"Comfortable?"

Some people are curious, but they have deep suspicions, the expression of the leader who is about to die just now does not look uncomfortable at all, how can it be very comfortable?

"Oh! Do you want to try? Very good, come on. ”

Li Zhao stopped this person, this person had no choice but to step forward and give it a try, the feeling of being a dead person, he couldn't forget it in his life.

Soon, Li Zhao asked everyone to try it again, not for anything else, just to let them know what 'electricity' is.

"This is electricity, electrical energy makes the body uncomfortable, it is what I said three days ago about conduction, electrical energy brings misfortune, but it gives great benefits"

Li Zhao briefly introduced electricity, so that everyone has a preliminary understanding, and in the future, everyone will have an in-depth understanding of electricity.

Of course, he didn't buy the system books from the store, but just recorded them based on what he had learned in his previous life, which was enough for the early stage, and the professionals he wanted to train were not how to generate electricity, but to maintain the electricity that had been generated, and the professional knowledge needed naturally did not need to be so comprehensive.

The students gradually became interested in what they heard, and they gradually learned what 'conduction' is, and they also knew that the human body is also a conductor, and they also knew that iron and bronze are conductors, and bronze is an ideal conductor.

Electricity can flow in a conductor like running water, from one corner to another, but they don't know what great benefits it can bring.

Shang Lu couldn't help but ask, "Sir, what are the benefits of electric energy?" ”

This issue is of concern to everyone.

Li Zhao looked at the appliances around him, and couldn't help but smile bitterly, his today's class is to let everyone know about electricity, and he didn't buy related electrical appliances, of course, buying electrical appliances is too expensive, just teaching, there is no need to waste money.

As for the benefits of electricity! Although it cannot be explained in real terms, it can be taught orally.

"The benefits are huge." Li Zhao picked up Shang Lu's topic, and ordered the slave standing outside the door, "Go, find a fan and an oil lamp." ”

When the students heard this, they didn't know what Li Zhao was going to do, but their interest was completely aroused.

Soon, the slaves brought fans and oil lamps.

There are many types of fans in this era, but most of the luxurious ones are popular among the powerful, and ordinary people can only use plant leaves to make them simple if they want to enjoy the coolness.

Wuming fan, three dukes and nine qing, Li Zhao is also vassal, and bought some and put them in the village.

The oil lamp is used for lighting in Daqin, and the oil here is not oil or kerosene, but vegetable oil.

Li Zhao picked up the Wuming fan and threw it to Shang Lu, "You fan me until you can't move." ”

Shang Lu picked up the Wuming fan and fanned it, the fan relied on manpower, and after a while, he felt exhausted, and in the end he couldn't fan anymore.

At this time, Li Zhao laughed and asked, "How long have you been fanning and you can't move?" ”

Shang Lu estimated and replied, "About a quarter of an hour." ”

"Can you still fan now?"

"The fan doesn't move!"

Li Zhao smiled and pointed to the Wuming fan and said: "This is the disadvantage of the human fan, if you change it to use the fan, it will be endless and inexhaustible." ”

This is an exaggeration, but it all shows the great advantages of electricity.

Endless?

When everyone heard this, they couldn't believe it for a while.

The fan is done by manpower, and when the power is poor, it is the time when the fan cannot be moved, where is it endless? It's a bit of a mouthful, but they don't dare to question the lord's words.

Li Zhao naturally knew that they couldn't accept it, but he wouldn't explain that when the electric fan appeared one day, I was afraid that these people would not be so respectful.

Then he took the oil lamp, lit it with a sickle, and placed it in front of them.

"As you can see, there are many steps to illuminate, and you need to have an oil lamp and a fire sickle by your side, and the only place that can illuminate is a corner."

Everyone nodded.

The range illuminated by an ordinary oil lamp is no more than one zhang, but for Daqin, this is already very advanced.

"But if you use electricity to illuminate it, it will be as bright as day."

What!

Everyone was shocked again, with different expressions, especially Shang Lu, whose ears moved slightly, as if he was very resistant to these words.

"Okay, this is electricity, it's more useful than that, and then I will tell you one by one, so that you can systematically understand electricity and understand the principle of electricity."

Soon, Li Zhao left the hall and left, leaving everyone to think deeply.

At this time, a person quietly came to Shang Lu's side and asked in a low voice, "Brother Lu, do you believe it?" How does it feel mysterious? ”

Shang Lu glanced at him, "It doesn't matter if I believe it or not, the important thing is that you can give an account to Your Majesty." ”

"It's a pity that the lord hasn't said what the electricity has to do with medical skills, I heard that His Majesty is most concerned about this, I have to wait to send this message to Grandpa Shang."

After a while, Shang Lu quietly walked to a corner, saw a waiter, he handed over the note in his hand, the waiter nodded to him, and hurried away.

"Your Majesty, I have heard and it has arrived."

In the palace, after receiving the report from the attendant, Shang Xinxing happily rushed to the main hall, and the sound could be heard from a distance.

Ying Zhengben was calm, but he couldn't help but be happy when he heard such a voice.

Yin Yan's injuries are like a day by day, especially in the past two days, the blood has become more and more ruddy, the skin is more tender, and it looks as vigorous as a young seedling, as if it is a different person.

Ying Zheng saw it in his eyes, and his mind became active.

Yin Yan has never had such a back-of-the-light change since she was born, but after Li Zhao's treatment, it seems to have been reborn, yes, in his eyes, this is a new life, just like getting immortality.

He concluded that this must be the effect of Li Zhao's medical skills, so he became more curious about Li Zhao's medical skills, especially when he learned that electricity was a very unfamiliar thing, so he looked forward to it even more.

He searched for the elixir but couldn't get it, thinking that it must be the wrong method, and at this moment, seeing the changes in his daughter's body, as if he saw hope, the fire of immortality was ignited again.

And this hope is likely to be electricity, plus blood exchange.

So, in the name of Li Zhaoyao's craftsman, he asked Shang Xin to pay close attention to him.

Today, Shang Xin came back to report, and he also heard that it must be a matter of Chang'an Township, how could he be unhappy?

"Quick, tell me what electricity is?"

When Shang Xin arrived at his side, Ying Zheng hurriedly asked.

"No! Promise! Shang Xin said repeatedly, then opened the note, looked at it carefully, and after a while, his face was different, as if he had eaten a cow at once.

Ying Zheng saw the change in his face, but he was still in a hurry, "Let's talk about it specifically!" ”

He could have seen it for himself, but he was too excited to reach out.

"Shang Lu said that electricity is a terrifying weapon of mass destruction, and it can make people die."

"What?" Ying Zheng's expectant heart was about to collapse in an instant.

Electricity is a big killer, so his immortality is gone?

For a while, like a defeated bull, lying on a high position in despair.

However, Shang Lu also said that although electricity can make people die, it can make fans fan forever without stopping.
