"Click, click!"

Li Chengfeng was very happy.

But thinking that he would soon have an electric fan to blow, Li Chengfeng was suddenly happy in his heart.

Gonggong Wu was guarding Li Chengfeng's side.

Gonggong Wu was puzzled: "Eighth prince, what are you doing here?" ”

"I'm cutting the boards!"

"This? Or let the slave help you sharpen? ”

"No, you can't sharpen, if you break my plank, it's a waste of time and wood!"

"Well, then! Then may I ask the eighth prince what can I do for you? ”

"You don't have to do anything, just fan me here!"

"Okay Eighth Prince!"

So, Gonggong Wu stood respectfully beside Li Chengfeng and watched Li Chengfeng sharpen the wooden board with a knife.

In the eyes of Wu Gonggong, Li Chengfeng's actions are purely just a child's playfulness.

The Eighth Prince must want to get a few pieces of wooden knives out to play, right?

However, Wu Gonggong didn't know that Li Chengfeng was actually making the leaves of the electric fan.

……

"Click, click......"

Li Chengfeng was slicing, and at the gate of the Zhenwang Mansion, an old man suddenly walked in.

I saw that the old man had a scruffy beard, his hands behind his back, and then staggered towards Li Chengfeng.

When Gonggong Wu saw this old man, his face immediately panicked.

Gonggong Wu immediately stepped out of the hall and stepped forward to greet the old man.

"Your Majesty, welcome to the Zhenwang Mansion!"

"Shh, Gonggong Wu, don't call me the emperor, in front of the eighth prince in the future, just call me old gentleman! At least I don't want to expose my identity as Li Yuan in front of my grandson at the moment, you know? ”

"This, okay, the emperor?"

"Huh? You repeat? Li Yuan's eyes shook.

"Yes, good old man!" Wu Gonggong Ma changed his words.

Li Yuan nodded with satisfaction.

With this kind of old gentleman's identity, he gets along very well with the Eighth Prince, and there is no sense of estrangement.

I don't want to be like other princes, as soon as I see myself, I just bow down and shout grandpa, so that Li Yuan can't get close to them or talk to them at all.

Because they are all restrained.

Only the Eighth Prince could speak loudly beside him, which made Li Yuan feel very comfortable.

This feeling of no estrangement is the real way for grandpa and grandson to get along!

"Click, click......"

Li Chengfeng continued to sharpen the planks.

Li Yuan looked at it, and then asked Gonggong Wu, "Gonggong Wu, what is the Eighth Prince doing?" ”

"He, he's sharpening the planks with a knife!"

"Oh? Cutting planks? Is it too boring to be idle? ”

So Li Yuan strode into the hall of the town palace and walked towards Li Chengfeng.

In fact, Gonggong Wu has long known that the Eighth Prince already knows the identity of this old gentleman, who is the Emperor Li Yuan.

However, Li Yuan didn't know it.

I thought that I was hiding my identity very well, and I could talk about my heart with the Eighth Prince.

At this moment, Li Yuan's thoughts are on the second layer, but Li Chengfeng's thoughts are already on the fifth layer.

"Yo, Eighth Prince, on this hot day, are you cutting the planks here? Is it so laid-back? ”

Li Yuan looked at Li Chengfeng with a smile.

Li Chengfeng raised his head, grinned, and said, "Grandpa, are you here?" ”

"Yes, I'm coming! It just so happened that the old man was free today, so he came to learn chess from the Eighth Prince! ”

Li Yuan touched his beard.

Gonggong Wu brought a stool and sat down for Li Yuan.

Li Yuan said: "Come on, Eighth Prince, you received 10,000 gold from the old man, then you have to travel your promise!" Come on, why don't you play chess now? It just so happens that the old man wants to learn the trick of hindsight today, you have to teach me! Hahaha......"

Li Yuan laughed openly.

However, Li Chengfeng frowned slightly, and said, "I'm sorry grandpa, I'm afraid I won't have time to teach you to play chess these days!" ”

"Oh? Why is that? You took me 10,000 gold, but you can't go back and say that you won't teach! ”

"No, I'll teach you how to play chess, but I'm not free right now, don't you see, I'm busy?"

"Click, click......"

So, Li Chengfeng continued to sharpen the planks again, without giving Li Yuan any face.

Li Chengfeng thought to himself, you deliberately pretended that I didn't know you, so since you don't call me grandson, I don't need to give you face!

Li Yuan smiled, but he didn't care!

Li Yuan looked at it, and there was a thin black line on the small wooden board.

The shape drawn by the black line resembles a curved blade.

Li Yuan frowned and said, "Eighth Prince, are you sharpening your knife?" If you want to play with a big knife, the old man will find you a few good knives, so why bother to make your own wooden knives? ”

"Oops, it's not sharpening knives! Am I cutting the blades of an electric fan? ”

"Electric fan blades? What's that? ”

"This, it's too much trouble to explain to you! Anyway, you don't understand! ”

Li Chengfeng shook his head, and turned to focus on sharpening the wooden board in his hand.

Li Yuan immediately became interested.

Electric fan leaves? Li Yuan had never heard of this new word.

So Li Yuan also looked curiously at Li Chengfeng cutting the wooden board on the side.

Li Yuan continued to ask: "Eighth Prince, what is the purpose of this so-called electric fan leaf?" ”

Li Chengfeng explained: "The electric fan blades use electricity to launch the rotational force, thereby driving the electric fan blades to rotate!" As soon as the leaf rotates, it can drive the air flow in the air, thus sending out a steady stream of cool breeze! That way, I don't have to be afraid of the heat! And as long as the power is continuous, my electric fan will not stop, so I can get through this hot summer coolly? ”

"What? This, electricity, electric fans, or a constant source of blowing? ”

After Li Chengfeng finished speaking, Li Yuan was suddenly confused by the second monk.

Every word Li Chengfeng said, Li Yuan understood what it meant.

But why did Li Yuan feel that this person was simply talking about the Book of Heaven when they were formed together?

Li Yuan couldn't understand a word, the only thing he understood was that what Li Chengfeng was doing now would be able to blow him from afar in the future!

But are these just two worn-out willow planks? Willow planks can also blow the wind?

Li Yuan couldn't help but be curious!

And Li Chengfeng continued: "But grandpa, if you want to make an electric fan that can blow the wind, the days are still long!" Let's not talk about whether an electric fan can be made, but just where to get the power is enough to give me a headache! But I still have a way, hehe! ”

Li Chengfeng smiled slyly, while Li Yuan pouted his beard and looked at the wooden board in Li Chengfeng's hand with an unaware expression.

He's still thinking, can this thing blow the wind out?

But it's been a long time.

So, Li Yuan's two deep eyes stared at the wooden board in Li Chengfeng's hand.

He watched like this, watching when Li Chengfeng was able to make that electric fan that could blow the wind!
