In the spring of 2523, a more brutal war started again. After mankind relied on the flames and giant shields to build a new insurmountable "high wall", no more people were infected.

The victims have become blood-stained marks that have disappeared in the long river of history.

The survivors still have to inherit the legacy of the deceased and stumble forward shouldering the responsibility of continuing the race to fight against the disaster.

In short, humans completely stabilized their position and then began to counterattack.

New disinfectants have been developed.

Isolation suits of new materials have been developed.

Nuclear fusion energy modules have become smaller and more portable, and can be loaded on individual motorcycles.

People moved forward little by little, slowly pushing the territory occupied by bacteria to the distant coastline.

The recovered persons who were infected with the virus and then barely recovered equipped themselves with semi-mechanized bodies and joined the construction team.

Humanity's defense line began to advance at a rate of several kilometers, ten kilometers or even dozens of kilometers per day.

Although some people will always fall silently on the way forward, those who come after will inevitably take over the equipment he left behind and inherit his will.

The bright red area representing the quarantine area is getting smaller and smaller on the map inch by inch.

The green safety zone belonging to human beings began to increase little by little.

Three years have passed.

Winter 2525.

The Eurasian continent, the American continent, and the African continent successively declared "liberation".

Australia is the only one left.

At the beginning of the disaster, Australia, which was relatively sparsely populated, was unable to organize effective resistance.

It has become a dead territory for humans and has become a paradise for animals and plants.

After a brief respite, in the spring of 2526, after a short period of recuperation, mankind dispatched the first advance team of 100,000 people to form a huge flying fleet and launch a final fierce attack on the S bacteria.

The decisive battle is about to begin.

Billions of people are standing or sitting, holding hands, standing shoulder to shoulder in front of projectors or TVs, or looking down at their mobile phones together.

The picture shows the scene of the advance team landing slowly.

First, the engineering ship sprayed flames to clear and drive away the rats hiding in the ground below.

Whether they were mice or other animals, they fled in a hurry under the heat of thousands of degrees.

This burning process lasted for more than three hours, and all ground animals fled.

Of course, there is not a single rat left that is famous for its agility.

Immediately afterwards, the engineering ship extended its cantilever and began to construct a high-heat isolation zone and a magnetic field shield through external operations.

One day passed, and the advance team established the first base area that once again belonged to humans on the dead Australian continent.

The medical ship took over the position of the engineering ship and began to spray into the air the highly efficient sterilization and disinfection spray that was successfully developed just half a month ago.

Superbugs are constantly evolving, and many disinfection methods that have been tried and tested in the past have gradually lost their effectiveness.

Its drug resistance is getting better and better, its protein shell is becoming more stable and difficult to destroy, and it becomes more invisible after entering the human body. The size of the bacteria has not changed much, but its DNA structure is becoming more and more

complex.

However, humans are not standing still, they are also moving forward.

The new spray worked very well. Ten minutes later, the ship-borne probe was disembarked from the hospital ship and began to collect air in the external environment.

More than twenty minutes later, no trace of S bacteria was detected in the petri dish, which meant that the concentration of S bacteria in this area dropped to 0.

The clean-up operation was a great success.

Then sprinkle a layer of organic powder on the surface of the soil that will release a "foul smell" that is deeply disgusted by all mammals.

After waiting for another half day, high-resolution geothermal imaging confirmed that there was no more warm-blooded mammal in this area.

Stable.

Since then, a green area representing a safe zone has appeared on the world map at the edge of the Australian continent, covering a total area of ​​nearly one square kilometer.

Humanity has established a bridgehead to sound the clarion call for counterattack in Australia, the last stronghold of the S-bacteria.

The engineering ship took action again, opened the material warehouse and began to pile materials on the ground.

These materials will be gradually used by people driving construction machinery to build a second layer of safety cover on the ground.

Next, people will start to build various functional buildings within the safety cover, turning this place into a base with multiple functions such as research, residence, treatment, production, etc.

Engineering staff without isolation suits walked down to the ground on hanging ladders.

All mammals have been driven away. Under the shield of the magnetic field shield, external animals cannot approach in a short period of time. It is no longer possible for S bacteria to exist in this area.

The flamboyant young man smiled proudly, "If the S-bacteria also had a brain, wouldn't it be so angry that it would be so angry when it saw us standing arrogantly in its base camp?"

"Shut your stinky mouth and talk nonsense about some unlucky things? Get to work!"

The experienced middle-aged man scolded him severely.

The young man stuck out his tongue with an expression that he couldn't afford to offend.

Although the atmosphere is still tense, everything is progressing in an orderly manner.

No one expects to achieve success overnight, and everyone is mentally prepared for a long-term war.

Human beings firmly believe that the final victory must belong to themselves.

Everything seems to be going very smoothly.

Another twenty minutes passed, and the peace was suddenly broken.

The alarms in the hospital ship, engineering ship, and personnel transport ship sounded extremely suddenly and at the same time.

All the people who were not wearing isolation suits looked pale and looked at each other speechlessly.

"Why?"

"How is this possible!"

Everyone doesn't understand why.

It's obviously been done perfectly, but why is it still like this?

In just a moment, the vanguard members, whether they were still in the fleet or those who had landed, all fell into the same despair.

Even the few people wearing closed isolation suits are not feeling relaxed.

This feeling of despair and fear can even be completely conveyed to everyone on the planet through live video.

But the panic lasted only ten minutes.

The middle-aged man who had scolded the young man suddenly said loudly.

"Do you still remember the 626 Declaration?"

"Remember!" Everyone agreed in unison.

"So, cheer up! We are the advance team! Are the advance team members afraid of death? I ask you, are you afraid of death?"

"Don't be afraid!"

The middle-aged man nodded again, "Yes, we are not afraid of death. Before setting off, we were already prepared to sacrifice! Death is just dust returning to dust, dust returning to dust! But we will pave the way for those who come after us! Work

!We must find out the reason! Fight to the death and never retreat!"

"Fight to the death and never retreat!"

A day later, the conclusion was drawn.

It was a snake that brought S bacteria out of the ground again and harmed everyone.

Phylum Chordata, subphylum Vertebrates, class Reptiles, class Dipsera, order Snakes.

Australia's S bacteria have evolved again, jumping from rats to snakes.

People began to have a bad premonition in their hearts.

The infected suicide squads once again expanded their search scope and embarked on an unknown journey.

Another three days passed and the final conclusion was released.

The S bacteria here in Australia have evolved to the next stage.

Its infection range goes beyond mice and can infect all vertebrates!

This is too cruel, really too cruel.

Its evolution speed is simply outrageous.

No one knows where the limit of S bacteria is.

Perhaps one day, it will not be spared, along with other species that are microorganisms?

In such a vast world, is there still room for human beings?
