"Thorny ......"

A dazzling electric light flashed, and a huge discharge phenomenon was produced between the two copper guide rails, and the current continued to penetrate the air, and the hot plasma jumped between the copper guide rails, and in the blink of an eye, the guide rails were melted into a ball of copper water.

It was only at this point that the crossbow machine ejected the copper pillar. The long-overdue copper pillar plunged into the copper water in a red state, and under the action of the plasma, it also quickly turned red and melted, and it was no longer distinguishable from the guide rail.

Chen Zheng hurriedly threw the burned electromagnetic cannon on the ground, the hot copper juice scalded the snow, and the stagnant water quickly overflowed the copper juice, and the snow pit suddenly sounded with a boiling sound, and a large area of water vapor came out, and then was blown by the cold wind into a white ice mist that slowly rose with the heat.

“……”

Chen Zheng stood silently to the side, waiting for the boiling sound to fade away, and reached out to fish out his electromagnetic cannon from the warm snow water.

The brass rails nailed to the crossbow machine had turned into a melted and solidified candle, and the wood underneath had been scalded to the point of charring fire, and was still emitting water vapor and smoke when it was fished out.

An unhappy Chen Zheng removed the red copper that had melted into a strange shape and threw it into the basket next to him, making a clanging metal crash - the wooden basket already contained many similar molten copper pieces.

"Alas......"

Chen Zheng sighed.

He failed again.

The reason for the failure was not that the voltage and current were too low and the power of the electromagnetic cannon was insufficient, but on the contrary, his troubles came from the excessive voltage and current.

The huge energy instantly pierced the air, and was released like lightning in less than a tenth of a second, creating a high temperature of more than 3,000 degrees in addition to dazzling flashes.

At such temperatures, red copper melts into copper as easily as a candle.

Theoretically, as long as the voltage and current are sufficient, the power of the electromagnetic railgun will increase infinitely...... But Chen Zheng dared to say that even the electromagnetic railgun on the earth, which has become practical, has never taken into account the discharge phenomenon between the rails.

Chen Zheng vaguely remembered that when the voltage was 10,000 volts, the air would be easily penetrated, so it seemed that the voltage used by the electromagnetic railgun on the earth should not exceed 10,000 volts.

The technology they employed was a strategy of "low" voltage and "high" current, using an unidentified current of around 40 megawatts to drive an electromagnetic gun to accelerate the projectile to more than 2,000 meters per second, and the kinetic energy could allegedly reach 20 to 30 megajoules.

Modern tank guns can accelerate the tungsten core rod similar to the shape of a long arrow to more than 1,700 m/s when firing tail stabilized shell-piercing shells, the muzzle kinetic energy reaches more than 11 megajoules, and the armor-piercing capacity for homogeneous armor is between 800 and 1000 mm.

After referring to the power of the tank gun, if the data of the electromagnetic cannon is converted, and the performance problem of the core is removed, the armor-piercing ability of the existing electromagnetic gun on the earth is about 1600 to 3000 mm.

In this way, as long as Chen Zheng can create an electromagnetic railgun with similar power to the earth, there is hope to penetrate Roshan's armor......

But in fact, considering that Chen Zheng's projectile material is soft red copper, and the performance of red copper is compared with the performance of tungsten alloy or depleted uranium alloy material...... Then this armor-piercing ability will be greatly reduced.

This is one of the reasons why Chen Zheng maintains ultra-high voltage. As for another reason...... It's because Chen Zheng wants to save materials.

If the voltage is reduced, Chen Zheng needs to make slightly low-cost ions, and the electrical energy contained in the "low" valence ions is greatly reduced, and if you want to get the necessary current, you need several times or even dozens of times the strange fish crystal.

In this way, the consumption of Strange Fish Crystals becomes unacceptable.

So should you put some kind of insulator between the rails?

Generally speaking, an insulator is a substance that has no free electrons, but when the voltage is high to a certain level, the non-free electrons will also be forcibly stripped out, and the insulator will be "broken down".

In order to solve the problem of ultra-high voltage breakdown, it is necessary to increase the difficulty of non-free electrons being stripped out.

Enhance the attraction of molecules to electrons?

With the development of modern science and technology, the inside of the atom can only be destroyed but not built. Therefore, the only way to enhance the attraction of electrons is to study special compounds and use special molecular structures to strengthen their ability to bind electrons.

Although there is a direction - insulated ceramics - this road is a dead end for Chen Zheng.

Not to mention that he doesn't understand molecular materials, even if he does, he can't make this special ceramic without equipment, assistants, and most importantly, without a few years or even more than ten years.

So, he had to think differently.

Chen Zheng absentmindedly played with the blackened crossbow machine.

Suddenly, he froze.

A few times before, Chen Zheng casually threw the carbonized crossbow machine into the fire, and did not carefully observe the carbonized crossbow machine.

And this time, he finally discovered the anomaly on the crossbow machine - on a piece of charred black carbonized wooden crossbow machine, the wood that had not been carbonized caught Chen Zheng's attention.

These parts that are not carbonized have a strange shape, like ...... Chen Zheng's handprint is the same!

After thinking carefully about the posture he had held the crossbow in before, Chen Zheng raised the crossbow again, and then checked the place where he was holding it......

…… Really!

The white uncarbonized traces were indeed the handprints left by Chen Zheng when he held the crossbow machine before!

Why is this happening?

Chen Zheng thought about it, and after ruling out all other possibilities, the remaining answer was ......

Chen Zheng was suddenly stunned.

That's right!

The human body is also a conductor! Why didn't the arc climb to Chen Zheng's hands!?

Thinking like this, Chen Zheng's hands gradually lit up with a pale blue glow.

Is it because of this?

This pale blue halo was produced when the zero force was released, and it was precisely the wonderful reaction between it and the strange fish crystal that allowed Chen Zheng to make any matter within the scope of his knowledge at will.

However, although Chen Zheng was already relatively proficient in the use of Zero Force, Chen Zheng still did not know much about this power.

Zero Force ...... Can it be insulated?

Thinking like this, Chen Zheng picked up the spare crossbow machine, re-pulled out a copper pillar and put it on the crossbow machine, his left hand flashed with a faint light, wrapped the copper rail into it, and pulled the trigger again at the big tree in the distance.

"Whoosh......"

The powder of the Strange Fish Crystal was instantly transformed into ultra-high valence ions under the action of zero force, and the majestic energy flowed along the wires to the two copper guide rails.

This time, due to the pale blue light, the air between the copper rails was not broken through until the copper pillar plunged headlong into the rails......

"Hum—"

"Poof—"

The copper pillar bloomed with dazzling light, and was instantly accelerated to the limit, turning into a light mark and flying straight into the distance!

Chen Zheng only felt a majestic thrust coming from the crossbow machine, and before he could react, he was pushed to the ground by this huge force.
