In the next two hundred years, the technological level of human civilization developed very quickly.

Although the technological development was slightly distorted due to the blockade of the solar system and the inability of humans to enter the outside world, humans have achieved the ultimate in the exploration of internal resources.

The last time Chen Feng came here, it was not until the last moment that he realized that the solar system was compressed and the speed of light was less than 300,000 kilometers per second.

But this time the situation was completely different. After building the Dyson membrane, humans had already realized the changes in the speed of light and space.

But this did not cause any trouble to the development of human technology as Chen Feng had worried.

The adaptability of earthlings is much stronger than Chen Feng imagined.

Zhong Lei once advised Chen Feng not to treat civilization as a little baby that does not need to be carefully cared for.

The current situation perfectly verifies Zhong Lei's words.

Scientists naturally adapted to the new cosmic physical rules under the changed speed of light without much trouble.

Now everyone knows that humans are indeed struggling in the chessboard drawn by the invaders.

Since the rules of the universe have been changed, humans have to develop technology under the distorted rules of the other side. Then, in theory, no matter how hard humans try, they cannot jump out of the shackles created by the invaders. If

it were not for the catastrophe brought by the S bacteria that hammered the resilience of mankind, perhaps everyone would collapse when they realized this.

But no, humans are still tottering forward in silence.

The s bacteria almost destroyed the entire civilization, but somehow left precious spiritual wealth to mankind.

Even if it is a desperate struggle, humans want to break the invaders' teeth.

Chen Feng felt this kind of spirit of the world and was intoxicated by it.

After reading history, it was already four o'clock in the morning. Chen Feng stretched his back and lay down on the bed.

But he did not fall asleep immediately, but raised his pillow and analyzed all the information he had collected so far.

The value of history is not for entertainment, but to explore useful information and objective laws from what has happened in the past, and provide a theoretical basis for making future plans.

Sergei's judgment is completely correct.

The birth of s bacteria was a remedial action taken by the invaders after they found that the mind penetration of "Song of the World" had failed.

But perhaps the invaders did not expect that such a vicious plan would fail under the united resistance of mankind.

Humanity did pay a painful price, but in the end, instead of being defeated, it developed even better.

This shows that although the invaders are incredibly powerful, they can also make a bad move that is not so wonderful.

Chen Feng's confidence was greatly encouraged.

In his heart, the invaders are no longer so powerful that they are hopeless.

The enemy did not make a good move with the s bacteria, and then exposed another weakness of the opponent.

The five hundred years between the arrival of the solar system barrier and the arrival of the invader's battleship should be fixed.

Before their warships arrive, they can only rely on remote control of the solar system barrier to play some "tricks".

Their actions are not unlimited, there must be a limit.

Otherwise, the S bacteria should be stronger.

Or, they don't have to go to so much trouble, "Song of the World" and S bacteria.

There is a paradox hidden in this that is not easy to be noticed.

The solar system barrier is so terrifying that it appears without any signs, and it can even compress space. The technological content is completely unreasonable.

The invaders themselves are extremely afraid of real contact with humans.

And watching the S bacteria strategy fail, humans become stronger, they did not speed up to shorten the time to reach the destination.

Time moves forward.

Theoretically, the most likely scenario is that the invader's detector captured a certain traveler, analyzed its data, and sent the data back to the other side's base camp.

The base camp responded by deploying a galaxy-level blockade barrier and sending battleships here.

The blockade barrier achieved instantaneous travel across ultra-long distances, arrived in 2500, and began to capture and blockade the solar system.

However, the battleship was left behind and could not erase the 500-year navigation time difference.

This is too unreasonable.

A civilization with such a technological level as the solar system barrier should not be so easily restricted by space distance.

Its main combat units should have opened a wormhole outside the solar system long ago and used superluminal flight, almost arriving at the same time as the barrier.

The only reason for this is that there is a huge generation gap between the technological content of the solar barrier and the speed of the enemy's warships.

Chen Feng came to a conclusion.

The solar barrier is incompatible with the invaders' own technological system!

This is not something that belongs to their civilization.

The barrier was produced and manufactured by another more powerful and advanced civilization.

This situation is roughly equivalent to when Europeans landed in America, intervened in the war between two indigenous tribes, and provided muskets and artillery to one of the indigenous tribes in exchange for food and building materials.

Chen Feng was excited again.

This is another huge weakness of the invaders!

Well, write it down in the little notebook.

His thoughts returned to another matter.

In the past, the invaders used mind infiltration to hide a kind of ultra-fine particles in the commanders' hobby carriers.

At the critical moment when the war was about to begin, they activated these ultra-fine particles and transformed these hobby carriers into antimatter bombs, instantly destroying the huge human fleet.

Later, Chen Feng asked Ou Qinglan to give these ultra-fine particles a name.

The two named it the particle involved.

This time the commanders' hobby is gone.

