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

After the calligraphy competition, many ministers left the study room in the Bunxuan 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 to leave when you retreat from the dynasty and dismiss the meeting, why did you follow your 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 instantly chuckled.

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

However, the secret agent flew back from the book, and as mentioned in the letter, he could not find any trace of Cheng Yingying.

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

But I didn't expect that today's Li Chengfeng personally asked this question.

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

"Father, my mother, was you captured by the Turkic dog thieves?"

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! Outside Youzhou City is the territory of the Turks, and if you lead your troops there, it will be tantamount to a sheep entering the mouth of a tiger, and I will not let you do this! Besides, you're too young to know how murderous the Turks were! Didn't I let you go to the place of the Turks, and sent you to die? ”

"But father, you have to believe that your son has the ability to do this!"

"No, don't say it! Tomorrow is your grandmother Queen Dou's birthday, remember to come over for dinner! Go back and have a good rest tonight, by the way, Feng'er, your performance today makes me very satisfied! Come on, in the future, the god king of the Tang Dynasty will be you! ”

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

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

Wu Gong behind him said fairly: "Eighth prince, it's getting late, why don't you go back early!" ”

"Okay, let's go back!"

……

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

So 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 doesn't even want to come out in the future, and plays at home every day.

At this time, Li Lizhen and Wu Xu, two little girls, came to the Zhenwang Mansion to meet 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're friends, just treat this place as your home in the future! You can come and play with me at any time! ”

"Okay, Wu Xu thanked the Eighth Prince!"

Wu Xu's face was slightly red. And Li Lizhi smiled slyly.

Li Lizhi came to Li Chengfeng and said, "Brother, I heard that you were in the study of Wenxuan Pavilion yesterday, but you were majestic, right?" ”

"What's wrong?"

"My father went back last night, and he kept chattering, it's terrible, Brother Feng'er is really amazing! Father also said that if you can find your teacher, it will be perfect! ”

"That's impossible, I can't even find my teacher, and my father doesn't even think about it!"

Li Chengfeng laughed.

His teacher is a man of the 21st century, if you want to find him in Datang, unless he is also like himself, he has crossed over!

"Brother Feng'er, is your teacher an immortal?"

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

"Haha, my father has actually been talking about it, what is that immortal who can teach Feng'er's younger brother so well!"

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

It can be described as a willow eyebrow and a half-moon eye, and Mo is on the moon eyebrow.

Li Chengfeng was stunned.

This Princess Changle was born a beauty embryo, could it be that Li Shimin and Queen Changsun both love her incomparably.

And Wu Xu on the side is also very smart.

But she was still young and had not yet grown.

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

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

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

Li Lizhen and Wu Xu followed curiously.

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

"Oh, I invented a solar charger!"

"Solar chargers? What's that? ”

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

Li Chengfeng directly scolded Li Liqing.

Li Lizhi couldn't help puffing out her cheeks and glanced at her younger brother.

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

"You can't learn it!"

"Hmph, brother, can't you teach me?"

"No, I can't teach it!"

Li Chengfeng was telling the truth, but Li Lizhi puffed out her cheeks and looked sullen.

"Eighth Prince, may I ask what you are going to do now to make this thing to collect electricity?"

Wu Xu suddenly asked the doubts in his heart.

Li Chengfeng's eyes lit up, 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 maker!" ”

"What? Cold air maker? ”

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

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

The two of them suddenly looked puzzled.

Cold air, can it still be made?

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

"Well, of course! As long as you have this idea and then devote yourself to 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 to absorb the sun's energy.

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

Li Lizhen and Wu Xu also followed.

When they came to the backyard of the Zhenwang Mansion, the two were instantly surprised.

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