Tall, rich and handsome toys

A week later, An Feng sent his parents away.

It's quite boring for the elderly to tell the truth here, and there are not many people around who can talk. If they speak English, they can understand a sentence or two at most. , It is still quite difficult to communicate with foreigners.

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

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

  The house is very lively. Joanna is teaching Xiaoyu the basics of dance. She also learned some in China, and she mastered it quickly. Then there are some simple movements of ballroom dancing. Ballroom dancing is very popular in the West, and if you go to a ball or something, it would be embarrassing if you are invited and you can't dance.

My sister is talking with Joanna's personal fitness trainer to agree on a fitness plan that suits her. This is very important for women who are over 30 and want to keep in shape, especially when they have money in their pockets. It is time to learn from the West People, focus on yourself.

  As for his brother-in-law, he talked on 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 in the winery are being trained by Brandon, and Wu Qian, who is the housekeeper, is also learning modestly. This is the orthodox British aristocratic style and is very knowledgeable.

  An Feng is very leisurely, wearing an exoskeleton and taking Xiaobai and Xiaohua for a run.

  Xiaobai fights with Xiaohua when he has nothing to do. According to the program set by An Feng, it also deals with Xiaobai according to the items. The high-end electric toys are very interesting, but there is no emotional communication in the whole process, which is a bit fake. An Feng sat and watched for a while, then told Xiao Bai to stop and check Xiao Hua.

  Mechanical means maintenance, especially if the flexibility is high.

  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 away! You can just eat enough, what do you take care of?"

   As a result, Xiao Bai hugged his thigh the next day, but he still had no choice but to take it away.

  When I go out with An Feng, I can always meet all kinds of people. IQ is like a dog... In this case, it is a compliment, because the IQ of canines is generally higher than that of cats, except of course the Tibetan mastiff that can sink an aircraft carrier. Xiaobai formed a logical judgment on whether things are interesting or not.

  …

  An Feng jumped off the plane, followed by Tiger and Leopard. If you add a pair of wolves, it will be a rampage of wolves and tigers.

Some employees of An's Industry are no strangers to tigers. In the past few months, various bionic machines have appeared frequently, such as the pug dog who wants to urinate and mark the territory everywhere. When committing two crimes, it can really confuse people.

  An Feng greeted the people he knew, and then went to the laboratory with 3D printers.

He first conducts data testing, selects the CAD model of the printed part, and then directly prints the most suitable part on the target body through precise printing technology. Basically, he only needs to press a few times on the computer in the whole process, and the CNC machine tool is no more than that, and its The degree of intelligence is higher.

  The data test takes a long time, so he has to worry about other things.

The superconductor company has found a way to mass-produce superconductors more than two months ago. With the full support of Anshi Industrial, the company's high-tech factory has almost been established. It is expected that high-temperature superconductors will be put into production in the second half of the year. organization obtains.

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

In recent years, there have been too many new technologies that have shocked the world. First, the growth of super fertilizers against the sky, and then the emergence of GP company. It was crowned as the "strongest technology company" by the world media in just a few years. IBM what Everyone can only sigh with emotion that the waves behind the Yangtze River push forward the waves ahead.

   Then there is another research center against the sky, the theory is equal to the conclusion, leaving people speechless.

  Here we come to high-temperature superconductors this time... Human beings are really numb. 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 restraining himself, and he can't see much of his shadow in superconductor technology. The only thing that is related is investment.

   Now institutions all over the world have access to the samples of superconductor companies and are also verifying them.

  An Feng had a sample early, and he implemented his previous idea: put it in a cryogenic refrigerator and keep it at minus 15 degrees Celsius to achieve superconductivity. Then cut the material with a 3D printer and add structures, and finally make short-distance parallel guide rails to connect superconducting wires.

After placing the superconductor in a low-temperature environment, turn on the power, and use the robotic hand to place a metal object between the guide rails. In a flash, the metal ball is pushed out by the invisible magnetic force at a high speed, and directly penetrates the two layers of composite board in front of it. However, the current used for emission is very small.

An Feng took off the experimental goggles and observed the two layers of very thick composite plates. In the superconducting state, the small current has such an intensity. If it is a large current, or replace it with a fast-discharging capacitor, the speed will break through 10,000 meters per second. Problem—means the coming of the era of electromagnetic weapons.

  Traditional gunpowder weapons are already close to their limits. The rate of fire is generally 2 to 3 times the speed of sound, which 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 it is made into an individual rifle, it will produce recoil that ordinary soldiers cannot bear.

  An Feng thinks it is unrealistic to make a rifle, because it can 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 electromagnetic weapons is for robots.

Electromagnetic weapons are very powerful, and can be large or small, as small as a temporary assembled concealed weapon, as large as a huge electromagnetic gun on a warship, or even a magnetic gun driven by nuclear energy in space. It is possible to launch tens of tons of shells. of. It's versatile and inexpensive.

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

  Because of some untested ideas in his head, he spent some time constructing graphics in front of the computer. Thanks to the person who edited the smart program in GP company, he can now use his limited artistic skills to construct a cool graphic, from the inside to the outside.

   It took some time to make it, and then color it, and the overall effect came out. Anfeng connected the 3D printer and chose the fastest speed—it was also the most expensive. With full power, after about an hour, the product was made. 80% of the finished products are 3D printing, and the rest are semi-finished products.

