So, when Gonggong Wu began to shake the manual generator, the wooden electric fan actually began to spin?

The faster Gonggong Wu swayed, the higher the frequency of the electric fan blades rotated, so that a cool wind came out and blew towards the ministers on the side.

"Huh, what is this? Can you actually send out a cool wind out of thin air? ”

"Good fellow, how much does it cost to get this thing? On a hot summer day, if we had an electric fan, how cool it would be! ”

"That's it, this thing can not only relieve the heat, but also repel mosquitoes!"

"However, it is said that this thing called an electric fan was invented by the Eighth Prince himself, and there is no need to sell it in Chang'an City!"

"Alas, the Eighth Prince is a genius, what is it better than anything, there is no shame in Lai Guogong if he loses!"

The civil and military ministers of the Manchu Dynasty actually began to collectively stand on Li Chengfeng's side.

"This, this ......"

On the other hand, Du Ruhui was speechless in shock!

Li Chengfeng said: "Lai Guogong, please start answering!" Excuse me, what is the principle of electric fan rotation? ”

"Huh? This, this! ”

Du Ruhui frowned tightly, thought about it, and finally pointed at Wu Gonggong and said: "I know, the principle of the rotation of the electric fan is Wu Gonggong!" ”

"Poof...... Hahaha......"

Li Chengfeng held his stomach and laughed.

The Minister of Civil and Military Affairs outside the venue also couldn't help but laugh heartily.

Du Ruhui was full of black lines, and said: "Eighth prince, if it weren't for Gonggong Wu shaking the box somewhere, the electric fan would definitely not be rotating, could it be that the old man was wrong?" ”

"Yes, you're right! However, your answer is completely wrong, and it doesn't make sense! ”

"Huh? Then the eighth prince, tell me, what is the principle of the rotation of the electric fan? If you can solve it, the old man is willing to admit defeat! ”

Du Ruhui's face was full of helplessness, he glanced at Li Shimin innocently, as if to say: Your Majesty, this question, the old minister really can't answer it!

Li Chengfeng's stomach hurt when he smiled.

Then Li Chengfeng said: "The principle of making the electric fan turn is very simple! First of all, we need to prepare a generator and let him send out electricity to drive the rotation of the hub, and the hub will drive the blades of the electric fan to rotate, and it will emit a cool wind! Very simple question, next! ”

"Wait, wait, Eighth Prince! The generator and electricity you are talking about, Lao Chen has never heard of it? So you have to explain to the old minister, what is a generator? ”

Li Chengfeng pointed to the sky and said, "I haven't seen a generator, I've always seen rain and thunder, right?" The thing I invented was something that could make lightning out, and it didn't produce a lot of electricity, but it was enough to make an electric fan turn! ”

"What? Generating lightning? ”

"Ding, the shock from Du Ruhui, naughty value +10!"

"Ding, the shock from Li Shimin, naughty value +10!"

Li Chengfeng's words, the civil and military of the Manchu Dynasty were all surprised, but Li Yuan narrowed his eyes slightly.

Li Shimin's beard looked at Li Chengfeng with a little trembling, and said, "Feng'er, you say, can you make thunder and lightning?" How is this possible? ”

"Father, I invented electricity, not thunder!"

"Feng'er, don't deceive people! You're just a mortal, how could you invent such a thing as thunder and lightning, I don't believe it! ”

Li Shimin's old face was flat, thinking that Li Chengfeng was deceiving people.

But Li Chengfeng pulled out the plug of the electric fan hub, he smiled slyly, and said, "Or, father, you will try?" ”

"What?"

Li Shimin was suddenly empty.

This rabbit cub, is he going to use thunder and lightning to call himself?

However, these two small copper wires can't see anything peculiar, is it true that he really has electricity?

"Rabbit cub, are you electrocuting your father?"

Li Shimin's eyes widened, and he looked at Li Chengfeng angrily.

Li Chengfeng smiled happily: "How can there be, electricity can't kill people, so don't worry about my father!" ”

"Hmph, my father won't fall for you!"

"Okay, then my father doesn't dare to touch it, and I invite all the ministers in the audience to come and touch it to see if there is electricity! Excuse me, which minister has come up to test the electricity? ”

Li Shimin didn't dare to touch it, and Li Chengfeng turned his attention to the minister on the side.

Those ministers, you look at me, I look at you, their faces are full of fear, and no one dares to come up.

If there is really electricity, and the thing electrocuts someone, what can it do?

"Impossible, the old man doesn't believe that the Eighth Prince can use manpower to create thunder and lightning! Old man, I am willing to test electricity by myself! ”

In the end, it was Du Ruhui who stood up.

Because he wouldn't believe that the Eighth Prince could create thunder and lightning out of thin air!

If he really is, then it can only prove that the Eighth Prince was sent by the immortals.

So, Du Ruhui stepped forward and grabbed the two copper wires in Li Chengfeng's hand.

"Huh? It's okay? Haha, I'll just say, how could the Eighth Prince create thunder and lightning out of thin air? You see, aren't I all right? I didn't feel the blow of thunder and lightning at all! ”

Du Ruhui laughed happily.

However, Li Chengfeng looked sideways at Gonggong Wu and shouted: "Gonggong Wu, shake!" ”

"Yes, Eighth Prince!"

"Zizi Zi ......"

A touch of electricity was channelled along the copper wire into the center of Du Ruhui's hand.

"Yo, it's a little numb! But it's not thunder and lightning at all, is it? ”

Well? Something is wrong, why is it that the palms of my hands hurt a little and my whole body is starting to tremble?

"Ah......h

When the power came up, Du Ruhui suddenly let out a miserable scream, and then fell to the ground with a 'flutter', unconscious!

"Lai Guogong, Lai Guogong!"

Li Shimin was startled and hurriedly stepped forward to check on Du Ruhui's safety.

The Minister of Civil and Military Affairs of the Manchu Dynasty suddenly turned pale.

Li Shimin saw Du Ruhui fall to the ground and pull out, foaming at the mouth, his eyes were white, and his heart suddenly lit up.

It's over, Lai Guogong was actually electrocuted by the Eighth Prince?

"Rebel, rebel?"

Li Shimin turned to look at Li Chengfeng angrily and said, "Rebel Li Chengfeng, you actually dare to use electricity to kill Lai Guogong?" Are you guilty? ”

"What sin am I? Obviously, Lai Guogong doesn't believe in evil, and he himself came up and said that he wanted to test electricity! I didn't take the initiative to call him, how could I be blamed for that? ”

"How dare you quibble? Unfilial son? If it was me who was holding the copper wire just now, would you also be electrocuted? ”

"No, not to be electrocuted! But if you want to try, I'll call you! ”

"What? Rebel, rebel! What kind of sin did I, Li Shimin, create? Actually gave birth to such a rebellious son? Even I dare to murder? ”

"Phew, Li Shimin, don't pretend to me! When did I say I'm going to electrocute you? You didn't believe I could invent electricity, and you said you wanted to try it yourself! I thought, since you're going to try, I'll give you a try! As a result, Lai Guogong was stunned, and you called me a rebel? Okay, you Li Shimin, you shameless! ”

"What? What's your name? How dare you call me by my name? Rebel son......"

Li Shimin immediately became heartbroken.
