"A few old people! And a few sisters (who are the widows of the village)! Look! Qin Guangming gestured with his hands very seriously and said: "This field water ditch is to dig a straight line from here, as long as this field water ditch reaches the center of the field in our small village, other field water ditches are useless, but is there original...... Don't fill it in either, it may be useful in the future. ”

One of the village aunts asked, "What do you need water for other nearby fields?"

"Oh...... Good question for this sister! Qin Guangming stretched out his thumb and looked up, nodded approvingly, and explained: "If other nearby fields need water, then it is enough to connect directly from the fields close to the Tianshui ditch. ”

"Oh! I know what that means! Qin Gongzi meant to ......"

"What do you mean?"

"What Gongzi Qin said is ...... Put the field close to the field water ditch...... Bring in water, and then bring the water from this field to another nearby field that needs water, Qin Gongzi, I'm right? ”

"Yes! That's it! Qin Guangming nodded with a smile and said: "I see that the small village uses the same kind of millet seeds, and everyone is together when farming, and it is the same when water is needed. ”

"Oh! That's right......"

"I see......"

"According to what Qin Gongzi said, it is enough for our village to have a ditch for field water!"

"Yes! If...... If...... It's a lot easier to do that! ”

Qin Guangming nodded and said, "En! Right! That's it! ”

"But...... There is a lot of water in our small village in spring! Those old field water ditches are still useful! ”

"Didn't Gongzi Qin say it! The old field water ditch still has to be kept, isn't that reserved for the beginning of spring? ”

"Oh! Makes sense! ”

"Well, I think it's possible!"

But the aunt who came from behind didn't know, and hurriedly asked, "Master Qin!" You said digging a ditch for field water here...... What are you going to do? …… Why do you want everyone to dig a ditch for field water? What's the use of digging? There's no water here? The creek in the village was blocked by the village next door last night, so where is there water now? ”

"Yes! That village doesn't need water now! That village is not in a hurry to plant a second spring! ”

"Yes! What's the use of digging this ditch? If you don't do the same, you have to carry water to irrigate the fields. ”

"Yes! If you don't irrigate the fields, you can't even plant grains! ”

"yes!"

"Could it be...... Qin Gongzi ...... Do you want to ...... Can't float up the water in the big lake? ”

"Ah......h

"Young Master Qin! The big lake in front of us is at the bottom of the field in our small village, and there is no drifting shelf there. ”

"Even if it is erected, it can't float into the water, the water level of the lake is too low, every year in the second spring, our small village is basically picked, everyone said yes?"

"Yes, yes, yes......"

"Shut up!" An old man roared impatiently and angrily: "Didn't Gongzi Qin help us think of a way, he can pump up the water without a float." ”

"Is it a wheeled waterwheel?"

"Young Master Qin! There is no turning waterwheel here! ”

"yes!"

"Absolutely can't install it!"

"Why?" Su Youjin also thought of making a wheeling waterwheel at first, and he also thought that Qin Guangming thought that the solution was to make a wheeling waterwheel, since he heard someone say that he couldn't install a wheeling waterwheel, he asked curiously: "Isn't it possible to install a wheeling waterwheel here?" Or is the terrain bad? If it's not good, you can dig it well. ”

"Su Gongzi! You don't know, I'm not talking about that! ”

"That's not the reason why Su Gongzi, you just came to our village! I don't know what happens here in the village! ”

"Yes! I really can't install it! ”

Li Leiluo was a little impatient, and several widows chattered, and without saying the reason, they hurriedly came out and asked, "Why is that?" A few sisters might as well make it clearer? And let us understand that it is not. ”

"One is that people in small villages don't know how to make such a complicated wheeled waterwheel, and second, the cost of this wheeled waterwheel is too high." An old grandmother came out and slowly explained to Qin Guangming, Li Leiluo and Su Youjin: "As for the three...... Be...... This large waterwheel is too big, and it is cumbersome, and it also requires a lot of manpower, and you also know the manpower of our small village...... Alas! If you are not careful, you will be ...... by the next village I can't touch it. ”

"Ah...... Something else?? Li Leiluo gritted his teeth when he heard this, "Isn't there a royal law?" ”

"Alas! It's good that there is a royal law in this world! ”

"Alas......"

"Alas...... I thought these three boys had come up with some good idea! Alas...... Originally...... Originally...... It's a wheeling waterwheel! ”

"Don't think about it, three sons! It won't work! ”

Su Youjin also shivered in his heart when he heard this, and said in his heart: 'I'll go! What kind of world is this??? Don't let people live?? ’

The old men and grandmothers shook their heads and said, 'What do I think you're going to make?' It turned out to be a big waterwheel that was going to be built! Alas! Did you say it earlier? This...... This...... Isn't that a waste of everyone's time? And besides, this rotating waterwheel was built this year, and it will be invisible next year, and I don't know if it was made by the next village, or blown by the wind, or eaten by the fish in the lake, or the wheeling waterwheel ran away! Alas...... Anyway, everyone is talking about the situation! ’

Just when the villagers of the small village were about to disperse, and when Village Chief Chen was about to talk to Qin Guangming, Li Leiluo and Su Youjin about the secret letter, Qin Guangming finally spoke, "Don't leave in such a hurry!" I didn't say I was going to make that big wheeling wheel. ”

When everyone heard Qin Guangming say this, they were all shocked, stunned, their eyes suddenly came to their senses, and the feet that had been picked up from their feet were also retracted, and they all gathered around again seriously, and looked at Qin Guangming seriously.

"Actually, what I'm going to do is a simple wheeling staircase waterwheel!" Qin Guangming touched his smooth chin and thought for a while, made a rotating movement with his hand, and said, "It's the same as a long ladder, but it's very light and simple, and it's also very easy to carry." ”

"Oh...... Qin Gongzi! What is a rotating staircase waterwheel? ”

"We know the long ladder, but ...... The long ladder can only go up but not down! What did you bring water up with? ”

"That's right! And you can't turn yet, that's straight, what can turn? ”

The villagers of the small village suddenly "split the horn" again...... Splitting the trumpet, ......".
