my stealth fighter

Chapter 311 Million Volts
The two sides of the artificial lake are separated by tens of meters. With such a distance, the red dot of the laser sight is not very obvious. Fortunately, there is no one there, and it will be fine even if you shoot it crookedly.

Zixuan said: "In the future, the sight can be replaced with a more advanced camera device, and the captured images can be transmitted to the special glasses. After wearing the glasses, you can see where you are aiming. Otherwise, you will not be able to see if you are too far away. It's red dot."

Jiang Chanji thought of the monocular combat power detector of the Saiyans for no reason. It must be very handsome to make such glasses.

Wang Yefei roughly aimed at a willow tree, held the handle, and activated the ability.

A current flows from the iron-cobalt alloy of the handle to the anode inside the laser cannon.

A discharge is instantaneously generated between the high voltage at the anode and the cathode.

Nitrogen, helium and carbon dioxide are mixed in the discharge tube. The nitrogen molecules are excited by the impact of electrons, and then collide with the carbon dioxide molecules, transferring energy to the carbon dioxide molecules. The carbon dioxide molecules jump from a low energy level to a high energy level. Inverted, bursting with bright light.

The scattered strong light is gathered into a beam by the reflector, and shoots out from the glass hole on the front of the laser cannon.

There are no gorgeous light and shadow effects, because the carbon dioxide laser is in the mid-infrared band, invisible to the naked eye, and there is not even the slightest sound. No one knows whether Wang Yefei fired the laser or not.

Suddenly, blue smoke and orange flames rose from the trunk of the willow tree opposite the artificial lake, and then burst into flames.

"Quick! It's on fire! Put out the fire!"

Qianyang hurriedly called the guards and staff at home. These people were also puzzled when they saw the willow tree on fire for no reason, but they didn't ask too much.

Wang Yefei had already put down the laser cannon, and she could feel the temperature of the laser cannon shell rising sharply, even to the point of being hot, and the temperature inside the laser cannon could be imagined.

The cooling water circulation system starts to work automatically, and the heat inside the laser cannon is brought out through the flowing water to exchange heat with the outside air, but cooling down in this way is definitely slower.

"Sister Xiaosui, can you make the water flow faster?" Zixuan asked.

The cooling water circulation system has a built-in battery, but limited by its size and weight, it is similar to a toy. After Qianyang is able to control the ability skillfully, the battery will be removed to further reduce the weight and volume, but now Qianyang is not precise enough to control the ability. The big one burned the circulator down.

"Okay, it's a piece of cake." Xiaosui accelerated the water cycle.

"Sister Aurora..." Zixuan looked at Aurora.

"no problem."

Aurora precisely controlled her own ability, the temperature of the circulating water dropped rapidly, almost reaching the freezing point, and it circulated back and forth inside the laser cannon, heating the deep inside, and then cooling down at the position close to the outer shell.

Zixuan silently counted the time.

It took about half a minute for a small indicator light on the cylinder to turn from red to green, indicating that the temperature inside the laser cannon had cooled enough for another shot.

In other words, even with the assistance of Aurora and Xiaosui, the user needs at least half a minute before firing the second laser beam.

Considering the proficiency of cooperation in the future and the further improvement of the internal parts of the laser cannon, the interval time is expected to be further shortened, but it is not bad to be able to shorten it by a few seconds.

If only relying on the cooling device of the laser cannon itself, I am afraid that only one beam of laser can be fired in the whole battle.

"Mr. Wang, how do you feel?" Zixuan asked.

Wang Yefei was speechless for a while, and then sighed after a while, "Amazing!"

Isn't this kind of long-distance attack ability of pointing where to hit is the dream of all electricity-type ability users?

"But the power doesn't seem to be enough..." Zi Xuan frowned and looked at the other side.

The fire on the willow tree has been extinguished, and Qianyang asked the staff to leave the fire extinguisher and leave.

Everyone ran to the other side and stood by the willow tree to observe the marks left by the laser burn.

The green willow tree that was sprouting and taking leaves has turned into a tree of pear blossoms and crabapple trees, as if covered with snow. This is because the foam fire extinguisher has sprayed it from top to bottom. Even now that the staff has left, the foam is still pattering. Lili flowed down the branches and trunks.

At the chest height of the tree trunk, a nearly circular hole appeared, the thickness of a finger, and the inside and outside of the hole were scorched black, and the other end could be seen from one end.

