Hanju did not disappoint him.

It's a megacity indeed.

After a week of simple circles, Chen Feng initially estimated that the population size of Hanzhou should be more than 300 million.

Shizhong District covers an area of nearly 4,000 square kilometers.

The layout of the building is not dense, nor is it very tall.

With the exception of collapsed high-rise buildings, most of the buildings are no more than a kilometer high.

However, the size of the building is very large, and it often covers an area of tens or hundreds of acres.

Chen Feng looked at it briefly and was overjoyed.

He saw a lot of destroyed machinery in these large buildings, and even found a supercomputing center.

Chen Feng speculated that Hanzhou played the role of an industrial manufacturing center and a science center this time, which is exactly what he wanted.

He first found the guest apartment according to the direction in his memory and lived in it.

Finding this apartment is quite simple, thousands of years have passed, and the layout of the apartment is no different from the past.

I think it has become a place of interest again, and it has been preserved as it is.

Of course, the reinforced concrete buildings of the XXI century will certainly not survive for so many years.

Now there is still this style, and the building materials must have been changed.

Unlike other large buildings, there is hardly any futuristic technology in the guest apartment, almost exactly the same as when he settled, the original taste, even the electrical appliances are antiques that he is used to.

It is precisely because there are not many products of postmodern technology in the cultural heritage community that the degree of destruction of the guest apartments is very low.

After simply settling down, he swept the city with ease.

When dealing with big cities, you can't just wander around like you do with small cities.

He first spent the whole day dividing the Hanzhou ruins into four areas: scientific research area, industrial area, accommodation area, and commercial area, and at the same time divided these four areas into three different exploration priorities according to the degree of damage.

That night, he walked leisurely to the eastern suburbs scientific research area with a teacup in hand.

He had noticed that there was a huge metal cylinder rising into the sky in the scientific research area in the eastern suburbs.

The diameter of the cylinder is more than 300 meters, the height is more than 4,000 meters, and the shell is an all-metal structure, with dozens of sections.

This is a very large optical telescope.

He didn't expect to see such an ancient principle in this era, and it was still built on the earth, which was quite surprising to him.

What's even more surprising is that although the central control brain has been destroyed, the main structure of the telescope is still intact, and even the lenses inside are intact.

In the middle of the night, technician Chen, who was fresh on the road and specialized in making explosions, preliminarily repaired the function of the telescope and successfully transferred the picture to a messy projector.

He finally saw the world beyond the stars through his telescope.

There is an extra large band of light between the orbits of Neptune and Uranus.

The bands of light revolve like planets orbiting the sun.

From time to time, there are arcs flickering above the light belt, and almost every arc contains enough energy for thunderstorms on the earth to last for three days and three nights.

Chen Feng continued to magnify the magnification of the optical telescope, and could distinguish that the components of the light band were rag-like objects stacked one after another.

It is from these "rags" that the arc is generated, then collides and flows and is excited.

Chen Feng knew what it was, the "corpse" of Dyson membrane torn apart.

He was pleased.

Humans in this timeline have accomplished the feat of creating the Dyson membrane 2,500 years ago.

Although it is now a human remains, the torn Dyson membrane has also been reunited to form a giant "solar ring".

But traces of its existence at least show that human efforts have not been in vain.

If everything is irretrievable, thousands or even hundreds of millions of years later, when other new races come to the solar system and see the remains of these Dyson membranes, they may think of it as a natural spectacle of a new universe.

These civilizations will cry out like that.

"Ah, this is a great life-like structure, a purely natural stellar ring with genetic information. How incredible the universe is! ”

But at this time, in Chen Feng's heart, there was only a thousand words of emotion left.

Since the Dyson membrane has been artificially destroyed, then the human civilization in the solar system should really not be spared this time.

He had also fantasized before that maybe there were humans on other planets such as Mars.

The corpse of Dyson Membrane destroyed his illusions.

Chen Feng shrugged his shoulders and said to himself, "Forget it." ”

But he finally came to another conclusion.

The emergence of Dyson membrane is of great significance to mankind, representing that mankind's use of photosynthesis has completely reached the second stage, and there is almost an inexhaustible source of energy and basic materials in the solar system.

