Zhou Zhou knew that boys generally like adventurous and interesting things, so she wanted to design a model that could be used as both a weapon and a toy.

She believed that as a prince, he must have seen a lot of beautiful and interesting things since he was a child, so he understood how difficult it must be to invent something that would please him, but she was also a very adventurous person who liked to challenge herself, so she was not very worried and afraid, she believed in her own ability.

There were fifty or sixty drawings of the design, none of which she was satisfied with, but she slowly focused on her thoughts as she drew them—it had to be able to go up into the sky and into the sea, and it could be used as both a manned and an assault weapon.

Once this idea was formed in her mind, she was so excited that she immediately started to draw a model diagram with her brain.

To fly, you need a power unit that changes the airflow, so she figured out an ultra-thin spiral and set an artificial push rod under the spiral. When the human putter reaches a certain speed, the spiral can leave the ground and fly into the sky, and after the speed of the putter is reduced, it can slowly return to the ground.

Next, she designed thin planks for its perimeter to form a circular fortress-like thing. Then leave a row of holes around the fort and load the arrows from the inside so that the arrows of the arrows are exposed.

Thin planks were then added to the top of the fort and switches were installed that could be opened and closed.

Finally, she set up retractable oars on the sides of the fort and three water tanks at the base of the fort.

In this way, when the switch on the top of the fort is turned on, the ultra-thin spiral will rise above the fort under the action of the human push rod, forming an umbrella-shaped thing. Retract the spiral and when the archery device is activated, the arrows mounted in the fort will whizz in all directions. If someone in it keeps putting arrows in it, the arrows will keep firing out. When the slim auger and archery device are retracted and the paddle function is activated, it can sail in the river and sea, and if the launching device is activated. The small door of the tank will open and automatically fill the seawater, and when the tank is full, all the holes in the fortress will automatically close, and it can then dive into the water.

But the problem came again - the people inside the fortress would soon be unable to breathe if they were tightly sealed. This means that people will not be able to stay underwater for long while riding it.

How do you overcome the problem of staying underwater too shortly? Zhou Zhou started thinking again.

It didn't take long for her to get to the root of the problem - because there was no air underwater, even if you put aside the model, you can't stay at the bottom of the ocean for long, and the only way to solve it is to take the air with you.

So what do you do to bring air underwater?

Zhou Zhou pondered.

After thinking about it for a long time, she had a flash of inspiration - she could use a long tube to expose one end of it to the surface of the water and the other end to hold it in her mouth. That way people can stay underwater for a long time.

So what is used to make this kind of pipe?

Zhou Zhou immediately searched all over the house for materials.

But I searched for a long time and didn't find a suitable one.

She had to hand in the model tomorrow, and she didn't want to present the third prince with an imperfect design, so she continued to think of a way.

From the afternoon to the evening, she kept thinking, watching the time pass little by little, and she was as anxious as an ant on a hot nest.

Seeing this, her nurse helped to figure out a way.

After a while, the nurse said cautiously: "Miss, what do you think of the reed pole?" ”

Reed poles? Zhou Zhou's bright big eyes blinked, and then clapped his hands and said, "Yes, the reed pole is hollow." Okay, just use it. "Immediately send someone to the water's edge to look for it.

"If you don't have one near the water, go to the homes of the residents in that area and ask them, and you must find them tonight." Zhou Zhou instructed again.

When it was dark, the men sent finally returned with a large bundle of reed poles.

Zhou Zhou used it to make an air pipe that can be connected to the bottom of the water.

Immediately after doing it, she experimented with the model on the ground and in the water.

Her father, brother, and subordinates all came to her experiment, watching with bated breath.

The experiment was a success.

Everyone is proud of Zhou Zhou from the bottom of their hearts.

This is the most functional of all Zhou Zhou's inventions.

They were satisfied.

It's just that I don't know how the third prince feels when he sees it.

Thinking that it would be handed over to the third prince tomorrow, Zhou Junpu and Zhou Che were very nervous, but Zhou Zhou relaxed instead.

That evening, she packed it in a wooden box and handed it to Zhou Junpu, and after seeing him leave in the carriage, she let go of her belly and had a good meal.

After the meal, she went to bed.

She was so tired that she didn't have the energy to think about the reaction of the third prince when he saw it.

In the dimness, she heard the nurse calling her softly.

"Is it dawn?" She asked lazily, not opening her eyes.

"It's not dawn yet. It's the master who has come back and told you to go to his study immediately. ”

Zhou Zhou suddenly opened his eyes and found that it was still night, and the nurse Yang was sitting on the edge of her bed looking at her.

"Daddy is back? Does he look high? Zhou Zhou asked hurriedly.

"He looked very dignified." Yang said truthfully.

Yes? Could it be that the third prince is not satisfied with her design? She was suddenly panicked and lost. Tengdi got up, put on his clothes in three or two and went to Zhou Junpu's study.

Zhou Junpu really looked preoccupied.

"Daddy, is it that the third prince doesn't like that model?" Zhou Zhou asked straight to the point.

Zhou Junpu sighed and said, "I don't seem to be very happy with the third prince's expression." ”

"Did he say anything?" Zhou Zhou was anxious.

"He didn't say anything, told me to give you this letter." Zhou Junpu said.

It was an unsealed letter, and it was briefly written: The Qumin section of the Gong River is so deep and rapid that for a long time the residents on both sides of the river could only look at each other but could not get together. You have five days to design a rotatable, retractable bridge.

The font of the three princes is dancing with dragons and phoenixes, vigorous and powerful, and it can be framed as a work of art.

However, Zhou Zhou's mind at the moment was all about the content of the letter, so he had no time to appreciate the beauty of the font.

What the? She was given only five days to design such a high-tech bridge? Even the most famous bridge designer in Beijing probably had to spend ten days and eight days to conceive, right? Is he clearly embarrassed? The more Zhou Zhou thought about it, the more angry she became, she threw the letter on the table with a snap, and said angrily: "Daddy, please tell him that this task is too difficult to accept, so let him find someone else to design it." ”

It took her three days and two nights to design the previous design, and after he received it, he didn't say a word to come to another task of such difficulty, and no one would be happy.

What's more, her brain is still dizzy now.

So her stubborn temper was aroused at once, and she rushed out with red eyes and pouts. (To be continued.) )

PS: Dear friends, the first update is here. Thank you for the coin that Xiao P gave you a reward, Mo Da! The second and third more are in the old time. It is said that the author Jun was very similar to Zhou Zhou's sex when he was a child, thinking all day long about whether people can fly to the sky automatically, whether they can practice clairvoyance, whether they can live forever, and once went into the mountains alone to find immortals, climbed high rocks to find some kind of wild flowers, and was really fearless at that time.
