Gu's backyard.

Gu Zhang's face was solemn, and he was holding pieces of wood in his hands.

Old Man Gu has been quite tired recently, but when he heard that he could raise the water in the river and flow to the fields by himself, he still created the materials that Gu Zhang wanted with great expectations.

Gu Zhang was actually not completely sure, after all, he had only seen this thing in books.

When drawing, if it is not a small picture that refers to the product interface of the system, he may not be able to draw it.

But in fact, if you understand the principle, it is not too complicated.

The sink and scraper go deep underwater, and then use manpower, water power, animal power, wind power, etc. as power to drive the wooden chain to rotate continuously.

In this way, a circle of scrapers can lift the river water to the shore along the trough.

Although it can only lift water one or two meters high, it is much easier to make than a large water wheel car with a height of more than ten to twenty meters, after all, the river flowing through Yonghe Village is not too low, and there is no need to lift water forty or fifty meters high.

Gu Zhang's dark eyes stared at each part, and the structure and principle of the keel car kept emerging and perfecting in his mind.

The sink is the first to be spliced, and then the flap in the middle, which is the passage for transporting water.

This is followed by the most important part of the front and rear ends, the front is to be sunk into the water in the U-shaped flap, and the large axles on land need to be attached to the crutches in order to be pedaled.

Gu Zhang took a few steps back, checked a few times, and saw that there was nothing missing, so he tried it.

"Click-"

Because of the rush of time, the structure was simplified and rough, and when it was turned, it suddenly made a clicking sound.

But it's all real materials, and there is no major problem with the structure, so it works normally.

Gu Zhang nodded with satisfaction.

Finally, a rough wooden frame assembled from two shelving logs at home was installed, so that the upper end of the keel car could be fixed to the river bank.

After two hours of work, a long wooden shelf that looked like it was patched together and tattered, and it was erected in the backyard of the Gu family at an angle, and from a distance, it really looked like a keel.

"Little rock, this is what you said about the car that can carry water by itself?"

Gu Dagen, Qiu Niang, and Old Man Gu came back from outside sweating profusely, and one of them took a stoneware bowl and drank water.

His eyes looked at the "wooden frame" next to Gu Zhang without blinking.

"Is this the pile I left behind in the morning?" Old Man Gu couldn't believe that this big guy was actually those wooden chips, planks and sticks he had made in the past two days.

Hearing the movement, Gu Zhang also came over and took a bowl of water, which he deliberately boiled and cooled here in advance.

Gu Zhang said: "It's the ones you made that you put together, grandpa." ”

The keel car sounds complicated, but in fact there are many repetitive structures, long sinks can be put together with the simplest mortise and tenon joints, wooden planks can also be used as flaps, and wooden sticks can be used as flaps.

It also took a little more effort to the details and key points.

Gu Zhang is still quite satisfied with this keel car, in the case of such a lack of materials, it can still have this appearance, at least it can get a passing score, right?

He asked, "Have we finished watering our fields today?" ”

Gu Dagen wiped his face with a sweat towel that had just been soaked in cold water, and he said, "There is still the last half an acre, and half an hour after eating is enough." ”

"Then let's have dinner and go directly to try this keel car."

If it's okay to go into the water tonight, you won't have to carry water back and forth like this many times from tomorrow onwards.

Especially the two acres of land that have been cleared out of the land, the location is not good, and the daily watering is the most tiring.

Gu Dagen's towel to wipe his face fell to the ground, why don't you give it a try tonight?

This...... That's good?

Gu Dagen hesitantly looked at the rather "miserable" wooden frame: "This thing can make water flow to the field by itself?" ”

Gu Zhang pointed to the small back basket full of bamboo tubes in the corner: "Add that one." ”

OK!

The small stone was actually made, like a god, something that could make the water flow to the field on its own.

It's like this, stumbling a little beyond people's imagination.

Until the end of the meal, the Gu family frequently looked at the keel car.

Even the fine grains that I was reluctant to eat in the past didn't taste much, and they were in the aftertaste of disbelief.

