More than 90% of the animals in the entire solar system have basically been infiltrated.

In the earth's atmosphere, soil, and oceans, bacteria have become ubiquitous.

Z-bacteria are already everywhere on various planets, settlements, space stations, and even human battleships.

Ants, mosquitoes, locusts, flies, mice, snails, slugs, leeches, sea shells, earthworms, lions, tigers, elephants, whales...

No matter whether they are big or small animals, almost no one is spared.

The time has come.

In 2558, great changes came suddenly.

How concealed it is when dormant, how ferocious it is when it explodes.

What humans have to face this time is a huge army of extinct animals that are everywhere and in such huge numbers that they cannot be counted.

The war was both expected and started without warning.

In the context of the twenty-sixth century, this is a war with a threat level not inferior to that of Chen Feng when facing a spherical battleship.

It was white-hot from the beginning, and mankind was instantly pushed to the edge of destruction.

In history books, this war is named the Great Extinction.

If a powerful civilization wants to destroy inferior civilizations, there are ten thousand ways.

You don't even need to come in person, you just need an insignificant individual in this civilization to press a button or flip a switch from a distance.

The world of lower civilizations has been shrouded in endless darkness and under the threat of doomsday.

Before opening this thick war history, Chen Feng's fingers trembled slightly.

He knew that many people would die.

It is difficult for him to control his mood.

He tried his best to avoid this situation, but it still happened.

He doesn't blame the programmer named Panda.

He is blaming himself.

In order to increase the possibility of re-incubating the stars, and to reduce the potential threats of the stars, he once again enhanced human artificial intelligence development capabilities in advance, and also made a lot of complete indirect impact equipment.

Judging from the situation in the thirty-first century, he did indeed do it, but he subconsciously ignored another issue.

This was an honest mistake, but you can't have your cake and eat it too.

In the previous timeline, Sergei's encryption algorithm was indeed maintained until the thirty-first century.

But in this timeline, the technological background of the times is changing, computer systems are being upgraded, and the level of top programmers is also changing.

The once invincible algorithm is no longer invincible, and it is natural for it to be cracked in advance.

It is reasonable for civilized leaders like Hua Zhongyun to make that kind of decision.

To put it another way, if he were in that position, he would still be unable to resist the temptation to prepare the S-bacteria vaccine in advance.

Chen Feng sighed, after all, this was still my mistake.

I was numbed by the pleasure of achieving staged results again and again, and my vigilance dropped.

well.

At that time, humans had not yet mastered the Dyson membrane, nor had they obtained mass-energy conversion technology.

Although mankind has been preparing intensively for 58 years, it is far from enough.

This is not a mistake, this is inevitable.

Even the brightest scientists are unable to give concrete advice when S. bacteria fail to make an appointment.

Everyone knows that it is important to put aside the war five hundred years from now and solve the immediate problem first.

But what exactly is the problem?

How will the intruder's methods be presented?

No one knows until it actually breaks out.

Therefore, we can only consider all directions from all directions and angles.

Focus on infectious diseases as the main targets of prevention and treatment, and vigorously develop medicine and biology.

Taking the possible infiltration of thinking as the secondary prevention and control target, we should strengthen the popularization of "Morrowind" among the people, observe the people's psychological state at any time, and prevent logical thinking.

Use conventional space warfare ideas as a long-term plan and appropriately develop large warships and heavy space weapons.

Appropriate development instead of full development is due to the energy output limitations of Dyson Cloud and the first-generation solar light wings, and the shortage of materials in the context of failure to master mass-to-energy conversion technology.

After all, no matter how huge the war tools produced now are, they will probably be just scrap copper and iron in five hundred years. A lot of energy will have to be wasted for recycling and reuse, and some of the rare resources that cannot be recycled will be used less.

Furthermore, in the 32 years from 2468 to 2500, in order to produce nearly 100,000 large expedition colonial ships, humans consumed a lot of relatively rare types of naturally occurring metal resources in the solar system. They wanted to mass-produce top-notch equipment.

