Pudong has a population of 20 million, corroded from high in the sky, and the square skyscrapers and kilometers are as dazzling as the disassembled computer circuit boards. Every day when the sun rises, the subway and buses carry a large number of humanitarian jobs from all over the country, and the 9-to-5 life begins.

Raw materials and primary industrial products from all over the world are assembled and produced here, and experimental data from all over the country are collected, summarized and calculated here, and finally a large number of design schemes are transmitted to various places through a convenient information network.

This is the model of a high-tech city, where the output of various physical industrial products is not the highest, but the initial prototypes of many mass-produced industrial products are designed here, experimented, and then made from science and technology experimental companies, and then the data and prototypes are distributed to the national production line for mass production.

Due to industrial experiments, unlike mass production, the air here is good.

Since the actual usage data is summarized, there is no need to visit the front-line industrial production department, so the office building is equipped with air conditioning, so it seems that the working conditions are good.

But people often only see the benefits and ignore the giving.

But here is the center of intensive mental work. Imaginative design, there is a lot of diligent work, in accordance with the rules of reality, let creativity lead to the accumulation of real technology, creativity and realistic technology compromise. Finally, a feasible physical product is formed. The high pace of the big city, the rules and regulations in the middle of the box, and the busyness that burns out brain power all the time are the normal life of the citizens of this city.

Chongming District, located at the mouth of the Yangtze River, is an ivory tower to enjoy this technological era. But the ordinary life of a big city like a pigeon cage is not as good as these naïve children imagined.

The quiet and distant culture is not seen at all in the modern metropolis, and everyone's time is very tight, so the advertising and sales are as exaggerated and fast-paced as possible.

On a huge electronic screen hanging from the building, a team of teenage girls in miniskirts quickly cheered and said something, and then the end of the ad turned into a zoomed-in image of a sanitary napkin and the pink text "Princess Tips." ”

Only PSAs play slowly, with a huge ad screen showing lush jungle, then trees withering, rows of smoky chimneys, and finally giant solar photovoltaic panels. Several members of the public took turns saying, "Protect the planet and let the sun be full of love." ”

The public service announcement was made to promote a recent campaign in Pudong, where the government was recently funding the installation of solar panels on the roofs of buildings.

This activity to protect the earth has also affected Chongming City, for example, Linyuan Academy has to install a large solar panel on the building.

Lu An, who was wearing gray volunteer clothing, wiped the sweat from his forehead and pulled the straw hat that was common in the fields. There are many women's sunhats in the city, but there are no golden straw hats, which are purchased online by Lu An, with this old farmer-style straw hat, which has caused many classmates to laugh, because this image is too earthy old hats. However, those classmates who are also under the sun now can't help but show envious eyes. The exaggerated brim of the straw hat is perfect to avoid direct sunlight on the face.

Looking at the young man in the corner with a sad face in the sun, Lu An whispered in his heart: "People in the era of peace." ”

The phrase "people in the era of peace" in the war years where Meng was in place meant to die to save face and suffer crimes. It means that you want grace not temperature.

Just as people in this world don't understand why Lu An would wear such a hat that is so earthy and does not match the style of painting of young and handsome face. Lu An also didn't understand why people in this world would rather wait in the sun to peel off their skins than have a straw hat on their heads.

Meng's era was the era of war, and in the era of war, bullets, gun barrels and even the wreckage of tanks and planes that were rare in the era of peace were everywhere, and microwave ovens, hair dryers, and induction cookers became luxury items. Instant noodles, quick-heating rice, this kind of peacetime junk food was everyone's hard currency during the war years, and even the instant noodle basins that were eaten were left to be used as containers to collect rainwater. No one collects this as garbage, but as a valuable item.

No matter what kind of war, it is destroyed, and destruction means a huge shortage of materials. While operating advanced armaments, he nibbled on yesterday's leftover MSG rice. It's ironic to think about it now, why should human beings fight to the death when they live well.

The special era has created a special character, Lu An doesn't care about face, face is not worth a few cents, the young master soldier from the big city is in the army, his face is still covered with mud, crawling underground, wearing exoskeleton armor for several days and not daring to take it off, allowing the centipede to crawl out a red mark on the skin. Lu Ann put the lining in front of his face. - This is a generation gap.

There is a generation gap between the children of the early 21st century and their grandparents who grew up together, and there is also a generation gap between Lu An, who has memories of future wars, and people in peacetime. This generation gap is reflected in the values of things.

Including volunteering here, most of the volunteers are from our school, and the practical classes are required to meet the standards. Luan, on the other hand, was an impulse, eager to try the work of wrenches and screws, these mechanical rivetings.

And Luan's intellect thought that this interest should be guided, screws, wrenches, circuits, which had been used a lot in previous lives, and now it was possible to familiarize himself with the tools here in a clustered state. Because in this world, it is not certain that machinery will be used in the future. When reason and emotion come to an agreement, behavior falls into place.

Lu An slowly pushed the 100-kilogram solar panel module into a fixed position with work gloves, using drag reduction in the process. The huge frame quickly reached the position with Lu An's one-handed action.

