A week later, An Feng saw his parents away.

It's boring to tell the truth here, and there are not many people around. If they say that they are all in English, they can understand one or two sentences at most, but it's just to make it easier to listen to the occasionally phrases that appear to their daughter-in-law. It's still a lot of difficulty to communicate with foreigners.

However, in the country, they have a lot of activities and are more comfortable here.

If An Feng had a child or something, it would be interesting for them to come here, but unfortunately he just pushed and pushed. Finally, An Feng drove them to the airport, used the passport to book the ticket to get the boarding pass, sent them to the security checkpoint, waved goodbye, and then returned home.

The house is very lively. Joanna is teaching Xiaoyu's basic dance. She also learned some in China and mastered it very quickly. Then there are some simple movements of ballroom dance. Ballroom dance is very popular in the West. It will be embarrassing to attend a dance party or something. If you are invited to dance without being able to do it.

My sister was communicating with Joanna's personal fitness coach and agreed on a fitness plan that suits her. This is very important for women over thirty and want to maintain their shape, especially when they have money in their pockets, they should learn from Westerners and focus on themselves.

As for his brother-in-law, he talked to the phone and notebook for half an hour, which is said to be a domestic business. A group of South American servants at the winery are being trained by Brandon. Wu Qian, as a female housekeeper, also learned modestly. This is the orthodox British aristocratic style and is very knowledgeable.

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

Xiaobai had nothing to do and had a fight with Xiaohua. According to the program set by An Feng, it also dealt with Xiaobai according to the entry. High-end electric toys are very adept, but there is no emotional communication throughout the whole process, which is a bit false. An Feng sat and watched for a while, called Xiaobai to stop him and checked Xiaohua.

Machinery means maintenance, especially those that require high flexibility.

Anfeng received sensor data through his portable computer. After analyzing it, he decided to take it out tomorrow.

As for Xiaobai who was approaching with his head, An Feng pushed it away: "Go on the side! Just eat enough, what should I maintain?"

As a result, Xiaobai held it away the next day, and he still had no choice but to take it away.

When you go out to play with An Feng, you always meet all kinds of people. For IQ like dogs... in this case, it is a positive description, because the IQ of the canine family is generally higher than that of the cat family. Of course, except for Tibetan mastiffs that can sink aircraft carriers. Xiaobai formed a logical judgment on whether things are interesting or not.

...

An Feng jumped off the plane and followed the tiger and leopard. If another pair of jackals were added, it would be jackals, tigers and leopards were rampant.

Some employees of Anshi Industrial are already familiar with tigers. In recent months, various bionic machinery often appear, such as beetles that want to pee everywhere, and put on simulated leather bags. When those big eyes are staring at people and committing crimes, they can really confuse people.

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

He first conducted data testing, selected the CAD model for printing parts, and then directly printed the most fitting parts on the target through precise printing technology. He basically only needed to press a few times on the computer throughout the process. This is the case with CNC machine tools, and it is more intelligent.

The data test takes a long time, so he will care about something else.

Superconductor companies have found a way to mass-produce superconductors more than two months ago. With the strong support of Anshi Industry, the company's high-tech factory has almost been established. It is expected that high-temperature superconductors can be put into production in the second half of the year. Samples have been obtained by many institutions.

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

In recent years, too many new technologies have shocked the world. First, the growth of super fertilizers against the will of nature, and then the GP company that emerged suddenly. It was crowned the "strongest technology company" by the world media in just a few years. IBM and other things can only sigh that the Yangtze River is pushing the previous waves.

With another research center that is against the will of heaven, the theory is equivalent to the conclusion, leaving people with nothing to say.

This time, we come to high-temperature superconductors...humans 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 converging, and superconducting technology cannot see much of his shadow. The only connection is investment.

Now institutions around the world have come into contact with samples from superconductor companies. They are also being verified.

An Feng had a sample early on. He implemented his previous idea: to place it in a low-temperature refrigerator to maintain superconductivity at minus 15 degrees Celsius. Then, the material was cut and added to the structure with a 3D printer, and finally made a short-distance parallel guide rail to connect superconducting wires.

After putting the superconductor in a low temperature environment, turn on the power and use a robot to place a metal object between the guide rails. In the instant, the metal ball was pushed out by an invisible magnetic field force, and the speed was very high, directly penetrating the two layers of composite boards in front of him, while the current used for emission was very small.

An Feng took off his experimental goggles and observed two very thick composite boards. In superconducting state, small currents have such strength. If it is a large current, or if it is replaced with a capacitor with fast discharge, the speed exceeds 10,000 meters per second is no problem - which means the arrival of the era of electromagnetic weapons.

Traditional gunpowder weapons are close to their own limits, and their firing rate 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 initial velocity of the 10,000 meters per second is a huge span. If it is a single rifle, it will produce recoil that ordinary soldiers cannot bear.

An Feng felt that it was unrealistic to make a rifle, because it could only be used twice: fire one shot on the right arm, change the left arm and fire another shot... and finish the work and go to the hospital.

But his purpose of testing electromagnetic weapons was to prepare it for the robot.

Electromagnetic weapons are very powerful, both large and small, as small as temporary as hidden weapons, to huge electromagnetic guns on warships, or even magnetic guns driven by nuclear energy in space, and firing shells weighing dozens of tons. They are all-round and inexpensive.

After testing Anfeng several times, his ideas became clear.

