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

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

Z bacteria are everywhere on various planets, settlements, space stations, and even in human warships.

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

No matter how big or small the animal is, almost no one is spared.

The time has come.

In 2558, the catastrophe came suddenly.

The more hidden it is when it lurks, the more ferocious it will be when it erupts.

This time, humanity is facing a huge army of extinct animals that are everywhere and too numerous to count.

The war started both as expected and without warning.

In the context of the 26th century, this was a war that was as threatening as Chen Feng facing a spherical battleship.

It was intense from the beginning, and humanity was pushed to the brink of extinction in an instant.

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

There are ten thousand ways for a powerful civilization to destroy a low-level civilization.

They don't even have to come in person, they just need an insignificant individual in the civilization to press a button or flip a switch from a distance.

The world of low-level civilizations has been shrouded in endless darkness and is 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 was difficult for him to control his emotions.

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

He would not blame the programmer named Panda.

He was blaming himself.

In order to increase the possibility of hatching the stars again and reduce the potential threat of the stars, he once again raised the human artificial intelligence development capabilities in advance, and at the same time made a lot of foolproof indirect impact equipment.

Judging from the situation in the 31st century, he did it, but he subconsciously ignored another problem.

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

In the previous timeline, Sergei's encryption algorithm did last until the 31st century.

But in this timeline, the technological background of the times is changing, the computer system is upgrading, and the level of top programmers is also changing.

The once invincible algorithm is no longer invincible, and it is only natural that it is cracked in advance.

It is reasonable for Hua Zhongyun and other civilization leaders at that time to make such a decision.

If he were in that position, he would not be able to resist the temptation to prepare the S bacteria vaccine in advance.

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

I was paralyzed by the pleasure of achieving phased results again and again, and my vigilance was reduced.

Alas.

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

Although humans have been preparing for war for 58 years, it is far from enough.

This is not a mistake, it is helpless.

After the S bacteria failed to show up, even the smartest scientists could not give specific suggestions.

Everyone knows that they should put aside the war in five hundred years and solve the current problem first.

But what is the problem?

How will the invaders present themselves?

No one knows until the outbreak actually occurs.

So we can only consider all directions from all angles.

With infectious diseases as the main prevention and control target, vigorously develop medicine and biology.

With possible thought infiltration as the secondary prevention and control target, strengthen the popularization of "Morrowind" among the people, observe the psychological state of the people at any time, and prevent logical thinking.

With conventional space warfare ideas as the long-term planning, large battleships and heavy space weapons are appropriately developed.

Appropriate rather than full development is constrained by the energy production limit of Dyson Cloud and the first generation of solar wings, and the shortage of materials in the context of the failure to master the mass-energy conversion technology. After

all, no matter how large the war tools produced now are, they are estimated to be just scrap copper and iron in 500 years, and a lot of energy will be wasted for recycling and reuse, and some non-recyclable rare resources will be used less and less.

Moreover, from 2468 to 2500, in the 32 years, in order to produce nearly 100,000 large expedition colony ships, humans consumed a lot of relatively rare types of naturally generated metal resources in the solar system, and wanted to mass-produce top-level equipment, but they were also powerless.

Finally, since wars cannot happen among humans anymore, it is better to develop technology first and produce experimental equipment that is destined to be eliminated, rather than the current militarism, to provide technical guidance for continuous improvement.

At the same time, equip some basic military equipment with appropriate strength, and then wait for the right time to decisively increase production capacity.

This is the best policy.

The current potential crisis is very dangerous, and the doomsday of destruction in five hundred years is even more dangerous. There must always be a balance.

In short, considering many factors, the enemy is too strong and too cunning, and too fierce when it breaks out, and humans only have conventional military equipment. Humans who are not well prepared quickly fall into a dilemma of being unable to resist.

The Extinct Animal Army not only possesses terrible killing power, but is also well-organized and well-commanded. They have been preparing for so many years and have already quietly completed a careful layout and formulated a grand and precise war plan.

The powerful Extinct Animals have a combat power close to that of the single-soldier Qinglong Armor used by Chen Feng.

At that time, humans had equipment similar to the Qinglong Armor that Chen Feng had worn, but it was not equipped on a large scale.

Humans have technology, but lack both materials and time, and are unable to complete the manufacture of large quantities of equipment.

Everything is too late.

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

Six months later, major military bases fell one after another.

The remaining fleets are basically useless.

If the warships had not escaped to outer space quickly enough, the extinct animals would not have been able to master the ability to survive in space like the dragonfly fighters, and this last bit of human resistance would have been gone.

The battleships were constantly guarded by the powerful top-level extinct animals with the ability to fly in the air. They could not fall into the atmosphere and could only launch long-range attacks from outside the space. However, the distance was too far and the attenuation in the atmosphere meant that the results of the war onboard equipment were not satisfactory.

Large space-based weapons should have been very effective. They could have swept the ground by simply turning the muzzle. However, the commanders of the extinct animals had already paid attention to these potential threats at the beginning, so there was no hope.

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

Humans had no protection from large war machines.

The high-powered and high-yield weapons were also destroyed in the first round of attacks, so it was only a luxury to die together.

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

Not enough, this is far from enough.

The defense forces of major cities can withstand the first round of impact and temporarily repel it, which is the limit.

But this can only prolong their survival for a while.

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

Reproductive ability.

Take mice as an example.

After 21 days of pregnancy, each litter has at least five or six babies, and at most more than ten.

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

This extreme condition is roughly like this: no natural enemies, sufficient food, and no plague or disease.

