Li Chengfeng was able to give such a perfect explanation, and Li Shimin was very pleased.

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

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

Li Shimin turned his head to look at the quirky Li Chengfeng and said with a smile: "Feng'er, you are always the first to leave the court for meetings. Why did you follow my father 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 suddenly 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.

However, the spy Fei Ge came back with a letter, and as stated in the letter, no trace of Cheng Yingying could be found.

Li Shimin originally did not plan to tell Li Chengfeng about this matter because he was afraid that Li Chengfeng would be too worried about it.

But unexpectedly, Li Chengfeng asked this question himself today.

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

"Father, was my mother captured by a Turkic dog thief?"

A sharp light flashed in Li Chengfeng's eyes.

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

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

"Nonsense! Just outside Youzhou City is the territory of the Turks. If you lead troops there, it is like a sheep entering a tiger's mouth. I will never let you do this! Besides, you are still young and don't know the Turks at all.

How cruel! If I ask you to go to the land of the Turks, isn't that the same as asking you to die?"

"But Father, you have to believe that my son is capable of this!"

"No, Feng'er, stop talking! Tomorrow is your grandma Queen Dou's birthday, remember to come over for the dinner! Go back and have a good rest tonight. By the way, Feng'er, I am very satisfied with your performance today! Work hard.

, from now on, the divine king of the Tang Dynasty will be you!"

After saying that, Li Shimin turned around and left, ignoring Li Chengfeng.

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

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

"Okay, let's go back then!"

…

After a night's rest, Li Chengfeng woke up early the next morning, and he woke up from the heat?

So Li Chengfeng thought for a while and decided 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 and will play at home every day.

At this time, two little girls, Li Lizhi and Wu Xu, came to the Prince's Mansion to pay homage to Li Chengfeng.

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

"Wu Xu meets the Eighth Prince!"

"Okay, okay, Xiao Wu, you're welcome. We are friends. From now on, just treat this place as your home! You can come and play with me at any time!"

"Okay, Wu Xu thanked the Eighth Prince!"

Wu Xu's face turned a little red, 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, right?"

"What's wrong?"

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

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

Li Chengfeng laughed.

His teacher is from the 21st century. If he wants to find him in the Tang Dynasty, he must travel through time like himself!

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

"No, how can there be any gods? They are all lies!"

"Haha, my father has been thinking about it, which god is it that can teach brother Feng'er to be so good!"

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

It can be said that the willow eyebrows have half-moon eyes, and the moon eyebrows are slightly on the road.

Li Chengfeng was stunned.

This Princess Changle was born a beauty. Could it be that both Li Shimin and Queen Changsun loved her immensely?

And Wu Xu on the side also looks very smart.

But she is still young and has not yet grown.

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

While Li Lizhi is the gentle type, Wu Xu is the heroic type.

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

Li Lizhi and Wu Xu followed curiously.

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

"Oh, I would have invented a solar charger!"

"Solar charger? What is that?"

"To put it simply, it's something that can convert the sun's heat into electricity! Even if you tell me, you won't understand!"

Li Chengfeng directly criticized Li Lizhi.

Li Lizhi couldn't help but puff up her cheeks and rolled her eyes at her brother.

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

"You can't learn!"

"Humph, brother, can't you teach me something?"

"No, you can't teach it!"

Li Chengfeng was telling the truth, but Li Lizhi puffed up her cheeks and looked unhappy.

"Eighth Prince, what are you going to do with this power-collecting thing now?"

Wu Xu suddenly asked the doubts in his heart.

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

"What? Cold air maker?"

"Ding, the surprise from Wu Xu, the naughty value is 10!"

"Ding, the doubt from Li Lizhi, the naughty value is 12!"

The two of them suddenly looked puzzled.

Can cold air still be produced?

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

"Well, of course! As long as you have this idea and then study it with concentration, there is nothing in this world that you can't create, it just takes a little time!"

"The Eighth Prince is so smart!"

Wu Xu looked at Li Chengfeng with admiring eyes.

Because since Li Chengfeng came to the palace, Wu Xu's knowledge seemed to have increased instantly.

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

Afterwards, Li Chengfeng took an ax and walked towards the backyard of the Zhenwang Mansion.

Li Lizhi and Wu Xu also followed suit.

When they arrived at the backyard of the Zhenwang Mansion, the two of them were instantly shocked.
