And Li Yuan's stay is three days.

During these three days, Li Chengfeng was chipping wooden planks, cutting them from thick planks to thin blades of electric fans.

Three days later, the hard work paid off, and Li Chengfeng finally finished making the electric fan leaves.

Li Chengfeng drilled a small hole in the tail of the electric fan blades, and the nuts and screws made of wooden blocks locked their four leaves tightly.

In this way, the leaves of the electric fan are finally done!

Li Yuan looked at the cross electric fan blade in Li Chengfeng's hand.

His eyes suddenly lit up, and he said, "Eighth Prince, do you still know the wooden lock that the carpenter is proficient in?" You actually used wooden blocks to assemble those leaves made of wood steadily? ”

"I know a little bit, but I'm not proficient!"

Li Chengfeng replied. In his previous life, as a genius researcher, he was able to grasp the error of making things within millimeters.

Therefore, Li Chengfeng is sure that as long as the Zhenwang Mansion is electrified, then this wooden board electric fan can rotate without breaking.

"Okay, now that the leaves are done, the next thing to do is the generator!"

Li Chengfeng exchanged a handful of conductive copper wires from the system, and then used the principle of using frictional electricity to make a hand-shaken power generation box.

Another three days passed.

Li Chengfeng finally finished the manual power generation box.

Electric fan blades, energized rotating hubs, conductive copper wires, plus a hand-shaken power box.

It took Li Chengfeng six days to finally finish making a complete, working electric fan.

And Li Yuan, also early in the morning, came to the town king's mansion to admire Li Chengfeng's masterpiece.

Li Yuan found that this grandson of his was not only smart and witty, but also loved to invent, and he was really a genius among geniuses!

But Li Yuan found a serious problem.

That is, although Li Chengfeng is smart, he doesn't like to learn.

didn't go to class in Wenxuan Pavilion, but he also cleaned up Cheng Yanjin, who asked him to go to class, and asked Cheng Yanjin to take the initiative to go to the execution table and receive 100 rods?

The so-called people must not learn, and there is no end to learning in a person's life.

If Li Chengfeng doesn't study, once the ink in his stomach runs out, then he will have no room to grow!

Li Yuan seems to be aware of this problem as well!

……

As soon as Li Yuan entered the hall of the Zhenwang Mansion, he found that Li Chengfeng was assembling an electric fan, and Li Yuan was immediately interested.

"Yo, grandpa you're here so early?"

Li Chengfeng turned his head and greeted Li Yuan like Li Yuan.

Li Yuan nodded with a smile and said, "Yes, Eighth Prince, the old man came to see how your invention went?" If we make an electric fan, then we can make the next issue, right? ”

"Well, that's nature! When the fan is ready, we can play chess while blowing the wind! Isn't it beautiful? ”

"Haha, you little clever ghost?"

Li Yuan touched his beard and smiled, and asked tentatively: "Eighth Prince, the emperor asked you to go to Lai Guogong's Wenxuan Pavilion to study, why don't you go?" ”

"Hmm...... Because, Du Ruhui can't teach me! But most of all, I don't want to play with a bunch of teenage kids! Playing with them is a waste of time, energy, and boredom! ”

Saying this, Li Yuan suddenly frowned tightly.

Li Yuan said: "Eighth prince, the so-called people must not learn!" How can you be so arrogant? If you don't study, you'll never grow! ”

"That's wrong, because Lai Guogong really can't teach me! I will do what he will, I will not if he can't, I will too! ”

Li Chengfeng replied casually, which really made Li Yuan angry.

This little rabbit cub, is his heart really higher than the sky?

Even Du Ruhui, who was the prime minister of the dynasty and one of the twenty-four heroes of the founding of Lingyan Pavilion, looked down on him?

Du Ruhui's talent is one of the best in the Tang Dynasty.

Even Li Yuan respected Du Ruhui for three points, but he didn't want to, but he was despised by the Eighth Prince?

Li Yuan immediately couldn't sit still.

So Li Yuan touched his beard and laughed.

"Hahaha...... Young and ignorant, you are really too young! The Eighth Prince! ”

Li Chengfeng turned his head and looked at Li Yuan for some reason.

The old man laughed strangely, and startled himself.

"What are you laughing at? Geezer? ”

"Huh? You dare to call me an old man? Do you know who I am, who the hell is? ”

In Li Yuan's eyes, a trace of profound light suddenly appeared.

Li Yuan said: "I have a showdown, I won't pretend, in fact, I am your grandfather, the father of Li Shimin, the emperor of the Tang Dynasty, and the emperor of the Tang Dynasty, Li Yuan!" ”

Li Yuan had a showdown, and he touched his beard and laughed.

He thought that he would have a showdown with his identity, and Li Chengfeng would definitely be shocked when he heard it.

However, Li Chengfeng just chuckled and said, "Oh, then I also have a showdown, and I won't pretend." Actually, I already knew, you are my grandfather Li Yuan! ”

"What? You already knew? Who told you that? ”

Li Yuan said, and glared angrily at Gonggong Wu on the side, as if asking, did you tell the Eighth Prince my identity?

Gonggong Wu's face was full of panic.

And Li Chengfeng said: "Grandpa, don't scare Gonggong Wu, in fact, I have already guessed that you are the emperor!" ”

"And how do you know?" Li Yuan asked.

Li Chengfeng replied: "I see you, you travel leisurely every day, you don't need to go to the court, but you do live in the palace!" Moreover, you can enter and leave my Zhenwang Mansion at will, and the guards will not dare to stop you! This can show that your identity is in the palace, and you are a first-class high-ranking official and minister! But you don't have to go to the court, but you have more power than the twenty-four princes of Lingyan Pavilion! Dare to ask the entire palace, in addition to the Emperor Taishang, who still has such power? Right? Grandfather! ”

Li Yuan was stunned for a moment, then laughed and said, "Haha, the old man's grandson, he is really smart, when I see it today, it really deserves its reputation!" ”

Li Yuan was very pleased that Datang could produce such a smart prince.

And Li Chengfeng is only six years old now, if he grows up, what will he do?

The future is promising, the future is promising!

In fact, last night, Li Shimin found Li Yuan.

Li Shimin saw that Li Yuan had been running to the Zhenwang Mansion these days, and Li Shimin wanted to borrow Li Yuan's hand and ask him to persuade the Eighth Prince to go to Wenxuan Pavilion to study.

Li Yuan immediately agreed.

And Li Yuan still has a little pride in his heart.

Because Li Yuan thinks that you, Li Shimin, Tang and Tang Emperors, have no way to take the prince? Don't you have to see me Li Yuan come out?

So Li Yuan came to the Zhenwang Mansion early this morning, hoping to persuade Li Chengfeng to study in the Wenxuan Pavilion.

But at this moment, he couldn't help but have a headache when he looked at the proud Li Chengfeng, it seemed that this matter was much more difficult than he imagined!

Because Li Chengfeng didn't want to go to school at all.
