Dare to love her second brother is going to the market to buy children's gadgets, this is really a big embarrassment!

"I don't want that kind of windmill, it's the kind of windmill that can fit in the river, so big!" As he spoke, he gestured with his hand and drew a big circle in the air: "This windmill can get water up from the river!" ”

At this moment, everyone looked at Ouyang Ningxin with doubts, and was extremely curious about the windmill in her mouth.

"Isn't there here?" Ouyang Ningxin looked at everyone's reactions and asked without giving up.

The crowd shook their heads.

Ouyang Ningxin looked at everyone's reactions, a little lost.

Suddenly, he said, "How about going and see the nearest river here?" ”

So they came to the river five miles away from the village, and this river was already the closest river to the village.

"This is it."

Xie Haicheng showed the way and led a few people to the riverbank.

The river is more than ten meters wide, but the water is not very fast, because the surrounding area is relatively flat, so there are no rapids.

"The name of this river is the Mandarin Duck River, and the water is very clear and sweet, and its source flows from the rock crevices of the innermost mountain."

Xie Haicheng seemed to know every village in the small village of the city, and he could know the source of a river so clearly.

It's just that the river is relatively deep, and it is more dangerous for ordinary people to come here to get water, so few people come to this river to get water, and now they drink water from wells, and their crops can only rely on the rain to store water.

For drought-tolerant crops, it is enough to rely on the water stored when it rains all day long, but it is not possible to grow rice.

Ouyang Ning looked at the river and found that the place near the bank was not very deep, and an adult would stand down just to the place where his neck came out, this height was just right, if a windmill was placed in this position, it would be very suitable.

"It's good here."

Ouyang Ningxin nodded at the clear river water, obviously satisfied with the depth of the river water at this location.

"Let's go, go back and draw something for you!"

When Ouyang Ningxin saw that it was almost there, he planned to go back and draw the drawings of the windmill, so that he could let people build it as soon as possible.

"By the way, Mo, can you lend me the craftsman in your hand?" Ouyang Ningxin, who had just taken a step, suddenly stopped, turned around and asked the man who had been closest to her.

"You can use it if you want to, aren't my people also your people!" Yu Lingmo generously betrayed his subordinates unconditionally, and he was very happy to betray them.

Because of the name she called him, since what happened last night, her attitude towards him has changed, she has become a little gentler, and she will care more about him, and the name of him has changed from the previous Yu Lingmo to Mo.

This ink word, she is the only one who shouts, and in the future, it will belong to her alone!

"Really? Then you're welcome! Ouyang Ning was excited, stepped forward and hugged the man's arm, and hugged him in his arms: "It turns out that the legendary King Ling, who only has a cold face, is actually such a good talker!" ”

Ouyang Ningxin teased.

Someone is a little reluctant to say this: "Could it be that this king has a cold face to the princess?" Well? ”

Ouyang Ningxin shrunk her ears, and the man's deep and mellow voice sounded low in her ears, crispy, making her a little unbearable.

After thinking about the man's words carefully, it seems that there really isn't, and when they first met, they were defensive about her, but they didn't have a cold face.

But Ouyang Ningxin was a little unconvinced: "The prince is cold-faced to everyone else!" ”

Now someone blackened his face: "Does the princess want this king to talk to others with a smiling face, especially, women~"

The man stared at the woman's lips as if he were going to swallow the little woman alive if she said yes.

"You dare!" The little woman was about to go crazy: "Yu Lingmo, if you dare to stare at other women with smiling faces, see how I will clean you up!" Ouyang Ning waved his fist low and said threateningly.

The man rubbed the woman's hair and said dotingly: "Don't dare, so this king can only face others coldly." ”

"Hey, can you two be careful? This, this we are still there, are you when we don't exist? Ouyang Yu covered his eyes, he really couldn't stand it.

Do these two really think that they don't exist, why are they embroidering at any time?

Ouyang Hao said that his heart was very bitter, which made him feel a little flurry.

It turned out that when the two of them were biting each other's ears and talking just now, they were looking at me from the perspective of others, so Ouyang Hao couldn't help but remind him.

"Ahem!"

Ouyang Ningxin stopped and realized how ambiguous the movements of the two of them were at this time, and quickly took a step back.

glanced at his second brother in a blink of an eye, and motioned for him to resolve the embarrassment in front of him.

But this time, Ouyang Hao pretended not to receive his sister's eyes, just "cough!" He coughed.

In the end, Ouyang Ningxin could only let go of the hand holding someone's arm in the strange eyes of several people, and then calmly walked in front first.

Several people returned to Xie Mansion in a majestic manner, and the speed was faster than before, because Ouyang Ning was thinking about things in his heart, so he was a little faster than before.