The current situation meets two of the conditions. There are no natural enemies, and these mice infected with Z bacteria will not get sick.

But there is one thing that does not meet the requirements: food.

The mice that have been transformed into extinct animals are generally as big as wolfhounds. Given the huge base number of mice, it is likely that even if all the meat on the earth is eaten up, it would not be enough.

But this situation did not occur. These extinct animals look large in size, but their appetite has not increased significantly. They eat as much as they did before, as if the energy supporting their terrifying movement ability and strange attack ability came out of thin air.

The scholars at the time were puzzled, and they finally figured it out. 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 produce energy, humans still haven't completely cracked it until today in the 31st century, and can only speculate that it may be related to antimatter.

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

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

But after the oxygen content in the Earth's atmosphere continued to decline, the residents of the Earth could not go out and had difficulty moving in the wild.

Plants began to grow wildly.

In 2568, ten years after the extinction of animals swept the solar system, the oxygen content in the Earth's atmosphere dropped to 15%.

The situation of mankind has become more difficult.

The extinct animals, on the other hand, are like fish in water, and have adapted very well to the new low-oxygen environment.

The killing continues.

During this period, humans sent negotiators in the hope of reaching a settlement.

But it was useless.

The extinct animals, which were forcibly endowed with logical intelligence, seemed to have burst out all the hatred of being enslaved and slaughtered by humans for tens of thousands of years since entering the slave society.

It is also possible that the logic of the actions of the extinct animals is simply determined by the bacteria.

The bacteria are not real life, but weapons.

Weapons and hunting objects do not have the idea of ​​coexistence.

Weapons only know endless killing, and will not stop until death.

Just like the executioner's scalpel, how can they sympathize with the innocent people who are about to become the souls under the knife?

The knife does not understand human language.

As the negotiators were torn apart, the possibility of peace talks was completely eliminated.

It was in 2568 that humans, who had given up their last illusions, finally succeeded in changing their thinking and found a way to win this war.

We have no battleships, no space-based weapons, no missiles, and no large beam cannons.

Our guns have been destroyed.

Our ammunition depot is about to be emptied.

Even the machetes in our hands have become damaged.

We only have two things now, our own bodies, and the will that will never bow to fate.

Without weapons, we use our bodies as weapons!

This time, Lai Wenming and Sergei Bonomarenko, two geniuses who rose to prominence only 20 years apart, stood together and found a way to improve humans in a similar way to the extinct animals. Give them a taste of their own medicine.   This trick has always been Chen Feng's specialty.

But   Chen Feng did not rely mainly on his intelligence, but on theft and fraud that crossed the timeline.   Lai Wenming and Sergei relied purely on their amazing wisdom that overwhelmed the times and crossed the years!

Chen Feng had imagined many times what kind of sparks would be produced if these two people who were born so close to each other could join hands with all their strength.

Now he knows.

From 2546 to 2568, Lai Wenming conducted in-depth research on Z bacteria for 22 years.

He understood the essence of Z bacteria, read the wisdom of Z bacteria, and understood the principle of Z bacteria transforming organisms. He also extracted human-adapted Z bacteria from slugs of extinct animal species that can avoid attacks from the human immune system and coexist with the human body.

Sergei designed a transformation method that uses metal pipes in the human body to simulate the internal circulation of extinct animals.

The combination of these two geniuses can allow humans to use Z bacteria to gain terrifying single-player combat power.

No need for armor, people are armor.

This plan is named - Extinction Colonization Suit.

People who use the Extinction Colonization Suit are called Colonization War Gods.

There are also differences in personal strength after becoming Colonization War Gods. The strongest can compete with Chen Feng who wore the Azure Dragon Armor back then, and the average ones are just ordinary Azure Dragon Warriors.

The difference in strength has little to do with age and physical strength, but only with the degree of compatibility between the person's own genetic information and the genetic information of Z bacteria, and only with how much Z bacteria his brain can carry.

The Extinction Colonization Suit has extremely strong side effects and is irreversible.

The Colonial War God will completely lose his mind and wisdom, and become a beast-like existence, retaining only the killing instinct driven by hatred, and can only maintain a stable life form for less than a month at most.

After the stabilization period, no matter how strong the Colonial War God is, it will quickly collapse and no bones will be left.

Moreover, even in a stable state, the Colonial War God will still feel the endless pain every moment, as if he is being fried in a pan.

This is undoubtedly a method of drinking a dove to quench thirst. How many people accept the colonization will definitely die.

But no matter what, humans have no way out and can only fight hard.

After the first old man accepted the colonization suit and ignored the humans around him, he turned into a mad demon with red eyes and rushed out of the city defense line, rushed into the army of extinct animals and killed everyone for half an hour before being besieged and torn into pieces.

Sergei and Lai Wen knew that the plan was successful.

The warships in space rushed down against the siege of the flying extinct animals.

At the cost of losing 80% of the warships, the fleet successfully took away the transformation plan, the design and manufacturing drawings of the transformation instrument, and the human-adapted Z bacteria samples extracted from the extinct slugs and artificially cultivated.

The remnant warships eventually transported these important strategic resources to every planet and settlement in the solar system that was still able to fight.

At that time, the total human population had dropped to less than 13 billion, of which 2.6 billion were over 100 years old.

The elderly waved goodbye to their children and grandchildren one after another and stepped into the colonial transformation machine.

I don’t know which old man who likes to listen to music played his favorite "Bath of Fire" on his portable device.

Others followed suit, playing "Self-Ignition", or intoxicated in "Across the Stars" or "God of War".
