Super Battleship Reborn

In the vast universe, a huge fleet is advancing rapidly, and their speed relative to Tianyuan Si has reached 3,000 kilometers per second. But since there is no obvious reference here, they appear to be stationary.

But by observing the redshift and blueshift, Xiao Yu determined that he was really moving, not standing still.

The light of the stars in front of Xiao Yu began to turn blue, while the light of Tianyuan Si behind Xiao Yu became a little red. This is the redshift and blueshift. Because Xiao Yu is sailing fast forward and approaching the star in front, the light of the star in front will turn blue. On the contrary, because Xiao Yu is moving away from the star behind, the light behind the star will turn red. .

In this vast void, Xiao Yu's fleet was a busy scene. Xiao Yu has produced countless robots with basic power structures, shuttled back and forth between large transport ships and large foundry ships, and transported a large amount of materials into the foundry ships. In the foundry ships, there are a greater number of robots busy. . They used these materials to process, manufacture, and assemble a series of methods to create spaceships, which were added to Xiao Yu's fleet.

The number of spaceships in Xiao Yu's fleet is increasing every moment.

Seventeen years have passed since the hydrogen bomb flash was observed. The total number of ships in Xiao Yu's fleet has grown to 110,000. More than 90 large transport ships have been emptied, and all the materials loaded on them have become ship by ship. Xiao Yu started the transformation of the transport ship.

Each of these transport ships will be able to transform into three county-level spaceships, so Xiao Yu naturally cannot waste these materials.

It has been twenty-one years since Xiao Yu left the Tianyuan Four Galaxy. In these 21 years, Xiao Yu has sailed a total of two trillion kilometers, which is almost one-fifth of a light-year.

In another three years... In another three years, if the Lucca fleet hasn't caught up, I'll be basically safe. Xiao Yu thought silently.

After reaching the Tiancang five star system, it is time to start the research and development of a new fusion engine. The current engine power and fuel utilization are not enough to support my spacecraft to reach the speed of five percent of the speed of light. This means, I have to develop a more efficient engine.

Although the Lucca civilization is a third-level civilization, their speed has not reached the speed of 5% of the speed of light. Xiao Yu specifically asked Luca No. 2 for this, and Luca No. 2 replied that they are only the third-level primary civilization, and they are the ones that have just stepped into the third-level civilization. They probably still need hundreds of years of development to be able to Increase the speed of the spacecraft to five percent of the speed of light.

And the most peak third-level civilization, its speed can even reach 50% of the speed of light, which is 150,000 kilometers per second. Fifty percent of the speed of light can be regarded as the limit of the regular navigation of the spacecraft. Only some special small spacecraft, or weapons and the like can exceed this speed.

To break through this limitation, we must find another way.

A fourth-level civilization is undoubtedly a civilization that has mastered a new energy source, because nuclear fusion energy is definitely not enough to support the huge energy demand of super-light travel. Well... a fourth-level civilization, it is very likely that the proton-neutron level is used. The decay of matter to obtain energy is more than ten times more efficient than nuclear fusion. And... within a thousand years, I am confident that the technology to obtain energy in this way will be researched! Within a thousand years, Upgrade to the fourth-level civilization! Xiao Yu thought with confidence.

Luca No. 2, today you come and tell me about the composition of civilization in the universe. The work in his hand came to an end, Xiao Yu was in a mood and summoned Luca No. 2.

Luca No. 2 replied respectfully: Master, what kind of information do you want to know?

Well... in the universe, no, in the Milky Way, how many different types of civilizations are there?

Within the Guardian Alliance,

Civilizations are roughly divided into these types. The first is scientific and technological civilization. Intelligent organisms evolve through the development of science and technology. The second type is alien beast civilization. Alien beast civilization achieves evolution by developing itself. Alien beast civilization above the third level has the ability to launch interstellar voyages with its own body. The third type is mechanical civilization, which is developed by the intelligent computers left behind after the demise of scientific and technological civilization. Mechanical civilization generally has an extremely large number of warships, wandering in the universe like locusts, but they generally do not have the ability to evolve. Ah, of course this is not about you, please don't misunderstand. Luca No. 2 said, suddenly panicked.

Nothing, you continue to talk. Xiao Yu said with some amusing.

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 nightmares of all civilizations, ghost races...

Ghost tribe? This was the second time Xiao Yu heard this term, and he couldn't help but be very interested.

