In the room, Li Chengqian, who was fiddling with a pile of wooden blocks, suddenly sneezed.

"Who is muttering bad things about me behind my back......"

Li Chengqian rubbed his nose and didn't pay much attention to it.

Carve wood with a knife on his own.

At this time, Qing Ci walked in from outside: "Your Highness, Miss Lu asks to see you." ”

"Let her in."

Li Chengqian, who was concentrating, casually agreed.

But suddenly he reacted that something was wrong: "Wait a minute, who are you talking about?" ”

He suddenly reacted so much, and it was a little inexplicable to make Qing porcelain.

Isn't there just a Miss Lu on board?

"It's Lu Wanjie...... Miss Lu. ”

"She wants to see me?"

"Are you sure?"

Li Chengqian's face was puzzled.

She shouldn't hate herself so much that the roots of her teeth itch, right, why did she suddenly come over to see her?

Could it be because she saved her, in order to repay the grace of saving her life, she has to make a promise with her body......

Oh my God.

I'm only eight years old.

I don't want to fall into the grave of marriage so early.

Seeing Li Chengqian's loveless look, Qing Ci was a little stunned.

After a long time, he asked, "Your Highness, should you let her in, or should you not let her?" ”

Li Chengqian waved his hand indiscriminately: "Let her in." ”

When Lu Wanjie came in, what she saw was Li Chengqian sitting at the table, holding a knife in one hand and a hammer in the other, fiddling with a pile of wooden strips and wooden blocks.

"Sister Wanjie is looking for me, but is there something wrong?"

Li Chengqian sharpened the wooden strips with a knife and asked without raising his head.

"Hmmm......"

"I'm here to ......"

"Thank you......"

Lu Wanjie's face turned red.

When I saw Li Chengqian this time, I didn't know what was going on, and there was a little rabbit jumping around in my heart.

Li Chengqian smiled slightly: "Didn't I say it, thank you and other things like that." ”

"If it's okay, Sister Wanjie will go and rest first, I don't have time to entertain you here, I'm embarrassed."

Lu Wanjie nodded, but her feet didn't move.

Li Chengqian was stunned for a moment, slowly raised his head, and saw Lu Wanjie peeking at him, and his face was as red as a ripe apple.

Such a scene really frightened Li Chengqian.

What the heck......

Lu Wanjie frightened Li Chengqian.

Li Chengqian suddenly raised his head and startled her.

Her face couldn't help but turn even redder, all the way to the base of her neck.

"I still have something to ask Your Highness......

Lu Wanjie's voice was as small as a mosquito.

Li Chengqian swallowed his saliva and put the knife on the table: "Sister Wanjie, please have something to say." ”

"I want to ask Your Highness ......"

"Was the fireworks really created by His Highness?"

Lu Wanjie looked up at Li Chengqian.

Li Chengqian was stunned for a moment, and then realized in his heart.

After shaking his head with a wry smile, Li Chengqian said, "It turns out that Sister Wanjie came to me because of the fireworks." ”

"Don't hide it from my sister, the fireworks were indeed made by me, and the fireworks scene by the Qujiang Pond was also made by me."

It turned out to be really him......

If Lu Wanjie was still skeptical of Li Tingxue's words before.

Now that she heard Li Chengqian admit it personally, she has completely believed it.

But Lu Wanjie's heart was still a little disappointed.

After all, in her heart, the person who created the fireworks was a man in white who was like a fairy descending to earth.

But now this man has slowly transformed into the image of Li Chengqian, an eight-year-old child, which is really a big impact.

Lu Wanjie bit her lip and said in a low voice: "Your Highness is really powerful, you can create such a beautiful thing......

"Hey, what's this, there's something more beautiful."

Li Chengqian waved his hand indiscriminately and said, "Okay, okay, I should be busy, if my sister is fine, she can really go." ”

This is the second time that Li Chengqian has issued an expulsion order.

He doesn't like it very much, and when he is doing things by himself, he is disturbed by others.

But Lu Wanjie still didn't move.

Without waiting for Li Chengqian to speak, Lu Wanjie suddenly asked, "What is Your Highness holding in your hand?" Isn't it, windmills? ”

"Windmills?"

Li Chengqian glanced at the half-finished product made of wood in his hand.

"Not to mention, it's a bit like a windmill."

Li Chengqian smiled and said, "But this thing is not a windmill, but a thing called a propeller." ”

"Propellers?"

Lu Wanjie looked at Li Chengqian puzzled.

Li Chengqian explained: "This thing is installed on the ship, if it is equipped, the kinetic energy of the ship will be greatly increased, and the dependence on manpower will be greatly reduced." ”

Hearing this explanation, as an ancient person, Lu Wanjie couldn't understand it at all.

Seeing that she was still puzzled, Li Chengqian simply assembled the semi-finished products together and ran to the window.

"Sister Wanjie, come quickly."

Li Chengqian beckoned to Lu Wanjie.

Lu Wanjie stepped closer.

Li Chengqian loaded the 'propeller' in his hand into a small wooden boat, and then put the boat into a wooden basin filled with water.

This so-called propeller has three structures: upper, middle and lower.

At the top is a huge windmill, in the middle is a rocker, and below is a small windmill.

Among the three structures, they are connected by notches cut out with a knife.

"It's coming!"

Li Chengqian shouted with some excitement.

Just when Lu Wanjie didn't understand why she was so happy, she suddenly felt a gust of wind blowing.

At this time, I saw that the big windmill was blown by the wind and began to spin.

When the big windmill rotates, the small windmill under the surface of the water also starts to spin.

And the boat also began to move forward slowly at the moment when the little windmill was spinning.

{Received Surprise +13......} from Lu Wanjie

"This ......"

"This mechanism is amazing, isn't it?"

Lu Wanjie was very surprised, and naturally there was a surprise value.

"Is this magical?"

Li Chengqian smiled slightly: "Now this is just a model, and when I return to Chang'an City, I will start implementing it immediately." ”

"When these things are loaded on the boat, not only can the wind be used to drive the thrust of the boat, but the propeller can also be used to speed up the propeller with a rocker."

"When the time comes, I will ask my father and the emperor to open a water trade route, and the merchant ships will cross the Yangtze River into the canal, so that the north and the south can communicate with each other."

"At that time, food prices in the north and south will be equal."

"I don't think there will be any starvation even if there are still people who can't afford to eat."

When Li Chengqian said these words, Lu Wanjie had been listening quietly beside her.

It was also the first time for her to feel that whether a person is talented or not does not depend on whether he can recite poetry and lyrics, or whether he will be sad.

It's about whether the person's talent is used in the right place.

If this person uses all his strength for the welfare of the country and the people, then this person is the most talented person in the world.

Don't talk about the side, just talk about the ten theories.

When Li Chengqian said the Ten Doctrines, she was there at the scene.

When she first heard it, she only felt that what Li Chengqian said was one-sided, and it was all nonsense.

But now that Datang has begun to apply the Ten Paths, the situation of more officials and fewer people has been broken in an instant.

The dismissal of officials who had been paid empty wages relieved most of the pressure on the people.

When thinking of this, Lu Wanjie also felt from the bottom of her heart that she didn't seem to hate Li Chengqian so much......
