In 2519, after decades of recuperation and development, the Martians built a base covering a total area of several hundred square kilometers, with a total population of more than three 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 equipment, built factories, research institutes, hospitals, schools, commercial areas, and accommodation areas, forming basic urban functions.

In addition to Mars, Mercury and Venus were also born on Mercury and Venus, totaling hundreds of thousands of people.

Humans also have several large space stations orbiting Earth, Mercury, Venus, and Mars, each with a maximum of 100,000 people and a few thousand.

The Moon has also been completely revamped and is habitable in every way except for the gravitational factor.

Humanity has completely swept away from the earth.

Although it is impossible to leave the solar system, it is not fully aware of it in ordinary people.

In the eyes of ordinary people, it is a matter of time before they rush out of the solar system, and now it is just a matter of the newly established world government wanting to finish its work, so let everyone focus on the surroundings first and develop the resources inside the solar system.

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

It all came so fast, so swift and so sudden.

A superbug appears out of thin air.

No one knows where it was first born, but by the time humans reacted, it had spread throughout civilization in a very short period of time.

Superbugs are extremely contagious and have an amazing ability to divide and multiply quickly.

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

All these factors have combined to lead to results that are almost unbearable for human beings.

In the latent stage, they do not show any symptoms at all, and even a comprehensive physical examination of the AI medical assistant equipped by everyone cannot be detected.

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

The period from onset to death is as long as two months, during which the patient gradually loses the ability to move and eventually dies.

This gradual process towards death is almost irreversible.

Less than two days after the first outbreak, tens of millions of people around the world broke out in a short period of time.

The healthcare system reacted quickly, but quickly ...... and retreated.

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

Almost all the antibiotics that humans have mastered have failed.

Almost all biologic treatment regimens are ineffective.

In the absence of an effective treatment plan, it can only be resisted by the individual's immunity.

At the beginning of the 26th century, the atomic therapy device had not yet been born, and human beings could not treat patients from the atomic level, and the second-level molecular therapy device was still in theoretical research, so in the face of this biomedical means of no way to do the disease, human beings seemed helpless.

In the early stages of a superbug outbreak, the mortality rate is extremely high, and even if it is cured by forced treatment, it will leave serious sequelae and make people incapacitated.

All kinds of antibiotics went up, and they all failed.

It is obviously a DNA bacterium, and its biological indicators are close to that of Staphylococcus aureus.

It is heat-resistant, and the optimum temperature is 37 degrees, and it is also resistant to high salt, and can grow in brine with a concentration of 10%.

It should be so ordinary that it is ubiquitous, and it is not very harmful to the human body.

Scientists don't know what kind of mutation it has undergone to produce such a high latent and lethal and ultra-high reproduction lethality.

Its ability to mutate quickly is not at all like a DNA bacterium.

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

The medical staff keeps changing the antibiotic, and it keeps beating the antibiotic.

In the face of the counterattack of the human immune system, it becomes extremely cunning again, and if the human immune system is strong, then it is deeply assimilated enough to deceive the immune system and enter a deep incubation period.

If it finds that the immune system is relatively weak, it will burst out with stronger reproductive ability and resistance, and eventually completely intensify the war with the immune system, resulting in the death of the host.

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

Its rapid mutation and stubborn nature make it almost impossible to develop specific drugs and vaccines.

Moreover, under normal circumstances, the direction of mutation of both viruses and bacteria should be carried out in a direction that is more suitable for transmission and less virulent, which should be as undoubted as the objective law of the sun rising every day.

But this superbug defies that common sense.

It has not evolved in the direction of weakening its toxicity, but has continued to evolve in the direction of being more active in the air, the silent state more subtle and stable, the symptoms of attacks more mild and widespread, and the types of human organs attacking more and more.

This is completely illogical, a mutation that is both transmissible and lethal, and extremely fast.

As the global outbreaks intensify into unstoppable dispersions, the conventional methods of human isolation are becoming less and less effective.

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

Life and death happen all over the world all the time.

A group of medics fell.

Another group of medical personnel signed the life and death certificate, waved goodbye to their families, and rushed forward.

There are fewer and fewer skilled medical personnel.

Supplies are becoming more and more scarce.

The air is filled with ubiquitous superbugs.

They become fine dust in the air, which cannot be prevented and cannot be avoided.

Order is gradually collapsing.

An apocalyptic catastrophe has swept the world silently.

It's a war.

