Upon receiving the news, Hu Yu also halted construction preparations, leaving only the energy sphere conversion work to continue. Now everyone is awaiting Academician Liu's results on space transfer. However, for the safety of Earth Two, Earth Two must return to the JD4 Planetary System as originally planned. Only after arriving at JD4 can a series of experiments be carried out. The return journey of 30,000 light-years will take approximately 17 years.
Hu Yu wasn't in a hurry. He was currently in the shadows while the Xuan Star Civilization was in the open. He could take advantage of this time to convert as many energy balls as possible. If the warship had been built ahead of time, he might not have had the patience to wait for the energy balls to be converted. Now that the warship project was on hold, he could only keep converting energy balls, emptying the planet's internal space, and storing steel. Once the design for the new warship was finalized, construction could begin immediately.
This is a planetary system 4,500 light-years away from the space vortex. To be precise, there are four planetary systems. Three of them are arranged in an equilateral triangle. Each system has more than 30 planets. The three planetary systems are three light-years apart and form a huge defensive ring, tightly protecting the fourth planetary system in the middle.
Within this vast planetary system, there are as many as 600 million warships exceeding 4 kilometers in length. Space-based weapons and interstellar mines are as numerous as those of the Wind Star Civilization, and perhaps even more.
The Mu Star Civilization, an Advanced Star System-Level Civilization, an older Star System-Level Civilization Wind Star Civilization, has been stuck at this stage for over 300,000 years, unable to step into the Small Star Sector Civilization stage.
The development of civilizations is always vastly different. Some civilizations can enter the Great Star Region Civilization within a few thousand years, while others spend hundreds of millions of years and are still stuck at the Planet-Level. Over the years, Hu Yu has traveled through the Milky Way and seen too many civilizations. It is common for countless civilizations to be trapped at a certain stage for tens of thousands of years. There are also a few civilizations that have gone from the emergence of intelligence to entering the starry sky in just a few hundred years. Their development has left everyone speechless.
However, rapid development is one thing, but whether one can survive is another. Rapid development does not guarantee survival in the universe; otherwise, there would be many Great Star Region Civilization throughout history.
Mu Star is an ordinary life-bearing planet with an extremely beautiful environment and a great variety of species. On Mu Star, there is a group of Many-Legged Beasts. They are over ten meters long, with eight pairs of legs in the back for walking and two pairs of sharp claws in the front for attacking and hunting. If such a creature were on Earth, it would be a fat worm.
The Many-Legged Beasts have existed on Mu Star for over 2 billion years. Their powerful bodies have made them the rulers of the planet, and they never have to worry about food. Mu Star has always been able to evolve a variety of delicious species for them to eat.
As the sun and moon alternated and the Mu Star evolved, the creatures on Muxing came and went, with only the Many-Legged Beasts remaining. For the first billion years, they did not change much, until one day, a supernova exploded 2,800 light-years away from Mu Star. 2,800 years later, the energy surge from the supernova reached Mu Star, and even after its long journey, the supernova energy surge still killed more than 99% of the creatures on Mu Star.
This also includes the Many-Legged Beasts. The surviving Many-Legged Beasts remained unchanged, but their offspring underwent subtle changes. After millions of years of reproduction, the Many-Legged Beasts finally evolved intelligence, and the ancestors of the Mu Star Civilization were born.
With the development of intelligence, the Many-Legged Beasts began to gradually develop towards civilization. It took them more than 800 million years to finally enter the early stages of technological civilization. The Many-Legged Beasts who entered the early stages of technological civilization called themselves the Mu Star Race. Like humans, the Mu Star Race also experienced a long period of war. However, unlike humans, whose wars promoted technological development, the Mu Star Race's wars seriously hindered technological development.
More than 100 million years later, the Mu Star Race finally achieved unification and began to advance towards Stellar-Level Civilization. However, the Mu Star Race, accustomed to simple thinking, still made slow progress, but it was indeed much better than before.
It took them 100 million years to break through to the advanced stage of the Star-Level, and another 80 million years to finally reach the advanced stage of the Star System Level. They have been stuck at this stage for 300,000 years now. In the words of the leader of the Mu Star Race, the development of the Mu Star Race to this point is truly a miracle. When they can break through to the Small Star Region is not something they need to worry about at all.
100,000 years ago, a mysterious fleet arrived on Mu Star, and a deal was struck. The mysterious fleet promised to grant them the technology to reach the level of Small Star Sector Civilization as long as they could cultivate insects of a sufficient level.
The leader of Mu Star also knew that the Planetary-Level Civilization to Star System-Level Civilization was an improvement in energy level, but the transition from Star System-Level Civilization to Small Star Sector Civilization was a completely different matter, involving the understanding and application of space. Even if their civilization were to reach the Small Star Sector Civilization in hundreds of millions of years, it was not certain that they would be able to do so.
To feed the Insect Race, the Mu Star Civilization's fleet moved hundreds of planets from the surrounding area. At the request of the mysterious fleet, the Mu Star Civilization reduced its sphere of influence, moving all of its original dozens of planets to the vicinity of a single star. The other three stars were all planets used for raising life.
It took hundreds of years just to terraform the planets for these creatures. After the planets were terraformed according to the plan provided by the mysterious fleet, the mysterious fleet transported two more planets from somewhere. These two planets were inhabited by bipedal creatures, and they reproduced very quickly. In just a few thousand years, these bipedal creatures had spread to more than a hundred planets.
These creatures are also highly intelligent, and are likely civilized beings that the mysterious fleet plundered from somewhere. The leaders of Mu Star also inquired with the mysterious fleet and were told that they were indeed civilized beings. Feeding the Insect Race with civilized beings yields better results. In order to achieve Small Star Sector Civilization, the Mu Star People do not care about these things at all. They impose various restrictions on two-legged creatures, and apart from providing a comfortable life, no other inventions or creations are allowed.
It wasn't until they clashed with Luo Zhigao's fleet that Mu Star People realized the creatures he was raising were almost identical to those of this civilization called humans. Mu Star's leader vaguely sensed that things were not simple, especially since this human fleet had leaped from Stellar-Level Civilization to a high -Star System Level- level civilization in just a thousand years. The massive fleet easily swept away one of their Insect Race bases and transport fleets, which gave him a deep sense of crisis.
The leader of Mu Star hurriedly relayed the message to the mysterious fleet. If the mysterious fleet did not take action, the human fleet, which resembled a domesticated creature, was very likely to attack the Mu Star base. Even if Mu Star could currently withstand the attack thanks to its strong defenses and the fleet it had built up over the years, given the speed at which the human fleet was developing, they would definitely surpass the strength of the Mu Star Civilization in a few thousand years.
