Chapter 208

Sun Dingze was actually quite envious of Song Ming, because the strategic position of space compression technology was too important.

If humans can fully master this technology, they can send elites to infiltrate the city, rescue all the important equipment, and then quickly reorganize the civilized society, counterattack the variants, and take the city back.

It's a pity that the research and development of this technology is too difficult, and until now, Sun Dingze has only seen really practical finished products here in Song Ming.

After sighing for a while, Sun Dingze suddenly heard Song Ming say, "I want to buy some gardening robots." ”

"Gardening robots? Why did you buy that? Don't tell me what kind of garden you're in the mood to get now. ”

Sun Dingze was quite surprised, before the Day of Destruction, the park or flower market would order some agricultural robots, after adjusting the program, it was a professional gardening robot, which could complete the work of cultivating flowers and building fences, and was even more professional than the vast majority of humans.

It's just that after Doom Day, because of the shortage of resources and the lack of use, there was basically no production of gardening robots.

"You just say whether to sell or not."

"Selling can sell ......"

"Then don't ask so much, I'm useful, by the way, I want to use radiation-resistant materials and structures, my situation there is a bit special."

Song Ming originally planned to let those slaves cultivate the radiation moon season, but he also had to prepare things like radiation resistance suits for them, and also took into account the problem of working hours, which was too troublesome, and finally simply thought about it, just replace it with robots, anyway, the robot technology in this world is also very powerful, and it can completely replace a lot of human labor.

but also radiation resistant materials......

Sun Dingze was even more puzzled in his heart, but he didn't continue to ask, just nodded and said, "1 1 point contribution, how much do you want?" ”

Song Ming glanced at his contribution, after these few cooperations, there were already more than 5 million contributions in his personal account, but considering that he still had to leave some of the purchase technology, after thinking for a while, he said, "Let's have 100 first." ”

100 horticultural robots, 20 at a time can meet the demand, in order to prevent irreparable damage to the robot caused by radiation, it needs to be replaced every once in a while, 100 is definitely enough.

After the two completed the transaction, Sun Dingze said: "I'll arrange it, and I can pick up the goods tomorrow." ”

"Okay, then I'll go first."

Song Ming got up and left the office, and after contacting Xiao Yuening, he took the elevator to the top floor.

[You're back!] Xiao Yuening was quite happy when she saw Song Ming, [What is the result of the weapon test? Does it work? Is it easy to use? Where is the collected data? Show me! I can't wait to do the next step of my research! 】

"Good is easy to use, but the problem is that it only works for loiters."

Song Ming took out the electron gun and handed it to her, and by the way, transmitted the data collected during the battle to Xiao Yuening, and then said, "I wonder if it's because the characteristic data collected at the beginning came from the wanderer. ”

[There is a possibility that there are differences in the nanogroup data structure, operating principle, signal frequency, and strength between different disambiguities, and I would be surprised if it could be fully effective.] Now let me take a look at the test data. 】

Xiao Yuening opened the test data and quickly skimmed through it in his mind.

Seeing that she was busy, Song Ming simply entered Alayya's database again, and began to think about what would be better to choose for the next technology that could be used in modern society.

The improved purified water cup was prepared for Liang Jinsong, and if nothing else, it should eventually wait for the military's purchase order, and the temporary production capacity is difficult to meet the needs of the civilian field.

The resource recycling plant is a channel to prepare for the establishment of a resource recovery plant to improve resource utilization, and it is also a channel to obtain various materials.

The sales of sleep mattresses are now very hot, but the domestic market has entered a stable period, unless the foreign market is opened, it is difficult to have explosive growth, so the demand for expanding production capacity is not strong, and the additional production capacity obtained from the shelter can already meet the needs.

The production capacity of the nano synthesis factory is so strong, it would be a bit too wasteful not to use it.

At this time, Song Ming suddenly thought of his old job.

Sewage treatment.

Like desalination, in the modern world, sewage treatment is also a high-input, low-output, heavily dependent on government subsidies for social welfare industries, almost few enterprises are willing to invest in sewage treatment, because the input-output ratio gap is too large, 100 million yuan into the film market, a year or two later may reap 200 million, 500 million, or even 1 billion returns, but the same capital invested in the sewage treatment industry, may only have 10 million income in a few years.

This industry is clearly not liked by the capitalists who are eager for quick success.

But if there is no sewage treatment plant, with the efficiency of modern people to produce sewage, it will not be long before the whole city will become stinky, and all rivers will become stinky ditches, not to mention the bathing water, drinking water is estimated to be a problem.

Seawater desalination and sewage treatment are two complementary industries, one is to solve the problem of insufficient fresh water, the other is to solve the problem of how to reuse dirty water, if the problems encountered by these two industries can be solved, the pollution problem faced by the modern world can be solved at least more than half.

Improving the living environment in the modern world is one thing, but the most important thing is that if he can solve the problems faced by the desalination and sewage treatment industries in one go, his position in the eyes of the country's top brass will definitely be more important, and he will be qualified to work cheaply.

"Alayah, inquire about the technology related to sewage treatment."

