Super Battleship Reborn

Chapter 31 The Tomb of Seven Billion Humans This is the last time away from the sun, and this time away, there will be no return.

As the distance got farther and farther, the sun became more and more dim, and Xiao Yu's mood became a little heavy for no reason.

The road ahead is long, and what awaits Xiao Yu will be a long journey of 10.5 light-years, and a long time of 6,300 years.

What strange things will you encounter on your journey? What kind of danger will be encountered? Xiao Yu didn't know. But Xiao Yu still decided to leave. What dominates a scientist's thinking is the crazy desire to explore, so crazy that even his life can be sacrificed.

Therefore, Xiao Yu did not choose to continue to develop in the solar system, but chose to set off immediately after gaining the ability to travel between stars.

In fact, to be precise, Xiao Yu's current technology can only be said to have acquired the ability to travel between planets. Because at the speed of nuclear fusion power, interstellar navigation takes thousands of years, which is enough to shut out all creatures with a lifespan of less than 10,000 years. However, after Xiao Yu combined with the computer, he abandoned his physical body, leaving only his spirit, and his lifespan can be said to be almost endless. Relying on this almost cheating method, he obtained the ability to use the technology of interplanetary navigation to carry out interstellar navigation.

Humans have calculated that the minimum threshold for interstellar navigation is to reach five percent of the speed of light, which is 15,000 kilometers per second. In this case, it will take about two hundred years to reach the Tianyuan four galaxies from the solar system. Compared with the lifespan of humans at that time, this time is already within an acceptable range.

However, before the development of a new generation of engines, the speed of 15,000 kilometers per second was a bit extravagant for Xiao Yu.

Once again, returning from Jupiter to Titan, Xiao Yu did not land. On Titan, two large photonic computers have been transplanted by Xiao Yu to the Sun and Yuanhang respectively. The current base is completely controlled by the computer on the small spacecraft at the beginning.

Although it seems to Xiao Yu now that this computer is really outdated and its computing speed is too slow, but now on Titan, ninety-nine bases have stopped running, and all kinds of machinery have been sealed. , there are only some simple maintenance tasks left, which is enough for this computer to do.

Titan's atmosphere has extremely low oxygen content and low temperature, so there is no need to worry about mechanical rust and damage. Xiao Yu hopes that these machines and equipment can exist for a long time, and after tens of thousands of years, they are still intact.

Because a large part of the atmosphere of Venus has been stripped away, resulting in a decrease in the temperature of the surface of Venus, in the infinite future, it is very likely that intelligent creatures will evolve on Venus. So Xiao Yu hopes that these things he left behind can point out a little evolutionary direction for the intelligent creatures on Venus, and by the way, also in the solar system, leave some evidence that humans once existed.

Looking at Titan shrouded in mist in space, Xiao Yu was filled with emotion.

Twenty years, just like that. Xiao Yu thought silently in his heart.

In the blink of an eye, it has been twenty years since he left the earth.

In the past 20 years, a lot of things have happened. On the earth, the time of living carefree and carefree seems to be just yesterday.

Scenes from the past flowed through Xiao Yu's mind.

The first time away from the earth, the fear of the collision between the moon and the moon, the surprise of the first meal, the difficulty of walking on Titan, the excitement of mastering the controllable nuclear fusion technology, and so on, etc., Piece by piece, piece by piece.

Let's go, let's go. In the solar system, although it is safe and comfortable, how can it be possible to achieve great achievements without experiencing wind and rain. Let's go, let's go, the boundless universe is the ultimate goal of my exploration.

Xiao Yu threw thousands of thoughts out of his mind and controlled the huge fleet to fly towards Saturn.

In the Saturn system,

Xiao Yu will refuel for the last time, and then, Xiao Yu will leave the solar system and start a long voyage towards Tianyuan Si.

Xiao Yu frantically replenished fuel and stayed in Saturn's atmosphere for half a month. He didn't leave Saturn until he couldn't hold it any more.

After taking a reluctant glance at Titan at the end, Xiao Yu moved forward resolutely and galloped away from the solar system.

At this time, Xiao Yu had already filled half of the entire fleet's spaceships, including three county-level spaceships, Yuanhang, Sun, and Tianyuan, as well as nearly 500 village- and township-level spaceships. kinds of materials. If it wasn't to deal with possible unexpected situations, if it was necessary to maintain mobility for some of the spaceships, Xiao Yu even planned to load all the spaceships with supplies.

