Hanzhou did not disappoint him.

It is indeed a megacity.

After a simple circle around, Chen Feng initially estimated that Hanzhou's population should have been over 300 million.

The downtown area covers an area of ​​nearly 4,000 square kilometers.

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

Except for the collapsed high-rise residential buildings, most of the buildings are no more than a kilometer high.

However, the buildings are very large, often covering tens or hundreds of acres.

Chen Feng took a quick look and was overjoyed.

He saw a lot of damaged machines 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 scientific center this time, which was exactly what he wanted.

He first found the Ke Lai Apartment according to the direction in his memory and stayed there.

It was quite easy to find this apartment. After a thousand years, the layout of the apartment is exactly the same as before.

I guess this place has become a historical site and has been preserved as it is.

Of course, the reinforced concrete buildings of the 21st century cannot be preserved for so many years.

It still has this style now, and the building materials must have changed.

Unlike other large buildings, there is almost no future technology in the Kelai Apartment. It is almost exactly the same as when he settled here. Even the electrical appliances are antiques that he is used to.

Perhaps it is because there are not many products of post-modern technology in the cultural relics community that the degree of damage to the Kelai Apartment is very low.

After settling down simply, he went around the city with ease.

When dealing with a big city, you can't just wander around like you would a small city.

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

That night, he came to the highest priority Dongjiao Scientific Research Area with a teacup in his hand.

He had noticed before that there was a huge metal cylinder rising into the sky in the Dongjiao Scientific Research Area.

The cylinder has a diameter of more than 300 meters and a height of more than 4,000 meters. The outer shell is a full metal structure with dozens of sections.

This is an oversized optical telescope.

He didn't expect that in this era, he could still see such an ancient thing, and it was built on the earth. He was quite surprised.

What was even more surprising was that, although the central control computer was destroyed, the main structure of the telescope was still intact, even the lens inside was intact.

After struggling for most of the night, Chen, a technician who had just started to specialize in manufacturing explosions, initially repaired the function of the telescope and successfully transferred the image to a messy projector.

He finally saw the world outside the starry sky through the telescope.

A huge light belt appeared between the orbits of Neptune and Uranus.

The light belt rotated like a planet orbiting the sun.

There were arcs flashing above the light belt from time to time, and the energy contained in almost every arc was enough to keep the thunderstorm on Earth going for three days and three nights.

Chen Feng continued to increase the magnification of the optical telescope and could distinguish that the components of the light band were pieces of rags piled together.

The arc was generated from these "rags", then collided, flowed and excited.

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

He was relieved.

The humans in this timeline completed the feat of creating the Dyson membrane 2,500 years ago.

Although it has now become a relic, the torn Dyson membrane has also reassembled to form a huge "solar ring".

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

If everything is irreversible, when other new species come to the solar system tens of millions or hundreds of millions of years later and see the remains of these Dyson membranes, they may regard them as a new wonder of the universe.

These civilizations will shout like this.

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

But at this moment, in Chen Feng's heart, there is only a thousand words that can't express the emotion.

Since the Dyson membrane has been destroyed by human beings, then this time the human civilization in the solar system should really have no chance of survival.

He had imagined before that there might still be humans on other planets such as Mars.

The remains of the Dyson membrane destroyed his fantasy.

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

But he came to another conclusion.

The emergence of the Dyson membrane is of great significance to mankind. It means that mankind has completely reached the second stage of photosynthesis and has almost inexhaustible energy and basic materials in the solar system.

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

There will be more expeditions rushing out this time, and there should not be only two expedition colony ships that can successfully reach the destination.

Otherwise, it is not logical.

So there must be many human colonies in the Orion Arm!

When he thought of this, Chen Feng became happy again. He happily scanned the night sky with an optical telescope and began to imagine that in the galaxies in the Orion Arm, there might be new humans looking in the direction of the Earth.

"If the people who go out know that there is someone on the mother planet looking at them at this moment, how will they feel? Touched? Happy? Send a ship with curvature flight capability to pick me up immediately?"

No one spoke, and Chen Feng was afraid that he had lost his ability to speak, so he developed the habit of mumbling whenever he had nothing to do.

And then...

he screamed.

Yes, he had thought of a new solution.

Smart devices were destroyed so thoroughly that it was almost impossible and infinitely difficult to piece together a ship with space capabilities from the ruins of the earth by himself.

Even if he could rely on biobatteries to solve the power problem, he could not solve the computing requirements of the curvature engine, let alone have navigation capabilities and space shields.

A new problem arose. How can I send signals to the people in the colony to let them know that there is still a person on Earth?

Ten minutes later, he shook his head in frustration.

After getting used to the quantum network, he overlooked one thing.