After Song Ming gave the order, the relevant technical information soon appeared in front of him.

There are quite a lot of sewage treatment technologies in the apocalyptic world, and in addition to the AAO technology that has been eliminated, there are many new technologies that are eye-catching.

For example, "Photocatalyst Reduction Method", "NRD (NanoRobot Decomposition) Method" and so on.

Photocatalyst is a method of using new materials to be added to the sewage treatment tank and using the strong decomposition of the material under specific conditions to treat the composition of sewage, which has a special effect on the sewage polluted by heavy metals, but the effect on domestic sewage is average.

The NR law is a new method born after the outbreak of nanorobot technology, and its treatment principle is completely different from the previous treatment methods, not only does not have a thick and thin grid, an aeration tank, or even a biological pool, its structure is a very unique linear structure, water inlet - reservoir (also known as buffer tank) - treatment pool - high-efficiency filter tank - advanced treatment - water outlet.

That's right, it's as simple as that.

Among them, the most technical content and the core of the whole process is the treatment tank.

According to a brief introduction, the treatment pool uses specially designed nanorobots, which will completely decompose everything in the sewage except water molecules into basic single atoms, which is actually quite dangerous, because if people accidentally fall into the treatment pool, they will also be instantly decomposed, so after the treatment pool is designed and manufactured, it is a complete semi-sealed structure, leaving only the inlet and outlet holes.

On the basis of this treatment process, the reusable resources will be reused through the resource recovery system to generate elemental crystals, the most typical example is the heavy metal ions in the wastewater, which will be recycled and reused, and the waste organic matter or macromolecular inorganic matter such as plastics will be broken down into harmless monoatomic structures.

After thinking about it for a moment, Song Ming said, "Exchange the NRD method sewage treatment process." ”

Alaya deducted his 500,000 contributions, and then the specific process technology related to the NR method and the production process of nanorobots were all aggregated into a data package.

Sure enough, it's the end of the world, and such a powerful technology can be obtained with only 500,000 contributions......

After exchanging this technology, Song Ming thought for a while, and then exchanged a few technologies that were easy to realize.

For example, the adaptive comfort seat technology that is matched with the sleep mattress, and the lithium-air battery technology and graphene battery technology that are being studied in the laboratory in the modern world. And now the exchange price of the general energy pack battery technology commonly used in the apocalyptic world is very high, and the required contribution is as high as 10 million, and the room temperature superconductor material is also used, so it is also necessary to exchange the room temperature superconductor material synthesis technology.

But after all, it is a material technology that changes the world, and it is understandable that the price is so high.

After getting the battery technology, Song Ming thought of the artificial intelligence of the home intelligent control center again, and after thinking about it for a while, he simply inquired about the information of the last few generations of smart phones before the popularization of smart chips, and exchanged it.

After a bunch of technical information is exchanged, more than 5 million contributions are almost spent, mainly because the price of battery technology is relatively high.

This contribution comes and goes quickly......

Song Ming sighed with emotion, and then left Alayya's database.

In the corner, a lone figure squeezed his little hand and watched him leave......

[Coming back? Looking for technology again? 】

Xiao Yuening glanced back at him, then ran over excitedly, looking at him with wide eyes: [I have roughly analyzed the reason, if nothing else, it is what you guessed, because the samples we collected are from wanderers, so in the end, the data model I designed will only take effect on wanderers. 】

Obviously his mouth didn't move, but the communication in his head was hot, Song Ming felt very awkward when she stared at her, and after pushing her face away, he said: "It means that if I can get you the data of the live sample of the predator, you can once again develop a weapon that can kill the predator in seconds?" ”

[Theoretically, that's true, but ......] Xiao Yuening's thinking paused for a rare moment, [But it's not that simple, the nanomachine swarm structure and the way of exchanging data between different disambiguities are almost completely different, and they need to be re-analyzed and re-developed, and I estimate that the more powerful the disagreements, the more difficult it is to collect data, and the more difficult it is to develop weapons. 】

After thinking for a moment, Song Ming said, "It's good to be able to develop new weapons against wanderers and predators, they account for at least 50% of the number of distorted variants, and for the vast majority of ordinary people, it is much safer to eliminate them." ”

[Then you also have to help me collect the living data of the predator first, and by the way, there is also the self-destructor. 】

Song Ming had a black line: "Don't think about it if you blow yourself up...... That thing explodes as soon as it gets close, and the tranquilizer gun is ineffective, so it's impossible to start, how to collect live data? ”

Xiao Yuening thought for a moment and said, [Maybe you can use data intrusion to interfere with the normal operation of the nanomachine swarm and make it stop acting? 】

"How?"

[Similar to hacking, do you know about DDoS attacks? Overflow the other party's cache with packet influx......]

Song Ming suddenly realized: "You know, distributed denial-of-service attack, is this method effective?" ”

[Maybe there is, maybe not, who knows if you don't try it?] 】

Xiao Yuening happily picked up Song Ming and ran outside: [What are you waiting for? Let's go! 】

Song Ming dragged her back with a black face.

It's snowing outside, go your sister!
