In 2519, after decades of recuperation and development, the Martians built a base covering hundreds of square kilometers, with a total population of over three million.

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

Under this force field shield, 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 Venusians were also born on Mercury and Venus, totaling hundreds of thousands of people.

Humans also have several large space stations orbiting the Earth and Mercury, Venus, and Mars, with as many as 100,000 people and as few as thousands of people in each space station.

The moon has also been fully transformed, and except for the gravity factor, it is very habitable in all other aspects.

Humans have completely broken out of the Earth.

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

In the eyes of ordinary people, it is only a matter of time before they break out of the solar system. Now it is just that the newly established world government wants to achieve success in one fell swoop, so let everyone focus on their own surroundings and develop the resources within the solar system.

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

It all came so fast, so violently and suddenly.

A super bacteria appeared out of thin air.

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

Super bacteria are extremely contagious 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 horrifying.

All these factors combined have led to a result that is almost unbearable for humans.

In the latent stage, no symptoms will be shown at all, and even the comprehensive physical examination of the artificial intelligence medical assistant that everyone is equipped with cannot detect it.

But once it breaks out, the symptoms are very severe, and it may even secrete neurotoxins, causing patients to hallucinate and become manic.

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

This process of gradually moving towards death is almost irreversible.

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

The medical system responded quickly, but soon... it was losing ground.

This was a powerful super bacteria that humans had never seen before.

Almost all antibiotics that humans had mastered were ineffective.

Almost all biological treatment options were ineffective.

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

In the early 26th century, atomic therapy had not yet been born, and humans could not treat patients at the atomic level. Second-level molecular therapy was still in theoretical research. Therefore, when faced with this disease that was completely incurable by biological medical means, humans seemed helpless.

In the early stages of a superbacterial outbreak, the mortality rate was extremely high, and even if forced treatment cured the patient, severe sequelae would remain, rendering the patient incapable of working.

Various antibiotics were used, but all were defeated.

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

is heat-resistant, and its most suitable temperature is 37 degrees. It is also resistant to high salt and can grow in 10% salt water.

It should be so ordinary that it is everywhere, and it does not pose much harm to the human body.

Scientists do not know to what extent it has mutated to produce such a high potential, high lethality, and super-high reproductive lethality.

Its ability to mutate rapidly is completely unlike that of a DNA bacterium.

Facing the pursuit of antibiotics, it only takes half a day for it to develop drug resistance.

Medical staff constantly change antibiotics, and it constantly defeats them.

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

If it finds that the immune system is relatively weak, it will burst out with stronger reproduction and resistance, and finally completely intensify the war with the immune system, leading to the death

of the host. Its pathological characteristics are also constantly changing, and the manifestations are becoming more and more complex. The only thing that remains unchanged is that each pathological characteristic will eventually point to the death of the host.

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

Moreover, under normal circumstances, whether it is a virus or a bacterium, the mutation direction should be towards a direction that is more suitable for transmission and less toxic. This should be an objective law that is unquestionable, just like the sun rising every day.

But this super bacteria violates this common sense.

It did not evolve in the direction of weakening toxicity, but continued to evolve cruelly in the direction of stronger survival in the air, more hidden and stable silent state, milder and more extensive symptoms, and attacking more and more types of human organs.

This is completely illogical, a mutation that increases both transmission and lethality, and it happens very quickly.

As the global outbreaks intensified and then spread unstoppably, conventional human isolation methods became increasingly ineffective.

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

Separation and death happened all the time around the world.

A group of medical personnel fell.

Another group of medical personnel signed a life and death warrant, waved goodbye to their families, and rushed forward. There

were fewer and fewer skilled medical personnel.

Supplies were becoming increasingly scarce.

The air was filled with ubiquitous super bacteria.

They became dust in the air, impossible to prevent and unavoidable.

Order gradually collapsed.

A doomsday catastrophe swept the world silently.

This is a war.

A war that took place before humans and super bacteria, without gunpowder smoke, but more brutal.

