Lin Chen, who got the news, came to Bi Yuwei's private workshop, oh, now this is called the Blue Earth Organization Mechanical Technology Research Institute.

Well, and it's a research institute dedicated to Bi Yuwei, a technology maniac.

Bi Yuwei, who used to be able to study alone, now has more than a dozen assistants, plus the Blue Earth Organization's almost highest priority material supply, she is simply at home here. Oh no, I think it's a lot of fun in the lab.

Of course, originally Bi Yuwei could only play with some relatively low toys. After all, she knew limited knowledge, and she didn't know how to make many tall toys.

But now it's different.

The knowledge stored in the central computer on the Jinwu 6 opened her eyes.

As a colonial ship, a central computer stores all kinds of knowledge. However, due to the disappearance of the first bridge, many key technologies have been lost in the central computer of the secondary bridge, such as shipbuilding, nuclear fusion, ion engines and other related technology trees.

But even so, the above knowledge is explosive compared to those who live in the last days.

From planting crops to building rockets from satellites.

Almost all of them.

However, just because you have knowledge doesn't mean you can use it right away.

Human civilization is an industrial civilization, which means that only the corresponding industrial base can explode.

There are no various industrial bases, you play with yarn.

However, the little girl is talented, even if she doesn't have the right materials at hand, she has found a weapon that can be made in a short time, that is, the legendary rich and handsome - electromagnetic cannon.

Tesla, which uses electricity, is more handsome than a Mercedes-Benz that burns oil. Rebuttals are not accepted.

Gasoline, six or seven yuan a liter, has a pungent smell and is flammable. Extensions - incendiary bombs, petrol bombs, flame guns. The bar is too low.

Electricity, formless and insubstantial. It can be turned into electromagnetic waves, hidden in everything, or it can be turned into thunder and lightning, and above the nine heavens, tearing the void. And its extensions are - electromagnetic guns, magnetic guns, lightning storms. Look how high the force is.

So for a long time, electricity has always been full of mystery and elegance in people's minds. And the electromagnetic gun, which is related to electricity as soon as you hear it, is not high!

Although the electromagnetic cannon may seem very tall, in principle, it is even simpler than conventional weapons that rely on chemical energy to propel.

One of the most important aspects of conventional gunpowder weapons that use chemical energy to propel is the manufacture of gunpowder. The various chemical principles involved in it are so complex that they explode! There are countless tech trees to climb.

And in the whole West End, where to find a chemical plant that can make gunpowder?

Without a chemical plant, you simply can't make the various chemicals that produce flames. Therefore, for Lin Chen, it is difficult to ignite the technology tree of gunpowder weapons!

But the electromagnetic cannon is different, the electromagnetic cannon is a magnetic energy weapon that uses electricity to emit, and mainly requires low-resistivity materials and high-energy batteries.

And these two can really be obtained in the West End.

High-energy batteries are everywhere in the West End, as long as you find a few electric cars and remove the high-energy batteries inside, you may be able to find a few good batteries that have not completely failed.

Even if you don't have a good battery, it doesn't matter. Lin Chen's repair skills are up, how many batteries do you need, how many batteries do you need.

As for low-resistance materials, there are a whole bunch of them on electric vehicles. After all, it is a car that is powered by electricity, and many of the materials used on it, especially the motor that drives the car, require low resistivity materials.

With the materials in hand, Bi Yuwei and his team of engineers worked on the map and finally completed the construction of the prototype gun in two weeks.

On the first day of the test launch, Bi Yuwei specially asked someone to notify Lin Chen to come and watch.

Seeing Dao Lin Chen coming, Bi Yuwei immediately happily pointed to a big guy and said:

"Lin Chen, look, look, this is the electromagnetic cannon we made! Handsome or not! ”

Following the direction of Bi Yuwei's pointing, Lin Chen soon saw a big guy with an extremely ugly appearance.

Can this thing be called handsome? Are you sure that the aesthetic is the same as that of ordinary people? Biyuwei?

Looking at this ugly big guy, Lin Chen had to worry about Bi Yuwei's aesthetic sense.

A huge cannon barrel with a length of more than ten meters, followed by a square box, and then hundreds of sets of high-energy battery packs were densely arranged around the perimeter of the box.

Just these three pieces, simple and crude, without any beauty. It's completely forcible to put it together.

I saw a large number of bare wires extending from these high-energy batteries, and then connected to this box, which was full of weld patches and dense patches of various jumpers.

