On a blue, vibrant planet, dozens of huge spaceships are moored on land, a large amount of cargo is being transported into the spaceship, everyone has a sad look on their faces, and even many people are crying.

Outside the spaceship, a man sat in a wheelchair and watched the scene in front of him, his body was thin, although he was only in his forties, but the disease made him look like a rare person, and everyone could see that his life was short.

"Professor Liu, the last group of humans has boarded the ship, let's go too!"

A soldier in a navy blue military uniform ran up to the man in a wheelchair and said.

"All on board? Okay, let's go, let's go! ”

The man in the wheelchair replied weakly.

"Okay, let's go together!"

The soldier stepped forward and pushed the wheelchair as he spoke.

"Let go......... I said, let's go, I'm not going to leave here! ”

The man in the wheelchair had a weak voice, but he was extremely determined.

"Professor Liu, you ......!"

The other party was stunned for a moment, and immediately reported the situation here.

"Professor Liu, you can't stay!"

A virtual image was projected beside him, a middle-aged man in a military uniform with a dignified appearance.

"Generalissimo, this is my home, I, like Lao Sun and Lao Zhang, are willing to stay, and the Human Alliance has no right to interfere!"

The man in the wheelchair smiled.

"Professor, you are a hero of mankind, without you, humanity will suffer a catastrophe!"

The other party shouted at him.

"Doom? Hehe, we humans have suffered a catastrophe, and I just have a glimmer of hope for more compatriots......... It's my responsibility, and now that my responsibility is done, it's up to you...... Generalissimo, my time is short, and I do not want to leave my homeland again, so go away, take with us the last hope of mankind, and tell our children that we must not forget this painful lesson......... Let's go, let's go! ”

After speaking, the man ignored the other party and controlled his wheelchair and walked towards a small plane not far away.

"Professor......!"

The generalissimo wanted to say something, but the words that came to his mouth were swallowed alive and again, and then the image disappeared .......

The little plane took off into the distance, and in a few moments it flew into a city that was deserted, and there was not a single person in sight on the streets.

The plane landed on a building, the door opened, and the man in a wheelchair followed the elevator to his room, where he had worked and lived for nearly twenty years, and everything was still in the same place.

"Lao Sun, Lao Zhang, I, Lao Liu, are also here to accompany you."

The man said with a smile, and the wall in front of him turned into a screen with two old faces on it.

"Lao Liu, you didn't leave?"

The two were surprised.

"Let's go? This is our home! Once we leave, we old guys will never have a chance to come back. ”

"Hehe, that's right, Lao Zhang, don't look at Lao Liu's age younger than my son, but his body is probably the biggest among the three of us, you and I have to call him big brother!"

"Haha, yes, the three of us have been working together for more than 20 years, I still remember when we first met, Lao Liu was still Xiao Liu, and in the blink of an eye, twenty years have passed, and we humans still haven't defeated the enemy after all, alas, .........!"

An old man let out a long sigh.

"Fortunately, there is Lao Liu! It was he who invented the black alloy that could allow more people to escape, and I believe that humanity will one day come back .........! ”

The man in the wheelchair looked up at the sky and saw several ships as large as small cities slowly rising into the sky in the distance, gradually disappearing into the starry sky.

"The hope of mankind depends on you.........."

The burden was put down, he closed his eyes, and all kinds of past events came to mind.

His name is Liu Yuetian, he is a physicist, he is only forty-two years old this year, but he has been known as the most famous physicist in the past hundred years, but he has suffered from a disease since he was twenty years old, and the aging rate of his body is much faster than that of ordinary people.

Liu Yuetian still remembers that in the year when he learned that he was suffering from this terminal disease, human beings discovered the Luke Star civilization in a star system three light years away, which was the first time that human beings had contact with other civilizations, but it was a catastrophe for human beings.

A war began between the two civilizations that lasted for more than ten years, and the human army was constantly destroyed in the great war, even though the fleet of the Rooker civilization also suffered heavy losses, but as time went on, the Rooker civilization became the ultimate victor.