On the one hand, "Songs from the World Outside" has failed, and on the other hand, Chen Feng believes that there should be no particle involved bombs this time.

Because the action of interfering with the destiny of mankind through remote control of the solar system barrier requires a certain kind of energy.

This energy is limited.

Either "Songs from the World Outside" can be played and the particle involved bomb can be hidden beside the commander.

Or, S bacteria can be cultivated and catalyzed.

They can only do one of the two things!

The third important message was analyzed by him.

Chen Feng's deduction continued to deepen.

Where did the previous particle involved bombs come from?

How does the solar system barrier silently interfere with and affect the rules of basic particles on the earth and form particles involved?

Why are the particles not distributed evenly around the world and in different regions, but concentrated around battleship captains and many military commanders?

What is the connection between the process of constructing particles and the hobbies of these commanders?

When a person likes something or sees something, what changes will occur in the thinking mode of the brain?

After the spiritual level of a person is first penetrated and disturbed by thoughts, will there be a special quantum fluctuation that is born with the thinking movement of the brain, and converges on the hobby carrier, and finally catalyzes the generation of particles?

If I understand this whole process, can I reverse its principle, also create particles, and find a way to activate them?

Then can't we learn from Gusu Murong Fu and give him a taste of his own medicine?

In the midst of his hazy deductions, Chen Feng finally fell into a deep sleep due to exhaustion.

This time, he slept particularly soundly.

Because even when he entered a deep sleep, he was still doing deductions in his dreams that seemed impossible to get answers.

After this time, since his physical advantage no longer existed, Chen Feng was unwilling to sink into mediocrity and had to use his brain desperately.

It made his brain, which had become a little rusty due to his reliance on physical advantages, particularly active.

Therefore, human potential is always unlimited.

If you don't push yourself, you don't know how good your brain is.

"Ahem."

The next morning, Chen Feng woke up in a confinement room.

Although it is called a confinement room, his treatment is actually quite good.

One bedroom, one living room and one bathroom, a standard apartment layout, with all the daily necessities available, and no deductions on food and drink expenses.

The treatment is even better than when he was self-isolating at home a thousand years ago to avoid infectious diseases. At least he doesn't have to cook and wash dishes by himself.

After a hearty breakfast, Chen Feng entered the holographic space a few minutes early, waiting to listen to Teacher Ou's teachings.

There was still some time before class, so he opened the information system and browsed around casually.

This time he chose to read some contemporary current affairs.

As he read, he felt emotional again.

This era is really good. It

is full of vitality.

Facing the end of the world, it is particularly peaceful, but people work harder than in the past.

Technology is advancing rapidly, and new technologies can be seen being developed every day.

The decision-making level is also completely humanized.

Every citizen has the right to vote for any major decision.

As long as you want to participate in the decision-making, you can open your personal intelligent terminal anytime and anywhere to participate in the areas you are interested in or understand, and then vote.

Even Chen Feng, who is in solitary confinement, can do it.

Regardless of whether you are poor or rich, everyone is treated equally in voting.

It is no longer the thinking of some people that makes decisions for the entire society, but the collective wisdom composed of the thinking of all human beings.

Moreover, due to the popularization of the education system, the whole people are highly educated. This collective wisdom is not only not ignorant, but also reveals a mysterious wisdom and calmness.

The world government has transformed into a purely service-oriented government.

There are many coincidences in the birth of this wonderful pattern.

Chen Feng was not sure whether the next time humans would face S bacteria, or whether such a situation could be formed.

However, even if he only came here to experience it once, it would be worth his life.

"Cough cough."

His throat was inexplicably itchy, and he coughed twice.

At this moment, the image of Ou Qinglan appeared.

She frowned slightly, "Are you catching a cold?"

Chen Feng shook his head, "No." "

That's strange, many people only catch a cold once in their life. With your physique that can pass the volunteer soldier assessment, you shouldn't catch a cold. Can't you see that you are so weak?"

Chen Feng smiled awkwardly, "No way, don't talk nonsense. I'm super strong, okay? Thinking about the past..."

"What past? What past can you have, a last-place repeater recruit like you?" Ou Qinglan spoke sarcastically to him while using his instructor's authority to retrieve the record of what he did yesterday.

"Tsk, tsk, I thought. You are really capable, reading these historical materials until four in the morning, you deserve it! How did you grow up like this? What did you do for so many years when you were a child? Forget it. I won't talk about you anymore."

Ou Qinglan was a little angry at him for not fighting.

Maybe he felt that he was unworthy of his face and name.

"To make a long story short, you won't have the chance to feel the loving beating from me in person during your class today. I have something to do, so I can only entertain you with a data simulation of my image."

Chen Feng smiled, "It's okay, I'll try my best. Go and do your thing, you don't even have to notify me."

"No, it's not necessary." Ou Qinglan grinned devilishly, "Because I set your simulated instructor to the most stringent Nun Extermination mode. Good luck, bye!"

Chen Feng: "wtf!"
