A few days later, on the banks of the Wei River, a large wooden frame was erected in each river, and wooden wheels were installed on the wooden frame.

Between the wooden frame on the shore and in the water, there is a row of piles facing each other.

A wooden board was placed between the piles to support the bamboo tube containing water.

Then use thick hemp rope to fix the bamboo tube and connect it to the wooden frame.

As the wooden frame in the river began to rotate, the bamboo tube immersed in the water was slowly pulled up along the wooden board. After passing the wooden wheel on the bank, the water in the wooden tube was poured into the canal.

A little accumulates into a large amount, and gradually gathers into a canal of water, flowing to a distant place.

"It's done?"

After working hard for so many days, when it came time to actually lift the water, the old craftsmen in the engineering camp couldn't believe their own eyes.

"It's done!" Feng Yong nodded and gave an affirmative answer, "Didn't I already make a small model and try it out? At that time, everyone said it would definitely work!"

With his lips trembling, the old craftsman rushed directly under the bamboo tube, stretched out his hands to hold the water, and truly felt the cool water, then he raised his head excitedly.

His face was wet, and he didn’t know whether it was the water droplets splashed on it or the sweat drops, but more likely tears, “It’s done!”

They all have a background in digging food from the ground, so why don’t they know how important this kind of water wheel is for farming?

As long as the flow continues, no matter how high the water bank is, water can be drawn up.

As the old craftsman started, everyone cheered loudly and rushed forward, trying to get to the front and really take a closer look at everything.

Some people even tried to touch the fruits of their labor over the past few days.

"What are you doing?"

Feng Yong shouted, "Can't you see this thing is spinning? Don't you know it's dangerous?"

All of a sudden everyone was drunk again.

They looked at Feng Yong with awe in their eyes.

"Everyone spread out, don't crowd too far forward, or what if you accidentally knock this thing over?"

Feng Yong waved his hand, and everyone quickly retreated.

"Prime Minister, come and take a look."

The majestic Feng Langjun turned around, changed his face again, and invited the Han Prime Minister to the front.

Zhuge Liang nodded slightly. Although his face was trying to remain calm, his eyes were always on the slowly rotating waterwheel, and he just walked over blankly.

Because I didn't pay attention to my steps, I staggered and almost fell.

Feng Yong quickly stepped forward to support him, "Prime Minister, be careful."

Zhuge Liang did not respond. He walked under the waterwheel and finally stretched out his hand hidden in his wide sleeves. Feng Yong standing next to him could clearly see that his hand was shaking slightly.

"Prime Minister, this wooden wheel is spinning, be careful not to get scratched."

Feng Yong whispered.

"Oh, okay, okay." Zhuge Liang replied, his hand stopping less than three inches away from the waterwheel, as if he was stroking a rare treasure from afar.

"With this thing, there is finally room for relief from the drought in Longyou."

Zhuge Liang seemed to be mumbling to himself, and seemed to be talking to Feng Yong. The smile on his face became thicker and thicker, and finally he laughed out loud, and his laughter gradually became louder.

Laughter infected the engineering camp standing outside. There were nearly a hundred people, young, middle-aged, and a few old craftsmen. There were nearly a hundred mouths, grinning almost at the same time.

The roaring sound seemed to evoke the resonance of the Weishui River, and everything near and far seemed to be cheering.

The farmers carrying water in the distance didn't know what was happening, so they could only look at it from a distance.

Zhuge Liang had laughed enough, then turned around and asked quietly, "Your drawing also said that if you connect the branches, you can use human power to make a vertical wheel, animal power, a crutch, and a foot pedal.

, yes or no?”

Feng Yong nodded, "If you encounter a place where the water flow cannot move the wooden wheel, you can attach these three objects to the wooden wheel depending on the situation, and use human or animal power to turn the wooden wheel, and you can also catch the water."

"Excellent!" Zhuge Liang received a positive answer. He held Feng Yong's hand tightly and said excitedly, "This matter is equal to military merit!"

There are thirteen states in the world, Cao Wei occupies eight states, Dongwu occupies two states, and the Han Dynasty only occupies one state.

Therefore, as the prime minister of the Han Dynasty, Zhuge Liang's biggest task is to explore the potential of the Han Dynasty as much as possible while weakening Cao Wei's power as much as possible.

Everyone present only saw that the waterwheel could alleviate the drought in Longyou, but Zhuge Liang could think further.

