Chapter 89: Unyielding Soul

In the vast universe, a huge fleet is advancing at a rapid speed, and they reach a speed of 3,000 kilometers per second relative to Tianyuan IV. But because there is no obvious reference here, they seem to be stationary.
But by observing the red shift and blue shift, Xiao Yu determined that he was really in motion, not static.
The stellar rays of light in front of Xiao Yu began to turn blue, while the rays of Tianyuan Four behind Xiao Yu became a little red. This is redshift and blueshift, because Xiao Yu is moving forward fast, approaching the star in front, so the light of the star in front will turn blue, in contrast, because Xiao Yu is far away from the star in the back, the star in the back will turn red .
Stinging in this vast void, Xiao Yu's fleet was a busy scene. Xiao Yu has produced countless robots with basic dynamic structures, shuttled between large transport ships and large casting ships, and transferred a large amount of materials into the casting ships. In the casting ships, more robots are busy. . They processed these materials through a series of methods, such as processing, manufacturing, and assembly, to create a spaceship to supplement Xiao Yu's fleet.
数量 The number of spaceships in Xiao Yu's fleet is increasing every moment.
Seventeen years have passed since the flash of the hydrogen bomb was observed. The total fleet of Xiao Yu's fleet has grown to 110,000, and more than 90 large transport ships have been emptied. All the materials loaded on it have become Ship to ship. Xiao Yu began the transformation of the transport ship.
These transport ships, each of which will be able to transform three county-level spacecraft, Xiao Yu naturally cannot waste these materials.
Xiao Xiaoyu has left Tianyuan four galaxies for 21 years. In these 21 years, Xiao Yu sailed a total distance of two trillion kilometers, almost a fifth of a light year.
"In another three years ... In another three years, if Luka's fleet has not chased it, I will be basically safe." Xiao Yu thought silently.
"After arriving at the Tiancang Five-Star System, it is time to start research and development of new fusion engines. The current engine power and fuel utilization are not enough to support my spacecraft to reach a speed of five percent light speed. This means, I have to develop more efficient engines. "
Although the Luka civilization is a third-level civilization, their speed does not reach the speed of five percent light. Xiao Yu specifically asked Luca II for this purpose. The answer from Luca II was that they were only third-level primary civilizations, and they had just entered the third-level civilization. They still need hundreds of years of development before they can Increase the speed of the spacecraft to the speed of five percent light.
And the highest level of the third-level civilization, its speed can even reach 50% of the speed of light, which is 150,000 kilometers per second. The speed of fifty percent light can be considered the limit of the spacecraft's conventional navigation. Only some special small spacecraft, or weapons and other things can exceed this speed.
If you want to overcome this limitation, you must find another way.
"Fourth-level civilizations are undoubtedly civilizations that have mastered new energy sources, because nuclear fusion energy is definitely not enough to support the huge energy requirements of super-light speed navigation. Well ... fourth-level civilizations are likely to pass the proton-neutron level This method of obtaining energy through material decay is more than ten times more efficient than nuclear fusion. And ... Within a thousand years, I am confident that I will be able to research the science and technology of obtaining energy through this method! Within a thousand years, Upgrade to a fourth-level civilization! "Xiao Yu thought with confidence.
"Luka II, today you come to tell me about the composition of civilization in the universe." The work in hand came to an end, Xiao Yu was in a mood, summoned Lucca II.
Luca II respectfully replied, "Master, I don't know what kind of information you want to know?"
嗯 "Well ... in the universe, no, in the galaxy, what are the different types of civilization?"
"In the Guardian Alliance, civilizations are roughly divided into these types. The first is scientific and technological civilization. Intelligent creatures evolve through the development of science and technology. The second is alien civilization, which evolves by developing itself. The third-level beast civilization has the ability to carry out interstellar navigation with its own body. The third is mechanical civilization, which was developed by the intelligent computer left by the demise of technological civilization. Mechanical civilization generally has an extremely large number of warships. It ’s like locusts wandering in the universe, but they generally do n’t have the ability to evolve. Ah, of course this is not talking about you, please do n’t get me wrong.
Luka II said with a sudden panic.
"Nothing, you continue to say." Xiao Yu said a little funny.
"The main types are these three, but there are some special existences in the galaxy. They are not civilizations, but they have certain characteristics of living things. For example, the nightmare of all civilizations, ghosts ..."
"Ghost race?" This was the second time Xiao Yu heard the term, and couldn't help but be very interested.