A war that took place before humans and superbugs, without gunsmoke, but even more tragic.

In the long history of mankind, we have faced diseases countless times.

The number of people killed and killed on this white battlefield is ten times and a hundred times greater than the sum of all other types of warfare combined.

This time, it was particularly tragic.

Humanity is retreating.

Later, medical students went up, as did volunteers who had undergone a short period of systematic training.

Fear pervades the globe, and humanity has no way back.

If they lived, no one would choose to die.

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

Putting aside the concept of country to country, putting aside all the so-called feelings, people will always realize that if no one stops the disaster and allows it to spread, then their parents, children, grandparents, and all other relatives and friends will have to face all this day one day.

The nascent world government discarded all preconceptions as quickly as possible and reached a unified consensus in just a few days.

Humanity must unite unreservedly and declare war on this catastrophe.

Only by defeating the enemy can humanity survive!

Leaders who have been elected by the leadership of all human countries have come forward.

He rushed to the front and let out a deafening cry.

"Mankind has a history of millions of years since its birth. The history of our civilization is also 5,500 years! We are always in opposition, against ourselves, against nature. ”

"We always face failures, but we always end up standing on this planet. We are self-proclaimed by environmentalists as the cancer of the planet. Well, we admit it, we're cancer. This bacterium is the earth's antibiotic. It's going to destroy us. But what are the characteristics of cancer? It's stubborn! It's never say never! Never give up! ”

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

"The front line needs fighters, more fighters! Medical personnel must not be sacrificed in vain, more people must stand up and take over the trenches they once guarded! Hold the ground that belongs to all mankind! ”

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

"We must deliver one protective suit, one after another, masks, eye masks, medicines to the frontline fighters!"

"Wear your mask, blindfold, gloves, and never touch your eyes, nose, ears, or mouth without washing your hands. Do all the protective measures that can be done, stand in your position, and go to struggle! ”

"Wave goodbye to your family and go to the front! Every post is a battlefield for everyone! Gentlemen, stand up! For yourself, for your family, for humanity! ”

"To live, or to perish? It's everyone's choice! Make your choice! One step back is perdition, one step forward is rebirth! Charge! ”

The speech was hasty, unpolished, and banal in wording, but it was heartfelt, igniting the fighting spirit of the survivors in the midst of overwhelming despair.

When the leader spoke, it was the Weishui River behind him.

Later generations referred to this passage as the "Declaration of the Backwater".

The Declaration of the Backwater extinguishes everyone's luck and makes everyone understand that humanity is on the edge of a cliff and is in a situation of fighting against the water.

No one is immune.

There is no way back for humanity!

Isolation wards and hospitals are ineffective, and humans create quarantine areas!

Large areas of healthy human evacuation in large areas.

Everyone is physically distancing themselves from everyone on the street, but it only takes a glance at each other to understand each other's minds.

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

Everyone understands that everyone who stands on the outside like themselves has a family behind them that must be carried.

The young men and women in each family have chosen their own positions that they want to occupy.

More and more people, knowing that there is danger, also go to receive basic medical training, after less than a month of surprise training, the assessment is up to standard, and then put on isolation gowns, masks, gloves, glasses, and endure the stuffy torture and rush to the front line.

Sweat soaked the soldiers' shirts.

Tears flowed, but everyone gritted their teeth and held on, fighting to the death.

However, the super virus is just too powerful.

The scope of the quarantine zone is getting bigger and bigger, and the battle line is moving back little by little.

The area of the quarantine zone, marked red on the map, is getting larger.

Humanity fought and retreated, but never collapsed.

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

Even if there is a day of doom, we will sing the last battle song.

As Master Zhong Lei sang in "Bathing in Fire", as long as we never give up hope, there will be a day when we will be reborn from the fire.

Even if I die on the battlefield, even if my ashes are buried deep in the ground, my family will definitely see the light of day!

Someone will come and take over my trenches, and I won't die in vain!

Certain!

A year later.

Mankind has finally succeeded in drawing the boundaries of the earth and establishing a complete separation zone.

Human activity has ranged from global to less than two-thirds of its territory.

This year, humanity lost more than 10 percent of its total population, and the price paid was staggering, but it finally held its ground.

But it's still not the time to take it lightly.

There is no need to be reminded by others, and the world knows that we cannot relax, let alone give up on the medical staff, volunteers, and self-sacrificing patients who have defended the territory with their lives in the quarantine zone.

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

The war continues, and even becomes more intense.
