During the five hundred years from 2020 to 2520, Chen Feng and the Salvation Army strictly implemented all the steps set out in the "Five Hundred Years Plan", and in the last twenty years, they condensed the essence and broke out.

The rapid evolution of various military equipment and medical technologies gave people great confidence, and they firmly believed that no matter whether they encountered Z bacteria or S bacteria this time, humans had the ability to win the battle.

Because in these twenty years, in addition to rapidly advancing technology and digesting the last wealth in the sixteen chapters of the Salvation Army ("Madman's Conjecture Collection" 1.0 to 16.0), humans also did their best in other aspects.

Rapidly build a pan-solar system "Morrowind" player, massively store personal health protection resources, implement a dispersed living strategy of one room per household and one house per person, and try to transfer social interactions to the holographic world of quantum networks. Develop vaccines in advance, but do not inject them. Just distribute them in the form of one needle per person. The small syringe is hidden in everyone's smart auxiliary watch.

Focus on the development of space-level individual combat equipment as much as possible, gradually improve the performance of the galaxy armor, and clear animals from space units such as space stations and ships that do not have strategic depth in advance, and even bacteria, fungi and viruses are not spared.

If it were not for the fact that the symbiotic bacteria in the human body have formed a subtle and complementary symbiotic system with the human body, these microorganisms in humans would probably not be spared.

By the end of 2519, the microbial monitoring systems in planets, settlements, space stations and ships throughout the solar system had been operating stably for more than ten years, and the monitoring algorithms were changing with each passing day, and the performance was constantly improving, but there was still no movement.

Time unknowingly entered the year 2520.

On January 7, 2520, the top leadership meeting of the five major fields of human science, politics, economy, industry, and military made a judgment.

This time it was still not S bacteria.

The answer was obvious, it must be Z bacteria.

The vaccine for S bacteria still needs to be injected, after all, this can further bring about the improvement of genetic awakening, and after the innovation of medical and biotechnology, the survival rate is also quite guaranteed.

At the same time, mankind fell into another ethical dilemma.

Should we kill animals in advance to reduce species diversity and reduce the threat of organisms?

After all, the potential ability of Z bacteria is exaggerated.

In the end, the top level of the world government at that time came up with a foolproof method.

All the people on Earth were launched into space, and their residences were transferred from the surfaces of major planets and satellites to large space bases.

Space sterilization was implemented in the space base, and all animals were kept in captivity on the surface of the planet.

At the same time, humans only stationed elite troops on the ground, responsible for maintaining order and being on standby at all times, while monitoring and repairing some artificial intelligence production machinery.

According to everyone's common sense, humans have several absolute advantages.

First, once Z bacteria begin to be born, with the performance of the global microbial monitoring system, it can be discovered at the first time and eliminated at a fixed point.

Second, even if the Z bacteria were to reproduce successfully, and begin to grow latently and catalyze the mutant extinct animals, the Galaxy Warriors' individual combat capabilities could easily suppress the enemy with only the fighting power of the Blue Dragon Armor.

Although humans in this era also have powerful snowflake battleship technology, the focus is completely on the Galaxy Armor. After all members were injected with the S bacteria vaccine, 16 billion people supported 6 million Galaxy Warriors.

Judging from Chen Feng's perspective, although the performance of this set of Galaxy Armor is not as good as the real Galaxy War Pill he used, it is not inferior to the Eagle Strike Armor series. It seems to be a sure win.

Third, even if the mutant animals this time surpass the ability of the extinct animals described by the sage Chen Feng, humans can also launch powerful space-based cannons on the space station to carry out targeted strikes on the ground and regional cleanup.

It took humans only two years to complete this major shift that can create a strategic depth. They temporarily gave up the planet and waited and saw what would happen.

At the beginning, the direction of things was under control.

It's just that the time node was slightly different, and this time the time was slightly advanced.

According to Lai Wenming and Sergei's speculation, the control bacteria should have appeared on the earth as early as 2531 and gradually multiplied.

But the strange thing is that the global microbial monitoring system that was highly expected was completely unaware.

In the early days of the disaster, scholars could not figure out the problem.

It was not until many years later that the lonely Sergei calculated the answer.

The physical rules in the solar system were tampered with, causing the monitoring equipment that relied on gravitational waves, electromagnetic waves, bioelectric fields and other functions to perform complex scanning to lose its effectiveness.

Then, in the winter of 2540, a large number of mutant animals suddenly appeared and took the lead in attacking the military base on Earth.

But no one panicked at this time, and people were relieved instead.

Hua Zhongyun said confidently at the first "Great Catastrophe" war mobilization meeting: "The judgment of the sage Chen Feng is completely correct! This time, it is the Z bacteria that control animals to invade humans. With the military strength we currently have, we can almost declare victory in the war in advance. I order to sweep away the animals on the major planets as quickly as possible, restore production, and restore the system. Our main task this time is not these ant-like mutated animals in front of us, but the solar dome that is shrouding our heads!"

The members in the conference room who also belonged to the savior and held important positions in various fields nodded one after another.

Yes, this is not only our judgment, but also the judgment of the sage Chen Feng who can see through time and predict the future.

Thanks to the sage, he has made perfect preparations for us.

He protected mankind and saved us from the hardship of the initial war.

The war started.

The Galaxy Warriors who stayed on the ground had an overwhelming advantage when facing the mutants, and easily gained the advantage in the war with one enemy and many enemies.

The mutants were quickly suppressed and slaughtered.

After just two years, the threatening large mutants on the ground were almost eliminated, and victory was in sight.

Of course, in this good situation, there will always be some not-so-harmonious "rationalists" who force themselves to make discordant voices.

