After calming down and thinking about it, Chen Zhe found that building a waterwheel is not a simple matter, and if you want to reproduce the crystallization of the wisdom of the ancient working people, you must understand its structure.

"All I know is that the waterwheel is a large moving machine, a tool that uses the inertia of the water potential to irrigate agriculture...... As for the structure of the waterwheel, I only know the rough shape of it......"

Chen Zhe said depressedly in his heart, and at the same time, an idea appeared in his mind.

If, like the previous handspinning wheel, you create a plausible fake waterwheel, and then use the item upgrade system to upgrade it, then everything will be fine?

But as soon as this idea came to mind, Chen Zhe shook his head and dispelled it.

When I built the hand-spinning wheel before, I could do this, because the hand-spinning wheel is smaller, and the production process is relatively simple, so I can carry Yan'er and Da Qiao to operate secretly, and then upgrade it unconsciously to surprise the girls.

But today's waterwheel is a rather huge project, and it is bound to be not something that Chen Zhe can complete alone, and when the time comes, Da Qiao, Xiao Qiao, Yan'er and Meixi will definitely come together to help.

In such a situation, if Chen Zhe didn't know the structure of the waterwheel, he wouldn't be able to guide the construction of the four girls at all, and he was afraid that he would be ganged up just after the start of construction.

Of course, this is not possible, Chen Zhe cannot take this risk.

So he had to think of another way to build a waterwheel.

"Structure, structure, structure...... Structural ...... of waterwheel"

Sitting on the edge of the sailboat, Chen Zhe kept thinking in his brain, and then he saw a flat stone slab not far away, so he took this stone slab casually.

Then pick up a sharp animal bone and use it to carve a painting directly on the stone slab.

According to the outline of his memory, Chen Zhe slowly tried to restore the waterwheel to the stone slab.

Since he did not know the complete structure of the waterwheel, he could only draw some general structures, and then use some imagination to label the waterwheel, regardless of whether the labels were correct or not.

Twenty minutes later, a design of a waterwheel carved on a stone slab, half by memory and half by imagination, was presented in front of Chen Zhe's eyes.

Chen Zhe spread the design flat on his lap, and then swept his gaze.

The system will give you a prompt:

[Item detected: A blueprint of a waterwheel with a donkey's lips not in the horse's mouth.] 】

Seeing this, Chen Zheqi's seven orifices were smoking.

"Damn, I've been painting hard for a long time, and you dare to say that my donkey's lips are not right for the horse's mouth?"

But after scolding, he laughed.

Since the system can recognize this design drawing of the donkey's lips not matching the horse's mouth, there is no doubt that the system can also repair this design drawing!

The current design of the waterwheel is indeed wrong, because Chen Zhe does not know how to design the waterwheel at all, he can't even understand the structure of the waterwheel, how can he design a correct waterwheel?

But Chen Zhe doesn't understand, the system understands!

As long as the system upgrade design drawing, can't Chen Zhe get a correct and complete design drawing?

Thinking of this, he hurriedly used the system to upgrade the design drawings without hesitation.

"Level up!"

With the consumption of popularity value in the background, the slate in front of him suddenly changed.

The slate itself was still on Chen Zhe's knees, but the patterns on it began to be rearranged, and the structure of the waterwheel drawn by Chen Zhe using his memory and imagination was completely overturned, and then turned into a real hardcore waterwheel!

Then the system will give you a prompt:

[Item detected: A decent design of a waterwheel.] 】

"Hmm...... Decent way. ”

Chen Zhe was very satisfied with this description, and looked down at the stone slab on his knee.

I saw that this time, the design of the waterwheel on the stone slab has become richer and more reasonable, and many details are depicted in detail and clearly.

Holding the slate and looking at it carefully, Chen Zhe felt that he could fully understand this design drawing as a layman of the waterwheel, and every detail and step was orderly and easy to understand.

This is enough to show that this design is very successful and can be used as a blueprint for building a waterwheel.

"Great. Chen Zhe smiled and nodded, he knew that as long as there was this design drawing, he could lead the girls to build a waterwheel.

