"Queen Mother, what the sons said is true!"

Li Tai is very helpless now, but he doesn't know how to explain it.

"Yin'er, it's better for you to persuade him, this kid is crazy now!"

Li Erqi flicked his sleeve robe and said sharply.

"The real thing King Yue did is really inappropriate, the thunder and lightning of nature are too powerful, and they are not controlled by humans at all!"

Zhao Yin said with a smile.

In fact, Li Tai has this idea is good, but he just doesn't know enough about thunder and lightning!

"But isn't that the lightning rod you installed to control the lightning?"

Li Tai stalked his neck, still unconvinced.

The reason why he came up with the idea of controlling lightning was inspired by the lightning rod installed on the tower by Zhao Yin!

"That's not control at all, at most it's just a guide, leading the thunder and lightning into the earth......!"

Zhao Yin guessed that Li Tai would not be convinced by a few words, so he turned his head to look at Li Er, "Your Majesty can prepare a piece of silk and find a glass rod, and the son-in-law has his own way to explain everything!" ”

Before he set out for Goguryeo, he gave Lin Wu some drawings and ordered him to burn glass, the purpose of which was to install it on the windows and increase the light in the room.

However, due to the difficulty of glass manufacturing, the annual production was small and could only be used by the royal family.

"What do you want those things for?"

Li Er was a little puzzled, but he still waved his hand at Wang De behind him.

Wang Deluo bowed slightly, retreated, and after a while, he came back with two things.

Although silk and glass are both luxury goods, they are still very common in the palace!

"This colt is going to play a trick for you, everyone must keep their eyes open and see clearly, don't blink!"

Zhao Yin took the two things and smiled mysteriously.

When he said this, everyone immediately focused all their attention on his hands.

Zhao Yin put the two things together and rubbed them, and after a while, his hands were already flashing with electric light!

"But you see them all?"

Zhao Yin looked at everyone's bewildered faces and asked.

However, Li Er and Empress Eldest Sun all shook their heads.

"There seems to be a little lightning!"

On the contrary, it was Princess Changle who saw something.

"That's right, it's still my lady who is smart, and those are little lightning!"

Zhao Yin gave her a thumbs up.

"What? Those bright lights turned out to be lightning just now? ”

Hearing this, Li Tai's eyes suddenly lit up and he became interested.

"Yes, it's just that it's very small electricity!"

Zhao Yin nodded.

Triboelectric electricity, the physics knowledge that elementary school students have begun to learn in later generations, in this era, no one knows.

However, Zhao Yin's purpose is just to divert Li Tai's attention and make him stop playing with those thunderbolts, and it will be bad if he dies because of this!

"Not only that, but when the weather is dry in winter, there will be some static electricity on our clothes, but everyone doesn't pay attention to it!"

As soon as Zhao Yin's words came out, everyone immediately had an expression of sudden realization.

"So those are also electricity?"

Li Er has always believed that thunder and lightning are electricity, and he never thought that those small sparks were also electricity.

"Since the horse said that the thunder and lightning cannot be controlled by humans, is it possible to control these small electricity, so as to create electricity?"

Li Tai thinks very broadly, and from this small experiment, he thinks of making electricity.

"It's not impossible to make electricity, but you have to know how to do it!"

Zhao Yin nodded.

Sure enough, after his small experiment, plus a few words, Li Tai's attention was immediately diverted.

I saw him holding silk and glass rods with a smile on his face, constantly rubbing them.

And Empress Changsun looked at this scene and thought that he had recruited something unclean!

No way, there are few scientists who are not crazy!

"It's amazing!"

Li Tai looked at the electric light on the silk and said excitedly.

Seeing that his son finally stopped studying thunder and lightning, Li Er was relieved!

"Father, the son still has something to do, so he will retire first!"

Li Tai held two things like a treasure and gave Li Er a salute.

"Well, let's go back!"

Li Er nodded, wishing that he would go back quickly.

"Now you can finally rest assured!"

After Li Tai left, Empress Eldest Sun also breathed a long sigh of relief.

"Well, the fish in my garden have also picked up a life!"

When Li Tai was playing with thunder and lightning, he wanted to test how powerful it was, so he put the chain that led the lei into a small pond in the Imperial Garden, and as a result, no one of the koi fish was spared!

"Isn't it a waste of time to study these things all day?"

Empress Eldest Sun couldn't help but sigh.

"The queen mother is wrong, if electricity can really be made, it can be used for more than a steam engine!"

Although the steam engine ushered in the first industrial revolution, the second was electricity.

"Really?"

Li Er's eyes widened with an incredulous expression.

You must know that the role of the steam engine has refreshed his cognition, if electricity is more powerful than the steam engine, wouldn't it push Datang forward even more?

"That's natural, has the son-in-law ever deceived you?"

Zhao Yin smiled indifferently.

Of course, with Li Er's old-fashioned braincase, it is naturally unimaginable!

"Could it be that the steam engine was replaced by electricity?"

Although Li Er wanted to believe Zhao Yin, he still felt a little unbelievable.

"Nature is okay......!"

Zhao Yin planned to give him a few examples, "Take the train as an example, it can run about 100 miles per hour now, although it can be improved to 200 miles in the later stage, but if it is replaced by ......!" ”

"Wait, you just said that in the future, the train can be raised to two hundred miles per hour?"

However, before he could finish speaking, he was interrupted by Li Er.

If it is according to what Zhao Yin just said, it is twice as fast as it is now, and it only takes five hours to travel a thousand miles.

Li Er was so excited that he couldn't get any more, but he was blinded by Zhao Yin!

The way he looks now is no different from a dirt bun!

"If the steam engine is replaced with electricity, does Your Majesty know how many miles it can run in each hour?"

"Is it possible to reach four hundred miles?"

Li Er boldly guessed a number.

"Nope! It's 1,400 miles! ”

Zhao Yin said a conservative number.

In later generations, the speed of high-speed rail could reach 350 kilometers per hour, and the maximum speed could reach 600 kilometers per hour, but it was dangerous to a certain extent, and I was afraid that it would scare Li Er when I said it, so I chose this conservative number.

After converting to the timekeeping unit of Datang, it is 1,400 miles per hour.

"Then I will go to Mount Tai, won't it be an hour?"

At this conservative speed, Li Er was stunned.

Zhao Yin nodded calmly.

"Is electricity really so powerful?"

Li Er still can't believe it.

"It's still a conservative estimate!"

Zhao Yin nodded firmly.

But these are things that can only be achieved in many years, and telling Li Er now is just to let him understand the power of electricity!

"If Tyre can really make electricity, it will be a great achievement, haha......!"

Li Er laughed excitedly.