After eating, Gu Zhang took Gu Dagen's hand and took him to the keel waterwheel: "While it's not dark, let's hurry up." ”

The wooden frame propped up one end of the keel car, and it was very convenient to drag it away, Gu Zhang also said: "When the fertile land is finished, we can also change the water intake point closer to the two acres of land that have been cleared." ”

Can it still be like this?

The Gu family was still a little confused until they went out.

It wasn't until I walked out of the door and met many men who had also finished eating and were going to work again that I gradually came back to my senses.

"Big root, what is this wooden shelf for?"

"What are you dragging such a big guy for?"

"After a day's work, aren't you tired? How can you still have the energy to toss carpenter's work? Qiu Niang wants to make money and wants to go crazy, and treats her own man as a cow. ”

Originally, Gu Dagen was still worried about whether he would succeed and didn't know how to answer, but when he heard this, he immediately said: "This is not the carpenter job that Qiu Niang took over, it is something made of small stones to carry water from the river." ”

“！”

The crowd who was watching the bustle, with few laborers at home and walking to the field without finishing their work during the day, suddenly pricked up their ears and moved their eyes back.

Carrying water from the river?

They first looked at the keel car, and then looked at Gu Zhang in shock, but saw that he was so calmly following the wooden shelf, as if he was watching some kind of excitement, looking at them with a smile?

These days, in the entire Yonghe Village, no one is exempt from the pain of carrying water.

Every day when it doesn't rain, they have to fetch water from the river every day, even if the village chief's house has an ox cart, because the family has a lot of land, they are tired enough.

That's it.

It is a great luck that it is hard to be tired, and it does not affect the harvest.

However, some families have too few strong laborers, or the location of the fields is not good, and they are far away from the river, and they are busy from morning to night, and they have no time to water every field.

It is the critical time for the wheat ears to grow and become full, and seeing that because of the lack of water, the wheat grains do not grow at all, and even deflated, and my heart is full of panic.

Some people even looked at the endless work, fell into the field, and wept and bowed to the heavens, "Please, God, send a kind heart to make it rain." ”

At this time, it can't be said that they are relatives Bo Liang, and they also have to take care of their own fields, so they have no spare energy to help.

The lack of rain has made it difficult for all the low-level farmers who depend on the weather to live.

"Are you going to try it? Then I'll check it out. ”

In addition to the work in the fields at home, there is still a lot of work, and many people are following behind the Gu family, planning to take a look.

There were still some dishes that hadn't finished yet, and they couldn't help but follow with bowls.

Got to the river.

Gu Zhang glanced at the water, compared with the water level in his memory, it had dropped a lot, and some stones were exposed on the shore.

"Little stone, how do you use this thing?" Gu Dagen carefully put the keel car on the shore and stopped.

Gu Zhang chose a suitable water point by the river, pointed to that place and said, "Dad, you hold on to the shelf and put it down from here." ”

Gu Dagen glanced at the keel car, his movements became more and more careful, he held the wooden frame with both hands, and put the other U-shaped flap into the water.

Seeing that the keel car had entered the water, the whole keel car leaned against the shore.

"Okay, okay, that's it," Gu Zhang pointed to the place in front of him again, "Just put the wooden frame here and fix it." ”

Gu Dagen did so.

In this way, the whole keel car leaned against the bank of the river.

Before everyone could ask, there was a "click" sound in the water.

In the sound of running water, the sudden appearance of the sound is particularly eye-catching.

"It's not going to fall apart, is it?"

It's not that they haven't seen wooden furniture, big boats, and the world when the men of the village go out to work.

But I've never seen such a "click" tool.

Is there really no problem?

The rushing water constantly washes the flap, and the flap keeps hitting the water upward, and the water rises along the long trough.

Probably because the keel car is really too simple, a lot of water leaks through the gaps, and the water power cannot be converted into thrust, so the water rises very slowly along the long trough.

Half of the village gathered, their eyes unblinking, watching the rising water.

Did you really let the water come up on its own?

Gu Zhang frowned, he thought this was a little too slow.

He simply stepped forward, stepped on the big bare rock next to him, and stood next to the wooden crutch of the keel car.

I stepped on it.

Everyone: "??? ”

What is this doing?

"Little stone, come down quickly." The big pillar stepped forward, nervously trying to take the man down so as not to trample on the new thing.

