A week later, An Feng sent his parents away.

The old man is quite bored to tell the truth here, and there are few people around who can speak, and if they want to speak in English, they can understand at most one or two sentences, or to facilitate the occasional phrases of their daughter-in-law, it is still difficult to communicate with foreigners.

But in China, they have a lot of activities, and they are more comfortable than here.

If An Feng had a child or something, it would be interesting for them to come here, but it's a pity that he just pushes and pushes. In the end, An Feng flew them to the airport, used the passport to get the boarding pass, sent them to the security checkpoint, waved goodbye, and then turned back home.

The family is very lively, Joanna is teaching Xiaoyu the basics of dance, she has also learned some in China, and she has mastered it quickly, and then there are some simple movements of ballroom dancing. Ballroom dancing is very popular in the West, and it's embarrassing to go to a prom or something, and you're invited without dancing.

My sister is talking to Joanna's personal fitness trainer and agreeing on a fitness plan that suits her, which is very important for women who are over 30 and want to stay in shape, especially if they have money in their pockets, and they should also learn from Westerners and focus on themselves.

As for his brother-in-law, he talked to the phone and notebook for half an hour, and it was said that it was a domestic business or something. A group of South American servants at the winery are being trained by Brandon, and Wu Qian, who is a housekeeper, is also humbly learning, which is an orthodox English aristocratic style and very learned.

An Feng was very leisurely, put on an exoskeleton and took Xiaobai and Xiaohua to run.

Xiaobai has nothing to do and Xiaohua plays, according to the program set by An Feng, it also deals with Xiaobai according to the entry, high-end electric toys are very into the play, but there is no emotional communication throughout the whole process, a bit fake. An Feng sat and watched for a while. Stop Xiaobai and check Xiaohua.

Machinery means maintenance, especially when flexibility is required.

An Feng received sensor data through his portable computer, analyzed it, and decided to take it out tomorrow.

As for Xiaobai, who came over with his head, An Feng pushed it away: "Go aside!" You just have to eat your fill. What to maintain? ”

As a result, he was hugged by Xiaobai's thigh the next day, and he still had no choice but to take it away.

When you go out with An Feng, you can always meet all kinds of characters, and you can always meet all kinds of characters, and you are like a dog for IQ...... In this case, it is a positive description, because the IQ of canines is generally higher than that of felines, except, of course, Tibetan mastiffs that can sink aircraft carriers. Xiaobai formed a logical judgment on whether things are interesting or not.

……

An Feng jumped out of the plane, and the tiger and leopard followed. If you add a pair of jackals, it is a jackal, tiger and leopard rampant.

Some employees of An's Industry have become familiar with tigers, and various bionic machines have often appeared in recent months, such as pugs who want to pee on the territory everywhere. After putting on the imitation skin, those big eyes can really confuse people when they stare at people and make mistakes.

An Feng greeted someone he knew, and later went to the laboratory with a 3D printer.

He first tests the data, selects the CAD model of the printed part, and then prints the most suitable part directly on the target through precise printing technology, basically with a few clicks on the computer. CNC machine tools are no more than that, and it is more intelligent.

Data testing takes a long time. He cared about something else.

The superconductor company has found a way to mass produce superconductors more than two months ago, and the company's high-tech factory has almost been established with the full support of Ann's Industries, and it is expected that high-temperature superconductors will be put into production in the second half of the year, and samples have been obtained by many institutions.

The emergence of high-temperature superconductors once again shocked the world.

In recent years. There are too many new technologies that shocked the world, first the growth of super fertilizer, and then the emergence of GP company, which was crowned as the "strongest technology company" by the world media in just a few years.

Then there is a research center against the sky. Theory equals conclusion, leaving people speechless.

This time again, high-temperature superconductors...... Human beings are really numb, and if people know that the key to creating all this is a certain person, I am afraid that not many people will believe it. An Feng is already converging, and there is not much of his shadow in superconductor technology, and the only thing that is relevant is investment.

