In 2519, after decades of recuperation and development, the Martians built a base covering a total area of hundreds of square kilometers, with a total population of more than 3 million.

The main building structure of the base is composed of hundreds of force field shields.

Under the shield of this force field, people planted farmland, laid solar energy equipment, and built factories, research institutes, hospitals, schools, business areas and accommodation areas, forming basic urban functions.

In addition to Mars, mercury and Venus were also born on mercury and Venus, a total of hundreds of thousands of people.

Humans also have several large space stations around the earth, mercury, Venus and Mars, with more than 100000 people and less than thousands of people in each space station.

The moon has also been completely transformed. It is livable in all aspects except gravity.

Mankind has completely rushed out of the earth.

Although it is impossible to leave the solar system, ordinary people do not fully know it.

In the eyes of ordinary people, it's sooner or later to rush out of the solar system. Now it's just that the newly established world government wants to finish its work, so let's focus on our side and develop the resources inside the solar system.

However, since the beginning of the winter of 2519, cataclysm has occurred on the earth and spread to every human base.

All this came so fast, so fast and suddenly.

A superbug appears out of thin air.

No one knows where it was first born. When human beings react, it has spread all civilization in a very short time.

Superbacteria are extremely infectious and have an amazing ability to divide and proliferate rapidly.

At the same time, its incubation period is extremely long, reaching half a year, which is simply appalling.

The combination of various factors has led to results that human beings can hardly bear.

In the latent stage, it will not show any symptoms at all, even the comprehensive physical examination of the artificial intelligence medical assistant equipped by everyone can not be detected.

But once it occurs, the symptoms are very violent, and even secrete neurotoxic interference, causing patients to hallucinate and become manic.

And the cycle from attack to death is as long as two months. In these two months, the patient will gradually lose the ability to move and eventually die.

This gradual process towards death is almost irreversible.

When the first patient broke out less than two days later, tens of millions of people around the world broke out together in a short time.

The health care system responded quickly, but soon... It fell back.

This is a powerful superbacterium that humans have never seen before.

Almost all the antibiotics that humans have mastered have failed.

Almost all biological treatments are ineffective.

In the absence of effective treatment, we can only rely on personal immunity.

At the beginning of the 26th century, the atomic therapeutic instrument had not yet been born. Human beings could not treat patients from the atomic level, and the secondary molecular therapeutic instrument was still in theoretical research. Therefore, in the face of this disease with no way of biological medical means, human beings seemed helpless.

In the early stage of superbacteria outbreak, the mortality rate is very high, and even if forced treatment is cured, it will leave serious sequelae and make people lose their ability to work.

All kinds of antibiotics went up and all failed.

It is clearly a DNA bacterium, and its biological indexes are close to Staphylococcus aureus.

It is heat-resistant, and the most suitable temperature is 37 degrees. At the same time, it is resistant to high salt and can grow in 10% salt water.

It should be ordinary to be everywhere, and it doesn't do much harm to the human body.

Scientists do not know to what extent it has mutated to produce such high latent, high lethal and ultra-high reproductive lethality.

Its ability to mutate rapidly is nothing like a DNA bacterium.

In the face of the pursuit of antibiotics, it only takes more than half a day to develop drug resistance.

Medical staff constantly change antibiotics, and it continues to defeat antibiotics.

In the face of the counterattack of the human immune system, it becomes extremely cunning. If the human immune system is strong, it will assimilate more deeply enough to deceive the immune system and enter a deep incubation period.

If it finds that the immune system is relatively weak, it will erupt into stronger reproductive ability and resistance, and finally completely intensify the war with the immune system, leading to the death of the host.

Its pathological features are also changing, and its manifestations are becoming more and more complex. The only constant is that each pathological feature will eventually point to the death of the host.

Its rapid variation and stubborn characteristics make it almost impossible to develop specific drugs and vaccines.

Moreover, generally, the variation direction of both viruses and bacteria should be more suitable for transmission and less toxic. This should be an objective law that is indisputable as the sun rises every day.

But this superbug goes against this common sense.

It does not evolve in the direction of weakening toxicity, but continues to evolve cruelly in the direction of stronger vitality in the air, more hidden and stable silent state, more gentle and extensive onset symptoms, and more and more types of human organs attacked.

This is completely illogical. The variation of both transmissibility and lethality is enhanced, and it is very fast.

With the concentrated outbreak all over the world and then the unstoppable proliferation becoming more and more intense, the conventional means of human isolation are becoming more and more difficult to work.

Batch after batch of medical personnel fell on the front line.

Life and death take place all over the world.

A group of medical staff fell.

Another group of medical staff signed a life and death certificate, waved goodbye to their families and rushed up.

There are fewer and fewer skilled medical personnel.

Supplies are becoming more and more scarce.

The air is filled with ubiquitous superbacteria.