Referring to the technological level of Dyson membrane and the productivity it can bring, then mankind must have built countless large-scale transstellar spacecraft 2,500 years ago.

There will only be more Endeavor expeditions rushing out this time, and there should not be only two expeditionary colonies that can successfully reach their destination.

Otherwise, it's not logical.

So there must be a lot of human colonies in Orion's arm!

Thinking of this, Chen Feng became happy again, and scanned the night sky with an optical telescope, and began to imagine in his heart that in the galaxies in Orion's arm, maybe there were also newborn humans looking in the direction of the earth.

"How would it feel if people who went out knew that there was someone looking at them from their home planet at this time? Move? Happy? Send a ship with curvature flight to pick me up right away? ”

No one has spoken, Chen Feng is afraid that he will lose his language ability, and he has developed the habit of breaking thoughts when he has nothing to do.

And then......

He screamed.

Yes, he thought of a new solution.

The intelligent equipment has been completely destroyed, and it is almost impossible and infinitely difficult to cobble together a ship with astronautical capabilities from the ruins of the earth alone.

Even if he can solve the power problem with biological batteries, he will not be able to solve the computing needs of the curvature engine, let alone have navigation ability and space shield.

A new question arises, how do I send a signal to the people in the colony that there is still one more person on Earth?

Ten minutes later, he shook his head in frustration.

Getting used to quantum networks, he overlooked one thing.

The limit of the speed of light.

Even if he did build a large radio beacon on Earth, it would take four years to reach the colony at the speed of light.

But a year later, the prismatic fleet of the compound eye civilization will arrive at Orion's Arm.

Chen Feng did not know what the direction of this war would be, and whether he would be able to hold out for three years.

Well, it doesn't really matter.

Human colonies can pick up his signals, and so can compound eyes.

Then, with the warship performance of the Compound Eye, it is almost impossible for the rescue ship that he summoned back first, but only the enemy.

Chen Feng shook his head with a wry smile, and drank the tea in the cup in another sip.

Forget it, let's continue to excavate the history of the earth according to the original plan, and try to pick up garbage and piece together or repair ships by yourself.

If you have the opportunity, you can also try to build an auxiliary brain by yourself, then the problem of navigation and shield will be solved.

This thing seems to be a fantasy, but in fact, there is a thin line of separation.

As long as he can find a palm-sized brain chip that is still intact, and then find two stable biological quantum structures that are used as database storage carriers, he can really put something together with his now more and more mature assembly technology.

Back in the room, Chen Feng made himself another cup of strong tea and wrote a diary again.

This time, he didn't write trivial things in his diary, but only finalized two core policies for himself.

First, eat everything in Hanju City within a month and dig deep into the history.

Second, pick up more garbage and try to build ships with artificial intelligence.

And when he lived, seven more days passed.

In those seven days, he collected more than 10,000 parts and caused hundreds of explosions.

But he is indeed getting more and more proficient, and he doesn't need to look at the nameplate, but only needs to take a cursory look at the shape of the part to know which is the voltage transformer capacitor, which is the energy flow stabilizer, and which is the gravitational signal transmitter.

He even assembled an old-fashioned crawler-style engineering vehicle, and installed a gravitational wave detector on the construction vehicle that can scan a radius of 500 meters.

It's a little sad to say it.

He found the complete frame of the gravitational wave detector in a children's toy that resembled the form of the Galactic Warball's ultimate battle armor.

What was a child's science toy about 500 years ago has become his right-hand man.

The reason it wasn't destroyed was probably because it was just a toy.

All in all, his garbage picking efficiency has improved dramatically.

He also improved the function of the quark meter, and finally it can automatically identify objects with antimatter battery characteristics, and stop the quark replication in time to prevent the short circuit from exploding.

His personal collection is also growing, and he can make more than a dozen different flavors at each meal, and his quality of life has been greatly improved.

Everything is changing for the better.

But there are also hidden dangers, Chen Feng found that he was more and more inseparable from the tea with the leftovers of Qiubailu fried by himself.