Samples from superconductor companies are now being verified by institutions all over the world.

An Feng had the sample early, and he implemented his previous idea: to place it in a cryogenic cooler and maintain it at minus 15 degrees Celsius to achieve superconductivity. The material is then cut and added with a 3D printer, and finally made into a short-distance parallel guide rail to connect superconducting wires.

After placing the superconductor in a low-temperature environment, it is energized, and the metal object is placed between the guide rails with a robotic hand, and at a moment's notice, the metal ball is pushed out by the invisible magnetic field force at a high speed, directly penetrating the two layers of composite panels in front of it, while the current used for emission is very small.

An Feng took off the experimental goggles and observed two layers of very thick composite plates, in the superconducting state, small currents have such strength, if it is a large current, or replaced with a fast-discharging capacitor, the speed exceeds 10,000 meters per second is no problem - it means that the era of electromagnetic weapons is coming.

Traditional gunpowder weapons have approached their own limits, the rate of fire is generally 2 to 3 times the speed of sound, it is difficult to increase, whether it is a gun or a tank gun, the muzzle velocity of 10,000 meters per second is a huge leap. If made into a single rifle, it will produce recoil that ordinary soldiers cannot withstand.

An Feng felt that it was unrealistic to make a rifle because it could only be used twice: one shot in the right arm, and another shot in the left arm...... Let's call it a day and go to the hospital.

But the purpose of his testing of electromagnetic weapons was for robots.

Electromagnetic weapons are very strong, they can be large or small, as small as a temporary assembly of hidden weapons, as large as a huge electromagnetic cannon on a warship, or even a magnetic cannon powered by nuclear energy in space, and it is possible to launch dozens of tons of shells. It's all-round, and it's inexpensive.

After An Feng tested it a few times, his thinking became clear.

Out of some untested ideas in his head, he took the time to construct the figure in front of the computer. Thanks to the GP editors of the smart program, he can now play with his little artistic cell and construct a relatively cool graphic from the inside out.

It took a little time to do it, and then color it, and the overall effect came out, and Anfeng connected to the 3D printer. Choose the fastest speed - and at the same time the most expensive. Full swing, about an hour later, the product is ready. 80% of the finished products are 3D printed, and the rest are semi-finished products.

An Feng took it out and took a moment to put it together.

This is an electromagnetic rifle, about seventy centimeters long. The shape is more sci-fi, and An Feng also takes the shape of some sci-fi games, and then designs the interior by himself. The electromagnetic gun is simple, a parallel rail, a wire that connects the rail, a capacitor and a magazine are installed at the end.

The bullet in the magazine is not the same as traditional, it does not have a cartridge and a charge, only a pointed bullet, when the trigger is pressed. When the power is turned on, the instantaneous energy of the capacitor passes through the parallel rail, and at the same time drives the miniature projectile chain, which sends the warhead to the end of the rail, and the generated magnetic field force pushes the warhead out, gaining a higher velocity than gunpowder weapons...... Theoretically, I just don't know how it will work in practice.

An Feng immediately looked for a target to test.

With his shoulder against the butt of the gun, which had been metal powder an hour ago, he aimed at a metal case in front of him. Pressing the trigger, only the slight sound of a strong electric current and a metal bullet flying out was heard. The body shook, the box flew out, An Feng put down the gun, rubbed his shoulders and walked to check.

"Awesome!" He looked at the opposite box.

This metal box is used to test the 3D printer, and it is used by bored people to test the plasma beam capabilities, which is the technology that the last four geniuses modified. It turned out to be easy to build ultra-high-strength structural steel, but now it is cooled by Anfeng's electromagnetic gun.

The rails have not yet entered the superconducting state, and if they are superconducting, the resistance of either the rails and the cable is zero, so the capacitor is chosen to release energy in a few seconds. It's going to be a very powerful individual weapon, but even now, it's going to have a lot of recoil to use.

An Feng continued to test muzzle velocity.

