"All the work must be done without disturbing the fire dragon." The technician has always been curious to kill the dog.

"Why?" Tan Ya asked.

"Because it was alarmed, the dragon could fly."

"Can't even hit the dragon in the air hit the lightning? I can shoot all the arrows." Tan Ya looked disbelieving.

Can you still be demanding that girls who have been playing with dragons since childhood will learn about junior high school objects by themselves?

Wu Chen was speechless: "Because it's not grounded!"

"Hey, you are so strange. You are flying, so how can you get grounded?"

Confirm that it wasn't cute, Wu Chen took a deep breath and then rushed to the leaders of various stations along the line with a pleasant look, saying: "Everyone has seen that the coils under Line 5 are full of coils. In order to prevent accidents, people must be transferred as soon as possible."

"Your Excellency, are you sure this device can kill dragons?" Many people have more suspicions about black technology than awe.

"Confirm." Wu Chen nodded solemnly.

"But there are many stations in the central area surrounded by Line 5. If they all add up, where can we move to? Is there a safety line?"

Only then did Wu Chen think of a very important question: referring to the doctor's design drawings, no matter how long the lightning is, it is impossible to wrap the entire Moscow!

"Theoretically, the potential difference between the top of the discharge and the ground is infinitely large, but in fact the length of the arc will not be infinitely large. It is limited by the power supply power. The calculation method is: arc length (cm) = p (electric power, unit is watts) at the root number 4318x. The premise is that the primary and secondary frequencies are equal and the 'resonant' state is reached. At this time, the arc length will reach the longest and most efficient. If it is not resonant, the arc length will not reach the result of the formula calculation..." Thinking of this, Wu Chen suddenly spoke. "Dr., the power of the nuclear reactor that you supply the magnetic storm coil..."

“900mw.”

"900 MW!" That's 900000000w! The root number is equal to 30000! Multiply by 4318 and equal to 129540 cm, meters!

"An alternating current above 2000v can penetrate the air. Because we usually connect 220v civil electricity, we have to use a boost transformer to 2000v to stimulate lightning. The doctor is directly connected to the nuclear reactor, and the voltage is far more than 2000v. So there is no need to boost..." Wu Chen suddenly realized, "Doctor, you asked us not to evacuate, but to have a bloody battle!"

"Yes, use enough 'food' to attract the entire dragon group into the ball screen 600 meters away from the Telegraph Building." The doctor suddenly clenched his fist.

I'll go!

"But why do you need to lay such a long underground cable?" The length of the main coil has nothing to do with the length of the arc. This is something that Wu Chen couldn't understand.

"In layman's terms, power is proportional to the thickness of the cable. The higher the power, the thicker the cable will be. Otherwise, the copper core will become hot, and the insulation layer will be burned first and the copper core will fuse. Of course, the cable under the Moscow subway is also a copper core. Fortunately, we also know that there is a 'heat conduction' effect."

"The phenomenon of heat being transmitted from part of the system to another part or from one system to another." Wu Chen understood, "The doctor wanted to exchange length for time."

The reason is very simple. If the melting point of copper is 1000c, the time when a 1-meter-long copper wire reaches the melting point is definitely different from that of 1000 meters of copper wire.

"Then Doctor. You probably..."

"100 seconds."

Can you last for a hundred seconds? Wu Chen expressed his doubts!

"The underground cables are the weakest parts, like super long fuses, they must be the first to blow them." The doctor cheered Wu Chen.

But the technical mate who has not only thought with his lower body is unmoved: "Doctor, what should I do if the dragons are not in the air when hunting? "

The doctor smiled, "Great Sag. Do you think lightning is Zeus's spear, throwing it from the clouds to pierce the flying dragon? No. My friend, lightning is just our lovely lighter!"

"Try, fire, machine?" Wu Chen was completely messy.

"You must have not paid attention. When the fire dragon blasts fire, it will first spray two venom from its glands into the air, and then blow it hard! So, if the venom leaves the dragon's mouth, ignite them, and the fire dragon's head will turn into a big bomb and blow itself into the sky!" The doctor's one-eyed eye was blood red.

By the way, was it because the Fire Dragon complained in person to study how to spit fire...

Generally speaking, objects flying in the air without contact are rarely hit by lightning.

However, there are exceptions, such as Wu Chen's white swan.

Because the aircraft is a metal body with static electricity, and the charge is mostly concentrated on the tip and edge of the aircraft, the nose, the trailing edge of the wings and the tail wings and the tips of various radar antennas are the most susceptible to lightning strikes. Of course, the aircraft has considered the problem of lightning strikes at the beginning of its design. The wings and fuselage are equipped with electrostatic dischargers, which can discharge the static electricity accumulated on the surface of the aircraft into the atmosphere, so as to avoid the charge accumulated in the fuselage causing lightning!

With the size of a Fire Dragon, it is certain that it is hit in a dense artificial electric field.

"Hey, old guy, can you guarantee that lightning won't hit us?" Maris asked with a slanted eye. Although the bear knew nothing about these black technologies, he had a keen intuition that was almost like a beast. He obviously smelled the crisis!

