The Yatanian Rat and Tristan Cats were originally from the same planet. They have been mortal enemies of each other since the stage of ignorance, and they will sacrifice their lives to fight when they meet.

During this period, they each had an advantage, but they could never eliminate the other party. Even if they thought they had killed all the rat or cat people, they would find a fish that had missed the net in a few decades.

Moreover, cat and mouse are very capable of fertility. As long as you give enough time and environment, you can quickly reproduce enough ethnic groups.

"Wait!" A big man frowned and questioned: "If this happened in the agricultural society, I wouldn't think there was any problem, but they have entered the space age with highly developed industries. If they really want to destroy a certain race..."

"The strange thing is here!" Another expert quickly explained: "According to what we know, both Yatania and Tristan have just entered the industrial revolution, which is equivalent to our Blue Star in the late 19th and early 20th century, and even the power system has just been used for a short time!"

When everyone heard this explanation, they were in amazement!

Just the civilization that has just entered the industrial revolution? Aren’t they able to use super-light speed technology to surround the starry sea?

This is not a joke!

"How is this possible?"

A master of a certain science college thinks that whether this investigation report is problematic is simply contrary to scientific common sense!

If the Blue Star humans had not had black technology masters, they would probably have not been able to master anti-gravity engine technology in hundreds or thousands of years, let alone super-light navigation technology such as curvature folding transmission.

The expert smiled bitterly and said, "According to the information provided by Tristan Cats, they have learned super-light navigation technology in primitive society!"

This explanation is even more incredible, but the expert immediately waved his hand to play a holographic video, explaining how aliens can sail superluminal speed through a brief 3D simulation demonstration.

Judging from the video, if an alien wants to sail superluminal speed, he has to enter the subspace, but if he wants to enter the subspace, he has to use some kind of space crystal, and he can easily enter and exit the subspace through the navigator's meditation resonance.

This kind of crystal is very rare, and after entering the subspace, it will cause certain losses to the crystal, and it will likely disappear after multiple uses.

"Aliens discovered this kind of crystal when they were in primitive society, and then the wizards in the rat, human and cat group quickly discovered how to use crystals, and could even enter sub-space and cross the starry sky with their physical bodies and reach other planets!"

"Impossible!" When everyone heard this, they couldn't help but feel shocked: "Whether they are rats or cats, they don't look like they can survive in a vacuum!"

"According to their description, subspace is a very strange place. It will not be hurt at all when the space crystal works, and you don't have to breathe or eat. It is as if you are in a dream, but you can easily get lost!" The expert explained.

It turns out that subspace is not a space in the physical sense, and it does not even exist in reality. As long as it resonates with the space crystal, it can enter the subspace within a certain period of time.

"This superluminal navigation technology is a bit different from curvature folding teleportation!" someone whispered.

"It is true. According to their scientific theory, space and dreams are two sides. As long as intelligent life enters the dream through space crystal resonance, it can have a way to move countless light-year space!"

"Because of this, they can sail superluminal speed in primitive society. As long as there is no danger from the place where they come from subspace, not high altitude seas or starry sky, etc., there is always a chance to successfully reach other galaxies..."

Therefore, the racial conflict between rat and cat man has never been resolved. It is because of the space crystal that these two races are unable to annihilate each other because there are more than ten planets in their galaxy suitable for survival and reproduction. As long as one or two run to other planets through the crystal, they are likely to hide.

When it develops decades later, the rat or cat man can fight back. Then these two races have been fighting for millions of years, but the technology of both sides cannot climb to a high point. The technology will often regress for hundreds of years due to war, and then racial civilization will continue to stand still.

"I see!"

Everyone can finally understand why these aliens have not developed higher technology for millions of years. It turns out that not only did they have multiple intelligent races on the same planet, but they also mastered subspace navigation technology too early, which allowed them to enter the space age directly.

The racial war between both sides has lasted for a million years and cannot end, which has dragged down the development of scientific and technological civilization on both sides and has always been in the original scope.

"If the other party's technology is in the early stages of the industrial revolution, any country on our Blue Star can crush the other party!"

"Yes! It's true that we can rely on large-scale productivity to win if we conflict with them."

"But you should be careful and be careful. You should send an exploration spacecraft to take a look first, so as not to cause unnecessary losses!"

The bigwigs of the flower planting family quickly made a decision and ordered the Expeditionary Fleet to continue to explore the alien origin galaxy based on the star map coordinates provided by Tristan's Catman, but they must be careful not to let the rat man discover it.

A few days later, the news from the fleet ahead shocked the insider directly.

It turned out that the information provided by Tristan Catman was not a problem. The exploration fleet discovered more than a dozen habitable planets in the designated coordinate galaxies. They all had different ecological environments on them, but they all looked very suitable for human habitation.

Among them, the planet originating from cat and mouse is one quarter larger than that of Blue Star. The atmosphere composition on it is the same as that of Blue Star hundreds of millions of years ago. The oxygen ratio is very high, but the planet's gravity is equivalent to that of Blue Star. It is estimated that there are large holes inside the planet.

"This origin star has an ocean with an average depth of about two thousand meters, covering more than half of the total surface area. The continental plates have very lush primeval forests. Obviously, even their parent star has not been fully explored..."

"This is an inevitable thing, because they entered the space age too early, which made them not very developed in the planet. In addition to their parent planet, there are more than a dozen planets waiting to be developed!" Some experts explained.

Faced with such rich resources, all the big guys were a little excited at first, but they quickly calmed down. After all, there were people in the hands of the rabbit, such as the Horse Galaxy, and there were more than ten planets on it that could allow humans to live in.