The fire spread from the hole to the whole tree.

Just looking at this hole, one might feel that the power is nothing more than that, not as destructive as the arrows shot by the Screaming Bone Bow, and even less powerful than the sweeping momentum of the Horn Bow. But in fact, as long as the laser is shot, there is no way to hide. The best chance is that as long as the target is aimed and the electric energy is released before shooting, the hit target will almost certainly die without special protection...

The laser landing point will rise to a high temperature of hundreds, thousands or even tens of thousands of degrees in a short period of time, which is enough to melt the steel. As for how short the time is, it depends on the power of the laser. It is said that this is the strongest point of destruction Weapons are not too much.

Not only was the tree trunk burned with a hole, but even the courtyard wall behind the tree trunk was scorched black.

Everyone was stunned. If the laser beam landed on the human body, a hole would be burned out in the human body, but no bleeding would occur, because the blood vessels where the laser landed had been scorched.

"Mr. Wang, did you give your best just now?" Zixuan asked.

"No, I used about half of my ability." Wang Yefei shook her head. When facing an unfamiliar weapon, no one would come up and use all her strength. To put it bluntly, what if the laser cannon can't bear it?
Zixuan visually measured the distance of the artificial lake, and estimated the burning effect and time of the laser on the tree trunk, because the power of the laser is inversely proportional to the distance of use, the farther the distance, the more serious the loss of the laser caused by air, water vapor, and dust .

"This time the power is about 2kw to 3kw." She said, "Mr. Wang, please try again, this time with all your strength."

"it is good."

Everyone returned to their original positions, and Wang Yefei picked up the laser cannon again. This time, she and everyone were mentally prepared. She aimed at another tree and activated the ability.

The electrical energy is converted into light energy again, and a straight beam invisible to the naked eye hits the target.

Just shooting a hole in a tree is no longer a challenge. Wang Yefei used all his strength this time to make the laser last a few seconds longer, and moved her hand slightly.

Click.

The willow tree with the thickness of an adult woman's thigh not only caught fire, but also broke in the middle, and the upper half fell to the ground together with the crown.

In the past, when Wang Yefei released electric energy, he often only released it for a moment. The same is true for other electric supernatural beings, because the electric department is different from other departments. To make the target lose the ability to resist, they will either be electrocuted to death, or they will be unable to take care of themselves. Why must the target be made into fried chicken to stop?

Because of this, the power of an electric transcendent is very strong, but the sustaining power is very poor. She used it for a few seconds this time, and she was more tired than using the ability a dozen times in a short period of time.

And after a few seconds, the heat inside the laser cannon came out, and the entire metal cylinder was so hot that it could only be placed on the ground to let it cool down slowly, and it was impossible to hold it.

Everyone didn't care about anything else, so they picked up the fire extinguisher and put out the fire quickly to prevent the fire from spreading.

When the fire was extinguished, everyone saw that the section of the trunk had been scorched, but it could still be seen that the section was neat, like tofu cut by a scalpel.

"It's almost 5kw this time, just a rough estimate." Zixuan said, then turned to look at Qianyang, "Senior Qianyang, it's time for you to try."

"Uh... okay." Qianyang stood in front of the laser cannon without confidence.

Xiaosui and Aurora cooled down the laser cannon first, and when the temperature dropped, Qianyang carried it on his shoulders like Wang Yefei, and turned to ask everyone if they had any questions, but she was speechless after seeing her.

"Hey! Why did you all run so far?" She cried out dissatisfied.

Except for the grandfather who was sitting in the wheelchair and Wang Yefei who was teaching by example, everyone, including Xiaosui, hid far away, using the courtyard walls and buildings to cover their bodies, and only poked their heads out to look at this side.

"No, no, we are just afraid of affecting you..." Xiaosui laughed awkwardly.

"Yes, yes, it will be fine if you get distracted." Jiang Chanji echoed.

I don’t blame everyone for running away. It’s because Qianyang doesn’t seem as reassuring as Wang Yefei. The latter has been immersed in electrical abilities for many years and is an experienced teacher. …But Qianyang’s theoretically able to release electric energy is amazingly strong, just like a nuclear bomb launcher and password are mastered by a child who doesn’t understand anything, everyone is beating their hearts, watching her bend down to pick up the laser cannon, Everyone ran away at the same time...