Seeing this strange structure, Lin Chen couldn't help but ask curiously, "This is the electromagnetic cannon you made up?" ”

"Well, the electromagnetic cannon, it's just a prototype, it's a bit big. But let me tell you, don't look at this big guy is rough, but it's very powerful! ”

"It's powerful, how big?" Lin Chen asked curiously.

"It's hard to say, we haven't done formal testing yet. But according to my calculations, the projectile fired by this electromagnetic cannon should be able to reach five times the speed of sound, and the energy generated can reach more than 1.4 million joules... ”

Seeing that the little girl came up, she was covered with N more data splitting her head and face, and Lin Chen immediately asked her to stop!

"Stop, stop, talk to people! Let's shoot right in and see if your new invention is amazing! ”

"Well, good!"

Seeing that Dao Lin Chen wanted to see the power of his new toy, Bi Yuwei immediately commanded her team of engineers to start operating.

I saw only these engineers, who carefully stuffed a black projectile into this square box, and then connected the power supply!

"The first theoretical test launch of the Type I electromagnetic gun begins, and the voltage boost begins!"

"The voltage has reached a critical value, and the countdown to launch begins, ten, nine, eight, seven。。。。。 Three, two, one! ”

"Launch!"

As an engineer pressed the red launch button, he saw a violent spark of electricity surging from the ten-meter-long barrel, and for a moment the entire laboratory flashed and thundered.

Rumble~

In a very short period of time, a black object rushed out of the barrel of the cannon with lightning speed, and then instantly broke through the sound barrier, producing a huge figure like a roar.

Before Lin Chen could react, they heard a series of huge explosions from a distance.

"What's going on?"

The soldier in charge of the escort was startled by the loud roar and rushed in.

"It's okay, it's okay, it's just experimenting. Get out, get out! ”

Lin Chen saw a large group of guards rushing in, and immediately told them to hurry out. This is the laboratory, and most of the guards can only cause chaos when they come in.

Just then, a technician in charge of checking the results of the test shot shouted.

"Oh my God, come and see!"

"What's wrong, what's wrong. Let me see! ”

After speaking, Lin Chen, who took the telescope, looked at the shooting range and immediately gasped.

In the direction they were firing was an abandoned building.

In the middle of the building, which is about 30 stories high, a huge through-hole has appeared.

The thick wall, almost like a thin layer of paper, was blasted through by this electromagnetic cannonball.

I don't know how many times more powerful this power than the most powerful tank main gun in Lin Chen's hand before.

The two are not at all an order of magnitude.

"This power is really emotional! Little girl, you have made another great contribution this time!"

After receiving Lin Chen's praise, Bi Yuwei immediately narrowed her eyes and was very happy.

But at this moment, the electromagnetic cannon that had just completed its first kill suddenly flashed with a burst of electric sparks and shut down.

"Ah, that's how it is."

Seeing his new invention, it was only used once, and then it went out. The little girl suddenly languished.

Seeing him like this, Lin Chen not only laughed.

"Alright, alright, it's okay. This is the prototype electromagnetic cannon you made. I believe that as long as you lead the team to continue to optimize and transform, you will definitely be able to come up with a more perfect plan! ”

"But, but, this is the best material we can find. If even this material can't withstand instantaneous ultra-high pressure, then this weapon has no real combat value at all. Could it be that Lin Chen wants to shoot a cannon and change the barrel? ”

Hearing Bi Yuwei's words, Lin Chen was suddenly a little stunned.

In his mind, an exaggerated vision conjured up. A super-large caliber electromagnetic cannon was installed on his flagship, and as long as the button was pressed, the electromagnetic cannon shell thicker than a bucket was immediately shot out. Then the enemy in front of him was instantly wiped out.

But the herd of beasts is simply endless, and I killed an unknown number of insects and beasts with one shot, and then more insects and beasts poured over. And he actually led someone to change the barrel, which is really embarrassing.

Lin Chen, who came back to his senses, immediately asked, "Ah! Biyuwei, this is indeed a big problem, and we need to solve it right away! What kind of materials do you need, tell me and I'll do it for you! ”

"Really? Great, I knew Lin Chen, you have a way! ”

"I want a high-temperature superconductor, the kind that has zero absolute resistance, well, it must be zero, there can't be any resistance value, and it can withstand a high-temperature environment at the same time!"

What, high-temperature superconductors!

Does this thing really exist? Hearing Bi Yuwei's words, Lin Chen was stunned.
