On the bank of the Ba River, five waterwheels were rotating.
Each waterwheel was connected to three connecting rods. The connecting rods moved with the rotation of the waterwheel, giving people the feeling that they were extending and contracting.
In front of each connecting rod, there was an old-fashioned rice threshing machine from Li Yi's time.
The threshing machine was connected by several wooden bearings and connecting rods. The most crucial part was a hollow barrel made of wooden planks.
On top of each wooden plank was an iron wire ring. When it rotated, these rings would be used to beat down the rice or wheat grains on the stalk.
In addition to the threshing machine that was driven by the hydraulic system, there were also two foot-operated machines.
A large group of people were watching. Zhuangzi's people were very unhappy. How could they let others see their treasures?
But they had no choice. Dongzhu allowed others to see.
Zhuangzi's craftsmen checked the equipment and dripped soybean oil on the shaft and connecting rods to lubricate them.
"You can also use other vegetable oils." Li Yi introduced them to his big brother and third brother.
Li Longji and Li Chengqi expressed that they understood. The axle of the waterwheel they were riding in also had to be dripped with oil. Otherwise, the wood would be burned by the grinding.
Of course, the waterwheel didn't need to do that. The waterwheel had water as lubrication.
However, the axle of the waterwheel had to be soaked in oil before it was used.
Everything was ready. Li Yi personally picked up a handful of wheat stalks.
He went to the foot-operated threshing machine and stepped on it. The connecting rod moved, causing the wooden barrel to rotate.
He put the wheat stalks in his hand on it. Crackling, rumbling, rumbling, the threshing machine's sound and the sound of wheat grains being beaten down sounded at the same time.
After a few breaths, a handful of wheat grains on the wheat stalks were beaten down.
Li Yi took another handful of wheat stalks and repeated the operation.
Crackling, rumbling, rumbling, it was solved again.
Li Longji personally learned from Li Yi and operated another foot-operated threshing machine.
After a few times, he put down the wheat stalks and stood there without saying a word.
"Start." Li Yi ordered.
The 15 people guarding the threshing machine connected to the threshing machine at the fastest speed when the connecting rod of the waterwheel reached over.
In fact, it was just a loop that was put into the protruding part of the rod, and then the waterwheel would drive the thresher on the connecting rod to operate.
One person stood in front of each threshing machine, took a handful of wheat straw from someone else, and put it on the threshing machine to remove the grains.
One person passed it to the other, and the other hit it. Their coordination was very good, and their speed was very fast.
For a moment, the entire riverside was filled with crackling and rumbling sounds.
The other spectators looked on in a daze. Some had their mouths wide open, some had their eyes wide open, some were scratching their ears and cheeks, and some were clenching their fists …
None of them dared to speak for fear of offending the sacred scene.
Li Longji raised his head and two streams of tears flowed down.
Empress Wang pursed her lips and her eyes turned red.
The people watching from Zhuangzi tried their best to stand up straight. At this moment, the glory belonged to their Dongzhu.
A moment later, Li Yi broke the silence, "Big Brother, Third Brother, can you make this thing with five catties of iron?"
"Ah?" Li Chengqi was startled.
Then, he nodded his head vigorously, "Yes, yes, it's worth fifty catties of iron. It can be done so fast. Third Brother, the Tang dynasty doesn't need to spend a lot of manpower on threshing anymore."
Li Longji punched the palm of his other hand, "Treasure, the treasure of the Tang dynasty. This thing can be shared by several families or even more than a dozen families. Five catties of iron is not much. "
"Big Brother, Third Brother, if there is no iron, bamboo can also be used. But after it wears out, it needs to be replaced with bamboo strips."
"It's best to cut the bamboo tube horizontally and fix it on top."
Li Yi said as he thought of a way. There was no circle made of iron wire.
Old bamboo was cut out in circles and connected to the wooden barrel board with the method of riveting. The result was not bad.
"Good idea. Brother Yi is a genius." Li Longji reached out and touched Li Yi's head.
Li Yi also touched it. Empress Wang naturally rubbed Li Yi's hair.
Li Yi: "…"
He tied his hair again. It was long and almost reached his shoulders.
