Chapter 272: A Pleasant Surprise
“Actually, in thunderstorm weather, the lower part of the cloud layer carries a large amount of negative charge. The clouds carry water droplets and dust particles, and ice crystals stirred by the wind will rub against each other to produce huge electric charge!”
“Among them, the positive charge will sink, and the negative charge will rise to the top. When the positive and negative charges separate to a certain intensity and the electric power is strong enough, intense discharge occurs! That’s the lightning in the sky we just saw!”
“At the same time, when this lightning streaks through the air, it rapidly causes expansion with the surrounding air. The process of expansion compressing the air produces a shock wave, and when it spreads out, it’s the sound of thunder we hear!”
Several people nodded. Commander He also calmed down and listened to her explanation seriously. Miraculously, what she said they could actually understand.
“Trees in high places, rocks, or tall buildings also carry electric charge! When they accumulate to a certain extent, they release, forming lightning of one to ten billion volts. You can imagine what happens to the place struck by lightning.”
“But why does it always strike high places? And it always strikes near me, and even my utensils are all smashed to pieces!” Commander He looked innocent, so angry he wanted to curse!
“Actually, it’s a phenomenon of tip discharge, because the sharp high object is just close to the lightning and more easily absorbs electric charge. Moreover, at this tip, it looks for a conducting conductor, and you are the best one. Your iron, copper, and those utensils are also conductors!”
He had lived here for so long and still survived, which was a heavenly miracle of luck!
It also honed his skill of quick evasion!
“Thunder Needle, what is that?”
That was his point of concern.
“As the name implies, it’s a divine artifact to avoid being struck by lightning!”
“It can prevent me and the things around this place from being struck by lightning?”
“Exactly!” Li Xi’er said confidently, but her body didn’t move at all.
Commander He swallowed some saliva, his eyes gleaming as he flattered: “Hehe, alright then. If you can help me make this Thunder Needle, I’ll help you with that favor you need! Deal?”
Li Xi’er and Feng Qingcheng exchanged an understanding glance and nodded lightly: “Alright!”
“However, can you actually make the thing I want?” She also raised her doubt!
“Don’t underestimate me, young brother! Hehe! This friend, may I ask, what specific kind of thing?”
“Here, this one!”
Li Xi’er first handed him the black tungsten ore in her hand.
The man took it and examined it for a while, “Black stone?”
“You know it?”
“Mm, I picked one up before and studied it! What do you want to use it for?” His beard like dry grass, puzzled gaze.
He had chiseled this black stone back to study; it wasn’t ordinarily hard!
Li Xi’er looked up and pointed at a flash of lightning in the sky, “Did you see the light emitted by that lightning just now? I want to capture it and use it for long-term lighting!”
“What?”
Commander He was stunned, then looked at her and suddenly burst into loud laughter, throwing his head back!
Finally, someone in this world had the same idea as him?
It was just that this young brother was even crazier than him. Could this broken stone collect lightning light?
Seeing his young face full of eager curiosity, it was so cute, haha!
After all this time, it turned out this little guy was a like-minded friend of his!
Rare, rare! What a surprise!
Commander He was overjoyed and excitedly hugged her, lifted her up and spun her around, patting her back like treating a child, shaking her!
“Haha, heaven has eyes!”
Suddenly he straightened her up, his eyes wide open: “But… young brother, how did you suddenly think of using this thing to capture the lightning in the sky?”
“To be honest, every time I use utensils to collect this lightning, those objects get burned! The ground gets pitted too!”
He would dodge to the side to watch!
No wonder, as soon as Li Xi’er arrived, she saw the crooked, cracked iron sheet pouches! There were big pits on the ground too!
It wasn’t lightning striking unintentionally, but him intentionally collecting it!
Feng Qingcheng’s face turned iron-blue, clenching his fist. He never expected this person to act so fast, daring to suddenly hug her and spin her around?
If not for needing to use him, he would almost want to finish him off with one sword!
Humph!
Li Xi’er touched her dizzy head, a stench rushing straight to her forehead, almost making her faint!
Covering her nose, she sighed inwardly! This guy was all about research, stinking all over, who knows how long since he last washed!
“Are you stupid? Why use utensils to collect it? You’re lucky it didn’t strike you into black charcoal!”
“Then this black stone… could it really collect the flash?” How exactly to collect it?
Thinking of this, he picked it up and prepared to place it on the ground on the stone in the highest place to try! “Like this?”
He was long past caring about his own life and death!
“Hey! Wait!”
Li Xi’er took it over, “Not in that sense, not using it to collect. I mean it’s a carrier, a heating element, an object that can convert energy into light! Understand?”
Commander He stared with big eyes, listening seriously, “Mm, go on!”
“I want to turn this tungsten ore into pure tungsten, then into thin tungsten filament. Then this tungsten filament will connect to my utensil.”
“See this small light bulb? It will be its filament, and then it can continuously emit light like the lightning just now for lighting!”
Li Xi’er had Bu Wei bring her small generator for him to see. He quickly understood this physical principle.
Seeing that light bulb made of glazed ware, he fondled it delightedly, unable to put it down!
After she finished explaining, without a doubt, it immediately piqued his interest. “I have a request. After making the tungsten filament, can I personally watch the process of it conducting electricity?”
“No problem!”
At this moment, no need for her to say more. He was already holding that tungsten stone like a treasure, going off to study grinding it into powder and purifying it!
The utensil for grinding powder was that spiral iron utensil she saw when she arrived earlier.
He went to grind powder, and she focused on making the Thunder Needle! It was raining now.
“Hey, be careful!”
Li Xi’er shouted to the distance, worriedly instructing him!
“No problem, this little rain is nothing! I wasn’t afraid of it in battle, afraid of this?”
Li Xi’er shook her head speechlessly!
“Then first help me find some materials. Do you have any needle-shaped pointed conductors here, copper or iron, either works!”
“Will a needle do?”
“I’ll try!”
Commander He found some things and busied himself there regardless. She, Feng Qingcheng, and Bu Wei took shelter under the cliff face where that person lived!
She put away the small generator, protecting it from getting wet by the rain.
She lit a fire and began designing her lightning protection device!
