Lu Na is the last person of the Xianlong civilization.

The Immortal Dragon Civilization is the most powerful civilization in this universe, a ninth-level civilization.

However, the universe is so small that its life cycle from the Big Bang to death is only 20 billion years.

The Immortal Dragon civilization was born on a planet in a galaxy 5 billion years after the Big Bang.

It took 3 billion years to evolve a smart civilization, 1 million years to go out of the planet, 30 million years to conquer a river system, and 1 billion years to become an eighth-level civilization.

In the next 3 billion years, the Xianlong civilization fought in the east and west, and in the north and south, in an ultimate battle, it eliminated the last strong opponent, fused its civilization core, and was promoted to a ninth-level civilization.

It was the most glorious era of the Xianlong civilization, and the entire universe obeyed the orders of this civilization and bowed down to it.

But since the universe began to shrink at an accelerated pace, the good days of the fairy dragon civilization have come to an end.

Black holes, endless black holes, are destroying this universe.

At the beginning, there was still a lot of time, and the Xianlong civilization was unhurried, thinking that within 5 billion years, the Xianlong civilization would definitely be able to find a way to deal with the collapse of the universe.

"Space is infinite, even if all matter converges into one point, as long as we flee far enough, even if the universe is destroyed, the fairy dragon civilization will still be able to get a new life in the next big bang."

But three billion years later, scientists have made a shocking discovery.

"Not only is matter collapsing, but even space is collapsing!"

"When the day of the end of the universe comes, there will be no surviving space, and nothing can escape the singularity that wants to bring all matter and energy together."

"We're dead."

The scientists panicked, and so did the upper echelons of the Immortal Dragon civilization.

They're trying to figure out how to solve this problem.

It's just that the Immortal Dragon Civilization has mastered all the laws of this universe thoroughly, and even mastered the technology of making stars and using them as starship energy sources, but there is still one technology that has not broken through.

Space technology.

In fact, the space technology of the Xianlong civilization is not weak, space storage devices, wormholes. can be manufactured.

Even using space technology, they have made a machine that can turn back time and go back 10 years.

But this has no effect, and each time the time machine is used, it consumes a lot of energy, and it does not change the history of their demise.

"Unless we are promoted to a tenth-level civilization and have the ability to break the barriers of the universe, we can escape to other parallel universes through guò to avoid our demise."

"That's just too hard, the energy to break the barriers of the universe. It has to be more than 100 billion carga...... Such a huge amount of energy can only be produced in supermassive black holes. ”

"But the Immortal Dragon Civilization still can't control the black hole, and that's something that only a tenth-level civilization can do."

……

In the last billion years, seeing more and more black holes in the universe and smaller and smaller spaces, the Xianlong civilization has thought of countless ways, but there is no way to avoid going to the end.

Until the last star was swallowed up by a black hole, the entire universe was darkened.

There was chaos, even as all civilizations stopped fighting. United, but what's the point? The most powerful immortal dragon civilization has no choice, and no matter how much other civilizations toss, it will not help.

War resumed, and desperate civilizations fought against each other.

Anaphase. The remaining civilizations, not even the madness of cannibalism, have driven their warships into a bottomless black hole in order to end the pain of waiting for death......

At last. In the vast universe, there is only one civilization left.

Immortal Dragon Civilization.

……

Lu Na, the princess of the fairy dragon civilization. He is 19988 years old.

She had long, silver-white hair, a long dress that radiated the light of colorful stars, and a pair of white high-heeled boots.

Coupled with her delicate white and tender goose egg face, combed very neat hairstyle with bangs, she is graceful and outstanding, and has a very charming temperament......

She is the most beautiful princess of the empire.

Everyone loved her.

But since Lu Na was born, except for the occasional time when people laugh at some heavy festivals, the rest of the time is sad.

Even, there are people who kill themselves every day.

In order to prevent the scientists from walking again in despering remarks, the emperor even had the soldiers kill all the scientists and stop a qiē scientific research and education activity.

Not only that, in order to avoid suffering, more than 90% of the people in the empire chose to cleanse the memories in their brains, enter the virtual world, and live an ordinary life.

Because it's a soul-bound game, once you die in the game, you will die in reality.

After the birth of that game, only 5,000 years have passed, and the population of the Xianlong civilization has decreased from 100 billion to 100,000.

And for a complete family, as long as one person chooses to enter the game, after spending a lifetime, others will also follow in the footsteps.