The others were very curious about what she wanted to draw, and several people could almost guess that what she wanted to draw was probably the windmill she had just mentioned.

Ouyang Ningxin returned to Xie Mansion and turned his head to look at Xie Haicheng: "Borrow your study!" ”

Before Xie Haicheng could answer, Ouyang Ningxin had already taken the lead in selling and walked towards Xie Haicheng's study.

And before Xie Haicheng could nod his head in agreement, he had already been thrown out for a long distance, so he hurriedly followed again.

Several people turned around several times, and they all crowded into the not very spacious study on Xie Haicheng's mansion.

And the owner of this study was squeezed behind several people.

Yu Lingmo has always been in the position closest to Ouyang Ningxin, followed by Ouyang Yu and Ouyang Hao, don't look at the two of them, their curiosity is heavier than anyone else.

Ouyang Ningxin came to the study, found paper and pen, and brushed the ground to construct a picture on it, because she didn't know how to use a brush, whatever she wanted, she usually carried her own special charcoal, at this time she used a thin charcoal pen to outline a model of a windmill on it.

In fact, she is not very familiar with the windmill, she only remembers the shape of the windmill, and the working principle, she can draw the picture, and she can also tell its principle, but she asks her to build it herself, but she can't build it, because she is not a craftsman.

It didn't take long for a picture of a windmill to come out.

Ouyang Ningxin's painting is okay, although it is not professional, but the place where it should be painted is also very detailed, and it looks clear.

Ouyang Ningxin painted the windmill she saw when she was a child living in her hometown, and she was very curious about the windmill in the village at that time, and ran to see it every day.

Later, when I grew up, I also had some research on the principle of this windmill.

A few people looked at the complex and detailed pictures that gradually emerged on the picture, and then saw Ouyang Ningxin pick up the drawing and gently shake the carbon ash on it.

"Let's take a look, the picture above is the windmill I just talked about, of course, it's not what you imagine a child's thing, it's very useful!"

"First of all, we have to put this thing in water, but we can't soak it all in the water, as long as a third of it is in the water."

Ouyang Ningxin pointed to a place on the picture and said: "Here, it will rotate because of the wind blowing, and then this axis rotates, and the multiple small bamboo tubes immersed in the water below have been filled with water, with the help of the wind to make the shaft wheel rotate, drive the water in the bamboo tube, and then drink the water that is brought up and flowed out to the ground, so that we can easily lead the water in the river to the ground without spending more manpower and material resources." ”

Ouyang Ningxin only cared about explaining, not noticing the completely stunned expressions of everyone, and then continued to explain: "Of course, this can only be done with the help of the power of the wind, when there is no wind coming, and water is urgently needed, at this time, we can use manpower instead, and a few people can drive this axis together." ”

After Ouyang Ningxin finished speaking, he looked up at a few people, only to find that they didn't know when they all looked at the drawings with wide eyes, as if they saw something strange in this world.

Even King Ling, who usually had a calm face when he saw any rare treasure, was completely shocked at this time.

Ouyang Ningxin was also shocked by their reaction, especially Xie Haicheng's reaction, he still had his chin open and forgot to close it.

In the end, it was Yu Lingmo who reacted in advance, reached out to take the drawings, and said to Ouyang Ningxin: "Xin'er, do you know that you are now a great hero of the Tianyu Kingdom!" ”

At this time, Yu Lingmo also rarely showed his other emotion in front of others in addition to his cold face.

Yu Lingmo was also excited in his heart, once this picture of the windmill was successfully manufactured, how many people would benefit and how many lives would be saved!

"Yes, sister, you're amazing!"

Ouyang Yu also sighed proudly, thinking to himself, he had to quickly tell his father and mother the news, so that they would be happy and happy, let them know what an amazing daughter he had raised, and he also had a very amazing sister!

Obviously, Ouyang Hao thought the same way, because when he received Ouyang Yu's eyes, he nodded.

smiled at Ouyang Ning and said, "My sister has compared my second brother!" ”

Although he said this, Ouyang Hao's tone did not have a trace of jealousy, but was full of pampering and pride.

"Big brother and second brother, I advise you not to tell your father and mother about this first, it's not too late to wait until you try the effect." Ouyang Ningxin looked at the movements of the two of them, and knew what idea the two wanted to fight, and reminded them loudly.

The two of them were suddenly hit in their hearts, and they wanted to show off in front of their parents, but now it's okay, a word from their sister organized all the actions in their hearts.

"Got it." Both replied at the same time.

"Also, don't tell anyone about this yet, and tell everyone when it is successful." Ouyang Ningxin said to the man standing behind him.