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

The number of people killed and sacrificed on this white battlefield is ten times or a hundred times the sum of all other types of wars combined.

This time, it is particularly brutal.

Humanity is losing ground.

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

Fear permeated the world, and humans had no place to retreat.

If they could survive, no one would choose to die.

But there are always some people who understand that they cannot retreat and must go to the top.

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

The world government, which is still in its infancy, abandoned all prejudices at the fastest speed and reached a unified consensus in just a few days.

Humanity must unite without reservation and declare war on this disaster.

Only by defeating the enemy can humanity survive!

The leader jointly recommended by the leaders of all countries in the world stood up.

He rushed to the front line and issued a resounding cry.

"Humanity has a history of millions of years. Our civilization has a history of 5,500 years! We are always fighting, fighting ourselves and fighting nature."

"We will always face failure, but we will always stand on this planet in the end. We are called the cancer of the earth by environmentalists. 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? Stubbornness! Never give up! Never give up!"

"We are facing an unprecedented challenge. This is not a personal matter, but a common challenge for all mankind! It is time for us to unite!"

"The front line needs warriors, more warriors! We can't let the medical staff sacrifice in vain, more people must stand up and take over the trenches they once guarded! Defend the position that belongs to all mankind!" "

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

"We must deliver protective clothing, masks, goggles, and medicines to the hands of frontline warriors one by one!"

"Wear your mask, goggles, and gloves, and never touch your eyes, nose, ears, and mouth with your hands without washing your hands. Take all the protective measures you can, stand at your post, and fight!"

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

"Survival, or extinction? It depends on everyone's choice! Make your choice! One step back is extinction, one step forward is a new life! Charge!"

This speech came hastily, without careful craftsmanship, and the wording was mediocre, but it was sincere and heartfelt, igniting the survivors' fighting spirit in the overwhelming despair.

When the leader spoke, the Wei River was behind him.

Later generations called this speech the "Back to the Water Declaration."

The Back to the Water Declaration wiped out everyone's mentality of surviving, and made everyone understand that mankind is on the edge of a cliff and in a situation of a last-ditch battle.

No one can be immune.

Humanity has nowhere to retreat!

Isolation wards and hospitals are ineffective, so humanity creates quarantine zones!

Large areas of healthy people are evacuated.

Everyone keeps a physical distance from everyone on the street, but only needs a distant eye contact to understand each other's intentions.

At this moment, everyone is a comrade-in-arms with the same hatred and enemies.

Everyone understands that everyone standing outside like themselves has a family behind them that they must support.

The young men and women in each family have each chosen the position they want to take.

More and more people, knowing the danger, are receiving basic medical training. After less than a month of assault training, they pass the assessment, put on isolation suits, masks, gloves, and goggles, and endure the sweltering heat to rush to the front line.

Sweat soaked the soldiers' clothes.

Tears flowed, but everyone gritted their teeth and fought to the death.

However, the super virus is too strong.

The scope of the isolation area is getting bigger and bigger, and the front line is moving back little by little.

The area of ​​the isolation area marked in red on the map is getting bigger and bigger.

Human beings fight and retreat, but never collapse.

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

Even if there really is a doomsday, we will sing the last battle song.

Just as Master Zhong Lei sang in "Bath of Fire", as long as we never give up hope, there will be a day when we will be reborn from the ashes.

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

Someone will come to take over my trench, and I will not sacrifice in vain!

Definitely!

One year later.

Humanity finally successfully demarcated the territory and established a complete isolation zone.

The scope of human activities has changed from being all over the world to less than two-thirds of the territory left.

This year, the entire human race lost more than 10% of the total population. The price paid was so tragic that it was eye-catching, but it finally stabilized its position.

But it is still not the moment to be careless.

Without anyone reminding us, everyone knows that we cannot relax, and we must not abandon the medical staff, volunteers, and patients who sacrificed themselves to protect the territory in the quarantine zone.

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

The war is still going on, and it has even become more intense.