Obviously, the taste is very ordinary, but the tea always does not leave the hand, and it is uncomfortable if you don't drink it for an hour.

And the buzzing sounds in his head from time to time are becoming more and more frequent, and the volume is still increasing.

Sometimes he would wake him up in the middle of the night, and his first reaction when he woke up was to take a bite.

There is no doubt that something is wrong with my state.

This is an addiction, and the addiction is big, just like the ship commanders who rolled the hoop and played the Gentry card back then.

But Chen Feng was not alarmed.

Anyway, people will always die, and after death, these negative states will be eliminated, so why be afraid?

He is even actively increasing his intake.

He wanted to know what the extra messages his brain was trying to say.

The essence of the biological battery of tea should be the same as the special parts in the body of other animals, but the degree is not as strong, so this message should not only be directed at him, but also those animals.

Understanding the nature of the message may lead to new answers.

At this time, he hadn't reacted yet, every time he drank tea, the biocurrent in his brain would be slightly strengthened, and his logical thinking would enter a highly active state, making his reasoning ability climb steadily, and at the same time, he was quietly suppressing his emotions.

This effect is exactly the same as "Song of the World".

He could have been immune, but because of drinking tea, it went directly into the body, and with the absorption of polyphenol organics by the digestive system, it directly entered the brain, and he could no longer withstand it.

As for these messages, they are the signals that are summarized by his intuition through the invisible link between his highly active logical thinking and the wisdom of the universe.

This is the second time he has developed a sense of connection to the wisdom of the universe, and it is very long-lasting, stronger than the last time he was chased and bombarded by countless particle bombs, the brain quantum storm has a stronger connection to the universe.

As the message continued to grow, he began to understand what was inside.

It's an order.

The command had a very broad direction, but he did not understand the specific content.

Before he knew it, more than half a month had passed, and he had finally completed a new piece of equipment.

A string energy level underlying gene analysis detector.

Without artificial intelligence, the detector can only give a long list of massive information in the display that ordinary people will get dizzy at a glance.

But it doesn't matter, he can see with the naked eye and parse it with the human brain.

Chen Feng first measured his genetic arousal, and then, based on experience, compared the key parts of the genetic information listed with the detailed tables he had seen in the past, and then was shocked.

41.77%！

He didn't even know what was going on, his genetic arousal level quietly exceeded 40%, and he went a long way forward.

It's no wonder that lately I feel like my brain is getting better and better, and I'm analyzing data faster and faster.

He scratched his head, and could only attribute the reason to drinking tea.

Later, he analyzed the genetic information of special things such as snake gall bladder and wolf teeth.

In order to make an accurate comparison, he also went out hunting again, and then got a whole fresh cobra viper, and compared the snake gall with other conventional parts at the same time.

After three days of difficult analysis, Chen Feng discovered something strange.

The snake gallbladder, which has the properties of an antimatter battery, has a special piece of cause information compared to the rest of the snake's body.

The information felt familiar to him, and he relied on the memory of pictures to complete the comparison.

The similarity with the latent fragment in S bacteria was as high as 44%, and the similarity with the fragment responsible for the formation of group intelligence in Z bacteria was as high as 56%.

The case has been solved.

In this timeline, humanity was defeated at the hands of a new type of bacterium that fused the abilities of S and Z.

Chen Feng named it ZS bacteria.

He also knew the general content of the order.

The order requires carriers of bacteria to search for and destroy humans, as well as to erase the traces that could become key to human history, including energy cores, intelligence cores, and historical materials.

On the surface, there is no essential difference between ZS bacteria and the previous two bacteria.

Chen Feng can even roughly calculate the direction of the war, lurking, controlling, developing carriers, and setting off wars.

The steps should be the same as the Mass Extinction Holocaust in the eighth timeline, but one change is unprecedented.

Z bacteria do not invade the human body and control the human mind.

ZS bacteria can.

Z bacteria can only lurk in animals, and the war set off is also a race war with a very clear camp.

However, ZS bacteria can not only invade animals, but also definitely differentiate some humans.

Then in this war, normal human beings have to face two enemies at the same time.

