Hanzhou did not disappoint him.

This is indeed a huge city.

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

Shizhong District 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 buildings are no more than a thousand meters tall.

However, the buildings are very large, often covering 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 would play the role of an industrial manufacturing center and a scientific center this time, which was exactly what he wanted.

He first found the guest apartment according to the direction in his memory and stayed there.

Finding this apartment is quite easy. Thousands of years have passed, but the layout of the apartment is no different from the past.

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

Of course, the reinforced concrete buildings of the 21st century will certainly not survive for so many years.

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

Unlike other large buildings, there is almost no future technology in Ke Lai's apartment. It is almost exactly the same as when he settled there. It is authentic and even the electrical appliances are antiques that he is used to.

It is probably because there are not many products of post-modern technology in the heritage community that the degree of damage to the Ke Lai Apartment was very low.

After simply settling down, he then 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 a whole day dividing the Hanzhou ruins into four large areas: scientific research area, industrial area, accommodation area and commercial area. At the same time, he divided these four large areas into three different exploration areas according to the degree of damage.

Priority level.

That night, he leisurely came to the Eastern Suburb Scientific Research Zone, which had the highest priority, holding a tea cup in hand.

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

The cylinder is more than 300 meters in diameter and more than 4,000 meters high. The outer shell is an all-metal structure with dozens of sections in total.

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. He was quite surprised.

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

After struggling for most of the night, Technician Chen, who was new to the field and specialized in making explosions, initially restored the function of the telescope and successfully transferred the picture to a messy assembled projector.

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

There is a huge band of light between the orbits of Neptune and Uranus.

The bands of light rotate like planets orbiting the sun.

There are arcs flashing above the light belt from time to time. The energy contained in almost every arc is enough to cause a thunderstorm on Earth to last for three days and three nights.

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

The arc is generated from these "rags", and then collides, flows and is excited.

Chen Feng knew what this was, the "corpse" of a Dyson membrane that had been torn to pieces.

He was very pleased.

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

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

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

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

These civilizations will cry out.

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

But at this time, in Chen Feng's heart, there was only emotion that could not be expressed in a thousand words.

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

He had also imagined before that there might be humans on Mars and other planets.

The remains of the Dyson membrane destroyed his illusions.

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

But he finally came to another conclusion.

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

Considering the technological level of the Dyson membrane and the productivity it can bring, then this time humans must have built countless large-scale inter-stellar spacecraft 2,500 years ago.

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

Otherwise this is illogical.

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

When he thought of this, Chen Feng became happy again, happily scanning the night sky with his optical telescope, and began to imagine in his mind that in the star systems in Orion's arms, there might be newborn humans looking in the direction of the earth.

"If the people who walked out knew that there was a person looking at them from the home planet at this time, how would they feel? Moved? Happy? Send a ship with the warp flight capability to pick me up immediately?"

No one spoke all the time, and Chen Feng was afraid that he would lose his language skills and develop the habit of talking about nothing.

Then……

He screamed.

Yes, he thought of a new solution.

Intelligent equipment has been completely destroyed. It is almost impossible and infinitely difficult to piece together a ship with aerospace capabilities from the ruins of the earth by just one person.

Even if it can solve the power problem by relying on biological batteries, it cannot solve the computing needs of the curvature engine, let alone have navigation capabilities and aerospace shields.

A new question arises, how can I send a signal to the people in the colony to let them know that there is still a person on the earth?

Ten minutes later, he shook his head in frustration.

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

Limitation on the speed of light.

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

But one year later, the Compound Eye Civilization's prism fleet will arrive at the Orion Arm.

Chen Feng didn't know what the direction of this war would be, or whether it could last three years.

Well, actually that doesn't matter.

The human colonies could receive his signal, and so could the compound-eyed ones.

So with the performance of the compound-eyed warships, it is almost impossible for the ones he summons back first to be human rescue ships, but only enemies.

Chen Feng smiled bitterly and shook his head, then drank the tea in the cup in one 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 rubbish.

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

This may seem like a fantasy, but it's actually just a thin line.

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

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

This time he did not write down trivial matters in his diary, but only finalized two core policies for himself.

First, learn everything about Hanzhou City in one month and explore the history in depth.

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

While he was here, another seven days passed.

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

But he is indeed becoming more and more proficient. He doesn't even need to read the nameplate. He only needs to take a cursory look at the appearance of the parts to know which is the variable voltage capacitor, which is the energy flow stabilizer, and which is the gravity signal transmitter.

He even assembled an old tracked engineering vehicle and installed a gravitational wave detector with a scanning range of 500 meters on the engineering vehicle.

It's a bit sad to say it.

He is the complete frame of the gravitational wave detector found in a children's toy that resembles the form of Galaxy Senmaru's ultimate suit.

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

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

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

He also improved the function of the quark meter and was finally able to automatically identify objects with the characteristics of antimatter batteries and terminate quark replication in time to prevent short-circuit explosions.

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

Everything is changing for the better.

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

Although the taste is very ordinary, I always keep the tea in my hands. If I don't drink it for an hour, I will feel uncomfortable all over.

Moreover, the buzzing sound in his head became more and more frequent, and the volume continued to increase.

Sometimes it would wake him up in the middle of the night, and his first reaction after waking up would be to take a sip.
To be continued...