During this period of time, Xiao Yu has deeply realized a truth. In cosmic space, the place where meteorites fly around is not the most dangerous place, but the most dangerous place is the empty place. Because there, any star has a distance of at least thousands of years, and there is nothing there. If there is an accident, you can't get any supplies to replenish, you can only wait for the energy to run out, and then die and become cold of cosmic stones, drifting with the tide in infinite time.

This is only a galaxy-level voyage, and if it is a river-level voyage, it will be even more terrifying. There, to get a piece of scrap iron, you might need to travel at the speed of light for millions of years.

Long time is the biggest enemy of interstellar navigation.

Xiao Yu was full of thoughts, while thinking about things at random, while manipulating the fleet to speed up slowly. At the beginning, when he left the earth, Xiao Yu was very eager to leave the solar system, but when he really wanted to leave the solar system, Xiao Yu was reluctant to part.

Xiao Yu thought of a person. It was a girl, very young, very beautiful, full of energy, pure and lovely. When it was still on Earth, this girl was a researcher at Xiao Yu's research institute.

That girl liked Xiao Yu, but Xiao Yu put all his mind on science, disdain for the relationship between men and women, and even severely criticized the girl because of this matter, causing the girl to leave Xiao Yu's research sadly Place.

Xiao Yu never thought that he had done anything wrong, but at this time, Xiao Yu felt a little regret in his heart.

She is... dead now, right? Along with seven billion human beings, she entered death together. But it seems that since she left the institute and then until the destruction of the earth, during this period, a total of seven years, I have not gotten her. I don't know what happened to her later.

Xiao Yu thought, manipulating the three-dimensional color projector of the Sun, and weaving a figure out.

In the cabin of the Sun, with the movement of the three-dimensional color projector, the figure of a girl gradually appeared.

Well, no, her eyes should be bigger. Uh, well, her waist should be thinner, the bridge of her nose should be higher, her chest should be bigger...

Xiao Yu modified various data, and gradually, the three-dimensional color projector projected the figure of a smiling girl in the air.

She stood there like that, her eyes full of tenderness looking ahead, as if she had a lot to say.

Xiao Yu generated a piece of code, and after executing it, the girl made a sound.

Director Xiao, are you okay?

The voice was soft, shy, and the same tone of voice she had spoken on Earth.

Xiao Yu stared blankly at her figure and murmured, Chen Mo, I'm fine, I'm still alive, how about you?

I'm already dead. I died twenty years ago. The girl said with a slight smile.

Yeah, you are already dead, you died twenty years ago, and I have gained infinite life. But I have no body. Xiao Yu said sadly.

It is a very risky act to separate the body and mind. When he was on Earth, Xiao Yu happened to get an unknown substance from the universe. After several years of concentrated research, he risked great danger to strip his spirit from his body. Before fully grasping all the properties of this substance, Xiao Yu would never dare to take risks.

That is to say, even if there is another body, Xiao Yu will not choose to combine it. Because of the combination, Xiao Yu will not be able to come out. Xiao Yu will be restricted by his body again, and he will grow old and die.

Chen Mo, wait for me, when I completely master the genetic code of human beings, I will resurrect you. Xiao Yu murmured.

When he left from above the earth, Xiao Yu had stored the human gene bank and sperm bank, but when he was avoiding the collision of the wooden moon, he was hit by a meteor and lost all of them.

I'll wait for you. Chen Mo smiled slightly. After saying this, Chen Mo's body instantly turned into a light and shadow and disappeared.

When you are resurrected, I will accept your confession. Xiao Yu whispered, staring blankly at the light and shadow that Chen Mo's body turned into.

Huh... Taking his mind back from his infinite thoughts, Xiao Yu sighed lightly, put aside these messy thoughts, and continued to control the huge fleet to escape outside the solar system.

Gradually, the months passed in a flash.

Xiao Yu's fleet has reached the orbit of Uranus.

It's almost reaching the orbit of Uranus. Here, leave a tombstone of human civilization. Xiao Yu thought.

Uranus orbits about 2.7 billion kilometers from Earth's orbit. Looking at the sun in the orbit of Uranus, it is just a bright spot in the sky, and there is no essential difference between it and the rest of the stars.

Xiao Yu sighed and used the metal material he had reserved to create a tombstone, and then used nuclear fusion technology to create a battery—a battery that could last for at least millions of years to supply energy to an ever-bright lamp.

This tombstone will revolve around the sun in a cycle of one hundred and thirty years, and within one million years, this ever-bright lamp will remain on, illuminating the line of words engraved on the tombstone.

One of the humans, Xiao Yuli!