  An Feng took it out and took some time to assemble it.

  This is an electromagnetic rifle, about 70 centimeters long, with a more sci-fi shape. An Feng also drew the shape of some sci-fi games, and then designed the interior himself. Electromagnetic guns are simple, a parallel rail, wires connecting the rails, capacitors and magazines mounted on the end.

The bullets in the magazine are different from the traditional ones. It has no cartridges and charges, but only pointed bullets. When the trigger is pressed and the power is turned on, the instantaneous energy of the capacitor will pass through the parallel guide rails, and at the same time drive the miniature bullet chain, and the bullets will The chain sends the warhead to the end of the rail, and the resulting magnetic force pushes the warhead out, achieving higher speeds than gunpowder weapons...in theory, just don't know how it works in practice.

  An Feng immediately found a target to test.

With his shoulder against the gun stock that was still metal powder an hour ago, he aimed at a metal box in front of him, and pressed the trigger, only to hear a strong current and the slight sound of metal bullets flying out, his body shook, the box flew out, An Feng put down the gun, Rub your shoulders and go check.

   "Excellent!" He looked at the suitcase he was wearing.

This metal box is used to test the 3D printer. It was used by boring people to test the ability of the plasma beam, which is the technology transformed by the four geniuses last time. It turned out that it can easily create ultra-high-strength structural steel, but now it is used by An Feng. The electromagnetic gun came to a cool pair.

The rails are not superconducting yet, and if they were superconducting, both the rails and the cables would have zero resistance, opting to let the capacitors discharge their energy in a few seconds would be a powerful individual weapon, but even now , The recoil force when using it is also great.

  An Feng continued to test the muzzle velocity.

The average value of repeated tests shows that the speed of the bullet leaving the barrel is 4,000 meters per second. Compared with the sniper rifle that pursues high speed, the latter is generally 1,000 meters per second, while the rifle bullet is about 750 meters per second. In contrast, the speed of the electromagnetic gun is very terrifying.

However, the recoil of the electromagnetic gun did not increase exponentially... An Feng understood that the firing of a gunpowder weapon is instantaneous kinetic energy, while the electromagnetic gun at least has parallel guide rails that are constantly accelerating, sharing the energy and not adding it to him in an instant. bearable.

  After testing several times, An Feng confirmed that he had copied the electromagnetic weapon in the science fiction game.

   Like the last time the geniuses played with Star Wars lightsabers.

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

  He doesn't plan to promote lethal weapons. Such a high unit price is not affordable for everyone, and he doesn't like the current appearance. It has to be redesigned, preferably modular, and get a few to take home as souvenirs. It might come in handy when something is urgent.

Seeing that there was still a lot of time, An Feng searched for some cool gun materials on the Internet. There are many models of electromagnetic guns in movies or games. Some are purely eye-catching and inconvenient to use in practice. Modularity is also hard to do.

  An Feng still found a suitable one. The gun is 65cm long and very compact. It can be divided into three main parts: the barrel, the battery block, and the butt. The structure of the electromagnetic gun is simple, and there is no need to worry about bullet ejection, muzzle flames, shooting airflow, etc. Basically, the gun is fired when it is powered on.

  So its modularization is very simple. Among the three-stage models, the most expensive one is the battery module, which is specially supplied by GP Energy. The cost is estimated to be 30,000. If it is on the market, it will not be able to earn back 50,000. As for the barrel, An Feng originally wanted to use a superconductor, but the superconductor had to be refrigerated, which would increase the weight and recoil, making it unrealistic for a single person to use, but in the end it was still suitable.

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

There are many interesting things in the laboratory, such as the modified exoskeleton worn by An Feng, with a high-energy battery pack on his back, and then flip out the plasma launcher. High-voltage cables can also be connected to exoskeleton batteries.

   Connecting to the battery of the exoskeleton means that the lightsaber can be carried with you.

An Feng connected the cable of the "light saber" to the battery pack. Although it is not as light as in the movie, it is still connected to the wire, but it is already very flexible. The high-energy battery is enough to maintain the plasma jet for an hour. Flexible, it is very exciting to play lightsaber with the lights off.

  After he destroyed two targets, a table, and almost burned the printer, the electromagnetic gun was built.

Anfeng assembled and disassembled it several times, and it can be completed in six to seven seconds. It shoots immediately when it is powered on. The accuracy is not outstanding, but due to the fast initial speed, the distance of 300 meters is completed in 0.1 seconds, even considering gravity and wind speed. The impact of the 300-meter bullet is also infinitely close to a straight line.

  So it is within a short distance, and the accuracy can easily beat the sniper rifle a few streets.

In the end, he specially built a special box for the gun, which can put the segmented electromagnetic gun and lightsaber inside... For now, the United States lacks laws on the management of electromagnetic weapons. In theory, An Feng can carry it out blatantly. But it's better to keep a low profile.

  Before the legal ban is introduced, he can seize the time to make more than a dozen more, matching the lightsaber. When the U.S. government says that electromagnetic rifles and Star Wars weapons cannot be privately owned...he will make money. Laws generally target groups after promulgation, while those that existed before are difficult to restrain.
