Just like Xiao Yu said, the conditions necessary for the promotion of a fifth-level civilization to a sixth-level civilization determine that this process cannot be peaceful, and in this process, it will inevitably be accompanied by war and killing.

Xiao Yu even began to wonder if there was an existence in this universe that deliberately formulated such a rule, the purpose of which was to make it impossible for civilizations to live in peace with each other, but to fight each other. The selfishness of a civilization determines that a civilization is unwilling to let other civilizations increase its strength, and the expansiveness of civilization determines that this civilization will do whatever it takes to increase its strength. This is an insoluble contradiction.

For Xiao Yu, it means that Xiao Yu wants to upgrade himself to the sixth level civilization, so Xiao Yu will try to obtain the unique technology of the other civilizations, and at the same time, Xiao Yu is unwilling to let the rest of the civilizations be promoted to the sixth level, so he will keep his unique technology secret. In other words, Xiao Yu is only willing to take, but not to give.

When every fifth-level civilization is only willing to take and is not willing to give, there is really no other way to solve the problem except war.

"The road ahead of our Shenzhou civilization must be paved with the flesh and blood of the rest of the civilizations. Only when enough civilizations have been killed and the paved road is long enough can we step on this path and enter the category of sixth-level civilization. In the process, we may succeed or fail and become a stepping stone for the rest of civilization. This is a journey full of blood and fire, everyone, be mentally prepared in advance. Lukka II said faintly, and there was a strange desolation in his voice.

There was silence in the room. Everyone is thinking about this.

"We have the Orb of Death, we have primary space weapons, we have four maintenance shields, and even in the not-too-distant future. We will also have a continent-class spaceship made entirely of fourth-level alien beast flesh and blood, through the analysis of the Murlian civilization technology tree, and by analyzing the development of applied science and technology brought about by the Guardian civilization ship, our new ship can have a speed of thirty-five times the speed of light, and we also have a computing module that is twenty times more efficient than the current one, in the fifth-level civilization, we are invincible, I don't think our civilization will fail. Luca III said.

"I believe that every fifth-level civilization thinks like this, and every fifth-level civilization will not think that it will fail." Lukka II said faintly, "Don't underestimate any fifth-level civilization. Any civilization that has been passed down for tens of thousands of years. All have a deep heritage. ”

"This scene reminds me of an old legend, in primitive times, when we were still confined to the surface of the planet, in the wilderness. There is a legend of raising Gu, and people will put dozens and hundreds of poisonous insects together. Let them kill each other. In the end, only one poisonous insect survived. Our situation is very similar to that of these Gu worms. Among the dozens or hundreds of fifth-level civilizations, only one fifth-level civilization can successfully reach the category of sixth-level civilization. Xiao Yu sighed and said, "But I don't think this fact can't be changed." ”

"Oh? Master, do you have any other ways to achieve your goal? Luca II asked.

"Rather than war and killing, I prefer to trade peacefully to acquire the unique technologies of the rest of the civilizations. We don't exist in the same way as the Merlian civilization. Our society as a whole is made up of spaceships, not planets, and our people are better suited to survive on spaceships than on planets. We have great mobility. We can easily take all our supplies with us, wander around the universe, and communicate with other civilizations. Xiao Yu said, "The trading market with a fixed location is easy to be attacked and lose all your money, but we are different. We carry all our military liliang with us, and I don't believe that any level 5 civilization can pose a threat to us. ”

"War has always served political purposes, and as long as political goals can be achieved, I don't care if war happens. So be it, in the course of future contact with the rest of the civilizations, war will only be used as a means of backup, and will be used only if peaceful means fail. ”

"The galaxy is empty enough, even if we can be the victors of Zuihou and let this galaxy be completely silent, it may not be a good thing for us. I even have a guess that I don't know if the disappearance of the seventh-level civilization has anything to do with the fact that the sixth-level civilization is too rare......" Xiao Yu sighed and said, "But no matter what, improving one's own strength is the most important thing, even if it is a peaceful transaction, it must be backed by one's own strong strength." That's it, these ships that continue to analyze the Guardian civilization will not be able to make breakthroughs at the level of basic science, and it is good to have some gains at the level of applied technology. ”

"In another three hundred years, we will sail out of curvature, and then, I will look for an inconspicuous star system to use as our base for development......"

