Since then, the war has entered its second major phase.

From 2540 to 2558, the war has lasted for a full eighteen years.

In the early days, humans had strictly implemented isolation measures.

But after 2542, the policy changed.

Although space life assisted by the quantum network has a considerable degree of social isolation, most people always have a habitual fear of germs and actively reduce social interaction as much as possible, but this has lasted for more than ten years, and more than ten years is still too long.

In these long ten years, the ZS bacteria has quietly lurked and spread and has never stopped.

Today, the number of people infected has reached a point where it is difficult to reverse the situation, at least more than one-third of the total population.

Relying on powerful quantum intelligence, the infected can be quickly traced back to the source and clearly retrieved.

The highest intelligence, Stars, took less than 0.1 second to accurately locate each suspected infected person and notify everyone's smart auxiliary watch.

But it's too late, it's meaningless.

The insidiousness and cruelty of the Z bacteria are self-evident, and the ZS bacteria are even more desperate.

Lurking, infiltration, enhanced infiltration, and then the big outbreak in July 2558, all in one go.

This is a routine that humans are very familiar with, but the object of effectiveness has changed from animals to themselves, and the threat level caused is completely different.

ZS humans completely retain their original memories and have human IQs. Even their personalities will not change much, but the angles they think about problems have changed.

No matter which angle they made the decision from, the final destination changed from maintaining the survival of mankind to eradicating mankind from the solar system.

The front-line fighters were almost wiped out, completely assimilated, their values ​​​​were tampered with, and their thinking was controlled.

Other major fields, especially the middle and high-level in the field of science, also suffered heavy losses.

At this point, mankind's technological advantage has disappeared, and the war has completely tilted to the enemy side that controls bacteria.

Chen Feng slowly "turned" the following historical materials page by page.

Although he only gave Xiaowei orders with his mind to turn pages and switch videos, Chen Feng still felt that he had done his best.

He had already known the outline from Sergei's projection and had already filled his mind with many tragic plots.

He thought he had prepared himself mentally and should have been numb to the constant destruction.

But now that he really watched it carefully, he realized that even though he had participated in countless wars of destruction, his mental preparation was actually very pale and powerless. When he really saw it, he still felt heartbroken.

Losing step by step until destruction.

In just eight words, the entire history from 2558 to 2589 can be summarized.

But in this process, it is filled with countless flesh-and-blood details.

The defeat is divided into many stages.

The first stage occurred when ZS humans tore off their disguises and turned their butcher knives against their former compatriots, and Fanxing gave the results of the infected population.

All those who had come into contact with ZS humans and were listed as infected by Fanxing, but whose ZS bacteria had not yet multiplied to a sufficient scale and who could still maintain independent thinking, faced the same choice in an instant.

Life or death?

Most people's choices were the same as Ou Mengfeng's, who ordered Sergei to kill himself.

It's just that the speed of making decisions was slightly different.

Ou Mengfeng was decisive. As soon as he received the news, he consulted Lai Wenming through personal connections.

At that time, Ou Mengfeng asked Lai Wenming, "Xiao Lai, is there a way to treat this bacteria?"

Lai Wenming: "Not yet."

"How long will it take to develop it?"

"I don't know."

"You have been studying control bacteria for many years, right?"

"Yes, from 2540 to now, never slacking off."

"Then how long do you think we can stay awake?"

Lai Wenming: "I don't know. Control bacteria are different from the past. It has wisdom. It can lurk in the human body for more than ten years without any movement, but it may also actively increase its activity, multiply rapidly and scale up. Therefore, your thoughts may be taken over at any time."

"Can we recover by destroying the body and rebuilding it?"

"No, the main place where the control bacteria attach is actually our brain. It is deeply integrated with our neurons in an unprecedented way. The brain cannot be rebuilt."

Ou Mengfeng nodded painfully, tears streaming down his face.

After a long time, he first said to Lai Wenming, "I'm sorry, Xiao Lai, I should support you."

Lai Wenming: "It's okay, Teacher Ou, you have your opinion."

The two hung up the phone, and Ou Mengfeng called all the infected people in the Institute of High Energy Physics to the square, and then faced the front more than ten meters away, holding the evaporative particle gun, the bewildered Sergei and many security guards The staff said loudly: "From today on, Sergey, you are the dean of the Institute of High Energy Physics! Sergey, you have unprecedented talent, you can become the master of the past and the future! I have high hopes for you. I believe that our death will not be the end, you can and must continue to go on! Shoot! Kill us! Don't hesitate, shoot!"

Bang bang bang!

Some people struggled in hesitation and pain for two or three days, and after seeing the ferocity and brutality of ZS humans and more and more people marked as infected suddenly lost control, these hesitant people collapsed and made decisions one after another.

Some people walked out of the space in the space station and floated in the universe.

Some people jumped into the quark decomposition machine.

Someone drove a spaceship into the sun.

Another person said goodbye to his family in the quantum network with a high explosive bomb before exploding.

…

The first stage was named "Farewell" by Sergei.

The second stage was "Choice".

In order to make up for the lack of combat power caused by the betrayal of a large number of Galaxy Rangers, the young Sergei, who had just started out, crossed several academic levels and joined forces with Lai Wenming to establish the Gene Rapid Breakthrough Plan.

The essence of the Breakthrough Plan was slightly different from the Colonized War God and the Magic War. It only absorbed part of the Z bacteria and the Colonized Magic War system left by Chen Feng, and then supplemented it with the knowledge derived from biological giants such as Lai Wenming. It chose to focus more on the exploration of human potential rather than turning into other species of non-magic warfare.