There is also a sense of helplessness.

Finally, there is no possibility of another war within human beings anyway. Rather than resorting to militarism now, it is definitely better to develop technology first and only experimentally produce phased equipment that is destined to be eliminated to provide technical guidance for continuous improvement.

At the same time, install some basic armaments of appropriate strength, and then wait for the right time to decisively increase production capacity.

This is the best policy.

The current latent crisis is very dangerous, and the doomsday crisis five hundred years from now is even more dangerous. There must always be a balance.

In short, taking into account various factors, the enemy was too strong and cunning, too ferocious when it broke out, and mankind only provided conventional armaments. The ill-prepared mankind quickly fell into a predicament unable to resist.

The army of extinct animals not only possesses terrifying lethality, but is also well-organized and commanded. It has been preparing for so many years and has quietly completed a thorough layout and formulated a grand and precise war plan.

The powerful extinct animal has a combat power close to that of the individual Qinglong Armor used by Chen Feng.

At that time, humans had equipment that was close to the Qinglong Armor that Chen Feng once wore, but it was not deployed on a large scale.

Humans have technology, but they are short of materials and time, and there is no time to complete a large amount of equipment manufacturing.

It's too late.

In just one month, more than 90% of humanity's warships, all large space stations, and all arsenals were lost.

Half a year later, major garrison bases fell one after another.

The remaining fleet is essentially useless.

If the warships hadn't escaped into outer space fast enough, extinct animals would not have been able to master the ability to survive in space like the dragonfly fighter jets, and humanity's last resistance would have been wiped out.

The battleship is constantly guarded by powerful top-level extinct animals with the ability to fly in the air. It cannot fall into the atmosphere and can only launch long-range attacks in outer space. However, the distance is too far and the attenuation of the atmosphere means that the battle results caused by the ship-borne equipment are really

Unsatisfactory.

Originally, large-scale space-based weapons should be very effective. Just turn the muzzle to carry out sweeping strikes on the ground. However, the commanders of Exterminate Animals focused on these potential threats from the beginning, and there was no hope for them.

After that, the people who stayed on the surface of the planet began to fall into a great crisis.

Humanity has no protection from large war machines.

Weapons with high power and high yield were also completely destroyed in the first round of offensive, and even their destruction was a luxury.

Humanity can only rely on individual equipment to barely resist, coupled with a small number of vehicle-mounted missiles and beam cannons.

Not enough, this is far from enough.

The defense forces in major cities were able to withstand the first round of attacks and briefly repel them, which was as far as they could go.

But this is just a way to survive for a while.

There is a very obvious difference between most animals and humans.

Reproductive ability.

Take mice for example.

After 21 days of pregnancy, each fetus can range from five to six to more than ten.

Under extreme conditions, a pair of male and female mice can reproduce a huge population of 5,000 individuals a year.

The limiting conditions are approximately this: no natural enemies, sufficient food, and no plague or disease.

The current situation is consistent with two of them. Since there are no natural enemies, these mice infected with Z bacteria will not get sick.

But there is one thing that doesn't fit in, the food.

Rats transformed into extinct animals can generally reach the size of wolves and dogs. With the huge number of rats, it may not be enough to eat all the meat on the earth.

But this situation did not happen. These extinct animals looked very big, but their food intake did not increase significantly. They still eat as much as they used to eat, as if the energy to support their terrifying movement abilities and strange attack abilities came out of thin air.

Scholars at the time were puzzled by the explanation, and they finally figured it out later.

The main source of energy for animals infected with Z bacteria is no longer their digestive system, but the Z bacteria colonies in their brains.

As for how Z bacteria generate energy, until today in the thirty-first century, humans have still not completely cracked it, and can only speculate that it may be related to antimatter.

As time goes by, the number of extinct animals becomes more and more overwhelming.

Needless to say, the situation on other planets is that even after a short period of a hundred years or a long period of two hundred years of transformation, the air in the wild is still thin, and residents can only live normally in settlements.
