Li Shimin was very pleased that Li Chengfeng could give such a perfect explanation.

After the calligraphy competition, many ministers left the study room in Wenxuan Pavilion.

However, Li Chengfeng secretly came to Li Shimin's side and walked with Li Shimin.

Li Shimin looked sideways at the eccentric Li Chengfeng, and said with a smile: "Feng'er, you are usually the first one to go when you leave the court and leave the meeting. Why did you follow up with the emperor today?"

"Father, I want to know, have you found the whereabouts of my mother Cheng Yingying?"

"what?"

After Li Chengfeng finished speaking, Li Shimin's heart skipped a beat.

That's right, although he sent a team of Xuanjia troops to Luojiang Village in Youzhou City to find Cheng Yingying's whereabouts.

But the secret agent Fei Ge sent a letter back, and as stated in the letter, he could not find any trace of Cheng Yingying.

Li Shimin originally didn't intend to tell Li Chengfeng about this matter, because he was afraid that Li Chengfeng would be too worried about it.

But unexpectedly, today's Li Chengfeng asked this question himself.

Li Shimin pondered for a while, and said: "Feng'er, to be honest, I haven't found your mother's whereabouts yet, but you don't have to worry, Father and I will definitely give you a satisfactory explanation!"

"Father, my mother, have you been taken away by Turkic thieves?"

A sharp light flashed in Li Chengfeng's eyes.

Li Shimin sighed, shook his head and said, "I'm not sure, but I can't deny it!"

"Father, I want to personally lead the troops to Youzhou City to find my mother!"

"Nonsense! Outside Youzhou City is the territory of the Turkic people. If you lead troops there, it is like a sheep entering the mouth of a tiger. It is impossible for me to let you do this! In addition, you are still young, and you don't know the Turkic people at all. How cruel! If I let you go to the place where the Turks lived, wouldn't that be the same as sending you to your death?

"But father, you have to believe that my son has this ability!"

"No, Feng'er, don't talk about it! Tomorrow is your grandma's birthday, Empress Dou, remember to come to the dinner party! Go back tonight and have a good rest. By the way, Feng'er, I am very satisfied with your performance today! Work hard , from now on, you will be the **** king of the Tang Dynasty!"

After finishing speaking, Li Shimin turned around and left, ignoring Li Chengfeng.

Li Chengfeng sighed, then turned around and wandered aimlessly in the Wenxuan loft.

Eunuch Wu behind him said: "Eighth Prince, it's getting late, why don't we go back early!"

"Well, let's go back then!"

After resting all night, Li Chengfeng woke up early the next morning, but he was woken up by the heat?

After thinking for a while, Li Chengfeng planned to make a cold air generator.

That thing is actually the 'air conditioner' of the 21st century!

After all, how can electric fans be as popular as air conditioners?

As long as there is an air conditioner, Li Chengfeng will not even want to come out in the future, just stay at home and play every day.

At this moment, two little girls, Li Lizhi and Wu Xu, came to visit Li Chengfeng at Prince Zhen's Mansion.

"Brother Feng'er, I'm here to play with you!"

"Wu Xu pays homage to the Eighth Prince!"

"Okay, Xiao Wu, you are welcome, we are friends, you can treat this place as your home in the future! You can come to me to play anytime!"

"Okay, Wu Xu thanked the Eighth Prince!"

Wu Xu's face turned reddish. And Li Lizhi smiled slyly.

Li Lizhi came to Li Chengfeng, and said: "Brother, I heard that you were very impressive in the study of Wenxuan Pavilion yesterday, didn't you?"

"What's wrong?"

"Father went back last night and kept talking about it, it's amazing, brother Feng'er is really amazing! Father also said, if you can find your teacher, it will be perfect!"

"That's impossible, I can't even find my teacher, let alone Father!"

Li Chengfeng laughed.

His teacher is a man of the 21st century. If he wants to find him in Datang, he must have traveled through time like himself!

"Brother Feng'er, is your teacher a god?"

"No, how can there be any gods? It's all a lie!"

"Haha, my father has been talking about it all the time, after all, it is that **** who can teach Brother Feng'er so well!"

Li Lizhi covered her mouth and laughed lightly, her two big eyes narrowed into crescent moons.

It can be said that Liumei has half-moon eyes, and Moshang's moon eyebrows are slightly.

Li Chengfeng was dumbfounded.

This Princess Changle was born a beauty, could it be that Li Shimin and Empress Changsun both loved her extremely.

And Wu Xu at the side is also very agile.

But she is still young and has not yet grown up.

But judging from her appearance, Wu Xu in the future will definitely be a beauty embryo no less than Li Lizhi.

And Li Lizhi is the gentle type, and Wu Xu is the heroic type.

Li Chengfeng felt a little bored, so he walked into the hall, picked up a solar panel, and fiddled with a string of copper wires.

Li Lizhi and Wu Xu followed curiously.

Li Li asked, "Brother, what are you doing?"

"Oh, I invented a solar charger!"

"Solar charger? What's that?"

"To put it simply, it is something that can convert the sun's heat into electricity! You don't understand it!"

Li Chengfeng directly rebuked Li Lizhi.

Li Lizhi couldn't help puffing up her cheeks, and gave her younger brother a white look.

"Hmph, if you don't understand, you don't understand, but I can learn!"

"You can't learn it!"

"Hmph~www.mtlnovel.com~ Brother, can't you teach me?"

"No, I can't even teach it!"

Li Chengfeng was telling the truth, but Li Lizhi puffed up her cheeks and became sullen.

"Eighth Prince, may I ask what you are going to do with this electricity-collecting thing?"

Wu Xu suddenly asked the doubt in his heart.

Li Chengfeng's eyes lit up, he snapped his fingers, and said, "Smart, this solar panel is just an auxiliary item. In fact, what I really want to do is this cold air generator!"

"What? A cold air generator?"

"Ding, surprise from Wu Xu, naughty value +10!"

"Ding, doubts from Li Lizhi, naughty value +12!"

The two suddenly became puzzled.

Can cold air be produced?

"Brother Feng'er, can this, cold air, also be produced?"

"Well, of course! As long as you have this idea and then devote yourself to studying it, then there is nothing in this world that you can't make, it just takes a little time!"

"The Eighth Prince is so smart!"

Wu Xu looked at Li Chengfeng with adoring eyes.

Because since Li Chengfeng came to the palace, Wu Xu's knowledge seems to have increased in an instant.

Immediately afterwards, Li Chengfeng installed the solar panels and copper wires, and put them outside the door to dry in the sun to absorb the sun's energy.

Afterwards, Li Chengfeng took an ax and walked towards the backyard of Prince Zhen's Mansion.

Li Lizhi and Wu Xu followed suit.

When they came to the backyard of Prince Zhen's Mansion, the two were instantly taken aback.

I saw that the backyard of the Zhenwang Mansion, which was originally a wasteland, has now become a vibrant green grassland.