"You liars!" Qianyang said angrily, "Is that why you don't trust me?"

"No, no, it's not that I'm worried about you, it's just...to be on the safe side." Jiang Chanji explained.

"Hmph! I know who you are!" Qian Yang asked her grandfather for help, "Grandpa, look at them..."

Grandpa laughed and said, "Actually, I want to run too, but I can't..."

"Grandpa! Why are you like them!" Qianyang blushed with anger.

After making a joke, Qianyang pouted and pointed the laser cannon at the willow tree on the other side of the artificial lake, with Wang Yefei escorting him to avoid accidents.

"Sister Qianyang, Teacher Wang has already tried the tree, so don't try it, just aim at the stone by the lake." Zixuan shouted.

"Oh." Qianyang adjusted the pointing of the muzzle according to his words, and the red dot of the sight fell on the stone on the other side of the lake.

She calmed down, put the joke aside, and concentrated on the handle of the iron-cobalt alloy. The electrons inside the alloy were pulled by her bioelectricity and began to move according to her will.

A current similar to the one just now but with a much higher intensity poured into the laser cannon. The strong voltage caused the carbon dioxide molecules to jump to a high energy level, the number of particles reversed, and the invisible laser light was transmitted from the circular hole again.

However, after all, Qianyang is a young lady who can't lift her shoulders or hands. She has never carried such a heavy object on her shoulders. Although it is no problem to carry it, due to nervousness, the laser cannon slipped a little, just a little bit. , but a distance of tens of meters is enough to cause a large shift in the laser's landing point.

The laser first swept across the lake and then landed on the courtyard wall.

A jaw-dropping scene appeared, the lake that was swept briefly boiled like a pot, the bricks where the laser landed suddenly became white hot, while the adjacent bricks became red and burst out. Bursts of blue smoke.

Qianyang was taken aback. Seeing that the laser cannon was about to fall off her shoulder, Wang Yefei quickly hugged the cylinder with both hands.

"Ah! It's so hot!"

Wang Yefei grinned from the heat, but she still gritted her teeth and insisted on putting the laser cannon safely on the ground before letting go.

"Teacher Wang, are you okay?" Qianyang was startled and regretful, and stretched her neck to check Wang Yefei's injury.

Wang Yefei's palms were reddened by the heat, and some places seemed to be blistered.

"I'm sorry, Mr. Wang, it's all my fault... Do you want to go to the hospital?" Qianyang hurriedly apologized at a loss.

"It's all right, do you have any scalding ointment or something? Rinse it with cold water, and just deal with it briefly." Wang Yefei is not that delicate, and she doesn't take this injury to heart. After returning to school, just ask Lu Weijing to take care of it. She was more concerned about the killing effect of Qianyang's blow just now, because the temperature of the cylinder after the laser cannon was fired was much higher than when she used it.

Everyone ran from the hiding place to the opposite side of the lake and carefully inspected the condition of the courtyard wall.

"What... what's going on here?" Xiaosui asked in surprise.

Everyone could see clearly just now that after the laser landed on the courtyard wall, the masonry where it landed gave off a dazzling white light. As Qianyang stopped releasing his ability, the white light disappeared, but in such a short time, the masonry hit had already disappeared. It is close to a molten state, and now the hot bricks are cooling slowly, and no one dares to touch them with their hands.

What surprised everyone the most was that after the temperature of the masonry dropped, it did not return to its original shape, but showed a translucent state.

Zixuan observed for a while, and said: "The masonry has been vitrified under high temperature. The laser energy just now should be around 10kw, which is enough to cut metal, and it is already considered a weapon-grade category... What restricts the further improvement of power is the core device. Laser diodes, that laser tube is industrial grade, it would be great if we could get weapon grade ones, or it would be better if we could customize it.”

She made a simple conversion. For an industrial-grade laser diode, the output power of 100 watts requires a voltage of about 16kv. If the laser energy just now has 10kw, it means that Qianyang released a voltage of more than 1600kv, or It is 160 million volts.

The relationship between the increase of output power and the voltage is not linear, but roughly speaking. In addition, this kind of electro-optic conversion device, even for ordinary light bulbs, the starting voltage at the moment of light is higher than the working voltage. The same is true for the stage tube, so it is probably no problem to calculate the peak voltage at the moment of Qianyang discharge as 200 million volts.