With all these things in place and setting the tone for the future, the meeting ended and the scientists were once again busy.

A long period of 300 years has been spent in this busy day after day. During this period, there has been considerable development at the level of applied science and technology, while at the level of basic science, Xiao Yu has still made no progress.

In the past three hundred years, as usual, the fleet of the Guardian Civilization has not chased after it again, and the Taihao Civilization has not appeared. This reality made Xiao Yu probably relieved.

In the course of these three hundred years, the terrifying reproductive power of intelligent beings has been revealed. Up to now, the number of intelligent creatures under Xiao Yu's command has doubled, and now there are as many as 80 billion, which is enough to occupy 90 spaceships of the Homeland. If he continued to sail for another one or two hundred years, Xiao Yu's fleet would not be able to fit so many intelligent creatures.

However, Xiao Yu was not worried about this. The huge base of intelligent organisms represents more and more scientists who can contribute to the development of the Shenzhou civilization. After 300 years of development, the number of scientists in the Central Academy of Sciences has reached as many as 200,000, and it is still increasing rapidly.

In fact, 200,000 scientists are a small percentage of the 80 billion people out there. Even in the age of the earth, among the seven billion human beings, there are more than a few scientists. It's just that because of racial integration, frequent crises and other things, the explosive growth of the number of scientists has been suppressed, and now that there is no incident, the growth of the number of scientists has naturally exploded.

"The next step is to build a continent-level homeland spaceship, don't worry, the more intelligent creatures, the better, I don't have too many to come......" In this mentality, when the population just exceeded 80 billion, Xiao Yu also held a special celebration, and at the celebration, he also specially rewarded a couple who gave birth to ten twins.

In contrast to the vigorous development of the number of intelligent creatures, Xiao Yu's depleting material reserves. After experiencing the war with the Molian civilization, Xiao Yu encountered the pursuit of the Guardian civilization again, and now he has experienced a long voyage of five hundred years, in this span of nearly a thousand years, Xiao Yu basically has no chance to stop and recuperate, and all he consumes now is the materials that were previously reserved.

But it doesn't matter, now, in either way, it's time to stop and catch your breath. As long as he finds a random star system, Xiao Yu will be replenished with endless supplies. The decay engine can convert any matter into energy, and the universe is the most lacking in matter.

Xiao Yu controlled the huge fleet, broke away from the curvature of the voyage, and was quietly suspended in the void. The energy from the collision of the neutron star and the white dwarf star was still strong even if it crossed the distance of five hundred light years, but it could no longer have a large enough impact on Xiao Yu's fleet. Glancing at the still bright point of light behind him, Xiao Yu took his mind back.

Here, it is about 23,000 light-years away from the silver heart. The density of stars here is not low, and in Xiao Yu's visible vision, there are countless stars. The closest star to Xiao Yu is a subgiant that emits white light, but unfortunately, there are no planets around it.

So Xiao Yu ruled out this goal. Xiao Yu's gaze continued to search in the void, looking for them one by one, and eliminating them one by one.

"This star is about fifteen light-years away, it is a juvenile star, about 1.7 times the mass of the Sun, and there are two planets around it, one gaseous and one solid. There are dozens of moons around the gas giant, and in addition to that, it also has two rock chip belts, which is good, very good, and this star system is very suitable for our Shenzhou civilization to settle down. ”

"Let's move forward, then, in this star system, to complete another era of our great development. This star system will become a refueling station for our Shenzhou civilization, and after completing the replenishment here, we will embark on the road of searching for the fifth-level civilization in the galaxy. What awaits us ahead may be a tragic war, it may be a strange conspiracy, but before we face all this, let us take a good rest. ”

"The duration of this residency is tentatively set for two hundred years, and after two hundred years, leave here."

Under Xiao Yu's manipulation, the huge fleet once again entered the curvature voyage. Only this time, Xiao Yu's speed reached about thirteen times the speed of light. At this speed, in a year and two months, Xiao Yu will reach his goal. (To be continued......)