They become dust in the air, which is impossible to prevent and unavoidable.

Order gradually crumbled.

A doomsday catastrophe swept the world silently.

This is a war.

A more tragic war without gunpowder before humans and superbacteria.

In the long and long history of mankind, we have never faced diseases many times.

The number of people killed and sacrificed on this white battlefield is 10 times and 100 times that of all other types of wars combined.

This time, it was particularly tragic.

Human beings are falling back.

Later, medical students went up, and volunteers who had received short-term systematic training also went up.

Fear pervades the world, and mankind cannot retreat.

If you can live, no one will choose to die.

But there will always be some people who understand that they can't retreat and must go up.

Throw aside the concept of country and country and all the so-called feelings, people will always realize that if no one stops the disaster and allows the disaster to spread and develop, all their relatives and friends, such as their parents, children, grandparents and so on, will have to face all this day.

The budding world government abandoned all prejudices as quickly as possible and reached a unified consensus in just a few days.

Mankind must unite unreservedly and declare war on this disaster.

Only by defeating the enemy can mankind survive!

The leaders jointly elected by the leadership of all human countries stood up.

He rushed to the front and shouted an enlightening cry.

"Mankind has a history of one million years since its birth. Our civilization also has a history of 5500 years! We are always fighting against ourselves and nature."

"We always face failure, but we always stand on this planet in the end. We are called the cancer of the earth by environmental protectors. Well, we admit that we are cancer. This bacterium is the antibiotic of the earth. It wants to destroy us. But what is the characteristic of cancer? It is stubborn! It never gives up! Never give up!"

"We are facing an unprecedented challenge. It's not a personal matter, it's a common challenge for all mankind! It's time for us to unite!"

"The front line needs soldiers and more soldiers! Medical personnel cannot be sacrificed in vain. More people must stand up and take over the trenches they once guarded! Stick to the positions belonging to all mankind!"

"Our logistics resources must keep up! We can't let soldiers go to the front without equipment! We need people from all walks of life to return to their posts, and our social order must operate!"

"We must send one protective suit after another, masks, eye masks and medicine to the front-line soldiers!"

"Wear your mask, eye mask and gloves. Never touch your eyes, nose, ears and mouth with your hands without washing your hands. Take all possible protective measures, stand at your post and fight!"

"Wave goodbye to your family and go to the front! Every post is everyone's battlefield! Gentlemen, stand up! For yourself, for your family and for mankind!"

"Survival, or death? It's everyone's choice! Make your choice! One step back is death, and one step forward is rebirth! Charge!"

This speech came in a hurry, not carefully crafted, and the wording was mediocre, but it was sincere, which ignited the fighting spirit of the survivors in the overwhelming despair.

When the leader spoke, behind him was the Weishui river.

Later generations will call this paragraph "back to water declaration".

The backwater declaration extinguished everyone's fluke and made everyone understand that mankind is on the edge of a cliff and in a situation of backwater battle.

No one can be alone.

Human beings can't retreat!

Isolation ward and hospital are invalid, human beings create isolation area!

Large areas of healthy human evacuation.

Everyone keeps a physical distance from everyone on the street, but it only takes a distant intersection of eyes to understand each other's mind.

At this moment, everyone is a comrade in arms who shares the same hatred.

Everyone knows that everyone who stands outside like himself has a family behind him.

The young men and women in each family have chosen their own posts.

More and more people, aware of the danger, also went to receive basic medical training. After less than a month of surprise training, they reached the standard. Then they put on isolation clothes, masks, gloves and glasses and rushed to the front line with the torment of heat.

Sweat soaked the soldiers' clothes.

Tears trickled down, but everyone gritted their teeth and insisted on fighting to the death.

But the super virus is too strong.

The area of separation is becoming larger and larger, and the front is moving back a little bit.

The isolation area marked in red on the map is becoming larger and larger.

Mankind fought and retreated, but never collapsed.

Because everyone knows that since ancient times, human beings have never died on their knees!

Even if there is the end of the day, we will sing the last war song.

As master Zhong Lei sang in "bath fire", as long as we never give up hope, there will be a day of rebirth.

Even if I die in battle, even if my ashes are buried deep in the bottom, my family will see the dawn!

Someone will take over my trench. I won't die in vain!

certain!

One year later.

Human beings finally succeeded in drawing the land as the boundary and established a complete isolation zone.

Human activities range from all over the world to less than two-thirds of the territory.

This year, mankind lost more than 10% of its total population. The price paid was painful and eye-catching, but it finally stabilized.

But there is still no time to take it lightly.

Without being reminded by others, the world knows that we can not relax, let alone give up the medical personnel, volunteers and patients who have sacrificed their lives to protect their territory in the isolation area.

The will of the great will be inherited by the same great me!

The war continued and even became more intense.
