of Planet Four at almost the same time and evolved to the civilization stage simultaneously. Although one civilization was born in darkness and the other in sunlight, their biological structures were not significantly different. The civilization on Planet Two had also evolved to develop in the light, since darkness is definitely not an ideal environment for civilization.
Planet-Level stage, the two civilizations became aware of each other's existence by launching satellites and established communication channels. Since their appearances were not significantly different and met each other's aesthetic standards, coupled with the trust built up through long-term exchanges, their communication became increasingly smooth, eventually leading to the exchange of technologies.
Two hundred years ago, they stepped into the threshold of Stellar-Level Civilization. The two sides could finally travel to each other's planets relatively easily. Unlike other civilizations that were in conflict, the two civilizations coexisted peacefully, which was a rare occurrence in the Milky Way. Perhaps it was the trust they had built up through long-term communication that played a role, or perhaps it was their gentle nature that prevailed. The two planets were like two homes for these two civilizations.
As always, Hu Yu liked to stand by the porthole of the warship and gaze at the starry sky. Although he couldn't see much while sailing at high speed, this habit had never changed since Hu Yu first realized the mystery and vastness of the starry sky.
A soft "thump" echoed through the warship.
"Another meteorite?" Hu Yu wondered. The fleet was moving at high speed. There would be small spaceships five light-years ahead as scouts to clear the way. Because the fleet was moving too fast, unless there was a large celestial body or the fleet of another civilization ahead, the scout spaceships would not transmit information to the fleet. Some small meteorites or other fragments would not have any destructive effect on the Grim Slayer.
This minor impact was clearly overlooked or missed by the Vanguard ship. The Vanguard ship was also traveling at high speed, only pausing for a few seconds every few light-years to scan the surrounding airspace. Therefore, many small particles would not be detected at all. Small particles would not cause damage to the Grim Slayer, so there was no need to scan them carefully.
However, the Grim Slayer's sensors analyzed the cause of the impact and found it to be atomic fission energy. This surprised Hu Yu. How could there be atomic fission energy? Atomic fission energy is not common in the universe. On the contrary, it is often used by intelligent beings in their early stages.