Before entering the game, Lu Na's queen mother stroked her face with some sadness and said, "I'm sorry to bring you to this desperate universe, child, I hope you can live happily." ”

Before entering the game, Luna's sister gave her all her toys, and said with some reluctance on her face, "You have to help me take care of these toys." ”

Then her uncles, uncles, aunts, cousins, cousins...... All into the game.

There were only two people left.

She and her father.

Father was a man with a strong heart.

He is also a great scientist who knows what is about to happen in this universe.

"When this universe continues to shrink and is about to perish, there is about a 1 in 100000000000 chance of survival."

"The energy of the black hole is increasing, and the impact on space will be greater, and finally it may tear the space barrier and form a space-time rift......"

"That space-time rift is the last chance for the immortal dragon civilization to inherit the fire."

"So, we can't give up."

"Even at the last moment before the destruction of the Immortal Dragon, you can't give up!"

Father's words gave Lu Na confidence, and it was her father's many enlightenments that Lu Na, who had proposed to enter that game countless times, did not enter that game cabin. Instead, he stayed.

But three days ago, my father was gone.

The Xianlong was originally an ultra-long starship with a length of one billion kilometers, and the stored matter and energy in it were enough for the population of the 100 billion Xianlong civilization to survive for 1 billion years.

But that's the ideal situation.

Because of the increase in cosmic gravity, in order to resist the pull of gravity, the Xianlong had to sail around the edge of the cosmic barrier.

In the beginning, the speed of the Xianlong was only a few thousand kilometers per second, and in order to fight gravity, the Xianlong had to increase its speed and abandon certain substances on board.

The universe shrinks. The gravitational pull of the black hole increased, and in order not to be sucked in, the Xianlong had to speed up again and again, and throw away some substances again and again.

In the end, the length of the Xianlong was reduced from one billion kilometers to 100 million kilometers, 10 million kilometers, and 1 million kilometers......

Right now. It is less than 100 meters long and weighs less than 500 tons.

The speed of the Xianlong orbiting the center of the universe has reached 0.7 times the speed of light.

According to the laws of physics, the faster the object. The quality will continue to increase.

The reason is that this universe is full of gravitons, and the mass of the spacecraft will naturally increase as it absorbs these gravitons as it travels at high speed.

The quality has increased. The speed will naturally drop.

In the end, the Fairy Dragon will inevitably fly towards the heart of this universe......

And in order to maintain the speed, every once in a while. The Xianlong had to throw out part of its mass, which was converted into engine energy, pushing the Xianlong to maintain an orbit.

No matter how much material reserves there are, there will be a day when they are exhausted.

Three days ago, the Xianlong had used up the last batch of materials that could be used, including those precious commemorative items, some instruments and equipment, and redundant materials.

Lu Na seemed to have expected it, and folded her hands and said to her father, who was rummaging in the cabin: "Father, it's useless, we have no supplies to use, we are speeding up to a black hole, and in about fifty days, we will have a final ceremony of farewell to this universe." ”

"No, no, there must still be a substance, as long as 100 units of substance, you can re-pull the orbit of the Xianlong!"

"What if you have 100 units of matter? This bit of matter will only keep us in orbit for three days, and eventually it will deviate from the increasing mass...... Forget it, father, don't struggle anymore, we can't hold on to the last moment of the destruction of this universe, and we can't fight against the basic laws of this universe. ”

Lu Na said with a desperate expression.

There was even a little relief in her heart, the end was finally coming, and she finally didn't have to feel the feeling of waiting for death and despair anymore.

This may be a relief.

"You're right." The father sat on the ground in frustration and was silent.

However, the next day, when she woke up, she found that her father was gone.

No matter how much you look for it, you can't find it.

Coming to the front of the operation control platform, the number jù shows that the Xianlong is on a stable orbit.

And the captain's chair in which my father and he was riding all disappeared.

Lu Na instantly understood where her father had gone...... In the material reactor at the tail of the Xianlong.

Including his seat, the mass is just a little more than 100 units......

"Luna, don't despair, don't be sad, I'll always be with you."

"For the sake of the Xianlong civilization, for me, for yourself, please live strongly!"

"Don't give up hope until despair comes!"

"I will bless you in heaven."

For a moment, Lu Na's heart was extremely sad, and she immediately cried loudly.

It was only then that she realized how painful it was to cry when she lost her last loved one.

She wanted to die, but seeing her father's extremely resolute eyes in the video, she still didn't take any step.

To this day, the gravitational wave meter has a reminder of Didi, "Discover the gravitational change area, discover the gravitational change area." ”

Lu Na was stunned at first when she saw the red dot, and then realized that the gravitational pull of that area was indeed decreasing.

"Is this the hope that my father is talking about?"