The limit of the speed of light.

Even if he really built a large radio signal transmitting tower on Earth, it would take at least four years for the signal to reach the colony at the speed of light.

But one year later, the frigate fleet of the Compound Eyes civilization will arrive at the Orion Arm.

Chen Feng didn't know how this war would go, or whether it could last for three years.

Well, actually that didn't matter.

The human colonies could receive his signals, and the Compound Eyes could certainly receive them.

Then with the performance of the Compound Eyes' warships, it was almost impossible that the ships he summoned back first were human rescue ships, but only enemies.

Chen Feng smiled bitterly and shook his head, and drank the tea in the cup in another gulp.

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

If there is a chance, we can also try to assemble an auxiliary intelligent computer by ourselves, so that the problems of navigation and shields will be solved.

This may seem like a fantasy, but it is actually just a step away.

As long as he can find a palm-sized smart chip that is still intact, and two stable biological quantum structures that serve as database storage carriers, with his increasingly mature assembly skills, he can really piece together something.

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

This time he did not write trivial things in his diary, but only decided on two core guidelines for himself.

First, to thoroughly understand everything in Hanzhou City within a month and delve into history.

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

He stayed there for another seven days.

During these seven days, he collected more than 10,000 parts in total and created hundreds of explosions.

But he did become more and more skilled. He didn't even need to look at the nameplate. He only needed to take a quick look at the appearance of the parts to know which one was a transformer capacitor, which one was a flow stabilizer, and which one was a gravitational signal transmitter.

He even assembled an old-fashioned tracked engineering vehicle and installed a gravitational wave detector with a scanning range of 500 meters on it. It's

a bit sad to say it.

He found the complete frame of the gravitational wave detector in a children's toy that looked like the Galaxy War Maru Ultimate Armor.

This thing was probably just a child's science toy five hundred years ago, but now it has become his right-hand man.

The reason why it was not destroyed may be because it was just a toy.

In short, his efficiency in picking up garbage has greatly improved.

He also improved the function of the quark meter, and finally it could automatically identify objects with antimatter battery characteristics, terminate quark replication in time, and prevent short circuit explosion.

His personal collection is also increasing, and he can make more than ten different flavors for every meal, which greatly improves the quality of life.

Everything is changing for the better.

But there are hidden dangers. Chen Feng found that he was increasingly inseparable from the Qiu Bailu leftover tea that he made by himself.

Obviously, the taste is very ordinary, but he always can't put down the tea. He will feel uncomfortable if he doesn't drink it for an hour.

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

Sometimes it will wake him up in the middle of the night, and the first reaction after waking up is to get a sip.

There is no doubt that there is something wrong with his condition.

This is an addiction, and a strong one, just like those ship commanders who played Gwent in the past.

But Chen Feng was not panicked.

After all, everyone will die, and these negative conditions will disappear after death, so why should he be afraid?

He even took the initiative to increase his intake.

He wanted to know what these extra messages captured by his brain meant.

The biobattery nature of tea should be the same as the special parts in other animals, but the degree is not as strong, so this message should not only be for him, but also for those animals.

Understanding the nature of the message may give new answers.

At this time, he hadn't reacted yet. Every time he drank tea, the bioelectric current in his brain would be slightly strengthened, and his logical thinking would enter a highly active state, allowing his reasoning ability to rise steadily, while also silently suppressing his emotions.

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

He could have been immune, but because of drinking tea, it directly entered his body, and along with the absorption of polyphenol organic matter by the digestive system, it directly entered his brain, and he couldn't hold it anymore.

As for these messages, they were signals that he intuitively concluded after his highly active logical thinking and the invisible connection with the wisdom of the universe.

This was the second time he had a sense of connection with the wisdom of the universe, and it was very long-lasting, and the connection between the quantum storm in his brain and the universe was stronger than the last time he was hunted and bombarded by countless particle bombs.

As the message continued to deepen, he gradually understood the meaning behind it.

It was an order.

The order had a very broad direction, but he didn't understand the specific content yet.

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

A string energy level basic gene analysis detector.

Without artificial intelligence, the detector can only give a long list of massive information on the display that would make ordinary people dizzy after just one glance.

But it doesn't matter, he can see it with his naked eyes and analyze it with his brain.

Chen Feng first tested his own gene awakening, and then based on his experience, he compared the key parts of the listed genetic information bit by bit with the detailed table he had seen in the past, and then he was shocked.

He didn't know what happened, his gene awakening level quietly broke through 40%, and went a long way forward.

No wonder he feels that his brain is getting better and better recently, and he can analyze data faster and faster.

He kept scratching his head and could only attribute the reason to the tea drinking.