Once the waterwheel is built, the ancient method of pressing the lamp oil can be carried out with the waterwheel, so that he can free his hands and no longer act as a hard laborer.

Holding the slate in his hand, Chen Zhe hurriedly turned around and walked towards the camp.

Another big project is about to start.

……

Back at the camp, the girls were basking in the sun under the banyan tree.

Sunny days are not often seen during the rainy season, and every inch of sunshine is a rare gift from nature.

Seeing Chen Zhe coming back from the river and bringing back a strange stone slab, Meixi asked curiously, "Chen Zhe, what did you bring back?"

Da Qiao glanced at the slate and asked, "Could it be a fossil?"

"Fossils?" Chen Zhe couldn't help but smile and shook his head, "Of course not, this is a tool that contains the infinite wisdom of our ancestors. ”

"Contained...... A tool of the infinite wisdom of the ancestors?" Da Qiao was stunned when he heard this, and Meixi was also surprised.

was intrigued by Chen Zhe's words, and the girls gathered around together.

Yan'er squinted her eyes and glanced at the slate, and then saw the detailed design sketched on the slate.

"Huh, there's writing on this slate, and there's a drawing...... Brother Chen, what is this? Is it a design drawing?"

"Yes. Chen Zhe nodded, "This is a design drawing of a waterwheel, which can help us build a waterwheel." ”

"Waterwheel?" Xiao Qiao tilted his head and asked, "Is the waterwheel the kind commonly used by the waterside in costume TV dramas, like big windmills?"

"yes. Chen Zhe nodded, "It is a smart tool that uses the potential energy of water conservancy, which can greatly improve our productivity." ”

Mi-hee knew Chen Zhe's thoughts very well, and after listening to Chen Zhe's narration, she understood his intentions.

"I see, Chen Zhe, you came up with this solution because we are running out of fuel, right?

The waterwheel was originally used to irrigate farmland, but there is no farmland on our island, and there is plenty of rain in the rainy season, so the waterwheel is used to provide an energy source for the ancient method of oil extraction. ”

"Clever. Chen Zhe couldn't help but nod in approval, "With the waterwheel, we don't have to do a lot of manual work by ourselves, especially the squeezing of lamp oil, the physical strength consumed by this work is still very large, as long as there is a waterwheel, we can free our hands." ”

There is no doubt that oil extraction has played a vital role in Chen Zhe's production activities.

Whether it is lighting at night or driving a car, all need to be squeezed to complete the oil, and everyone's demand for oil is still quite large.

The construction of the waterwheel determines the oil production on Chen Zhe's camp, as long as the waterwheel is built, then the future oil volume will be fully guaranteed.

"In that case, let's hurry up and build a watermill while the weather is still fine?" Da Qiao suggested.

Next, Chen Zhe first gave the drawings to the girls to circulate to each other, and everyone at least understood the structure of the waterwheel first, even if everyone was working together in the final work, it was very important to have a general understanding of the waterwheel in their minds.

Seeing this simple drawing on the slate, the girls were amazed.

Meixi took the lead and was the first to blow the rainbow fart: "Chen Zhe, I didn't expect your drawings to be so good, to be able to draw such standard manual drawings, you must have some architectural skills, right?"

Da Qiao nodded and said, "That's for sure, Chen Zhe must have studied architecture, otherwise he wouldn't have been able to build such a beautiful treehouse." ”

"That's right. Meixi said approvingly.

Yan'er looked at Chen Zhe curiously, tilted her head and asked, "Brother Xiao Chen, when did you learn architecture, why don't I know?"

As a neighbor of her childhood sweetheart, Yan'er didn't remember Chen philosophizing about architecture.

In order not to arouse suspicion, Chen Zhe could only smile and said: "Oh, I'm just interested in this aspect, I usually work behind closed doors at home and study it myself...... It's not worth mentioning. ”

"Not worth mentioning?" Da Qiao pointed to the drawings on the slate, shook his head and said, "Don't be modest, how can someone who can draw this kind of drawings not be worth mentioning in terms of architectural skills?"

Meixi also nodded and said, "Yes, in my opinion, this can be called a master's handiwork." ”

was touted by the girls for a while, Chen Zhe was really embarrassed, so he simply began to assign work and let everyone be responsible for a share of tasks.

