Evolution is inherently a change, a change that is moving in a more powerful direction.

Like any change, evolution requires momentum, whether from the environment or elsewhere, and there must be enough momentum to drive evolution.

"This war lasted almost a thousand years."

"A thousand years?" Chu Tianjiang was very incomprehensible. According to Ivey at the beginning, the civilization on that astral body was not developed, at least not compared to the invaders.

"You've been to our micro-universe and know how big our galaxy is. For us at the time, distance was a huge obstacle that was almost impossible to overcome. ”

Chu Tianjiang was stunned for a moment, and then understood.

The microcosm in which the invaders are located is indeed much larger than that of humans, with a radius of almost a hundred times that of the solar system, and the distance between the primary star and the secondary star is more than a light-year. For a civilization that has just entered the age of the universe, this is indeed an extremely long distance.

"In fact, long before the industrial age, our astronomers discovered a second-class star and concluded how it behaved. In ancient times, our ancestors even created a lot of beautiful, bleak myths about this star. It wasn't until we mastered enough advanced science and technology that we realized that this star was different from the other stars in the night sky. It is for this reason that we realize that our parent star is in an extremely large galaxy, and that there are two stars in this star, and in addition to the extremely large primary star, there is also a sub-star, and this sub-star can also provide light and heat for life. ”

"And then?"

"The observation of sub-stars has led us to discover extraterrestrial civilizations. Of course, this is what you often say. The more important discovery is that this civilization has at least entered the industrial age, mastered electricity, and even learned how to use electromagnetic waves, because they are emitting electromagnetic waves into space. ”

"What?"

"Of course, it's just a good wish, and they are also looking for other civilizations, and they think that other civilizations will get along with them."

"This ......"

"Unfortunately, instead of friendly neighbors, they found utter destruction. Doesn't that sound familiar? ”

Chu Tianjiang was a little speechless, because humans had done similar stupid things. Fortunately, in the solar system where humans live, only life exists on Earth. If human beings were born in such a complex star system, and an intelligent civilization appeared on a nearby planet, then human stupidity would only lead to death. It is important to know that there can be no peace between two completely different intelligent civilizations.

"It's just that the long distance makes it difficult for us to give full play to our technological advantages."

"For what?"

"It takes enough time to cross long distances, and any civilization is constantly growing, and time can bring everything."

"This ......"

"The first conquest of this inferior planet, named 'Barrow', ended in complete failure. It took us a full hundred and fifty years for the first starfleet we sent to reach Barrow, and by the time we arrived, the civilizations on Barrow had mastered more advanced science and technology. As a result, instead of destroying the intelligent civilizations on Barrow, our starfleet has been wiped out, and the enemy has been made to realize that their neighbors are not friendly and that they must fight for survival. ”

"And then?"

"Fortunately, by the time all this happened, we had mastered more advanced science and technology, including the technique of breaking through the speed limit."

"Space Technique?"

"To be exact, it's just a subspace technique."

"What do you mean?"

"This is a later name, because at that time we didn't know that the star system we were in was actually a completely closed micro-universe. A true space technique must have the ability to break through the space barriers between the micro-universes, and the space jump within the micro-universe is only a sub-space technique. Of course, this is enough. With the subspace technique, the long distance between the two stars is no longer an obstacle. ”

"Okay, what's next?"

"We are one step ahead of the enemy, although it is only one step, but it is enough to decide the victory or defeat of the war. Before the intelligent civilization on Barrow developed the subspace technique, we launched a decisive attack that fundamentally eliminated the threat of the enemy. ”

"Won?"

"A decisive victory was achieved, but the war did not end there. The war continued for the next eight hundred years. ”

"This ......"

"Confused, right? Now that we have won a decisive victory, the war should be over. Ivey paused for a moment and said, "Attacking Barrow is not only to eliminate the threat around us, but also to solve our internal conflicts. As mentioned earlier, there is an agreement between the two major populations within us, and Barrow belongs to the Genetic Warriors, so we can't destroy Barrow, or even destroy it on a large scale. As a result, we spent more than enough time dealing with the remnants of the enemy. ”

"Hundreds of years?"

"It's long, but it's valuable."

"What is it worth?"

"In addition to getting the Barrow Star, there is an even more significant gain. That is, other intelligent beings can help us in our evolution. ”

At this time, Chu Tianjiang suddenly understood.

"Obviously, you've thought of it. Integrating the superior genes of other intelligent life forms can make us stronger and smarter. Because there have been two wars with other intelligent civilizations, it is no longer a difficult thing for us to accept the genes of an alien race. More importantly, the fact that we were able to win these two wars and establish our world on another astral body is inextricably linked to this fusion at the genetic level. You must know that the environment on Barrow is not suitable for us, at least it cannot allow us to survive directly, so we must obtain the ability to survive on Barrow through gene fusion. ”

"From this, you entered the stage of self-evolution?"

"You can say that, but this is just the beginning, or a useful attempt. In any case, within any civilization, there will always be people who cling to old ideas, refuse to change for the new environment, and think that the past is always good. ”

"This ......"

"Thankfully, after the war against Barrow, this group was in the minority, and the vast majority of our individuals accepted the benefits of genetic modification and accepted the change. It was in this way that we did not have a civil war, but a small upheaval. ”

"Turmoil?"

"It's not wrong to say it's an internal ****. All in all, after this upheaval has been suppressed, we no longer resist genetic modification, and we no longer reject the theory of self-evolution. ”

"Then, you set your sights on the world beyond the micro-universe?"

"Entering the stage of self-evolution is going on at the same time as exploring a broader living space, and it is at this stage that we also discover that the star system we live in is a completely closed space, and even if we master the subspace technique, we cannot break through the space barrier. In a sense, the obstacles encountered in the exploration of the outer world also promote the development of self-evolution. To put it simply, before we find the technique to break the barrier of space, the space and resources we have are very limited, but as an intelligent creature born of natural evolution, we have an infinite impulse to reproduce. If the number of individuals is not controlled, it will not be long before we will run out of resources and perish in this completely enclosed space. The most effective way to control the number of individuals is self-evolution, through which each individual assumes a unique social responsibility. Although this deprives all individuals of the right to reproduce, it essentially guarantees the prosperity of the population. ”

"So, when did you master the space technique?"

"By human standards, it's almost 10,000 years ago."

"More than 10,000 years ago?" Chu Tianjiang was very surprised. In other words, when the invaders mastered the space technique, the great civilization issued a warning.

"What, surprised?"

Chu Tianjiang didn't say anything, he knew that there was no need to tell Ivey about some things.

"Actually, it was a very painful thing for us because we waited for a long time."

"How long?"

"About three thousand years."

"This ......"

"Soon after we captured Barrow, we discovered that we had mastered the subspace technique that prevented us from breaking through the edge of the galaxy. Since then, our scientists have been working on real space technology, but the long-term peace has made us lose the momentum to move forward. It wasn't until one day, when we discovered that the number of individuals we had grown to the point that the existing resources were too large to sustain us, that we realized the importance of developing science and technology, especially space technology, and we paid a very heavy price for this discovery. ”

"Civil war?"

Ivey nodded and said, "Although self-evolution has allowed us to establish a more stable social system, in the face of infinite demand, limited resources will inevitably lead to contention and turn into war. If it is not possible to open up a wider living space, war is also the only way to keep the race alive. To put it bluntly, only war can reduce the number of individuals and reduce the demand for resources. ”

"This ......"

"This is a civil war of great proportions, but it is also our last civil war."
