Although he felt very ironic, Chu Tianjiang had to admit that war was indeed a powerful force to promote scientific and technological progress.

"Thankfully, instead of being destroyed in this civil war, we made the greatest discovery of all time, and one that changed the entire civilization."

"Space Technique?"

"It's not one discovery, it's a lot of discoveries, but they're all related to space technology."

"This ......"

"At that time, the civil war was divided into two camps, namely the home star civilization and the Barrow star civilization, and the main contradiction that caused the civil war was the right to use energy."

"Energy?"

"Don't you think energy is an issue?"

"There's plenty of water on the home planet, and you can't possibly fail to master controlled nuclear fusion, right?"

Ivey was stunned for a moment, then laughed and said, "Do you think that the controlled nuclear fusion technique is very advanced?" More than a thousand years before the outbreak of the Civil War, that is, before our conquest of Barrow, we mastered the technology of controlled nuclear fusion, but it was definitely not the most advanced energy technology. ”

"This ......"

"What's more, we need far more energy than humans. You should be well aware that the more developed a civilization is in science and technology, the more energy is needed. It can even be said that the amount of energy required by a civilization can most intuitively reflect the scientific and technological level of this civilization. ”

Chu Tianjiang did not refute this, because human civilization is like this. For example, before the Great Geological Change, the average person in human civilization consumed more energy in a day than a country with tens of millions of people consumed in a year during the agricultural civilization.

"At the time of the advent of controlled nuclear fusion, we also believed that the water resources on the home planet would ensure that we would not have to worry about energy for tens of millions of years to come. Unfortunately, less than a thousand years later, we found that this energy source is nothing. After the end of the war against Barrow, energy became our most important, if not the only resource for survival. ”

"How is this possible?"

"How could it be?" Ivy looked at Chu Tianjiang and said, "The fact that you were able to come here shows that before that, you were very likely to be another form, a form different from material life. ”

"Energy Body Life."

"Then you should know that the energy body life needs energy."

"This ......"

"Of course, a true energy body life, if it does nothing, has an almost infinite life. But any intelligent life is alive, it is impossible to do nothing, it always has to engage in some work, it also needs entertainment, it needs spiritual enjoyment, it needs more things, and these activities will consume energy body, that is, consume life force, so energy body life needs enough energy body, and it needs enough energy. ”

"At that time, all of you were transformed into energy body lifeforms?"

"Of course, and it's an inevitable consequence."

"What do you mean?"

"This wormhole space is actually also a subspace, but a singular subspace composed of condensed mass bodies."

Chu Tianjiang was secretly surprised, because he understood what Ivey meant.

"We used the subspace technique to defeat the native civilization on the Barrow Star and conquered the entire Barrow Star, and the only one who can directly use the subspace technique is the energy people, at least according to our understanding at the time, only the energy people can enter the subspace and reach the destination through the subspace migration. It is precisely because of this that shortly after the end of the war against Barrow, we entered the era of quantification. At the time, this was still the main way we evolved ourselves, and we even gave up on genetic science, believing that energy could replace everything, give us eternal life, and give us unimaginable strength. ”

"Unfortunately, you're wrong."

"Yes, not only wrong, but outrageously wrong. Not only is the energy body life imperfect, but there are also many defects that cannot be repaired. ”

"For example......"

"The first thing we realize is the infinite demand for energy for energy in the life of the energy body, and if a huge multiplier is added to this infinite demand, it will be even more terrifying. To put it bluntly, any energy body life has an infinite demand for energy, and we have too many individuals. ”

"Energy is the problem?"

"At the time, energy wasn't the main issue."

"This ......"

"We've mastered the subspace technique, so we're able to get energy from a lot of places, and it seems to be an inexhaustible source of energy. At least until we find out that we are in a completely enclosed micro-universe, all individuals believe that energy is definitely not an issue. ”

"For what?"

"Because we're able to get energy directly from the stars."

"What!?" Chu Tianjiang was very surprised.

