Bo Zhong was naturally very happy to see Su Heting, and took advantage of the time before the meal to ask a few questions.

Su Heting patiently and meticulously explained, and also said a few similar example questions, and extended some knowledge points.

His explanations have always been simple and interesting, so not only Bo loves to listen, but Zhong Ling and Shu Yu also listen to them with relish.

Aunt Zhang went to deliver the food from the shop in front of her, and Yuan Ning asked them to eat quickly.

After eating, my younger siblings have to go to school after a short break.

And she accompanied her little sister for a while, and she had to go out with Su Heting.

After the meal, Yuan Ning first coaxed Ji Xiu to sleep, said to his younger brothers and sisters, changed into neat men's clothes, and then went out with Su Heting.

Fang Yan led two donkeys to wait according to the time and place agreed in advance, and when he saw them come out, he was still asking: "Childe, do you really need me to accompany you?" ”

"No need," Su Heting waved his hand, "you just do your own thing." ”

Fang Yan pouted, and watched the two of them get on the back of the donkey, kicking and stepping away, before turning around and going back.

The weather is already very hot now, the sun is sifting down, and after a while, I am sweating, and the exposed skin is burning for a while.

Su Heting was sweating profusely when he saw Yuan Ning, looked left and right, stopped, went to buy two straw hats, and gave her one.

It is a wide-brimmed straw hat that has no top and is very breathable. And the wide rim just protects both shoulders, which can block most of the sunlight that falls on the body.

Yuan Ning felt a lot more comfortable, and asked again, "Where are you taking me?" ”

Su Heting handed over a pot of water, "I added mint and hay here, which is very cool and thirst-quenching." ”

Then he said, "You'll know when you get to the place, and I can't tell." ”

They went east except for the county seat, which is the most fertile area near the county seat of Tianqing.

Soon they came to a field.

Sorghum and soybeans are planted in the field, and the soybean seedlings are not tall.

Because some time ago, the summer harvest was over, and the wheat was harvested, and these soybeans were planted after the summer harvest.

Yuan Ning turned his head to look at him, "Why are you showing me this?" ”

The road is not very easy to walk, but fortunately, the donkey is an animal that can walk steadily no matter what the road conditions are.

Turning onto a sheep intestine path, Su Heting wiped his sweat, "It's almost there." ”

Yuan Ning had no choice but to follow silently, and he also knew in his heart that it was impossible for this person to do anything unfavorable to him.

After walking for about a quarter of an hour, Su Heting stopped, turned over and got off the donkey, and tied the donkey under a big tree.

Yuan Ning also got off the donkey, and Su Heting took the reins, tied them to his donkey, and motioned for her to go into the pavilion.

This is a well pavilion.

Sheltered by a thatched pavilion and the cool air coming up from the wellhead, it feels cool to sit on the well railing.

Su Heting came in and fetched a bucket of water, and poured it into the low-lying place next to it, "Wash your face, cool down, I'll tell you carefully." ”

Yuan Ning squatted at the puddle and washed his face, straightened his waist, looked around, and turned around to see Su Heting also washing his face, and took two broken bowls and scooped the well water and handed it to her, "Quench your thirst." ”

The newly drawn well water is cool and slightly sweet, and when you take a sip, it seems that half of the heat has been dispersed.

Su Heting also took a sip of water, took the bowl and sat back on the well railing, and said, "In the past, Tianqing County really relied on the sky to eat.

"Irrigating farmland is to divert water from the Qingyang River, which is ten miles away, but the Qingyang River is not very abundant, and sometimes there is too much water upstream, and there may be a cut-off.

"Therefore, if the year is good here in Tianqing County, there will be a good harvest of grain in the field, and if the year is not good, the grain harvested in so many fields will be pitiful.

"When I came here, I started digging ditches, building reservoirs, and digging wells while weeding out bandits. This basically solves the problem of irrigation. ”

He glanced at Yuan Ning, his expression was flat, "I don't say this to show off or invite merit, since I am the parent official of Tianqing County, it is all my duty to do these things."

"I would like to say that although we have drilled a lot of wells, each irrigation still requires a lot of manpower and material resources, and just watering and irrigating a piece of farmland is not only time-consuming, but also requires the cooperation of five or six people.

"Because after all, it's not that easy to get water from a well." He turned his head to look at the well behind him, and at the wheels on the platform.

Yuan Ning immediately understood, "You brought me here because you wanted me to help me think of a way to make people save time and effort to get water?" ”

"Exactly." Su Heting nodded.

Yuan Ning contemplated with his eyebrows, if there was a pump, it would be easy to say, but there were no power facilities here, and there was no pressure device, even if God airdropped a good pressure pump, it would not work.

You can try to do it, but the cost is a bit high for this era.

She was thinking, and Su Heting kept quiet so as not to disturb her.

About half an hour later, Yuan Ning said: "In this way, I'll draw a picture for you, and you can make some pulleys according to the drawing, and you can be as strong as you can." Then let's figure out how to use it.

"It's not a perfect solution, but it's better than it is now. In addition, these barrels can be remodeled, either at the bottom of the barrel or near the bottom of the barrel to make something that can be opened and closed.

"Wouldn't it be easier to get the water out without pouring it?"

Su Heting nodded hurriedly, "Okay, I'll let someone do it when I go back." However, I would like to ask if there is a better way. ”

"Yes, there is a ......" Yuan Ning shook his head, "but I still need to study it carefully, "It's easy to stay away, but the materials are not easy to match," and it may cost more. ”

Tianqing County is afraid that it will not be able to come up with this fund.

Su Heting's eyes lit up, "It's good if there is a way, you study it first, don't worry about the cost, I'll solve it." ”

Yuan Ning raised his eyelids and looked at him, "You don't want to pay out of your own pocket, do you?" I can tell you, as long as it is successful, there will be at least a few hundred places in the entire Tianqing County, and you can dig out as many families as you have!

"Besides, what you're going to do is definitely not water conservancy. There is still much that needs to be done to improve people's livelihoods.

"You can't pay for this and don't pay for it somewhere else.

"The most fearful thing is that if you improve the irrigation of a certain place, and the rest of the places have more than enough heart but not enough strength, the people will not read your existing achievements, but will scold you for being eccentric!"