"Puff!" Zhang Xiao, the village chief of the Zhang Family Village, came to Li Yi and knelt directly.
"Mr. Zhang, what are you doing? Get up." Li Yi stepped aside and reached out to help him.
Zhang Xiao turned and continued to kneel, "Li Dongzhu, what do you want? Anything that the Zhang Family Village can offer will be given to you. "
"Alas! I don't want anything. You can ask someone to learn it later. "Li Yi said and went to help him again.
Zhang Xiao was stunned. Until he was helped up, he still stared at Li Yi in disbelief.
Li Yi turned his head and said to Li Chengqi and Li Longji, "Big Brother, Third Brother, please help to promote this thing."
"Brother Yi, you … don't want any benefits?" Li Longji stared at him.
"Of course, why wouldn't I?" Li Yi said.
Then he said, "The benefit I want is to be in a good mood. In the Tang dynasty, there is no cold everywhere. There are tens of thousands of buildings. The summer is cool and the winter is warm. The old can raise the children to smile. "
"Okay, okay, Brother Yi, I believe you." Li Longji patted Li Yi's shoulder again and again.
Li Chengqi nodded and agreed.
If it were someone else who said this, he would have slapped him. Why are you so noble?
But Brother Yi must be right.
Because before Brother Yi said this, he did it.
Brother Yi's Zhuangzi raised scholars. He gave meat to the villagers every meal, made beautiful clothes and school bags for the children, and studied together.
When they fell sick, Brother Yi would do it himself.
When others came to Zhuangzi to sell things, Zhuangzi would always give a high price.
Brother Yi brought out all kinds of good skills and never said anything in return.
"Li Dongzhu, you, you said you would give it to us for free?" Zhang Xiao finally recovered.
His face was pale and he was sweating. He asked in an uncertain tone.
Li Yi said in his heart, "How can I give it to you for free? If everyone uses it, I can increase my lifespan a lot."
Although he was thinking about it, he still asked, "Village Chief Zhang, do you have a copper coin?"
"Ah? Yes. "Zhang Xiao didn't know what Li Yi meant and took out one copper coin.
Li Yi took it and said, "One copper coin. I'll sell this method to your village."
Zhang Xiao was stunned again and then bowed deeply. "Li Dongzhu, if you have any orders in the future, the Zhang Family Village will not dare to disobey."
The other merchants who came to buy soy sauce were tempted. It was a good thing.
What was this thing? It threshed wheat as if it was flying.
Wheat was fine, but rice was even better.
With this treasure, they didn't need stone rollers or flails.
They stepped on it with their feet, and a lot of wheat fell down.
How much labor was saved? They didn't need to waste so much time and energy.
They could do other work for the rest of the time.
Compared to flails, one person with this treasure was equal to a hundred people.
As for stone rollers, they didn't need animals to pull them. It was simply terrible.
If the animals were tired, they would eat more.
If there was a river near the village, they could set up a waterwheel and everyone in the village could use it.
Everyone looked at the threshing machine. They were even more shocked than the people in Li Yi's village when they first saw the combined harvester.
The waterwheel turned slowly, and 15 water-powered threshers kept threshing the wheat.
The people in Zhuangzi felt very proud of their work and had a sense of superiority.
As for the other two threshing machines, there were also some farmers who came over and stepped on them to use.
The others carried the wheat stalks over and the threshed ones were taken away to clean up the field.
There were only a few small pieces of foam, and it was much easier to clean up than the crushed ones and flails.
The others looked on enviously and waited for Li Yi to take out the production method.
The scholars and students were also watching the show. They were stunned and tongue-tied.
They turned their heads and began to think about how to write an article to praise, because there would be more wheat flour to eat.
During the summer harvest, Zhuangzi wouldn't sell grain. Naturally, everyone would eat it.
Moreover, it had already been decided that after the wheat was planted, they would plant rice.
The rice harvest was white rice.
Therefore, they had to praise Dongzhu. They had to praise him to the heavens and let everyone know. Otherwise, they wouldn't be able to live in a house for free and eat for free.
They had to be loyal to the ruler.
They couldn't let Dongzhu's heart turn cold.