A typical representative is Lai Wenming, a biologist who is famous both at home and abroad and has made outstanding contributions.

He has raised new concerns more than once.

He firmly believes that Z bacteria may also affect humans and should not be taken lightly.

He hopes that when fighting the enemy, the soldiers will pay more attention to self-isolation and protection, and the soldiers should also maintain a safe distance and self-isolation from each other.

At the same time, Lai Wenming also opposes the easy return of ground troops to large space stations for rest, and opposes the transportation of supplies under low protection levels.

Even if the soldiers must rest, a separate isolation space station should be established so that those who have returned to Earth can only move in the space station.

If supplies are to be transported to the isolation space station, the disinfection mode must also be strictly implemented.

Lai Wenming and dozens of other scholars who were still highly respected at the time proposed this idea more than once and formulated a very strict comprehensive protection strategy.

Unfortunately, Lai Wenming's proposal was not passed unanimously and implemented firmly.

Most mainstream opinions at the time believed that this was the intelligence that our previous generation had exchanged for their lives, and it was also the golden rule passed down by the ancient sage Chen Feng with iron-clad facts. How could it be wrong?

The ability of the solar dome is limited, so Z bacteria can only be Z bacteria, not S bacteria. How can it be transmitted to humans?

Besides, we have not lowered the monitoring of the immunity of the warriors. Isn't this a problem?

Of course, Lai Wenming's words did have some effect, and humans raised the protection level to a certain level.

But one item was rejected.

Although the Galaxy Warriors are very strong, the number of mutant animals is huge, and they are organized and have some strange tactics, so the Galaxy Warriors are still inevitably injured.

The warriors are already tired enough from charging into the formation, and the sacrifices are great enough. You still don't let them reunite with their families during the rest time. Isn't this chilling?

But even so, Lai Wenming's request was approved. From February 2540 to January 2542, a period of one year and eleven months, the warriors really didn't see their families once.

Even if there were occasional contact, all the contact personnel were sent to a temporary isolation space station.

It was not until the autumn of 2542 that the war situation changed slightly.

The reproductive capacity of the mutant animals suddenly increased, and their regeneration ability was also improved.

Some of the mutant animals that had been broken into pieces and turned into rotten meat piled on the ground were reunited and integrated to form new hybrid creatures, which looked like the stitched abominations in European and American fantasy stories.

It seems that in order to destroy the opponent, its organic tissue must be completely decomposed and reduced to pure low-level particles.

Now the war that seemed to be able to be resolved quickly has to be prolonged, and Lai Wenming's previous strong isolation policy has been opposed.

Many soldiers said that they had not seen their families for almost two years. They were really tired, exhausted, and mentally exhausted.

And they had never relaxed their personal medical tests. We really had no problem.

This was undoubtedly the Z bacteria. The quarantine was just like taking off your pants to fart. It was unnecessary.

Even Lai Wenming was shaken, because he was the person in charge of the medical tests, and he really didn't find any problems.

Just because of the concerns and speculations of a few people like him, the soldiers were treated so coldly. It was too harsh.

So far, the strong quarantine policy has been abolished.

Humanity has missed its last chance.

But Chen Feng believes that even if he continues to implement it, there is actually not much difference.

As long as humans do not realize the nature of ZS bacteria, and still blindly believe in his own judgment, and do not thoroughly sterilize the planet's surface with ultra-high temperature before returning to the planet, and completely destroy the planet's ecology, they are destined to be infected.

In the world, every drink and bite seems to have its own subtleties.

At the end of March in 2542, an elite warrior named Pavlov Ponomarenko got a short day off.

He dragged his tired body back home and had a brief reunion with his long-lost wife Nikolai Ponomarenko.

Pavlov's gene awakening degree was as high as 35.71%, but his beloved wife's was only 31.58%.

Pavlov is a galactic human, but Nikolai is far from that.

Theoretically, the possibility of the two getting the crystal of love is very low, and the success rate of adopting the traditional reproduction model is less than one percent.

So although Pavlov loves his wife deeply, as an excellent warrior with an iron will and a lofty sense of responsibility, he is not very interested in the traditional model of reproduction, thinking it is a waste of time. Although

Nikolai is not very awake, his IQ is amazing, and he is also a busy physicist.

The couple treat each other with respect most of the time, just silently guarding each other, leaving the matter of reproduction to the fully intelligent pairing of artificial intelligence, trying their luck, hoping that it will always succeed.

Even if they occasionally need to, they would rather take a break from their work and use holographic simulation technology to communicate with each other. Anyway, the feeling is the same.

But this time, the two had a romantic candlelight dinner together, and the song "Happiness to the Nth Power" was played as a seasoning during dinner. The

emotional intensity of both parties was suddenly raised, and they couldn't help themselves.

After one night, Pavlov went to the battlefield again and was killed in a large-scale encounter three months later.

In early February 2543, Sergei Ponomarenko was successfully born.

In July 2558, when Sergei, 15 years old, had just shown his amazing intelligence and learning ability, becoming the youngest person in the past century to obtain a doctorate in both physics and engineering, the war situation underwent an irreversible and overwhelming change.

During this month, Sergei, who was only 15 years old, wearing a full protective isolation suit, personally killed his respected mentor, the director of the Institute of High Energy Physics, Ou Mengfeng.

The day before the incident broke out, Ou Mengfeng had just met his great-grandson who had returned from the front.

He stood outside the gate of the Institute of High Energy Physics and forced Sergei to see him off for the last time.

Sergei, who was still a teenager, was forced to take over the post of director of the Institute of High Energy Physics.
