Fertile land

Chapter 272 There is a surprise

"In fact, during thunderstorms, the lower parts of the clouds have a lot of negative charges. The clouds carry water droplets and dust particles. When the ice crystals are stirred by the wind, they will rub against each other and generate huge charges!"

"The positive charges will sink and the negative charges will rise to the top. When the positive and negative charges are separated to a certain intensity and the electric power is strong enough, a strong discharge will occur! This is the lightning in the sky we just saw!"

"At the same time, when the lightning flashes through the air, it rapidly expands with the surrounding air. The process of expanding and compressing the air will generate shock waves, which spread out and become the sound of thunder we hear!"

Several people nodded, and Commander He calmed down and listened to her explanation carefully. Miraculously, they could understand what she said.

"The high trees, rocks or tall buildings are also charged! When they gather to a certain extent, they will be released to form one to one billion volts of lightning. You can imagine what will happen to the place struck by lightning. Sample."

"But why does it always hit high places? It always hits near me, and all my utensils were beaten to pieces!" Commander He looked innocent and wanted to curse!
"In fact, it is a phenomenon of tip discharge, because the tip of the tall object is close to the lightning and is easier to absorb the charge, and it is looking for a conductor at the tip, and you are the best conductor. Those iron, copper and other utensils are also conductors!"

He has lived here for so long, and it is a huge miracle that he is still alive!

He also developed his ability to dodge quickly!
"Thunderbolt needle, what is that?"

This is his focus.

"As the name suggests, it needs a magical weapon to avoid being struck by lightning!"

"Does it protect me and everything around my place from being struck by lightning?"

"That's right!" Li Xi'er was certain, but her body didn't move at all.

Commander He swallowed his saliva, his eyes flashed, and he flattered: "Haha, then, if you can help me make this thunder needle, I will help you with the favor! Is it possible?"

Li Xi'er and Feng Qingcheng looked at each other clearly and nodded lightly: "Okay!"

"But, can you make what I want?" She also raised her doubts!
"You kid, don't look down on others! Haha! My friend, may I ask, what is it about?"

"No, this is it!"

Li Xier handed him the black tungsten ore first.

The man looked at it for a while, "Wushi?"

"You recognize it?"

"Well, I picked it up once before and came back to study it! What are you going to use it for?" A beard like withered grass and a puzzled look.

He chiseled this black stone back and studied it. It is not ordinary hard!
Li Xi'er raised her head and pointed at a flash of lightning in the sky, "Did you see the light from that lightning just now? I want to keep it and use it to illuminate it for a long time!"

"what?"

Commander He was stunned for a moment, then looked at her, and suddenly burst into laughter!

Has anyone in this world finally had the same idea as him?

However, this kid is even crazier than him. What kind of lightning can this broken stone collect?

Looking at his eagerness for knowledge at such a young age, he is so cute, haha!
After working on it for a long time, it turned out that this little guy was still his like-minded friend!

Rare! Rare! Surprise, surprise!

Commander He hugged her with joy and excitement, picked her up and spun her around, patted her back and shook her like a child!
"Haha, God has eyes!"

Suddenly he corrected her again, his eyes widened: "But... little brother, why did you suddenly think of using this thing to keep the lightning in the sky?" "To be honest, this lightning, every day The first time I tried to collect it with a tool, the objects were burned! There were holes on the ground!"

He hid and watched!
No wonder, when Li Xier arrived, she saw a pocket-shaped iron sheet like a crooked melon and a cracked jujube! There is a big hole in the ground!

Not only were the lightning struck accidentally, but he collected them intentionally!

Feng Qingcheng's face turned livid and she clenched her fists. He never expected that this person would move so fast and dare to hug her and spin her around all of a sudden?
If it wasn't for the sake of using him, I would have killed him with a sword!
snort!
Li Xi'er touched her dizzy head, and a stench went straight to her forehead, and she almost fainted!

I covered my nose and sighed secretly! This guy is so focused on research that he stinks all over, and he hasn’t washed up in an unknown amount of time!

"You are stupid, what are you doing to collect it with a tool? It's all good if it doesn't beat you into black charcoal!"

"Then this black stone...can it really collect light?" How to collect it specifically?
Thinking of this, I picked it up and prepared to place it on the ground on the highest stone to give it a try! "Is it this way?"

He has long ignored his life and death!

"Hey! Wait!"

Li Xi'er took it and said, "That's not what I mean. I didn't collect it. What I mean is that it is a carrier, a heating element, an object that can convert energy into bright light! Do you understand?"

Commander He opened his eyes wide and listened carefully, "Well, keep talking!"

"I want to turn this piece of tungsten ore into pure tungsten, and then turn it into a thin tungsten wire. When the time comes, this tungsten wire will be linked to my device."

"Did you see this little light bulb? It is used as its wick. When the time comes, it will continue to emit the same bright light as lightning just now for lighting!"

Li Xier asked Buwei to show him her small generator, and he quickly understood the physical principles.

When he saw the light bulb made of colored glass, he couldn't put it down and touched it with joy!
When she finished speaking, there was no doubt that she immediately aroused his interest, "I have a request. When it is made into tungsten wire, can you let me see the electrification process with my own eyes?"

"no problem!"

She didn't need to say anything else at this moment. He was already holding the tungsten stone like a treasure to study grinding and purifying it!

The equipment for grinding powder was the spiral iron thing she saw when she came here just now.

While he grinds the powder, she focuses on making thunder needles! It will already start raining.

"Hey, please be safe!"

Li Xi'er shouted in the distance and told him uneasily!
"It's okay, this little bit of rain is nothing! I'm not afraid of war. Are you afraid of it?"

Li Xier shook her head speechlessly!

"Then help me find materials first. Do you have any needle-like pointed conductors? Any copper or iron ones will do!"

"Can a needle be used?"

"Let me try!"

After Commander Na He found something, he didn't care where he was messing around. She and Feng Qingcheng didn't want to hide under the cliff where that man lived!
Place the small generator and protect it from rain.

Light a fire and start designing her lightning protection device!