Controlled by ZS bacteria, but fully aware of human technology, the same family, and mutant animals with powerful special abilities.

The technological level of mankind becoming stronger does not bring an intuitive advantage in war.

Because ZS bacteria people also get this knowledge.

As the war deepens, ordinary human beings also can't get rid of the possibility of being invaded by ZS bacteria, and their own people will only become fewer and fewer, but there are more and more enemies, and there will be no end, so this war is almost doomed from the beginning.

After sorting out his thoughts, Chen Feng sighed.

He had already guessed.

With the self-ability of compound eye civilization, it may not be possible to creatively invent a new strain that combines the characteristics of Z bacteria and S bacteria.

Therefore, this thing must also be the product of a super-level civilization that has insight into the physiological characteristics of the earthlings.

In 2,500 years, the compound eye civilization made a preliminary observation of the current situation of mankind through the solar dome, and had a strong sense of crisis, and asked for help.

Chen Feng found a sad logical dilemma.

Humanity cannot win without doing its best to advance technology.

But if you continue to advance science and technology and succeed in stealing it for another 500 years, the compound eye will come up with a desperate killer like ZS bacteria.

What to do?

The first 500 years were low-key, and then broke out after 2500?

But does it work?

As long as the solar system is shrouded by the solar dome, no matter how it erupts later, it will not be able to break through the solar dome in a day, and it can only be locked up and waiting for death.

Let the colony's technology explode, and the solar system native pretends to be stupid and cute?

This is also a solution.

But Chen Feng really didn't know how to achieve this kind of precise control across 500 years, and it was too embarrassing.

In addition, with the ability of the compound eye to instantly transfer the solar dome, even if the plan is successful, as soon as the fleet of the compound eye civilization arrives in the solar system, it finds that the strong enemy is on another planet, and the backhand moves the solar dome to the galaxy with a higher level of technology to implement the blockade, and the result is basically the same.

No matter how opportunistic he tried, he could not solve the problem fundamentally.

After thinking about it, Chen Feng made a decision.

Don't think about shortcuts, let's use stupid methods.

I believe that there is no way to be endless, no matter how invincible ZS bacteria is in theory, as long as you can eat it thoroughly in advance, it is not that you can't prepare targeted restraint methods.

Because the total amount of energy that can be mobilized in the solar dome is limited, ZS bacteria, which combines the advantages of two bacteria, must have some kind of defect.

What human civilization will have to fight in 2,500 years is not essentially any visible enemy, but the energy that can be mobilized in the solar dome.

Humanity has to mobilize the power of the whole race to fight these energies.

Since the energy is limited, the power of the means indirectly exerted by the compound eye civilization will definitely have an extreme.

As long as human abilities are strong beyond a certain range, no matter what means can be used, the problem will be solved.

Or, every time a new means appears, your own side will crack it in a targeted manner, and then continue to add new confrontation methods to your bag, so that one day you can squeeze out the imagination of the other party, and there is also a chance to usher in a head-on battle again.

After straightening out this line of thought, Chen Feng's long-term confusion in his heart was swept away, and he regained his vitality and continued to work overtime.

These days, he has slightly enhanced the performance of his floating motorcycle, which can reach a top speed of 1,000 kilometers per hour, and has transformed the motorcycle into an enclosed cockpit that no longer needs to block the wind with his face.

When he swept the ruins of Hanzhou almost to the ground, he once again enlarged the scope of exploration.

In the mountainous area 3,000 kilometers away from Hanzhou, he discovered a huge radio telescope, which is beyond the imagination of mankind in the 21 st century.

This proves once again that before mastering the complete means of quantum entanglement exploration, electromagnetic waves are still the main carrier of the largest amount of information in the universe, and future generations still attach importance to it.

The reflector of the radio telescope was badly damaged and scattered to the ground.

But it didn't bother him.

Chen Feng personally got started and drove the construction machinery to grind piece by piece.

Before he knew it, another two months passed, and he used the repaired radio telescope to identify a key piece of information.

The dome of the sun is gone.

This day is February 12, 3020.

At the beginning of spring, it is finally a good time to pick tea.
