The previous six million warships, plus the current fifteen million, can be said to be a very heavy gift.

However, while giving this gift, Lin Yifan also gave Princess Hongyu a problem. With a population of 15 billion, this is not a small number.

Princess Hongyu not only has to arrange them properly, but also has to block the news. Until the last moment, she could not let the outside world know that she had captured so many powerful officers and soldiers.

The reason why Lin Yifan gave Princess Hongyu this problem was also to test Princess Hongyu's ability to deal with big things.

However, this is not the most important reason, the real reason is that Lin Yifan does not want to kill. 15 billion people, if they are all killed, Lin Yifan feels that he will become a demon.

He didn't want to be a bloodthirsty demon himself, and even if they were all enemies, he couldn't do a crazy slaughter.

If Lin Yifan really did that, what difference would there be between him and those overlords who bullied the weak.

In fact, Princess Hongyu could also guess Lin Yifan's thoughts, if it were her, she would not have been able to kill all these 15 billion people.

Anyway, there are a lot of colonial stars that the Hongyu Empire is developing, and it is not a small labor force to transfer these people over.

It has been four days since the fleets of various forces entered the space-time wheel star system. For four days, the lords of each country could not contact their fleets, which made them suspicious.

Lin Yifan was also worried that those forces would send a fleet to search here again, so he left the drone unit behind to protect Hongyu's officers and soldiers to complete the transfer task.

It took about ten days to transfer the enemy warship and the prisoners. And the wreckage of those battleships has not yet been salvaged.

During these ten days, the drone unit has been protecting the logistics troops of the Hongyu Empire.

During this period, some fleets of forces also came, but the ending was the same, except for adding some wreckage to the space-time wheel star system.

The harvest this time is huge, equivalent to the minerals that the Hongyu Empire has been mining for decades. With these materials, the development of the Hongyu Empire will be accelerated by several decades.

When he saw the video of the battleship of the extragalactic system before, Lin Yifan had a sense of crisis. He knew that there were many big forces in the Dapeng River system that were colluding with the overlord forces, and it was only a matter of time before they invaded the Dapeng Galaxy.

Between the various hegemonic forces, in the near future, there will also be a thrilling war.

Lin Yifan wanted to make his strength rise quickly before they made a move. At the same time, he also wants to help Princess Hongyu enter the ranks of top civilizations in the shortest possible time.

The battle of the space-time wheel star system was Lin Yifan's first step to weaken these vassal forces. Next, he will borrow the hand of the Hongyu Empire Alliance to completely eliminate these forces.

The top forces of the extragalactic galaxy may have many forces involved in the Dapeng system. They want to annex the Dapeng River system, and even if they can't, they have to stir it into a pot of porridge.

There are many mineral-rich star systems in the Roc River system, as well as countless meteorite and asteroid belts. In some places there are also huge and boundless clouds of dust, which are also a huge mineral treasure.

The main reason is that the Dapeng River system is relatively far away from the territory of the top hegemonic forces. Those top civilizations can secretly develop here, and they won't let those top overlords find out.

When they have enough strength, they can compete with the top hegemonic forces. At that point, the universe will be plunged into darkness again. Countless people will be ruined, and many living galaxies will be destroyed.

In the past month and a half, all forces have been trying their best to scan the situation in the space-time wheel star system. However, no matter how advanced the reconnaissance ship they sent, they could not detect the situation inside.

The space-time wheel star system is now completely a black hole, and fleets can go in, but they can't come out.

The news spread quickly, and all the forces in the Dapeng River system were very shocked. However, there are also many forces who are very curious about the Spacetime Wheel and want to go in and find out.

But thinking that none of the warships that had entered had come out of it, these curious lords dispelled this idea again.

For a time, various legends circulated in the space-time wheel star system. The forbidden land of death, the forbidden area of life, the relics of ancient civilizations, some people say that the top civilizations of ancient times are hidden in the star system.

Legend has it that ancient civilizations have not disappeared, and their descendants have always developed in the space-time wheel star system. Hundreds of thousands of years have passed, and their technology may have already reached the god level.

Those fleets that went in angered the Protoss, so they were wiped out. Rumors are getting more and more incredible, and the factions can't find a better reason to explain the vanished warships.

It's true that he angered the Protoss, but it wasn't an ancient civilization, but a real Protoss. When it comes to the Protoss, all forces are very sensitive, they are afraid and want to get closer.

Protoss technology, there is no force that is not blushing. The interstellar war of that year was also triggered because of the technology of the overlord forces.

Legend has it that the Ulantis civilization did not belong to this universe, saying that their ancestors came from other parallel universes.

It is understood that parallel universes, or multiverses, refer to a theory that has not yet been proven in physics.

According to this theory, there may well be other universes outside of our universe, and these universes are a reaction to the possible states of the universe, which may or may not have the same basic physical constants as we know them.

But by analyzing Ulantis' technology, the overlords, and some of the top civilizations, they found some clues.

Even though the physical constants of each universe are different, they all have one thing in common, that is, "energy", no matter what form of existence, belongs to the form of "energy".

Matter can be converted into energy, and energy can also be converted into matter. Even if the rules are different, this most basic condition still needs to be there.

The rules in the universe are only the form in which one substance is transformed into another, or the method, technology, etc.

The difference is the process of transformation and the corresponding conditions, and the same is the result. Of course, the "result" here does not refer to the transformation into the same substance, but to the fact that different methods eventually merge one or two substances into another or more, or decompose into more.

To put it simply, it's "conversion". The transformation of one substance into another requires the intervention of energy.

Queen Ulantis's best technology is that she has found the truth of energy. Crystals, Crystalstone Guards, Ties, and the Prosperity, they are the best proof of this.
