i have a dump

Chapter 852 Last transaction

Of course, the most important reason why it is less used is the restrictions in various aspects.

Like machines.

For example, if you make a toy worth ten yuan, it is likely to cost hundreds or even thousands of yuan.

Except for some special fields, this technology has not yet been able to be used by civilians.

And this technology, in the computer, is very complete.

Also very well developed.

Those who are perfect don't know how to be perfect.

For hundreds of years, I don't know how many children have completed it as homework.

And also remodeled.

For example, dedicated 3D printers used in automobile production, mobile phone production, etc.

Large-scale printers used in construction have been able to achieve mass production, and the cost is very low.

Even if you use traditional cement and steel bars, etc., print out the house.

However, with modern technology, there is no way to use steel bars to print large buildings.

It's not that the technology 500 years later can't do it, but the current technology can't do it.

After 500 years, it has been possible to make crystalline silicon into a fluid.

Buildings are then printed with this fluid material.

But modern technology can't do it.

At least, Qin Feng did not find similar information in the computer.

There is also movie-making software.

This is a kind of software.

A very popular little game.

Because it is fun, and the previous children can't play large games, this kind of small software is common among the previous children.

The principle is simple.

It is similar to the current AI face-changing technology.

AI face change, in simple terms, is a relatively high-end cutout.

It's just that the photo is turned into a video.

For example, if you are watching Journey to the West and feel that you are more like a master of Tang Sanzang, then you can change Tang Sanzang's face into your own.

It's that simple.

The movie making applet is even simpler.

Perform a comprehensive information entry for the individual, then select the movie character you want to replace, and then click Generate.

One-click generation, whether crying or laughing.

Even the voice can become your own voice through the recording of sound elements.

In this way, you can completely turn yourself into the protagonist in the movie.

Enjoy situations that no one else has.

However, this technology is relatively low-end after 500 years.

If it weren't for the fact that the children in the past couldn't play large games, and couldn't connect to an external computer through a personal computer and enjoy the life of the characters in the movie, I'm afraid this kind of small program would have disappeared in the long river of history.

However, this technology is very suitable to take out.

At least, it is still very good to control it yourself.

Then there is the network firewall and network supervision after 500 years.

Because everything after 500 years is basically under the Internet.

If this part is not done well, even a small accident may cause an irreparable disaster.

In terms of network security after 500 years, it is definitely a disaster level in the game.

It is simply impossible to break it.

Because of the fear of computer programs attacking humans, in terms of network security, humans 500 years later have simply achieved the ultimate.

At least, in the current era of binary computers, it is absolutely impossible to break through the network protected by this kind of network security.

"Okay, just take out these three. If you take out too many at once, I'm afraid everyone can't accept it. After all, I'm just an ordinary person."

At the end, Qin Feng himself laughed.

Yes, he is just an ordinary person.

However, he is an ordinary person with a plug-in.

What other people can't do in a lifetime, he only needs to recycle some plane garbage.

If there is no plane garbage dump, he is just a poor guy now.

How could it be possible to have everything now?
How could there be so many beauties?

Therefore, the current Qin Feng is still very content.

It's just that during the Chinese New Year, an experience in the plane garbage dump made Qin Feng realize that time was running short.

After downloading all three technologies, Qin Feng walked to the light curtain.

Clicked the transaction again.

This time, it was a deal with Meng Fanchao.

One hundred kilograms of black soil.

One catty of black soil is exchanged for one hundred catties of foam steel additives.

Including this time, Qin Feng exchanged a total of [-] kilograms of black soil and foam steel additives.

Four thousand kilograms, or four tons.

There is not even a cubic meter of additives for four tons of foam steel.

According to Meng Fanchao, he learned from many sources that this foam steel additive was first discovered on a meteorite.

Later, with the development of science and technology, people found a huge meteorite block from outer space, and that meteorite was an additive of foam steel.

Then they pulled the huge meteorite back to the earth where they were.

It's just that, for such a long time, the foam steel additives are almost used up, and if you want to, you can only look for it in outer space.

After knowing the news, Qin Feng had no idea of ​​asking Meng Fanchao to continue collecting, and directly exchanged the last [-] kilograms of black soil for [-] energy points. Then, the exchange page of the water world disappeared from the light screen.

At the same time, the black soil in the warehouse also disappeared.

His deal in Water World is completely over.

After converting to six thousand energy points, four tons of foam steel additives, the price paid was one ton of black soil.

To be honest, Qin Feng was still a little bit disappointed when the deal of Water World was over.

This is, after all, a chicken that lays eggs.

If it wasn't that he could only trade one ton, Qin Feng could buy Robinson's entire island for him, and then trade it to Water World.

Unfortunately, I can only think about it.

With these six thousand energy points and four tons of foam steel additives, Qin Feng is already very satisfied.

Next, Qin Feng began to prepare foam steel according to the recipe.

The production of foam steel is very simple. The steel is melted, and then a certain proportion of foam steel additives are added. After cooling, the raw material of foam steel will be formed.

Surprisingly, when the steel cools down, it becomes a block-like solid, while the raw material of the foam steel is also block-like when it cools down, but its hardness is extremely low, and it can be crushed by hand.

When making foam steel, you only need to add pure water in proportion.

Foam steel and water are added in a ratio of [-]:[-] to form foam steel with a hardness comparable to that of titanium alloy.

After making a meal of foam steel raw materials, and using the foam steel raw materials to make a one-meter-high foam steel villa model, Qin Feng stopped.

As for the physical and chemical properties of the foam steel, Liu Jiangtao has also been tested.

No matter from which aspect, it is completely rolled alloy, even better than titanium alloy.