Suddenly, a hint of inappropriateness flashed in Lu An's heart, and he frowned and looked at the huge solar panel.

In a second-class rehearsal, Lu An unscrupulously raised his hand and punched the solar panel after pushing it, the fist was wrapped in an unobstructed film, and the aluminum alloy shell on the periphery was torn apart like a piece of paper. Unlike the first type of rehearsal, which is responsible for reality, in the second type of rehearsal, Lu An is taking the world to see the world as if he were watching an NPC scene. This chic blow caused the sideways eyes of the people around him. Of course, in the rehearsal, Lu An felt the silent gaze of the people around him, and couldn't help but feel a little fluttering about his identity as a powerful superclass.

Of course, in the subsequent rehearsals, the memories of this second type of rehearsal will quickly fade away, just like the fun building block games that I played stupidly when I was a child.

In this rehearsal, Lu An saw the broken shell, and the things exposed inside showed curiosity, and for a while changed from showing off to curious. Inside this shell is a special instrument. It seems that solar PV doesn't need this thing. In the useful memories of Lu An's previous life, the solar panels Lu An had simply repaired, and the modules were concise and clear. The lines are clear. And the box in here is too complicated.

In the second type of rehearsal, Lu An picked up a fragment, covered it with an unobstructed membrane, and with a gentle stroke, the sharp fragment cut through the box like a divine weapon, and looked at the inscription on the precision parts inside the box, Lu An understood, this is an atomic clock. In the midst of all the curiosity, this rehearsal ended.

However, the end of this rehearsal does not mean the end. Curiosity is not satisfied, and the feeling of great suspense and unsolved remains there. It was then passed on to the next rehearsal, and a large number of second-type rehearsals felt confused, which directly gave the first type of rehearsals a sense of curiosity.

In reality, this feeling came out very suddenly, but Lu An knew that he must have found something, so he would be curious, and then a large number of first type of rehearsals in the second half of the rehearsal (the first half accounted for about 95 percent, belonging to the peers of different thoughts), began to disassemble this photovoltaic device, Lu An quickly got the answer, perhaps it was recalled that he wanted to convey a curious feeling to himself in the first second type of rehearsal. From the second type of rehearsal discovery to the feeling to the real Luan confirming the specific things in the device, the whole process takes less than a second in the real physical world, and it is rehearsed in the reality of the physical world when Luan has not pushed the device to a fixed position. (Luan's "now" precedes the "now" of the physical world)

"Why is there an atomic clock device? What is this stuffing in here for? Luan was puzzled by the sudden appearance of this expensive remnant. It's expensive. According to the wire in the device, it seems that the device still sends the information through the mobile phone card. (In the information age, various unmanned environment monitoring stations send information to the national data network through this mode, which can send data every few minutes.) In the fifties and sixties of the twentieth century, the state relied on manual observation by personnel to collect this kind of data. It is then sent to the top by a fax machine-like machine. Manpower is exhausted, and data can only be sent once every hour. ）

Lu An has seen this model, Lu An did this during the Third World War, and before Meng Wei was finally killed, the work he did was also this ———— put out camouflaged models of environmental monitoring equipment. Make sure that the surroundings are not infiltrated by the enemy, and as for the ocean, the productive forces of the country are in full swing and scatter monitoring buoys in the sea, just like sprinkling potatoes. Productive forces are at full swing and a wide net is laid out against enemy warships.

"What the hell is this for?" In reality, Lu An installed the equipment and completed the job with a strong suspicion.

The camera switches, in a data center in Pudong, everyone inside is busy, and the people from the Dragon Department and the Xuanniao Department and the Tiger Department are all here.

Chen Fei looked at the city overview map on the big screen, there are dots on the overview map, the green one represents the one that is being activated, the red one represents the planned opening, the yellow one represents the start of construction, and the location of Linyuan College on the map is a yellow dot, with an average of one point per kilometer in Pudong. The layout of this scale is one of the characteristics of large projects, and the procurement funds for instrument and equipment projects are sufficient. Of course, even if the funds are sufficient, it cannot avoid a problem, that is, so many similar equipment cannot be produced by workshops, and must be mass-produced industrial products. It is precisely because it is a mass-produced industrial product, and many parts have inscriptions on it. Even the name and model of the industrial product are directly marked on the paint. Without these inscriptions, if this item is broken, what parts should be replaced and repaired? That's a lot of trouble. So there is a good atomic clock device in the solar panel, and it is not a top secret.

Looking at such a dense dot, he showed an anxious look on his face and said, "We don't have much time." Days are weakening at a rapid pace. Something must have happened to him. ”

Sheng Ruxing on the side said: "Can you only use this search method?" Chen Fei nodded and said, "Only through the accumulation of wrong probabilities can we know that he is active there." ”

Sheng Ruxing said: "In terms of statistical areas, the error probability of atomic clocks? So how much accuracy can be achieved. Sheng Ruxing was deeply worried about the data that could be given by a station with an atomic clock per kilometer. The atomic clock is very precise, and precision also means that if it is not well maintained, there will be errors. ”

Chen Fei muttered, "I don't know, but I should be able to determine which district he is." ”