Out of some unverified ideas in his head, he spent some time constructing graphics in front of his computer. Thanks to the person who edited the smart program in GP, ​​he can now use his few artistic cells to construct a cooler graphics from the inside to the outside.

It took some time to do it and then color it. The overall effect was released. Anfeng connected to the 3D printer and chose the fastest speed - and the most expensive one. It started with all its strength. After about an hour, the product was made. 80% of the finished products were 3D printed. The others were semi-finished.

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

This is an electromagnetic rifle, about 70 centimeters long and has a relatively science fiction shape. An Feng also uses the appearance of some science fiction games and then designs the interior by himself. The electromagnetic rifle is very simple, a parallel guide rail. The wires connecting the guide rails are connected to the wires and install capacitors and magazines at the end.

The bullets in the magazine are different from the tradition. They have no cartridges and charges, only sharp-length 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 the cable will drive the micro-engine chains. The cables will send the bullets to the tail end of the guide rail. The generated magnetic field force pushes the bullets out and obtain a higher speed than gunpowder weapons... In theory, it is just that I don’t know what the actual effect is.

An Feng will find a target to test it immediately.

His shoulders were pressed against the butt stock that was still metal powder an hour ago, aiming at a metal box in front of him. When he pressed the trigger, he heard only the strong current and the slight sound of metal bullets flying out. His body shook and the box flew out. An Feng put down his gun, rubbed his shoulders and went to check.

"Awesome!" He looked at the box he was wearing.

This metal box is used to test 3D printers and is used by boring people to test plasma beam capabilities, which is the technology that last time the four geniuses were transformed. The result proves that it can easily create ultra-high-strength structural steel, but now it is cool and worn by An Feng's electromagnetic gun.

The guide rail has not yet entered the superconducting state. If the superconducting, both the guide rail and the cable, the resistance of the superconducting system is zero, and choosing to let the capacitor release energy in a few seconds, it will be a very powerful individual weapon, but even now, the recoil force will be very high when used.

Anfeng continued to test the initial velocity of the vent.

The average value of repeated tests shows that the speed of the bullet leaving the chamber is 4,000 meters per second. Compared with the sniper rifle that pursues high speed, the latter is generally only 1,000 meters per second. The rifle bullet is about 750 meters per second. Compared with the front and back, the speed of the electromagnetic gun is very terrifying.

However, the recoil of the electromagnetic gun did not increase in multiples... An Feng understood that the launch of gunpowder weapons is instantaneous kinetic energy, while the electromagnetic gun at least has parallel guides that are constantly accelerating, sharing the energy, and not being added to him in an instant, but the result is to withstand it.

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

Just like the Star Wars Lightsaber that the geniuses played last time.

It's just that the cost is too expensive. Just when I started the machine and the expensive raw materials I consumed, tens of thousands of dollars disappeared... This kind of thing I can play when I want to play, and I want to have something right away. Generally, only the tall, rich and handsome guys can afford it. An Feng dismantled the gun afterwards and prepared to melt it with high-temperature plasma.

He does not intend to promote destructive weapons. Such a high unit price is not affordable for anyone. Moreover, he doesn't like the current appearance very much. He has to redesign it, preferably modular, and take it home as a souvenir. When there is an urgent matter, it may come in handy.

Seeing that there was still more time, An Feng searched for some cooler gun materials online. There were many models of electromagnetic guns in movies or games. Some were purely eye-catching and inconvenient to use. Some were modified based on existing guns and modularization was also difficult to perform.

An Feng still found a suitable one. The gun is 65 cm long and very compact. It can be divided into three main parts: the barrel, the battery block, and the butt stock part. The electromagnetic gun is simple to construct, so there is no need to worry about bullet casting, the rifle flame, the shooting airflow, etc. Basically, power is to open fire.

So its modularity is very simple. The most expensive one in the three-stage type is the battery module, which is specially supplied with GP energy. The cost is estimated to be 30,000. If it is on the market, it will not be able to make a profit without 50,000 yuan. As for the barrel, Anfeng originally wanted to use superconductors, but superconductors still had to be cooled, which would increase weight and recoil. It is unrealistic to use single people. In the end, it is still the same as it is currently.

While waiting for production, An Feng will touch on other techniques.

There are many interesting things in the laboratory, such as An Feng's modified exoskeleton, with a high-energy battery pack on his back, and then he turned out the plasma transmitter. Hoffman and other technical homes are designed in the style of Star Wars. The end can be connected to high-voltage cables or exoskeleton batteries.

The battery connected to the exoskeleton means that the lightsaber can be carried with you.

An Feng connected the cable of the "lightsaber" to the battery pack. Although it is not as light as in the movie, it still connects the wires, but it is already very flexible. The high-energy battery is enough to maintain the plasma jet for an hour. With the flexibility of the exoskeleton, it is exciting to turn off the light and play with the lightsaber.

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

Anfeng assembled and split it several times, and it could be completed in six or seven seconds. When powered on, it would be fired, and its accuracy was not outstanding. However, due to the fast initial speed, the 300-meter distance was completed in 0.1 seconds. Even if the influence of gravity and wind speed was taken, the 300-meter bullet was infinitely close to a straight line.

So it is easily overshadowed by a sniper rifle within a short distance and with accuracy for several streets.

Finally, he specially built a special box for the gun, which can put segmented electromagnetic guns and lightsabers inside... At present, the United States has a lack of management of electromagnetic weapons. In theory, An Feng can take it out with a blatant way, but it is better to be low-key.