The average of repeated tests shows that the speed of the bullet leaving the chamber is 4000 meters per second, compared to the sniper rifle that pursues high speed, the latter is generally 1000 meters per second, and the rifle bullet is about 750 meters per second.

However, the recoil of the electromagnetic gun did not increase exponentially...... An Feng understood that the launch of gunpowder weapons was instantaneous kinetic energy, and the electromagnetic gun at least had parallel rails that were constantly accelerating, sharing the energy, and it was not added to him in an instant, and the result was bearable.

After testing it several times, An Feng was sure that he had copied the electromagnetic weapon in the sci-fi game.

It's like the last time the geniuses played with Star Wars lightsaber.

It's just that the price is too expensive, just start the machine and the expensive raw materials consumed, tens of thousands of dollars are gone...... This kind of thing that you can play if you want to play, and you can play if you want to have something right away, and you can generally afford it if you are rich and handsome. An Feng dismantled the gun afterwards and prepared to melt it with high-temperature plasma.

He doesn't plan to promote lethal weapons, such a high unit price, not everyone can afford to consume it, and he doesn't like the current appearance very much. You have to redesign it, preferably modular, and get a few to take home as a souvenir. When there is an emergency, it may come in handy.

Seeing that there is still a lot of time, An Feng found some cool firearm materials on the Internet, there are many models of electromagnetic guns in movies or games, some are purely eye-catching, and it is inconvenient to actually use, and some are modified according to existing firearms, and modularization is also difficult to carry out.

An Feng still found a suitable one, the gun is 65 cm long, it is very compact, it can be divided into three main parts: the barrel, the battery block, and the butt part. The structure of the electromagnetic gun is simple, and there is no need to worry about bullet shelling, muzzle flame, shooting airflow or something, basically powering up is firing.

Therefore, its modularity is very simple, the highest cost in the three-stage type is the battery module, which is specially supplied by GP Energy, and the cost is estimated to be 30,000 yuan, if it is on sale, it will not be able to earn back without 50,000 yuan. As for the barrel, An Feng originally wanted to use superconductors, but superconductors still have to be refrigerated, which will increase weight and recoil, and it is unrealistic to use alone, so in the end it is still so suitable at present.

While waiting for the production, An Feng went to touch other technologies.

There are a lot of interesting things in the lab, such as the modified exoskeleton that An Feng wears, carrying a high-energy battery pack on his back, and then turning out a plasma launcher, and Hoffman and other technocrats who design the handle in the style of Star Wars, and the end can be connected to a high-voltage cable or an exoskeleton battery.

The battery attached to the exoskeleton means that the lightsaber can be carried around.

An Feng connected the cable of the "lightsaber" to the battery pack, although it can't be as light as in the movie, it is still connected to the wires, but it is already very flexible, the high-energy battery is enough to maintain the plasma jet for an hour, plus the flexibility of the exoskeleton, it is very exciting to turn off the lights and play with the lightsaber.

After he destroys two targets, a table, and nearly burns out the printer, the electromagnetic gun is built.

An Feng assembled and disassembled it several times, and it could be completed in six or seven seconds, and it would shoot when it was powered on, and the accuracy was not outstanding, but due to the fast initial velocity, the 300-meter distance was completed in 0.1 seconds, even if the influence of gravity and wind speed was considered, the 300-meter bullet was infinitely close to a straight line.

So it's in a short distance, accuracy easily flicks a sniper rifle a few streets.

Finally, he also created a special case for the gun, which can be used to put the segmented electromagnetic gun and lightsaber...... For the time being, the United States lacks laws on the management of electromagnetic weapons, and in theory, An Feng can blatantly carry it out, but it is better to keep a low profile.

Before the legal ban was introduced, he could seize the time to build a dozen more lightsabers. Later, when the U.S. government says that it cannot privately possess electromagnetic rifles and Star Wars weapons...... And he earned it. Laws are generally aimed at groups after they have been enacted, and those that have existed before them are difficult to restrict. (To be continued......)