He then analyzed the genetic information of special things such as snake gall and wolf fangs.

In order to accurately compare, he went out hunting again and got a whole fresh spectacled viper, and compared the snake gall with other regular parts.

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

The snake gall, which has the properties of an antimatter battery, has an additional special genetic information compared to other parts of the snake.

He felt that this information was familiar, and relied on picture memory to complete the comparison.

The similarity with the segment responsible for lurking in the S bacteria is as high as 44%, and the similarity with the segment responsible for forming collective intelligence in the Z bacteria is as high as 56%.

The case was solved.

In this timeline, humans were defeated by a new type of bacteria that combined the abilities of S bacteria and Z bacteria.

Chen Feng named it ZS bacteria.

He also knew the general content of the order.

The order requires the bacterial carrier to search for and destroy humans, as well as erase key traces that can become human history, including energy cores, intelligence cores and historical materials.

On the surface, ZS bacteria are essentially no different from the previous two bacteria.

Chen Feng can even roughly deduce the direction of the war, lurking, controlling, developing carriers, and starting a war.

Its steps should be no different from the great catastrophe in the eighth timeline, but there is one unprecedented change.

Z bacteria cannot invade the human body and control human thinking.

ZS bacteria can.

Z bacteria can only lurk in animals, and the wars they start are also race wars with very clear camps.

But ZS bacteria can not only invade animals, but also certainly differentiate some humans.

So in this war, normal humans have to face two enemies at the same time.

Their own race whose minds are controlled by ZS bacteria but fully understand human technology, and mutant animals with powerful special abilities.

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

Because ZS bacteria people also get this knowledge.

As the war progresses, ordinary humans will also be unable to escape the possibility of being invaded by ZS bacteria. The number of our own people will only decrease, while the number of enemies will increase, and there will be no end. Therefore, the outcome of this war was almost doomed from the beginning.

After sorting out his thoughts, Chen Feng sighed.

He had already guessed it.

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

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

In 2500, the compound eye civilization initially observed the current situation of mankind through the solar dome, developed a strong sense of crisis, and sought help from above.

Chen Feng discovered a sad logical dilemma.

If humans don't push technology to the utmost, they won't be able to win.

But if they continue to push technology and successfully steal another 500 years, the compound eyes will take out the ZS bacteria, a despairing killer.

What to do?

Keep a low profile for the first 500 years and wait for the outbreak to happen 2500 years later?

But will it work?

As long as the solar system is covered by the solar dome, no matter how much it breaks out later, it will still be locked up and wait for death if it can't break through the solar dome.

Let the technology of the colonies explode, and the solar system natives pretend to be stupid and cute?

This is also a way.

But Chen Feng really doesn't know how to achieve such precise control across 500 years. It's too difficult.

In addition, with the ability of the compound eyes to instantly transfer the solar dome, even if the plan of pretending to be stupid succeeds, once the fleet of the compound eyes civilization arrives in the solar system and finds that the powerful enemy is on another planet, it will move the solar dome to a galaxy with a higher level of technology to implement a blockade, and the result will be basically the same.

No matter how he thinks of opportunistic methods, he cannot solve the problem fundamentally.

After thinking about it, Chen Feng made a decision.

Don't think about shortcuts, just use stupid methods.

Believe that there is always a way out. No matter how invincible the ZS bacteria is in theory, as long as you can understand it in advance, it is not impossible to prepare a targeted restraint method.

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

In essence, what human civilization will have to fight in 2500 is not any visible enemy, but the energy that can be mobilized in the solar dome.

Humans must use the power of the entire race to fight against these energies.

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

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

Or, every time a new method appears, he can crack it specifically and keep adding new countermeasures to his bag. Then one day he can drain the opponent's imagination and have the opportunity to face off again.

After sorting out this idea, Chen Feng's long-term confusion was swept away, and he cheered up and continued to work overtime.

These days he slightly enhanced the performance of the hoverbike, the maximum speed of the motorcycle can reach 1,000 kilometers per hour, and he also transformed the motorcycle into a closed cockpit, so he no longer needs to use his face to block the wind. When he

had almost finished sweeping the Hanzhou ruins, he expanded the scope of exploration again.

He discovered a huge radio telescope in a mountainous area 3,000 kilometers away from Hanzhou, which was larger than the imagination of mankind in the 21st century.

This once again proves 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 great importance to it.

The reflector of the radio telescope was severely damaged and scattered on the ground.

But this did not bother him.

Chen Feng personally took action and drove the engineering machinery to grind it piece by piece.

Unknowingly, two months passed, and he used the repaired radio telescope to determine a key piece of information.

The solar dome disappeared.

This day is February 12, 3020.

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