In places where river valleys are too deep for irrigation and farming, or where the terrain is too high for water to flow up, can this kind of waterwheel turn wasteland into fertile farmland?

Preserving more vitality for Longyou this year and alleviating the drought can only be regarded as one of its uses. It can also open up more wasteland and produce a variety of grains, which are also its huge uses.

"How many of these items can be made in one day?"

"This is not a rare item. If it were replaced by other craftsmen, it might be slower, but there are a group of young craftsmen from Nanxiang in the engineering camp, although their craftsmanship is not as good as those of the old craftsmen."

"But as long as they can make something, no matter how skilled the old craftsmen are, they can't make it faster."

Unified scale and unit are the basis for standardization.

Although from the perspective of future generations, the precision of hand-made parts is simply appalling.

But Feng Yong doesn't care.

As long as the parts error is within the tolerance range, as long as they can be mixed and assembled together, they are considered standardized parts. Are you going to bite me if you don’t agree?

Although this waterwheel was made by a few old craftsmen, the people who built it were all young apprentices from Nanxiang.

It's not about building a "strong and strong tree", standardization, do you understand standardization?

"Why isn't it strange? This is a rare thing among the people! The waterwheels made this year must be guarded by soldiers, and ordinary people are not allowed to approach easily."

Zhuge Liang directly set the policy.

"Prime Minister, why is this?"

Feng Yong was a little confused.

Zhuge Liang said "tsk", "There is a drought in Longyou, and Guanzhong must not be having a hard time. As for Liangzhou, it is even more difficult to get a drop of rain. If they know how to make this thing, wouldn't that be a favor to the enemy?"

?”

"I'm afraid this will only last two or three years at most..."

When Feng Yong heard this, he immediately understood, and then became a little worried.

There are no patent protection laws these days.

Even if there were, Thief Cao would definitely not pay the patent fees.

I'm afraid they will hate themselves to death now: first they emptied Guanzhong of food, then burned Longguan, cutting off the road to quickly support Longyou, and finally blocked Zhang He at the street pavilion, allowing Cao Wei to take back Longyou

The last hope was dashed.

It would be polite not to give yourself an axe.

"Two or three years is enough. I didn't expect it to last long." Zhuge Liang didn't expect that much. "Just like the curved shaft plow, it took two or three years to spread to Cao Wei. It's already considered that we have tried our best.

"

It is not convenient to spread information these days. Even if a country makes great efforts to promote it and spread it from north to south, it will take at least twenty or thirty years.

Just like a curved shaft plow, even an ordinary carpenter can easily imitate it using wood.

But it is only in Shu. Even with the strong and powerful presence of Old Demon Zhuge, after five years, I can only say that it has spread to every county, but it is only a county.

There has to be a question mark as to how many of these grassroots units in Xiangting have been popularized.

As for the Eight-Niu Plow, if ordinary people can see it in the village of a wealthy family, it is considered very knowledgeable.

What's more, something as complicated as a high-tube waterwheel is more complicated than a curved shaft plow.

The poor intelligence of the people, coupled with the slow speed of information dissemination in ancient times, various stubborn ideas, the efficiency of the feudal bureaucracy, etc., are all obstacles that hinder the development of new things.

What's more important is that if the imperial court wants to promote new things, it doesn't just issue a document directly like later generations did.

That requires people to transport the physical objects to the place, and then let the local officials discuss with the village elders. At the same time, the court has to send craftsmen who are good at making to follow.

The cost of promotion, production, transportation, and the costs incurred in each link are simply an astronomical figure.

Without a strong unified government, without a very generous finance, and without a long enough time, it is simply a delusion - long enough means that ten years are used as the basic unit of calculation.

There are also those village elders and the like, whether they are willing to accept these new things is also a big question.

The shortcomings of imperial power not going to the countryside were clearly revealed at this time.

Even if the central government has the ability and willingness to bear the cost, the unscrupulous people below are unwilling to accept your kindness, so you can only stare and jump.

The government efficiency of the Han Dynasty must be higher than that of Wei and Wu. The old demon Zhuge must be very confident in this, so he said these words.

"With this waterwheel, I can finally teach my teacher with peace of mind."

Zhuge Liang had a look of relief on his face.

Tianshui County is the essence of Longyou.

During the Later Han Dynasty, 60% of Longyou's population and grain production were in Tianshui.

Even though Cao Wei began to pay attention to Guangwei County in recent years, Tianshui is still the most important of the four counties in Longyou due to its geographical location and historical reasons.