Lukexing creatures generally have low intelligence, only one in 100,000 creatures will have such intelligence as humans, and the level of science and technology formed by the development of this civilization for hundreds of thousands of years is barely higher than the level of science and technology of human development for two thousand years, if you give humans another fifty years, human science and technology will catch up with them, and give humans another hundred years, they will be crushed.

Even the current human race once had the hope of defeating the Rooks and achieving the final victory, but selfishness and greed eventually ruined the human .......

The wisdom of human beings is stronger than that of the Rooks, which seems to be the biggest advantage, but the intelligent human beings have only known to fight for their own race and their own country since the day they were born into civilization, even in the era before meeting the Rooker civilization, human society is still composed of hundreds of countries, three of which are the most powerful, although the countries and countries maintain peace, but they also compete with each other, everyone wants to become the first power of mankind, this competition means that the power of human beings has never been able to cohesion.

On the other hand, the Rukh Star civilization is led by a group of supreme god-like nobles who lead hundreds of millions of people, the nobles have higher intelligence than the commoners, and the civilians work like ants, although the society has developed slowly, but it has never stopped, and has been developing for more than 200,000 years, and finally this "stupid" civilization has come out of the Rooker Star in order to find a new habitable planet.

The Rooks discovered the Earth civilization after traveling through the universe for hundreds of years, and the blue planet was very similar to their homeland, so they decided to take over the Earth, and the two civilizations began a life-and-death war.

The entire Lukxing civilization is a country, no one will resist the orders of the nobles, and those warriors are like ants who are not afraid of life and death, even if they are swords and fires.

On the other hand, human beings, the fleets of various countries are playing their own calculations, no one wants to suffer greater losses than other countries, and as a result, many good opportunities have been missed, so that it has come to the point of no return, and now human beings have established a unified alliance, and there will be no countries and races from now on, but it is too late, the human fleet has been lost, and the fleet of Lukstar is heading towards the earth at the speed of thirty percent of light.

Fortunately, ten years ago, Liu Yuetian created the black metal after analyzing the enemy's starship data, which can be used to build larger spaceships, super ships that can carry millions of humans at a time.

In ten years, mankind has exhausted countless materials and finally built four spaceships, and more than 10 million humans can finally leave the earth and go on a long journey to find the next planet suitable for human habitation.

"The warship of the Ruke civilization has entered the solar system and is flying towards the Martian base, and it is expected to arrive in ......... in three days!"

The sound of the prompter sounded, waking up Liu Yuetian, who was stuck in memory.

"Coming, coming.........."

Mars and Earth are two planets inhabited by humans, and even though tens of millions of people leave on super battleships, there are still nearly 10 billion humans who can't leave.

"There was a nuclear explosion in the third human settlement area of the Mars base, and the death toll was found to be more than 300,000 .........."

"A nuclear explosion occurred in the fifteenth inhabited area of the Mars base, killing more than 230,000 .........."

"A nuclear explosion occurred in the 36th inhabited area of the Mars base, killing more than 180,000 .........."

…………

The prompt sound kept ringing, Liu Yuetian closed his eyes in pain, Luke's creatures are like beasts, if they catch the enemy, they will eat them, and the humans who do not leave can only detonate the nuclear bomb.

In just three days, the entire Mars was covered with dust, and even if the Ruke civilization came, it would take decades to regain its former vitality, which also gave enough time for those fleeing humans.

"Are you coming?"

Liu Yuetian was lying in a wheelchair, opened his eyes with all his strength, and saw the sun outside, this star has been burning for six billion years, giving birth to human life, although the weak human life in front of the stars is so short, but Liu Yuetian firmly believes that the inheritance of human beings will not be broken, and will extend infinitely until the end of the universe ..........

A dazzling light flashed, and Liu Yuetian's consciousness finally returned to ......... eternal silence.
