Chapter 273 Smelting and Drawing
In the rainy night, the dancing firelight illuminated her face, "Can, why is this metal plate buried underground?"

Feng Qingcheng watched her quietly and saw that she carefully installed the copper needle on an iron frame, then used copper wire, aluminum wire and other things to make a thick long wire, and connected it to a metal plate, saying that she wanted to Buried underground.

Commander He owned quite a few of these iron, copper, and even aluminum wares.

She probably made it by smelting the ores he usually picked up!

"This is the function of conduction. The needle tip absorbs the electricity that comes into contact with the electrical layer and then transmits it to the iron plate through this wire and then spreads underground, so that you will not be electrocuted!"

"But...if we step on the ground, won't there be electricity under the ground? Will it electrocute people?"

Feng Qingcheng thought about it and stepped on the ground. Speaking of which, is there usually electricity under the ground?
"No, because the soil and water under the ground are very good conductors of electricity. When they come into contact with electricity, they will disperse very quickly and will not have any impact on people."

After she finished making the thunder needle, she looked around and chose a higher place. On the top of the cliff to hide from the rain, Bu Wei flew up and buried the iron plate as required and set up the iron frame. .

Sure enough, after the burial, the open space on the top of the mountain was not struck by lightning once.

Commander He did not jump up to avoid thunder again! To his surprise, a small needle could be of such great use.

He was also very energetic, and he covered the spiral iron shelf with something to keep out the rain.

He mysteriously added some of his special potion and dropped it on the tungsten stone!

Then wait for a moment, grind it into powder, and carefully collect them together with a small broom!
"Haha, Xiao Xi, right?"

"Xiao Xi, you see that this tungsten ore has been ground and purified. You have found the right person. This stone is hard. The equipment I made cannot be found anywhere else. The impurities are filtered out cleanly! "

Normally, he would also use this thing to filter impurities in iron ore and aluminum ore!

Li Xier saw that he had purified the tungsten ore powder very well, so she took it and looked at it. It was very fine particles.

His eyes flickered firmly, "Thank you, Commander He, for your help. Now I'm just thinking about how to make it into tungsten wire!"

"Tungsten wire? What a joke!"

"Well, my requirements are quite strict. I need very thin tungsten wire, the kind that looks like a feather!"

Commander He hesitated, are you very careful?
"Ahem...no problem!"

Tungsten wire is nothing more than melting the purified tungsten ore powder and then making it into wire!
Making silk requires drawing skills. Well, he can solve this problem, but his requirements are so high, how can he do it?
"Actually, Xiao Xi, I have a question. As long as there is tungsten filament in your light bulb, why does it need to be so thin?"

While they were not paying attention, he secretly scratched the back of his head anxiously!

This is not superfluous. Drawing wire is already enough to test him, but to have it as thin as a feather is too troublesome!

"This will have better conductivity, uniformity, and beauty!"

"Okay, trust me!"

Commander He waved his sleeves and vowed that this Xiao Xi knew more than him. Thinking of the generator just now, he couldn't let him doubt his ability. He had to let him play with him!

It's a pity that I met someone who is more demanding and meticulous than him!
Now, his smelting furnace was about to be used. He calmly led the three of them to a cave next to the cliff. There was actually a cave inside!

This turned out to be a smelting place, with large boilers placed inside, bottles and cans placed in small holes in the mountain, and some operating equipment on the large wooden shelves. She saw the drawing abrasive tool at a glance!
I don’t know what kind of thread he usually pulls with this? It might be iron wire or copper wire, otherwise where did the wires in the wire she just made come from?
As well as various knives made by him, as well as battle axes, a row of hammers of different sizes, some good and some damaged!

There are two or three stone pits on the ground on the side, and there are large stone slabs on the side. Groundwater flows through the stone pits, which is really unique and eye-opening. No wonder he doesn't go back. This place is perfect for refining things. Where can I find such suitable ones elsewhere?

He lit the fire in the boiler, and it probably burned to nearly a thousand degrees, because the entire cave was extremely hot. Fortunately, it was inside a rock, otherwise it would be hard to predict a fire!

Li Xi'er saw the knife placed aside and touched it. It was extremely sharp, "Don't move!"

Suddenly, Commander He suddenly turned his head and scolded with a serious face.

"You can come in here, but you can't touch anything!"

"Otherwise, please get out!" He then said coldly.

"it is good!"

Feng Qingcheng comforted her in a low voice: "Commander He has a weird temper. You must not be on the same level as him!"

"Haha, who do you think I am? I'm not that stingy!"

Geniuses have weird personalities!

Li Xi'er chuckled and continued to watch Commander He's drawing process!
"I usually don't show this process to others, but, you guys..." He glanced at Li Xi'er and said calmly,
"Today is special!"

He was also making plans and was curious about everything Li Xier knew. If she was here, she might be able to give him good advice!
While he was talking, he poured all the tungsten ore powder and ink into the smelting furnace for high-temperature smelting!

Li Xi'er said "Hey" before she could stop her, and it was already too late!

"Commander He, what are you doing?"

Commander He looked innocent: "Just wait and see, you will get the thin tungsten wire soon!"

Seeing that they were a little tired after waiting for a while, he said to himself, "I smelted this tungsten ore last time. It requires extremely high temperatures to melt!"

Li Xier nodded. Tungsten ore powder is characterized by its high melting point, high strength, high conductivity and high corrosiveness.

It requires extremely high craftsmanship and drawing equipment.

Fortunately, Commander He has it.

When he poured the liquid into the mold, the drawing and cooling were really amazing. Unfortunately, the drawn wire was not uniform enough, the thickness was not up to standard, deformed and easy to break.

"This, this is the limit!" Commander He's face turned red, fearing that Li Xi'er would say something that was not up to standard.

Anyway, the tungsten powder has been used up, there is no chance for him to regret it!

"Have you used up the tungsten powder just now?"

Commander He was not afraid of being scalded by boiling water, so he said harshly: "This is already the best tungsten wire. Don't deliberately look for trouble! No one in this world can refine such good tungsten wire except me!"

He was right, because there was no one to refine this thing!

Seeing that Li Xi'er didn't speak for a long time, with a heavy look on his face, Commander He felt guilty for a moment and suddenly felt like a child who had made a mistake, "I've poured it all out!"

Li Xi'er was wondering what could make it more flexible?
This will definitely need a little lubricant!
She remembered what it was, a little bit, just a little bit before she could figure it out!
