"Academician, we've been converting energy for a thousand years and haven't even used up a single star. You suddenly want 20? How long will it take us to accomplish that? And how many warships would we need to transport all these energy spheres?"
"General, we've calculated it. A star the size of the Sun can be converted into approximately 200 trillion pure energy spheres. The combined volume of these energy spheres is exactly the size of Earth. That means we need to input 20 Earth-sized spheres of pure energy into the Xuan Star Civilization's territory. Conversion itself isn't the problem; we can upgrade and improve the conversion equipment, it just takes a little more time. The real issue is how to get these energy spheres into the Xuan Star Civilization's territory. That's the real troublesome thing, but it's the only way we can get the vortex into the Xuan Star Civilization's territory."
"Forget it, Old Hu. Academician Zeng Academician Zeng have already tried their best. The Xuan Star Civilization is nothing. Let's just give up. We've already given up, so we don't care about giving up a second time."
"Alright then, you guys should continue trying to improve the conversion equipment. Anyway, the more energy balls the better. As for whether it will work or not, we'll see later. I'm fine. Xuan Star Civilization, if we can't eat it, we can't eat it. Just because we want to eat something doesn't mean we can."
Hu Yu left.
"The general hasn't really given up," Academician Zeng sighed.
"It's clear the general is under a lot of pressure."
"Of course it's huge. It's such a mess. We already got involved with the Fish Horse Star Civilization, and now the Xuan Star Civilization has come along. What's going on with those humans in the Mu Star Civilization's territory? What exactly does the Fish Horse Star Civilization want? Even I feel a sense of crisis, let alone the General."
On the third planet occupied by the Black and White Civilizations, two torrents, each hundreds of meters high, collided heavily on the sunlit side of the Planet Three after traveling for over a hundred hours. Towering waves surged thousands of meters into the air, and the enormous roar circled the Planet Three several times before slowly fading away.
A few days later, the giant waves slowly subsided, leaving only small waves tens of meters high still churning. It's estimated that they won't stop for at least a few months.
The surface of Planet Three has very little land left, with only a few scattered islands standing in the water. Planet Three has completely become a water sphere. However, Hu Yu is not worried. Stellar-Level Civilization are fully capable of surviving in water. They can either build underwater cities, construct floating islands, or even launch a new round of mountain-building using nuclear weapons. If they cannot even do this, there is no need for them to develop further.
By this time, countless people were already swimming in the waves. They salvaged useful materials, which were then carried away by the warships. Most people were simply playing in the water. They included people from both the Black Civilization and White Civilization. At first, Hu Yu wondered why everyone was such a good swimmer. Later, he realized that these guys were like rubber balls. Although they could suffocate in the water, as long as it wasn't a towering wave, it couldn't do anything to them.
"Your Excellencies, this planetary system is unstable; everything is in a fragile state of equilibrium. Any external factor could disrupt this equilibrium, and I don't need to elaborate on the consequences."
"Yes, sir, we have considered this, which is why we have been wholeheartedly developing technology all these years, hoping to leave this place before disaster strikes or to have the ability to cope with it."
"Yes, the water resources on Planet Three are now sufficient for your technological and population development."
"Human, I truly don't know how to thank you enough. With these abundant water resources, we can develop our technology without any worries."
"No need to thank me. Take care of yourselves. Now that the planetary terraforming is complete, it's time for me to leave."
"Sir, why are you in such a hurry? Why not stay a little longer so we can express our gratitude?"
"No need. I know what you're thinking. I don't intend to give you technology. Focusing on developing your own capabilities is perhaps the best path. However, I can give you a hint: energy. Your level should primarily research energy, as it is the foundation of everything. Also, I've had our biological scientists develop a gene-modifying drug for the Black Civilization. All the materials for the drug can be found in this planetary system. After the genetic modification, your color will become lighter, narrowing the gap with the White Civilization. Most importantly, you will no longer secrete this disgusting substance. You can wash yourself however you like from now on."
"Thank you, sir," said the white leader.
"Thank you, sir." The Black Sovereign said somewhat embarrassedly. After all, the matter stemmed from the bathing problem of their people. Due to their physical structure, their bodies secrete a liquid that, once solidified, can shield them from the intense radiation of Planet Two. However, this substance was extremely difficult for the White Civilization to accept.
"I hope to see you all again in this universe. Goodbye."
Having ended everything here, Hu Yu led the fleet to set sail again. Although Academician Zeng had found a way to create a spatial vortex, they had not found a way to send the energy ball into the territory of the Xuan Star Civilization. Returning to the vicinity of that spatial vortex would be of no use now. In addition, the crew members had not been home for a very long time. Hu Yu continued to sail towards JD4.
The Black and White Civilizations were just a minor incident. Good deeds are rewarded. A simple exploration helped resolve the conflict and water resource issues between the two primitive civilizations. The academicians also gained inspiration from it and found a way to create space vortexes. It was a meaningful good deed, Hu Yu thought.
Traveling at breakneck speed, the fleet finally returned to Earth Two. Hu Yu felt ashamed to face his family and friends. His original plan was to spectacularly destroy the Xuan Star Civilization, but in the end, a thousand years had passed with nothing to show for it, and so many crew members had been separated from their families. Thinking of this, Hu Yu felt deeply guilty. However, Hu Yu didn't show it. As the fleet leader, he couldn't appear dejected in front of the public; even without success, he had to maintain a positive demeanor.
As soon as the crew arrived at Earth Two, they all rushed to their respective homes, eager to return. Hu Yu understood perfectly. After briefly arranging their work, Hu Yu also headed towards his long-missed home.
Xiao Xiao knew when Hu Yu would return, but she didn't go to greet him or answer his communication requests. This gave Hu Yu a bad feeling, which grew stronger the closer he got to home. Finally, he stopped. It was already midnight, and there were hardly any people on the streets. Moreover, Earth Two was very safe, so Hu Yu didn't have any guards accompany him.
Crossing several streets, Hu Yu walked straight into a shop selling unusual items. Such shops were rare on Earth Two. They usually sold various natural crystals or strange objects collected during explorations of other planets. Although the fleet's technology could manufacture almost anything, humans always held nature in high esteem.