Gu Zhang blocked it with his hand and explained: "It's a bit slow to rely purely on water power, it's about to get dark, so I'll speed it up." ”

Dazhu was stunned, and his hand that wanted to hold the child stopped in mid-air.

Can this thing be sped up?

Gu Zhang stood up and stepped on it like a bicycle.

There was already a hydraulic push, and it was not difficult to step on it at all, Gu Zhang stepped on it twice, and after adapting to it, he accelerated to step on it.

I saw that the sound of "click, click, click" under the water suddenly turned into a "click, click, click!" that was smashed down by a storm! ”

The water level, which had been slowly rising along the long trough, was rapidly rushed upwards under the impetus of the rapidly flapping flap.

It's as if this is where the water should go.

Gu Zhangren was on a high place, bowed his head and shouted, "Master, you take out the things in the back basket and fight one by one." ”

"Oh...... Oh! I'm going to fight. Master Gu hurriedly put down the back basket, he was used to doing farm work, and it couldn't be easier to put together the hollowed-out bamboos according to the openings.

Before he had finished two sections, the water had already flowed out from the top of the trough like a fountain, making a beautiful arc in the air.

The sound of the water hitting the ground and the water smashing into the ground echoed in everyone's ears.

The fine splash of water in the air makes people feel a lot cooler.

The water has been sent to a high place, and it is flowing out in a steady stream, and if you look at the bamboo in the old man's hand, no matter how stupid you are, you will know what is going on!

***

The county seat yamen.

Wu Xian Lingzheng smiled and poured tea for an old man with pale sideburns, thinking in his heart that he shouldn't have done anything too much for a while.

But don't let the person in front of you catch the wrong place, although it is Zhishi, but I don't know how many people are still in Beijing, he has to be careful.

The old man with pale sideburns took a sip of tea, but he didn't taste the fragrance of tea at all, his mind was not on this, and he said worriedly: "There is moisture in the grout, the seeds are full of ears, and now it has not rained for a few days, can there be a good prescription for Wu County?" ”

Wu Xianling's tension suddenly eased a lot, and he smiled: "Elder Yan Shu may not know much about the situation on our side, the county seat under the city of Ningdu Mansion is close to the river, and there has never been a shortage of water for many years, so you don't have to worry about it." ”

Yan Xianmei's expression was slightly solemn, she took another sip of tea, and sighed softly in her heart, she was a confused official who didn't ask about farming.

***

"How much bamboo is left in the basket? I'm here to help, too. ”

"It's dangerous on the small rock, you come down and change your uncle to step on it!"

Half of the village gathered by the river, looking at the keel car with anticipation, eager to rush up and try it themselves.

Even Little Stone, a little doll less than nine years old, can step on it, so if they come, won't the water flow to the field?

But no one can compete with Gu Dagen as a father.

I saw that his face was full of excitement, as if he was tired from daywork, the pain on his shoulders disappeared, and he stepped on the stone to board the keel car in one step.

Because of the thicker and thicker arms that carried water, he couldn't wait to hug his son down, and said excitedly: "Little stone, you rest, dad comes!" ”

Gu Zhang: "......"

He looked at the sturdy father, worried about the rattling keel car, and reminded: "Dad, don't use so much strength, it will fall apart!" ”

"Daddy knows!" Gu Dagen was on it and stepped on it with a sigh.

The water flowed faster, as if there were countless people, pouring water from the top of the long trough in a continuous stream.

"Big root, come down, let me try!" Dazhu couldn't help but shout to his brother.

A group of people responded one after another, and this new thing that can continuously lift water from the river is hot to watch.

The splashes of snow-white water, the smiling faces of joy and contentment, accompanied by laughter and shouts, echoed throughout the riverbank.

Gu Zhang didn't even notice it, he smiled lightly when he looked at this scene, and his dark eyes were as bright as stars.

The water shimmered in a golden dusk, as if it melted into his eyes.

Just when many men were scrambling to go up and try the keel car, the bamboo on Old Man Gu's side was also completed with the help of everyone.

Gu Zhang shouted to the people above: "Uncle Dazhu, stop first, we are going to send water to the fields!" ”