It took only three days for the Breakthrough Plan to be completed. About 20 million people were transformed in different space stations, and the number of survivors was 4 million.

The awakening level of these four million survivors quickly exceeded 35%, and they put on the new Galaxy Armor with improved intelligent algorithms by Sergei and rushed to the battlefield.

The third stage is "adhesion".

In this stage, the war between humans and ZS bacteria has been fought from space to the ground.

Humans once took back the earth briefly, but because they needed to maintain ultra-high-level protective measures on the earth, it was very inconvenient to move, so humans left the earth again.

During the entire confrontation, although the productivity mastered by ZS humans in the early stage was not as good as that of humans, the main combat units were only ZS humans who were originally Galaxy Warriors, and a large number of mutant animals.

But the reproductive capacity of mutant animals is too amazing, and all planets in the solar system are sources of soldiers.

These numerous and extremely difficult to completely kill soldiers made up for the disadvantage of ZS humans in the early stage.

The battles on space stations and warships also greatly reduced the military strength of humans.

Although humans reacted quickly, ZS humans' latent actions were clustered. On the basis of one-third of the total population infected, two-fifths of human ships rebelled as a whole.

Major space stations were also severely damaged.

Humans regained control of about two-thirds of the space stations, and another one-sixth of the space stations suffered devastating damage. Another one-sixth of the space stations were the result of the rebellion of the remaining ZS humans after humans were eliminated.

In addition, hundreds of millions of small aircraft took off secretly, wreaked havoc on the space station, and then flew away.

These changes allowed ZS humans to successfully survive the early stages.

Since then, the war has entered the fourth stage, "powerlessness."

With the rapid reproduction and evolution of ZS bacteria mutants, biological spaceships based on giant mutant marine animals appeared.

Some large birds and suture mutants grew into various ZS human individual equipment and various combined war machines.

The ZS bacteria seemed to be born with the technology of growing battleships that Chen Feng had been seeking but could not obtain. It just needed some years of sedimentation and digestion and absorption of human achievements.

After that, human beings' space advantage disappeared in an instant.

In this stage of the confrontation, humans felt a deep sense of powerlessness.

No matter how tirelessly humans fought, they could not match the regeneration ability of ZS bacteria.

No matter how quickly Sergei and others improved their equipment, the ZS bacteria's troops could always quickly stabilize the situation after a brief panic, and in turn absorb new technologies from humans.

ZS humans also showed extremely high quality in tactics and strategy.

On the front battlefield, the ZS human fleet can compete with the human forces controlled by the stars in terms of fine control ability. On

small battlefields, ZS humans have even more unique tricks, and each of them is fearless and brave, and their fighting style stands out as a loser.

As the war progressed, on another battlefield, Lai Wenming and Sergei and others never stopped researching.

At that time, the division of labor between Lai Wenming and Sergei was very clear.

Sergei was responsible for improving the performance of human warfare weapons, while Lai Wenming was responsible for trying to develop control bacteria vaccines, special medicines that could cure control bacteria infections, and injectable drugs for rapid treatment and ability improvement on various battlefields. Lai Wenming

's workload was both large and difficult. The latter two items were okay. Although they were difficult, progress could always be seen from time to time.

Only the first two items really tortured both his body and his spirit.

The feeling of having nothing to gain no matter how hard you try is really too painful.

When Lai Wenming was most desperate, he cried and roared while holding his head in his hands during a private meeting with Sergei.

"Why can there be such creatures in the universe? Why? This is unfair! Why should the enemy who can create such creatures be our enemy? We don't even have the ability to cause the slightest harm to them. The gap between us and them is countless times greater than that between ants and elephants. Why is this!"

Lai Wenming stared with a pair of cloudy old eyes, grabbed Sergei's shoulders and kept asking.

Sergei thought for a long time, "Probably, because we are human. The sage Chen Feng must have thought about this problem, but I think he must have never been confused. He just accepted this fate, and then tried to move forward little by little, that's all."

In 2589, the highest scientific research space station of mankind fell in the middle of the Great Plains of Australia.

Humanity was defeated, ZS bacteria turned into fireworks and dissipated in space, and the solar dome disappeared.

The history of human civilization in the solar system in the ninth timeline came to an abrupt end here.

Chen Feng closed the book silently.

He slapped himself hard.

This time, humans actually had the opportunity to avoid the tragedy, but made many wrong decisions.

Chen Feng also knew where he went wrong.

But in the final analysis, the fault was all his.

He thought he had already prepared himself mentally and could withstand the end of the solar system that he had created with his own hands.

But the sense of regret, loss and guilt always lingered.

He looked up at the ceiling of the reading room and murmured to himself.

"I'm sorry, everyone. I will do better next time. Definitely."

Above the ceiling, the spirits of the heroes who died in the 26th century seemed to still be floating, quietly looking at him, waiting for him in another timeline.

Of course, there might not be a next time.

So many people went out this time, and countless colonies have already been built in the Orion Arm.

So Chen Feng believes that humans have a certain chance of winning.

He also hopes so.

But he still has to observe and make a choice.

Reason tells him that as long as there is a one in a billion chance, he will still fight for it.

But in this way, perhaps the timeline will end, and the direct descendants of the disappeared solar civilization will never come back.

Perhaps this may very well include the child's mother.

He has this anxiety.

But he can't give up another group of people for one group of people.

Chen Feng missed the child's mother very much, and of course he couldn't bear to leave the child's mother.

But he also knew that if the mother knew that he had given up a free universe for her,

she would definitely not forgive me, right?

She was the one who loved to sacrifice herself the most.

So, Chen Feng told himself, I will still strive for everything possible, but I will also face failure calmly.