Actually, you shouldn't be surprised. Subspace technology allows us to go anywhere, and allows us to get energy from anywhere. ”

"That is, go directly into the interior of the star and then get the star's energy?"

"So to speak."

"But ......"

"That's crazy, isn't it?" Ivey smiled and said, "Of course, the application of this technique is also a process of gradual understanding. Like the solar system in which humans live, there are also some giant planets in our star system that are composed of gaseous or liquid hydrogen, and several giant planets are larger than Jupiter, and their masses have almost reached the critical point of becoming stars. What we started out with was to harness the energy from these giant planets. This is not only easier but also safer than getting energy directly from the stars. ”

"And then?"

"With these giant planets, in just a few hundred years, we have created an incomparably brilliant and incomparably large civilization."

"Huge?"

"Do you know how many individuals we have when we reach our peak?"

Chu Tianjiang shook his head, he didn't guess, he didn't imagine.

"Almost ten trillion."

"What!?"

"At that time, the entire home planet and Barrow were cities, and they were cities in the sky and in space. In order to protect the planet's ecosystem, we have built all the cities in the air, even in synchronous orbit. Of course, this also means that we need to pay a bigger price and consume more energy. Before the outbreak of the Civil War, there were as many as four trillion inhabitants on the home planet, and the same number of inhabitants on Barrow, and almost two trillion individuals living on other planets, and we have even begun to ecologically modify some solid planets to accommodate more individuals. In short, even if we enter the stage of self-evolution, there is no control over the number of individuals, because we all think that even if we use up all the resources of our own galaxy, we can go to other star systems to obtain resources. ”

"This ......"

"Of course, our star system is much larger than the solar system, so it's hard to imagine how big a civilization of a billion individuals really is."

Chu Tianjiang really couldn't imagine it, because as far as he could, the resources of the entire solar system could survive about a trillion human beings at most. And that includes the exploitation of Mars and other planets with water resources, including the moons of Jupiter and Saturn.

"In a sense, it was the sheer scale that sparked the civil war."

"Or despair for the future."

Ivey smiled reluctantly and said, "The understanding of cosmic space is a gradual process. This is true of human beings, and so are we. Although before the outbreak of the Civil War, some scientists proposed that the ubiquitous space barrier made it impossible for us to reach other star systems, so that we only had the resources of our own galaxy, and thus proposed that the number of individuals should be controlled by strict restrictions on fertility. However, these suggestions and warnings were not heeded, and even ridiculed, because all individuals believed that since we had mastered the spatial technique, it was only a matter of time before we broke through the spatial barrier, and it would not be too difficult. ”

"The opposite is true."

"It's not all."

"What else?"

"The full exploitation of energy, and the less equitable way of distributing energy."

"What do you mean?"

"At that time, I was nearing the end of my development of the giant planet. You've been to our star system and you should have noticed that, with the exception of two stars, the rest are solid-state planets. Although we know that the energy contained in the main star will not allow us to worry about energy problems at least in the short term, when we studied the main star, we found a problem that could not be solved at that time. ”

"What's the problem?"

"The huge mass of the main star has caused spatial distortion, which has limited our space technology, making it impossible for us to directly exploit the energy of the main star."

"This ......"

"Fortunately, there are two stars in our star system, and the secondary star is about the same as your sun, and the mass is much smaller than that of the primary star, so its spatial distortion does not have much impact on the space technology we have mastered, and we can develop the secondary star."

"A contradiction has arisen?"

"Exactly. The Barrow star is a sub-polar planet of the sub-star, and our parent star is the planet of the main star, so on the issue of developing the sub-star, the Barrow star civilization has a serious contradiction with the parent star civilization, especially in the distribution of energy, which is almost irreconcilable. ”

"This is the root of the civil war?"

"At that time, there was no more effective solution than war, and our culture determined that we had a very high degree of identification with war. The Barrow civilization is reluctant to share the energy of the inferior star with the home star civilization, and the home star civilization needs enough energy to survive, so war is inevitable. ”
