"Thuh..."

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

It was not until this time that the crossbow ejected the copper column. The long-awaited copper column plunged into the red-roasted copper water, and under the action of plasma, it also turned red and melted, and could no longer be separated from the guide rail.

Chen Zheng quickly threw the burned electromagnetic rail cannon on the ground. The hot copper juice curled the snow, and the accumulated water quickly overflowed the copper juice. The boiling sound suddenly sounded in the entire snow pit. Large pieces of water vapor came out, and then the cold wind turned into pieces of white ice fog and slowly rose.

“…”

Chen Zheng stood aside silently, waiting for the boiling sound to gradually weaken, and reached out to fish out his electromagnetic cannon from the warm snow water.

The copper guide rails nailed to the crossbow machine have turned into solidified fluid, and the wood below has been burned and carbonized and caught fire. After being fished out, it still emits water vapor and thick smoke.

Chen Zheng, who had an unpleasant face, took off the red copper melted into a strange shape and threw it into the basket next to him, making a jingling sound of metal impact. The wooden basket had already filled a lot of similar molten copper blocks.

"well……"

Chen Zheng sighed.

This time, he failed again.

The reason for the failure is not because the voltage and current is too low. On the contrary, his troubles come from excessive voltage and current - the energy that can penetrate the air instantly is not a joke, it is simply artificial lightning.

The huge energy is released in less than one tenth of a second. In addition to the dazzling flash, there is also a high temperature of more than 3,000 degrees. At such a temperature, the red copper will easily be melted into copper water.

Theoretically, as long as the voltage and current are sufficient, the rate of firing of the electromagnetic railgun will be infinitely increased... But Chen Zheng dares to say that even the electromagnetic railgun that has become more practical on the earth has never considered the resistance problem between the guide rails.

Chen Zheng vaguely remembered that when the voltage is less than 10,000 volts, the resistivity of the air is considered to be approaching infinity, and when it is greater than 10,000 volts, the air is easily broken down and becomes a conductor.

Obviously, the voltage used by electromagnetic railguns on the earth does not exceed 10,000 volts. The technology they used is a strategy of "low" voltage and "high" current, using currents of about 40 megawatts and unknown voltages to drive the electromagnetic gun, accelerating the projectile to more than 2,000 meters per second, and the kinetic energy can reach 20 to 30 megjoules.

When modern tank guns launch a stable shell-out armor-piercing projectile, they can accelerate the tungsten core rod similar to the shape of a long arrow to more than 1,700 meters per second, and the kinetic energy of the muzzle reaches more than 11 megajoules, and the armor-piercing capacity for homogeneous armor is between 800 and 1,000 mm.

After referring to the power of the tank gun and bringing the data of the electromagnetic gun into the conversion, even if the performance problems of the core are eliminated, the existing electromagnetic guns on the earth's armor-piercing capabilities are about 1,600 to 3,000 mm.

It seems that as long as Chen Zheng can create an electromagnetic rail cannon with a power similar to that on Earth, he will have the hope of breaking through the armor of Roshan...

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

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

So far, if you want to lower the voltage, you will create ions in a slightly lower valuation state, and the electrical energy contained in the "low" valuation state is greatly reduced. To get the necessary current, you need more strange fish crystals.

In this way, the number of monster fish crystals consumed for each launch becomes unacceptable.

Chen Zheng must solve the problem of ultra-high pressure breaking through air.

Generally speaking, an insulator refers to a substance without free electrons, but when the voltage reaches a certain level, non-free electrons will be forcibly peeled off, and the insulator will be "break down".

If you want to solve the problem of ultra-high voltage, 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 technology, the internal internal atoms can only be destroyed but cannot be built. Then 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 - insulating ceramic - this path cannot be understood for Chen Zheng.

Not to mention that he doesn't understand molecular materials, even if he knows it, there is no equipment, no assistant, and the most important thing is that he will never be able to make such a special ceramic without a few or even more than ten years.

No, you have to change your mind.

Chen Zheng shook his head and played with the burnt crossbow machine dejectedly.

Suddenly, Chen Zheng was stunned.

A few times before, he threw the carbonized crossbow into the fire, and did not carefully observe the carbonized crossbow.

And this time, he finally discovered the abnormality on the crossbow machine - on a charred and carbonized wooden crossbow machine, the white wood that was not carbonized attracted Chen Zheng's attention.

These uncarbonized woods are very strange in shape, just like... Chen Zheng's handprints!

After carefully thinking about his posture when he held the crossbow before, Chen Zheng raised the crossbow machine again, and then checked the place he held...

……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 for a while and eliminated all possibilities, he suddenly became stunned.

yes!

The human body is also a conductor! Moreover, the breakdown voltage of the human body is much lower than that of air! Chen Zheng's hand is obviously closer to the ultra-high-priced ions he created than to the metal guide rails! Why didn't the arc climb onto Chen Zheng's hand?

Thinking of this, a light blue light gradually lit up on Chen Zheng's hands.

Is it because of this?

This light blue halo is produced when zero force is released. It is precisely its wonderful reaction with the strange fish crystal, which allows Chen Zheng to create any substance within the scope of his knowledge as he wishes.

However, although Chen Zheng is already more skilled in using zero force, Chen Zheng still knows little about this power.

Zero force...can it be insulated?

Thinking of this, Chen Zheng picked up the spare crossbow machine, pulled out a copper pillar again and placed it on the crossbow machine. His left hand shone with a faint light, wrapped the copper rail in, aimed at the big tree in the distance and pulled the trigger again.

"Swoosh..."

The powder of the strange fish crystal instantly transformed into ultra-high-priced ions under the action of zero force, and the majestic energy flowed along the wire to the two copper guide rails. This time, due to the light blue light, the air between the copper rails was not penetrated until the copper pillar plunged into the guide rails...

"Buzz--"

"puff--"
