Li Chengfeng also nodded slightly, showing respect.

In terms of force, Qin Qiong is also a famous general in today's Tang Dynasty.

In the entire palace, except for the military god Li Jing, who can suppress Qin Qiong, the rest of the generals have to be honored as seniors when they see Qin Qiong.

If Li Chengfeng really wants to learn martial arts, maybe he can really go to Qin Qiong!

"Eighth prince, the old minister won't disturb your meal! The old minister retires! ”

"Well, okay, let's go, don't come to quarrel with me to go to Wenxuan Pavilion to study in the future! You know? ”

Qin Qiong pursed her lips, pondered for a while, and finally nodded slightly, "Yes, Eighth Prince!" ”

So, Qin Qiong, Wei Zheng and Wei Chi Jingde turned around and left the Zhenwang Mansion.

The four of them couldn't fight Li Chengfeng, so naturally they returned in vain.

And after Li Shimin knew about this, he also had a headache.

People must not learn, if Li Chengfeng does not go to Wenxuan Pavilion to study, wouldn't it be a waste of his innate intelligence?

After thinking about it carefully, Li Shimin decided to release Li Chengfeng for a few days before speaking.

Wait until you finish dealing with the important matters in the court, and then teach Li Chengfeng well.

He didn't believe that he Tang and Tang Emperors would not be able to fight an eighth prince?

……

On the other hand, Li Chengfeng, in the past few days, Li Chengfeng does not have to go to the court or go to class, and he is also idle and bored in the Zhenwang Mansion.

Li Chengfeng stood at the gate of the Zhenwang Mansion and looked up at the sky.

The scorching sun shone on the earth, setting off a hot dusty wind.

"It's so hot! The temperature is at least 38 degrees or more, right? ”

Li Chengfeng wiped the sweat from his forehead.

Besides, it's only June, so it's so hot?

If you wait until the time of July and August in the future, then you can't burn people to death?

Li Chengfeng was a little hot and couldn't stand it.

In the Zhenwang Mansion, Gonggong Wu ran from the bedroom to Li Chengfeng is back.

Wu Gong said fairly: "Eighth prince, it's hot outside, you go into the house to cool off, and the slave will fan you!" ”

"Fan Fei? I think it's better to forget it! It's so hot, you're fanning all the hot air! The hotter it gets, the more comfortable it is for me to lie quietly on the mat! ”

"This, but the eighth prince, you can't stand outside in the sun, if you suffer from heat stroke, the slave can't afford the consequences!"

"It's okay, this prince is in good health, he won't suffer from heat stroke!"

"Well, then!"

Gonggong Wu was helpless, so he had to stay by Li Chengfeng's side and never leave.

In the Tang Palace, every time the heat is scorching, Li Shimin and the important ministers of the court will also use ice cubes to cool off.

But that's not a long-term solution.

The hotter the weather, the faster the ice melts.

After the cold air emitted by the ice cubes, it was even hotter and hotter.

Not to mention that Li Chengfeng can't stand it, even if Li Shimin is dealing with the government every time, he will retreat from the court because of hot upset.

"No, it's getting hotter and hotter, where can I afford it? I've got to get an electric fan! ”

Li Chengfeng frowned at his little brow, and he was paying attention to something in his heart.

Li Chengfeng thought to himself, in an environment like Datang where there is no electricity, it is definitely impossible to turn on the air conditioner.

But making a simple electric fan by yourself should be no problem, right?

Li Chengfeng originally wanted to exchange an air conditioner from the system.

But there is no such thing as an air conditioner in the system.

I think so, if anything can be redeemed.

Li Chengfeng simply exchanged a pistol and came out.

In the future, if you have a pistol to defend yourself, who dares to plot against yourself, you will be shot when you go up, and see who dares to be presumptuous to yourself?

But the system also seems to know that if you can exchange naughty points for those items, it will definitely upset the balance.

So even if Li Chengfeng has enough naughty value, he can't buy those power technology inventions in the 21st century.

However, Li Chengfeng himself did not panic at all.

Because he has not forgotten that he was a scientific genius during his lifetime.

As long as he has enough materials, let alone an electric fan, even if it is an air conditioner or an aircraft cannon, Li Chengfeng can make it himself.

Now that the weather is getting hotter and hotter, Li Chengfeng feels that he should also make some preparations for the arrival of the scorching heat.

It's a bit unrealistic to make an air conditioner, but making a simple electric fan is still not a problem for Li Chengfeng!

……

"Grandpa Wu, go, find me two planks!"

"Okay, Eighth Prince, but what do you want the planks for?"

"Stop talking nonsense, just find me! Remember, look for a good wood plank, otherwise it will break easily! ”

"Okay Eighth Prince, wait a minute!"

After that, Gonggong Wu ran to the backyard to find the plank.

And Li Chengfeng staggered and returned to the hall of the Zhenwang Mansion.

This town palace is indeed very large, but because only Li Chengfeng is currently living alone, in addition to Gonggong Wu and the two maids, there is only one patrolling guard left!

Therefore, the entire Zhenwang Mansion is still a little empty.

Soon, Gonggong Wu found two wooden planks that were thick on the right and back.

Wu Gong said fairly: "Eighth Prince, these two planks are made of the branches of green willow trees, the material is very good, and they are also very tough!" ”

"Well, okay, show it to me!"

Li Chengfeng took the green willow plank and waved it lightly in his hand a few times.

Although the material of these two wooden boards is good, it is still not as good as the plastic electric fan blades.

"Shhh...... Why don't you go to the blacksmith shop and get two iron fan leaves? ”

"No, the iron blades are too heavy, and according to the current iron shop process of Datang, they will definitely not be able to achieve the effect of the electric fan blades I want!"

"Forget it, I'll use these two planks as electric fan blades first! At least you have to make an electric fan first, otherwise it will really heat people to death in the summer! ”

Li Chengfeng wiped the sweat from his forehead, and then took two willow planks and came to the gate of the hall.

Li Chengfeng found a well-lit, shady place and sat on the ground.

"Grandpa Wu, find me a sharp knife, it must be sharp!"

"Okay, Eighth Prince, I'll find it for you!"

Gonggong Wu can be described as obedient to Li Chengfeng.

Because Li Chengfeng is his master, no matter what Li Chengfeng wants, as long as Gonggong Wu does what he tells him, he will be fine!

Although Gonggong Wu is now in the palace, he is just a small eunuch.

But Gonggong Wu believes that as long as he serves the Eighth Prince well, he will definitely be able to rise to prominence in the future, and maybe he will be able to become the chief eunuch.

That's a lot more face!

Immediately afterwards, Gonggong Wu found a sharp knife and handed it to Li Chengfeng.

Li Chengfeng spent 10 naughty points from the system and exchanged it for a watercolor pen!

Subsequently, Li Chengfeng divided the willow tree board into four parts, and first drew the traces of four electric fan blades on the small wooden board with a watercolor pen.

I sharpened it with a knife again!
