Tong Xuan couldn't care about the glass cover that he had worked so hard to get, and rushed forward with an arrow.

The power lab was filled with smoke and flames, and many people were fighting the fire.

The house is mostly made of wood, and it is difficult to extinguish the fire, which borrows the wind and is difficult to extinguish.

Kala–

However, the beams were burned off, a corner of the roof collapsed, and bricks and tiles fell to the ground.

Tong Xuan simply wanted to cry without tears, and he couldn't care about the fire at the moment, so he rushed in with his head in his hands.

"Hey, what are you doing?"

Someone immediately stopped him, but Tong Xuan was almost crazy, shouting, "Let go of me, let me in!" ”

"Are you crazy, such a fire, don't die?"

"Let go of me, I'm ......"

Tong Xuan was dragged to death, he couldn't break free no matter what, he was anxious and angry, he only felt that his blood was surging, his eyes were dark, and he fainted to the ground.

"Someone fainted, quick, quick!"

At this time, several members of the medical research team ran over and began to rescue.

"Bachelor Xia is here!"

I don't know who shouted, and everyone immediately got out of the way.

A young Hanlin walked over, squatted down, put his head on Tong Xuan's chest and listened for a moment, and said, "The heartbeat is normal, it should just be fainting." ”

This person's name is Xia Ying, and he is the head of the medical research team, the medical team and the power team are the closest.

"Get a basin of cold water!"

Xia Ying commanded, and immediately someone ran to the nearby water tank and came back with a basin of water.

Crash!

The way to rescue is simple and brutal.

A basin of cold water was poured on his head, and Tong Xuan suddenly sobered up.

He sat up, looked around blankly, and muttered, "Where is this, what happened?" ”

Immediately after, when he saw Xia Ying, he asked, "Master Xia, why are you here?" ”

Xia Ying thought for a while and said, "Brother Tong just fainted, the laboratory can be rebuilt if it is destroyed, if the body collapses......"

】

"Huh?"

Tong Xuan finally remembered that the laboratory was on fire, and the prince was still inside!

He rolled over and jumped up, pulled his leg and was about to rush in, when he was stopped again.

"Brother Tong, why are you doing this? The fire is so big that it's already hard to salvage......"

"Let go of me!"

Tong Xuan's heart was full of despair, as if he had seen his end......

"Master Tong, what's wrong with you?"

A childish voice sounded in his ears, and the people around him hardly paid much attention to it, but in Tong Xuan's ears, this voice was like a thunderbolt on a sunny day, and like a spring breeze.

He turned his head slowly, and then he saw the face that people loved and hated.

"Your Royal Highness the Crown Prince, you ...... You okay? ”

Zhu Jianshen shook his head and said, "I'm running fast, it's okay!" ”

At this time, the people around heard that the child was the crown prince, and hurriedly saluted.

Zhu Jianshen also returned the salute in style, Tong Xuan pulled Zhu Jianshen up as if he had been reborn, and said, "Your Highness, it is dangerous here, you better stay away." ”

"Master Tong, ...... those devices of yours?"

"Don't do it!"

"But...... You're not saying that those devices cost you a lot of effort......"

Tong Xuan waved his hand and said weakly: "Just go back and buy it again." ”

Zhu Jianshen nodded as if he didn't understand, and said, "Master Tong, that thing you made is so amazing, as long as you turn it, it can burst into flames." ”

"Huh?"

Tong Xuan stopped and said suspiciously, "Your Highness, what are you talking about...... Burst into flames? ”

"It's the shelf, and there's a ring of copper wire on it......"

Zhu Jianshen said while gesturing.

Tong Xuan's eyes suddenly became anxious: "Didn't I tell you, don't move!" ”

Zhu Jianshen pursed his lips and said, "I didn't move, I just, just ......"

"What's that?"

"Just turned around......"

"What did you turn?"

"That handle!"

Tong Xuan thought for a while and asked, "Is it the stick in the middle of the coil with a magnet on it?" ”

"Is it a magnet?"

Zhu Jianshen scratched his head and said, "I don't know what it is, but I can turn it when I see it, and then ......."

"And then?"

"And then it caught fire."

Tong Xuan had doubts in his eyes and asked, "Your Highness, tell me clearly, where is the fire?" ”

Zhu Jianshen replied cleanly: "Coil!" ”

"How can a coil catch fire?"

Tong Xuan shook his head, looking noncommittal.

Because the coil is copper, I haven't heard of it, copper can burn.

"It's a coil, and there's not a layer of cloth on it......"

Hearing Zhu Jianshen's explanation, Tong Xuan suddenly understood that it was the cotton yarn on the coil!

Although he didn't understand why the emperor asked him to wrap a layer of cotton yarn around the coil, he did so.

At the same time, another question came to his mind, why did the cotton yarn on the coil catch fire when he turned the magnet?

That's the question worth digging into!

According to historical records, humans first used heavenly fire, which was to thunder and crack trees, cause forest fires, and then bring the fire back to the cave.

Later, the Suiren clan invented drilling wood to make fire, and from then on, human beings no longer relied on God for fire.

Today, the way to make fire has become a fire sickle and a flint, both of which strike sparks and ignite the velvet, thus obtaining fire.

There is also a kind of fire fold, which is to burn mugwort, cotton and other materials until semi-permeable and extinguish the flame, when you need to use fire, you only need to open an opening, let the air circulate in, and it can be quickly rekindled.

It seems that it can be ignited with a single blow, but in fact, it is burned.

In any case, if you want to start a fire, you can't do without flint.

Tong Xuan's brain was running rapidly, because he thought of the group of old scholars of the Hanlin Academy at the beginning, in order to verify the absurdity of the Academy of Sciences, they did not hesitate to lead the sky to thunder, and in the end, five were killed and one was injured.

He noticed at the time that those who were electrocuted and injured were all scorched on the outside and tender on the inside.

In other words, to some extent, electricity, like fire, can burn people's bodies, and in severe cases, it can be fatal.

Moreover, the energy of electricity seems to be greater, and the whole process is completed in an instant.

The flame is a slow process, like a steam oven boiling water, which has to be heated little by little by adding coal, until finally the water can be boiled.

According to Zhu Jianshen's description, the cotton yarn wrapped around the copper wire suddenly caught fire, could it be that electricity appeared in the copper wire?

Does it mean that the experiment was successful?

His mood was mixed, both excited and hesitant.

Excitedly, electricity appeared in the copper wire, indicating that his research direction was correct.

At the same time, his heart was full of doubts, because he really couldn't figure out how all this electricity appeared.

In his understanding, nothing in the world can appear out of thin air.

It's like fire, which needs to be burned with firewood or coal, and when the fuel is exhausted, the fire disappears.

However, electricity seems to appear out of thin air, which makes people scratch their heads.