Considering the amount of effort required to squeeze the fruit of the tung tree, Chen Zhe locked the diameter of the final waterwheel at five meters, which meant that they had to erect a huge wooden wheel five meters high, which was comparable to the amount of work Chen Zhe could build a handmade solid wood car.

In order to build a car, Chen Zhe directly cut down a whole shoe piper tree, and the height of a shoe piper tree is about 40 meters or more, so there is a lot of wood left after making the parts of the car.

In addition, because the waterwheel has to be in contact with the river water for a long time, the wood used to make the waterwheel must not be deformed by the water, so that some softer wood is excluded, and only the strong and reliable ebony wood meets this requirement.

After the work was assigned, Chen Zhe and the girls threw themselves into the intensive production, wielding a wealth of hand tools, and were busy in their own posts.

In addition to processing his own parts, Chen Zhe is also responsible for supervising the quality of the parts created by others, and if the quality of the parts manufactured by others is not up to standard, then Chen Zhe has to rework them.

The process of rework is also very simple –

Take the parts and walk to the place where no one is around, then use the item upgrade system to upgrade them.

- That's it.

With the help of Chen Zhe's item upgrade system, the parts created by each girl are the best of the best.

A day has passed, Chen Zhe and the girls have a high level of action, although the production of the waterwheel has just started, but at least the eight characters have been skimmed.

In the evening, it rained lightly on the island, and the work had to be suspended, so Chen Zhe and the girls went back to the tree house to rest, waiting for the rain to clear before proceeding to the next round of processing.

So dry and stop, stop and stop, a waterwheel was made for more than a week.

After another week, the construction of this large tool, which can convert the potential energy of water conservancy into labor, was officially completed.

The completed waterwheel was about five meters tall and needed a bracket to stand on the water of the nearby river, and because it was so large, it had to be assembled to erect it.

He is the only one in Chen Zhe's camp who has good arm strength.

Although Mi-hee has been practicing martial arts all year round, she is still a girl after all, and the strength of her big arms is limited after all, and she can't take on excessive labor.

In order to set up the waterwheel, Chen Zhe simply went to Liatila's camp and invited Clark over, so that Chen Zhe and Clark moved together with two tall and strong laborers, and only then did they successfully set up the waterwheel on the river.

At noon, this magnificent waterwheel finally succeeded in standing, and everyone was extremely excited to see this scene.

Liatila was even more shocked and exclaimed: "Yes, Chen Zhe, you can make an amazing invention every week on average...... One week ago you build a car, a week later you build a waterwheel......

What are you going to do next week? Why don't you just build a power station?"

Chen Zhe smiled and shook his head: "It's not that exaggerated, and I don't need to build any power station on the island, the reason why I want to build this waterwheel is completely for production activities." ”

"By the way, I haven't figured out why you built the watermill......" said Liatila, "show me how." ”

"No problem. Chen Zhe smiled, then turned to Yan'er and said, "Yan'er, let's start." ”

"Okay. ”

Yan'er nodded obediently, and then brought the rattan basket next to her, which was full of the fruit of the tung oil tree that had been boiled.

Chen Zhe poured the fruit of the tung tree neatly into the oil cake used for oil extraction, and then stacked the oil cake filled with the fruit of the oil tung tree and placed it neatly under the rocker arm of the water wheel.

Finally, the mallet used to press the oil cake is installed on the waterwheel, and everything is done.

The river water drives the waterwheel to rotate, and the waterwheel drives the mallet at the end of the rocker arm to rise and fall one by one.

The potential energy contained in the river water is very large, which also makes the mallet very strong.

Each blow was far superior to Chen Zhe's arm strength alone, so after only hitting more than ten times, the oil cake filled with the fruit of the tung tree had already begun to ooze thick oil.

Seeing this, Lia Tila finally came to her senses.

"I see...... That way your camp will run out of oil. ”

"Yes. Chen Zhe smiled, "In fact, not only lamp oil, but also the fuel of our cars is refined from this oil, so you can imagine what kind of significance the waterwheel has to our daily life." ”