"Yes, the Ghost Tribe. The Ghost Tribe is a special existence. They have no entity, but a period of existence similar to radio waves. They are bloodthirsty and powerful, and can evolve by devouring the souls of intelligent creatures. Evolved to higher-order ghost The tribe is extremely horrible. In the past 70 million years, the total number of recorded civilizations destroyed by the ghost family has reached more than 3,000, and there is even a fifth-level civilization. "
"Wraith ?! How is it similar to Mu Ling?" After hearing Luka II's explanation, Xiao Yu was clever and suddenly remembered Mu Ling who was imprisoned by himself.
现在 Even now, there are still some wooden spirits on Xiao Yu's spacecraft. However, since Xiao Yu gained more advanced material casting technology, Xiao Yu has given up the use of Mu Ling to strengthen the material. Those wooden spirits were also put into the storeroom by Xiao Yu, and it hasn't been asked for a long time.
"The ghost tribe is a common enemy of scientific and technological civilization and alien beast civilization. Because the mechanical civilization has no soul, the ghost tribe dismisses them. Every time a trace of the ghost tribe is found, it will trigger a large-scale encirclement in the galaxy. 30 million years ago, in the face of an unusually powerful ghost family, the cleaner and guardian civilizations even had a precedent to fight together. In this way, these two civilizations were almost defeated, and finally the cleaner civilization was dispatched. The neutron battle star annihilated that ghost group. "Luca II explained in detail.
Xiao Xiaoyu thought silently.
"I don't know if Muling is a ghost group ... If it is a ghost group, then the fun will be great. I actually imprisoned such a powerful thing? This thing can't let the Lucasians know, let me study it slowly. Xiao Yu made up his mind, and at the same time raised another question.
"How did the Ghost Tribe come about?"
Luca II shook his head: "I don't know. But there is a certain pattern in the appearance of the ghosts. The place where they were first discovered is always in a place that has civilization but is extinct. Recent research shows that ghosts The formation of the clan may be related to the extinct civilization. About one thousand extinct civilizations will have a ghost group. For example, the ghost group discovered this time was found around a yellow dwarf. The third planet of that yellow dwarf once had a technological civilization. "
Xiao Xiaoyu jumped in his heart and immediately asked: "Yellow dwarf? Give me the specific parameters of this yellow dwarf."
Luca II did not dare to neglect and immediately passed a message to Xiao Yu.
Xiao Yu saw that this yellow dwarf star is located in the third cantilever of the Milky Way, with a diameter of 1.39 million kilometers and a mass of 2X10 ^ 30 kg. The star spectrum is classified as a G-type main sequence star with an absolute magnitude of 4.83 , The surface temperature is 5778K, has eight large planets, the third planet once had a secondary intermediate civilization, but the civilization was extinct by the sweeper civilization ...
"This is the sun, the sun that nurtured me." Xiao Yu thought silently.
Xiao Xiaoyu controlled the robot and took out the box containing Muling. Through the camera, Xiao Yu watched it silently.
"Don't ... you are all my souls who don't want to rest after my people die? On Jupiter, I have destroyed so many spirits ... I'm sorry ~ EbookFREE.me ~ I really don't know."
At this moment, Xiao Yu has mixed feelings in her heart, not knowing what it is like.
Xiao Yu reluctantly calmed his mind, put this matter behind his head for a while, but continued to ask: "Apart from the ghost race, what else exists in the galaxy?"
Luca II reverently replied: "There are still some unknown terrible existences. I have heard that hundreds of thousands of years ago, a powerful fleet of 100,000 spacecraft from the Guardian Civilization was once in the first A cantilevered star suddenly disappeared around it. The Guardian Civilization sent another follow-up exploration fleet, but it also disappeared. I do n’t know the follow-up development. I only know that the Guardian Civilization changed the star ’s The sphere of influence is divided into extremely dangerous areas with a danger level of 5. In the galaxy, there are hundreds of dangerous areas at levels 4 and above. In these areas, there may be unknown powerful creatures. . "
"Where is the nearest dangerous area to me?" Xiao Yu asked.
"Eh ... is an open star cluster. In your civilization system, it is called the Pleiades star cluster. It is about 450 light-years away from you. The degree of danger is level 4 and severe danger. There was once a level 5 civilization. Fleet ’s fleet, when passing by, all the creatures in the fleet died for unknown reasons, but the spacecraft was intact. I do n’t know why.
Luca II replied.
"In the universe, it is really dangerous." Xiao Yu sighed. "I want to continue to be strong, avenge human civilization, and let my people rest in peace ..."