Yes, ghosts. Ghosts are a special kind of existence. They have no entity, just a radio wave-like existence. They are bloodthirsty and powerful, and can evolve by devouring the souls of intelligent creatures. Evolve to high-level ghosts The clan is extremely terrifying, in the past 70 million years, the total number of recorded civilizations that have been exterminated by the ghost clan has reached more than 3,000, and there is even a fifth-level civilization.

Ghost race?! How is it so similar to Wood Spirit? Hearing Luca No. 2's explanation, Xiao Yu was smart, and suddenly remembered the Wood Spirit who was imprisoned by him.

Even now, there are some wood spirits on Xiao Yu's spaceship. However, since Xiao Yu obtained more advanced material casting technology, Xiao Yu has given up the practice of using wood spirits to strengthen materials. Those wood spirits were also put into the storage room by Xiao Yu, and they hadn't been asked for a long time.

Ghost race is the common enemy of scientific and technological civilization and alien beast civilization. Because mechanical civilization has no soul, ghost race disdains them. Every time ghost race is discovered, it will trigger large-scale encirclement and suppression in the entire galaxy. , 30 million years ago, in the face of an extremely powerful ghost clan, the Sweeper and Guardian civilization even had a precedent for joint confrontation. In this way, these two civilizations almost failed miserably, and finally the Sweeper civilization was dispatched. The Neutron Battle Star exterminated that ghost clan. Luca No. 2 explained in detail.

Xiao Yu thought silently.

I don't know if the wood spirit is a ghost family... If it is really a ghost family, then the fun will be great. I actually imprisoned such a powerful thing? This matter cannot be known to the Lucca people, I will study it myself. Xiao Yu made up his mind, and at the same time, he raised another question.

How did the ghost race come into being?

Luca No. 2 shook his head: I don't know. But there is a certain pattern to the appearance of ghost races. The place where they were first discovered is always in a place with civilization, but it has been extinct. The latest research shows that ghosts The formation of the clan may be related to the extinct civilization. Among about a thousand extinct civilizations, there will be a ghost clan once. For example, the ghost clan discovered this time was found around a yellow dwarf star. The third planet of the yellow dwarf once had a technological civilization.

Xiao Yu jumped in his heart and immediately asked, Yellow dwarf? Give me the specific parameters of this yellow dwarf.

Luca No. 2 did not dare to neglect, and immediately passed a piece of information 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 kilograms. The stellar spectrum is classified as a G-type main sequence star with an absolute magnitude of 4.83. , the surface temperature is 5778K, there are eight large planets, the third planet once had a second-level intermediate civilization, but this civilization was wiped out by the sweeper civilization...

This is the sun, the sun that nurtured my growth. Xiao Yu thought silently.

Xiao Yu manipulated the robot and took out the box where the wood spirit was stored. Through the camera, Xiao Yu watched it silently.

Could it be... that you are all the souls of my people who would not rest after their death? On Jupiter, I have destroyed so many wood spirits... I'm sorry, I really don't know.

At this moment, Xiao Yu had mixed feelings in his heart, not knowing what it was like.

Xiao Yu reluctantly calmed his mind, put this matter aside for the time being, and continued to ask: Apart from the ghost family, what other existences exist in the galaxy?

Lucca No. 2 replied respectfully: There are some unknown and terrifying existences. I have heard that hundreds of thousands of years ago, a powerful fleet of 100,000 spaceships of the Guardian Civilization was once in the first A cantilevered star suddenly disappeared around a certain star. The Guardian civilization sent a follow-up exploration fleet, but they also disappeared. I don't know the follow-up development, only know that the Guardian civilization will take the star's The sphere of influence is divided into extremely dangerous areas with a danger level of five. In the Milky Way, there are hundreds of dangerous areas of level four and above, and there may be unknown powerful creatures in these areas. .

Where is the nearest dangerous area to me? Xiao Yu asked.

Well...it's an open star cluster. In your civilization system, it's called the Pleiades star cluster. It's about 450 light-years away from you. The danger level is level 4, which is very dangerous. There used to be a level 5 civilization. The fleet, when passing there, all the creatures in the fleet died for unknown reasons, but the spaceship was not damaged. I don’t know the reason yet.” Luca No. 2 replied.

In the universe, it's really dangerous. Xiao Yu sighed, I want to continue to be strong, avenge human civilization, and let my clansmen rest in peace...