"I have some even-super companion here. If not enough, we can also make some simple Faraday cages..." He didn't explain, but everyone began to doubt it as soon as he opened his mouth. What is "some" and "simple"?! Is your mother really your father's? I'll just rub it and go again!

"I'll do it." Wu Chen didn't speak anymore, it was really an insult to his technical geek.

"My white swan can attract the attention of the dragon group." As long as you shoot the dragon to death, the hatred value will instantly explode.

Staring at Wu Chen's expression of change but without regret, a slight fluctuation suddenly flashed in Dr. Scula's eyes, "Thank you."

Let a crazy old scientist say thank you sincerely with an extremely clear gaze. Wu Chen can also be content.

Before that, there is still some preparations to be done.

Returning to the subway station from the underground fortress of the Central Telegraph Bureau, Wu Chen immediately boarded the White Swan.

Claulia, who had been pondering on the road, finally had her final judgment: "30 seconds."

"Is it only 30 seconds..." Dr. Scula's estimate is still too optimistic.

"Or shorter. With human technology, the possibility of defects in copper core wires is extremely high. It is impossible to be as optimistic as the doctor expected."

Crowlia is right. There must be flaws. Otherwise, human industrial creations would not have the "refundable rate".

"What are we going to do?" Wu Chen thought for a while.

"Put a layer of electrostatic shielding on the white swan." t160 and Crowlia spoke in unison.

The shell of a conductor plays a "protect" role in its interior, making its interior free from external electric fields. This phenomenon is called electrostatic shielding.

The so-called equipotential voltage equalization suit is a safety protective suit made of metal wire using the electrostatic shielding characteristics. It is necessary to wear when operating with charged high voltage. The Faraday cage is also a metal cage made of similar principles. Not to mention the materials needed to make these armors, how can you fight against the Fire Dragon when wearing these bulky equipment that is wrapped from head to toe?

So in the doctor's original plan, it was a price that had to be paid for death. That's why he used the word "food".

If Wu Chen was not present, the doctor would never tell the whole plan. In order to vigorously promote his crazy plan, he would use all his ways to cover up the part that had to be sacrificed.

In other words, it was actually because Wu Chen's arrival gave him a better choice, that's all.

He was criticized by the Fire Dragon as a bear. He relied on batteries and nutrient solution every day to prolong his life. Only he knew what his heart was tortured. Wu Chen would not expect him to be a friend who could still play with him.

Wu Chen was actually not very worried that the white swan would leak electricity, because in order to deal with various emergencies, Claria carried out a systematic Cybertron-style transformation and upgrading of the White Swan. Among them, in order to deal with the attacks of thermal weapons such as dead light, Cybertron capacitors were installed on the core circuit. These supercapacitors that were originally installed on Transformers to protect core components and prevent the circuit from burning out due to energy overload and overloading. It is not enough to deal with some lightning.

What Wu Chen was even more worried about was the destruction of more than 2,000 flying dragons on the white swans. He lost the advantage of height and distance. At a low altitude near the ground, even if the white swan's shell was super hard, it was probably inevitable that small trauma such as scratching the paint surface was probably scratched. In Doomsday mode, it is really harder to find a place to repair it than climbing to the sky.

However, things have to be done.

The plot of the savior of the savior who is soft-hearted and full of justice is one of them. What’s more important is that being able to witness this super artificial lightning with one's own eyes is the dream experience of the technician. If there is a terrib who uses speeches instead of sex, this super technology show is a feast that can satisfy the unique taste of the technician.

Therefore, Wu Chen is quite looking forward to this upcoming artificial miracle.

To be on the safe side, Ivan and others still "persuaded" all underground residents within 1,500 meters of the subway line and moved to the safe area.

Everything is ready. Accompanied by the first ray of sunshine that cut through the darkness, the white swan sprayed surging snowflakes and soared upwards.

On the top of Hilton, Tan Ya was holding a dragon egg and eating Haisai, shaking off the snow-covered white swan cockpit like a waterfall, and waved with a smile.

Wu Chen nodded helplessly and responded that this guy killed the female dragon named Natasha. By the way, did she... use dragon slaying instead of sex?

"Search for all targets to find the pheromones of the male dragon." The white swan quickly disappeared, and Wu Chen activated the quantum weak magnetic resonance radar.

"Finished." The target with the biggest difference between the pheromone from the female dragon is obviously the deepest hidden male dragon in the dragon's nest. t160 quickly locks the target. Based on powerful data calculations with quantum, the male dragon body shape on the holographic platform is quickly modeled.

Sure enough, compared to the ordinary female dragon, the male dragon that coiled itself into a ball, not only was it larger in size, sharper in horns and darker in scales. As he breathed, Wu Chen also saw a huge grape bunch of hearts composed of 32 sarcomas. The white swan approached silently, and the male dragon seemed to feel the crisis and suddenly opened his eyes.

t160 immediately hovered off the plane, and everyone held their breath. Fortunately, after a brief stalemate, the dragon slowly closed its eyes again. (To be continued)