However, when comparing the human-horse galaxy with the origin of the cat, mouse and human, soon even the big guys who are not experts felt something was wrong, because these two galaxies look very similar. Except for the human-horse galaxy, the orbits of other planets are very similar.

"Is this a coincidence? It doesn't look like it!"

"Can it be like this all super-large planetary systems? Because they need to satisfy the existence of multiple planets, there is a certain physical law inside?"

Especially the planets on the human and horse galaxies, the natural environment on them is not only very similar to Blue Star, but also the planet's animals and plants grow very lushly and have very rich resources to utilize.

But what is strange is that these planets do not have traces of intelligent life. No matter how you look at it, it is a bit strange. If it is a planet like Blue Star, at least there will be signs of primitive human activities.

"Academician Li, what do you think?" the boss suddenly asked Li Maoye.

Li Maoye always felt inconsistent with the human star. Now he finally knew what the problem was, so he spoke: "These two galaxies should be formed artificially!"

Everyone suddenly became silent. This answer was indeed unexpected, but it was very reasonable to Li Maoye's words. After all, he was a senior alien expert.

Or maybe you are an alien yourself, so it is normal to know something!

Li Maoye paused for a moment and quickly explained: "I have checked the genes of rat and cat people. It seems that there is no human factor, but in fact it is designed into a perfect and stable genetic structure from the beginning, and then the coincidence of the human and horse galaxies..."

"I boldly infer that these two planets are actually experimental sites for higher civilizations in space, but one of its galaxies is still conducting experiments, and the other galaxies stopped a long time ago!"

After hearing this explanation, the big guys and academicians and experts present finally felt a crisis. It turned out that the rat, cat and human beings they encountered were not real aliens, or they were not the higher alien civilization they expected.

"Well, then we have been exposed to higher aliens?" said one of the experts.

This is obviously obvious. Li Maoye did not answer, and the others quickly understood this point, so the bosses of the relevant departments decided to recall the expeditionary fleet immediately and let them retreat to another galaxy first, and even the strongholds of the human-horse galaxy had to give up immediately.

Just kidding, building a military base in someone’s experimental site is simply a provocation!

Although humans have not seen the creators of these two galaxies so far, they already understand how big the technological gap between the two sides is. After all, they are advanced civilizations that can create galaxies at will, and they are definitely not comparable to those of today's humans.

Li Maoye originally wanted to stop the decision of the Great Retreat. After all, human beings have been exposed to the eyes of higher civilizations, and it is too late to run even if they turn around.

But if you think about it carefully, higher civilizations will definitely not stare at the whole process in the cat and mouse galaxy and human race galaxy. They must come to collect data every once in a while, just like him in the Cat Star Laboratory, and they also assigned them to the researchers below to do it. Then he will collect data every day or every few days.

"It will definitely not be discovered for a while, but it will be hard to say in a few years or more. If you are lucky, the higher civilization behind this may no longer exist, just like the Martian civilization!"

"On the contrary, the space crystal is interesting, or should I apply to the above for one to study?" Li Maoye thought to himself.

In fact, he suspected that the space crystal was the high-energy crystal he was looking for, but he had not seen the real object yet and could not judge it. If it was really a high-energy crystal, he would definitely have to make some to use it.

However, the submitted application was not approved because these space crystals are very precious and extremely unstable.

On each alien spacecraft, there is a navigator who uses space crystals. Because they need to resonate with the crystal at any time to enter the subspace, the crystal and the navigator are a whole.

"In other words, the crystal is there, and the person is there, and the crystal will die if it consumes it?" Li Maoye asked.

"That's right! But you can replenish the crystal when there is still some, and the way to replenish it is through eating!" Tristan Catman explained.

After the navigator or candidate navigator eats the space crystal, a colorful crystal will soon be generated on his forehead. Just meditate to pull the surrounding things into the sub-space. The range and weight of the influence are determined by the navigator's own ability.

"No wonder your spaceship is either a board ship or a biological insect spaceship. It turns out to be to reduce weight? And there is no large spaceship, because this will be limited by the navigator's talent ability!"

"Uh, that's true!"

According to the Cat Man's data records, every intelligent life can resonate with the crystal, but the scope and weight of the influence must be improved through training. Then space crystals are extremely scarce, and ordinary people will definitely not be able to access them.

Li Maoye thought about it carefully and suddenly asked: "From the confession of the Rat Man prisoners, they were chasing you for the confidential documents on Princess Liya. Is this document related to the space crystal?"

The cat man's explanation was stunned when he heard this, not knowing how to answer.

"Haha! I shouldn't ask you, but the princess." Li Maoye patted his bald head and said.

In fact, he didn't need to ask himself. After receiving Li Maoye's speculation, a psychological expert immediately went to Princess Liya to talk to him and quickly got the relevant information.

It turned out that the Tristan Empire discovered a space crystal mine in a galaxy. This crystal has long become very precious and scarce after millions of years of consumption. Therefore, being able to own a high-yield crystal mine is equivalent to having a decisive battle ace.

Even though the Yatanian rat people had much larger populations than the cat people and had a strong development advantage in the era of the Industrial Revolution, when they learned that the Tristan Empire had discovered the crystal mine, the upper class of the rat people could no longer sit still.

For both of them, space crystal is a military necessity. If there is no crystal or the crystal is not used enough, it will be easily defeated by the other party.

For millions of years, the other party has no choice but to have the cat and mouse people. It is because whoever owns the space crystal is basically invincible, and even if he can't beat the other party, he can easily turn around and escape.

Therefore, the Yatanian rat man must obtain the coordinate address of this crystal mine, and only Princess Liya, who is responsible for transporting the crystal, knows this confidential information.
